<h4>DeFi is a great crypto space to be in. However, one of its downsides is the hacks and exploits. In 2023 alone, DeFi already lost $1.3 billion. More than 50% was during Q3, totaling $758 million. </h4> 
This spread out over 116 cases. The De.Fi platform published a <a href="https://de.fi/blog/de-fi-rekt-report-over-758m-lost-in-q3-2023" target="_blank" rel="noopener">report</a> about Q3’s DeFi exploits. So, we’re going to take a closer look at this DeFi report by De.Fi and recap it.

<h5>What Are the Exploit Trends in DeFi?</h5> 
There’s an uptrend in DeFi exploits. There were 166 cases in Q3-2023. During the same Q3-2022, there were 110 cases. These cases consisted of scams, exploits, and sometimes also unintended losses.&nbsp; 
However, the top three cases stood out. They combined around 64% for Q3 23 with $484 million. For instance: 
<ul> 
 <li style="font-weight: 400;">Multichain saw losses of $231.1 million.</li> 
 <li style="font-weight: 400;">The Mixin Network saw $200 million in losses.</li> 
 <li style="font-weight: 400;">CoinEx had a $52.8 million loss.</li> 
</ul> 
Access Control was the biggest culprit, with $319 million. It should come as no surprise that most losses are incurred on <a href="https://www.altcoinbuzz.io/?s=ethereum" target="_blank" rel="noopener">Ethereum</a>. It’s the biggest chain in DeFi after all. Likewise, it accounted for 48.7% of all losses in Q3-2023. This involved 72 of the 116 cases. The BNB-Chain came in second with #13.5 million, while CEXes ‘only’ lost $37 million. Newer chains and L2s, like Arbitrum or Optimism, also saw losses. However, they were not as significant as Ethereum or BNB.

<h5>The Most Common Exploits</h5> 
Rug pulls were the most common exploit. Q3 saw 78 rug pulls with $ $49.8 in losses. On the other hand, Access Control saw only 6 cases. However, these cases counted for $319 million, or 42%! Reentrancy attacks make up for 8 cases and $65.8 million in losses. This is when a bad actor keeps exploiting the victim’s smart contract, until it’s empty. There were also 12 incidents with General Exploits, causing $82.2 million damage. On a lesser scale, but still worth mentioning, there were, for example: 
<ul> 
 <li>Flash loan attacks.</li> 
 <li>Honeypots.</li> 
 <li>Phishing.&nbsp;</li> 
 <li>Oracle issues.</li> 
</ul>

<h5>What Are the Attack Vectors?</h5> 
Tokens were the prime target of all attack vectors. This vector saw a total of 80 cases. Exchanges were next in line, with 8 cases. These were mostly DEXes. Lending and borrowing protocols had a total of 4 cases. Furthermore, the emerging gaming and metaverse space saw a single case. However, this was a significant case.&nbsp; 
On the recovery side, there’s plenty of room for improvement. In Q3, there was only $8 million recovered. The space needs other platforms or measures to track and recover funds. The <a href="https://lossless.io/" target="_blank" rel="noopener">Lossless Protocol </a>comes to mind. It provides features that can detect shady transactions.

<h5>Q3-2023 Top Cases</h5> 
Let’s take a look at some top cases during Q3. 
<ul> 
 <li>Multichain $231 million</li> 
</ul> 
<a href="https://www.altcoinbuzz.io/cryptocurrency-news/the-latest-update-about-multichains-liquidity-crisis/" target="_blank" rel="noopener">Multichain</a> was one of the big cross-chain bridge operators in the DeFi space. However, it saw exploits totaling $231 million. It also appears that this may have been a rug. The Chinese police first arrested the CEO, Zhaojun. Later, they also arrested his sister.&nbsp; 
Somebody withdrew $125 million, with $120 from the Fantom bridge. For more details, check this report from <a href="https://www.chainalysis.com/blog/multichain-exploit-july-2023/" target="_blank" rel="noopener">Chainalysis</a>. Multichain ceased operations after these incidents.

<ul> 
 <li>Mixin Network $200 million</li> 
</ul> 
In September 2023, the <a href="https://mixin.one/" target="_blank" rel="noopener">Mixin Network</a> experienced an exploit. The platform lost a staggering $200 million. The attacker was well-skilled. He looked for specific vulnerabilities. He found these in the database of the network’s cloud service provider.&nbsp; 
This had some serious and immediate impact. It resulted in the platform suspending all withdrawals and deposits. The native XIN token slumped by 8%.

<ul> 
 <li>CoinEx $52.8 million</li> 
</ul> 
<a href="https://www.coinex.com/es" target="_blank" rel="noopener">CoinEx</a> is a trading platform. They lost $52.8 million in September 2023. The bad actors managed to compromise the private keys of the platform’s hot wallets. In total, they exploited 9 different chains. 
<ul> 
 <li>Vyper $50.5 million</li> 
</ul> 
<a href="https://docs.vyperlang.org/en/stable/" target="_blank" rel="noopener">Vyper</a> is a compiler. This is a tool, needed to write smart contracts. However, there were a few Vyper versions that had a weak point. The attacker exposed these successfully. As a result, various projects lost funds, to the tune of $50.5 million. However, $6.8 million of the stolen funds was recouped. 
<ul> 
 <li>Stake $41.4 million</li> 
</ul> 
<a href="http://www.stake.com" target="_blank" rel="noopener">Stake</a> is a gambling platform. It also took a hit in September 2023. Once again, the bad actors managed to get control over the hot wallets’ private keys. As a result, they could attack various networks. For instance, Ethereum, BNB, and Polygon. This resulted in siphoning a wide token range from the platform. The bad actor still had $13 million sitting on the 3 chains in October.
