This blog post tries to explain their working. --------------------------------------------- https://adityatelange.in/blog/revshells/ ∗∗∗ Quickly Finding Encoded Payloads in Office Documents ∗∗∗ --------------------------------------------- Malicious documents like this RevengeRAT ppam file found on MalwareBazaar contain VBA code that you can analyze with oledump.py.

Some of the folks in this conversation suggested that instead of these things, we should be into more fundamental topics like “what is a pseudorandom function.” --------------------------------------------- https://blog.cryptographyengineering.com/2023/05/08/prfs-prps-and-other-fan… ∗∗∗ WordPress plugin vulnerability puts two million websites at risk ∗∗∗ --------------------------------------------- Millions of WordPress-powered websites are using the Advanced Custom Fields and Advanced Custom Fields Pro plugins, which security researchers say have been vulnerable to cross-site scripting (XSS) attacks. --------------------------------------------- https://grahamcluley.com/wordpress-plugin-vulnerability-puts-two-million-we… ∗∗∗ Cisco SPA112 2-Port Telefonadapter unsicher, es bleibt nur noch entsorgen ∗∗∗ --------------------------------------------- Die US-Anbieter Cisco warnt in eine Meldung vor einer kritischen Schwachstelle in einem seiner Telefonadapter.

The first one, aka CVE-2023-22620, is rated critical for an attacker to bypass the entire authentication and gain access to the firewall’s administrative panel. [...] The second one, aka CVE-2023-22897 is a heartbleed-like bug that allows the leaking of remote memory contents and is discussed in a second blog post. --------------------------------------------- https://www.rcesecurity.com/2023/04/securepwn-part-1-bypassing-securepoint-… ∗∗∗ SecurePwn Part 2: Leaking Remote Memory Contents (CVE-2023-22897) ∗∗∗ --------------------------------------------- While my last finding affecting SecurePoint’s UTM was quite interesting already, I was hit by a really hard OpenSSL Heartbleed flashback with this one.

If we know how RaaS gangs evade detection once in a network, for example, we may be able to kick them out before they can do any damage.

Unencrypted user data and commands. What could go wrong? A market-leading garage door controller is so riddled with severe security and privacy vulnerabilities that the researcher who discovered them, Sam Sabetan, is advising anyone using one to immediately disconnect it until they are fixed. Each $80 device, used to open and close garage doors and control home security alarms and smart power plugs, employs the same easy-to-find universal password to communicate with Nexx servers. The controllers also broadcast the unencrypted email address, device ID, first name, and last initial corresponding to each one, along with the message required to open or shut a door or turn on or off a smart plug or schedule such a command for a later time. Immediately unplug all Nexx devices --------------------------------------------- https://arstechnica.com/?p=1929120 ∗∗∗ Exploration of DShield Cowrie Data with jq, (Wed, Apr 5th) ∗∗∗ --------------------------------------------- There have been other diaries [1][2] showing how to explore JSON data with jq [3]. We'll review some options to understand unfamiliar JSON data and ways to filter that information. Using tools like Security Information and Event Management (SIEM) systems can help aggregate data and make it more easily searched and visualized. There are still times where being able to quickly search JSON data can be useful, especially if a SIEM option is not immediately available. --------------------------------------------- https://isc.sans.edu/diary/rss/29714 ∗∗∗ ALPHV/BlackCat ransomware affiliate targets Veritas Backup solution bugs ∗∗∗ --------------------------------------------- An ALPHV/BlackCat ransomware affiliate was spotted exploiting vulnerabilities in the Veritas Backup solution. An affiliate of the ALPHV/BlackCat ransomware gang, tracked as UNC4466, was observed exploiting three vulnerabilities in the Veritas Backup solution to gain initial access to the target network. Unlike other ALPHV affiliates, UNC4466 doesn’t rely on stolen credentials for initial access to victim environments.

