Hackers leaked documents claiming Belarusian universities in Grodno Region are preparing to house around 900 mobilized reservists, indicating possible militarization near Poland and Lithuania borders.

On 21 July 2026, the Ukrainian hacker group '256th Cyber Assault Division' published leaked internal documents dated late June 2026 indicating that three Belarusian educational institutions in the Grodno Region—Grodno State Agrarian University, Grodno College of Economics and Management, and Lida State Music College—are preparing to temporarily accommodate mobilized reservists, totaling approximately 900 personnel. The documents reveal requests for military accommodation logistics such as folding beds, mattresses, hygiene and cleaning supplies. These preparations are assessed as part of a militarization effort in Belarus’s border areas adjacent to Poland and Lithuania, raising concerns over increased military readiness near NATO borders. There has been no official confirmation from Belarus, though Ukraine has noted ongoing military infrastructure expansion near its border with Belarus. Belarusian leadership denies direct military engagement against Ukraine. NATO officials caution that Belarus remains under strong Russian influence, implying that Belarusian actions are significantly shaped by Kremlin directives. This development is analyzed as a hybrid warfare indicator given the mixing of civilian infrastructure use for military purposes in a contested geopolitical environment.
