After WannaCry and NotPetya, ransomware dwindled in 2017

After a year of headline-grabbing ransomware campaigns, it looks like hackers are launching the attacks less frequently.

Ransomware is malicious software that can lock up your files until you send hackers a ransom payment. It featured in the WannaCry attacks in May and the NotPetya attacks in June, both of which swept through hospitals, banks and governments in several countries. But after July, the rates of ransomware infections dropped sharply, according to a report from Malwarebytes.

If the trend continues, it would mean a reprieve from an attack that targeted institutions where time is money, like banks, or where lives could hang in the balance, like hospitals.

So why would hackers ditch one of their favorite attacks? It turns out that computer users have a really valuable tool against ransomware: backing up their files. 

 

That's according to Chris Boyd, a malware analyst at Malwarebytes, who told ZDNet that publicity around the major ransomware attacks probably helped educate people about how to avoid needing to pay by uploading files to the cloud or a backup device. 

"This alone, even without additional security precautions, effectively deadens the otherwise considerable sting of the threat," Boyd told ZDNet, a CNET sister site. The company sells a product that detects and blocks malicious software for businesses and regular computer users.

That's not to say hackers aren't hacking. They've simply turned to other kinds of attacks to steal money, such as banking trojans and adware, both of which are old-school hacking tricks.

Hackers are also still innovating. Adam Kujawa, director of malware intelligence at Malwarebytes, said the biggest trend he observed in December was the rise of "crypto-jacking." That's when websites you visit secretly use your computer's processing power to run a program that creates bitcoins. 

That lets hackers make money off your computer. And, Kujawa said, "it wears down resources really fast," slowing down your computer's performance.

But hey, at least you can still access your files.