Even though this initiative is relatively young, CISA says it has notified over 60 entities across the energy, healthcare, water/wastewater, education, and other sectors about potential pre-ransomware intrusions, and we’ve confirmed that many of them identified and remediated the intrusion before encryption or data loss occurred. --------------------------------------------- https://www.malwarebytes.com/blog/news/2023/04/pre-ransomware-notifications… ∗∗∗ Detecting Karakurt – an extortion focused threat actor ∗∗∗ --------------------------------------------- NCC Group’s Cyber Incident Response Team (CIRT) have responded to several extortion cases recently involving the threat actor Karakurt.

===================== = End-of-Day report = ===================== Timeframe: Freitag 24-03-2023 18:00 − Montag 27-03-2023 18:00 Handler: Robert Waldner Co-Handler: Stephan Richter ===================== = News = ===================== ∗∗∗ Guidance for investigating attacks using CVE-2023-23397 ∗∗∗ --------------------------------------------- This guide provides steps organizations can take to assess whether users have been targeted or compromised by threat actors exploiting CVE-2023-23397. A successful exploit of this vulnerability can result in unauthorized access to an organization’s environment by triggering a Net-NTLMv2 hash leak. Understanding the vulnerability and how it has been leveraged by threat actors can help guide the overall investigative process. --------------------------------------------- https://www.microsoft.com/en-us/security/blog/2023/03/24/guidance-for-inves… ∗∗∗ WooCommerce Credit Card Skimmer Reveals Tampered Plugin ∗∗∗ --------------------------------------------- Disclaimer: The malware infection described in this article does not affect the software plugin as a whole and does not indicate any vulnerabilities or security flaws within WooCommerce or any associated WooCommerce plugin extensions. Overall they are both robust and secure payment platforms that are perfectly safe to use. Instead, this article highlights the importance of maintaining good security posture and keeping environments locked down to prevent tampering from threat actors. --------------------------------------------- https://blog.sucuri.net/2023/03/woocommerce-skimmer-reveals-tampered-plugin… ∗∗∗ Framing Frames: Bypassing Wi-Fi Encryption by Manipulating Transmit Queues Affecting Multiple Cisco Products ∗∗∗ --------------------------------------------- On March 27, 2023, the research paper Framing Frames: Bypassing Wi-Fi Encryption by Manipulating Transmit Queues was made public. This paper discusses vulnerabilities in the 802.11 standard that could allow an attacker to spoof a targeted wireless client and redirect frames that are present in the transmit queues in an access point to an attacker-controlled device. This attack is seen as an opportunistic attack and the information gained by the attacker would be of minimal value in a securely configured network. --------------------------------------------- https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdviso… ∗∗∗ Visual Signature Spoofing in PDFs ∗∗∗ --------------------------------------------- Visual Signature Spoofing was partially successful in forging signed documents. Due to the limited support of JavaScript in the other PDF applications, it was only possible to create visual signature spoofs for Adobe Acrobat Reader DC. Other PDF applications may also become vulnerable in the future if they add support for the necessary JavaScript functions. --------------------------------------------- https://sec-consult.com/blog/detail/visual-signature-spoofing-in-pdfs/ ∗∗∗ Using an Undocumented Amplify API to Leak AWS Account IDs ∗∗∗ --------------------------------------------- In a previous blog post I mentioned that I was getting back into AWS vulnerability research in my free time. I’ve been taking a closer look at undocumented AWS APIs, trying to find hidden functionality that may be useful for an attacker or cross tenant boundaries. [...] I reported this API to AWS who responded that it did not “represent a security issue”, however, 3 days later, the API was disabled. --------------------------------------------- https://frichetten.com/blog/undocumented-amplify-api-leak-account-id/ ∗∗∗ Microsoft verteilt Sicherheitsupdate für Windows