Cybercriminals are now taking advantage of the current cryptocurrency craze to deceive potential victims and steal their digital money. In fact, a report from Chainalysis found that hackers exploited vulnerabilities within crypto platforms or used traditional scam methods such as ‘carpet pulling’, obtaining over $ 7.7 billion ( Rs 58,698 crore approximately) of cryptocurrency to victims in 2021. Here we list all the major cryptocurrency scams that have occurred this year.

Poly Network

In August 2021, hackers pulled off one of the biggest cryptocurrency heists ever by stealing $ 613 million in digital coins from the Poly Network token exchange. However, the hackers returned $ 260 million in tokens in less than 24 hours.

For the uninitiated, Poly Network is a decentralized finance (DeFi) platform that facilitates peer-to-peer transactions allowing users to transfer or trade cryptocurrencies on multiple blockchains. For example, a client could use Poly Network to transfer tokens such as Bitcoin from the Ethereum blockchain to the Binance Smart Chain, perhaps seeking access to a specific application.

Attackers stole funds from more than 12 different cryptocurrencies, including Ether and a type of Bitcoin, according to Chainalysis.

Interestingly, at first the hacker refused to hand over the stolen crypto assets. That was until Poly Network asked them to publish it, spat $ 500,000 as a gesture to find the system’s vulnerability and even offered them a job. Poly Network later revealed that the so-called “Mr. White Hat” gave them the private key.


On May 19, the PancakeBunny hack took place, cybercriminals raised around $ 45 million in a flash loan exploit and dropped the price of Bunny tokens by 96% from $ 220 to around $ 10 in 24 hours .

A flash loan is an unsecured loan where no collateral is required from the borrower, it is unsecured. We have to understand that it is automated so that the lenders automatically get their loan amount within a specific time frame. However, fraudsters take advantage of these loans by raising the price of coins and then withdrawing all of their investments causing the crypto market to fall.

The hacker borrowed more than $ 700 million in Binance Coin (BNB) from seven PancakeBunny loan pools. They used it to manipulate the price of BNB which caused the price of Bunny coins to crack. After paying off the flash loans, the hacker ended up with 114,631 BNB worth around $ 45 million.

On July 16, the company’s new Polygon blockchain fork, PolyBunny, was also hit, with a flash loan attack on Polybunny’s $ 2.1 million, dropping its tokens from $ 10 to less than 2. $.

Vulcan Forged

The gaming non-fungible token (NFT) platform for winning Vulcan Forged said it has repaid more than $ 140 million (roughly Rs 1,062 crore) in cryptocurrency to all investors, a day after its platform -form was compromise.

Squid Game Token

Millions of dollars vanished within minutes after investors crammed into a new cryptocurrency inspired by Netflix’s popular survival series “Squid Game,” to see its value drop to nearly zero in a few short hours.

Popular crypto exchange Binance has launched an investigation into the Squid token and froze the wallet addresses of token developers, calling it a potential “carpet-draw” case.
