Symantec (NSDQ:SYMC) told customers Thursday not to use pcAnywhere until the company can secure the PC remote control software following the theft of its underlying code by hacker collective Anonymous. Symantec issued the warning after completing an analysis of the source code taken by an Indian chapter of Anonymous from an unidentified third party. Samples of the code were given to Infosec Island, an online community of security professionals that handed the code to Symantec, the vendor reported about two weeks ago.
