Security vendor Trusteer has found a professional calling service that caters to cybercriminals. The business offers to extract sensitive information needed for bank fraud and identity theft from individuals. Staff are trained to impersonate bank employees, computer technicians, travel agents, recruiters and other people to whom targeted individuals are likely to disclose information. Users should treat all unsolicited calls with caution, regardless of what kind of information the person on the other end of the line has about them, Trusteer says.”]
