Files stolen from a sneaky SymStealer.

Show Notes

Ron Masas of Imperva discusses their work, the "Google Chrome “SymStealer” Vulnerability. How to Protect Your Files from Being Stolen." By reviewing the ways the browser handles file systems, specifically searching for common vulnerabilities relating to how browsers process symlinks, the Imperva Red Team discovered that when files are dropped onto a file input, it’s handled differently.

Dubbing it as CVE-2022-40764, researchers found a vulnerability that "allowed for the theft of sensitive files, such as crypto wallets and cloud provider credentials." In result, over 2.5 billion users of Google Chrome and Chromium-based browsers were affected.
