Original release date: July 18, 2019
The Canadian Centre for Cyber Security (CCCS) has released an advisory on an Astaroth fileless malware campaign affecting Microsoft Windows. Astaroth resides solely in memory, and an attacker can use it and other fileless malware to steal information, such as credentials and keystrokes, and obtain other sensitive data.
The Cybersecurity and Infrastructure Security Agency (CISA) encourages administrators to review CCCS’s Fileless Malware Advisory for potential infection vectors and recommended mitigations and refer to CISA’s Tip on Protecting Against Malicious Code.
