[...] Currently no complete overview of vulnerable products is available. Please see https://github.com/NCSC-NL/OpenSSL-2022/blob/main/software/README.md for a list of products that are known to be vulnerable. The list is a work in progress. --------------------------------------------- https://github.com/NCSC-NL/OpenSSL-2022 ∗∗∗ Upcoming Critical OpenSSL Vulnerability: What will be Affected?, (Thu, Oct 27th) ∗∗∗ --------------------------------------------- Some here may still remember Heartbleed. Heartbleed was a critical OpenSSL vulnerability that surprised many organizations, and patching the issue was a major undertaking. Heartbleed caused OpenSSL and other open-source projects to rethink how they address security issues and communicate with their users. OpenSSL started to pre-announce any security updates about a week ahead of time. This week, OpenSSL announced they would release OpenSSL 3.0.7 this coming Tuesday. It will fix a critical vulnerability [1]. --------------------------------------------- https://isc.sans.edu/diary/rss/29192 ∗∗∗ APT10: Tracking down LODEINFO 2022, part I ∗∗∗ --------------------------------------------- The first part of this report will provide technical analysis of the new infection methods such as SFX files and DOWNIISSA, a new downloader shellcode used to deploy the LODEINFO backdoor. --------------------------------------------- https://securelist.com/apt10-tracking-down-lodeinfo-2022-part-i/107742/ ∗∗∗ APT10: Tracking down LODEINFO 2022, part II ∗∗∗ --------------------------------------------- In the second part of this report, we discuss improvements made to the LODEINFO backdoor shellcode in 2022. --------------------------------------------- https://securelist.com/apt10-tracking-down-lodeinfo-2022-part-ii/107745/ ∗∗∗ NMAP without NMAP - Port Testing and Scanning with PowerShell, (Mon, Oct 31st) ∗∗∗ --------------------------------------------- Ever needed to do a portscan and didn't have nmap installed? I've had this more than once on an internal pentest or more often just on run-rate "is that port open? / is there a host firewall in the way?" testing. --------------------------------------------- https://isc.sans.edu/diary/rss/29202 ∗∗∗ WordPress Vulnerability & Patch Roundup October 2022 ∗∗∗ --------------------------------------------- [...] To help educate website owners on emerging threats to their environments, we’ve compiled a list of important security updates and vulnerability patches for the WordPress ecosystem this past month. --------------------------------------------- https://blog.sucuri.net/2022/10/wordpress-vulnerability-patch-roundup-octob… ∗∗∗ Hardware Trojans Under a Microscope ∗∗∗ --------------------------------------------- While the security industry generally focuses on software cyber attacks, we can’t forget the security impact of lower level hardware flaws, such as those that affect semiconductors. --------------------------------------------- https://ryancor.medium.com/hardware-trojans-under-a-microscope-bf542acbcc29 ∗∗∗ What I learnt from reading 217* Subdomain Takeover bug reports. ∗∗∗ --------------------------------------------- My two prior blogs, What I Learnt From Reading 220 IDOR bug reports, and What I Learnt From Reading 126 Information Disclosure Writeups*, were well received, so I’m continuing the series. I once more scraped ALL 143 SDTO bug reports from hackerone, and 74 detailed write-ups, then went into hiding as I read and took notes on them. I’m here to show you my actionable findings, and show you how to properly hunt for SDTOs. --------------------------------------------- https://medium.com/@nynan/what-i-learnt-from-reading-217-subdomain-takeover… ∗∗∗ Free Micropatches For Bypassing MotW Security Warning with Invalid Signature (0day) ∗∗∗ --------------------------------------------- Nine days ago we issued micropatches for a vulnerability that allows attackers to bypass the warning Windows normally present to users when they try to open a document or executable obtained from an untrusted source (Internet, email, USB key, network drive). That vulnerability, affecting all supported and many legacy Windows versions, still has no official patch from Microsoft so our (free!) patches are the only actual patches in existence as of this writing. On the very same day we issued these micropatches, Will Dormann - who researched said vulnerability - replied to a tweet by another security researcher, Patrick Schläpfer. Patrick works at HP Wolf Security where they analyzed the Magniber Ransomware and wrote a detailed analysis of its working. Will asked Patrick about the ZIP files used in the malware campaign to see if they were exploiting the same vulnerability or employing some other trick to bypass the "Mark of the Web". [...] And so a new 0day - already exploited in the wild - was revealed. --------------------------------------------- https://blog.0patch.com/2022/10/free-micropatches-for-bypassing-motw.html ∗∗∗ The Defender’s Guide to the Windows Registry ∗∗∗ --------------------------------------------- Welcome to the Defender’s Guide. This is a series of blog posts designed to give you a ground-up start to defending a specific technology from potential attackers. While a lot of this information may be redundant to a more seasoned information security personnel, even the best of us rely on Google and blog posts to get information. These posts are designed to be a one-stop shop, bringing a lot of that information together. --------------------------------------------- https://posts.specterops.io/the-defenders-guide-to-the-windows-registry-feb… ∗∗∗ Banking Trojan Techniques: How Financially Motivated Malware Became Infrastructure ∗∗∗ --------------------------------------------- Learning about the variety of techniques used by banking Trojans can help us detect other activities of financially motivated threat groups. --------------------------------------------- https://unit42.paloaltonetworks.com/banking-trojan-techniques/ ∗∗∗ Follina Exploit Leads to Domain Compromise ∗∗∗ --------------------------------------------- In early June 2022, we observed an intrusion where a threat actor gained initial access by exploiting the CVE-2022-30190 (Follina) vulnerability which triggered a Qbot infection chain. --------------------------------------------- https://thedfirreport.com/2022/10/31/follina-exploit-leads-to-domain-compro… ∗∗∗ Vulnerabilities in Apache Batik Default Security Controls – SSRF and RCE Through Remote Class Loading ∗∗∗ --------------------------------------------- I stumbled upon the Apache Batik library while researching other Java-based products. It immediately caught my attention, as this library parses Scalable Vector Graphics (SVG) files and transforms them into different raster graphics formats (i.e., PNG, PDF, or JPEG). I was even more encouraged when I looked at the Batik documentation.

