Recent advances push Big Tech closer to the Q-Day danger zone

Recent advances are pushing Big Tech closer to the "Q-Day danger zone," according to Dan Goodin on April 17, 2026. Both Google and Cloudflare recently accelerated their internal deadline for PQC readiness to 2029, a roughly five-year acceleration. This move was prompted by research indicating that CRQC may arrive sooner than previously estimated. This scenario is reminiscent of the 2012 discovery of sophisticated malware known as Flame, which exploited MD5, a cryptographic hash function Microsoft used to authenticate digital certificates, despite MD5's known vulnerabilities since 2004. Organizations are now replacing RSA and elliptic curves, which are vulnerable to Shor's algorithm, to prevent similar widespread issues.
