SideWinder’s New ClickOnce Crapfest – Because Apparently We Needed More Malware in Our Miserable Lives

Well, grab your coffee and prepare to facepalm, because the lovely bastards from the SideWinder APT crew are back at it again — this time with some new ClickOnce-based malware bullshit that’s making the lives of South Asian diplomats a living digital hell. Apparently phishing through email attachments and fake URLs wasn’t enough, so now they’re dropping malicious apps disguised as “legit” installers. Bravo, SideWinder. Real f***ing original.

These digital degenerates are using Microsoft’s ClickOnce deployment — yeah, that handy “install this quickly” feature — to sneak their toxic trash into systems. They whip up a fake application, toss it into your inbox wrapped in something that looks official as hell, and bam! You’re owned faster than an intern clicking “Run Anyway” on a sketchy .exe they downloaded from a cat meme forum.

The payload? Same old sh*t: espionage, data theft, credential harvesting — the usual lineup of digital robbery that makes security teams age ten years in a sprint. This isn’t their first rodeo either. SideWinder’s been poking at governments, defense outfits, and diplomatic targets across South Asia for bloody years, perfecting their nasty little craft like evil artisans of malware misery.

To make it worse, this ClickOnce horseshit bypasses some security controls because, let’s face it, half the corporate world still gives admin rights to users like candy at Halloween. So they run the app, it installs itself with a smile, and suddenly your diplomatic secrets are being uploaded to some basement in another hemisphere. Lovely, just lovely.

So yeah — patch, update, disable ClickOnce if you can, and for the love of all that’s binary, teach users not to click every shiny thing that shows up in their inbox. Or don’t, and we’ll all watch another embassy get digitally pantsed by a couple of hackers who probably think 2FA means “Too F***ing Annoying.”

Reminds me of the time I told a user not to open strange attachments — next day, they brought their laptop with more malware than a 2000s torrent site. I wiped the drive, handed it back, and told them it was “upgraded.” They never noticed I installed Linux. Idiot-proofing level: Bastard.
