Finance Redefined: The Week in DeFi – A Roller Coaster of Exploits and Mishaps

Critical Ledger vulnerability threatens the entire DApp ecosystem Finance Redefined

Ledger vulnerability jeopardizes DApp ecosystem Finance Redefined

Welcome to Finance Redefined, your weekly ticket to the wild and wonderful world of decentralized finance (DeFi). Strap in, because this week’s ride was a roller coaster of exploits and mishaps that left us both shaken and stirred.

First up, let’s talk about the Ledger hack that threw the entire DApp ecosystem into a frenzy. A malicious actor exploited a vulnerability in the Ledger hardware wallet’s connector library, putting users at risk. On-chain analysts and DApps like SushiSwap and MetaMask were shouting from the virtual mountaintops, warning users not to touch their wallets with a ten-foot pole. Ledger, to their credit, released a patch faster than a cheetah on Red Bull, but the damage was done. The exploiter managed to siphon off over $650,000 in assets from multiple victims. It could have been worse, but hey, at least it’s not a billion dollars, right?

So how did this Ledger hacker pull off such a fiendish feat? Well, according to the crack team over at Cyvers, they tricked Web3 users into making malicious token approvals. It’s like convincing someone to open Pandora’s box and then stealing all the goodies inside. Talk about a modern-day swindle! Apparently, the attacker used a phishing exploit to compromise the computer of a former Ledger employee, gaining access to the employee’s node package manager javascript account. Sneaky, sneaky!

But that’s not all, folks. Ledger wasn’t the only one feeling the heat this week. Multiple decentralized applications (DApps) using Ledger’s connector library also got caught with their pants down. Zapper, SushiSwap, Phantom, Balancer, and Revoke.cash were all compromised. It was like a game of musical chairs gone wrong, with the malicious version of the file being replaced with the genuine one just in the nick of time. Ledger is now warning users to always “Clear Sign” transactions and to trust only what they see on their Ledger device. If your computer/phone screen is playing tricks on you, stop that transaction faster than a superhero saving the day.

And then there’s our dear friend Yearn.finance, hoping against hope that arbitrage traders will return $1.4 million in funds after a multisignature scripting error drained a large chunk of their treasury. Oopsie-daisy! It seems a faulty multisig script caused Yearn’s entire treasury balance to be swapped for… well, something undesirable. It’s like losing your wallet with all your cash inside, except on a multi-million-dollar scale. Yikes!

But wait, there’s more! The OKX DEX (decentralized exchange) suffered a $2.7 million hack, all because the private key of the proxy admin owner was leaked. It’s like leaving your front door wide open in a bad neighborhood. The user upgraded the DEX proxy contract, and boom, tokens started disappearing faster than a magician’s vanishing act.

So, what is the state of the DeFi market amidst this chaos? Surprisingly, the top 100 tokens by market capitalization had a bullish week, with most trading in the green. It’s like a garden of blooming flowers amidst a stormy sea. The total value locked into DeFi protocols remained above $60 billion, so there’s still gold in them hills.
