The Roldat Ransomware is a file-encryption Trojan that is able to encrypt documents, images, archives, videos, spreadsheets and numerous other file formats. It Is likely that the file-locker is being propagated with the help of phishing emails that use basic social engineering tactics to trick the recipient into opening a malicious file attachment. Once the Roldat Ransomware is initialized on a computer, it may need a few minutes to complete the file-encryption task whose goal is to render the victim’s files useless.
The next step that the Roldat Ransomware takes is to rename all locked files by adding the ‘.roldat’ extension and then drop the ransom message ‘_readme.txt.’ The latter contains contact details, information about the attack, and instructions on what the victim has to do if they want to use their files again. Unfortunately, the proposal of the attackers is not acceptable – they want to be paid in Bitcoin in exchange for a decryption tool. However, there is zero proof that the decryptor exists or that they will provide you with it, so the offer might easily be a hoax.
Since you cannot rely on a free decryptor or ask the attackers for assistance, you are left with one choice – try alternative data recovery software. Unfortunately, these methods might not always work flawlessly, but you might be lucky enough to recover a small portion of your files. However, remember that your top priority is to eradicate the Roldat Ransomware with the use of an up-to-date anti-malware service.
