Ransomware threat to Hungarian SMEs

The biggest security danger of 2015 is likely to be the ransomware

In the first few weeks of 2015 several Hungarian enterprises became victims of a malware attack which encrypts the files found on the infected computer and on other computers, servers connected to the same network. The criminals demand a ‘ransom’ to decrypt the data, but even though the companies pay, there is no guarantee that they will actually get back the valuable files and information essential to the day-to-day business operations. The problem cannot be solved, but it can be prevented.

Noreg recommends the following steps to prevent such infections:

  • Never open the attachments of unsolicited emails. It is highly recommended in case of the ransomware, because it spreads mainly this way.
  • Use the same security settings and precautions on tablets and smartphones as well, since those are just as likely targets nowadays as the computers. 
  • Always conduct regular system back-ups and store them offline.

According to a report by DellSecure, the ransomware called Cryptowall had infected 600.000 computers by August 2014, and is still active. The malware is compatible with both 32-bit and 64-bit systems which means that the risk of infection is getting higher and higher.
