More and more, ransomware strains are going after not just main data stores, but backups as well. Newer strains like KeRanger and Samas are designed specifically to go after backups, making them even more destructive than past ransomware strains.
For many businesses and individuals, the ransomware situation can certainly appear to be quite dire. If even backups are not a failsafe, then what can be done to protect all data from these kinds of attacks?
The first step in ransomware prevention is education. Knowing not to download unknown email attachments or click the wrong link can go a long way towards ensuring that ransomware never makes it into the network. Limiting access rights to only a select few can help a lot in this regard as well.
Backups are still necessary, but they need to be effectively safeguarded as well. Be sure to back up data early and often, and make sure backups are located in disparate places. Also be sure to test backup recovery efforts consistently, and don’t keep backups on drives that are easily discovered by cybercriminals. Backing up changes incrementally, as opposed to overwriting files during each backup, can help as well.
Furthermore, robust endpoint and network gateway protection can help keep computers, workstations, backups and everything else in the network that much safer, as does active patch management.
Ransomware is becoming more insidious seemingly by the day. But, by knowing how it often appears, the threat it poses can be mitigated.
