Cyberattacks have entered a different phase as they force many companies to keep their guards up lately. What is even more alarming is the possibility that most of them would attack anyone vulnerable, whether the victim is an individual or a large corporation.
In response to these attacks, given that all are potential victims, IT departments are rushing to solidify their defenses to avoid their establishments from falling prey. With this in mind, companies must know how to react to a successful ransomware attack by setting up a proven threat hunting model.
During a ransomware attack, cybercriminals will hack into the system and make your data inaccessible. To restore the encrypted data you would need to pay a ransom, hence its name. Once paid, they will give you the decryption key to recover your data.
This encounter now begs the question: should we pay the attacker or not? Not everyone would advise you to spend on this, but you would end up worrying about the risks of what these cybercriminals would do to your info if you fail to meet their demands.
Determine The Scale Of The Problem
After falling victim to a ransomware attack, the first thing that you need to do is to assess the damage it had caused. The most common way of spreading this malware is through clicking on malicious links or emails, so if only one computer was compromised, you could just shut it down. However, if more computers were affected by the attack, you need to take more severe measures to contain the ransomware and stop it from spreading further.
Unplug The Computer Systems
To stop the spread of malware, disconnect all computer networks. This action prevents other computers from being infected by the attack. Additionally, inform offsite workers to disconnect their devices from the company network while the issue stands.
Maintaining communication with everyone is essential in the process of troubleshooting the damage, but beware of the possibility that the attacker is watching your every move. A good alternative would be to communicate through personal emails and chats while calling with your own mobile numbers for safety.
It is recommended to seek the aid of cybersecurity authorities in the event of a continuous ransomware incident that is causing prolonged damage to the company, especially during the process of recovering the files and data that were made inaccessible by the hackers.

During retrieval, it is crucial to identify the most important files to the company. These include essential data regarding the running and managing of daily activities within the firm. Those unaffected by the ransomware should also be noted and removed from the list of possible data to recover.
Inform Authorities, Employees, And Affected Customers
Report the breach to the authorities and see what help and advice they can offer to address the problem. Also, informing the other employees is a priority. They need to know how the ransomware attack could affect their jobs and understand that they need to cooperate until the company regains its normal state and recovers all the lost data.
Transparency is crucial amid scandals like this. Perform an email blast to your customers explaining all the possible effects on them, and be honest. However, only inform the customers after you already have a full grasp of what is going on. Ensure that they will hear what happened directly from the company and not from the media.
Update Cybersecurity Measures
The loss of the company and the overall damage that the cyberattack caused to its employees and customers must be documented and well recorded. Furthermore, an investigation is crucial to determine what went wrong and identify the vulnerabilities that made the attack possible.
Implement the highest standard when setting up preventive measures against future cyber threats to avoid more damage to the company. It is advisable to look at different tools of ransomware and other aggressive solutions like cyber threat hunting.
