Adobe Reader X stops malicious PDF spam

It looks as though Adobe's new Reader X incorporates a number of security features that block exploits that cybercriminals have tapped in previous Reader viewer applications. Sophos products, he adds, detect the attack as Mal/PDFEx-J. When opened by Adobe Reader 8, Baccas says that the PDF displayed nothing, but does attempt to download and run malicious code from a Colombian TLD.

There are so many reasons why you should download the most up-to-date version of Adobe Reader X, and one of those is to stop PDF spam attacks. We cannot stress how important it is to have Adobe Reader X, as this latest software did not suffer any such attack.

Knowing that the latest version of Adobe Reader was able to stop this attack surly has to be reason enough to download it now. Adobe's Reader X, last year's upgrade that features a "sandbox" designed to protect users from PDF exploits, stymied a recent attack campaign, researchers said Thursday.

The same malware, which first was noticed by security firms last October, runs correctly when aimed at Adobe Reader 8, however. The malformed PDF tries to exploit an already-patched vulnerability in older versions of Reader, said Chet Wisniewski, a senior security adviser with the antivirus company.

Like Greamo, Wisniewski wasn't able to definitively credit Reader X's sandbox for blocking the attack. "Was it the sandbox or that the malware was designed for Reader 8 and 9, not Reader X? "[This malware] wouldn't have worked in any case, because the flaw it exploits only exists in older versions of Reader," Wisniewski said. At a minimum, Reader X is a win for Adobe, Wisniewski continued, because that version had eliminated the flaw.
