MessageLabs Ltd. has detected a new form of spam that attempts to hide itself from content filters and human recognition by masquerading as legitimate email among IT staff. The new spam messages include words and phrases such as “.NET,” “XSS,” or trouble ticket numbers. The spam, which was likely created by top spam minds in Russia, creates an ironic twist: IT staffers falling for the same spam they always warn users not to open. MessageLab expects the spammers to expand their exploits to other industries, such as accounting or legal firms.”]
