In 2020, the world has changed. After the initial shock of the pandemic and the subsequent collapse of markets, people adjusted to the new isolating reality. One of the fundamental changes in everyday life was the mass transition to remote work.
Against this background, the number of cyber crimes has significantly increased. As the researchers predict, the number of attacks will continue to grow.
The cryptocurrency community and companies have long been targeted by hackers. According to analysts, Until October 2020, the blockchain industry has lost over $13.6 billion in attacks since 2012.
Unfortunately, the hacking of Bitcoin exchanges and wallets is far from new and in year 2020, amid the boom, DeFi projects have become a favorite target of hackers. Cipher Trace estimates that by November 2020, attackers had stolen almost $100 million from DeFi protocols.
We will tell you about the main hacks of 2020, because of which users lost millions of dollars, and some companies closed down altogether.
- The biggest hack of the year was the attack on the cryptocurrency exchange KuCoin.
- Most often in 2020, DeFi protocols suffered from intruders actions. They attacked several users using instant loans.
- Besides hacking protocols and platforms, cybercriminals actively traded user data.
KuCoin — one of the largest hacks in history (damage — $280 million)
The September 2020 attack on the cryptocurrency exchange KuCoin was one of the largest hacks in the crypto’s history industry.
Initially, the damage was estimated at $150 million, but later analysts changed the estimate to $280 million. Hackers who hacked KuCoin laundered funds through mixers and the decentralized exchange Uniswap. By November, KuCoin returned most of the stolen funds to users and restored the deposit and withdrawal of coins.
Dforce Hack (damage — $25 million)
In April 2020, a hacker attacked the dForce DeFi protocol. At the time of the theft, the amount was almost $25 million. He took advantage of the vulnerability of the imbtc token which was an ERC-777 standard and a critical vulnerability in the smart contracts of the platform, Lendf.me responsible for updating user balances. Besides the damage caused to dForce, the hacker took out all the tokens from Lendf.me (291 imbtc or $2 million at the time of the attack).

As a result, Singapore law enforcement officers caught hacker, and he had to return all the stolen funds.

Attackers actively traded user data

Will cybercriminals attacks on the cryptocurrency industry in 2021 continue? Experts believe that yes. However, leading cryptocurrency projects do not wait for hacker attacks — they devote more and more time to their security systems, and experts issue reports and recommendations on methods of protection and counteractions.
In, future companies that put the user funds security and user data as their top priority will take large crypto market share.