It is "part of a complex and interconnected malware ecosystem, with links to other malware families and alternate infection methods beyond its original USB drive spread," the Microsoft Security Threat Intelligence Center (MSTIC) said in a detailed write-up. --------------------------------------------- https://thehackernews.com/2022/10/raspberry-robin-operators-selling.html ∗∗∗ TCP/IP Vulnerability CVE-2022–34718 PoC Restoration and Analysis ∗∗∗ --------------------------------------------- The patch released by Microsoft last month contained a vulnerability in the TCP/IP protocol that allowed for code execution.

To the point that my tool rtfdump.py and Philippe's tool rtfobj don't find embedded objects. --------------------------------------------- https://isc.sans.edu/diary/rss/29174 ∗∗∗ C2 Communications Through outlook.com, (Mon, Oct 24th) ∗∗∗ --------------------------------------------- Most malware implements communication with their C2 server over HTTP(S). Why? Just because it works! But they are multiple ways to implement C2 communications: DNS, P2P, Layer 7 (Twitter), ... Another one that has become less popular with time is SMTP (email communications). I spotted a malicious Python script that exchanges information with its C2 server through emails. --------------------------------------------- https://isc.sans.edu/diary/rss/29180 ∗∗∗ SCuBA M365 Security Baseline Assessment Tool ∗∗∗ --------------------------------------------- Developed by CISA, this assessment tool verifies that an M365 tenant’s configuration conforms to the policies described in the SCuBA Minimum Viable Secure Configuration Baseline documents. --------------------------------------------- https://github.com/cisagov/ScubaGear ∗∗∗ Cisco ISE: Angreifer könnten Kontrolle übernehmen ∗∗∗ --------------------------------------------- Cisco warnt, dass Angreifer Dateien in der Identity Services Engine lesen und löschen könnten.

This injected script causes a fake browser update page to appear in the victim's browser. The fake browser update page presents the malware payload for download. More information on the campaign can be found here. In previous weeks, this campaign pushed SolarMarker malware. I ran across one such example on 2022-09-27. This month, we've started seeing a payload for NetSupport RAT from the sczriptzzbn inject. --------------------------------------------- https://isc.sans.edu/diary/rss/29170 ∗∗∗ Archive Sidestepping: Emotet Botnet Pushing Self-Unlocking Password-Protected RAR ∗∗∗ --------------------------------------------- Trustwave SpiderLabs’ spam traps have identified an increase in threats packaged in password-protected archives with about 96% of these being spammed by the Emotet Botnet. In the first half of 2022, we identified password-protected ZIP files as the third most popular archive format used by cybercriminals to conceal malware. --------------------------------------------- https://www.trustwave.com/en-us/resources/blogs/spiderlabs-blog/archive-sid… ∗∗∗ Wordfence Evasion Malware Conceals Backdoors ∗∗∗ --------------------------------------------- Malware authors, with some notable exceptions, tend to design their malicious code to hide from sight. The techniques they use help their malware stay on the victim’s website for as long as possible and ensure execution. For example — obfuscation techniques, fake code comments, naming conventions for injections that deploy SEO spam, redirect visitors to malicious third party websites, or steal credit card information from eCommerce stores. --------------------------------------------- https://blog.sucuri.net/2022/10/wordfence-evasion-malware-conceals-backdoor… ∗∗∗ Multiple Campaigns Exploit VMware Vulnerability to Deploy Crypto Miners and Ransomware ∗∗∗ --------------------------------------------- A now-patched vulnerability in VMware Workspace ONE Access has been observed being exploited to deliver both cryptocurrency miners and ransomware on affected machines. "The attacker intends to utilize a victims resources as much as possible, not only to install RAR1Ransom for extortion, but also to spread GuardMiner to collect cryptocurrency," Fortinet FortiGuard Labs researcher Cara Lin said in a Thursday report. --------------------------------------------- https://thehackernews.com/2022/10/multiple-campaigns-exploit-vmware.html ∗∗∗ Threat Advisory: Monitoring CVE-2022-42889 “Text4Shell” Exploit Attempts ∗∗∗ --------------------------------------------- On October 17, 2022, the Wordfence Threat Intelligence team began monitoring for activity targeting CVE-2022-42889, or “Text4Shell” on our network of 4 million websites. We started seeing activity targeting this vulnerability on October 18, 2022.

