<p>A bitcoin-focused DeFi protocol, BadgerDAO, had its web server compromised for roughly two weeks, allowing an unknown attacker to surreptitiously steal millions of dollars worth of digital assets from users of the platform, <a href="https://cms.blockworks.co/hackers-drain-115-million-from-bitcoin-defi-focused-badgerdao/" target="_blank" rel="noreferrer noopener">Blockworks reported</a>.</p>



<p>On Sunday, representatives of the DAO attempted to contact the party responsible for the theft using a message <a href="https://etherscan.io/tx/0xe0bf600d62e99f2f7b0bd6ce27a7167b8c04bd5a06727155c0334ca5c39dfd6c" target="_blank" rel="noreferrer noopener">published in a transaction on the Ethereum</a> network and on Twitter:</p>

<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p><strong>&#8220;Smart Contracts have not yet been reactivated and therefore users remain unable to deposit, claim rewards, or withdraw from either the Badger app (app.badger.com) or at the smart contract level.

<p>The system has a &#8220;Guardian&#8221; role, that has permission to pause the DeFi strategies employed by the protocol, which is &#8220;intended to be a trusted party that can act fast in emergency situations,&#8221; according to the <a href="https://docs.badger.com/badger-finance/technical/setts/base#variables" target="_blank" rel="noreferrer noopener">Badger.com documentation</a>. The Guardian is controlled by a developer multi-signature wallet, whose five members are elected by the DAO&#8217;s BADGER token holders. Any single member of the multisig can pause the smart contracts, but it requires three out of the five signers to reactivate them.</p>



<p>Security company PeckShield <a href="https://twitter.com/peckshield/status/1466356911842856967" target="_blank" rel="noreferrer noopener">reports the total loss</a> to BadgerDAO&#8217;s users at $120.3 million, based primarily on the theft of 2,100 BTC and 151 ETH. The largest affected user of the protocol <a href="https://cms.blockworks.co/celsius-reportedly-affected-in-exploit-of-defi-protocol-badgerdao/" target="_blank" rel="noreferrer noopener">has been linked</a> to cryptocurrency lending platform Celsius.</p>

<p>The Wednesday $115 million hack to the bitcoin-focused DeFi protocol BadgerDAO appears to have impacted Celsius Network to the tune of approximately $54 million, according to on-chain data from <a href="https://etherscan.io/tx/0x951babdddbfbbba81bbbb7991a959d9815e80cc5d9418d10e692f41541029869" target="_blank" rel="noreferrer noopener">etherscan</a>.</p>



<p>While the on-chain data does not definitively prove that the funds belonged to the crypto lender, the wallet that was impacted was seeded by a series of wallets that originates with Celsius.</p>



<p>Initial reports showed that a wallet linked to Celsius had 896 wrapped bitcoins stolen.</p>



<p>Celsius’ losses at this time could amount to approximately $54 million USD, a little under one-half of the total amount <a href="https://cms.blockworks.co/hackers-drain-115-million-from-bitcoin-defi-focused-badgerdao/" target="_blank" rel="noreferrer noopener">stolen</a> from BadgerDAO.</p>

<p>When Blockworks reached out to Celsius CEO Alex Mashinsky for comment on Thursday evening he said the company would provide a statement on Friday, but did not comment further.</p>



<p>On Friday, Celsius released a <a href="https://twitter.com/celsiusnetwork/status/1466833049014972422?s=21">series of Tweets</a>, addressing the hack. “No Celsius client and user assets were affected,” the company wrote.</p>



<p>BadgerDAO has hired data forensic experts Chainalysis to investigate the hack and is progressing with internal and external investigations, according to a recent tweet.</p>

<p>“As of right now, we have nothing further to share outside of the recent post. We will continue to provide updates as they come available,” a BadgerDAO admin said to Blockworks Thursday night.</p>



