===================== = End-of-Day report = ===================== Timeframe: Montag 14-11-2022 18:00 − Dienstag 15-11-2022 18:00 Handler: Thomas Pribitzer Co-Handler: Robert Waldner ===================== = News = ===================== ∗∗∗ DTrack activity targeting Europe and Latin America ∗∗∗ --------------------------------------------- DTrack is a backdoor used by the Lazarus group. Initially discovered in 2019, the backdoor remains in use three years later. It is used by the Lazarus group against a wide variety of targets. [..] So, what’s new? DTrack itself hasn’t changed much over the course of time. Nevertheless, there are some interesting modifications that we want to highlight in this blogpost. Dtrack hides itself inside an executable that looks like a legitimate program, and there are several stages of decryption before the malware payload starts. --------------------------------------------- https://securelist.com/dtrack-targeting-europe-latin-america/107798/ ∗∗∗ ABI compatibility in Python: How hard could it be? ∗∗∗ --------------------------------------------- This post will cover just one tiny piece of Python packaging’s complexity: the CPython stable ABI. We’ll see what the stable ABI is, why it exists, how it’s integrated into Python packaging, and how each piece goes terribly wrong to make accidental ABI violations easy. --------------------------------------------- https://blog.trailofbits.com/2022/11/15/python-wheels-abi-abi3audit/ ∗∗∗ Checkmk: Remote Code Execution by Chaining Multiple Bugs ∗∗∗ --------------------------------------------- Within the series of articles, we take a detailed look at multiple vulnerabilities we identified in Checkmk and its NagVis integration, which can be chained together by an unauthenticated, remote attacker to fully take over the server running a vulnerable version of Checkmk. --------------------------------------------- https://blog.sonarsource.com/checkmk-rce-chain-3/ ∗∗∗ Organizations Warned of Critical Vulnerability in Backstage Developer Portal Platform ∗∗∗ --------------------------------------------- Backstage is affected by a critical vulnerability related to a security hole found earlier this year by Oxeye in the popular sandbox library VM2. The VM2 flaw, dubbed SandBreak and tracked as CVE-2022-36067, can allow a remote attacker to escape the sandbox and execute arbitrary code on the host. Backstage has been using VM2 and Oxeye researchers discovered that CVE-2022-36067 can be exploited for unauthenticated remote code execution in Backstage by abusing its software templates. --------------------------------------------- https://www.securityweek.com/organizations-warned-critical-vulnerability-ba… ∗∗∗ Kreditbetrug: Vorsicht vor darlehenexpert.com ∗∗∗ --------------------------------------------- darlehenexpert.com gibt sich als Kreditgeber aus und ermöglicht angeblich Privat- und Autokredite, Hypotheken sowie Darlehen.

The developer is now banned from Google Play - but if youve not uninstalled the apps, youre still infected. [..] The four apps that have been identified as malicious were from a developer called Mobile apps Group and were called 'Bluetooth Auto Connect', 'Bluetooth App Sender', 'Mobile transfer: smart switch', and 'Driver: Bluetooth, Wi-Fi, USB'. --------------------------------------------- https://www.zdnet.com/article/android-warning-these-malicious-apps-had-over… ∗∗∗ Windows Server 2012 R2: Sophos User-Authentifizierung mittels Heartbeat auf RDS-Servern abgeschaltet ∗∗∗ --------------------------------------------- Kurzer Hinweis für Administratoren, die Windows Server 2012 R2 einsetzen und sich auf die Sophos User-Authentifizierung per Sophos Security Heartbeats verlassen. Sophos hat ein Update verteilt, welches die Funktion auf Windows Server 2012 R2 stillschweigend außer Kraft setzt. --------------------------------------------- https://www.borncity.com/blog/2022/11/15/windows-server-2012-r2-sophos-user… ∗∗∗ LKA warnt vor Betrugsmasche mit digitalen Kreditkarten (Nov. 2022) ∗∗∗ --------------------------------------------- Das LKA Niedersachsen warnt vor einer neue Betrugsmasche, die Cyber-Kriminelle erdacht haben. Mittels Phishing-E-Mails, gefälschten Webseiten und digitalen Kreditkarten versuchen sie an Zahlungsdaten der Opfer heranzukommen. Die Daten der digitalen Kreditkarte werden dann für eigene Einkäufe auf Kosten des Opfers missbraucht. --------------------------------------------- https://www.borncity.com/blog/2022/11/15/lka-warnt-vor-betrugsmasche-mit-di… ∗∗∗ Firmware- und BIOS-Updates: AMD, Intel, Lenovo, HP (Nov. 2022) ∗∗∗ --------------------------------------------- Die Hersteller Lenovo und HP stopfen mit Firmware-Updates entdeckte Schwachstellen im BIOS (und in der Software) ihrer Systeme.

