Blast

<p class="is-style-lead">A smart contract security marketplace Code4arena appears to be the latest victim of a SIM swap attack on X.</p>
<p>An X account for Code4arena, a smart contract auditing platform, was compromised allowing a hacker to publish a scam post luring people to believe an airdrop was endorsed by a venture capital firm.</p>
<p>In an X <a href="https://twitter.com/code4rena/status/1729282511325348237" target="_blank" rel="noopener noreferrer nofollow">post</a> that appeared on Nov. 27, 2023 the hacker published a post announcing an airdrop of ARENA tokens endorsed by Paradigm, a San Francisco-based crypto venture capital investment firm.</p>

<p>The scale of the hack is not immediately clear as no public statements from Code4arena have been made so far. According to external <a href="https://x.com/CryptoMedic4/status/1729289686059766236?s=20" target="_blank" rel="noopener noreferrer nofollow">reports</a>, however, the incident was the result of a SIM-swap attack.

<p>The attack comes only days after cybersecurity experts recently raised concerns regarding the safety of Blast, a new layer-2 network aimed at reducing transaction costs for digital collectibles. On Nov. 24, Blast said in an X&nbsp;<a href="https://twitter.com/Blast_L2/status/1728096090204041587" target="_blank" rel="noopener noreferrer nofollow">thread</a> that no contract code security is completely airtight and that each smart contract design has its own associated vulnerabilities.</p>
