JETS

Attackers reached part of the internal administrative systems at JETS, operator of Jamaica's MultiLink and ACH networks, where the names of some ACH recipients and debit card numbers sat in historical administrative files that may have been exposed. The source gives no entry point, no actor, no count, and no window. The payment networks were walled off well enough to hold. The exposure lived in the archive, where card numbers were kept on the administrative side of the wall.
