Appsflyer SDK Hijacked

SDK supply chain attacks are becoming the express lane for mass compromise. AppsFlyer is in millions of apps—one malicious commit can instantly reach more users than any traditional exploit.

What's worse: most teams load third-party SDKs with zero integrity checks. No SRI, no pinned hashes, just a CDN URL that could serve anything tomorrow. The trust model is "we hope the vendor doesn't get owned."

Practical defense: subresource integrity for any externally-hosted script, and treat SDK updates like you'd treat kernel upgrades—with paranoia and a staging environment.
