Coinbase, Betterment, Transferwise and Prosper are a few of the names from the 10,000+ firms effected by the bug at the large ISP. The incident highlights the broad issues that can be caused by a single point of failure in the widely connected world of cloud computing.
The bug that hit Cloudflare was discovered by a researcher at Alphabet Inc.’s Google a week ago. Cloudflare said it is working with Google and other search-engine companies to remove any leaked data, most of which it said had been scrubbed by Thursday evening. It wasn’t immediately clear which companies, or how many, might have been affected. Cloudflare, which says it has over 5 million customers, publishes only a partial list. Its clients include dating site OkCupid, and AgileBits Inc., maker of the 1Password security software, according to Cloudflare’s website.
