Top 8 Crypto Hacks in 2023

2023 has been a year of significant growth and adoption for the cryptocurrency industry, but it has also been a year of major hacks and exploits. In the first 10 months of the year, nearly $2 billion worth of cryptocurrency has been stolen from crypto exchanges, DeFi protocols, and other crypto projects. In 2022 crypto hacks represented a record of $3.8 billion and sadly 2023 is taking the same path. We can argue that 2023 will, in fact, be worse as the overall crypto market is lower in 2023 compared to 2022, the number of assets stolen in 2023 is actually higher even though the USD value is lower.

The top 10 crypto hacks of 2023 so far have resulted in the theft of over $1 billion worth of cryptocurrency. The most common exploit used by hackers is the flash loan attack, which allows hackers to take out large loans and then use them to manipulate the price of assets in order to make a profit. Other common exploits include cross-chain bridge exploits, hot wallet compromises, and supply chain attacks.

In this article, we will take a closer look at the top 8 crypto hacks of 2023 so far, with a focus on the exploit used by the hacker. But first, before jumping into our top 8, we would like to remind you that the safest way to protect your assets is to use a hardware wallet such as a D’CENT Biometric Wallet. It allows you to embark for self-custody meaning no-one but you have access to your private keys and recovery phrase, in other words, no-one but you can transfer your tokens.

Closing

The crypto industry has been plagued by hacks and exploits in recent years. The more the industry will grow the more hackers will be interested to try crypto services’ security. In order to keep your asset safe, there are some basic rules. First, always remember that not your keys, not your coins, therefore:

✅Use self-custody solution, best is to use a hardware wallet as D’CENT Biometric Wallet

✅Never share your private keys, no customer support would ever ask this no matter the problem, having your private keys would not help to fix anything, it is a scam

✅Take care when connecting your wallet to web3 providers and to smartcontracts. Via our D’CENT App you can double check the permissions allowed the contracts interacting with your wallet and change the permissions if required
