XRP Bug Could Have Let Hackers Print Billions in Crypto Out of Thin Air
AI-summarised brief · reviewed before publication
The XRP Ledger fixed a critical integer‑overflow bug that could have allowed attackers to mint counterfeit XRP by exploiting the payment engine’s 64‑bit math without overflow checks. The flaw, present since 2015, would let a single transaction consume many offers, wrap the total amount, and pay offer owners in full while charging the buyer almost nothing. Researcher Cayden Liao reported the issue on September 22, prompting RippleX to test it and release a patch in xrpld 3.4.1 on September 25. The update also addressed a separate, less severe Batch feature bug. No evidence of exploitation on the public network has been found.
💡 Why It Matters
- · The fix protects XRP’s fixed supply, preventing a potential $88 billion‑valued currency from being inflated.
- · It underscores the importance of continuous security auditing in blockchain systems.
