Was great to be back in person in our hometown of Austin, Texas. Thanks to everyone that braved the wintry weather and came out in honor of our #VeteransDay2022 #MerivisMixer! Tag any friends you see in the photo, there's quite a few of 'em! #merivets #salesforceatx

Are folks actually seeing much attack activity using #PrintNightmare vulns? The talk is way worse than what I'm seeing so far - mostly pentesters so far #cybersecurity #dfir #ThreatHunting #vulnerability


A lot of you out there must actually prefer your IoCs in pdf format... #threathunting #dfir #CyberSecurity


#Exchange servers continue to be hit by the exploits disclosed last week. Novel ransomware attacks were confirmed today (thanks @malwrhunterteam) but so far has been light, expect it to heat up soon for those who haven't patched or removed backdoors from previous exploitation

Microsoft observed a new family of human operated ransomware attack customers – detected as Ransom:Win32/DoejoCrypt.A. Human operated ransomware attacks are utilizing the Microsoft Exchange vulnerabilities to exploit customers. #DearCry @MsftSecIntel


This is worse than Solarwinds. If you have an online exchange server - you're declaring an incident right now. Sign up for a free trial instance of @InfocyteInc and scan your exchange servers with our Hafnum scanner (open source): infocyte.com/blog/2021/03/0… #HAFNIUM #exchange #hack

Sources who've briefed U.S. national security advisors say >30K U.S. organizations hacked by newly-found holes in Microsoft's Exchange email products, and that 100s of thousands of victim organizations worldwide now have web-based backdoors installed. krebsonsecurity.com/2021/03/at-lea…

Awesome presentation by Mandiant pros on the return of Ryuk. Cobalt Strike is used in every attack (we see the same @InfocyteInc )

I'll attempt to live tweet this awesome webcast from @Wanna_VanTa and @x04steve on Ryuk and UNCs behind them! Roughly 1/5 ransomware intrusions have been related to Ryuk. @Mandiant @sansforensics

Really well done document on #incidentresponse

We partnered with @CyberCentre_CA, @NCSC, @CERTNZ, and @CyberGovAU on a Joint #Cybersecurity Advisory: cisa.gov/news/2020/09/0…. We’re working to enhance incident response to malicious cyber activity. #InfoSec #NetworkSecurity

If you can watch video after video of unnecessary deaths, accelerating protests, growing unrest, walkouts, anger in the streets and the only thing you can think or talk about is restoring “law and order” without a mention of justice or reform: you are part of the problem.