The malware that is installed include infostealers which steal information from the infected system, ransomware which encrypts files to demand ransom, and DDoS Bots which are used in DDoS attacks. In addition to these, backdoor and RAT are also major programs used by attackers. --------------------------------------------- https://asec.ahnlab.com/en/40263/ ===================== = Vulnerabilities = ===================== ∗∗∗ IBM Security Bulletins 2022-10-20 ∗∗∗ --------------------------------------------- IBM Security Verify Gateway/Bridge, IBM Enterprise Records, IBM Sterling Order Management Netty, IBM WebSphere Application Server, IBM MQ Operator, IBM Sterling Order Management, IBM Enterprise Records, IBM Netezza Host Management. --------------------------------------------- https://www.ibm.com/blogs/psirt/ ∗∗∗ SolarWinds Security Advisories 2022-10-19 ∗∗∗ --------------------------------------------- SolarWinds released 4 new Security Advisories (3 high, 1 medium) for SolarWinds Platform 2022.4 RC1. --------------------------------------------- https://www.solarwinds.com/trust-center/security-advisories ∗∗∗ SSA-640732 V1.0: Authentication Bypass Vulnerability in Siveillance Video Mobile Server ∗∗∗ --------------------------------------------- The mobile server component of Siveillance Video 2022 R2 contains an authentication bypass vulnerability that could allow an unauthenticated remote attacker to access the application without a valid account.Siemens has released a hotfix for Siveillance Video 2022 R2 and recommends to apply the hotfix on all installations of the mobile server. --------------------------------------------- https://cert-portal.siemens.com/productcert/txt/ssa-640732.txt ∗∗∗ Security updates for Friday ∗∗∗ --------------------------------------------- Security updates have been issued by Fedora (poppler), Oracle (firefox and thunderbird), Red Hat (firefox, java-1.8.0-openjdk, java-11-openjdk, and java-17-openjdk), SUSE (bind, clone-master-clean-up, grafana, libksba, python3, tiff, and v4l2loopback), and Ubuntu (libreoffice). --------------------------------------------- https://lwn.net/Articles/911989/ -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

===================== = End-of-Day report = ===================== Timeframe: Montag 17-10-2022 18:00 − Dienstag 18-10-2022 18:00 Handler: Stephan Richter Co-Handler: n/a ===================== = News = ===================== ∗∗∗ CVE-2022-42889: Keep Calm and Stop Saying "4Shell" ∗∗∗ --------------------------------------------- [...] The vulnerability has been compared to Log4Shell since it is an open-source library-level vulnerability that is likely to impact a wide variety of software applications that use the relevant object. However, initial analysis indicates that this is a bad comparison. The nature of the vulnerability means that unlike Log4Shell, it will be rare that an application uses the vulnerable component of Commons Text to process untrusted, potentially malicious input. In summary, much like with Spring4Shell, there are significant caveats to practical exploitability for CVE-2022-42889. With that said, we still recommend patching any relevant impacted software according to your normal, hair-not-on-fire patch cycle. --------------------------------------------- https://www.rapid7.com/blog/post/2022/10/17/cve-2022-42889-keep-calm-and-st… ∗∗∗ Europol: Festgenommene Autodiebe stahlen Fahrzeuge mittels Software ∗∗∗ --------------------------------------------- In Frankreich wurden 31 Mitglieder einer Diebesbande festgenommen, die Autos mit schlüssellosen Zugangssystemen per Software gestohlen haben sollen. --------------------------------------------- https://www.golem.de/news/europol-festgenommene-autodiebe-stahlen-fahrzeuge… ∗∗∗ Sicherheit: Antivirensoftware blockiert Thunderbird-Updates ∗∗∗ --------------------------------------------- Statt für Sicherheit zu sorgen, blockieren Avast und AVG Thunderbird-Updates.

