Qdla Virus – Main Activity
The .cool, .vtua and .palq viruses are just some of the variance that contain the same code as the Qdla ransomware. These infections typically propagate onto victims computers by using one of the two main strategies, shown beneath:
- In case you have downloaded it from some third-party websites offering freeware executables.
- If you have received it as an e-mail attachment or a link sent in a spam message.
In case of the first strategy being used, then there is a significant chance that the infection file mimics some sort of downloaded executable by the victim such as:
- Fake setups.
- Cracks or activators.
- Patches for apps or games.
- Portable software.
- Keygen (key generator activator).
Not only this, but we have also come across many cases of infected victim PCs via the virus file being sent to them as an email attachment, most often mimicking a very important document that is a “must see”, like:
