New .NET CAPI Backdoor Targets Russian Auto and E-Commerce Firms via Phishing ZIPs
Well, looks like the titanic circus of cybersecurity fuckery keeps spinning its flaming wheels. Some sneaky bastards have cooked up a shiny new .NET-based backdoor called “CAPI” — and before you ask, no, it doesn’t stand for “Can Anyone Patch It?” even though they bloody should. This little gremlin is slithering into Russian automotive and e-commerce companies through good old-fashioned phishing ZIP files – because apparently, clicking random attachments never gets old.
Once the poor unsuspecting sods unzip the “document” sent by some alleged “supplier,” bam! They get a delightful payload that phones home to some sneaky-ass command-and-control servers. From there, the nasty bit of code downloads other malware modules, giving the attackers remote access and exfiltration powers. You know – the usual “we own your system now” hacker power trip.
The backdoor cleverly abuses the Microsoft Cryptographic API (hence the sexy “CAPI” name) to encrypt its communications, meaning defenders get to have all the fun of watching encrypted garbage fly past their firewalls while wondering what the hell went wrong. Researchers say the campaign smells state-sponsored – someone’s flexing their cyber muscles again, and surprise, surprise, it’s supposedly targeting Russian firms. The geopolitical irony writes itself.
Anyway, if you’re the kind of moron clicking random ZIP attachments in 2025, you deserve every byte of digital misery coming your way. The moral here? Stop opening shit from strangers. Stop trusting emails promising invoices, salary reports, or horny singles in your area. You’re not missing anything except a one-way ticket to ransomware hell.

Anecdote: This reminds me of that time some idiot in accounting ran an EXE from a flash drive titled “TAX_REBATE_2023.” Took down half the network before lunch. I told them I’d fix it “next quarter” — after the mandatory sacrifice of a printer and 30 minutes of name-calling. Moral? Always assume your users will click the stupidest possible thing.
