In a tweet announcing the shutdown, SpankPay reassured customers, "Rest assured your money is safe and we'll get it to you as soon as possible" — always a scary thing to hear from a crypto company.
It seems that only the payments processing side of the business is shutting down, with projects including SpankChain and SpankMatch continuing to operate.
In addition to standalone servers, General Bytes' cloud service was impacted, and the company announced that it would be permanently shuttering it. "It is theoretically (and practically) impossible to secure a system granting access to multiple operators at the same time where some of them are bad actors," wrote the company in their statement explaining the decision, apparently unaware that this is something software companies find themselves doing all the time.
This exploit was the second breach suffered by General Bytes this year, after hackers exploited a vulnerability in August 2022 that allowed them to steal customer funds. It's unknown how much was stolen in that attack. The company also patched multiple hardware and software issues in their ATMs in September 2021, after Kraken Security Labs discovered issues including poor security practices that would allow attackers to "walk up to an ATM and compromise it".

According to the BBC, dozens of high-profile individuals in Romania, including members of the government and academics, lost money to the scam after it was promoted by technology expert Gabriel Garais — who also says he lost money in the scheme.
iEarn Bot claims to be a US-based company, although its website is full of false information. The person named as the company's founder told the BBC he has nothing to do with the scheme, and companies and institutions listed as "strategic partners" say there is no such partnership.
The BBC identified one cryptocurrency wallet that received payments from around 13,000 others totaling nearly $1.3 million.
On March 17, blockchain security company BlockSec observed an attacker trying to exploit a vulnerability in the NFT lending project Paraspace. Although they had successfully identified a vulnerability that could have allowed them to steal 2,900 ETH (a bit over $5 million), their attempt to execute the hack failed because they didn't correctly estimate what it would cost them in gas fees.
After observing the attempt, BlockSec executed a whitehat rescue, where they successfully executed the same attack to remove the funds from Paraspace and secure them until they could return them to the project team.
Incredibly, the exploiter sent an on-chain message to BlockSec: "hey man, I am the one who made the contract you just copied, I couldn't make it work for a stupid gas estimation error. since I lost a lot of money trying to make it work, it would be cool to get at least some of them back... best of luck". Altogether, the would-be attacker spent around 0.7 ETH (~$1,200) on gas fees while trying to pull off the hack.
According to the US DOJ, ChipMixer had been used to process, among other things, proceeds of the massive March 2022 Axie Infinity hack by a North Korean cybercrime group.
US law enforcement seized two domains and a Github account tied to the organization, and German law enforcement seized ChipMixer's back-end servers and $46 million in cryptocurrency.
Holders trying to use the exchange approved transactions which they didn't realize allowed the phishers to drain their ETH. So far, the scammers have stolen around 74 ETH ($130,500).
Around $11.9 million of tokens were sent from the Balancer defi liqiuidity project to Euler during the attack, prompting Balancer to pause the project.
The Angle Protocol decentralized stablecoin project also disclosed that almost half of the total value locked in the project — around $17.6 million in the USDC stablecoin — were sent to Euler during the hack.
Mark Zuckerberg had once talked about eventually using NFTs for Meta's metaverse projects, suggesting that eventually "the clothing that your avatar is wearing in the metaverse, you know, [could] be basically minted as an NFT and you can take it between your different places". It sounds like that plan may no longer be on the table now.
Euler announced that they were aware of the exploit, and were "working with security professionals and law enforcement".
On April 3, Euler Finance announced that they had completed successful negotiations, and that "all of the recoverable funds taken from the Euler protocol on March 13th have now been successfully returned by the exploiter". Unfortunately, based on on-chain transfers, this appeared to only be around $31 million.
