The recent Log4j vulnerability (CVE-2021-44228) is unprecedented in its global scope and impact. This open source logging framework for Apache is found buried in everything from the Mars Helicopter to Minecraft. The exploit is as simple as getting the system to log a message containing a specific string, which can be done as easily as changing your iPhone’s name, sending a chat message, or visiting a website.

In July, Eric & Whitney gave a talk titled "Breaches Be Crazy" at the SANS DFIR Summit outlining Recon’s unique approach at scaling enterprise forensic timelining.

It’s that time of year again - DEF CON! We were thrilled to run OpenSOC again at DEF CON this year, even if it had to be virtual (fingers crossed we’re all in person again in 2022).

Recon's SOC recently responded to an attempted ransomware and extortion attack. It had all the markings of a nightmare scenario: malicious access through the VPN, an external server in the same IP block as the Colonial Pipeline incident, Cobalt Strike flying across the environment, and a system running an unauthorized copy of MEGAsync. We attributed the attack to a Ransomware-as-a-Service (RaaS) threat group, likely DarkSide, REvil, or their affiliates.

The Recon incident response team recently responded to a case of business email compromise.  The incident spanned over seven months of potential dwell time, and included the unraveling of encrypted malware hidden in an image file. Our analysis attributed the incident to a threat group known as TA551/Shathak, known for stealing banking credentials.

Whether your cybersecurity detection and response capabilities are in-house or managed through a partner, a prioritized approach to threat hunting is a key indicator of your security program’s maturity and effectiveness.

We can't start a recap post without a huge THANK YOU to the community for joining us last week and making SOC X such a success!

Now that we've normalized and enriched our events, let's get into the actual threat detection logic that brings SIEM-like features to open source Graylog.

In my previous post, I explained the fundamental purpose and use cases of pipelines in Graylog – now let's move towards some more advanced topics.

If you are here hoping to learn more about using Graylog for the purpose of monitoring the security posture of your organization, strap in – it's about to get real.
