A ransom infection, attacking servers has been reported by malware researchers. The virus aims to slither onto the infected computer via a malicious file and it then encrypts important files on the server itself, adding the .allcry file extension to them. The malware then drops a ransom note, named “readme.txt” with a message asking victims to make a payoff in 0.2 BTC (BitCoins) to the wallet of the cyber-criminals. In addition to this, they leave an e-mail ([email protected]) for contact. If you are a victim of the Allcry ransomware virus, it is strongly recommended to read this article and learn how to remove this ransomware and restore files, encrypted by it on your server or PC.

How is Allcry Ransomware Spread
In order for it to be replicated, the Allcry virus may be sent to victims via e-mails of spamming character. Such e-mails are primarily created to deceive you into thinking they are legitimate messages from either a bank or a large retailer company. The messages have malicious e-mail attachments that are embedded within them and those attachments may pose as:
- Purchase receipts.
- Registration confirmation letters.
- Fake banking statements.
- Account activity reports.
As soon as the victim is tricked into opening the e-mails themselves, he or she immediately becomes infected.
Besides via e-mail, the Allcry ransomware can also arrive on a computer via other methods as well, such as:
- Fake license activators.
- Fake game patches/cracks.
- If it pretends to be an installer.
Also, the virus creates multiple connections to advertisement networks, suggesting it may arrive on your machine via adware as well.
Allcry Ransomware – Malicious Activity Analysis
Once an infection occurs, the ransomware begins to drop multiple different types of files on the computers of victims:
When these two files are dropped, the virus automatically creates a process in Windows Task Manager, called winsrv.exe. The process is located in the following folder:
To download the previously mentioned QBridge.exe file, the Allcry ransomware virus executes the following command in Windows Command Prompt, using functions, programmed in winsrv.exe:
→ ping 127.0.0.1 -n 3> Nul & copy% \QBridge.exe
The virus may use the same command to update or patch the QBridge.exe file. It’s legal alibi is that it is an ad module and it even has a valid digital signature to support that, suggesting this virus is created by someone with experience in signatures as well.
In addition to thos actions, the winsrv.exe file, created in the system folder has also embedded scripts with Keep-Alive type of connection to specific third-party hosts. The hosts are ad servers.
Allcry ransomware is also configured to drop it’s file encrypter in the following location:
The virus also creates registry entries with values for the allcry.exe file:
As soon as this is done, the Allcry ransomware also generates a script which automatically opens the “Allcry crypter” message each time you click to try and open an encrypted file. The message looks like the following:
Besides the main message which supports English, Korean and Chinese languages, another symptom of having this virus is it’s readme.txt ransom note file, which has the same message as the primary ransom note:
