Threat Source newsletter (Nov. 12, 2020)
Summary: Cisco Talos published new research on a CRAT trojan that carries ransomware, and Microsoft's November Patch Tuesday disclosed roughly 120 vulnerabilities, 18 of them rated critical, across products including HEVC, Azure Sphere and Exchange. Talos also issued an advisory on a recent spike in ransomware targeting health care organizations, and Adobe patched Acrobat Reader flaws including a heap buffer overflow and use-after-free found by Talos researchers.
Why it matters: Talos's own advisory flags a ransomware spike against health care organizations, and its Acrobat findings show that a malicious web page or crafted email attachment is enough to trigger the bugs - so patching and user awareness are the only barriers between a routine click and an exploit.
