ARROW Ransomware

ARROW ransomware is a malicious encryption-based virus that locks user files and demands a ransom in exchange for a decryption key. It adds the “.ARROW” extension to all affected files and creates a ransom note named GOTYA.txt in multiple directories. Victims are instructed to follow payment instructions through a Tor network site.

This ransomware is part of the notorious Dharma ransomware family, known for targeting individual users and enterprise systems alike.

ARROW Ransomware Overview

ARROW ransomware uses strong encryption algorithms to hold your files hostage. It changes the extension of locked files to .ARROW and places a ransom note directing the victim to a hidden payment site. Like other Dharma variants, ARROW ransomware does not specify the ransom amount directly in the note and instead refers victims to a Tor-based site for further instructions.

Threat Summary

Understanding ARROW Ransomware

How Did I Get Infected?

ARROW ransomware infections are typically caused by:

• Opening malicious email attachments or links
• Downloading pirated software or cracked applications
• Visiting compromised websites
• Exploiting outdated software vulnerabilities

Once the ransomware executes on your system, it silently encrypts your data and replaces file extensions with .ARROW.

What Does It Do?

Upon execution, ARROW ransomware:

• Scans the system for target file types
• Encrypts files using a strong algorithm
• Appends .ARROW to encrypted files
• Creates and drops a ransom note titled GOTYA.txt
• Instructs the user to visit a Tor-based payment portal

Encrypted files become unusable unless decrypted with a unique key held by the attackers.

Should You Be Worried?

Yes. ARROW ransomware is highly dangerous:

• It causes permanent file loss if backups are unavailable
• Paying the ransom does not guarantee file recovery
• It may lead to secondary infections or backdoor installations
• It targets both home and business users

The safest approach is to remove the ransomware immediately using a professional-grade anti-malware tool and avoid any interaction with the attackers.
