As incident responders we don’t often get to talk about the work we are most proud of, that’s why this story of how we defeated encryption used by a nation state sponsored ransomware is one of the projects that I have been most excited to write about. So happy it’s finally out!

Better later than never, @barnhartguy & @_scrapbird The Log4J Rollercoaster presentation from @DianaInitiative was released: youtube.com/watch?v=CB5Z-M…
[1/4] If you've followed our team's recent work, you probably noticed our obsession with MS-RPC. Today we release RPC Toolkit - a collection of blog posts, tools, vulnerability write-ups and PoCs that we either created or relied on during our research. github.com/akamai/akamai-…
With the increasing targeting of organizations with MFA bypass techniques we would like to recommend our research on the topic to help security teams: medium.com/proferosec-osm…
It’s been an absolute blast at #defcon and so great to meet everyone for the first time including some work mates (@barnhartguy ) but time to get some vitamin D on this pale skin after a week spent in Vegas 😂

The log4j rollercoaster - from incident response prospective. By our very own @_scrapbird and @barnhartguy at @DianaInitiative youtu.be/eZbdkSyK2a0?t=…
Thanks so much to everyone who made @hackeriot_org happen! I had an amazing time at the conference. It was fantastic that the @ProferoSec team put on such a great workshop for women wanting to get into cyber security and incident response - not just how they fit into a SOC!
Very excited for my first hacker summer camp :)

As an Incident response team, we see a lot of cloud breaches that could have been prevented. In the following blog post on @cloudsa we share case studies from the trenches and how you can prepare for them. By @_scrapbird Senior Incident Responder & team - cloudsecurityalliance.org/blog/2022/02/1…
Stay tuned, we will be providing instructions for #binlex to collect data in @MongoDB soon. Build your own corpus and do complex similarity analysis with Compass at scale. Using docker-compose, build your own Intezer in no time, and its FREE! 😅 github.com/c3rb3ru5d3d53c…
Watching the blame game for #log4j got us thinking about the broken OSS model. People working for zero pay, nights and free time, and not getting recognition or pay while the big products who benefit from their labor remain silent. We can do better medium.com/proferosec-osm…
Probably the most comprehensive Regex I’ve seen yet to identify Log4Shell exploitation attempts: github.com/back2root/log4… #CVE-2021-44228 #Log4j
#log4j (H/T @colemankane )
#Dridex is getting more unstable by the minute. On clean vanilla systems its injection mechanism (dridex payload living inside explorer) keeps causing process crashes. Must be fun operating a botnet where you think EDR blocked things, but nope, your bot just crashed? 🙃
