Look at all the fleeced crypto idiots, say the people holding lots of cryptocurrencies (and who themselves have been robbed, rug-pulled or scammed multiple times over the years). The crypto noobs are doing it all wrong, they say: The only safe way to store your crypto wealth is in an offline hardware wallet that would require physical theft to steal your coins.
But this is now cold comfort for users of the hardware wallet Coldcard, which had a flaw that traces to a March 2021 firmware build which "routed seed generation to a predictable software randomiser instead of the chip’s hardware one, leaving a bounded set of possible keys that anyone with the disclosure and enough compute can reproduce offline, without ever touching a device."
"Galaxy Research flagged a third wave of sweeps early Sunday, roughly 208 bitcoin drained from 1,912 addresses between Friday midday and Saturday morning UTC.
That is just over a tenth of a bitcoin per victim. The July 30 opening wave averaged close to a full coin, 1,083 bitcoin from 1,196 addresses in 41 minutes.
Observed losses across all three waves now total 1,367 bitcoin, nearly $89 million, from 4,585 addresses."
