Recently I was reading about how custodial exchanges are hacked, there has been several exchanges that has been hacked since 2011 till now, and the last one that happened was just this Thursday that have just passed away which was yesterday, the exchange involved was hotbit, it was not an actual hack that led to loss of coins, but the hotbit database was compromised by hackers.
What makes me surprise after the whole reading, I noticed custodial exchange are making use of hot wallet for customers satisfaction, that alone will encourage hackers that they can do it, that they can be able to hack exchanges because they are using hot wallet wallet to handle customers cryptocurrencies.
https://hotbit.zendesk.com/hc/en-us/articles/1500008915521-Hotbit-s-Announcement-on-Emergency-MaintenanceIf you have an account on Hotbit, the following are things you should be aware of1. The attacker has already gained access to the database, so your registration phone number, email address and asset data might have leaking risk. However, the password and 2FA key are encrypted so theoriotically should be safe. But from the security point of view, if your account and password on another website or app are the same as Hotbit's, it is safer to change the password now;
2. If you receive an email or private message in the name of Hotbit, you can contact us through official channels (Twitter, Facebook, Telegram) to verify identity before replying;
3. Leveraged ETF products are not suitable for long-term holding and therefore Hotbit will be fully responsible for all losses suffered by the position-holder during the maintenance period.
4. Your Open Orders on Hotbit will be canceled when the system is restored to avoid unintended trading losses.
5. All daily routine income distributions (such as investment products, current products and FIL cloud computing power ) will be paid out after the maintenance is completed .
Never hodl on exchanges, move your funds to noncustodial wallet, offline wallet is the best for security.
