The results of 2017: the top 5 powerful cyber attacks in the opinion of Global Threat Intelligence

Malicious software spared no effort in reaching private and business accounts. According to Global Threat Intelligence Report 2017, during the 12 month period 6.2 billion attempted attacks were detected.

Osiris, Cerber, and Locky are not just good names for your dog, they are nightmares for any vulnerable workstation around the globe.

This year’s attacks were somewhat nontraditional and impressed security specialists with the new techniques and tools. Most of them were aimed at causing as much financial damage per user as possible. Cyber attacks will remain the greatest threat to companies around the world. Let’s have a look at 2017’s top 5 “harvests” according to Hideez. These examples are not the leastor the last and everyone should know how they can protect their personal accounts or businesses from ransomware.

No1 Petya

This popped up on researchers’ security radar in March. It didn’t encrypt user’s files directly, it encrypted the master file table that NTFS disks use to keep info about the location, size, and file names on the physical disk. Petya replaced the operation system’s bootloader with its own malicious code. Thus, your computer just can’t boot. Also, Petya does its best to obtain administrator privileges. This ransomware gets in using an age old technique: the user gets a fake job application. They click on it, and Petya colonizes their virtual property.

No 2 NotPetya

NotPetya started its activities as a fake tax software update. It is a variant of a modernized Petya attack. The difference is that this ransomware uses the same malicious code as WannaCry. The software which is applied to devices spreads from network to network like a swarm. It was aimed at damaging the infrastructure of a country – banks, supermarkets, airports – and succeeded for some period of time. It was not only aimed at earning money, about 300 in bitcoins per victim, but probably the main point was destroying everything along the way. More than 150 countries were infected.

No 3 WannaCry

WannaCry was spread through spam emails. The content of the malicious letter included fake job offers, invoices, and other .zip archives that, after opening, spread the ransomware through the victim’s PC. The user just clicked the download button and the ransomware got to work.

No 4 Locky

This was born in 2016, and in 2017 was still feeling good. Locky is a phishing email attack. Emails that seemed like like Herbalife, Amazon invoices or something like that, contained zipped malicious attachments. The users had to pay from 1 to 40 bitcoins to get access to their systems again. It sent more than 20 million spam message per day. We hope you were not among the victims.

No 5 Cerber

Cerber was nominated as one of the most prolific threats among crypto-malware. It steals passwords and cryptocurrency from victims. Spread all over the world through Remote Desktop Protocol (RDP), ransomware as a service (RaaS), and of course spam email. Еhis malware not only encrypts data on the computer but also removes automatic backups from it. As with most malware, CrySis demands bitcoins.
