Notorious Jigsaw Malware makes a Comeback

Jigsaw, an infamous malware responsible for massive financial losses among consumers, is back once again. A recent report by ZDNet said that hackers are once again utilizing revamped Jigsaw malware to continue stealing more through a simple yet efficient tactic.


As per reports, the malicious software was first seen in 2016, appearing as a ransomware that would steal user data and demand Bitcoin as a ransom to release the information back. Jigsaw ransomware also got its name from a film under the same title, comparing the code to the movie’s main antagonist. 

Since its first appearance, the recently spotted Jigsaw malware is an upgraded version and operates undetected by altering a user’s address. After breaking in, every Bitcoin payment is rerouted into the offender's account. It achieves this by manipulating addresses on a clipboard. 

Despite that, Jigsaw doesn’t only steal Bitcoin, it also mimics the user’s address through other programs and appears as the original owners address, tricking them into thinking nothing is wrong. Jigsaw also appears to be an effective criminal method. Fortinet, the first to shed light on the malware stated that it has been the primary cause in more than $60K losses in the current price. The company also mentioned many related projects used to alter addresses being promoted on the dark web. 

Price doesn’t matter

Jigsaw and its method were never mentioned in the latest report by Malwarebytes, a cybersecurity firm. A report earlier stated that both ransomware and crypto-jacking, another malicious method of mining through an unauthorized computer, are the leading cause of crypto-threats.

With that said, even as these activities have slowed down in light of the poorly performing markets and coin prices, the CT&T has stated that crypto jacking is declining, although they continue to reign over digital threats given their primary status. As we enter the third quarter of this year, Malwarebytes is confident that these criminal activities will slowly wither away since criminals are, by nature, attracted to the biggest busts they can find.

Malwarebytes spoke about how criminals were not stealing as many funds as they could through crypto-jacking and that crypto mining will drop during the third quarter. As clipboards continue to have their addresses altered and manipulated, this threat will most likely see a more effective future in the crypto-sphere due to its non-intrusive methods to make a profit for criminals.
