How does CryptoLocker encrypt files?

CryptoLocker uses an RSA 2048-bit key to encrypt the files, and renames the files by appending an extension, such as, .encrypted or .cryptolocker or .[7 random characters], depending on the variant.

How does CryptoLocker work?

On execution, CryptoLocker begins to scan mapped network drives that the host is connected to for folders and documents ( see affected file-types ), and renames and encrypts those that it has permission to modify, as determined by the credentials of the user who executes the code.

Is CryptoLocker a ransomware?

CryptoLocker is by now a well known piece of malware that can be especially damaging for any data-driven organization. Once the code has been executed, it encrypts files on desktops and network shares and “holds them for ransom”, prompting any user that tries to open the file to pay a fee to decrypt them.
