- 4. What is Ransomware • Ransomware is a strain of malware (malicious software) that encrypts or locks all of the files on your computer or server, and then demands a payment (or ransom) to unlock your files. • It takes many forms, including its most infamous incarnation, Cryptolocker. • Other strains include Locky, Teslacrypt, and Cryptowall. • In some instances, ransomware’s presence can be betrayed by a .EXE file extension - but cyber criminals are getting more and more sophisticated, so this often isn’t the case.
- 5. How Does Ransomware Spread ? • Like many viruses, the most common source of infection is from emails, when a user opens contaminated attachments or clicks a malicious link. However, there are many other sources, like rogue USB sticks, or even joining free WiFi networks. How can I Remove it ? • Unfortunately, there’s no sure-fire way to remove Ransomware. • Even paying up doesn’t always work; criminals have been known to ask for higher and higher sums, or claim to have lost the ‘key’. • The best approach is to access your backups.
- 6. What can I do to avoid Ransomware? • There are three major forms of protection: • Preventative measures, • Anti-virus & backup. • Preventative measures are the first lines of defence against Ransomware: education can ensure that staff are aware of the risks and know what to look out for, and changing system permissions can lower the risk of infection. • Anti-virus is a must for all businesses, and can detect and deflect a high percentage of attacks.
- 7. What can I do to avoid Ransomware? Cont’d • However, due to the ever-changing nature of Ransomware, these steps aren’t 100% effective. That’s when you need a backup and business continuity solution. This allows you to roll back to a point prior to infection.
