# Laboratorios CEFLO Allegedly Breached Exposing 21K Positive HIV, Syphilis, and COVID Test Results From the Mexican Lab

A threat actor describing themselves as specializing in “stealing medical data” claims to have breached Mexican clinical lab Laboratorios CEFLO, releasing the dataset for free out of stated retaliation after the lab allegedly ignored a paid pentest offer. The leak contains roughly 21,000 patient records flagged positive for HIV, syphilis (V.D.R.L.), COVID, and other tests, with samples showing full names, birth dates, and result types.
