Ragnar Locker is a household of ransomware, which first got here to prominence in early 2020 when it grew to become infamous for hitting massive organisations, making an attempt to extort massive quantities of cryptocurrency from its victims.
So simply your bunch of cybercriminals then?
Sure, though on their underground web site, the place they leak information stolen from their company victims, they try and painting themselves somewhat otherwise.
Within the Ragnar Locker gang’s “About us” part they make the somewhat unconvincing declare that they “don’t pursuit goal to make enormous injury to anybody’s enterprise”, while admitting that “if it might be obligatory, little question we are going to do what we promise and the implications might be disastrous.”
The criminals even try and persuade their victims that they will help enhance safety:
“We’re fascinating to find weaknesses and vulnerabilities in networks and we’re good at this, we will help to enhance the safety measures, that’s why we give an opportunity to make a deal and offering listing of suggestions and penetrations reviews.” “Firms below assault of Ragnar_Locker can rely it as a bug looking reward, we’re simply illustrating what can occurs. However don’t neglect there are a whole lot of peoples in web who don’t need cash – somebody would possibly need solely to crash and destroy. So higher pay to us and we are going to allow you to to keep away from such points in future.”

authorities, and data expertise sectors, says the FBI.

May that point out what a part of the world the ransomware originates from?
You would possibly assume that, I couldn’t probably remark. However it’s typically believed that some cybercriminal gangs intentionally keep away from hitting corporations in their very own nation, within the hope of avoiding undesirable curiosity from native regulation enforcement companies.
Gotcha. So when the Ragnar Locker ransomware triggers – what does it encrypt?
What’s maybe faster to explain is what it doesn’t encrypt. As a way to permit the pc to function “usually” in the course of the encryption course of, it avoids encrypting information within the following folders on the C: drive:
- Home windows
- Home windows.previous
- Mozilla
- Mozilla Firefox
- Tor browser
- Web Explorer

- Program Knowledge
- Opera
- Opera Software program
As well as, when biking by information, Ragnar Locker ignores information with the next
extensions:
- .db
- .sys
- .dll
- .lnk
- .msi

- .exe
After all, these are all filetypes that may usually be simply changed – not like information information which usually carry better worth.
However to encrypt information it must have discovered its means into your organisation someway. How does it do this?
The Ragnar Locker gang is like many different cybercriminal teams focusing on companies with ransomware – profiting from internet-exposed providers reminiscent of RDP, brute-forcing passwords or utilizing stolen credentials. As soon as in, an attacker will try to realize better privileges and transfer laterally all through the community.

If my firm has fallen sufferer to Ragnar Locker, ought to we pay the ransom?
