While it’s imperative to lose calm if one is found under a ransomware attack, one should not panic. The right approach to mitigating such attacks can help you save money and the organization’s reputation.
Mitigation is crucial when dealing with a ransomware attack. In this blog, we have discussed some dos and don’ts of dealing with ransomware cyber-attacks.
Most companies are tempted to remove the ransomware as soon as they discover it. However, any steps taken in haste can make you susceptible to further attacks. In addition, business owners should keep in mind that the company’s data and reputation are at stake in ransomware.
Step 1: Isolate the network traffic to mitigate the risk of further adversity.

One can use this information to build effective countermeasures in the event of an attack. If you restart or reboot assets, it will clear the live memory of the application used to attack the network. This will wipe out the data that can help one trace the attacker managed IT services companies suggest that instead of shutting the servers, isolating them is the best option.