<p>As Blockworks reported early Thursday, the hack on BadgerDAO didn’t appear to be an attack on the protocol itself. Instead, the hackers went after the web interface connecting the protocol to the users’ wallets.&nbsp;</p>



<p>Many BadgerDAO Discord users reported that when their wallets interacted with BadgerDAO, they were hit with requests for additional permissions and then transferred tokens to wallets controlled by the hackers, Blockworks reported.</p>



<p>As with many cryptocurrency companies, neither BadgerDAO nor Celsius are federally regulated banks or FDIC-insured.</p>



<p>It’s been a wild two weeks for Celsius. On Nov. 24, the company <a href="https://cms.blockworks.co/celsius-expands-its-series-b-from-400m-to-oversubscribed-750m/" target="_blank" rel="noreferrer noopener">announced</a> it had expanded its Series B From $400 million to an oversubscribed $750 million.

Celsius Reportedly Affected in Exploit of DeFi Protocol BadgerDAO

        <ul>

            </ul>
    
</div>



<p>Another DeFi protocol has fallen victim to an eight-figure hack, as Badger DAO reports that it has noticed “unauthorized withdrawals” from its protocol.&nbsp;</p>



<figure class="wp-block-embed is-type-rich is-provider-twitter wp-block-embed-twitter"><div class="wp-block-embed__wrapper">
<blockquote class="twitter-tweet" data-width="550" data-dnt="true"><p lang="en" dir="ltr">Badger has received reports of unauthorized withdrawals of user funds.<br><br>As Badger engineers investigate this, all smart contracts have been paused to prevent further withdrawals.<br><br>Our investigation is ongoing and we will release further information as soon as possible.</p>&mdash; ₿adgerDAO 🦡 (@BadgerDAO) <a href="https://twitter.com/BadgerDAO/status/1466263899498377218?ref_src=twsrc%5Etfw">December 2, 2021</a></blockquote><script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script>
</div></figure>



<p>BadgerDAO initially reported that $10 million had been pilfered, though reports from blockchain security and analytics company <a href="https://twitter.com/peckshield/status/1466350031288500227">PeckShield puts that number</a> closer to $115 million, over 2,063 bitcoins. One unlucky user <a href="https://twitter.com/peckshield/status/1466294179676372992" target="_blank" rel="noreferrer noopener">lost 900 bitcoin</a>.&nbsp;</p>



<p>BadgerDAO’s mission, as it describes it, is to “bring Bitcoin to DeFi” by creating various <a href="https://cms.blockworks.co/wrapped-crypto-tokens-and-why-theyre-critical-to-markets/">wrapped bitcoin</a> products. </p>



<p>Unlike many other hacks of DeFi protocols, this one doesn’t appear to be an attack on the protocol itself, but rather the web interface connecting the protocol to the users’ wallets to the protocol.&nbsp;</p>



<p>On <a href="https://discord.com/invite/xSPFHHS" target="_blank" rel="noreferrer noopener">the BadgerDAO Discord</a>, many users complained that when their wallets interacted with BadgerDAO they were hit with requests for additional permissions and then transferred tokens to wallets controlled by the hackers.&nbsp;</p>



<p>“It looks like a bunch of users had approvals set for the exploit address allowing it to operate on their vault funds and that was exploited,” Badger developer Tritium wrote on Discord.&nbsp;</p>



<p>Currently, BadgerDAO has decided to pause all smart contracts to prevent further withdrawals as it investigates further.&nbsp;</p>



<p>BadgerDAO’s governance token BADGER is down sharply on the news.</p>

<p>The founder of BadgerDAO, Chris Spadafora, who goes by the moniker SpadaBoom (with the &#8216;B&#8217; as a Bitcoin symbol), announced that the smart contracts would remain paused, preventing withdrawals from the protocol.</p>



<p>&#8220;Badger has retained data forensics experts Chainalysis to explore the full scale of the incident and authorities in both the US and Canada have been informed and Badger is cooperating fully with external investigations as well as proceeding with its own,&#8221; Spadaboom wrote on Discord Thursday evening (ET).</p>



