Cybercriminals are taking deception to new heights by impersonating the infamous Cl0p ransomware gang to extort money from businesses. Recent investigations by Barracuda Networks have uncovered a disturbing trend where fraudsters send fake extortion emails, falsely claiming to have infiltrated company networks and stolen sensitive data.
The Rise of Ransomware Impersonation
This tactic preys on the fear and notoriety surrounding major ransomware groups. Scammers craft emails that mimic the language and threats used in real cyberattacks, referencing publicly known vulnerabilities exploited by actual ransomware gangs to appear credible.
For instance, one extortion attempt cited Cl0p’s exploitation of a Cleo software vulnerability, which was reported by Hackread.com in December 2024. By using such references, scammers trick businesses into believing they are the next victim of a high-profile attack—pressuring them into paying ransom demands.

Beyond Digital: Physical Ransomware Letters
Shockingly, this impersonation scam isn’t confined to email. Earlier reports revealed that fraudsters posing as the BianLian ransomware gang mailed fake ransomware letters to businesses across the United States via the US Postal Service. This old-school tactic adds another layer of credibility, making victims more likely to fall for the scam.
Weaponizing Phishing Kits & File Formats
Beyond impersonation, cybercriminals are leveraging advanced phishing tools to enhance their attacks. Kits like FishXProxy and Telekopye allow even amateur scammers to create realistic phishing pages that mimic legitimate login portals. These pages dynamically adapt to user input and integrate with multiple communication channels, making them difficult to detect.
Additionally, attackers are exploiting Scalable Vector Graphics (SVG) files to deliver malware. These files contain embedded scripts that often slip past security tools, providing hackers with a stealthy method to compromise systems.
How to Stay Protected
With cybercriminals adopting more sophisticated and deceptive tactics, businesses must:
- Verify extortion claims – Before responding, conduct thorough cybersecurity checks.
- Enable multi-factor authentication (MFA) – Strengthens security against phishing attacks.
- Monitor for unusual activity – Be wary of unsolicited emails referencing known cyber threats.
- Educate employees – Training staff to recognize phishing attempts can prevent breaches.
As scammers continue refining their tricks, staying vigilant and proactive is the best defense. Not every threat is real—but falling for the wrong one can have real consequences.
