What is x1881?

Found by Malware Hunter Team, x1881 is another version of a well-recognized ransomware infection called CryptoMix. Once on the system, this malware encrypts all the documents and would lock all the information and rename the file extensions utilizing the "[32_random_letters_and_digits].x1881" design. For example, "sample.jpg" may be renamed to a filename, for example, "00A9531D13E7B26BC7E3A84F1414E6AB.x1881". Once the encryption is successful, x1881 leaves a text document with the ransom note in all the encrypted folders.

 The folders that were encrypted will now have a new text document named "_HELP_INSTRUCTION.TXT." This new document contains a message demanding ransom from the victim for the decryption key and details on how to pay the ransom through cryptocurrency. At this point, the victims are already running on a deadline. If the ransom is not paid on time, the consequences can be harsh either the amount would be raised, or the user might lose his data. As per the latest update from the researchers, it is still unknown whether x1881 utilizes symmetric or Hilter kilter cryptography. In the two cases, decryption requires a decryption key of its kind. Cybercriminals store this key on a remote server and urge the victim to make the payment in the ultimate deadline, or the decryption key will be destroyed, and then no one would be able to retrieve their data. For now, there is no standard amount, designers of this type of ransomware infections ordinarily request something between $500 and $1500 in Bitcoins. No matter if the demanded amount is very less, never pay - As per the records a user once attacked has been under attack several times even after paying the ransom. There is a high possibility that you will be duped again- paying won't result in any positive outcome. Also, you will support digital offenders' organizations. Never endeavor to contact these individuals or pay any payoffs. Shockingly, at present, there is no program capable of decrypting x1881 ransomware, and the only way to retrieve your data is through the backup.

There are many ransomware infections equal to x1881. The rundown of cases incorporates (yet isn't constrained to) Blind, My Decryptor, Anubis, ZONEware, and Striked. In spite of the fact that, various cyber criminals create these infections, the end result is same- they encrypt and lock away information and make demands to release them. The main significant difference is the ransom amount that is to be paid and the kind of encryption algorithm utilized. Sadly, most utilize algorithm, (for example, RSA, AES, etc.) that create one of a kind decryption keys. Along these lines, unless the malware contains bugs/defects (for instance, stores the key locally) or isn't wholly created, reestablishing records physically (without the help an IT expert is not recommended) is nearly impossible. Therefore, x1881 and other such ransomware infections present a strong case for maintaining regular data backups.

How did x1881 ransomware infect your computer?

 To distribute x1881 ransomware hackers usually utilize spam emails (irresistible attachments), third-party programs, third-party websites, freeware programs, freeware games, and trojans.
