Most ransomware variants demand a ransom in the $75-$200 range from individual victims, with some skewing higher or lower. This change is a strategic one from the attackers’ [perspective.

A year later, that number had almost doubled to more than 13 percent. In 2014-15, enterprise users accounted for about 7 percent of all ransomware victims. The number of enterprise users attacked by crypto ransomware also is on the rise. TeslaCrypt, together with CTB-Locker, Scatter and Cryakl were responsible for attacks against 79.21% of those who encountered any crypto-ransomware.” “A year later the situation had changed considerably. Between them they were able to attack 101,568 users around the world, accounting for 77.48% of all users attacked with crypto-ransomware during the period,” Kaspersky said in its new report. In the first period, from April 2014 to March 2015, the most actively propagated encryptors were the following groups of malware: CryptoWall, Cryakl, Scatter, Mor, CTB-Locker, TorrentLocker, Fury, Lortok, Aura, and Shade. “Looking at the malware groups that were active in the period covered by this report, it appears that a rather short list of suspects is responsible for most of the trouble caused by crypto-ransomware. wp-content/uploads/2016/06/Ransomware-podcast.mp3 Kaspersky’s researchers said the spike in crypto ransomware can be attributed to a small group of variants. It didn’t just burst onto the scene a couple of years ago. That’s a massive increase, especially considering the fact that ransomware is a somewhat mature threat. Data compiled by Kaspersky researchers from the company’s cloud network shows that from April 2015 to March 2016, the volume of crypto ransomware encountered by users leapt from 131,111 to 718,536. Security researchers have been publishing decryption tools for specific ransomware variants and law enforcement agencies have had some success in taking down ransomware gangs.īut the problem of ransomware itself is only getting worse, and it shows no signs of abating. The FBI has been warning users about crypto ransomware for some time now, and has consistently advised victims not to pay any ransoms.

It’s difficult to overstate how much of an effect the emergence of ransomware has had on consumers, enterprises, and the security industry itself. The variety and volume of ransomware being deployed by attackers has continued to grow at an alarming rate in the last year or so, with pioneering strains such as CryptoLocker, CryptoWall, and others being joined by dozens of new variants. New stats released by security researchers at Kaspersky Lab show that the number of users who came across crypto ransomware in the last year increased by more than 500 percent over the previous year. There appears to be no end in sight to the ransomware epidemic.
