Good afternoon, Talos readers.
We're used to referring to attackers as either APTs or not APTs. And when something is an APT, it sounds a lot scarier and sexier. But it's our belief that that isn't going to cut it anymore.
Therefore, we propose in a new blog post that there be a new group of threat actors known as "privateers." These groups benefit from a nation-state but can't be directly connected to a government. Find out more about these groups here .

Cisco Talos recently discovered an exploitable heap-based buffer overflow vulnerability in Google Chrome.
Google Chrome is a cross-platform web browser — and Chromium is the open-source version of the browser that other software developers use to build their browsers, as well. TALOS-2021-1235 (CVE-2021-21160) is a buffer overflow vulnerability in Chrome’s AudioDelay function that could allow an adversary to execute remote code. An attacker could exploit this vulnerability by tricking a user into visiting a specially crafted HTML page in Chrome. Proper heap grooming can give the attacker full control
