on a day with no ADHD meds, my roommate knocks on the door and is like "a friend got their discord hacked but before I knew it they sent me an EXE and I ran it. am I hacked?"

awfully lot of debugging information printed to console.log by this malware. it really tells you everything it is doing

I hope these fuckers aren't trying to obfuscate the password by abusing javascript scoping

sure there's work-from-home, but you're probably still within a reasonable driving distance of the office. they could just blacklist the entire metropolitan area

OH GOOD this is a different version that uses aes compression. so the source isn't just obfuscated, it's actually encrypted.

god I bet there are some malware out there that checks your location on GPS before running, and errors out if you're too close to Known Antivirus companies

there's a lot of very specific checks before it tries to do anything, I think this has been carefully designed to appear innocuous to the commonly used online sandboxes. like, it detects if it's running on virustotal and throws an error, instead of doing anything sneaky-deaky

yes let me accidentally try to unpack the electron app in poland, that's exactly the kind of protection I need: geographic protection

I'm looking at this disassembly from dez_ on twitter.

but yeah it does a bunch of checks to see if anything remotely debuggy or VMy is running or even installed, then refuses to do stuff

it even checks against OllyDbg, a really great debugger that hasn't updated in 11 years

huh, one of the things it does is check your RAM speed.
I think because that's a thing real computers have, and it's trying to do a roundabout VM check?

seems it is an electron based javascript malware that tries to steal all your passwords from all your browsers

@foone Electron-based malware... gonna need to sit down for a minute.
I guess when everything you install is yet another bespoke copy of Electron hogging all of your resources, one more copy of Electron could be a reasonable way to blend in.
I do kind of love the prospect that even malware developers are too cheap to bother with native platform development these days.

@foone I have run into malware that has server-side checks before the second stage would download and it blocked a couple major metropolitan areas and allow listed residential ISPs. Ended up buying a sacrificial laptop to infect.
