Coldcard Wallet Exploit Contagion Risk
The actual scope of the Coldcard incident may be larger than on-chain analysis can detect, as future attacks may not follow the same identifiable transaction fingerprint used in the initial compromise.
Too little corroboration in the last 3 days to call a trend (4 articles). Watching for it to gain traction.
Still mostly niche and specialist coverage — not yet picked up broadly by mainstream press.
"Stolen Bitcoin losses from the massive Coldcard wallet exploit have begun to slow, but the total amount of BTC swiped continues to climb—and the worst may not be over just yet... the final figure will likely be higher."
"TRM Labs also said that differences in transaction construction across each attack wave suggest multiple attackers behind the exploit. This is consistent with Galaxy's earlier findings that at least 15 different attackers may have exploited the Coldcard vulnerability."
"Early reporting pegged losses at roughly 594 BTC, or about $38 million, drained from around 500 wallets... the toll is now put at 1,196 addresses drained for about 1,082.65 BTC, or roughly $70.2 million, in a 41-minute window on July 30. That is nearly double the initial figure."
"Galaxy Research also cautioned that future attacks targeting Coldcard-generated addresses may not always follow the same on-chain 'fingerprint.' That means wallet owners should not assume that the first set of identifiable traits will be reused in later attempts."
