How to remove Basn Ransomware and decrypt .basn files

What is Basn Ransomware

Basn is a ransomware infection that targets various companies. Upon infiltration, it quickly scans the system for potentially important files (e.g., documents, databases, videos, images, etc.) and encrypts access to them. During this process, the virus also assigns its own .basn extension to highlight the blocked data. For instance, a file originally named 1.xlsx will change to 1.xlsx.basn and reset its icon to blank. Following successful encryption, the file-encryptor also drops a text file named unlock your files.txt with decryption instructions inside.

Inside the note, it is made clear that the victim’s data has been encrypted and extracted to cybercriminals’ servers. To unblock the encrypted data and prevent leakage of data to shady resources/figures, extortionists demand victims to pay a ransom in Bitcoin or Monero cryptocurrency. The price is not disclosed in the note as it is likely to vary depending on the amount and value of encrypted data. Unfortunately, unless the virus has severe vulnerabilities that could be exploited, cybercriminals are usually the only figures capable of decrypting access to data completely and safely. For now, no third party is known to be able to bypass the encryption applied by Basn Ransomware. The only available options for data recovery are to either collaborate with ransomware developers or obtain data from existing backup copies. Backups are copies of data stored on external devices such as USB drives, external hard drives, or SSDs. The only downside of self-recovery is that threat actors may indeed publish the collected data and therefore damage the reputation of some companies if they are actually intended to do so.

Using your own backups is considered safer than buying decryption from extortionists. Some cybercriminals fool their victims and do not provide any promised decryption tools/keys even after receiving the payment. It is highly advised to create regular and scheduled backups in order to ensure the majority of data can be recovered in the event of unexpected loss or ransomware affection. If no backups are present, you can try some third-party tools or attempt to recover from windows shadow copies. However, these alternatives may not always be effective and are only successful in rarely exceptional cases. Before starting manual recovery without the involvement of cybercriminals, it is crucial to delete the ransomware virus from your system so that it does not impact other files or spread to neighboring systems that are connected to the same network. On the other hand, even if you choose to collaborate with them to decrypt files, it is still important to remove the ransomware afterwards. Follow the steps in our guide to learn about ransomware removal and protect your system against such threats in the future.

How Basn Ransomware infected your computer

Many company-oriented infections get injected by exploiting various vulnerabilities in corporate networks or network storage systems like QNAP NAS, for instance. However, apart from this, other distribution channels are widespread as well – such are phishing e-mail letters, unprotected RDP configuration, infected software installers (pirated or cracked), trojans, fake updates/license cracking tools, unreliable ads, backdoors, keyloggers, and other dubious vectors. The main goal of these distribution techniques is to persuade users into downloading and opening some malicious file or link. For instance, fraudelent e-mails often disguise harmful attachments as legitimate and genuine files, such as .DOCX, .XLSX, .PDF, .EXE, .ZIP, .RAR, or .JS. Cybercriminals make such messages look legitimate by impersonating templates of trustworthy organizations (e.g., delivery companies, tax authorities, banks, and so forth).

Always maintain a high level of caution when dealing with content that could be potentially harmful. Avoid interacting with dubious download resources, torrent-sharing websites, suspicious ads, potentially malicious attachments/links, and other types of content that may find suspicious or compromised. To prevent drive-by installations of malware, make sure software is downloaded only from official and trusted resources.