Snipping Tool ∗∗∗ --------------------------------------------- Microsoft hat ein außerplanmäßiges Sicherheitsupdate veröffentlicht. Es soll eine Schwachstelle im Windows Snipping Tool beseitigen – der in Windows 10 und Windows 11 integrierten Screenshot-App. Ähnlich wie zuletzt auch unter Android entfernt das Tool „gelöschte“ Bereiche von zugeschnittenen Screenshots nicht vollständig, sodass sie nachträglich wiederhergestellt werden können. --------------------------------------------- https://www.zdnet.de/88408044/microsoft-verteilt-sicherheitsupdate-fuer-win… ∗∗∗ Deprecation of Remote PowerShell in Exchange Online – Re-enabling or Extending RPS support ∗∗∗ --------------------------------------------- PowerShell (PS) cmdlets in Exchange Online use Remote PowerShell (RPS) for client to server communication. Unfortunately, RPS is legacy technology that is outdated and can pose security risks. As such, we recommend all customers move to the new more secure REST-based v3 PowerShell module, which will help us improve security – together. --------------------------------------------- https://techcommunity.microsoft.com/t5/exchange-team-blog/deprecation-of-re… ∗∗∗ OneNote Embedded URL Abuse ∗∗∗ --------------------------------------------- Whilst Microsoft is fixing the embedded files feature in OneNote I decided to abuse a whole other feature. Embedded URLs. Turns out this is something they may also have to fix. --------------------------------------------- https://blog.nviso.eu/2023/03/27/onenote-embedded-url-abuse/ ∗∗∗ Rhadamanthys: The “Everything Bagel” Infostealer ∗∗∗ --------------------------------------------- Key Takeaways: * Rhadamanthys is an advanced infostealer which debuted on the dark web in September of last year to a warm critical reception by cybercriminals. * A maximalist approach to features: functionality is added for its own sake, never mind the effort required or expected payoff. * Campaigns by default target countries indiscriminately, excluding the commonwealth of independent states. This is typical of this kind of malware. * Multiple-stage loader/shellcode execution has been researched in prior publications and has made it difficult to reach a proper interactive disassembly workflow with the actual information-stealing logic. --------------------------------------------- https://research.checkpoint.com/2023/rhadamanthys-the-everything-bagel-info… ===================== = Vulnerabilities = ===================== ∗∗∗ Cisco IOS XE Software Privilege Escalation Vulnerability ∗∗∗ --------------------------------------------- A vulnerability in the Cloud Management for Catalyst migration feature of Cisco IOS XE Software could allow an authenticated, local attacker to gain root-level privileges on an affected device. This vulnerability is due to insufficient memory protection in the Cisco IOS XE Meraki migration feature of an affected device. An attacker could exploit this vulnerability by modifying the Meraki registration parameters. A successful exploit could allow the attacker to elevate privileges to root. --------------------------------------------- https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdviso… ∗∗∗ ABB RCCMD – Use of default password (CVE-2022-4126) ∗∗∗ --------------------------------------------- A software update is available that resolves a privately reported vulnerability [...] An attacker who successfully exploited this vulnerability could take control of the computer the software runs on and possibly insert and run arbitrary code. --------------------------------------------- https://search.abb.com/library/Download.aspx?Action=Launch&DocumentID=2CMT0… ∗∗∗ Security updates for Monday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (libreoffice and xen), Fedora (chromium, curl, and xen), Red Hat (kernel, kernel-rt, kpatch-patch, and thunderbird), Scientific Linux (thunderbird), Slackware (tar), SUSE (apache2, ceph, curl, dpdk, helm, libgit2, and php7), and Ubuntu (firefox and thunderbird). --------------------------------------------- https://lwn.net/Articles/927451/ ∗∗∗ baserCMS vulnerable to arbitrary file uploads ∗∗∗ --------------------------------------------- https://jvn.jp/en/jp/JVN61105618/ ∗∗∗ IBM Security Bulletins 2023-03-25 - 2023-03-27 ∗∗∗ --------------------------------------------- https://www.ibm.com/support/pages/bulletin/ -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

