Researchers Use Claude to Port Pre-Auth RCE Exploit From One PLC Model to Another

Forescout used Anthropic's Claude to port a working pre-auth RCE exploit for CVE-2021-31886 between WAGO PLCs, executing ARM shellcode on live hardware.

Forescout Vedere Labs used Claude interactively to port an RCE exploit for CVE-2021-31886, a CVSS 9.8 stack buffer overflow in the Nucleus FTP server's USER command, from a WAGO 750-852 to a WAGO 750-831 PLC, running attacker-supplied ARM shellcode. The final RCE stage cost $535.74 in API usage over 8 hours 32 minutes, and a follow-up attempt to build a C2 implant permanently bricked the device. CERT@VDE lists many Nucleus V1-based WAGO models as vulnerable with no updates available; Siemens plans no Nucleus NET remediation. The work follows a joint NSA/CISA/FBI/DOE/EPA advisory warning of AI-generated exploitation scripts targeting internet-exposed Siemens S7 PLCs.

Phishing Powers 80% of Attacks on US Companies: How SOCs Can Detect It Early

Phishing drives 80% of attacks on US companies; FBI recorded 158,436 BEC victims and over $20B in losses from 2013-2023.

A vendor-authored analysis claims phishing powers roughly 80% of attacks on US companies, citing FBI statistics of 158,436 business email compromise victims and more than $20 billion in reported losses between 2013 and 2023. It describes modern phishing using compromised infrastructure, redirect chains, dynamic pages, and adversary-in-the-middle techniques, including a recent campaign targeting tens of thousands of primarily US users. The piece promotes ANY.RUN Threat Intelligence Feeds and TI Reports, claiming 99% unique high-confidence IOCs, 21-minute faster MTTR, and 30% fewer Tier 2 escalations.

Forgery of C2PA on a Pixel 10

Researcher forged a Google Pixel 10 C2PA content credential with genuine signatures, showing root-level attackers can fake photo provenance.

A Hacker Factor blog post demonstrates an AI-generated 'unicorn glitter milk' news photo carrying a valid, cryptographically signed C2PA manifest traceable to Google's Pixel camera certificate chain, passing validation in Adobe Inspect and the CAI Verify tool with a verified timestamp. The author, working with UMBC's PASAWG working group, reported to Google and C2PA in November 2025 that root access on a Pixel device could sign arbitrary images as camera captures; after 90 days without resolution, details were published. The finding undermines C2PA Assurance Level 2 claims made for Pixel 10 Content Credentials.

Data Broker Radaris Loses Domains in Privacy Fight

A New Jersey court ordered people-search broker Radaris to transfer radaris.com and a dozen related domains to Atlas Data Privacy over Daniel's Law violations.

On August 26, a New Jersey judge found Radaris failed to defend claims that it violated Daniel's Law, which protects law enforcement officials' personal data and imposes $1,000 fines per ignored removal request. The court ordered radaris.com and more than a dozen related broker domains transferred to plaintiff Atlas Data Privacy Corp. Radaris had delayed litigation using offshore shell entities and previously used a fictitious CEO named 'Gary Norden' in investor-facing press releases.

Microsoft Excel KB5002914 update breaks copy and paste for some users

Microsoft's September Patch Tuesday update KB5002914 breaks copy-and-paste and formula dragging in Excel 2016 through 2024; uninstalling the update restores functionality.

Users on Reddit and Microsoft Q&A report that the KB5002914 security update shipped in the September 2026 Patch Tuesday breaks copy-and-paste, autofill, and formula dragging in Excel. The problem spans Office 2016 through 2024 across MSI and Click-to-Run installations, including Office LTSC Standard 2021, with some teams blocked after widespread patching. Uninstalling KB5002914 or downgrading the Office build restores functionality, though replacing the excel.exe binary is not recommended. BleepingComputer could not reproduce the issue on Excel 2019 Version 2508 Build 19127.20302 and contacted Microsoft for comment.
