Sep 23, 2014 Monero
On July 24, 2014, bitcointalk.com member BitcoinEXpress (“BCX”) replied to a thread on the bitcoin-focused forum indicating that in under two hours he had discovered and gained possession of an exploit in the codebase of Monero (XMR).

FYI, altcoins are decentralized digital currencies like bitcoin that are secured by cryptography.
