ShinyHunters claims it hijacked rival cybercrime group cl0p’s dark-web site.

Digital-extortion group ShinyHunters told Reuters it exploited a vulnerability in rival gang cl0p’s software and gained broad control of its infrastructure. Cl0p’s site was unreachable on Sunday after displaying a seizure message attributed to ShinyHunters on Saturday; cl0p did not respond to requests for comment.

Two cybersecurity specialists said the confrontation appeared genuine, but Reuters could not independently establish the full account. ShinyHunters said the dispute grew from an alleged theft of a previously unknown Oracle E-Business Suite exploit later used by cl0p against more than 100 companies.
