Kaspersky Lab Says Cybercriminals are Moving from Ransomware to Cryptojacking
June 30, 2018 11:26 am
Kaspersky Lab, a global cybersecurity company, has published a report saying there has been a particular change from ransomware-related attacks for mining malware. The report says this type of attack called cryptojacking has become a more possibility for hackers and that why the number of ransomware attacks is dropping.
Last year, Ransomware like WannaCry made global destruction after spreading to the various organization which includes multiple UK National Health Service hospitals across England Scotland. The ransomware targeted a Microsoft Windows exploit, encrypted all user files on a computer and demanded bitcoin payments as a ransom for unlocking the files. Anyhow, the report suggested them as an “isolated surge than a trend.”
The report says:
“The total number of users who encountered ransomware fell by almost 30%, from 2,581,026 in 2016-2017 to 1,811,937 in 2017-2018.”
The number of ransomware attacks was declined in 22.5 percent
The report also mentioned that the number of users who found malicious miners grew by almost 44.5% in the last year. Factors like the simple monetizing model of mining, discreteness of mining software, and the expertise of creating these miners all have contributed in making cryptojacking a more lucrative attack vector compared to ransomware.
Mobile-based mining attacks have seen a constant growth along with PC based attacks. Although PCs provide more computational power for mining.
The report stated:
“Both percentages and absolute figures show us that mobile mining is an emerging threat, targeting developing countries.”
Developing countries like India and China make up for a one-third of the market share for smartphone devices. The report also discussed browser-based mining that is carried out by executing a particular script into the victim’s web page.
The report included:
“The number of targeted attacks on businesses, to install miners, raises questions about whether mining might eventually follow in the footsteps of ransomware actors. Big money loves silence, and if miner actors attract as much attention to themselves as ransomware did, life will get complicated for them.”
