Aabn is file-encrypting ransomware that prevents regular access to your text files, Excel tables, videos and pics by ciphering them. It marks the encrypted files with the “.aabn” extension. Then Aabn ransomware adds a money ransom note (readme.txt) to each folder. In it, you can see the instructions to pay the ransom ($490-$980 in Bitcoin) to a certain Bitcoin address. The AES-256 or RSA-1028 cipher it utilizes to cipher the files is not decryptable with modern computers. Even quantum computers that currently exist will spend hundreds of years to find the decryption key.

How dangerous is the Aabn ransomware?

When Aabn ransomware gets in your system, it will scan your system for images, videos, and important documents. It encrypt] all widespread file formats- .psd, .doc, .docx, .xls, .xlsx, .pdf, .jpeg, .png, et cetera. When these files are located, the ransomware will cipher them and change their extension to “.aabn” to ensure that you understand what happened.

After the Aabn ransomware ciphered the data on your PC, it will generate the last “readme.txt” file on the main screen. Besides the money transferring instructions, the victims also see the email addresses to contact the cybercriminals – helprestoremanager@airmail.cc and manager@mailtemp.ch.

How did the Aabn ransomware get on my computer?

The Aabn ransomware spreads by placing links to download hacked programs or games. Cybercriminals that spread this ransomware are pretty clever, and try to keep in touch with modern things. New games releases, new popular films – Aabn creators make whatever to get their victims on that. Some of the most popular methods these crooks use is one-day sites with torrent downloading links. However, using the contemporary trends is not the only manner these crooks utilize. Options that have already become classic, such as e-mail spamming, are likewise common for STOP/Djvu ransomware spreading.

Malicious email spam
The example of email spamming that may lead to Aabn ransomware injection

Preventing this ransomware does not require a lot of initiative. Following the regular principles of PC hygiene will significantly decrease all hazards. Keep in mind that opening all files you receive on e-mail is not a good habit. Even worse case is to allow macros in Microsoft Office files. But it is much better to prevent the malware attack at the moment when you have just opened the e-mail message. Inspecting the sender’s address can point out a lot about what you can anticipate, and also when you see things like “support@amazon.com”– it is likely a genuine e-mail. At the same time, stuff that tries to look like Amazon or FedEx shipment alert, but uses the e-mail address of “amazonspurrot1363@gmail.com”– must make you be on the alarm. Above, you can see the illustration of such a message.

Outlaw sources of different digital things require some additional explanation. Breaking copyright law already exposes you to the possibility of being fined. Nevertheless, utilizing torrent trackers or third-party sites to download “free” programs also exposes you to various malware. Nobody can control anonymous people that start the torrent seeding or publish the hacked program version on the website with pirated software.
