A ransomware group calling itself Qilin claims to have carried out an attack against Thrifty Building Supply, with the claim dated August 19, 2026. This listing was tracked by ransomware.live, a security research platform that monitors ransomware groups’ public leak sites, on the group’s own extortion portal.

What we know — and don’t
- The claimed date of the alleged attack is August 19, 2026, according to the group’s leak-site listing.
- Thrifty Building Supply operates in the ‘other’ sector as categorized for this report, outside the standard finance, legal, education, retail, or healthcare classifications.
- The specific types of data the group claims to have obtained have not been disclosed in the listing and have not been confirmed by the company or any regulator.
- No official statement from Thrifty Building Supply or any government/regulatory body has been issued confirming or denying this claim as of this writing.
- Ransomware groups frequently exaggerate or fabricate claims to pressure victims, so this listing alone should not be treated as proof of a breach.
