Threat-actor claim — not a regulatory filing

This row is a claim by the ransomware group INC Ransom on its public extortion blog. It has not been validated by the victim or any regulator. Treat attribution and counts as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.

Post text · scraped from the leak site

Founded in 1862 as a patriotic society to support the Union and the policies of President Abraham Lincoln, The Union League of Philadelphia laid the philosophical foundation of other Union Leagues across a nation torn by civil war. The League has hosted U.S. presidents, heads of state, industrialists, entertainers and dignitaries from around the globe and has proudly supported the American military in each conflict since the Civil War. The Union League continues to be driven by its founding motto, Amor Patriae Ducit or Love of Country Leads.
