Adobe code signing infrastructure hacked by 'sophisticated threat actors'

Adobe has warned that an internal server with access to its digital certificate code signing infrastructure was hacked by "sophisticated threat actors" engaged in "highly targeted attacks."

The compromise, which dates back to early July, led to the creation of at least two malicious files that were digitally signed using a valid Adobe certificate, according to Adobe security chief Brad Arkin.

Although only two files were signed, the hack effectively gave the attackers the ability to create malware masquerading as legitimate Adobe software and signals a raising of the stakes in the world of Advanced Persistent Threats (APTs). Guardtime keyless signatures were not in use, thereby allowing the tampering to go undetected.

Beware of PDFs booby-trapped by cybercriminals which can infect your computer and even potentially enable the attackers to gain access to your corporate network. These PDFs may be sent to victims via spam, or they may be planted on websites where they sit, waiting for unsuspecting visitors to click on them.

These booby-trapped PDFs exploit vulnerabilities in PDF-reading software such as Adobe Reader. The simple act of opening them can initiate automatic downloading of malicious code from the Internet and the decoy PDFs that are displayed cover up the malicious activity.

When was the last time you updated your applications like Adobe Reader with the latest security patches? Watch this video by Chet Wisniewski and see how hackers can leverage PDFs to pwn your computer.
