Aerodrome and Velodrome suffer website takeovers, again

Attackers redirected users intending to visit the websites for the decentralized exchanges Aerodrome and Velodrome to their own fraudulent versions using DNS hijacking, after taking control of the websites' domains. The platforms urged users not to visit the websites as they worked to regain control.

This is the second time such an attack has happened to these same platforms, with another DNS hijacking incident occurring almost exactly two years ago. In that instance, users lost around $100,000 when submitting transactions via the scam websites.

Cardano founder calls the FBI on a user who says his AI mistake caused a chainsplit

On November 21, the Cardano blockchain suffered a major chainsplit after someone created a transaction that exploited an old bug in Cardano node software, causing the chain to split. The person who submitted the transaction fessed up on Twitter, writing, "It started off as a 'let's see if I can reproduce the bad transaction' personal challenge and then I was dumb enough to rely on AI's instructions on how to block all traffic in/out of my Linux server without properly testing it on testnet first, and then watched in horror as the last block time on explorers froze."

Charles Hoskinson, the founder of Cardano, responded with a tweet boasting about how quickly the chain recovered from the catastrophic split, then accused the person of acting maliciously. "It was absolutely personal", Hoskinson wrote, adding that the person's public version of events was merely him "trying to walk it back because he knows the FBI is already involved". Hoskinson added, "There was a premeditated attack from a disgruntled [single pool operator] who spent months in the Fake Fred discord actively looking at ways to harm the brand and reputation of IOG. He targeted my personal pool and it resulted in disruption of the entire cardano network."

Hoskinson's decision to involve the FBI horrified some onlookers, including one other engineer at the company who publicly quit after the incident. They wrote, "I've fucked up pen testing in a major way once. I've seen my colleagues do the same. I didn't realize there was a risk of getting raided by the authorities because of that + saying mean things on the Internet."

GANA Payment hacked for $3.1 million

An attacker stole approximately $3.1 million from the BNB chain-based GANA Payment project. The thief laundered about $1 million of the stolen funds through Tornado Cash shortly after. The attacker was able transfer ownership of the GANA contract to themselves, possibly after a private key leak.

The theft was first observed by crypto sleuth zachxbt. Not long after, the project acknowledged on its Twitter account that "GANA's interaction contract has been targeted by an external attack, resulting in unauthorized asset theft."

Moonwell accrues almost $3.7 million of bad debt after oracle malfunction

The Moonwell lending protocol, built on the Base Ethereum L2, wound up with $3.7 million in bad debt after an attacker took advantage of an oracle malfunction that caused the price of wrsETH to be massively inflated. The Chainlink oracle used by the project erroneously reported that a single wrsETH token (Kelp DAO's wrapped restaked ETH) was priced at around 1.65 million ETH (~$5.8 billion). Within 30 seconds of the oracle reporting bad data, an attacker took advantage of the error to borrow huge amounts of tokens, which they then swapped to other tokens to cash out.

Ultimately the attacker profited around 295 ETH (~$1 million), but the protocol was saddled with significantly more bad debt that the team will now have to grapple with.

Stream Finance halts activity after $93 million loss

The Stream Finance defi yield project announced that "an external fund manager overseeing Stream funds disclosed the loss of approximately $93 million in Stream fund assets." Stream announced that they were in the process of withdrawing remaining liquid assets, and had halted all deposits or withdrawals. They also announced they had retained a law firm to investigate the "incident".

The project didn't disclose who the fund manager was, or the circumstances in which the "loss" occurred.

The Staked Stream USD token depegged on November 3, and crashed further following the announcement.

Balancer exploited for at least $110 million

The defi protocol Balancer suffered a major exploit that drained over $110 million across several blockchains, including Ethereum, Polygon, Base, and Sonic. Attackers exploited faulty access control in the manageUserBalance function of Balancer's v2 smart contract, enabling unauthorized internal withdrawals. The stolen tokens included 6,850 osETH, 6,590 wETH, and 4,260 wstETH, later consolidated into new wallets likely for laundering.

The exploit also impacted forked protocols like Beets Finance, which lost around $3 million. Balancer's BAL token dropped over 10% following the theft.

This was Balancer's third major security incident since 2020, despite prior audits by OpenZeppelin and Trail of Bits.

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.

Paxos accidentally mints more than twice the global GDP in PayPal stablecoins

Paxos, the issuer of PayPal's PYUSD stablecoin, accidentally minted 300 trillion of the supposedly dollar-pegged token. For context, this is approximately 2.5x the global GDP, and around 125x the total number of US dollars actually in circulation.

Paxos later announced that the mint was an "internal technical error", and that they had burned the excess tokens.

While PayPal promises its customers that "Reserves are held 100% in US dollar deposits, US treasuries and cash equivalents – meaning that customer funds are available for 1:1 redemption with Paxos," there clearly isn't much in the way of safeguards to ensure that is always the case. As with most stablecoin issuers, Paxos merely issues self-reported and unreviewed portfolio reports, and monthly third-party attestations (not audits) of reserves.

Hyperliquid user loses $21 million to private key leak

An attacker apparently obtained access to a victim's private key, enabling them to drain $21 million in various crypto assets. The attacker quickly bridged the stolen funds to ETH, then bounced through various addresses in hopes of disguising their origin and making the funds more challenging to recover.

Some originally feared that the theft was enabled by an exploit on Hyperliquid itself, shortly after another Hyperliquid-based project was compromised, but the theft appears to have been a key leak rather than an exploit on the protocol.

Abracadabra loses more "Magic Internet Money" to third hack in two years

In their third major hack in two years, the Abracadabra defi lending project lost $1.8 million of their Magic Internet Money stablecoin. An attacker took advantage of a bug in the project smart contracts to borrow more than their provided collateral would normally allow. The attack was funded via Tornado Cash, and the exploiter then swapped the stolen tokens for ETH and laundered them back through Tornado.

The project disclosed the theft, describing the exploit as affecting "some deprecated contracts". They downplayed the theft, saying they'd bought back the stolen assets using treasury funds.

Abracadabra previously suffered a $13 million theft in March 2025, and a $6.5 million theft in January 2024.
