A new ransomware campaign targeting individuals and organizations in the UK and the US has been identified.
The attack, known as the “Prince Ransomware,” utilizes a phishing scam that impersonates the British postal carrier Royal Mail.
This campaign highlights the growing sophistication of cyber threats and the need for heightened vigilance among internet users.

The Attack Methodology
Researchers at Proofpoint first detected the Prince Ransomware campaign in mid-September.
The attack method is insidious, involving contact forms on target organizations’ websites rather than traditional email phishing methods.
This approach allows attackers to bypass some email security measures and reach multiple recipients within an organization.

The attackers send messages that appear to originate from a Proton Mail address, masquerading as official communications from Royal Mail.
These messages contain a PDF attachment that directs victims to download a ZIP file from Dropbox.
This ZIP file contains another password-protected ZIP file and a text file with the password needed to open it.
Once opened, the second ZIP file contains a shortcut (LNK) file that executes JavaScript code designed to deploy the ransomware.
The ransomware encrypts files on the victim’s computer, adding the “.womp” extension, and displays a ransom note demanding payment in Bitcoin for decryption.
A Destructive Outcome
This campaign lacks a decryption mechanism, unlike typical ransomware attacks, which aim to extort money in exchange for decrypting files.
The ransom note falsely claims that files have been exfiltrated and promises automatic decryption upon payment of 0.007 Bitcoins (approximately $400).
However, there is no capability for data exfiltration or victim identification, suggesting that even if victims pay, their files will remain inaccessible.
The attack’s destructive nature raises questions about its motives. It is unclear whether the threat actors made a mistake or intentionally designed to disrupt without financial gain.
The lack of communication instructions supports the theory that decryption was never intended.
Implications and Preventive Measures
The Prince Ransomware campaign underscores the importance of cybersecurity awareness and preparedness.
Organizations are advised to educate their employees about recognizing phishing attempts and suspicious communications, especially those involving unexpected attachments or requests for sensitive information.
Additionally, organizations should implement robust security measures such as multi-factor authentication, regular software updates, and comprehensive data backup strategies.
These steps can help mitigate the impact of ransomware attacks and ensure business continuity.
The open availability of Prince Ransomware on platforms like GitHub also highlights a broader issue within cybersecurity: the accessibility of malicious tools for educational purposes that threat actors can easily repurpose.
This calls for stricter regulations and monitoring of open-source repositories to prevent misuse.