===================== = End-of-Day report = ===================== Timeframe: Mittwoch 22-03-2023 18:00 − Donnerstag 23-03-2023 18:00 Handler: Robert Waldner Co-Handler: n/a ===================== = News = ===================== ∗∗∗ Developing an incident response playbook ∗∗∗ --------------------------------------------- Incident response playbooks help optimize the SOC processes, and are a major step forward to SOC maturity, but can be challenging for a company to develop. In this article, I want to share some insights on how to create the (almost) perfect playbook. --------------------------------------------- https://securelist.com/developing-an-incident-response-playbook/109145/ ∗∗∗ Cropping and Redacting Images Safely, (Thu, Mar 23rd) ∗∗∗ --------------------------------------------- The recent "acropalypse" vulnerabilities in Android and Windows 11 showed yet again the dangers of relying on image processing tools to redact images. [..] Here are some approaches to make image redaction safer. But please use them with caution. --------------------------------------------- https://isc.sans.edu/diary/rss/29666 ∗∗∗ German and South Korean Agencies Warn of Kimsukys Expanding Cyber Attack Tactics ∗∗∗ --------------------------------------------- German and South Korean government agencies have warned about cyber attacks mounted by a threat actor tracked as Kimsuky using rogue browser extensions to steal users Gmail inboxes. --------------------------------------------- https://thehackernews.com/2023/03/german-and-south-korean-agencies-warn.html ∗∗∗ AIIPot: Adaptive Intelligent-Interaction Honeypot for IoT Devices ∗∗∗ --------------------------------------------- In this paper, we propose a honeypot for IoT devices that uses machine learning techniques to learn and interact with attackers automatically. The evaluation of the proposed model indicates that our system can improve the session length with attackers and capture more attacks on the IoT network. --------------------------------------------- https://arxiv.org/abs/2303.12367 ∗∗∗ Memory Forensics R&D Illustrated: Detecting Hidden Windows Services ∗∗∗ --------------------------------------------- To begin the series, this post discusses a new detection technique for hidden services on Windows 7 through 11.

In many ways, this package typifies other token stealers that we have found prevalent in PyPI. However, one feature of this particular package caught our eye: an obfuscation technique that was foreseen in 2007 during a discussion about Python’s support for Unicode [..] --------------------------------------------- https://blog.phylum.io/malicious-actors-use-unicode-support-in-python-to-ev… ∗∗∗ Joomla! CVE-2023-23752 to Code Execution ∗∗∗ --------------------------------------------- On February 16, 2023, Joomla! published a security advisory for CVE-2023-23752. [..] disclosure was followed by a stream of exploits hitting GitHub, and multiple indicators of exploitation in the wild. The public exploits focus on leaking the victim’s MySQL database credentials – an unexciting prospect (we thought), because exposing the database to the internet is a dangerous misconfiguration. Nonetheless, attackers seemed interested in the vulnerability, so we sought to find out why. --------------------------------------------- https://vulncheck.com/blog/joomla-for-rce ∗∗∗ Fehlalarm: Microsoft-Defender-Warnung vor deaktiviertem Schutz führt in die Irre ∗∗∗ --------------------------------------------- Unter Windows 11 zeigt Microsoft Defender auf vielen Systemen einen deaktivieren Schutz durch "die lokalen Sicherheitsautorität".

We also observed that the threat actors were actively changing their tools, tactics, and procedures (TTPs) to bypass security solutions. In this blog entry, we will introduce and analyze the other tools and malware used by the threat actor. --------------------------------------------- https://www.trendmicro.com/en_us/research/23/c/earth-preta-updated-stealthy… ===================== = Vulnerabilities = ===================== ∗∗∗ Virenschutz: Malwarebytes ermöglicht Rechteausweitung ∗∗∗ --------------------------------------------- Der Virenschutz von Malwarebytes ermöglicht Angreifern, beliebige Dateien zu löschen oder ihre Rechte im System auszuweiten.

