What happened
The Hacker News reports that attackers stole roughly $2.7 million from Polymarket traders by hijacking a DebugBear script — DebugBear being a third-party web performance/monitoring service whose JavaScript runs inside customers' pages. The published excerpt is truncated at the headline and opening lines, so the article body (how the script was hijacked, when, and which pages served it) is not available here. What is concrete: a third-party vendor script was the delivery path, and the loss is measured in millions of dollars.
Why it matters
Any third-party tag you paste into your frontend — performance monitoring, analytics, chat widgets, A/B testing — executes with full access to your page's DOM and your users' authenticated sessions. If you ship a product where a session can move money or assets, a compromised vendor script is not an SEO/performance problem, it is a wallet-drain problem. The concrete action: list every external script on your money-touching pages this week, and for each one decide whether it can be self-hosted, pinned with Subresource Integrity, or removed entirely — 'we trust the vendor' is exactly the assumption that cost $2.7M here.
Discussion angle
Walk through your own stack live: which third-party scripts load on your login and payment pages, and would Subresource Integrity even be possible for each one? For anyone who can't answer, that's the takeaway.
