EncryptHub has been linked to breaches affecting 618 organizations and is associated with the disclosure of two Windows zero-day vulnerabilities, CVE-2025-24061 and CVE-2025-24071, to Microsoft. The vulnerabilities were addressed during the March 2025 Patch Tuesday updates, and the reporter was acknowledged as 'SkorikARI with SkorikARI.' Investigations revealed a connection between EncryptHub and SkorikARI, following an incident where EncryptHub exposed their credentials. SkorikARI's accounts were used to report the vulnerabilities, contributing to Windows security. Evidence linking SkorikARI to EncryptHub includes password files exfiltrated from EncryptHub's system and a GitHub account associated with SkorikARI. EncryptHub has previously attempted to market zero-day vulnerabilities on underground forums and is believed to have affiliations with ransomware groups. The threat actor has executed social engineering campaigns, phishing attacks, and developed a custom infostealer known as Fickle Stealer. They created fictitious social media profiles and websites, such as a fake project management application called GartoriSpace, which installed malicious files on unsuspecting users. EncryptHub has also been implicated in exploiting a Microsoft Management Console vulnerability, CVE-2025-26633.
