Vercel Breach Shows How Infostealer Malware Creates Supply Chain Risk

Vercel's security breach originated from an infostealer malware infection in February, demonstrating how endpoint compromises can escalate into major supply chain incidents. Infostealer malware specifically targets stored credentials, browser passwords, and authentication tokens, which attackers then use to gain unauthorized access to corporate systems. This incident highlights the critical importance of endpoint security at service providers, as a single compromised employee device can potentially impact thousands of downstream customers who rely on the platform.
