I’ve put together this blog post as a reminder that security organizations—and quite frankly, boards and executive leadership—should view internal security threats just as seriously as external ones when it comes time to protecting their organization’s sensitive information. --------------------------------------------- https://www.safebreach.com/moveit-vulnerability-a-painful-reminder-that-thr… ∗∗∗ Gaps in Azure Service Fabric’s Security Call for User Vigilance ∗∗∗ --------------------------------------------- In this blog post, we discuss different configuration scenarios that may lead to security issues with Azure Service Fabric, a distributed platform for deploying, managing, and scaling microservices and container applications. --------------------------------------------- https://www.trendmicro.com/en_us/research/23/f/gaps-in-azure-service-fabric… ∗∗∗ GitHub Dataset Research Reveals Millions Potentially Vulnerable to RepoJacking ∗∗∗ --------------------------------------------- Millions of GitHub repositories are potentially vulnerable to RepoJacking.

More recently, there was a sample where a normal installer was downloaded and executed. If the malware is executed in an ordinary user environment, the encrypted malware file is downloaded from the threat actor’s server and executed. --------------------------------------------- https://asec.ahnlab.com/en/54658/ ∗∗∗ Tsunami DDoS Malware Distributed to Linux SSH Servers ∗∗∗ --------------------------------------------- AhnLab Security Emergency response Center (ASEC) has recently discovered an attack campaign that consists of the Tsunami DDoS Bot being installed on inadequately managed Linux SSH servers. Not only did the threat actor install Tsunami, but they also installed various other malware such as ShellBot, XMRig CoinMiner, and Log Cleaner. When looking at the attack cases against poorly managed Linux SSH servers, most of them involve the installation of DDoS bots or CoinMiners. --------------------------------------------- https://asec.ahnlab.com/en/54647/ ===================== = Vulnerabilities = ===================== ∗∗∗ Router-Firmware: Asus rät aufgrund kritischer Lücken dringend zum Update ∗∗∗ --------------------------------------------- Asus hat in der Firmware für mehrere Router-Modelle kritische Schwachstellen geschlossen, die Angreifer potenziell bösartigen Code ausführen lassen. --------------------------------------------- https://www.golem.de/news/router-firmware-asus-raet-aufgrund-kritischer-lue… ∗∗∗ Zyxel security advisory for pre-authentication command injection vulnerability in NAS products ∗∗∗ --------------------------------------------- The pre-authentication command injection vulnerability in some Zyxel NAS devices could allow an unauthenticated attacker to execute some operating system (OS) commands remotely by sending a crafted HTTP request.

They are simple text files and contain setup information in a driver package. They describe what must be performed to install a driver package on a device. When you read them, the syntax is straightforward to understand. The file is based on sections that describe what must be performed.

The firms blog post is full of interesting details about how this device works (and doesnt), but a key takeaway is that you can predictably trigger a buffer overflow by passing the device a name longer than its 30-character limit -- a limit enforced solely by Wemos own apps -- with third-party tools. --------------------------------------------- https://it.slashdot.org/story/23/05/17/141200/wemo-wont-fix-smart-plug-vuln… ∗∗∗ Respawning Malware Persists on PyPI ∗∗∗ --------------------------------------------- A bad actor on GitHub laces his repositories with malware written in Python and hosted on PyPI. Minutes after his malware is taken down from PyPI, the same malware respawns on PyPI under a slightly different name. He then immediately updates all of his repositories to point to this new package. Most of his GitHub projects are bots or some variety of a stealer. --------------------------------------------- https://blog.phylum.io/respawning-malware-persists-on-pypi/ ∗∗∗ Neue Scam-Website im Umlauf: finanavas.com ∗∗∗ --------------------------------------------- Investmentbetrüger versuchen mit einer neuen Website Leuten Geld aus der Tasche zu ziehen.

Mandiant’s investigation revealed that the attacker employed malicious use of the Serial Console on Azure Virtual Machines (VM) to install third-party remote management software within client environments. This method of attack was unique in that it avoided many of the traditional detection methods employed within Azure and provided the attacker with full administrative access to the VM. Unfortunately, cloud resources are often poorly misunderstood, leading to misconfigurations that can leave these assets vulnerable to attackers. While methods of initial access, lateral movement, and persistence vary from one attacker to another, one thing is clear: Attackers have their eyes on the cloud. --------------------------------------------- https://www.mandiant.com/resources/blog/sim-swapping-abuse-azure-serial ∗∗∗ CISA and Partners Release BianLian Ransomware Cybersecurity Advisory ∗∗∗ --------------------------------------------- CISA, the Federal Bureau of Investigation (FBI), and the Australian Cyber Security Centre (ACSC) have released a joint Cybersecurity Advisory (CSA) with known BianLian ransomware and data extortion group technical details. Microsoft and Sophos contributed to the advisory. To reduce the likelihood and impact of BianLian and other ransomware incidents, CISA encourages organizations to implement mitigations recommended in this advisory. --------------------------------------------- https://www.cisa.gov/news-events/alerts/2023/05/16/cisa-and-partners-releas… ===================== = Vulnerabilities = ===================== ∗∗∗ Webbrowser: Kritische Sicherheitslücke in Google Chrome ∗∗∗ --------------------------------------------- Google hat ein Update für den Chrome-Webbrowser herausgegeben.
