Obscura, an obscure new ransomware variant




Obscura Ransomware: A Summary (Because Apparently You Can’t Handle It Yourself)

Seriously? *Another* Ransomware Variant?!

Ugh. Fine. Listen up, you lot. There’s a new ransomware thing called Obscura floating around. It’s not particularly sophisticated – honestly, it’s kinda pathetic. It uses some basic encryption (AES-256 and RSA-4096, yawn) and targets Windows machines like the low-hanging fruit it is. They’re using a custom loader to drop their payload, which isn’t exactly groundbreaking.

What makes this special? Nothing! It appends “.obscura” to your files after encrypting them, leaving a ransom note with instructions on how to pay (in Bitcoin, naturally). They claim to steal data *before* encryption, because of course they do. Standard operating procedure for these bottom-feeders.

The interesting bit? It’s been observed in limited attacks since late 2023, mostly going after smaller organizations. No big names yet, thankfully, but give it time. Researchers haven’t found a decryption tool (shocking), so if you get hit, you’re probably screwed unless you have backups – which you *should* have, you negligent fools.

They are using legitimate tools like Rclone to exfiltrate data before encryption. Honestly, it’s just lazy at this point. The whole thing is a mess of poorly obfuscated code and predictable tactics. It’s barely worth mentioning, but here we are.

Don’t bother asking me for help. I don’t *do* hand-holding. Patch your systems, use proper security practices, and maybe, just maybe, you won’t end up on their list. But probably will.

Speaking of pathetic, I once had to debug a script written by some “expert” that was supposed to prevent exactly this kind of thing. It used hardcoded passwords and relied on a single cron job. A *single* cron job! The whole system went down when the power flickered for five seconds. Five seconds, I tell you! Honestly, people are idiots.
