The number of attacks of ransom viruses on different companies has tripped in 2016. This means there was one attack every two minutes in January. By October, the rate of attacks had increased to one every 40 seconds. Attacks on private persons have increased from one attack every 20 seconds to one attack every ten seconds.

Baltic news, News from Latvia, BNN.LV, BNN-NEWS.COM, BNN-NEWS.RUMore than 62 new types of ransom viruses have appeared over the course of the year. This threat has grown so aggressively that Kaspersky Lab has named ransomware the main topic of 2016.

Among other things, experts found in 2016 that ransomware in business are largely attractive to criminals who lack skills, resources or desire to create one on their own. Depending on demand, ransomware developers offer their ‘products’ as uniquely modified versions to clients, who then distribute them using websites and SPAM, paying commission fee to the developer – the main beneficiary.

«It seems the classic business model with ransomware works as effectively as it does with other forms of malware. Unfortunately victims often pay the ransom, fuelling the system. This only leads to the escalation of the problem and the emergence of new types of encryption viruses nearly every day,» – says Kaspersky Lab senior malware analyst Fyodor Sinitsin.

Ransom viruses continued to emerge around the world in 2016, becoming more complex and varied and increasing the threat level for companies and private persons alike.

Attacks on companies have increased significantly. According to data from Kaspersky Lab, one fifth of companies around the world have experienced IT security breaches because of ransom virus attacks. One-fifth of those companies never recovered encrypted data after paying the ransom.

Some industries have suffered more than others. Study data shows there are no low-risk industries: the highest proportion of attacks is noted in education (23%) and the lowest is noted in retail trade and leisure (16%).

New approaches for ransom virus attacks that were first observed in 2016 include disk encryption; full or partial encryption depending of the type of virus. One of the best examples is Petya. Dcryptor, also known as Mamba, has gone a step further – it blocks access to the entire hard drive.

There has also been an increase in the number of simple Trojan ransom viruses appearing in the past twelve months. Poorer quality software increases the risk of victims never recovering their data.
