The Problem: Ransomware Follows the Money
Europe has become ransomware’s preferred hunting ground. After a global lull, gangs are targeting EU organizations and their suppliers with renewed intensity. The reasons are predictable: strong economies, strict data protection regulations that increase pressure to pay, and a dense network of supply chain relationships that amplify the impact of a single compromise.
But here’s what the article doesn’t say: the technical mechanism of these attacks hasn’t changed. Ransomware still works the same way it did five years ago. A payload lands on a Windows system, executes, and begins encrypting files. The regional shift is just evildoers optimizing their target selection — the attack itself is identical.
That means the defense can be identical too. And it can operate at a point in the attack chain where the regional surge is irrelevant.
Why Signature-Based Defenses Keep Failing
Most organizations defend against ransomware by trying to recognize it. Antivirus software, endpoint detection tools, and email filters all work by identifying known threats. A security researcher finds a new ransomware variant, analyzes it, creates a signature, pushes an update, and your tools learn to block it.
That process takes time. Hours, sometimes days. The window between a new ransomware release and when your defenses can detect it is exactly when attacks happen. Ransomware groups know this and exploit it deliberately — they test their payloads against common antivirus tools before launching campaigns.
The EU surge isn’t happening because organizations aren’t patching fast enough or because their antivirus is out of date. It’s happening because the recognition-based model is fundamentally reactive. You can’t recognize a threat you haven’t seen before.
How FileSure Blocks Ransomware Before It Executes
FileSure doesn’t try to recognize ransomware. It controls what programs are allowed to do to your files at the Windows kernel level, intercepting file operations before they complete.
Ransomware has to write an executable payload to disk before it can run. There’s no way around this. Whether it arrives via a phishing email, a compromised website, or a supply chain attack, the payload has to land on your file system as an executable file.
FileSure blocks that write operation. Here’s a specific rule configuration that stops email-based ransomware delivery:
File name filter: *.exe;*.dll;*.bat;*.cmd;*.ps1;*.vbs;*.js
Program name filter: \outlook.exe;\thunderbird.exe;\winmail.exe
Operations: Write, Create
Drive type: Hard drives
Result: Email clients cannot write executable or script files to local drives. Phishing attachments that attempt to drop payloads are blocked regardless of the malware variant.
The payload never lands. It never executes. Your files are never touched. This works on ransomware variants from this morning the same way it works on variants from five years ago, because the mechanism being controlled — the file system write operation — hasn’t changed.
The EU ransomware surge doesn’t require new defenses. It requires defenses that don’t depend on knowing what’s coming.
