blackbastaThis record tracks a ransomware attack claimed by the blackbasta group against hallidays.co.uk. 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
hallidays.co.uk is a UK-based business site associated with Hallidays Group, a firm of accountants and business advisers. Public company and directory records describe the group as operating from Stockport, England, and offering services such as audit, accounts, payroll, corporate finance, corporate recovery, tax, and VAT advice. The Hallidays brand presents itself as a professional services provider rather than an energy operator, so the energy-sector tag should be treated as the catalog classification for this listing. It was listed as a ransomware victim associated with blackbasta.
