Adventurer Ransomware

Adventurer ransomware is a dangerous crypto-virus that locks victims’ files by appending the .adventurer extension and delivers a ransom demand named README.TXT. This malware spreads through infected email attachments, torrent sites, pirated software, malicious ads, and tech support scams. Victims cannot access their files without a decryption key, making it a serious cybersecurity threat.

YOUR FILES ARE ENCRYPTED
Your files, documents, photos, databases and other important files are encrypted.
You will not be able to decrypt it yourself! The only way to recover your files is to buy a unique private key.
Only we can give you this key and only we can recover your files.
To make sure that we have a decryptor and it works, you can send an email to: and decrypt one file for free. But this file must not be of any value!
Do you really want to recover your files? MAIL: adventurer@mailum.com

Attention!

• Do not rename encrypted files.
• Do not try third-party decryptors—they may corrupt your data or increase ransom.
• We’ve been in your network long—we have your data. Delay and we’ll begin phase two.

Detailed Threat Evaluation

How I Got Infected

Adventurer can infect systems through everyday behavior like opening malicious email attachments, downloading cracked software from torrent sites, clicking deceptive ads, or falling victim to tech support scams. Once it’s inside, it encrypts files silently in the background.

What It Does

The ransomware locates documents, pictures, and other files, encrypts them using strong algorithms, and changes their names to filename.{unique ID}.adventurer. After encryption, it drops the README.TXT ransom note, blocking access and threatening public data leakage. It may also install additional malware to steal credentials or spread further.

Should You Be Worried?

Absolutely. The encryption is strong and there’s no known free decryptor available. Victims are coerced into paying with a ticking 24-hour deadline, with threats of blackmail and further damage. Even if you pay, there are no guarantees of file restoration. Plus, the malware may lurk on your system, ready to strike again.

Conclusion

Adventurer ransomware is a potent cyber threat: high-encryption, aggressive blackmail tactics, real-time network infiltration, and strong pressure tactics. Recovery without backups or paying (which is not recommended) is virtually impossible. Prioritize scanning your system with SpyHunter to fully remove the infection, and restore data only from secure, clean backups.
