Many analysts rely on Windows Event Logs to help gain context of attacker activity on a system, with log entries serving as the correlative glue between additional artifacts. But what happens when the attackers find ways to remove the logs, or worse, stop the logs from writing? We must find a way to adapt.
In part 1 of this series, SANS instructor and incident responder Matt Bromiley focuses on techniques, old and new, that attackers are using to neutralize event logs as a recording mechanism. Ranging from clearing of logs to surgical, specific event removal, in this webcast we will discuss how the attackers are doing what they’re doing, and the forensic techniques we can use to detect their methods. There has been a lot of discussions lately about attackers’ ability to fool the system into not writing event logs – but are our attackers truly staying hidden when they do this? Let’s find out!
