Inventory | More than 41 typical security incidents occurred in August. How many more hacking schemes do hackers have?

It’s time for another monthly security inventory again! Beosin-Eagle Eye opinion monitoring shows that in August 2021, various security incidents are still frequent. According to Beosin’s statistics, more than 41 typical security incidents occurred in August.

This month’s security incidents continue to focus on exchanges, DeFi, crypto scams and other fields, which often cause huge losses. Here, Beosin advises users learn more before participating in some projects to avoid being cheated. Another thing to notice is that the project party should pay attention to security precautions, and it is best to find a professional security audit company in the industry to conduct audits before the project goes online, so that hidden risks can be found and solved immediately.

Beosin’s Review

The largest DeFi hacking incident of the year happened this month! For this incident, the project party was also helpless in front of the hacker. Thankfully, the white hat hacker eventually returned the stolen assets. In addition, for ordinary people, it is also important to take good care of their own digital assets.

Beosin’s Review

The sickle for harvesting leeks has been raised! Where there is interest, there will be crimes. If you dream of overnight riches, then you will often fall into the trap of fraudsters. If you find yourself cheated, you should promptly retain the relevant evidence, transfer the funds out, reduce losses, and then report to the local public security authorities as soon as possible. Beosin here reminds everyone to pay attention to the virtual currency fraud.