===================== = End-of-Day report = ===================== Timeframe: Dienstag 14-03-2023 18:00 − Mittwoch 15-03-2023 18:00 Handler: Michael Schlagenhaufer Co-Handler: Stephan Richter ===================== = News = ===================== ∗∗∗ IPFS phishing and the need for correctly set HTTP security headers, (Wed, Mar 15th) ∗∗∗ --------------------------------------------- In the last couple of weeks, Ive noticed a small spike in the number of phishing messages that carried links to fake HTML login pages hosted on the InterPlanetary File System (IPFS)- an interesting web-based decentralized/peer-to-peer data storage system. Unfortunately, pretty much any type of internet-connected data storage solution is used to host malicious content by threat actors these days, and the IPFS is no exception. --------------------------------------------- https://isc.sans.edu/diary/rss/29638 ∗∗∗ How to Find & Fix: WordPress Pharma Hack ∗∗∗ --------------------------------------------- Finding bogus content and unexpected links for prescription drugs on your WordPress website can be a frustrating experience. But don’t blame your site: it just got caught up in a bad crowd of black hat SEO spammers and fell victim to a pharma hack. Pharma spam occurs when bad actors inject a website with keywords for pharmaceutical products. Their end goal is to use an innocent site’s good reputation to lure traffic to a scam. --------------------------------------------- https://blog.sucuri.net/2023/03/find-fix-wordpress-pharma-hack.html ∗∗∗ New Cryptojacking Operation Targeting Kubernetes Clusters for Dero Mining ∗∗∗ --------------------------------------------- Cybersecurity researchers have discovered the first-ever illicit cryptocurrency mining campaign used to mint Dero since the start of February 2023. "The novel Dero cryptojacking operation concentrates on locating Kubernetes clusters with anonymous access enabled on a Kubernetes API and listening on non-standard ports accessible from the internet," CrowdStrike said in a new report [...] --------------------------------------------- https://thehackernews.com/2023/03/new-cryptojacking-operation-targeting.html ∗∗∗ Exploiting CVE-2023-23397: Microsoft Outlook Elevation of Privilege Vulnerability ∗∗∗ --------------------------------------------- At MDSec, we’re continually looking to weaponise both private and public vulnerabilities to assist us during our red team operations. Having recently given a talk on leveraging NTLM relaying during red team engagements at FiestaCon, this vulnerability particularly stood out to me and warranted further analysis. --------------------------------------------- https://www.mdsec.co.uk/2023/03/exploiting-cve-2023-23397-microsoft-outlook… ∗∗∗ Apple räumt ein: iOS-Dienste können VPN-Tunnel umgehen ∗∗∗ --------------------------------------------- iOS schleust bestimmten Datenverkehr an einer aktiven VPN-Verbindung vorbei, warnen Sicherheitsforscher seit Längerem. Das ist laut Apple so gewollt. --------------------------------------------- https://heise.de/-7545702 ∗∗∗ Patchday: Microsoft dichtet aktiv angegriffene Sicherheitslücken ab ∗∗∗ --------------------------------------------- Neben zwei aktiv missbrauchten Sicherheitslücken liefert Microsoft zum März-Patchday Aktualisierungen für zahlreiche Produkte. Sie schließen zig Schwachstellen. --------------------------------------------- https://heise.de/-7545903 ∗∗∗ Gefälschtes SMS von DHL stiehlt Ihre Kreditkartendaten ∗∗∗ --------------------------------------------- In der betrügerischen DHL-Nachricht steht, dass Ihr Paket Lieferprobleme hat. Das Problem kann gelöst werden, indem Sie auf den Link klicken. Klicken Sie nicht auf den Link. Sie werden auf eine nachgebaute DHL-Website gelockt, wo persönliche Infos und Kreditkartendaten abgefragt werden. In weiterer Folge wird Ihre Kreditkarte auf einem fremden Gerät für Apple Pay aktiviert. --------------------------------------------- https://www.watchlist-internet.at/news/gefaelschtes-sms-von-dhl-stiehlt-ihr… ∗∗∗ Uncovering Windows Events ∗∗∗ --------------------------------------------- Not all manifest-based Event Tracing for Windows (ETW) providers that are exposed through Windows are ingested into telemetry sensors/EDR’s. One provider commonly that is leveraged by vendors is the Threat-Intelligence ETW provider. Due to how often it is used, I wanted to map out how its events are being written within TelemetrySource. This post will focus on the process I followed to understand the events the Threat-Intelligence ETW provider logs and how to uncover the underlying mechanisms. One can use a similar process when trying to reverse other manifest-based ETW providers. This post isn’t a deep dive into how ETW works, [...] --------------------------------------------- https://posts.specterops.io/uncovering-windows-events-b4b9db7eac54?source=r… ∗∗∗ Released: March 2023 Exchange Server Security Updates ∗∗∗ --------------------------------------------- Microsoft has released Security Updates (SUs) for vulnerabilities found in: Exchange Server 2013 Exchange Server 2016 Exchange Server 2019 --------------------------------------------- https://techcommunity.microsoft.com/t5/exchange-team-blog/released-march-20… ∗∗∗ How does malware spread?

