Less than one week after the official rollout of Microsoft's new operating system, hackers are already attempting exploits. According to a blog post from Trend Micro, at least two separate exploits are already in operation. One involves fake antivirus; the other is a phishing attempt that offers users a free Windows 8 upgrade if they fill in fields that provide exploitable details.

"It just confirms that the bad guys will use the news to effectively perpetrate a crime," said Jon Clay, security technologist at Trend Micro, in an interview with CRN . "They've turned around the fake AV presence very quickly. Their use of Windows 8 security pop-ups in their fake AV scams shows how quickly they can utilize the latest news in perpetrating crime."
