OWASP Mobile Top 10 for Android – How AutoSecT Detects Each Risk?

Mobile applications account for 70% of global interactions, with over 6.8 billion smartphone users. In 2023, 40% of data breaches are linked to vulnerabilities in mobile applications. The OWASP Mobile Top 10 outlines critical security risks for mobile apps, including: 1. Improper Credential Usage: Mishandling of passwords and session tokens. 2. Inadequate Supply Chain Security: Risks from unverified third-party components. 3. Insecure Authentication/Authorization: Failures in verifying user identities. 4. Insufficient Input/Output Validation: Lack of checks on incoming and outgoing data. 5. Insecure Communication: Unprotected data during transmission. 6. Inadequate Privacy Controls: Poor safeguards for personal data. 7. Insufficient Binary Protections: Lack of defenses against reverse engineering. 8. Security Misconfiguration: Improperly secured application settings. 9. Insecure Data Storage: Weak protection of sensitive information on devices. 10. Insufficient Cryptography: Use of weak or improperly implemented encryption. AutoSecT, an AI-driven mobile app security testing platform, detects these risks through various methods, including static code analysis, software composition analysis, and dynamic testing. It helps developers identify and mitigate vulnerabilities effectively.

Denial of Fuzzing: Rust in the Windows kernel

Check Point Research (CPR) identified a significant security vulnerability in the Rust-based kernel component of the Graphics Device Interface (GDI) in Windows, reported to Microsoft in January 2025. The issue was resolved in OS Build 26100.4202, part of the KB5058499 update released on May 28, 2025. The vulnerability was discovered during a fuzzing campaign targeting the Windows graphics component through metafiles, revealing multiple security issues including information disclosure and arbitrary code execution. The specific bug was linked to a crash occurring during the execution of a NtGdiSelectClipPath syscall in the win32kbasers.sys driver, triggered by an out-of-bounds memory access when processing malformed metafile records. Microsoft classified the vulnerability as moderate severity and addressed it in a non-security update, implementing substantial changes to the affected kernel module.

Securing the Model Context Protocol: Building a safer agentic future on Windows

The Model Context Protocol (MCP) is a lightweight, open protocol functioning as JSON-RPC over HTTP, facilitating standardized discovery and invocation of tools. MCP defines three roles: MCP Hosts (applications accessing capabilities), MCP Clients (initiators of requests), and MCP Servers (services exposing functionalities). Windows 11 will incorporate MCP to enable developers to create intelligent applications leveraging generative AI. An early preview of MCP capabilities will be available for developer feedback. MCP introduces security risks, including cross-prompt injection, authentication gaps, credential leakage, tool poisoning, lack of containment, limited security review, registry risks, and command injection. To address these, Windows 11's MCP Security Architecture will establish security requirements for MCP servers, ensuring user safety and transparency, enforcing least privilege, and implementing security controls like proxy-mediated communication, tool-level authorization, a central server registry, and runtime isolation. MCP servers must comply with security requirements, including mandatory code signing, unchanged tool definitions at runtime, security testing, mandatory package identity, and declared privileges. An early private preview of MCP server capability will be offered to developers post-Microsoft Build for feedback, with a secure-by-default enforcement strategy planned for broader availability. Microsoft aims to enhance defenses continuously and collaborate with partners to bolster MCP's security framework.

Best antivirus software for Windows 2025, tried and tested

Antivirus software has been a common tool for PC users over the past two decades, with many opting for third-party solutions for enhanced protection despite Windows 11's built-in features. User behavior significantly impacts computer security, emphasizing the importance of avoiding unknown links and not reusing passwords. Antivirus packages are designed to combat threats like ransomware, spyware, and viruses. The evaluation process for antivirus applications involved testing on a Windows 11 PC with simulated virus attacks and scanning the SSD for performance metrics. The top antivirus apps for 2025 include BitDefender Total Security (£49.99), Avira Free (free), Malwarebytes Plus (£49.99), and Sophos Home Premium (£37.46).

Best antivirus software 2025, tried and tested

Antivirus software has been essential for PC users for two decades, with advertisements emphasizing its importance. Windows 11 includes built-in security features, but many users prefer third-party antivirus solutions for quicker updates and additional benefits. User behavior significantly impacts computer security, and it is recommended to avoid links from unfamiliar email senders and not to reuse passwords. A comprehensive evaluation of antivirus applications involved testing on a Windows 11 PC using simulated virus attacks. The testing included scanning the SSD and consulting independent security testing laboratories. The best antivirus software for 2025 includes BitDefender Total Security as the best overall, Avira Free as the best free option, Malwarebytes Plus for the best VPN bundle, and Sophos Home Premium for protecting multiple devices.

Intego Mac Internet Security

PCs were introduced before Apple’s Macintosh, leading to the emergence of PC viruses and the establishment of antivirus companies, with Macintosh protection being less prioritized. Intego focused on Macintosh security from the start, offering Intego Mac Internet Security, which includes a firewall that manages network permissions and defends against external attacks. Intego has been effective against Mac malware, achieving a 99.1% malware detection score in independent lab tests, although it lacks phishing protection, a feature offered by competitors Norton 360 Deluxe and Bitdefender Antivirus Plus. Intego's pricing is competitive, with a standard annual fee of .99 for a single license and .99 for three licenses. A five-device subscription costs .99, while the Mac Premium Bundle starts at .99 annually and includes additional features. A 14-day free trial is available, and free alternatives like Avast and AVG are also on the market. Intego supports older macOS versions back to Mavericks (10.9), but the latest version requires High Sierra (10.13) or later. The installation process for Intego is straightforward, requiring a restart and granting necessary permissions. The main interface includes components for updates, firewall, and antivirus, with user-friendly access to scanning options. Intego has received certification from AV-Comparatives and detected 100% of Windows malware samples in tests. Its quick scan takes about two and a half minutes, while a full system scan takes seven minutes. Intego's Safe Browsing feature checks existing browser protections but lacks a dedicated antiphishing solution. The NetBarrier firewall allows users to classify their network and manage traffic permissions effectively, although it may be complex for some users.
