Blockchain hackers netted over $100 million in Q1 2021
Cryptocurrencies had a strong start this year, with crypto asset prices, such as Bitcoin (BTC), reaching record-heights. However, that caught the attention of cybercriminals.
Theteam found that cybercriminals stole around $108.3 million from various blockchain projects in the first quarter of 2021 — a 46% rise from the same period last year. Ethereum DApps, blockchain wallets, and cryptocurrency exchanges were the criminals’ target of choice.
The numbers are based on the data provided by, which aggregates information about disclosed attacks aimed at blockchain projects. The data also considers blockchain scams, which make up a little over one-fifth of all blockchain hack events in 2021 Q1. Monetary losses were calculated based on the conversation rate of a particular cryptocurrency at the time of a hack or scam event.
Ethereum (ETH) DApps, decentralized applications based on the Ethereum smart contract, were the most popular blockchain targets among cybercriminals in the first quarter of 2021. They were affected by a total of 11 breaches and 5 scam events, which amounted to over $86 million in losses.
Blockchain wallets, digital wallets that allow crypto owners to store and manage their cryptocurrencies, were also commonly attacked. There were 9 blockchain wallet breaches recorded in the first three months of this year, as well as 1 scam event and 2 blackmail cases. In total, they cost victims approximately $19.3 million.
Finally, cryptocurrency exchanges, platforms that facilitate the trading of cryptocurrencies for other assets, had 4 breaches and 1 scam event. Together cybercriminals collected around $2.9 million from cryptocurrency exchanges in 2021 Q1.
Blockchain-linked hacks are on the rise again
In our report on, we observed a decline in breaches for the first time in the last five years. However, a new year brings new challenges. After analyzing blockchain-linked breach and scam data of 2021, we see an upward trend once again.
The first quarter of 2021 already saw 33 breaches, including scams, affecting Ethrereum DApps, blockchain wallets, and cryptocurrency exchanges. It signifies a 154% rise compared to Q1 of 2020, when 13 blockchain-related breaches were detected.
However, the number of blockchain-linked breaches in Q1 of 2021 is still almost two times lower than in the record year of 2019. In the first quarter of 2019 alone, 62 blockchain breaches were detected.
If we contrast this year’s numbers to those of the first quarter of last year, breaches and scams affecting ETH DApps jumped by 433%, from 3 in Q1 2020 to 16 in Q2 2021. In the meantime, hacks affecting blockchain wallets rose by 140%, from 5 in Q1 2020 to 12 in Q2 2021.
Finally, successful attacks aimed at crypto exchanges increased by 67%, from 3 in Q1 2020 to 5 in Q1 2021. However, unlike last year, there were no breaches involving blockchains or TronDapps recorded in the first three months of 2021.
The busiest month for cybercriminals was March, when they launched 14 successful attacks, while the least active one was January with 8 attacks. The remaining 11 breaches took place in February.
Due to their nature, blockchain projects remain profitable targets to cybercriminals because fraudulent transactions cannot be reversed as they often can be in the traditional financial system. With cryptocurrencies entering into their golden age as totalat the beginning of this year, it is safe to say that we can expect more hacks to pour in by the end of this year.
