Parallel Internet Privacy, PHP Vulnerability Risks and Security Industry Deals

Summary

Barrett Lyon discusses Doxnet’s privacy-focused network and VPN trust risks. The panel also examines PHP vulnerability remediation, Zeebra’s closure after two breaches, and cybersecurity acquisitions.

Key points

Doxnet founder Barrett Lyon described an encrypted mesh network with peer-to-peer communications, configurable firewall rules and optional onion routing.
Lyon said hardware providers he approached collected network-flow data and declined to sign his proposed data-handling agreement; the transcript does not independently verify the claim.
The panel discussed a PHP remote-code-execution vulnerability and the difficulty of patching older applications and appliances. Speakers cautioned that upgrading legacy PHP installations could break dependencies.
The hosts reported that Zeebra shut down after two breaches; they said approximately 3 million records were accessed in the second incident and some passwords had not been rotated after the first.
The panel discussed Thoma Bravo’s $6.3 billion acquisition of Varonis for combination with Proofpoint, noting overlap in their data-protection offerings.
Speakers reported Cohere’s acquisition of security firm Isle and Anthropic’s acquisition of Opaque Systems; they described a potential OpenAI acquisition of Trail of Bits as a rumor.
