EncryptHub, a lone figure shrouded in controversy, has been credited by Microsoft for reporting two Windows security flaws. However, his involvement in cybercrime soon became apparent, raising questions about the blurred lines between cybersecurity and illicit activities.
Pierluigi Paganini analyzed the persona of EncryptHub, revealing a complex individual torn between cybercrime and legitimate security research. EncryptHub was born in Ukraine, where he spent his formative years before fleeing to Romania and settling near the border. He resumed freelance development after jail but struggled financially, leading him to pivot towards cybercrime in 2024. EncryptHub reported two Windows security flaws to Microsoft, CVE-2025-24061 and CVE-2025-24071. MICROSOFT ADRESSED these vulnerabilities with Patch Tuesday updates in March 2025. EncryptHub exhibited major OPSEC mistakes, such as reusing weak passwords and leaving critical files exposed. He used ChatGPT to generate forum posts, statements, and translate emails and messages.
In the vast expanse of the dark web, a lone figure emerged, shrouded in mystery and controversy. The alias "EncryptHub" had become synonymous with a plethora of cybercrimes, from vishing and ransomware to malware and vulnerability research. However, beneath this seemingly monikered identity lay a complex individual, torn between the allure of illicit activities and the pursuit of legitimate security research.
Pierluigi Paganini, a renowned cybersecurity expert, shed light on the persona of EncryptHub through a detailed analysis published by Outpost24 KrakenLabs. The report revealed that EncryptHub was born in Ukraine, where he spent his formative years before fleeing to Romania and later settling near the country's border.
Following a decade of low-profile IT work and self-study, EncryptHub's activities paused in 2022, likely due to a stint in jail. Post-release, he resumed freelance development but struggled financially, ultimately forcing him to pivot towards cybercrime in 2024. This marked the beginning of a tumultuous journey that would see him oscillate between legitimate security research and illicit activities.
Notably, EncryptHub's exploits were attributed to Microsoft, which credited the individual for reporting two Windows security flaws. The first vulnerability, CVE-2025-24061, pertained to the Mark-of-the-Web (MOTW) Security Feature Bypass Vulnerability, where an unauthorized attacker could bypass local protection mechanisms. The second, CVE-2025-24071, exposed sensitive information in Windows File Explorer, allowing spoofing over a network.
Microsoft addressed these vulnerabilities with the release of Patch Tuesday security updates for March 2025, underscoring the significance of EncryptHub's findings. However, his involvement in cybercrime soon became apparent, as he repeatedly exhibited major Operational Security (OPSEC) mistakes. These transgressions included reusing weak passwords across accounts, failing to enable or secure two-factor authentication, mixing personal and criminal activities, and leaving critical files exposed on poorly secured servers.
Furthermore, Telegram bot misconfigurations allowed investigators to infiltrate his groups, while testing malware on his own systems resulted in the leakage of personal data and credentials. The most recent exploit of a Microsoft Management Console zero-day, CVE-2025-26633, was used by EncryptHub to deploy info stealers and new backdoors, SilentPrism and DarkWisp.
In a surprising turn of events, EncryptHub has been observed using ChatGPT as a writing assistant for tasks such as translating emails and messages, as well as entire conversations and negotiations with other TAs and potential clients. He has also leveraged the AI-powered tool to generate forum posts and statements.
On March 11th, 2025, the same day that Microsoft released the two CVEs attributed to EncryptHub, he announced his intention to sell some of his exploits on the Russian-speaking forum xss[.]is. To facilitate this, EncryptHub utilized ChatGPT's response to identify relevant CVEs, including CVE-2025-26633 and CVE-2025-24983.
In conclusion, the enigmatic figure of EncryptHub serves as a poignant reminder of the blurred lines between cybersecurity and cybercrime. As his exploits continue to captivate the attention of researchers and law enforcement agencies alike, it remains to be seen whether he will reconcile his dual identities or succumb to the allure of illicit activities.
