A Critical Google Cookies exploit involves manipulating or stealing user cookies, which store authentication information, to gain unauthorized access to accounts.
A developer, PRISMA, discovered a major Google cookie exploit in Oct 2023 that allows persistent access post-password reset.
A threat actor later integrated it into Lumma Infostealer, causing a ripple effect across malware groups.
Cybersecurity researchers at Cloudsek recently identified a new critical Google Cookies exploit that enables threat actors to persistently gain Google access after a password reset.
Malware reverses to target Chrome's WebData token service table that helps in extracting:-.
The table holds crucial columns like:-.
Chromium's source code unveils the MultiLogin endpoint, an internal sync mechanism for Google accounts.
It aligns browser account states with Google's authentication cookies for a consistent user experience.
Several attempts were made to locate it using Google Dork, but all of them were unsuccessful.
The MultiLogin endpoint manages simultaneous sessions by accepting account IDs and auth-login tokens.
This undocumented MultiLogin endpoint, a crucial part of Google's OAuth system, allows for the regeneration of cookies.
Lumma's sophisticated approach involves encrypting the token: GAIA ID pair, blackboxing the exploit and adding secrecy to its core mechanics.
Black boxing serves two purposes, and here we have mentioned them:-.
Lumma's sophisticated exploit manipulates the token: GAIA ID pair, enabling continuous cookie regeneration for Google services.
Alarming is its persistence post-password reset, which allows:-.
Encrypting the key component signals a shift towards advanced, stealth-focused cyber threats, highlighting the stealth and protection of exploit methodologies in malware development.
