Google Workspace Security Must Adapt to AI-Driven Threats
The traditional attack chain is getting a makeover: instead of starting with a malicious email, attackers now use OAuth apps to breach Google Workspace, exploiting new vulnerabilities in an AI-driven threat landscape. It's time to shift from an inbox-centric to an OAuth-first security approach to stay ahead.
Smaller AI Models Gain Hacker Edge
The tide is turning in the world of AI: smaller, more affordable models are suddenly delivering impressive results in hacking and exploitation benchmarks, providing net value at a cheaper price and giving them a competitive edge. This emerging middle class of AI models, including GLM-5.2, Grok 4.5, and Opus 4.7, is crossing a crucial threshold, making them strategic players in the industry.
US Grants Private Firms License to Hack Back Against Cybercrime Groups
The US government has just given private cybersecurity firms the green light to hack back against foreign cybercrime groups that threaten American interests, marking a major shift in the country's cyber warfare strategy. This bold move targets transnational crime groups, not nation-states, and paves the way for covert surveillance and cyber operations.
Researchers Discover Context Bombing Technique to Disrupt AI Hacking Agents
Researchers have discovered a clever way to shut down AI hacking agents by inserting specially crafted prompts alongside sensitive data on Amazon Web Services, effectively triggering the model's internal safety rules and halting attacks. This innovative technique, dubbed "context bombing," has proven to be a simple yet effective defense against AI-powered hacking.
Fake Chrome VPN Extensions Expose Users to Proxy Routing Risks
Beware of Chrome VPN extensions that may be putting your online security at risk: over 737 extensions impersonated popular VPN and proxy services, secretly routing users' traffic through unsecured SOCKS5 proxies. This exposed users to potential data breaches and surveillance, as their browsing activity was intercepted by a single, unknown provider.
Windows Plug and Play Feature Exploited for SYSTEM Access via Fake USB Devices
Imagine a scenario where hackers can gain SYSTEM access to a Windows computer without needing a single click or logged-in user - and even exploit it remotely over RDP with no hardware involved. Researchers have just revealed a chilling new class of attacks, dubbed "Plug and Pwn", that takes advantage of Windows' Plug and Play feature to execute malicious software with alarming ease.
Zoom Flaws Let Meeting Participants Hijack Other Attendees' Clients
Critical security flaws in Zoom's annotation code, tracked as CVE-2026-53413, CVE-2026-53414, and CVE-2026-53415, could have allowed a meeting participant to hijack others' clients without warning. Fortunately, Zoom has patched these vulnerabilities, and no exploitation has been reported.
