Every recorded CoolWallet security incident, newest first, with severity, fix status and sources.
CoolWallet S owners whose phone was stolen or infected could have their seed, PIN and pairing password exposed by the Android app. CoolWallet states the risk was limited and that the logging, screen-capture and bypass issues were fixed in its next app release.
More entries do not mean a less secure brand: widely sold devices draw more published research and more targeted attacks, and some vendors disclose more than others.
