Cryptobot Virus – Removal Instructions
Cryptobot is a ransomware virus that was especially made to attack computers that run Microsoft Windows. It was first noticed by Dell back in September of 2013. Ransomware is a malware that takes infected computers hostage and involve a request for some form of payment. Cryptobot was spread through email attachments carrying infection, and through an already existing botnet. When it is activated, the virus encrypts particular kinds of files kept on network drives utilizing cryptography that is RSA public-key. The Cryptobot virus then shows a message offering the decryption of the data on the condition that a payment is made by a dictated deadline, and threated to delete the private key (stored on the malware’s control servers) if the deadline passes.
In the event that the deadline is not met, the Cryptobot malware offered to decrypt data through an online service provided b the operators of the malware, for a much higher price in Bitcoin. Cryptobot successfully garnered millions of dollars in ransom payments, especially during the first two months of its distribution. Through a survey, researchers at the University of Kent determined that 41% of British victims of Cryptobot decided to pay the ransom, a figure much greater than expected, including conjectures of 3% and 0.4% by Symantec and Dell SecureWorks, respectively.
Cryptobot was typically sent and spread in the form of an attachment to a message that was seemingly harmless, appearing to be sent by a legitimate company. A ZIP fie attached to a message contains an executable type of file with the icon and filename in the disguise of a PDF file, tricking Windows by its default behavior of keeping the file name extension hidden from file names to cover up the real extension, EXE. The Gameover ZeuS botnet and trojan was another way Cryptobot was spread.
When the Cryptobot is first used, the body data places itself in the user profile folder, adding a key to the registry that makes it run on the computer’s startup. Next, Cryptobot attempts to contact one of several designated control and command servers: once a connection has been established, the server generates a RSA key pair, and the public key is sent back to the infected computer. The server may be a local proxy, going through others, frequently undergoing relocation in different countries to increase the difficulty of tracing them.
