blackbastaThis record tracks a ransomware attack claimed by the blackbasta group against GRUPO mh. It collects the publicly disclosed attack details — sector, location and timeline — as published on the operator's leak site and indexed by Breach House.
Window Zero
EXPOSURE GAPWindow Zero is the time the breach stayed in the open before anyone said so — the gap between when the attack was first discovered on the operator's leak site (t1) and when it was publicly disclosed (t2). The wider this window, the longer victims, staff and customers were exposed with no warning.
Attack Summary
grupmh.com appears to be a Spanish business in the broad Other sector, but the available public record does not clearly identify its exact line of work. Based on the name alone, it can only be described conservatively as a company operating from Spain, without adding unverified details about products or services. In threat-intelligence catalogs, it is indexed as a ransomware victim entry tied to BlackBasta. The listing notes it as a ransomware victim associated with blackbasta.
