===================== = 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.

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.

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.

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.

Angeblich hätten Sie trotz mehrerer Mahnungen eine offene Forderung gegen Sie nicht bezahlt. Daher würde nun ein Gerichtsvollzieher Ihren Hausrat pfänden. Achtung: Bezahlen Sie die Forderung nicht! Die Nachricht stammt nicht vom Finanzamt und Ihr Geld landet bei Kriminellen. --------------------------------------------- https://www.watchlist-internet.at/news/das-finanzamt-versendet-keine-pfaend… ∗∗∗ Security researchers targeted with new malware via job offers on LinkedIn ∗∗∗ --------------------------------------------- A suspected North Korean hacking group is targeting security researchers and media organizations in the U.S. and Europe with fake job offers that lead to the deployment of three new, custom malware families. --------------------------------------------- https://www.bleepingcomputer.com/news/security/security-researchers-targete… ∗∗∗ Medusa ransomware gang picks up steam as it targets companies worldwide ∗∗∗ --------------------------------------------- A ransomware operation known as Medusa has begun to pick up steam in 2023, targeting corporate victims worldwide with million-dollar ransom demands. --------------------------------------------- https://www.bleepingcomputer.com/news/security/medusa-ransomware-gang-picks… ∗∗∗ DEV-1101 enables high-volume AiTM campaigns with open-source phishing kit ∗∗∗ --------------------------------------------- DEV-1101 is an actor tracked by Microsoft responsible for the development, support, and advertising of several AiTM phishing kits, including an open-source kit capable of circumventing MFA through reverse-proxy functionality. --------------------------------------------- https://www.microsoft.com/en-us/security/blog/2023/03/13/dev-1101-enables-h… ∗∗∗ Overview of a Mirai Payload Generator, (Sat, Mar 11th) ∗∗∗ --------------------------------------------- The Mirai[1] botnet is active for years. It was the first botnet targeting devices running Linux like camera recorders. Our first diary about it was in 2016![2]. Still today, my honeypot is hit by hundreds of Mirai requests every day! I found a Python script that generates a Mirai payload (SHA256:f56391e9645df1058847e28af6918c64ddc344d9f328b3dde9015213d5efdc7e[3]) and deploys networking services to serve it via FTP, HTTP, and TFTP. Nothing very fancy but it will give you a good idea about how Linux hosts are abused to deliver malicious payloads. --------------------------------------------- https://isc.sans.edu/diary/rss/29624 ∗∗∗ BATLOADER Malware Uses Google Ads to Deliver Vidar Stealer and Ursnif Payloads ∗∗∗ --------------------------------------------- The malware downloader known as BATLOADER has been observed abusing Google Ads to deliver secondary payloads like Vidar Stealer and Ursnif.

The videos lure users by pretending to be tutorials on how to download cracked versions of software such as Photoshop, Premiere Pro, Autodesk 3ds Max, AutoCAD, and other products that are licensed products available only to paid users. --------------------------------------------- https://cloudsek.com/blog/threat-actors-abuse-ai-generated-youtube-videos-t… ∗∗∗ Persistence - Context Menu ∗∗∗ --------------------------------------------- Context menu provides shortcuts to the user in order to perform a number of actions. The context menu is invoked with a right mouse click and it is a very common action for every Windows user.
