APT28 Targeted European Entities Using Webhook-Based Macro Malware

APT28’s Webhook Wankfest: Because Macros Weren’t Shitty Enough Already

Oh, for fuck’s sake. Just when I thought the average user’s stupidity had hit rock bottom, APT28 comes along with a goddamn jackhammer. These Russian twatwaffles are now abusing webhooks in their macro malware campaigns against European entities, and frankly, I’m almost impressed by the sheer balls of it. Almost.

These bastards are using weaponized Office documents—because apparently, twenty fucking years of warnings about macros wasn’t enough—and embedding them with VBA scripts that phone home via legitimate webhook services. Discord, Slack, Teams, you name it. Why pay for C2 infrastructure when you can piggyback on some poor sod’s collaboration tools for free? It’s the digital equivalent of shitting in someone else’s swimming pool and letting their mates deal with the cleanup.

The attack chain is laughably simple, which makes it even more depressing that it works. Phishing email arrives, user dribbles on their keyboard in excitement, opens the attachment, clicks “Enable Content” because the big yellow bar looks lonely, and BAM! Their machine is now a fucking information piñata for the GRU. The malware uses these webhooks to blend into normal traffic, bypassing all those expensive security tools management forced me to implement. Thanks, Kevin from Accounting. Your “invoice.xlsm” just cost us our entire Eastern European customer database.

Technical details? Sure, why not. The macros are obfuscated—surprise, fucking surprise—with string concatenation and environment variable tricks. They dump base64-encoded payloads, execute them, then use Discord’s webhook API to exfiltrate data. The beauty is it looks like normal traffic to your shitty IDS. The ugly is that I’m going to have to block Discord company-wide, and the entire marketing department will have a collective aneurysm.

Indicators of Compromise? Let me save you the trouble: If you see any Office doc with macros that isn’t one of the three templates I personally approved, it’s compromised. If you see traffic to webhook URLs from user machines, it’s compromised. If you see a user actually working and not browsing Facebook, they’re probably compromised. Just burn the whole fucking network and start over.

Mitigation? Here’s a thought: Disable macros. I know, revolutionary shit. But since management thinks users “need them for productivity,” how about we just disable the users instead? Failing that, block every webhook service known to man, implement application whitelisting, and replace everyone’s machine with a Etch A Sketch. At least then the worst they can do is draw boobs and send them to HR.

Right, anecdote time. Last week, some dipshit in Sales clicked on a “Q1 Bonuses.xlsm” that arrived from “microsft-support@outlook.co.ru” at 3 AM on a Sunday. The webhook malware started spamming our company Slack channel with base64-encoded garbage. I could’ve just blocked it, but where’s the fun in that? Instead, I let it run for six hours while I “investigated,” then told management the breach originated from his machine because he disabled his firewall to “stream Netflix in better quality.” He’s now got a mandatory security awareness course every fucking morning at 6 AM for the next year, and I get to watch him suffer via webcam. Sometimes, the job has its perks.