It’s a great vuln, in theory allowing code execution over ICMP. It also sounds really scary, as it’s a high CVSS score in Windows OS on a commonly used protocol. --------------------------------------------- https://doublepulsar.com/a-look-at-cve-2023-23415-a-windows-icmp-vulnerabil… ===================== = Vulnerabilities = ===================== ∗∗∗ Patchday: Adobe schließt Zero-Day-Lücke und mehr als 100 Schwachstellen ∗∗∗ --------------------------------------------- Adobe dichtet am März-Patchday 106 Sicherheitslecks ab. Eine davon in Adobe ColdFusion missbrauchen Cyberkriminelle bereits in Angriffen. --------------------------------------------- https://heise.de/-7546150 ∗∗∗ Security updates for Wednesday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (node-sqlite3 and qemu), Fedora (libmemcached-awesome, manifest-tool, sudo, and vim), Red Hat (gnutls, kernel, kernel-rt, lua, and openssl), Slackware (mozilla), SUSE (amanda, firefox, go1.19, go1.20, jakarta-commons-fileupload, java-1_8_0-openjdk, nodejs18, peazip, perl-Net-Server, python, python-cryptography, python-Django, python3, rubygem-rack, and xorg-x11-server), and Ubuntu (ipython, linux-ibm, linux-ibm-5.4, and linux-kvm). --------------------------------------------- https://lwn.net/Articles/926205/ ∗∗∗ SAP-Patchday enthält Updates für kritische Sicherheitslücken ∗∗∗ --------------------------------------------- Der aktuelle Patchday von SAP beinhaltet mehrere Schwachstellen mit einem CVSS-Score >9.0. Insbesondere eine kritische Sicherheitslücke in SAP NetWeaver AS for Java (CVE-2023-23857) ist trivial ausnutzbar; sie erlaubt Angreifer:innen aufgrund unzureichender Authentifizierungsprüfungen weitreichenden Systemzugriff ohne jegliche Form von Authentifizierung.

According to Fortinet FortiGuard Labs, the attack chain commences with the successful exploitation of susceptible Oracle WebLogic servers to download a PowerShell script that contains ScrubCrypt. --------------------------------------------- https://thehackernews.com/2023/03/new-scrubcrypt-crypter-used-in.html ∗∗∗ EJS - Server Side Prototype Pollution gadgets to RCE ∗∗∗ --------------------------------------------- Last month (February 2023), I took a look into NodeJS HTML templating libraries. During my research, I found an interesting Server Side Prototype Pollution (SSPP) gadget in the EJS library which can be leveraged to RCE. After finding this issue, I spent a week searching for an SSPP in express core or dependencies, but I didnt find any issue. Thats why, after reporting this issue to the repository maintainer, Im making an article to explain technical details. --------------------------------------------- https://mizu.re/post/ejs-server-side-prototype-pollution-gadgets-to-rce ∗∗∗ How to Avoid LDAP Injection Attacks ∗∗∗ --------------------------------------------- The key vulnerability that puts an application at risk of LDAP injection is improperly processed user input.

