TOP VULNERABILITY THIS WEEK: Emotet returns after a quiet summer
=========================================================
NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: New Emotet campaign emerges, but protection stays the same
Description: At the beginning of June 2019, Emotet’s operators decided to take an extended summer vacation. Even the command and control (C2) activities saw a major pause in activity. However, as summer draws to a close, Cisco Talos and other researchers started to see increased activity in Emotet’s C2 infrastructure. And as of Sept. 16, 2019, the Emotet botnet has fully reawakened, and has resumed spamming operations once again. The malware still mainly relies on socially engineered spam emails to spread. Once the attackers have swiped a victim’s email, Emotet constructs new attack messages in reply to some of that victim’s unread email messages, quoting the bodies of real messages in the threads.
