The brutal increase of ransomware continues: there are more than 120 families

Phishing and malware campaigns, specially ransomware, have experimented an amazing increase the first three months of the year, estimated on 789% by the company PhishMe. Other people talk about an increase of 3.500% in the infrastructure and network use to support the ransomware campaigns. A group of independent researchers has created a database of all the specimens of ransomware known until now, which already has more than 120.

This database, with every technical detail to facilitate the work to researchers, is increasingly growing and now 124 variant have been already catalogued. From virulent specimens like Locky or Cryptolocker, controlled by individual bands, until others used by people who but the service in the black market and they haven't got any experience on computing. Bart Parys, security investigator who has taken part in the creation of the database about the different ransomware families, explain the ransomware success secret is "the return of the investment is high".

Also, add Raj Samani, Europe technology chief for Intel Security, the ransomware is easy to use, it gives low risk and allow get large profit. To top, the situation getting worse with the "apparition of free ransomware source code and the line services that allow to "amateurs" enter in the business".

Another indicator of the increase of ransomware attacks is the network infrastructure used by the bands who take profits with this malware: domain, payment structures and others are increasingly more than ever, has ensured to press the Infoblox security vicepresident, according to BBC. To the criminal pattern shown by the virus until now: infection and explotation, the ransomware add a third benefit: blackmail.

"Thus far in 2016, we have recorded an unprecedented rise in the encryption ransomware attacks, and we see no signs of this trend abating. Individuals, small-and medium-sized businesses, hospitals, and global enterprises are all faced with the reality that this is now one of the most favored cyber criminal enterprises", explains Rohyt Belain, CEO of PhishMe
