Hackers are moving from ransomware to cryptojacking, Kaspersky Lab reported on 28th June.

The Russian cybersecurity firm Kaspersky Lab has published a report regarding the ransomware attacks and hackers’ preferences.

Ransomware is more a blackmail measure rather than a malware infection. Once users have accessed the malicious link usually received by mail, the computer becomes infected. Thus, the software has access to all the documents on the device, threatening the user to delete them. To prevent this, hackers ask for a reward, usually in Bitcoin (BTC).

According to the report, cases of ransomware attacks have been halved lately, indicating that hackers are more interested in crypto mining malware. We should not be surprised once mining activities are more profitable.

Kaspersky Lab has a tradition of reporting on the evolution of ransomware … This year, however, we came across a huge obstacle in continuing this tradition. We have found that ransomware is rapidly vanishing and that cryptocurrency mining is starting to take its place,” states the report.

Ransomware decreases- Mining malware increases

According to a press release published on 27th June, after comparing the data from April 2016 to March 2017 with records from April 2017 to March 2018, Kaspersky found that cases involving ransomware attacks had dropped by 44.6%, while mining malware increased by 44.5%.

Here are some of the main findings by Kaspersky:

  • “The proportion of users who encountered ransomware at least once out of the total number of users who encountered malware fell by around 1 percentage point, from 3.88% in 2016-2017 to 2.80% in 2017-2018;
  • The total number of users who encountered miners rose by almost 44.5% from 1,899,236 in 2016-2017 to 2,735,611 in 2017-2018;
  • The share of miners detected, from the overall number of threats detected, also grew from almost 3% in 2016-2017 to over 4% in 2017-2018;
  • The total number of users who encountered mobile miners also increased – but at a steadier pace, growing by 9.5% from 4,505 in 2016-2017 to 4,931 in 2017-2018.”

The cybersecurity firm assumes that the number of cryptojacking on crypto mining devices will increase. Here’s what the company wrote in the report:

It is highly likely that the additional growth of mining will come at the expense of mobile miners. For now, they are growing, but at a very steady pace. However, once criminals find a technological solution that makes the profits from mining on mobile devices equivalent to those from mining on PCs, mobile mining will quickly become equal.”
