🌐 Millions of Internet Hosts at Risk Due to Tunneling Protocol Vulnerabilities 🌐   Recent research by KU Leuven’s Prof. Mathy Vanhoef and PhD student Angelos Beitis, in collaboration with Top10VPN, has uncovered alarming vulnerabilities in tunneling protocols used by over 4 million internet systems, including VPN servers and home routers.   👉 The Issue: Tunneling protocols like IPIP/IP6IP6, GRE/GRE6, 4in6, and 6in4, designed to transport data between networks, were found vulnerable due to misconfigurations. These flaws allow unauthenticated packets from malicious actors to exploit vulnerable hosts, enabling attacks like: > DoS attacks > DNS spoofing > Gaining access to internal networks and IoT devices Of the 4.26 million exposed systems, 1.8 million are spoofing-capable, making it nearly impossible to trace attackers. These compromised hosts can serve as one-way proxies, amplifying the impact of anonymous attacks.   👉 Implications for Small Businesses: Many of the affected systems include VPN servers, routers provided by ISPs, and mobile network gateways—technologies often utilized by micro and small businesses. A breach could result in compromised internal systems, loss of sensitive data, and business disruptions.   👉 Our Recommendation: Proactively secure your network by: > Auditing tunneling protocol configurations. > Limiting traffic to trusted sources. > Updating firmware for routers and VPN servers. > Partnering with a cybersecurity solutions provider to identify and mitigate vulnerabilities. 📍The highest concentration of vulnerable hosts was found in China and France, but this serves as a global reminder of the critical need for robust cybersecurity measures.   If your business relies on tunneling protocols, act now to safeguard your infrastructure. 💻🔒   Learn more, visit: https://lnkd.in/gHdXNhvr   #CompCiti #Cybersecurity #CyberAware #DataProtection #SmallBusinessSolutions #NetworkSecurity #TunnelingProtocols

Corporate Cyber Governance: Embracing Cyber Risk at the Board Level   Cybersecurity is no longer just an IT issue—it is a strategic enterprise risk that demands ownership and active oversight by company boards and leadership. In today’s interconnected and increasingly volatile landscape, where cyber threats from nation-state adversaries are growing, boards play a pivotal role in national security and systemic resilience.   To guide boards in effectively managing cyber risk, the NACD Director’s Handbook on Cyber-Risk Oversight provides a comprehensive framework for governance. Here are key takeaways for board members and executives to foster a culture of cybersecurity: 1. Empower CISOs and Prioritize Cybersecurity Ensure Chief Information Security Officers (CISOs) have the resources, authority, and visibility to prioritize cybersecurity effectively. Decisions that compromise security for cost or speed must be made transparently at the executive and board level. 2. Educate and Engage on Cyber Risk Board members and senior executives must be well-informed on cybersecurity risks and ensure these risks are central to business, technology, and acquisition decisions. Cyber risk oversight should be delegated to a dedicated cybersecurity or technology risk committee for focused management. 3. Adopt a Standardized Risk Framework Develop and implement standardized methods to measure and monitor cyber risk exposure, and ensure timely reporting of both successful breaches and “near misses” to improve defenses. 4. Champion Collaborative Cybersecurity Promote proactive information sharing about cyber threats with government and industry peers. A collaborative approach strengthens collective resilience against malicious activity. As cybersecurity becomes a cornerstone of good governance, it is imperative for CEOs and boards to treat cyber risk with the same urgency as financial risk. Embracing this responsibility not only protects organizations but also strengthens the broader ecosystem. At the board level, cyber literacy is as essential as financial literacy—an investment in understanding that pays dividends in resilience.   Learn more, visit: https://lnkd.in/gZk5ieCb   #CompCiti #Cybersecurity #CyberAware #CyberGovernance #CyberRisk #Leadership

Avoid Phishing Scams with Three Simple Tips:   Phishing scams are online messages designed to look like they’re from a trusted source. We may open what we thought was a safe email, attachment or image only to find ourselves exposed to malware or a scammer looking for our personal data. The good news is we can take precautions to protect our important data. Learn to recognize the signs and report phishing to protect devices and data.   1) Recognize the common signs    • Urgent or emotionally appealing language  • Requests to send personal or financial information  • Unexpected attachments  • Untrusted shortened URLs  • Email addresses that do not match the supposed sender  • Poor writing/misspellings (less common)   2) Resist and report:   Report suspicious messages by using the “report spam” feature. If the message is designed to resemble an organization you trust, report the message by alerting the organization using their contact information found on their webpage.   3) Delete:   Delete the message. Don’t reply or click on any attachment or link, including any “unsubscribe” link. The unsubscribe button could also carry a link used for phishing. Just delete.   If a message looks suspicious, it’s probably phishing. But even if there’s a possibility it could be real, don’t click any link, attachment or call any number. Look up another way to contact a company or person directly:    👉 Go to a company’s website to find their contact information  👉 Call the individual at a known number and confirm whether they sent the message   Taking these steps helps Secure Our World.

Our online world needs to be protected. There are easy things we can do to ensure our information is safe from those wishing to steal it.   Use Strong Passwords: Simple passwords can be guessed. Make passwords at least 16 characters long, random and unique for each account. Use a password manager, a secure program that maintains and creates passwords. This easy-to-use program will store passwords and fill them in automatically on the web.   Turn on Multifactor Authentication (MFA): Use MFA on any site that offers it. MFA provides an extra layer of security in addition to a password when logging into accounts and apps, like a face scan or a code sent by text. Using MFA will make you much less likely to get hacked.   Update Software: When devices, apps or software programs (especially antivirus software) notify us that updates are available, we should install them as soon as possible. Updates close security code bugs to better protect our data. Turn on automatic updates to make it even easier.   Recognize & Report Phishing: Most successful online intrusions result from a recipient of a “phishing” message accidentally downloading malware or giving their personal information to a spammer. Do not click or engage with these phishing attempts. Instead, recognize them by their use of alarming language or offers that are too good to be true. Report the phish and delete phishing messages.   Taking these steps helps Secure Our World.
