On September 16, 2026, Odyssey Charter School, Inc. was listed as a victim on the WALLSTREET ransomware group's leak site, marking a potential ransomware attack. The listing lacks details on whether data was encrypted or exfiltrated. Similarly, on the same day, ARDA, a public-sector organization in the government and defense sector, was also listed on a ransomware leak page, but no specifics regarding the attack method or ransom demands were provided. Prior to this, on September 12, 2026, the Namibian Defence Force was listed on the RANSOMHOUSE leak site, again with no details on the attack's scope or impact. All three incidents are currently unverified claims, with insufficient information to assess the operational impact or confirm the attacks. The lack of corroborating evidence means these claims should be treated with caution until further information is available.
