Filter Out the Noise
Since I started this curated newsletter in June 2017, I’ve clipped ~17,000 articles and narrowed them down into the best 20 per day & best 15 per week. This is my favorite way to cut through all the security marketing and hype. If you’re enjoying it, tell a friend. If you hate it, tell an enemy.

13. Anatomy of Ryuk Attack: 29 Hours From Initial Email to Full Compromise (SecurityWeek, Oct 12 2020)
In the case of the attack observed by the DFIR Report, it all started with a malicious email that carried a link to download the Bazar/Kegtap loader, which injects into multiple processes, and which performs reconnaissance on the infected system, using Windows utilities like nltest and net group, as well as third-party tool AdFind.
The malware remained quiet for roughly one day, after which a second reconnaissance phase was launched, using the same tools, plus Rubeus. Data was exfiltrated to a remote server and the attackers started lateral movement.
To compromise additional systems on the network, the attackers used various methods, including remote WMI, remote service execution with PowerShell, and a Cobalt Strike beacon dropped over SMB. Next, the Cobalt Strike beacon was used as the main pivotal point.
Additional beacons were then established across the environment and PowerShell was employed to disable Windows Defender. Ryuk was executed one minute after being transferred over SMB from the pivot and, once encryption started, the servers used to store backups were hit first.
