Microsoft Azure CTO set Claude on his 1986 Apple II code, says it found vulns
What happened
AI can reverse engineer machine code and find vulnerabilities in ancient legacy architectures, says Microsoft Azure CTO Mark Russinovich, who used his own Apple II code from 40 years ago as an example. Russinovich wrote: "We are entering an era of automated, AI-accelerated vulnerability discovery that will be leveraged by both defenders and attackers. This matters for IT, Telecom & Cyber because fresh price movement and input-cost detail should reset bid assumptions, breach response slas, and negotiation guardrails with 40, 1986, 6502 as the clearest commercial anchors; expect renewal uplift asks
Buyer takeaway
For IT, Telecom & Cyber, treat this as a cost-boundary signal rather than just a headline; buyer assumptions may need refreshing before the next quote or award decision
Cost / money
Use this to refresh should-cost views and challenge any fast repricing. Keep the read-through directional unless the source itself provides hard commercial numbers
Supplier / commercial
Suppliers with fresh cost justification may push harder on reopeners, indexation, shorter quote validity, or pass-through language. Buyers should separate real drivers from negotiation posture
Safety / operations
The operational risk is indirect: tight budgets or repricing battles often reappear later as reduced slack, substitutions, or execution compromises that buyers then have to manage
What to watch
Watch for shorter quote validity, reopeners, pass-through requests, or attempts to reset pricing on the back of weak evidence
