How Crypto24 Infects and Encrypts Files?
Once activated, Crypto24 ransomware begins encrypting files, targeting documents, images, databases, and more. It adds the .crypto24 extension to encrypted files—for example, report.docx becomes report.docx.crypto24—making them unusable. Alongside encryption, the ransomware drops a ransom note named “readme.txt” in affected folders, confirming the attack.

The Ransom Note and Communication Process
After encrypting files, Crypto24 leaves a “readme.txt” note with instructions for contacting the attackers and paying the ransom. The note typically includes:
- An email address or a link to a secure messaging platform
- A unique victim ID for identification
- Threats of permanent data deletion or increased ransom demands if payment isn’t made within a set deadline
Detection and Technical Insights
Security researchers have identified Crypto24 under various detection names, highlighting its complexity and possible ties to other malware strains:
- Avast: FileRepMalware [Misc]
- Fortinet: W32/PossibleThreat
- Kaspersky: Backdoor.Win32.Mokes.atbt
- Microsoft: Trojan:Win32/Wacatac.B!ml
- Symantec: Packed.Generic.143
These classifications suggest Crypto24 may share traits with other malicious programs, making it a versatile and dangerous threat.
How Crypto24 Spreads?
The ransomware uses multiple infection methods, including:
- Phishing Emails – Malicious attachments or links in deceptive emails
- Remote Desktop Protocol (RDP) Attacks – Exploiting weak RDP credentials
- Software Vulnerabilities – Targeting unpatched security flaws
- Malicious Ads & Websites (Malvertising) – Drive-by downloads from compromised sites
Prevention Strategies
To defend against Crypto24, organizations and individuals should:
✅ Be cautious with emails – Avoid opening suspicious attachments or links
✅ Secure RDP access – Use strong passwords, enable 2FA, and restrict access to trusted IPs
✅ Keep software updated – Patch OS and applications to close security gaps
✅ Maintain backups – Store critical data offline or in secure cloud storage
✅ Use strong security software – Deploy anti-malware with real-time protection
✅ Train employees – Educate staff on phishing and safe browsing habits
What to Do If Infected?
If Crypto24 strikes:
- Isolate the infected device – Disconnect it from networks to prevent spread
- Consult cybersecurity experts – Professionals may help assess damage and explore decryption options
- Avoid paying the ransom – No guarantee of recovery, and it fuels further attacks
- Restore from backups – The safest way to recover encrypted files
For malware removal, tools like Combo Cleaner Antivirus for Windows (by RCS LT) can help detect and eliminate ransomware.
