LeakNet ransomware is actively abusing Microsoft Teams as a social engineering delivery channel, alongside compromised websites, to distribute a ClickFix-style lure that triggers msiexec.exe-based delivery of a Deno in-memory loader and subsequent ransomware execution. No CVE is involved; the attack chain exploits user execution and Teams’ external messaging functionality rather than a software vulnerability. Organizations should restrict external account messaging in Teams, block or alert on Deno runtime execution enterprise-wide, and apply AppLocker or WDAC rules to prevent msiexec.exe from retrieving and executing remote payloads.
