BPTO Ransomware. How to decrypt .bpto files?

Written by William Reddy

If you can’t open your photos, documents, or data and also see the .bpto extension on them, your computer is definitely infected with Bpto ransomware. It belongs to STOP/Djvu ransomware group

Bpto ransomware encrypts personal files located on the victim’s computer with the extension “.bpto” and then leaves the ransom note in each folder which contains encrypted files. The instructions are placed on the victim’s PC in the “readme.txt” file. Its task is pretty much similar to other variants of the same ransomware family: Bpsm, Znws, Znto.

Bpto is file-encrypting ransomware that prevents regular access to your text files, Excel tables, videos and pictures by encrypting them. It marks the ciphered files with the “.bpto” extension. Then Bpto ransomware adds a money ransom note (readme.txt) to each folder. In this note, you can see the guidance to pay the ransom ($490-$980 in Bitcoin) to a specified Bitcoin wallet. The AES-256 or RSA-1028 cipher it uses to cipher the files is not decryptable with contemporary computers. Even quantum computers that already exist will spend hundreds of years to find the decryption key.

How dangerous is the Bpto ransomware?

When Bpto ransomware appears on your PC, it will check your disks for photos, videos, and important documents. It [ciphers all widespread file formats- .psd, .doc, .docx, .xls, .xlsx, .pdf, .jpeg, .png, et cetera. When these documents are located, the ransomware will cipher them and change their extension to “.bpto” to ensure that you understand what happened.

After the Bpto ransomware encrypted the data on your PC, it will generate the last “readme.txt” file on the main screen. In addition to the ransom payment instructions, the victims also see the emails to contact the crooks – datarestorehelp@airmail.cc and support@fishmail.top.

How did the Bpto ransomware get on my computer?

The Bpto ransomware spreads by placing websites to download hacked programs or games. They try to keep their eye on all hype themes which can be chosen to spread ransomware. New games introductions, new popular movies – Bpto creators make everything to get their victims on that. Some of the most popular methods these crooks apply is one-day websites with torrent downloading links. However, pursuing the contemporary news is not the single way these criminals use. Ways that have already become standard, such as e-mail spamming, are likewise ordinary for STOP/Djvu ransomware spreading.

Malicious email spam

The example of email spamming that may lead to Bpto ransomware injection

Avoiding this ransomware does not need a lot of effort. Following the ordinary principles of PC hygiene will substantially decrease all dangers. Keep in mind that opening all documents you get on e-mail is not a great tactic. Even worse situation is to allow macros in Microsoft Office documents. However, it is much better to avoid the malware intrusion at the moment when you have only opened the email message. Checking the sender’s address can say a lot about what you can expect, and also when you see the thing like “support@amazon.com”– it is likely a genuine e-mail. At the same time, stuff that tries to appear like Amazon or FedEx shipping alert, but uses the e-mail address of “amazonspurrot1363@gmail.com”– must make you get on the alarm. Above, you can see the illustration of such a message.

Outlaw sources of various digital things need some extra explanation. Going against copyright law already exposes you to the risk of being fined. Nevertheless, using torrent trackers or third-party websites to download “free” programs also exposes you to various malware. No one can regulate unnamed people who launch the torrent seeding or release the hacked program version on the site with pirated program.
