Balancer Hack: A Masterclass in Stealth and Planning (And We Almost Didn’t Notice!)

by

In a twist of fate that only a seasoned villain could orchestrate, the $116 million hack of the Balancer platform has been unearthed as the work of a highly skilled, ultra-patient attacker. Months of careful preparation, combined with a near-perfect execution, led to the breach of the decentralized exchange (DEX) and automated market maker (AMM) on Monday, and the crypto world is left in stunned awe.

Blockchain data reveals that the thief wasn’t your average amateur. Oh no, this was someone who planned like a chess master, funding their account with small, sneaky 0.1 Ether (ETH) deposits using the notorious privacy mixer Tornado Cash. It was like they were taking a meticulous little walk through a garden of crypto, planting tiny seeds to grow a vast fortune. How cute-and how terrifying. 🙄

Conor Grogan, a director at Coinbase (you know, just a small-time crypto exchange), pointed out that this particular hacker had a whopping 100 ETH stored in Tornado Cash smart contracts-oh, and this was likely the result of previous hacks. Maybe they’d just been waiting for their big moment? Just a hunch.

“The hacker seems experienced: 1. Seeding account with 100 ETH and 0.1 ETH from Tornado Cash deposits. No opsec leaks. Very neat, very clean,” Grogan remarked with an eye roll in a Monday X post. “Since there were no recent 100 ETH deposits to Tornado Cash, it seems likely the exploiter had funds there from earlier escapades. Of course, just another Tuesday for them.”

Oh, and users rarely store such substantial sums in mixers-because, you know, it’s not exactly “normal” to play hide and seek with that much crypto. It’s almost like the attacker knew exactly what they were doing. Fancy that! crypto stealth

In a surprising twist (I know, you were not expecting this at all), Balancer offered a 20% “white hat” bounty if the stolen funds were returned by Wednesday. Because, sure, why wouldn’t a professional criminal be interested in a good old-fashioned reward for doing the right thing? 🙄

“Our team is working with leading security researchers to understand the issue and will share additional findings and a full post-mortem as soon as possible,” said Balancer, still processing the fact that this hack probably cost them more than an entire year’s worth of holiday bonuses.

Balancer Exploit: The Most Sophisticated Attack of 2025? 🤔

According to Deddy Lavid, co-founder and CEO of blockchain security firm Cyvers, the Balancer exploit ranks as one of the “most sophisticated attacks we’ve seen this year.” Bold statement, but let’s be real-it’s hard to argue with the facts.

“The attackers bypassed access control layers to manipulate asset balances directly. This wasn’t a flaw in the core protocol. It’s a catastrophic failure in operational governance. Who’s in charge here?”

Lavid continued to raise the alarm, calling for continuous, real-time monitoring to spot suspicious flows before funds vanish into the abyss-because static audits, it seems, are no longer enough. So much for good ol’ fashioned code reviews. hacker's precision

Lazarus Group: A Lesson in How to Pause Before Stealing $1.4 Billion

Speaking of masterminds, let’s talk about the Lazarus Group, North Korea’s favorite bunch of cyber criminals, who are known for their oh-so-thorough planning before they go on their little hacking binges. According to blockchain analytics firm Chainalysis, their illicit activity slowed dramatically after July 1, 2024, likely as they carefully regrouped and chose new targets for their next big heist.

Because, of course, this is just how North Korean hackers do things. They don’t rush-they plan. Why go for an easy win when you can be the Picasso of crypto crime?

“The slowdown we observed could have been a strategic regrouping to probe infrastructure, or, you know, just reworking the whole scheme like a fine-tuned orchestra,” said Eric Jardine, Chainalysis’ cybercrimes research lead. Ah, how considerate of them.

It took Lazarus just 10 days to launder a cool $1.4 billion worth of stolen Bybit funds through the decentralized crosschain protocol THORChain. What a lovely little laundering vacation they must’ve had. 🧐
