Full Bio. Here's the explanation: We recently started getting reports from infected victims, analysed a sample, and added detection for Gpcode. In the text file the criminal tells the victims that the file has been encrypted and offers to sell them a "decryptor": «Your files are encrypted with RSA algorithm. To recovery your files you need to buy our decryptor. My Profile Log Out. Join Discussion for: Blackmail ransomware returns with bit Add Your Comment.

The job of the Trojan is usually to establish a remote connection with a host file, which distributes the public keys used. One of the keys is left on the infected computer, to be later used by the owner if he decides to pay for the ransom. Why is Ransomware so difficult to detect? As we already mentioned above, one of the main reasons why this particular kind of harmful software is so dangerous is because it very often remains undetected until way too late.

This all has to do with the unique and devious agenda of typical Ransomware compared to other types of viruses. RSA and most other Ransomware programs use an encryption to lock your files. While the code makes you unable to access your files, it is not inherently malicious. Many legit programs actually use encryption for their files.

This is also where the ransom part comes into play. After the virus has locked your data, it displays a message on your screen that demands a ransom payment in return for the decryption key. Instructions on how to send the money to the blackmailer are usually provided to ensure that everything goes according to the demands of the hacker. In the majority of cases Ransomware hackers require their ransom in bitcoins. This is a cryptocurrency that is basically untraceable. This leaves the cyber-criminal in full anonymity during and after the money transfer.

This makes fighting hackers that use Ransomware viruses that much more difficult and is also one of the main reasons why programs using the RSA algorithm are becoming so popular at such a rapid pace. Furthermore, the more widely spread Ransomware becomes, the more effort is put into improving the newer virus versions making them even more difficult to handle. Manual detection.

Maybe your anti-virus cannot detect the encryption process. However, it is possible that you can do that manually, by being vigilant and noticing any strange PC behavior that may occur. This is because RSA needs some time to encrypt your data and often requires considerable amounts of system resources.

In fact, once the virus gets inside your PC, it first needs to make a copy of all targeted files — those copies are actually the ones locked by the encryption. Still, the time and resources this process requires might give you the opportunity to intercept it.
