$80 million taken from EasyFi lending platform
Hackers compromised a computer belonging to EasyFi founder Ankitt Gaur, accessing his private keys which allowed them to transfer $6 million in stablecoins and $120 million worth of EASY. The price of EASY crashed as a result of the low liquidity, limiting the hacker's total payout to around $80 million. EasyFi followed the breach with a hard fork to "EZ 2.0", and compensated users with a mix of stablecoins and "IOU tokens" that could later be redeemed for discounted EZ.
Africrypt investors disappear with $3.6 billion of investor funds

FTX loses $800 million to MobileCoin market manipulation
At some point in April 2021, a trader on the FTX cryptocurrency exchange successfully exploited the firm for around $800 million. They were able to take positions in relatively illiquid crypto tokens, including MobileCoin and BTMX, then manipulate the token prices to appear much higher than their true market value (for example, MobileCoin spiked to $70 a token, rather than around $6). Using these falsely high-valued tokens as collateral, the trader was able to borrow around $800 million in more liquid tokens, abandoning the relatively valueless collateral on the exchange.
During the October 2023 criminal trial of FTX founder and CEO Sam Bankman-Fried, he gave more detail on how the exploit took place, and admitted that he personally had disabled FTX's automatic liquidation systems for this account. Though he intended to closely monitor the account to prevent any losses to FTX, he said that it was actually his actions that allowed the trader to drain such a massive quantity of assets from the exchange.
Prosecutors alleged that Bankman-Fried later had his cryptocurrency trading firm, Alameda Research, shoulder the loss, saying that he'd hoped it would be less visible on Alameda's balance sheets than on FTX's.

Creators of "Turtledex", a project offering decentralized storage, make off with $2.5 million
24 hours after pre-sale, the team behind Turtledex drained $2.5 million from the liquidity pool and disappeared. Turtledex's smart contract had been audited shortly before the sale, with no major issues found, leading some to question the point of such audits.
Social token platform Roll hacked for $5.7 million
Private keys for hot wallets on the Roll network were compromised, allowing the theft of around $5.7 million from various "social tokens". "Friends With Benefits", an a16z-backed DAO with an associated token that allows those who are approved by the DAO and can afford the ~$8,000 entrance fee access to exclusive parties, was one of the tokens affected, and it tanked in value by about 96%. Roll apologized and announced a fund to help those affected, though the $500,000 fund was only a small fraction of the money lost.
A headline-making $69 million NFT sale looks an awful lot like a publicity stunt
Vignesh Sundaresan's $69 million purchase of an NFT by artist Beeple made headlines. However, Amy Castor outlined a few days later that Sundaresan is a business partner of Beeple's, and that Beeple himself owns 2% of the B20 tokens created by Sundaresan's cryptocurrency investment firm. She speculates that money may not have exchanged hands at all, but that Sundaresan and Beeple orchestrated the purchase to artificially inflate the value of the work, increase Beeple's popularity, and draw attention to Sundaresan and his company.

Indie Developer sells commissioned pixel art as NFTs without permission from original artists
Jason Rohrer, developer of the 2014 indie game The Castle Doctrine announced his plan to auction 155 of the digital paintings that he had commissioned for the game as NFTs on the OpenSea platform, without ever requesting permission from the original artists or informing them of his plan at all. In an email, Rohrer told Kotaku that he hadn't asked for permission from the artists to sell the works as NFTs "mostly because having email conversations with 50+ people would exceed my bandwidth as a solo creator." At least three artists asked for their work to be removed from the collection.
An NFT artist changes all images in their collection to photos of rugs to make a point about the value of NFTs
NFT artist "neitherconfirm" created a collection of 26 NFTs of stained glass-style computer-generated art. After release, they changed the art for each NFT to a picture of a rug, an apparent reference to "rug pulls". The artist wrote on Twitter, "Nobody got hurt. It is pretty easy to change the jpg, even if it does not belong to me or it is on auction. I am the artist, my decision, right? A thread from somebody making his living with art irl about the value of NFTs... All discussions about the value of NFTs are meaningless as long as the token is not inseparable from the artwork itself... What is the meaning of creating an unforgeable token on a highly secured network if somebody can alter, relink or destroy your possession? As long as the value of your artwork is reliable on a central service you do not own anything."
Hackers take $3.8 million from DODO

An attacker steals $3 million from the PAID Network
A contract exploit allowed a hacker to mint almost 60 million PAID tokens (priced at around $160 million based on the value before the attack) on the PAID Network. The hacker then made off with about $3 million in Ethereum from their efforts. The attack caused the PAID token to crash about 88% in value over the course of a day, from around $2.86 to $0.32.
