A new backdoor Trojan is targeting Mac users, says security firm Sophos. The attack is delivered via a client called BlackHole RAT, which in turn is based on Windows software known as darkComet. RAT is described by as "very basic," and effectively a beta, as even its creator admits that it's unfinished. It can nevertheless do some serious damage, as it allows an attacker to run shell commands or pop up a fake "Administrator Password" window to phish a person's account data.
