The Best Temporary Email Services We've Tested for 2026
PCMag's hands-on roundup of the top disposable email services — tested for privacy, ease of use, and how well they protect your real inbox from spam and data brokers.
VPN Kill Switches, Leak Tests, and No-Log Audits: What the Best VPNs of 2026 Actually Proved
WIRED's engineers put six leading VPNs through a gauntlet beyond marketing claims: WireGuard vs. OpenVPN handshake latency under packet loss, DNS/IPv6 leak detection using Wireshark captures, kill-switch behavior during sudden interface drops, and whether each provider's no-log policy survived a real court subpoena or independent audit by a Big Four firm. We expose which 'no-log' VPNs still collect connection timestamps, how split-tunneling can silently expose your real IP to certain apps, and why pairing a VPN with disposable email identities closes the last gap advertisers exploit.
The Data Broker Ecosystem Exposed: How Your PII Is Bought, Sold, and Used Against You
EFF researchers trace a single email address through 47 data brokers — mapping how it's enriched with physical address, income bracket, political affiliation, health inferences, and a shadow credit profile before being sold to insurers, law enforcement agencies, and political campaigns. The investigation reveals the technical pipeline: email hashing for cross-site identity resolution, device graph linking, and probabilistic matching that reconnects anonymized records to real identities. Using a burner email from day one is the only reliable way to prevent your identity from entering this pipeline.

End-to-End Email Encryption in 2026: S/MIME, PGP, and Zero-Knowledge Vaults Tested
A deep-dive into how modern email encryption actually works under the hood — from OpenPGP key exchange and S/MIME certificate chains to zero-knowledge architectures used by ProtonMail and Tutanota. We benchmark decryption speed, audit key-management UX, and reveal which services expose metadata even when message content is encrypted. Includes threat-model analysis for journalists, whistleblowers, and everyday users who want genuine confidentiality, not just a green padlock.
Inside a Ransomware Attack: How Threat Actors Move Laterally and Exfiltrate Data
Krebs on Security reconstructs a real 2025 ransomware intrusion from initial phishing email to double-extortion demand — mapping each MITRE ATT&CK stage: initial access via malicious macro, privilege escalation using a Kerberoasting attack, lateral movement through stolen NTLM hashes, and data staging before encryption. Learn how defenders detect dwell-time indicators, why temporary email addresses are a critical early indicator of compromise, and what network segmentation strategies actually stopped the attack.
Browser Fingerprinting in 2026: How Advertisers Track You Without Cookies
Ars Technica's security team reverse-engineers the latest canvas fingerprinting, WebGL entropy harvesting, and AudioContext timing attacks used to uniquely identify browsers across sessions — even in private mode. We show the raw JavaScript, explain how entropy bits are combined into a stable 128-bit device ID, and test which browsers and extensions (Firefox + uBlock Origin vs. Brave vs. Tor Browser) actually defeat cross-site tracking. Disposable identities — including burner email addresses — are the last line of defense when fingerprints persist.
