Global ransomware attacks on the rise

According to Check Point Software Technologies, a data security solutions vendor, global ransomware attacks doubled during the second half of 2016. In the first half of the year, the percentage was 5.5%, while in the second half of the year, it jumped to 10.5%.

Their report highlights three of the main categories of malware:

– Mobile

– Banking

– Ransomware

In the previous year, they observed several new types of ransomware, with the numbers easily extending into the thousands.

Doros Hadjizenonos, Check Point SA’s country manager, claims that ransomware attacks are growing rapidly. The reason behind it is that because this type of malware is effective in terms of generating revenues for the attackers. Apart from that, Hadjizenonos also mentioned that many organisations do not educate their staff on how to recognise the signs of a potential ransomware attack in an e-mail.

In 2016, Check Point discovered the Mirai botnet, which is the first known IoT botnet. It has the function of attacking vulnerable connected devices such as surveillance cameras and video recorders, essentially turning them into bots. The compromised devices are then used to launch a series of DDOS attacks.

Finally, Check Point reports that malicious downloaders that download malware on your computer were the most prevalent infection vector.

Kaspersky Lab notes that in 2016, a huge amount of malicious spam was recorded. The most common form of malware were Trojan downloaders that downloaded ransomware to the victim’s computer. The Locky encryptor was the most commonly used ransomware by far, but others such as Shade, Petya, and Cryakl were also widespread.