They were fixed as CVE-2021-25337, CVE-2021-25369, CVE-2021-25370. To ensure your Samsung device is up-to-date under settings you can check that your device is running SMR Mar-2021 or later. As defenders, in-the-wild exploit samples give us important insight into what attackers are really doing. We get the “ground truth” data about the vulnerabilities and exploit techniques they’re using, which then informs our further research and guidance to security teams on what could have the biggest impact or return on investment. To do this, we need to know that the vulnerabilities and exploit samples were found in-the-wild. --------------------------------------------- https://googleprojectzero.blogspot.com/2022/11/a-very-powerful-clipboard-sa… ∗∗∗ What Is Cross-Origin Resource Sharing (CORS)? ∗∗∗ --------------------------------------------- Thanks to the rapid growth of JavaScript frameworks like Angular, React, and Vue, Cross-Origin Resource Sharing (CORS) has become a popular word in the developer’s vocabulary — and for good reason.

In this post, we’ll take a look at what CORS is and why proper implementation is an important component of building secure websites and applications. We’ll also examine some common examples of how to use CORS, dive into preflight requests, and discuss how to protect your website against attacks. --------------------------------------------- https://blog.sucuri.net/2022/11/what-is-cross-origin-resource-sharing-cors.… ∗∗∗ Multi-factor auth fatigue is real – and its why you may be in the headlines next ∗∗∗ --------------------------------------------- Overwhelmed by waves of push notifications, worn-down users inadvertently let the bad guys in Analysis The September cyberattack on ride-hailing service Uber began when a criminal bought the stolen credentials of a company contractor on the dark web. --------------------------------------------- https://go.theregister.com/feed/www.theregister.com/2022/11/03/mfa_fatigue_… ∗∗∗ Inside the V1 Raccoon Stealer’s Den ∗∗∗ --------------------------------------------- Team Cymru’s S2 Research Team has blogged previously on the initial Raccoon stealer command and control methodology (Raccoon Stealer - An Insight into Victim “Gates”), which utilized “gate” IP addresses to proxy victim traffic / data to static threat actor-controlled infrastructure.

Sie werden aufgefordert, auf einen Link zu klicken, um zusätzlichen Speicherplatz freizuschalten. Klicken Sie nicht auf den Link, Sie landen auf einer manipulierten Login-Seite. --------------------------------------------- https://www.watchlist-internet.at/news/gefaelschtes-a1-mail-im-umlauf/ ∗∗∗ 2022 OpenSSL vulnerability ∗∗∗ --------------------------------------------- This repo contains operational information regarding the recently announced vulnerability in OpenSSL 3. [...] 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 was obvious that such a library could be prone to Server-Side Request Forgery (SSRF) issues (e.g., loading of images from remote resources). --------------------------------------------- https://www.thezdi.com/blog/2022/10/28/vulnerabilities-in-apache-batik-defa… ∗∗∗ AgentTesla Being Distributed via VBS ∗∗∗ --------------------------------------------- The ASEC analysis team has recently identified that AgentTesla is being distributed through malicious VBS. The script file has multiple codes that have been obfuscated multiple times. AgentTesla has been found to be distributed last May through a Windows Help file (*.chm), and it seems that its distribution method is continuously changing. --------------------------------------------- https://asec.ahnlab.com/en/40890/ ===================== = Vulnerabilities = ===================== ∗∗∗ IBM Security Bulletins ∗∗∗ --------------------------------------------- App Connect Professional, IBM Business Automation Manager Open Editions 8.0.1, IBM CICS TX Advanced, IBM CICS TX Standard, IBM Cloud Pak for Business Automation, IBM Cloud Pak for Security, IBM Event Streams, IBM Host Access Transformation Services, IBM MQ Appliance --------------------------------------------- https://www.ibm.com/blogs/psirt/ ∗∗∗ CVE-2022-31690: Privilege Escalation in spring-security-oauth2-client ∗∗∗ --------------------------------------------- Spring Security 5.6.9 and 5.7.5 released on October 31st, 2022 included a fix for CVE-2022-31690 affecting the mapping of authorized scopes in spring-security-oauth2-client.

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).

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.

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.

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.

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.

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.
