How to remove Foxtrot Ransomware and decrypt .foxtrot70 files

What is Foxtrot Ransomware

Discovered during a routine examination of malware submissions to VirusTotal, Foxtrot Ransomware is a nefarious variant from the MedusaLocker family. This ransomware encrypts files and appends the extension .foxtrot70 to the filenames, making previously accessible files inaccessible without the decryption key. Upon encryption, it generates a ransom note named How_to_back_files.html, which is placed in all affected directories. The note claims that files have been encrypted using a combination of RSA and AES cryptographic algorithms, a blend designed to thwart any decryption attempts without the attacker’s specific key. Victims are warned against using any third-party recovery software, as this would allegedly lead to permanent data corruption. Additionally, the note ominously states that confidential and personal data has been exfiltrated and will be released publicly unless the ransom is paid within 72 hours. To instill a semblance of trust, the attackers offer to decrypt a few non-sensitive files for free.

Despite these threats, paying the ransom is generally not advised. This is because attackers may not fulfill their promises, and paying them only fuels their malicious activities. As of now, there are no publicly available decryption tools specifically for .foxtrot70 files encrypted by Foxtrot Ransomware. Encryption algorithms like RSA and AES used by this ransomware are highly advanced, and only the attackers possess the decryption keys. However, those affected can use the ID Ransomware service to identify the ransomware and possibly find any related information or tools. Unfortunately, due to the robust nature of the encryption, decryption without the attacker’s key remains improbable. Preventative measures such as up-to-date antivirus software, cautious email practices, and regular backups on external or cloud storage are, therefore, the most effective ways to combat threats posed by ransomware like Foxtrot.

How Foxtrot Ransomware infects computers

Foxtrot Ransomware typically infiltrates computers through phishing emails that contain malicious attachments or links. These emails often disguise themselves as legitimate communications from trusted sources, tricking users into downloading and opening the infected files. Additionally, Foxtrot Ransomware can spread via compromised websites, malicious online advertisements, and pirated software obtained from unofficial sources. Once executed, the ransomware exploits vulnerabilities in the system to encrypt files and append the “.foxtrot70” extension to them. In some cases, it can also propagate through local networks by infecting connected devices, making it crucial to isolate the affected system immediately to prevent further spread.

2. Back up your files

As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. Foxtrot Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox

Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice. One of the world leaders in anti-spam protection is MailWasher Pro. It works with various desktop applications and provides a very high level of anti-spam protection.
