Galaxy Research, in analysis tracked by Bitcoin News, said groups exploiting weaker COLDCARD seed security showed distinct operating patterns. The research said the 10 largest groups alone moved roughly 1,700 BTC, with the biggest single group accounting for more than 1,080 BTC. Researchers differentiated the attackers by looking at fee strategy, transaction timing, consolidation patterns, and where the stolen bitcoin was sent. The findings also said several of the largest groups still appear to hold nearly all of the stolen BTC. The notice added that victims affected by the COLDCARD attacks can contact @intangiblecoins for help gathering evidence and reaching relevant authorities. The report did not disclose additional details beyond those indicators, but it framed the activity as organized into multiple clusters rather than a single actor.
