Browser Tampering Surges as VPNs Gain Popularity
Fingerprint published its Device Intelligence Report analyzing 23.4 billion identification events from 7.3 billion unique browsers and devices. The report finds browser tampering nearly doubled year-over-year, with 4.4% of desktop identifications in 2025 showing tampering techniques, while mobile tampering remains below 1%. Desktop sessions show concentrated fraud signals (12% running in virtual machines, 6% with developer tools open) and automation that reaches 8% on desktop and is 96% associated with abuse. VPN use has grown to about one in five identification events across all traffic, shifting network privacy signals from suspicious behavior toward mainstream user privacy practice.
The report documents growing sophistication in device/browser manipulation and widespread VPN adoption, which materially affects fraud detection and identity signals used across AdTech and MarTech—important for fraud-prevention vendors and platforms but not a major platform policy change.

Report: Trojans and Online Fraud Surge in Germany
The Gen Threat Report H1 2026 shows a marked increase in cybercrime in Germany, with attackers shifting from classic malware to deception that exploits trusted platforms and processes. The report documents large percentage increases in droppers (+160%), trojans (+145%), and online-shop fraud (+134%), plus rises in remote access trojans (+69%) and phishing (+47%). Germany saw 2.3 million tech-support-fraud attacks blocked in the first half of 2026 (third highest globally). Globally, analysts blocked over 114 million fake-shop attacks and observed rising web-skimming, identity fraud, tracking attempts and misuse of AI agents as an emerging attack surface.
Session Hijacking: Cookie Theft Bypasses Two-Factor Authentication
The article explains session hijacking by cookie/theft of session tokens as a rapidly growing identity attack in 2026. Infostealer malware (e.g., RedLine, Raccoon, Lumma, Vidar) exfiltrates entire browser cookie stores and related credentials; those datasets—called “stealer logs”—appear on Telegram channels and dark‑web marketplaces. SpyCloud reports a 58% rise in infostealer infections and over 2.1 billion stolen cookie records. Google’s Threat Analysis Group says session token theft now causes more account takeovers than phishing, and Microsoft confirmed AiTM phishing kits plus session token theft drove a wave of enterprise compromises in early 2026. Because stolen cookies represent already-authenticated sessions, two‑factor authentication often cannot stop these attacks. Recommended protections include patching devices, using antivirus, logging out of sessions, clearing cookies, avoiding public Wi‑Fi or using a VPN, and adopting device‑bound or token‑binding session designs.
US suspends Microsoft, Adobe from green card labor program
The Trump administration has suspended Microsoft, Adobe, and six other major tech firms—Capgemini, Cognizant, HCL, Infosys, Tata, and Wipro—from the U.S. Permanent Labor Certification program, which facilitates green cards for skilled foreign workers. Secretary of Labor Keith Sonderling cited active federal investigations and alleged fraud, noting that no new or pending applications from these companies will be accepted. Vice President JD Vance accused Microsoft of replacing laid-off workers with H-1B visa holders. Microsoft defended its practices, stating that most U.S. employees are American and that 80% of its H-1B petitions were for existing employees. The announcement was made during a White House summit on H-1B fraud, and the administration also plans to investigate nine universities, including Harvard, Yale, and Stanford, over student visa program abuse.
