The party below shares a name or other identifying details with the entity on this page, but our research indicates it is a different party and is NOT the party named in the listing above.

  • Mikhail Pavlovich MatveevSeparately listed entityRU

    Also recorded as: Wazawaka · M1x · Boriscelcin · Uhodiransomwar

    A Russian national (b. 17 Aug 1992) wanted by the FBI and sanctioned by US OFAC under the online handle ‘Wazawaka’, in connection with ransomware operations.

    Why the mix-up: Shares the identical surname MATVEEV with the UK-listed RYBAR LLC content designer; a surname-only screen for ‘Matveev’ surfaces both as separate ProofAML corpus records.

    How to tell them apart:
    • Different given name and patronymic (Mikhail Pavlovich vs. the listed Maksim Vitalyevich) and a recorded DOB of 17 Aug 1992, vs. no DOB recorded for the listed individual
    • Wanted/sanctioned for ransomware-related cybercrime (FBI Most Wanted, OFAC SDN), unrelated to RYBAR LLC media activity
