Quantstamp 2023 Web3 Security Year In Review

$75.32M was lost across 32 crypto incidents in June, up from May's $59.52M. No coordinated campaign carried the month, but one targeted operation did. A targeted social-engineering attack against Humanity Protocol reached the keys behind the $H token and drained $32M, roughly 42% of every dollar lost in June. Quantstamp led the independent investigation and traced the tooling to a phishing campaign previously seen targeting macOS users. Offchain, a fresh npm supply chain wave hit Red Hat's packages on the first day of the month, and a PeopleSoft zero-day was exploited for two weeks before Oracle said a word.

$59.52M was lost across 29 crypto incidents, down sharply from April's ~$635M. No single hack carried the month. The bigger story happened off-chain, where a self-propagating npm worm called Mini Shai-Hulud kept resurfacing in new waves through the month, ultimately spanning more than 1,000 malicious package versions across the npm ecosystem.

April was undoubtedly a rocky month in security. $635M was lost across 28 crypto incidents. The Axios npm package was compromised on day one, exposing an estimated 600,000 installs in three hours. Vercel was breached through a third party. Three major CVEs under active exploitation. Here's the month in security 👇
