In May 2015, the server was compromised through a social engineering attack on the sites ISP (internet service provider).

The service launched in 2014, and by March of 2015 there was no response to requests for withdrawals. Roughly $1m USD was pocketed by the CEO. While he has been arrested, it does not appear that funds were recovered as they'd already been spent. T...")

In general, hot wallets cannot be considered safe storage. This exchange or platform is based in Panama, or the incident targeted people primarily in Panama. == About Coinapult == “Coinapult COO and CFO Justin Blincoe stressed that the hot wallet was used only for funds owned by the bitcoin wallet and service...")
• 14:44, 24 January 2023 Azoundria talk contribs created page Allcrypt (Created page with "{{Imported Case Study|source=https://www.quadrigainitiative.com/casestudy/allcrypt.php}} It’s always fascinating to hear about an essentially anonymous exchange operator who secured the exchange only with Wordpress, taunted hackers on Twitter, and then was rude to customers after the fact. Luckily, this exchange didn’t achieve any significant volume, which is not surprising. Had they invested in a simple multi-sig cold storage wallet, all could have been avoided. T...")
• 14:44, 24 January 2023 Azoundria talk contribs created page BTER Bitcoin Heist (Created page with "{{Imported Case Study|source=https://www.quadrigainitiative.com/casestudy/bterbitcoinheist.php}} thumb|BTERBTER stored their funds in a single wallet, which, while called a "cold wallet", was not entirely offline and disconnected, being as it was on a managed server. The wallet was breached. The platform ultimately gave affected users balances that were owed to them, which were repaid over time from profits, and discounts on trading. A partnership gav...")

The operation also highly lacked transparency, promised a high rate of return, and it is unclear whether funds were ever backed to begin with. This exchange or platform is based in China, or the incident targeted people primarily in China. == About KipCoin == “Another Chinese based excha...")

While we can look back and see this as a Ponzi scheme, the key issues at the time include a lack of knowing who’s behind the operation, lack of any sort of registration, and no visibility into the financial status of the exchange. An environment wh...")

The customer legitimately requested the withdrawal and failed to notice the changed address. “796” appears to have handled this well, and the situation was quickly made right. No other customers appear to have been affected. It is sugges...") Tag: Visual edit: Switched

Wallets were generated in a predictable way with a less secure R value for a few hours. This meant that the funds in those wallets could be snatched up by hackers. A combination of black and white hackers took funds. It would appear that blockchai...")

A hacker managed to break into the platform and steal the funds. The first thing which BTER attempted was to negotiate a chain split. However, the majority of NXT nodes opposed the split and it did not pr...")

The exploit suggests that all the coins taken were stored in a hot wallet, so smaller reserves or any sort of time delay would have reduced the losses. Any platform protecting the funds in cold storage would have...")

They’re also apparently based in the United States and working with regulators, yet unable to serve a...")
