TeamSpy is back and it's turning TeamViewer into the spying tool that no one wants. According to security firm Heimdal, a new spam campaign emerged, carrying the TeamSpy malware which can give hackers full access to a compromised computer.

This isn't a new type of malware whatsoever. In fact, back in 2013, it was wrecking havoc in countless computers. Back then, attackers were gathering information from victims, be them ordinary users or high profile individuals working in industries or research. This time around, however, it seems that TeamViewer has not been compromised as it happened in the past, so reusing their passwords should be safe.

Several TeamViewer users have reported unauthorized access over the last few days, leading some to suspect that the remote connection company has been hacked. The unauthorized access reports started showing up on Reddit around the same time that the company suffered possible DNS issues that triggered an outage lasting for several hours.

In some cases, those users reporting the incidents on Reddit say their PayPal accounts, as well as Amazon accounts were raided – after the unauthorized user took advantage of stored credentials in the browser to conduct transactions.
