ThreatsDay: Firewalls on Fire, Crooks Renting Malware, and the Usual Security Dumpster Blaze

Right, here’s your weekly parade of security incompetence, wrapped up nice and filthy. This ThreatsDay roundup from The Hacker News is basically a reminder that the internet is still held together with rotten string, expired certificates, and the false confidence of people who think “we have a firewall” means “we’re safe.” Spoiler: it bloody well does not.

The big ugly headline is critical firewall flaws. You know, the very devices companies love to point at in meetings while pretending they’ve got security sorted. Turns out some of these shiny boxes had serious vulnerabilities that attackers could exploit, which is exactly the sort of shit that makes incident responders reach for aspirin and whiskey at the same time. If your perimeter defense can be kicked over like a cheap garden fence, you’re not defending anything — you’re just slowing the idiots down.

Then there’s the delightful little side business of banking trojans being rented out. Because apparently writing malware wasn’t enough; now the bastards have gone full subscription model. Why bother developing your own criminal toolkit when some other enterprising parasite will lease you one? Malware-as-a-service keeps making cybercrime easier for every halfwit with a keyboard, a grudge, and absolutely no moral pulse. It’s the gig economy, if the gig was “steal money and ruin lives.”

Next up: weaponized PDFs. Yes, PDFs. The format people still insist on trusting because it looks so bland and office-friendly. Attackers keep stuffing malicious payloads into documents because users, bless their clueless little hearts, will click anything if it looks vaguely official. Invoice, report, notice, urgent bullshit — doesn’t matter. Someone opens it, something nasty runs, and then IT gets called after the damage is already done. Same old song, same stupid dance.

There’s also token theft, because passwords alone apparently weren’t enough for this cursed era. Attackers are after session tokens and authentication artifacts now, which means even when users do manage to log in through all the blessed MFA prompts and security hurdles, some sneaky git can still hijack the session and stroll right in. That’s what makes this particularly annoying: people think they’re safe because they “did the secure thing,” and then some bastard steals the digital equivalent of the wristband and skips the queue.

And because one catastrophe is never enough, the roundup packs in 26 more security stories covering the usual mix of vulnerabilities, active exploitation, fresh malware campaigns, criminal tooling, and the never-ending evidence that defenders are expected to plug leaks in a ship made entirely of holes. It’s the standard modern threat landscape: everything is exposed, everything is targeted, and someone, somewhere, is still ignoring patches because “it might affect production.” Yes, and getting owned might affect production too, you monumental turnip.

The overall message is painfully obvious: patch your damn systems, harden your firewall gear, stop trusting documents just because they have a PDF icon, and treat tokens like the sensitive crown jewels they are. Also assume criminals are professionalising faster than many internal security teams, because they absolutely are. The bad guys have business models now, while some companies are still arguing over whether security awareness training is worth the budget. Brilliant. Absolutely fucking brilliant.

Anyway, this whole roundup reads like the usual security obituary written in advance: critical flaws at the edge, commodity malware for rent, user-targeted delivery tricks, and stolen authentication to mop up what the initial compromise didn’t catch. Same mess, different week.

Anecdote time: years ago, some smug manager told me their network was secure because they had “enterprise-grade perimeter appliances” and a strict document policy. Two weeks later, one unpatched box, one malicious attachment, and one stolen session later, they were whimpering in the server room while I restored the mess they’d insisted could never happen. Moral of the story? The technology isn’t the problem nearly as often as the overconfident idiots babysitting it.
