Around $700,000 of the stolen assets were frozen thanks to intervention by a security firm called ZeroShadow, although this represents only 0.2% of the total loss.
Crypto holder loses $283 million to scammer impersonating wallet support
A crypto holder has lost $282 million in bitcoin and litecoin after a scammer impersonating a customer support employee for the Trezor hardware wallet manufacturer successfully convinced them into revealing their seed phrase. After gaining access to the assets, they quickly swapped them to the Monero privacycoin. The volume of assets was so large that the Monero price spiked as the scammer laundered the finds. The scammer also swapped assets using the THORChain project, which boasted on social media about the "World record speedrun. ⚡️" (presumably without realizing they were bragging about a thief using their project to launder money).
Garden hacked for $11 million
The Garden bitcoin bridge suffered a roughly $11 million loss after one of its solvers was compromised. These solvers essentially act as market makers for the protocol. Some blockchain sleuths have questioned whether the affected solver, which Garden described as a separate entity, may actually be operated by the same team as Garden.
There wasn't much sympathy to be had for Garden after this exploit. The protocol had recently announced hitting a milestone of bridging more than $2 billion in assets, but the celebration was criticized after zachxbt pointed out that a substantial portion of the bridged funds were proceeds of crimes being laundered to evade detection and recovery.
Yala stablecoin depegs after $7.6 million theft
The YU bitcoin-backed stablecoin lost its intended dollar peg after what they described as "an attempted attack", later writing that there was an "unauthorized transfer of funds". Although they initially wrote that "All funds are safe", they later stated that they "identified the stolen assets on-chain and are actively working with law enforcement to pursue recovery." Research firm Lookonchain observed a large mint of the YU token that may have been related — if so, the attacker successfully stole at least 1,501 ETH ($6.75 million), and holds a substantial quantity of YU they still haven't sold.
Despite the project's attempted reassurances, the YU stablecoin lost its $1 peg, plummeting as low as around $0.20. As of writing, about a day later, the stablecoin is still well below its peg, at around $0.94.
Bitcoiner socially engineered out of $91 million
A bitcoin holder reportedly fell for a social engineering attack after receiving communications from scammers posing as customer support for a crypto exchange and hardware wallet provider, according to crypto sleuth zachxbt. The thieves stole 783 BTC (~$91 million), which they then transferred through the Wasabi mixer to complicate tracing.
Odin.fun bitcoin memecoin launchpad exploited for more than $7 million
Odin.fun, a bitcoin-based memecoin launchpad sort of like the popular pump.fun, was exploited for 58.2 BTC (~$7 million). The attacker had apparently manipulated the price of various tokens, then withdrew bitcoin based on the inflated prices.
A team member suggested they were unsure of the total amount stolen, "but as of right now, our company treasury isn't big enough to cover the losses".
$330 million in Bitcoin apparently stolen; laundering spikes Monero price by over 40%
3,250 BTC (~$330 million) were apparently stolen from a bitcoin holder and then quickly moved through multiple exchanges and swapped for the Monero privacycoin. Such a massive swap into Monero was apparently enough to cause the Monero price to spike from around $230 to as high as around $330, before retracting somewhat.
Coinbase customer loses $35 million in bitcoin theft
A Coinbase customer reportedly lost 400 BTC (~$35 million) in a scam identified by blockchain sleuth zachxbt. While investigating the massive theft from the single customer, he also observed at least $11 million in thefts from various other Coinbase customers throughout March.
zachxbt has previously accused Coinbase of not doing enough to protect customers from hundreds of millions of dollars in scams, and he noted that in these cases, Coinbase had not marked the thief wallets as malicious in various cryptocurrency compliance tools.

Crypto holder loses $40 million to sophisticated phishing attack
A plaintiff named Mandar Mirashi has filed a lawsuit against an unknown defendant accused of stealing around $40 million in bitcoin through a sophisticated phishing attack and/or device compromise. After receiving suspicious emails from or appearing to be from Google, the Ledger hardware wallet manufacturer, and Apple, and after observing an apparent device compromise allowing an attacker to delete his Reddit account without his involvement, Mirashi moved 300 BTC from a Ledger hardware wallet, believing it to be compromised. An attacker then attempted to steal the funds from the hot wallet where he'd moved them, but Mirashi was able to intervene in time to cancel the transaction. Mirashi moved the funds back to the Ledger, only to discover the next day that around 522 BTC had been stolen from two of his Ledger wallets.

Crypto holder loses assets priced at $2.5 million
A crypto holder tweeted at the Ledger hardware wallet manufacturer to report that 10 BTC (~$1 million) and "~1.5m of NFTs" had been stolen from a Ledger wallet they were using. "The ledger was purchased directly from you. The seed phrase was stored in a secure location, never entered anywhere online. I never signed any malicious transactions. Everything is in my physical possession.I haven’t touched this ledger in 2 months," they wrote.
Some blamed the theft on an apparent malicious Ethereum transaction the user had signed nearly three years prior. However, while a malicious transaction signature on Ethereum could explain the NFT thefts, it should not alone enable the theft of assets on the separate bitcoin blockchain.
Despite this, Ledger blamed its customer, telling a media outlet that "As we know, the user got phished when it comes to the ETH wallet, we can assume user error on the BTC side too".
M2 cryptocurrency exchange hacked for $13.7 million
The UAE-based M2 cryptocurrency exchange was hacked for $13.7 million in bitcoin, ether, and Solana tokens. The exploiter compromised several of the exchange's hot wallets to take the funds.
Shortly after the theft, M2 acknowledged the hack and announced that "the situation has been fully resolved". This apparently involved M2 restoring customer funds from their own assets, rather than recovering the stolen assets.