<p>Token holders <a href="https://badger.com/governance" target="_blank" rel="noreferrer noopener">are responsible for approving changes</a> to the decentralized protocol on Ethereum, but the <a href="https://badger.com/" target="_blank" rel="noreferrer noopener">Badger.com</a> frontend is separate from the project&#8217;s Ethereum smart contracts, and the core team retains some administrative powers.</p>



<p>According to Badger Core team member Mitche50, commenting on the BadgerDAO Discord&#8217;s &#8220;general&#8221; channel:</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p><strong>“It looks like an API key for cloudflare was compromised. Through this, the hacker was able to create a script, inject the script into custom routes and serve the frontend with the malicious script injected.”</strong></p></blockquote>



<p>Cloudflare is a widely used American website infrastructure company that provides content delivery network and helps sites defend against denial-of-service attacks.</p>



<p>Among the unresolved questions are, how long has this exploit been operative, and why did it go undetected? Mitche50 told Blockworks, “the investigation of exactly what happened is still ongoing.”</p>



<p>It’s also unclear, whether the affected users will be able to be compensated for losses by the DAO, or by insurance protocol Nexus Mutual, which offers insurance on BadgerDAO, currently at a rate of 2.6% annually.</p>



<p>The insurers’ <a href="https://app.nexusmutual.io/cover/buy/get-quote?address=0x6354E79F21B56C11f48bcD7c451BE456D7102A36" target="_blank" rel="noreferrer noopener">term and conditions</a> note that insurance covers only “contract bugs, economic attacks, including oracle failures [and] governance attacks,” and Nexus’ own governance may determine the present exploit is outside the scope of coverage.</p>



<p>The Nexus team issued a statement in <a href="https://discord.gg/aQjkzW5" target="_blank" rel="noreferrer noopener">their Discord&#8217;s</a> &#8220;claims-discussions&#8221; channel indicating that BadgerDAO cover holders may be out of luck in this case:</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p><strong>&#8220;If this is confirmed as a frontend attack, BadgerDAO’s smart contracts were not impacted and this would not be a covered event.</strong></p><p><strong>Frontend attacks are not covered per section 9 of the <a href="https://nexusmutual.io/pages/ProtocolCoverv1.0.pdf" target="_blank" rel="noreferrer noopener">Protocol Cover wording</a>.&#8221;</strong></p></blockquote>



<p>Even if Nexus were to include the hack as a covered event, as of today, less than $14.25 million in coverage was purchased, according to <a href="https://nexustracker.io" target="_blank" rel="noreferrer noopener">nexustracker.io</a>.</p>



<p>BadgerDAO launched its first launched yield-generating vaults based on wrapped bitcoin on Ethereum, in December 2020. The project quickly moved to community-based governance through the distribution of the BADGER token, which has been used to vote on over 70 improvements to the protocol since launch.</p>



<p>BadgerDAO&#8217;s total value locked peaked in February at $2.32 billion, but the protocol still has $1.1 billion in assets, <a href="https://defillama.com/protocol/badger-dao" target="_blank" rel="noreferrer noopener">according to DeFi Llama</a>.</p>



<p>While this hack is significant, it pales in comparison to some of the largest successful exploits that have occurred against DeFi protocols this year. For instancce, in August, hackers made off with nearly <a href="https://cms.blockworks.co/hackers-steal-over-600m-biggest-in-defi-history/" target="_blank" rel="noreferrer noopener">$600 million after they exploited bugs</a> in the Poly Network.</p>



<p><em>This story was updated on December 2, 2021 at 12:10 pm ET with a statement from Nexus Mutual. The headline was updated to clarify that funds were not drained from the BadgerDAO protocol itself, but directly from users of the Badger.com frontend.</em></p>



<p><em>This story was updated on December 3, 2021 at 3:30 AM to include a comment from BadgerDAO founder Chris Spadafora.</em></p>
