Ransomware Groups Turn to Citrix Bleed 2, BYOVD, and Supply Chain Credentials — Because Apparently Patch Management Is Still Too Fucking Hard

Right, here we go. The article says ransomware crews have shifted their grubby little paws toward a lovely cocktail of Citrix Bleed 2, BYOVD (“bring your own vulnerable driver,” for those not already dead inside), and supply chain credentials. In other words: attackers are no longer just rattling the doorknob — they’ve found the spare key, nicked the landlord’s master fob, and brought a crowbar for good measure. Splendid.

The big headline is that criminals are exploiting Citrix NetScaler flaws, including what’s being called Citrix Bleed 2, to hijack sessions and worm their way into enterprise environments. If that sounds familiar, it’s because the original Citrix Bleed already taught everyone this lesson, and apparently a terrifying number of organizations responded by learning absolutely fuck-all.

Once inside, these charming bastards are using BYOVD techniques to disable security controls. That means they bring along legitimately signed but vulnerable drivers, abuse them, and use the trust baked into the system to blind EDR and other defenses. It’s one of those beautifully stupid tricks where security software sees a signed driver and thinks, “Well this must be fine,” right before it gets smacked in the face with a shovel.

The article also points out the increased use of compromised supply chain credentials. That’s attacker-speak for: “Why bother smashing the front window when some supplier already left us a valid badge?” If third-party access is poorly monitored — and let’s be honest, it usually is — ransomware crews can move in through trusted relationships while everyone stares at dashboards insisting all systems are nominal. Marvelous.

The overall trend is the same old shit, just polished: attackers are chaining edge-device exploitation, credential abuse, and defense evasion into faster, nastier intrusions. Hit the internet-facing appliance, steal sessions or creds, pivot inward, kill security tooling, and deploy ransomware when the victim is good and helpless. Efficient, ugly, and depressingly effective.

The takeaway, for those in the back eating paste, is that organizations need to patch internet-facing systems quickly, lock down third-party and supplier access, monitor session abuse, and stop assuming signed drivers are automatically trustworthy. Also: segment your network, rotate credentials, enforce MFA properly, and maybe stop treating your VPN and ADC estate like forgotten shit in a cupboard.

In summary: ransomware gangs are getting better at combining old holes, new holes, trusted access, and defensive blind spots into one streamlined extortion machine. And defenders are still acting shocked — shocked — that exposed appliances, stale credentials, and lazy controls lead to catastrophe. It’s like watching someone store petrol next to a bonfire and then complain about the fucking heat.

Related anecdote: years ago, I watched a sysadmin insist a gateway appliance was “too critical to patch during business hours,” then “too risky to patch after hours,” and finally “scheduled for next quarter” right up until some enterprising bastard turned it into an unauthorized public-access tunnel. The post-incident meeting featured a lot of buzzwords, several useless PowerPoints, and one very quiet manager pretending this was unforeseeable. It was foreseeable, you useless sacks of wet paperwork.
