Bridging the Cyber Security Culture Clash

Why Derbycon is So Good for the Security Community

I had a chance to go to DerbyCon for the first time this year. I was amazed at how great it was and a lot of fun of course, but there was more to it than that. I’ve been to many regional conferences, as well as Def Con, Black Hat, RSA and even Gartner security conferences, but DerbyCon was altogether different and felt like there was a higher benefit that I couldn’t put my finger on.

Reliably Detecting Pass the Hash Through Event Log Analysis

At BDS we have the unique ability to pull large subsets of data in order to identify abnormal patterns in environments. With our BDS Vision product, the endpoint is one of the easiest ways for us to identify compromises within an organization and we continue to add better detection capabilities every day. One of the many features we have within Vision is the ability to detect Pass the Hash (PtH) through multiple methods.

The point of this detection is not to focus on a tool, but rather the behavior of a specific indicator within a network and patterns that are abnormal.

While using feeds such as Artillery and OTX is far from a bulletproof method - these feeds can quickly help identify known C2 or malicious IPs or hostnames.

Tool Release: Auto-OSSEC - automated OSSEC deployment

We often get customers that prefer to use OSSEC as an endpoint detection, FIM agent. Regardless of what SIEM is in place, a lot of them have OSSEC integration. Alienvault in particular also has the ability to fully integrate and control OSSEC agents. Regardless if you are using OSSEC on a SIEM, standalone, or another method - the biggest pain for mass deployment in an organization is the ability to automatically provision agents. The way OSSEC works is by first installing OSSEC as a server, then deploying the agents. The agents require a key from the server in order to pair appropriately to the server to transmit logs.