The vulnerabilities could allow attackers to execute code remotely in order to activate and control the device’s camera and microphone, steal video and images, or gain a network foothold. --------------------------------------------- https://claroty.com/team82/research/the-silent-spy-among-us-modern-attacks-… ∗∗∗ Multi-Technology Script Leading to Browser Hijacking ∗∗∗ --------------------------------------------- [..] in the real world, malware samples use multiple technologies to perform malicious actions. I spotted a VBScript file (I don’t know where it’s coming from, probably a phishing campaign). The script has been flagged by only one(!) AV product on VT --------------------------------------------- https://isc.sans.edu/diary/rss/29620 ∗∗∗ The oldest privesc: injecting careless administrators terminals using TTY pushback ∗∗∗ --------------------------------------------- This trick is possibly the oldest security bug that still exists today, it’s been traced as far back as 1985. It’s been discovered and rediscovered and re-rediscovered by sysadmins, developpers and pentesters every few years for close to 4 decades now. It’s been subject to multiple developper battles, countless posts, but still remains largely forgotten. This is just another attempt at shedding light on it, for both attackers and defenders. --------------------------------------------- https://www.errno.fr/TTYPushback.html ∗∗∗ When Partial Protection is Zero Protection: The MFA Blind Spots No One Talks About ∗∗∗ --------------------------------------------- Multi-factor Authentication (MFA) has long ago become a standard security practice. [..] While compatible with RDP connection and local desktop logins, they offer no protection to remote command line access tools like PsExec, Remote PowerShell and their likes. [..] In this article well explore this blind spot, understand its root cause and implications, and view the different options security teams can overcome it to maintain their environments protected. --------------------------------------------- https://thehackernews.com/2023/03/when-partial-protection-is-zero.html ∗∗∗ Leveraging ssh-keygen for Arbitrary Execution (and Privilege Escalation) ∗∗∗ --------------------------------------------- The ssh-keygen command can be used to load a shared library with the -D flag. This can be useful for privilege escalation (described in this blog post), or to translate to arbitrary code execution from argument injection, file overwrites, etc. --------------------------------------------- https://seanpesce.blogspot.com/2023/03/leveraging-ssh-keygen-for-arbitrary.… ∗∗∗ Unauthorized access to Codespace secrets in GitHub ∗∗∗ --------------------------------------------- We identified a security issue in GitHub’s Repository Security Advisory feature (https://docs.github.com/en/code-security/security-advisories/repository-sec…) that allowed us to retrieve plaintext Codespace secrets of any organization including GitHub. --------------------------------------------- https://ophionsecurity.com/blog/access-organization-secrets-in-github ∗∗∗ Pirated copies of Final Cut Pro infect Macs with cryptojacking malware ∗∗∗ --------------------------------------------- Torrents on The Pirate Bay which claim to contain Final Cut Pro are instead being used to distribute malware, designed to infect your Mac with cryptojacking malware. --------------------------------------------- https://grahamcluley.com/pirated-copies-of-final-cut-pro-infect-macs-with-c… ∗∗∗ GoBruteforcer: Golang-Based Botnet Actively Harvests Web Servers ∗∗∗ --------------------------------------------- New Golang-based malware we have dubbed GoBruteforcer targets web servers. Golang is becoming popular with malware programmers due to its versatility. --------------------------------------------- https://unit42.paloaltonetworks.com/gobruteforcer-golang-botnet/ ∗∗∗ Netcat Attack Cases Targeting MS-SQL Servers (LOLBins) ∗∗∗ --------------------------------------------- ASEC (AhnLab Security Emergency response Center) has recently discovered the distribution of the Netcat malware