A security software vendor called Tier-3 has warned IT administrators that a type of script called Zero Byte are still capable of fooling the latest malware detection software.

“Now it appears that malware authors have stumbled on the fact that many of today’s 32 and 64-bit IT security software still limit their signature analyses to the first 256 or 512 bytes of a script. If a script is padded out with a lengthy string of zero byte entries, then it follows that a modern script can pass unnoticed and wreak havoc on a Windows-driven computer system,” said Geoff Sweeney of Tier-3.
