Malware may reinstall itself multiple times if you don't delete its core files. This may require tracking down dozens of files in different locations.
We recommend downloading Restoro to eradicate Malware for you (it should cut down the time to about 15 minutes).
What is Ultimo ransomware? And how does it execute its attack?
Ultimo ransomware, also known as “.Locked virus”, is a file-encrypting Trojan developed using the open source platform called HiddenTear. In other words, this ransomware Trojan is a new addition to the ever growing HiddenTear ransomware group. Ultimo ransomware executes its attack in a typical ransomware manner – it will scan the entire drive of the infected computer looking for certain file types such as:
.txt, .doc, .docx, .xls, .xlsx, .pdf, .pps, .ppt, .pptx, .odt, .gif, .jpg, .png, .db, .csv, .sql, .mdb.sln.php, .asp, .aspx, .html, .xml, .psd, .frm, .myd, .myi, .dbf, .mp3, .mp4, .avi, .mov, .mpg, .rm, .wmv, .m4a, .mpa, .wav, .sav, .gam, .log, .ged, .msg, .myo, .tax, .ynab, .ifx, .ofx, .qfx, .qif, .qdf, .tax2013, .tax2014, .tax2015, .box, .ncf, .nsf, .ntf, .lwp
Ultimo ransomware applies the AES encryption algorithm in encrypting files and appends the .locked extension on every affected file. Following the encryption, it delivers a ransom note demanding a ransom payment in exchange for the recovery of the encrypted files. Here’s the context of the ransom note contained in a file named “READ_IT.txt”:
“Oooopppsss Your Files Has Been Encrypted
Your Unique GUID for Decrypt: j43as8fk-29gp-61da-3671-h03c83472r74
SEND ME SOME 0.022 Bitcoin on Adress: 1CCnFhbLT1VSMUqXaSqsYUAwcGU4evkbJo
After Confirming The Payment, ALL YOUR FILES CAN BE DECRYPTED.
If you do not make payment within 48 Hrs, you will lose the ability to decrypt them.
Make your Bitcoin Wallet on: xxxxs://www.coinbase.com/ or xxxx://blockchain.info”.
How to buy /sell and send Bitcoin :
After the payment, enter the wallet from which paid, and email, in which contact you. firstname.lastname@example.org”,
After receiving the payment, we will contact you.”
The ransom note of this crypto-malware aims to blackmail victims into paying the demanded ransom as soon as possible by setting a time of 48 hours. But you have nothing to worry about and the only thing you should be rushing to do is to remove Ultimo ransomware. After you’ve accomplished that task, you can recover your encrypted files by using an alternative option provided later on this post.