targeting poorly managed MS-SQL servers. Netcat is a utility that allows users to send and receive data from specific destinations on a network connected by the TCP/UDP protocol. Due to its various features and ability to be used on both Linux and Windows, it is utilized by network managers and threat actors alike. --------------------------------------------- https://asec.ahnlab.com/en/49249/ ∗∗∗ Everything You Didn’t Know About Cross-Account and Cross-Cloud Provider Attacks ∗∗∗ --------------------------------------------- Wait, did you say ‘Cross-Cloud Provider Attacks’? Yes, this is actually a growing type of attack path: As organizations increasingly adopt multiple cloud platforms, their lack of security visibility across the clouds makes them a sitting target for these types of attacks. --------------------------------------------- https://orca.security/resources/blog/cross-account-cross-provider-attack-pa… ∗∗∗ Suspected Chinese Campaign to Persist on SonicWall Devices, Highlights Importance of Monitoring Edge Devices ∗∗∗ --------------------------------------------- Mandiant, working in partnership with SonicWall Product Security and Incident Response Team (PSIRT), has identified a suspected Chinese campaign that involves maintaining long term persistence by running malware on an unpatched SonicWall Secure Mobile Access (SMA) appliance. The malware has functionality to steal user credentials, provide shell access, and persist through firmware upgrades. --------------------------------------------- https://www.mandiant.com/resources/blog/suspected-chinese-persist-sonicwall ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Friday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (chromium and wireless-regdb), Fedora (caddy, python-cryptography, and redis), Oracle (gnutls), SUSE (hdf5, opera, python-Django, redis, tomcat, and xen), and Ubuntu (apache2 and snakeyaml). --------------------------------------------- https://lwn.net/Articles/925840/ ∗∗∗ IBM Security Bulletins 2023-03-10 ∗∗∗ --------------------------------------------- * Apache Commons Beanutils (Publicly disclosed vulnerability) affects IBM eDiscovery Manager (CVE-2019-10086, CVE-2014-0114) * Apache Commons FileUpload (Publicly disclosed vulnerability) affects IBM eDiscovery Manager (CVE-2023-24998) * Apache Commons IO (Publicly disclosed vulnerability) Affects IBM eDiscovery Manager (CVE-2021-29425) * IBM MQ is affected by a vulnerability in Apache Commons Net (CVE-2021-37533) * IBM QRadar WinCollect agent has multiple vulnerabilities * IBM QRadar Wincollect agent is vulnerable to server side request forgery (SSRF) (CVE-2022-43879) * IBM SDK, Java Technology Edition, Security Update February 2023 * multiple vulnerabilities in Java SE may affect CICS TX Advanced * multiple vulnerabilities in Java SE may affect CICS TX Standard * multiple vulnerabilities in Java SE may affect TXSeries for Multiplatforms * server-side request forgery vulnerability in Apache CXF (CVE-2022-46364) may affect CICS TX Advanced * server-side request forgery vulnerability in Apache CXF (CVE-2022-46364) may affect CICS TX Standard * server-side request forgery vulnerability in Apache CXF (CVE-2022-46364) may affect TXSeries for Multiplatforms * vulnerability in Apache James MIME4J (CVE-2022-45787) may affect CICS TX Advanced * vulnerability in Apache James MIME4J (CVE-2022-45787) may affect CICS TX Standard * vulnerability in Apache James MIME4J (CVE-2022-45787) may affect TXSeries for Multiplatforms * Watson CP4D Data Stores is vulnerable to jackson-databind due to FasterXML jackson-databind before 2.14.0-rc1 ( CVE-2022-42003 ) --------------------------------------------- https://www.ibm.com/support/pages/bulletin/ ∗∗∗ [R1] Nessus Agent Version 10.3.2 Fixes Multiple Vulnerabilities ∗∗∗ --------------------------------------------- https://www.tenable.com/security/tns-2023-12 ∗∗∗ [R1] Nessus Agent Version 8.3.5 Fixes Multiple Vulnerabilities ∗∗∗ --------------------------------------------- https://www.tenable.com/security/tns-2023-13 -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily
