GoxThe most famous incident that everyone has heard of. Lack of secure storage for funds, a CEO who had his focus elsewhere, and the hacks apparently went undetected for months. There is still an ongoing bankruptcy. Luckily, at least one of the cold wallets escaped capture and can be used for disbursement. While victims have massive l...")
• 12:22, 22 January 2023 Azoundria talk contribs created page Intersango Exit Scam (Created page with "{{Imported Case Study|source=https://www.quadrigainitiative.com/casestudy/intersangoexitscam.php}} Although this was not reported officially, I kept coming across stories of the bitcoin exchange Intersango and people who reported never being able to withdraw their funds. Even posts going into 2016 and 2017 seemed to report that the matter was never resolved. It seems very likely that the exchange just didn’t have enough users with significant balances to warrant a law...")

On November 21st, 2013, it appears that a vendor exploited a security hole in the website to make off with 5400 bitcoins, which is believed to be the sum of all funds on the site. The bitcoin was ultimately traced to two i...")

The service suffered attacks on October 23rd, October 24th, and a final time on November 8th.

• 14:04, 21 January 2023 Azoundria talk contribs created page BIPS Wallet Service (Created page with "{{Imported Case Study|source=https://www.quadrigainitiative.com/casestudy/bipswalletservice.php}} In the earlier days of bitcoin adoption, these kinds of custodial wallet services were actually in use, and users were storing their funds in what was essentially a hot wallet managed by a third party. Although some reporting here suggests that only a portion of the funds were stolen, there does not appear to be any indication that any of the affected users got anything bac...")

Instead, all of the funds were likely stored in a hot wallet, and this hot wallet was breached. From what I have read, the owner appears to have been doing his best to run a legitimate business operation, and simply lacked the education and technical know-how to properly secure the fun...")

This also shows the very real tendency of some exchange operators to hide key details of hacks that occur, which is why a mandated level of transparency is so critical.
