We've preserved (yet another) lot of eleven test cartridges for the Nintendo DS, DSi, and 3DS! Included are some never-before-seen pieces of test software, as well as new versions of previously discovered ones! Thanks to those who contributed: March42, Kc57, Haifisch, and XX_75.
Check out my latest blog post about Cova loader and Nosu stealer. These two went unnoticed... but only until now :) bitsight.com/blog/cova-and-…
Wish I knew why my @analogue pocket order has been "processing" at the fullment partner for more than a month now while others who have ordered at the exact same time have gotten theirs a while ago now 😔
Bankrupting Twitter is not an eligible run submission for the second submission period.

Main concern w/ the new Twitter Blue offering is the verified logo has been a marker of trust I.e., “we’ve confirmed the person is who they say they are.” Now it’s “we’re taking their $ & their word for it.” On the cusp of election where source of info is critical, a major risk.

To think that simple payment verifying will pose any sort of meaningful barrier to sophisticated actors on the platform is just not anchored in reality. Agree w/ @ianbremmer

Reminder: We are constantly pushing new C2s/Distro URLs/Payload URL/samples to the abuse.ch ecosystem. Please see our submissions at bazaar.abuse.ch feodotracker.abuse.ch threatfox.abuse.ch urlhaus.abuse.ch for more details and info.
We have been busy and improved MalwareBazaar's archive parsing 🆕⬇️ The password of PW protected archives is now guessed from the tag list provided 🔐 E.g.: 👉 bazaar.abuse.ch/sample/ddfdea4… We have also implemented a feature to de-pump pumped files 📄 E.g.: 👉 bazaar.abuse.ch/sample/0819fa0…
Okay, so a few people have asked how you spot the where your Trust Thermocline is, and how to avoid hitting it. I'll give you the same answer I give senior execs: I don't know. But the people working on the ground level in the customer-facing sections of your company do. /1

One of the things I occasionally get paid to do by companies/execs is to tell them why everything seemed to SUDDENLY go wrong, and subs/readers dropped like a stone. So, with everything going on at Twitter rn, time for a thread about the Trust Thermocline /1
I know what I'm doing, but I also have no idea what I'm doing.
Rest in peace, Vitali. Our thoughts and prayers are with your family and friends. Thanks for all you did for the cybersecurity community.
