RESEARCHERS WARN OF FLAWS THAT ALLOW MANIPULATION OF MICROSOFT TEAMS MESSAGES

Summary from the TLDR InfoSec newsletter

Researchers from Check Point have discovered four vulnerabilities that allow attackers to manipulate Teams messages. The vulnerabilities could allow attackers to edit Teams messages without leaving the “edited” label, alter message notifications so they appear to be from a different sender, change the display name inside private chats, and alter caller identities in video and audio calls.
