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.

When Agents Look Like Beacons: NIDS Evasion by Model Context Protocol Traffic

Research shows Model Context Protocol agent traffic structurally resembles C2 beaconing and evades Suricata signatures and RITA behavioral scoring in testbeds.

An arXiv study demonstrates that Model Context Protocol (MCP) JSON-RPC traffic over Streamable HTTP mimics the polling patterns of C2 frameworks like Cobalt Strike and is not flagged as anomalous by standard enterprise defenses. In a Docker testbed with eleven traffic profiles across three TLS conditions, Suricata with the Emerging Threats Open ruleset produced near-zero alerts and RITA assigned a consistent 0.0 beacon score, regardless of jitter or TLS inspection. The authors propose an agent-native network indication standard using Agent-Native ALPN and out-of-band headers.

Webinar: How malicious OAuth apps can lead to Google Workspace breaches

BleepingComputer webinar will dissect two Google Workspace breaches caused by malicious OAuth apps and social engineering, hosted September 23 with Material Security.

On September 23, 2026, BleepingComputer will host a webinar with Material Security examining two real attacks that used malicious OAuth applications and social engineering to breach Google Workspace environments. Rather than stealing credentials, attackers persuaded users to authorize malicious apps, gaining access to data through the granted permissions. The session covers first-hour response decisions and which security controls provide the greatest value for fast-growing organizations.

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.
