GDPR Article 14(5) provides a general tool for resolving that conflict: you don’t need to inform if doing so “is likely to render impossible or seriously impair the achievement of the objectives of that processing”. --------------------------------------------- https://regulatorydevelopments.jiscinvolve.org/wp/2021/12/22/attackers-csir… ∗∗∗ Microsoft Teams blockiert Notrufe mit Android-Handys – Update einspielen ∗∗∗ --------------------------------------------- Die Android-App für Microsoft Teams kann unter Umständen Notrufe vom Handy verhindern.

The latter option was used by REvil, Snatch and BlackMatter as a way to disable a target's intended security and IT admin tools. As Sophos points out, many endpoint security products do not run in Safe Mode – a special diagnostic configuration in which Windows disables most third-party drivers and software, and can render otherwise protected machines unsafe. --------------------------------------------- https://www.zdnet.com/article/this-new-ransomware-has-simple-but-very-cleve… ∗∗∗ Log4j Vulnerabilities: Attack Insights ∗∗∗ --------------------------------------------- Symantec [..] has observed numerous variations in attack requests primarily aimed at evading detection.
