Ripple Ex-CTO Sounds Alarm Over ‘One of the Worst Security Flaws’ He’s Ever Seen

Ripple’s former chief technology officer, David Schwartz, issued a sharp public warning this week over a newly surfaced Windows BitLocker vulnerability, describing it as one of the most serious security flaws he has encountered in years.

His remarks landed alongside a separate alert about a wave of scams targeting XRP Ledger users, signaling rising pressure on both consumer device security and on-chain trust.

Schwartz Issues Stark Security Warning Over BitLocker Flaw

Schwartz said the exploit allows attackers to bypass Microsoft’s full-disk encryption using a basic USB-based method. The lack of authentication prompts has fueled speculation that the mechanism resembles a backdoor more than a conventional bug, given how little technical effort the reported access path requires.

The flaw matters for anyone storing sensitive material on a Windows device, including private keys, recovery phrases, or work documents. Schwartz’s prior commentary on protocol-level security and incentive design has drawn wide industry attention, lending weight to his assessment of the BitLocker issue.

The disclosure adds to broader concern about software-level attacks moving into crypto-adjacent territory, where private key exposure can trigger direct, irreversible loss for retail holders relying on disk encryption to protect cold storage backups.

Ripple CTO Extends Alert Over XRPL Scam Surge

In a separate post, Schwartz flagged a sharp rise in scam reports targeting XRPL users. Fake airdrops and impersonation accounts are the most common patterns. Impersonators often clone verified profiles and prompt holders to connect wallets to drainer contracts.

The trend mirrors a broader rise in scams flagged by financial regulators in recent months. For XRP holders, the risk is amplified by the ledger’s pseudonymous nature and the absence of recourse once funds move.

Schwartz, whose public profile within the XRP ecosystem makes his advisories widely circulated, urged users to ignore unsolicited airdrop prompts and verify official communications independently before connecting any wallet.

AI-Built Exploits Add to Security Warning

The warnings arrive as Google said it had intercepted a live AI-built zero-day exploit before mass deployment. The Python-based attack reportedly bypassed two-factor authentication on a widely used open-source admin tool.

Defensive AI systems such as Big Sleep and CodeMender are now being rolled out in response. Whether endpoint encryption and consumer authentication can keep pace with that shift is the open question.
