This is done by making the malicious process look like it was spawned by another process. This helps evade detections that are based on anomalous parent-child process relationships. --------------------------------------------- https://captmeelo.com/redteam/maldev/2021/11/22/picky-ppid-spoofing.html ∗∗∗ Command injection prevention for Python ∗∗∗ --------------------------------------------- This is a command/code injection prevention cheat sheet by r2c. It contains code patterns of potential ways to run an OS command or arbitrary code in an application. Instead of scrutinizing code for exploitable vulnerabilities, the recommendations in this cheat sheet pave a safe road for developers that mitigates the possibility of command/code injection in your code. --------------------------------------------- https://semgrep.dev/docs/cheat-sheets/python-command-injection/ ∗∗∗ Missing Link: Wie sicher ist der Anonymisierungsdienst Tor? ∗∗∗ --------------------------------------------- Tor gilt als Wunderwaffe gegen den Überwachungswahn von Geheimdiensten.

(arXiv:2111.10167v1 [cs.SE]) ∗∗∗ --------------------------------------------- This paper introduces Amaranth project - a solution to some of the contemporary security issues related to UEFI firmware. In this work we focused our attention on virtual machines as it allowed us to simplify the development of secure UEFI firmware. Security hardening of our firmware is achieved through several techniques, the most important of which are an operating system integrity checking mechanism (through snapshots) and overall firmware size reduction. --------------------------------------------- http://arxiv.org/abs/2111.10167 ∗∗∗ Oh ...

Das heisst, es sind nicht einzelne Clients, Workstations oder Server auf Windows Betriebsystem-Ebene, sondern alle Maschinen, die virtualisiert - auf zum Beispiel VMware ESXi oder Microsoft Hyper-V - laufen, gleichzeitig betroffen.
