Three security breaches involving more than $40 million in stolen cryptocurrency occurred last week, according to on-chain analyst Specter, who shared the assessment on X. The losses included $25.6 million taken from a whale address on OpenSea beginning with 0x8fEB0, known as TLBL. Specter said substantial capital also flowed into the market during the period, while hackers primarily used social engineering and phishing links. The incidents underscore that security is part of cryptocurrency investing, requiring users to follow evolving hacking techniques, vulnerabilities and phishing methods rather than simply buying assets and ignoring them.
