www.css.org.pa https://www.zoominfo.com/c/caja-de-seguro-social/455482072 www.css.gob.pa Caja de Seguro Social (CSS), the Panamanian Social Security Fund. The CSS is a public institution responsible for administering and governing the national social security and healthcare system in the Republic of Panama. Manages a network of hospitals and clinics nationwide, serving approximately 84% of Panama's population. 3TB of data, including pension, medical, and investment data. As gentlemen, we offered to pay a fair price for the mistake made, after which all data would be permanently deleted from our servers. The management decided that their influence on public opinion is so strong that the incident will remain unnoticed, so we are forced to publish proof of the hack and put the medical and pension databases containing 80% of Panama's population up for sale as a single package for 2 BTC.
