Disclosure context

About MYDATA / ALPHA LOCKER

MYDATA / ALPHA LOCKER is an emerging ransomware group first observed in May 2026 with financial extortion as its primary motivation, currently representing a nascent threat actor with a very limited publicly documented operational history. Given the extremely limited public reporting available from authoritative sources such as CISA, the FBI, Mandiant, or established security research organizations, the group's origin, affiliation, and infrastructure details remain largely unattributed and unconfirmed at this time. Based on available victim telemetry, the group has targeted at least one organization in Greece with a focus on the manufacturing sector, suggesting either opportunistic targeting or early-stage sector-specific reconnaissance, though no definitive attack methodology, initial access vectors, or encryption tooling details have been publicly documented to a verifiable standard. No notable high-profile campaigns, record ransom demands, or law enforcement actions have been publicly attributed to MYDATA / ALPHA LOCKER as of the time of this assessment. The group appears to be in its earliest operational phase, and its current status, including whether it operates as a Ransomware-as-a-Service model or as an independent closed group, cannot be confirmed without additional corroborating intelligence from authoritative sources; continued monitoring is warranted given its recent emergence. The group has been linked to 14 public disclosures across our corpus. First observed on a leak site on May 14, 2026; most recent post May 29, 2026. The operation is currently active.
