This interesting finding could lead to malware possibly being bypassed when processing web pages containing underlying scripts embedded in the HTML.

QUOTE: When I found a malicious script riddled with 0×00 bytes, SANS handler Bojan Zdrnja explained to me that this was an old trick. When rendering an HTML page, Internet Explorer will ignore all zero-bytes (bytes with value zero, 0×00). Malware authors use this to obscure their scripts. But this old trick still packs a punch.

When I remove all obscuring zero-bytes from this script, things get better: 25 out of 32 AV products detect it. But what happens when I add more zero-bytes to the script?  Even more AV are fooled! Gradually adding more zero-bytes makes the detection ratio go down.

And at 254 zero-bytes between the individual characters of the script, McAfee VirusScan is the only AV to still detect this obscured script. One byte more (255 zero-bytes), and VirusScan doesn’t detect the script anymore.  No AV on VirusTotal detects this malware obscured with 255 zero-bytes (or more). But for IE, this obscured HTML poses no problem, it still renders the page and executes the script.
