<div>
 <p>Ethereum is facing a rise in <strong>address poisoning scams</strong>, exploiting the recent <strong>Fusaka upgrade</strong>. The scams involve small "dust" transactions poisoning transaction histories.</p>
 <p><strong>Researchers</strong> such as <a href="https://twitter.com/LeonWaidmann/status/2012883942995525906" rel="noopener noreferrer nofollow">Andrey Sergeenkov</a> warn against these attacks which involve creating addresses that mimic victims'. Victims often fail to verify these addresses, inadvertently sending funds to the attackers.</p>

 <p>The <strong>financial impact</strong> includes $740K in stablecoin losses; broader address poisoning is part of $3.4B scam losses in 2025.</p>
 <p>Experts emphasize the <strong>irreversible nature</strong> of blockchain transactions, highlighting the <a href="https://dl.acm.org/doi/10.1145/3658644.3690277" rel="noopener noreferrer nofollow">need for stringent checks</a> by wallet users and operators to mitigate risks.</p>

<div>
 <p>Address poisoning has been noted since 2022, with a <strong>CMU study documenting</strong> 270 million attacks and $83.8M in losses over two years. <strong>Tsuchiya</strong>, Carnegie Mellon CyLab Researcher, remarked, "The important issue here is that blockchain transactions are not reversible. Once you make a mistake, you won’t be able to recover anything."</p>
 <p>Channelcoin experts predict continued threats due to <a href="https://www.cylab.cmu.edu/news/2026/01/07-blockchain-address-poisoning.html" rel="noopener noreferrer nofollow">shared address formats</a> and suggest monitoring user education on transaction security as a critical measure.</p>
