Thousands of companies have been victimized by these ransomware actors resulting in significant monetary losses, and the worst sensitive company data are being sold off to the black market giving other malicious actors to further cause damage to the victimized company.

Current statistics show that from a mere small-time attack in 2015 that reported paid a total ransom of USD 354 million, the estimated projected ransom that has been extorted to victims will sum up to USD 20 billion in 2021. This was reported due to the countless ransomware attack incidents that have been reported that have been boost benefitting from the current pandemic situation.

This is an addition to the fact that ransomware application has been sold to the black market as ransomware-as-a-service. Thus, many adversaries can create a more advanced type of program that could bypass security software installed by many companies that can only detect known ransomware program.

For the above reason, cybersecurity experts are calling out to also have open communication, and rather than being reactive on ransomware attacks, they are suggesting being more proactive in battling these adversaries. Few suggestions includes to (1) always have an  offline backup of important document that can be immediately uploaded onto the system to ensure operation continuity in case adversary encrypt/locked current data, (2) use segmented type of data storage so that adversary cannot completely encrypt immediately the whole data storage, (3) proactively search for indicators of compromise within the network, (4) limit individuals with elevated access as their profile is usually the main target of these actors, (5) disconnect the access of company devices to social media as malicious actors frequently use this as gateway through the company resources, (5) install latest security software and patches from legitimate developers, and lastly, (7) in case attack has been successful, immediately contact authority and seek assistance in dealing with the adversary as they are well trained to handle such situations, and lastly, (8) ensure that company the security team always provide awareness and current information to end-users as the infection always starts with them.

Following such a suggestion may not entirely free a company from a possible attack, but this will help a lot in battling these malicious actors and minimize their damage to the cybercommunity.
