Privacy Technologies for Secure Web Browsing

The browser is often the easiest entry point for cyber threats. Here's the best thing to help secure your browser. Remote Browser Isolation (RBI). WHY: RBI addresses vulnerabilities of traditional browser usage like: → Zero-hour phishing → Malware → Credential theft → Session hijacking → Browser extension vulnerabilities HOW: → RBI separates users’ browsing activities from your network → Sessions are contained in a secure, remote environment → Web content is converted to safe code before it reaches the user → Only sanitized content is displayed, blocking potential threats → All this happens through your existing browser How CISOs should IMPLEMENT RBI: → Do an as-is browser posture assessment → Do a pilot of RBI with key departments → Integrate RBI with proxies, firewalls, & security policies → Use browsing forensics to enhance your RBI strategy → Roll it out organization-wide once you're sure Are you securing your browser enough? If not, my team can guide you through a tailored approach with Menlo Security Inc. RBI solution. P.S. How many times have you sensed that things are wrong while browsing / downloading?

OSINTers often spend a lot of time investigating other people. However, we might forget to cover ourselves at the same time. Here’s a list of tools and resources to help you fix some of the OPSEC sins we can all be guilty of! • Operation Privacy, https://lnkd.in/gfjFZJY2 - An online dashboard providing free OPSEC advice and resources, helping users track their privacy to prevent stalkers, swatters, and doxxing. • Techlore Privacy and Security Resources, https://lnkd.in/ghtBW9HT - Provides a comprehensive series of guides to personal security and tools such as the VPN toolkit, for comparing the practices of different VPN providers. • Privacy Guides, https://lnkd.in/gy8D_Xba - Another comprehensive series of OPSEC resources, including the Knowledge Base, articles, recommendations, and a forum for tightening your personal security. • Privacy Virtual Cards, https://privacy.com/ - Leading provider of virtual payment cards in the US, limiting the amount of personal information is shared through purchases. • Digital Defence, https://lnkd.in/gS_4zJhh - Provides free personal security checklists for categories such as authentication, web browsing, email, etc. • DuckDuckGo, https://duckduckgo.com/ - A search engine protecting the privacy of its users by not storing personal user information, and or personalising results. • Mullvad, https://lnkd.in/gCxrS8Kh - A service offering a privacy-focused browser as well as a VPN in order to maximise the security of the user and minimise internet fingerprinting. • DNS Leak Test, https://lnkd.in/gicNFiNz - Identifies domain name system and web real-time communication leaks related to the user’s IP address. • VMware, https://www.vmware.com/ - A service allowing users to create virtual machines, allowing for compartmentalisation when working on sensitive projects. • Proxmox, https://lnkd.in/g3h6wecy - An open-source platform allowing users to create virtualised environments, secure email servers and add network-level VPN protections to enhance their online privacy. • JMPchat, https://jmp.chat/ - A service providing US and Canadian phone numbers for compartmentalization. • Firefox Relay, https://relay.firefox.com/ - Allows users to mask their email address and phone number, remove email trackers, block promotional emails, and add VPN protection from Mozilla. • addy.io, https://addy.io/ - Protects users’ email addresses by using email aliases, protects identities in data breaches, encrypts emails, and identifies where data may have been sold by using a different email address in every site. • SimpleLogin, https://lnkd.in/gEkaDecN - A browser extension and app providing anonymous email addresses and email aliases when signing up for an online service. These are just a few of the tools and resources you can use to stay safe on the internet and in your OSINT investigations. Stay alert and stay secure.

I've been asked a hundred times: what tools should I use for privacy? Here's what I learned from 20 years of experience and a federal case. No theory. Just what works and what doesn't. 🔹 Operating System: → Linux or Unix. Period. Nothing else. → Windows and MacOS send telemetry constantly. You are the product. → Encrypt everything with VeraCrypt (TrueCrypt successor). 🔹 Messengers (ranked): → Jabber/XMPP: declining ecosystem, but still solid if configured right → Tox: for the truly paranoid. No servers. P2P. → Telegram: convenient, but requires a phone number. Trade-off. 🔹 VPN + Tor: → VPN (rotate monthly) + Tor is sufficient for most threat models → The key word is "rotate." Never keep the same endpoint. 🔹 Passwords: → 30+ characters. Truly unique per service. → Store them on paper. In a physical notebook. In a safe. → Not a password manager app. Paper. 🔹 The Golden Rule: → Never meet in person anyone who knows you online. → Never. Not once. Not for any reason. → The Carder Conference taught me this. Photos = evidence = conviction. My laptop was encrypted with TrueCrypt. When I was arrested, the stress was so intense I genuinely forgot the password. They never cracked it. Sometimes forgetting is the best security feature. This isn't paranoia. It's the minimum viable privacy in 2024. #cybersecurity #privacy #opsec #encryption #infosec

Apple CPU Flaw May Let Hackers Steal Your Data: 8 Ways To Stay Safe Security researchers have uncovered vulnerabilities in modern Apple CPUs that could let hackers extract sensitive information directly from your web browser. These attacks, known as FLOP and SLAP, exploit Apple's speculative execution—a feature designed to speed up processing—causing the CPU to reveal confidential data before correcting itself. This means that just by opening the wrong website, your Gmail inbox, Amazon order history, Google Maps location, or even your iCloud calendar events could be exposed to cybercriminals. Even worse, these attacks can happen remotely without requiring any downloads, malware, or physical access to your device. 1. Consider Disabling JavaScript For Untrusted Websites The FLOP and SLAP attacks rely on JavaScript running in your web browser. Temporarily disabling JavaScript in Safari or Chrome can help mitigate the risk. However, be aware that many websites rely on JavaScript for functionality, so this might impact your browsing experience. In Safari: Open Settings > Safari > Advanced, then disable JavaScript. (Note: This may break some website functionality.) In Chrome: Use extensions like NoScript or uBlock Origin to selectively block JavaScript on untrusted sites 2. Keep Your Browser And Operating System Updated Make sure you: Regularly update macOS and iOS by enabling automatic updates. Keep Safari and Chrome updated to their latest versions, as browser vendors may introduce mitigations before Apple releases a CPU-level fix. 3. Use A Privacy-Focused Browser Browsers like Brave, DuckDuckGo, and Firefox focus on privacy and security, providing additional layers of protection against tracking and browser-based attacks. 4. Enable Strict Privacy And Security Settings Enhance your browser security by: Blocking third-party cookies. Using private browsing mode to limit data exposure. Enabling enhanced tracking protection (available in Firefox and Brave). Please see article for additional suggestions: https://lnkd.in/gx_AMHt4 #cybersecurity #Apple #FLOP #SLAP
