Informational POC


Multiple information-stealing malware families are abusing an undocumented Google OAuth endpoint named "MultiLogin" to restore expired authentication cookies and log into users' accounts, even if an account's password was reset.
Rhadamanthys, Risepro, Meduza and Stealc Stealer adopted this technique. On December 26, White Snake also implemented the exploit.
