The Rise of Supercookies: Unveiling the Dark Side of Online Surveillance

S3 Ep143: Supercookie surveillance shenanigans

Introduction

In the latest episode of the Naked Security podcast, hosts Doug Aamoth and Paul Ducklin discuss various topics related to internet security and privacy. They first reminisce about slide rules and the end of the mathematical era. Then, they delve into the controversy surrounding the discontinuation of support for Windows 7 and the importance of keeping operating systems up to date. They also highlight Microsoft’s recent patching of zero-day vulnerabilities and the significance of Elevation of Privilege (EoP) attacks. In addition, they explore the concept of “Rowhammer” attacks and the potential for supercookies to track users’ online activities. Finally, they examine a bug in the Ghostscript project and the mishap with Apple’s emergency patch for a zero-day vulnerability.

Internet Security and Privacy Concerns

The podcast episode raises several important issues related to internet security and privacy. The discontinuation of support for Windows 7 serves as a reminder of the importance of keeping operating systems updated to protect against vulnerabilities and potential exploits. While it may be inconvenient for some users to switch to newer versions of operating systems, it is crucial for their own safety and the security of others. As Paul Ducklin points out, using outdated operating systems with unpatched bugs puts users at risk of being exploited by cybercriminals.

The discussion also brings attention to the importance of patching zero-day vulnerabilities, as highlighted by Microsoft’s recent efforts. Zero-day vulnerabilities pose a significant threat because they are unknown to the software vendor and can be exploited by attackers before a patch is developed. By actively patching such vulnerabilities, Microsoft demonstrates its commitment to addressing security issues promptly and protecting its users.

The Dangers of Supercookies

The conversation then turns to the concept of supercookies and their implications for online privacy. Supercookies are persistent tracking mechanisms that can identify users across different websites and devices. Unlike regular cookies, which users can delete or control, supercookies are nearly impossible to remove and can continue to track users’ online activities even after they have cleared their browser data.

The ability of supercookies to track users raises concerns about online surveillance and the potential misuse of personal data. Websites and advertisers can gather extensive information about users’ browsing habits, preferences, and personal details, leading to targeted advertising and potential privacy breaches. As Doug Aamoth mentions, websites should reconsider their reliance on User-Agent strings to track users and adopt more privacy-conscious practices.

Editorial and Advice

In light of the discussions and concerns raised in the podcast, it is crucial for individuals and organizations to prioritize internet security and privacy. Here are some recommendations:

1. Keep operating systems and software up to date: Regularly install patches and updates to ensure that your devices are protected against known vulnerabilities. This includes not only the operating system but also applications and plugins.

2. Be cautious of outdated software: Using unsupported software, such as Windows 7, increases the risk of exploitation by cybercriminals. Consider upgrading to the latest supported versions or alternative software if necessary.

3. Practice good password hygiene: Use strong, unique passwords for all your online accounts and enable multi-factor authentication whenever possible. Regularly change passwords and avoid using the same password across multiple accounts.

4. Utilize security tools: Install reputable antivirus software and keep it updated to detect and prevent malware infections. Use a virtual private network (VPN) to encrypt your internet traffic and protect your privacy when browsing.

5. Be mindful of online tracking: Regularly review and adjust your privacy settings in web browsers and applications to limit the collection and tracking of your personal information. Consider using browser extensions or plugins that block trackers and ads.

6. Educate yourself and others: Stay informed about current internet security and privacy issues. Raise awareness among friends, family, and colleagues about the importance of cybersecurity practices and maintaining personal privacy online.

In conclusion, the Naked Security podcast episode highlights the ongoing challenges and risks associated with internet security and privacy. By staying informed, adopting best practices, and prioritizing security, individuals can better protect themselves and their data in the digital age.
