Ransomware defined and explained
20 Oct, 2022 54 ViewsThe defining feature of ransomware is that it attempts to trick or force its victim into paying to regain access to their data. Different forms of ransomware take different strategies to achieve this.
Encryption ransomware attacks are very hard to treat Getting rid of the encryption ransomware itself is not necessarily difficult. Usually a security scan will do the trick. The problem is that getting rid of the source of the infection will not treat the symptoms. In other words, your files will stay encrypted. You may be able to find a decryption tool that will release your data again, but frankly you will need a bit of luck on your side for this to work. Bluntly, enough organizations pay the ransom (against all advice) that cybercriminals are both able and willing to put time into continually developing their malware so it keeps jumping ahead of security products and decryption tools. This means that the only really safe approach is to focus on prevention (and protection) rather than cure. Prevention means security, protection means data backups The fact that ransomware creators are continually updating their malware means that you can never be 100% safe against it even with the best security processes in the world. That should not, however, stop you from trying, if only to save yourself the hassle and downtime caused by having to restore data from a backup, very possibly an offsite backup. Effective data backups are your only guaranteed protection against having to accept the loss of your data (or grit your teeth, cross your fingers and pay up), but the key word in that sentence is “effective”.
Scareware, lockware and encryption ransomware Scareware and lockware both prey on ignorance, fear, and intimidation. Scareware, as its name suggests, has nothing behind it and can usually be removed very easily if the user just keeps calm. Lockware really does lock users out of their computer but it can generally be bypassed by anyone with enough IT knowledge to boot into safe mode with command prompt and restore to a date before the infection. Encryption ransomware is generally used to target organizations. Unlike the other two main forms of Ransomware, it really does pose a serious threat. As its name suggests, it encrypts files to try to force organizations to pay to regain access to them.
