Intego’s Virus Monitoring Center has spotted a variant of the RSPlug.A Trojan horse. This variant, discovered on November 21, and called OSX.RSPlug.B, is identical to the first version of the Trojan, with the exception that its installation script is encrypted. This is done in an attempt to fool antivirus software. Intego’s virus team has updated its VirusBarrier definitions. Those dated November 22, 2007 protect against this new variant.
