WinRAR Vulnerability Exploitation: Decode & Bolster Protection

The core of this attack is a flaw in how WinRAR handles archive structures. It allows an attacker to hide a malicious executable that runs automatically when a user simply tries to view a harmless-looking file.

Attackers often use themes like "Job Application," "Payment Invoice," or "Security Update" to create urgency.

This method bypasses traditional "safe habits" because the user never technically "runs" an executable; they believe they are just opening a document.

When a user double-clicks the PDF inside the archive to view it, the vulnerability causes WinRAR to execute the file in the matching folder instead. 🛡️ Why It Is Effective

The .rar archive contains a benign file, like Invoice.pdf , and a folder with the exact same name ( Invoice.pdf ).

Once triggered, these files often install Remote Access Trojans (RATs) like DarkMe or Remcos , giving hackers full control of your system. 💡 Prevention Tips
