In June, a similarly low-participation vote handed "stewardship" of the project to a different group which promised to "revitalize" Abracadabra. Days later, treasury wallets sold around $500,000 worth of MIM. In July, the project tweeted that a roadmap to restore the peg was "coming this week," then never posted again. A week after that tweet, Abracadabra-controlled wallets moved about $8.3 million in treasury assets with no explanation, some of it to a Binance deposit address, in what one commentator called "treasury looting". The wind-down proposal doesn't mention the $8.3 million or count it toward what MIM holders could redeem.
Abracadabra proposes winding down after string of hacks years ago left each $1 "stablecoin" token backed by $0.04 in reserves
Abracadabra, the defi project behind the Magic Internet Money (MIM) stablecoin, is shutting down. It blamed its string of hacks: $6.5 million theft in January 2024, $13 million in March 2025, and $1.8 million in October 2025, which altogether left about $21 million in bad debt. According to the shutdown proposal, 22 million MIM are in circulation, backed by just $900,000 in "actionable backing" which puts the supposedly dollar-pegged token at about $0.04. Two wallets voted on the proposal.
More Markets exploited for $9.3 million
Defi lending project More Markets lost $9.3 million after an attacker was able to trick the lending protocol logic and empty the project's reserve. The attack was noticed by blockchain security researchers at Blockaid; More Labs later announced they were investigating. Oddly, while acknowledging that funds had been stolen, they wrote, "Our initial investigation reveals that MORE was not exploited. MORE's contracts are secure. MORE is solvent. The protocol is paused." They claimed that only 5% of the assets were bridged out of the Flow blockchain, though did not explain how they planned to prevent the attacker from moving more tokens or collapsing the token price entirely.
Moonwell loses $8.7 million to fourth exploit in less than a year
An attacker stole around $8.7 million from the Moonwell defi lending protocol after manipulating the price of an illiquid token called MAMO. After pumping the MAMO token price, they "borrowed" various assets and abandoned the overinflated collateral.
This theft is the fourth Moonwell exploit in less than a year, following a $3.7 million oracle manipulation attack in November 2025, another oracle attack in February 2026 amounting to $1.78 million, and a $1 million governance attack in March.
KiiChain, TAC, and other Cosmos-based blockchains exploited after "negligent" vulnerability disclosure
Multiple blockchains based on the Cosmos chain suffered exploits after Cosmos Labs publicly disclosed a vulnerability in the Cosmos EVM. Some have criticized Cosmos for "negligence" in their vulnerability management. KiiChain, one of the affected chains, wrote in their postmortem, "This loss was avoidable. ... Publishing a security fix in the open, before the chains running that code have been told privately and given time to patch, hands the vulnerability to anyone reading the commit. Standard responsible disclosure exists precisely to prevent this. Cosmos Labs gave no advance notice to downstream chains, did not flag the release as security critical, and did not tell affected chains that a public release had happened until Friday 21 August, two days later."
KiiChain was exploited for around 148 million KII, which the attacker was able to cash out for around $1.6 million. TAC, a Telegram-focused blockchain, was exploited for about 3 billion TAC (~$7.5 million). Nesa Chain was exploited, and though an attacker was able to steal tokens nominally worth $50 million, lack of liquidity limited their profits to around $60,000. A blockchain called MANTRA also halted due to an exploit, but the network said that no user funds were impacted.
$1.76 million stolen from MAYAChain in attack exploiting six bugs
The Maya Protocol announced that an attacker had stolen 20 BTC (~$1.4 million) and various other assets totaling $1.76 million. A postmortem disclosed that the "sophisticated attacker exploited six chained bugs" to steal the assets. "The bugs exploited were not caught by Halborn audit, nor Fable 5 audit", wrote Maya founder on Twitter. Halborn is a blockchain security firm; Fable 5 is an AI model developed by Anthropic.
42DAO's Balance Coin algorithmic stablecoin crashes after $912,000 theft
Balance Coin, a small algorithmic stablecoin built on BNB Chain, lost its dollar peg and crashed to fractions of a cent after an attacker successfully exploited a flaw in its pricing logic. The attacker was able to trick the system into accepting an incorrectly low bitcoin price, which they then used to drain multiple vaults used by the project's lending protocol.
The attacker ultimately profited by about $912,000, consisting of funds stolen from 42DAO, the entity that runs the Balance protocol.
Allbridge exploited for $1.66 million
The Allbridge blockchain bridge was exploited for $1.66 million in a flash loan attack. The attacker took advantage of a flaw in the project's logic that reprices assets against one another, after discovering that the same would happen even when borrowing an asset against collateral denominated in the same token. They were able to manipulate the project's internal pricing logic so that the asset's actual price diverged away from reality, pocketing $1.66 million in proceeds.
Ostium loses at least $24 million to oracle exploit
![A circle overlaid with ][ symbols, followed by "Ostium" in orange capitals](https://primary-cdn.web3isgoinggreat.com/entryImages/logos/resized/ostium_300.webp)
Decentralized perpetual futures exchange Ostium was drained of at least $24 million after an attacker manipulated its oracle system — a system that pulls in off-chain price data. After the attacker apparently gained access to the private key used to sign oracle messages, they were able to submit future-dated oracle reports that tricked the system into thinking trades were profitable.
The attacker siphoned at least $24 million USDC from the protocol, which they quickly swapped into ETH and laundered via Tornado Cash.
Bonzo Lend exploited for $9 million in oracle attack
The Hedera-based decentralized lending platform Bozno Lend was exploited for just over $9 million after an attacker took advantage of a flaw in the project's oracle system. The attacker was able to deposit tokens worth only a few dollars, then manipulate the project's oracle to reflect a dramatically higher price. They then borrowed $6.63 million in USDC and 34.5 million wrapped HBAR (~$2.4 million).
Bonzo has announced they will reimburse users affected by the exploit, with support from the Hedera Foundation.
Summer Finance exploited for $6 million, shuts down
Summer Finance, a defi platform that provides "institutional defi vault infrastructure", was exploited for $6 million in an apparent flash loan attack. The attacker used a flash loan to deposit $64.8 million and then withdraw $70.9 million, taking advantage of a price manipulation bug that allowed them to withdraw more than they deposited.
Shortly after the exploit, Summer Finance announced it had "no viable path forward other than to wind down operations". They added, "a meaningful portion of the team's own capital was held in the affected vaults, removing the runway we needed to rebuild."