Rapid7 investigated these issues to better understand their impact, and found that the patch is not sufficient to prevent exploitation. We also determined that the worst outcome of this vulnerability is a denial of service - the licensing server can be told to shut down (even with the patch). --------------------------------------------- https://www.rapid7.com/blog/post/2022/10/18/flexlm-and-citrix-adm-denial-of… ∗∗∗ Python Obfuscation for Dummies, (Tue, Oct 18th) ∗∗∗ --------------------------------------------- Recently, I found several malicious Python scripts that looked the same.

It’s rarely smooth sailing, and we usually encounter a hiccup or two. Fox-IT’s approach to enterprise scale incident response for the past few years has been to collect small forensic artefact packages using our internal data collection utility, “acquire”, usually deployed using the clients’ preferred method of software deployment.

===================== = End-of-Day report = ===================== Timeframe: Donnerstag 06-10-2022 18:00 − Freitag 07-10-2022 18:00 Handler: Michael Schlagenhaufer Co-Handler: Robert Waldner ===================== = News = ===================== ∗∗∗ Powershell Backdoor with DGA Capability, (Fri, Oct 7th) ∗∗∗ --------------------------------------------- DGA ("Domain Generation Algorithm") is a popular tactic used by malware to make connections with their C2 more stealthy and difficult to block. The idea is to generate domain names periodically and use them during the defined period. An alternative is to generate a lot of domains and loop across them to find an available C2 server. Attackers just register a few domain names and can change them very quickly. --------------------------------------------- https://isc.sans.edu/diary/rss/29122 ∗∗∗ What is a Malware Attack? ∗∗∗ --------------------------------------------- A malware attack is the act of injecting malicious software to infiltrate and execute unauthorized commands within a victim’s system without their knowledge or authorization. The objectives of such an attack can vary – from stealing client information to sell as lead sources, obtaining system information for personal gain, bringing a site down to stop business or even just placing the mark of a cyber-criminal on a public domain. --------------------------------------------- https://blog.sucuri.net/2022/10/what-is-a-malware-attack.html ∗∗∗ Loads of PostgreSQL systems are sitting on the internet without SSL encryption ∗∗∗ --------------------------------------------- They probably shouldnt be connected in the first place, says database expert.

Laut diversen Berichten wird diese Schwachstelle bereits aktiv ausgenutzt. Das Ausnützen der Schwachstelle durch senden einer Email mit speziell präparierten Anhängen in den Formaten .cpio, .tar, .rpm kann zu einer vollständigen Kompromittierung des Systems führen. --------------------------------------------- https://cert.at/de/warnungen/2022/10/remote-code-execution-in-zimbra-collab… ∗∗∗ Fortinet warns admins to patch critical auth bypass bug immediately ∗∗∗ --------------------------------------------- Fortinet has warned administrators to update FortiGate firewalls and FortiProxy web proxies to the latest versions, which address a critical severity vulnerability. --------------------------------------------- https://www.bleepingcomputer.com/news/security/fortinet-warns-admins-to-pat… ∗∗∗ Technical Advisory – OpenJDK – Weak Parsing Logic in java.net.InetAddress and Related Classes ∗∗∗ --------------------------------------------- An attacker may trivially bypass the use of InetAddress::getAllByName to validate inputs. Note: As input validation is not an appropriate mechanism to protect against injection attacks — as opposed to output encoding and Harvard architecture-style APIs — this issue is itself considered to be of Low risk as code relying on the documented validation for such purposes should be considered insecure regardless of this issue. --------------------------------------------- https://research.nccgroup.com/2022/10/06/technical-advisory-openjdk-weak-pa… ∗∗∗ Angreifer könnten Cisco-Admins manipulierte Updates unterschieben ∗∗∗ --------------------------------------------- Es sind wichtige Sicherheitsupdates für unter anderem Cisco Expressway Series und TelePresence Video Communication Server erschienen. --------------------------------------------- https://heise.de/-7286880 ∗∗∗ Security updates for Friday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (dbus, isc-dhcp, and strongswan), Fedora (booth, php, php-twig, php-twig2, and php-twig3), Oracle (expat, prometheus-jmx-exporter, and squid), Red Hat (expat, openvswitch2.11, and squid), Scientific Linux (expat and squid), SUSE (exiv2, LibVNCServer, postgresql-jdbc, protobuf, python-PyJWT, python3, slurm, squid, and webkit2gtk3), and Ubuntu (libreoffice). --------------------------------------------- https://lwn.net/Articles/910606/ ∗∗∗ VMware Patches Code Execution Vulnerability in vCenter Server ∗∗∗ --------------------------------------------- Virtualization giant VMware on Thursday announced patches for a vCenter Server vulnerability that could lead to arbitrary code execution. A centralized management utility, the vCenter Server is used for controlling virtual machines and ESXi hosts, along with their dependent components.
