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.
