COFFER - Cyber Security Expert Joins Pleb Underground

- Ledger hardware wallet compromised via third-party reseller; attackers drained approximately $86–100 million in user funds despite Ledger's security measures. - Best practices for purchasing signing devices include buying directly from manufacturers, paying in cash or Bitcoin when possible, and avoiding third-party resellers. - Firmware updates and refreshing devices with manufacturer-signed versions mitigate supply chain attack risk; maintaining updated software across all devices protects against most active threats. - Cold Card's five-year vulnerability exploited in a sophisticated, precise attack raises questions about whether it was an inside job versus external hacking; closed-source code components prevent community security review. - Social engineering and phishing remain the primary attack vectors (80–85% of data breaches); attackers pose as legitimate companies, government contractors, and support teams to bypass user defenses. - OPSEC (operational security) requires understanding personal risk tolerance, trade-offs, and threat models; everyone remains vulnerable despite expertise, but knowledge reduces susceptibility.
