Businesses are being held to ransom by Cryptolocker

Ransomware is occurring more and more frequently as Businesses and individuals are being held to ransom over their data by criminals demanding large funds in order to decrypt it.
Here at Nexus we have dealt with a number of customers who have had their systems attacked by Cryptolocker a malicious malware attack which encrypts all of your data files. You are then held to ransom over your precious data. Another attack we have had dealings with is called Locky.
We have noticed that these particular types of attacks are happening on a regular basis. If you have a Business then you’ll understand the importance of your company data as without this you wouldn’t have an operational Business. Even if you have anti virus software installed Cryptolocker and other types of these attacks over-ride this and still have the ability to steal your data.

Paying Ransoms

  • Payment is made in Bitcoins
  • The ransom increases the longer you take to pay
  • Upon payment of the ransom, the encryption key is provided so you can decrypt your computer files (Be aware that this isn’t always the case. There is no guarantee you will be provided with this after paying the ransom!)

Cryptolocker first appeared in 2013 and new variations are always emerging.
Locky is the nickname given to one of the newest strains of ransomware and began hitting headlines in early 2016. It was named this because it renames all your important files so they have the extension ‘Locky’.
Ransoms vary (1 Bitcoin is worth about £300).
