According to Cybersecurity Ventures predictions, a new business was victim to ransomware every 11 seconds back in 2021 and will continue to rise the next years and reach every two seconds by 2031.

When time is of the essence and next steps are uncertain, organizations should consult with the experienced professionals at Ontrack to determine their best course of action.

Stop ransomware and recover your data

If your organization might be affected by ransomware:

  • Contain the attack by disconnecting infected machines from the network. 
  • Contact us as early as possible. Our team will provide a free consultation and advise on options for data recovery and how to prevent further potential data loss. 
  • Avoid do-it-yourself attempts to decrypt the affected data. Doing so could make future recovery attempts impossible.

What to do when you’re under a ransomware attack

If you find yourself infected by ransomware, you need first to find out what kind of ransomware it is before moving forward.

If you can’t get past a ransomware note on your screen, you probably have been infected by screen-locking ransomware. If you can browse through your apps but can’t open your files, movies etc., you have been hit with encrypting ransomware – the worst scenario of the two. If you can navigate your system and read all your files, then you have probably hit with a fake version of ransomware that is just trying to scare you into paying. To better understand what to do when you’re hit with both screen-locking and encrypting ransomware, we recommend the blog What is ransomware, and how do you prevent it?

Even with the best precautions and policies in place, you may still suffer from an attack. In the event your data is held hostage by Ransomware, we recommend the following:


Remain calm. Rash decisions could cause further data loss

For example, if you discover an infection and suddenly cut power to a server, versus powering it down properly, you could lose data in addition to the infected data.


Never pay the ransom because attackers may not unlock your data

There are many cases of victims paying the ransom demanded and not receiving their data back in return. Rather than running this risk, companies should work with data recovery experts who may be able to regain access to data by reverse-engineering the malware.


Check your most-recent set of backups

If they are in-tact and up-to-date, the data recovery becomes easier to restore them to a different system.


Contact an expert to explore recovery options

An expert data recovery specialist will examine your scenario to see if they have a solution already in place; if not, they should be able to develop one in time.
