Vulnerabilities & Exploits
- Ten years later, malware authors are still abusing ‘Heaven’s Gate’ Technique (ZDNet) July 2ndMore than ten years after it was first detailed in a hacker e-zine (online magazine), malware strains are still successfully using the “Heaven’s Gate” technique to avoid antivirus detection, even today.

Any malware using the Heaven’s Gate technique is effectively going after older systems, which shows once more why using a modern OS is always a good idea.
