Privacy-Enhanced Browsing: A Necessity in Today's Digital Landscape

"Privacy on the internet is a myth."

This statement holds more truth today than ever as our digital lives increasingly intertwined with our offline existence. As a result, online privacy has evolved into a critical issue, with countless individuals and organizations falling victim to data breaches, tracking cookies, and various forms of surveillance. To counter these threats, privacy-enhanced browsing has become crucial in safeguarding our online presence and personal information.

The extent of data breaches and hacks through browsers is alarming. One notable example occurred in 2013 when Yahoo.com reported that 3 billion accounts had been compromised —a staggering revelation that only came to light in 2016. This incident highlights the potential vulnerability of our personal information, even when stored with well-established service providers.

Moreover, relying on SSL-certified websites and contemporary web browsers is not foolproof. For instance, a recent study by IT security researchers from Ruhr-Universit?t Bochum (RUB) and Niederrhein University of Applied Sciences unveiled 14 new types of 'XS-Leak ' cross-site leak attacks against popular web browsers, including Google Chrome, Microsoft Edge, Safari, and Mozilla Firefox.

Understanding XS-Leak Attacks and Their Implications

XS-Leak attacks are side-channel attacks that bypass a web browser's same-origin policy. This policy is intended to prevent a malicious website from accessing sensitive data from another site a user has visited. However, with XS-Leak attacks, the same-origin policy can be undermined, allowing attackers to steal information from a trusted site while the user is actively engaged.

For example, an XS-Leak attack could enable a malicious background site to access the contents of an active tab used to check webmail, potentially exposing private messages, personal information, or login credentials. These attacks emphasize the need for robust privacy-enhanced browsing solutions to protect users from cyber threats.

And that's just scratching the surface when it comes to threats online.

Adopting Privacy-Enhanced Browsing Techniques for Greater Online Security ( A checklist)

As we navigate the digital landscape, we must adopt privacy-enhanced browsing methods to safeguard our personal information and online activities. These techniques can include:

1. Utilizing privacy-focused browsers like Tor, Brave, or Firefox with enhanced privacy settings.
2. Implementing browser extensions that block tracking cookies, third-party scripts, and other privacy-compromising elements.
3. Regularly clearing browser cache, cookies, and browsing history to limit the amount of stored data that hackers can access.
4. Employing virtual private networks (VPNs) to encrypt internet connections and hide browsing activities from prying eyes.
5. Staying vigilant and avoiding suspicious websites, links, or downloads that could compromise privacy or security.

Assessing the Current State of Online Privacy

Online privacy is becoming an increasingly important concern in today's digital age. Understanding online privacy threats is crucial in developing effective strategies to protect our personal information.

1. Data breaches: Data breaches occur when sensitive information from websites, apps, or databases is stolen or leaked. Personal information, such as names, addresses, email addresses, and credit card numbers, can be exposed and misused by hackers for identity theft, fraud, or other malicious purposes. One notable example is the Microsoft Exchange data breach in January 2021 , which affected 30,000 businesses in the USA.
2. Tracking cookies: Tracking cookies are employed by many websites to monitor users' online activity and gather information about their browsing habits. This data may include search history, location, and shopping preferences. While advertisers utilize this information to target users with personalized ads, it also raises privacy concerns and the potential misuse of personal data. As a result, Google, on June 2021, sought to phase out third-party cookies , which is a significant blow to the online advertisement business because Google accounts for 68% of total web traffic.?
3. Social media platforms, such as Facebook and Twitter, collect massive amounts of user data, such as personal information, preferences, and online behavior. This data can be used to create detailed user profiles that can be used for targeted advertising or other purposes. Social media platforms have also been chastised for how they handle user data and for privacy violations. For example, recently, Bytedance, the parent company behind Tiktok came under scrutiny from the US government and FBI for sharing user data like location, biometrics, and browsing history with the Chinese government.??

4. Government monitoring: Governments all over the world are increasingly using online monitoring to monitor citizens' activities and communications. Emails, phone calls, and internet usage can all be monitored. Some governments have also enacted legislation requiring businesses to store user data or provide access to it upon request.?

It is not very uncommon for federal agencies to track user data to monitor illegal activities, including drug trafficking, money laundering, abuse on the internet, and terrorism. However, sometimes it is used to serve ulterior motives like spying on journalists, monitoring voters, etc. Government monitoring can lead to a “chilling effect” where people are likely to censor their voice on the internet in order to protect themselves from unwanted scrutiny.?

Similarly, some tools employ artificial intelligence to detect criminal behavior before it occurs. This is the case, for example, in Canada. According to a recent contract with Babel Street , the tool enables mass online surveillance by tracking, analyzing, and translating online communications.

Babel Street also received a million-dollar contract from the FBI . This contract, worth up to $27 million, began late last month (March 30) and will search through publicly available information, according to the FBI. While the information returned may be public, privacy advocates are concerned about the mass surveillance enabled by this technology and the lack of oversight over how the FBI uses it. The FBI's guidelines, for example, allow for the technology to be used in 'assessments,' i.e. before someone has technically committed a crime.

5. Phishing and malware: Phishing attacks and malware can be used to obtain sensitive information such as passwords or financial information. These attacks can take the form of emails, pop-up advertisements, or malicious software. These types of attacks have grown in sophistication, making them more dangerous and common. SlashNext, a messaging security provider, discovered in a recent report that more than 255 million attacks after analyzing billions of link-based URLs, attachments, and natural language messages in email, mobile, and browser channels over a six-month period in October 2022. The rate of phishing attacks has increased by 61% since 2021.

According to the study, cybercriminals are shifting their attacks to mobile and personal communication channels in order to reach users. It revealed a 50% increase in mobile device attacks, with scams and credential theft topping the list of payloads.
