Finjan builds defense against PDA attack

InfoWorld |  Hardware

SECURITY SOFTWARE COMPANY Finjan Software announced the release of an application on Tuesday to protect computer systems from attacks launched from PDAs (personal data assistants).

San Jose, Calif.-based Finjan's SurfinShield Corporate monitors the behavior of executable programs synchronized from Palm Pilots to corporate PCs, according to a company release. The application looks for active Web content, such as ActiveX, Java scripts, and executable programs coming in over a synchronization link to a PDA, and prevents content that breaches security policies, such as attempting to delete a file or open a network connection.

Researchers at anti-virus software companies discovered two viruses in September that affect Palm operating systems. The "Liberty Crack" Trojan horse program can potentially wipe all the files from a Palm handheld computer but is considered by experts a low risk for permanent damage. The more malicious "Palm OS/Phage" virus fills a device's screen with a gray box, ends the application that is running, and then duplicates itself to other applications. Phage is considered a "wireless" virus because it can be transmitted via infra-red beam link to another computer.

In August, Network Associates' McAfee division released McAfee VirusScan Wireless. The application runs on PCs and scans incoming data from PDAs, looking for viruses.
