Security software experts identified a malicious program targeting Sony Corp.'s PlayStation Portable systems that is the first so-called Trojan horse found in video game devices.
Symantec Corp. said Thursday that the Trojan horse represented a low-level threat, affecting only machines that users have modified with their own code. A Trojan horse is a destructive program that masquerades as a harmless application.
"It does not affect the average user," said Eric Chien, a principal software engineer at Symantec. "This is the first time we have seen a Trojan on a gaming device."
The malevolent program says it is a file named "EXPLOIT 2G PSP Team V1.RAR" that allows users to run their own code on the Sony devices but in fact destroys the machine, Chien said.
