Researcher Eric Lu posted a 130-digit number on social media, asserting it divides the RSA-260 challenge integer, which would be the largest such number ever factored. He reportedly achieved this without AI, using only pencil and paper, though some conflicting reports mention the AI tool Devin. The claim, if verified, highlights the ongoing vulnerability of RSA encryption, though RSA-260 is far smaller than keys used in modern systems.
