How Scammers Are Exploiting Your Website Cookies: Internet Scambusters #1,139
Have you ever wondered how websites remember your login details or why that ad for running shoes follows you across the internet? The answer lies in those tiny data packets called cookies.
In this week’s issue, Scambusters will describe how scammers use website cookies to steal your personal information.
Let's get started…
Hidden Dangers in Your Website Cookies
Website cookies are small pieces of data stored on your device by the websites you visit. These data pieces contain information about your browsing activity and preferences, making it easier for websites to enhance user experience by remembering login details and settings.
Cookies are created when your browser loads a website and is sent back to the server whenever you revisit a site. While they can be incredibly useful, they also have a dark side that is often overlooked.
Types of Website Cookies
Not all cookies are created equal. There are several types of website cookies, each serving different functions:
- Session Cookies: These temporary cookies expire once you close your browser. They help websites keep track of your actions during a single browsing session.
- Persistent Cookies: Unlike session cookies, persistent cookies remain on your device even after you close your browser. They help websites remember your preferences and login details for future visits.
- Third-Party Cookies: These cookies are set by domains other than the one you're visiting. They are often used for tracking and advertising purposes, collecting data across various sites.
- Secure Cookies: These cookies are only transmitted over secure, encrypted connections, making them safer but not immune to all threats.
The primary purpose of website cookies is to enhance user experience and improve website functionality. Some key functions include:
- Personalization: Cookies customize your browsing experience by remembering preferences like language settings and themes.
- Login Management: They store login credentials, allowing you to stay signed in and avoid entering passwords repeatedly.
- Analytics: Cookies help website owners understand user behavior through metrics like page views and time spent.
- Targeted Advertising: Marketers use cookies to deliver personalized ads based on browsing history and interests.
While all this information is interesting and the functions are beneficial, they also make cookies a prime target for scammers looking to exploit user information.
Threats of Website Cookies
Despite their benefits, cookies pose several security risks. Here are some of the threats:
- Data Breaches: If malicious actors access the server storing cookie data, they can steal sensitive information, including login credentials and personal details.
- Tracking: Third-party cookies can track your browsing activities across multiple sites, creating detailed profiles that infringe on your privacy.
- Cookie Stealing: Techniques like cross-site scripting (XSS) can allow hackers to steal your cookies and gain unauthorized access to your accounts.
- Misuse: Even legitimate companies can misuse cookies to collect more data than necessary, selling it to third parties without your consent.
Third-Party Cookies
Third-party cookies have long been a hot topic in digital marketing and web browsing. But what are the hidden dangers they pose? More importantly, how do these cookies impact users' personal information?
These cookies are usually embedded in ads, social media buttons, or third-party services. When you interact with these elements, the cookie is placed in your browser, allowing third-party entities to monitor your online activities.
Marketers and advertisers use third-party cookies to create detailed user profiles. These profiles help serve targeted ads and measure the effectiveness of marketing campaigns.
The collected data can include your IP address, browsing history, search queries, and email metadata. Over time, this information can be used to build an accurate profile. The extent to which third-party cookies collect data raises significant privacy concerns. Users often have no control over who accesses their data and how it’s used, leading to potential misuse.
Because third-party cookies often involve multiple parties sharing data, the risk of data breaches increases. If one of these parties fails to secure their data, your personal information could be exposed.
Third-party cookies often lead to unintended data sharing. The companies that collect your data may sell or share it with other entities without your explicit consent, including the dark web.
While not all data collected by third-party cookies ends up on the dark web, it’s a significant risk. Stolen or leaked data can be sold to malicious actors who use it for fraudulent activities.
The dark web has a thriving market for stolen data. Information ranging from email addresses to more sensitive data like Social Security numbers can be bought and sold, making third-party cookies a potential conduit for this illegal trade.
Clearing Cookies
Clearing cookies from your computer is straightforward and can enhance your privacy:
- Browser Settings: Navigate to your browser's settings or preferences menu, find the privacy or security section, and select the option to clear cookies.
- Extensions: Use browser extensions like Cookie AutoDelete to automatically remove cookies after each session.
- Regular Maintenance: Clear your cookies periodically, especially if you notice targeted ads or feel your privacy is compromised.
By regularly clearing cookies, you can maintain better control over your online privacy.
How Do Scammers Get Access To Website Cookies?
Scammers employ various techniques to access your cookies and exploit them for malicious purposes:
- Phishing: Scammers send fake emails or messages that trick you into visiting malicious websites that steal your cookies.
- Malware: Malicious software installed on your device can harvest your cookies and send them to scammers.
- Man-in-the-Middle Attacks: Scammers intercept data transmitted between your device and a website, capturing your cookies.
- Cross-Site Scripting (XSS): Hackers inject malicious scripts into legitimate websites, stealing your cookies when you visit these sites.
Can Website Cookies Be Avoided?
While it’s almost impossible to avoid cookies altogether, you can take steps to minimize their impact:
- Browser Settings: Most browsers allow you to block third-party cookies, delete cookies after each session, and manage cookie permissions.
- Private Browsing: Using incognito or private browsing modes can prevent cookies from being stored on your device.
- Extensions: Privacy-focused browser extensions can block unwanted cookies and trackers.
- Cookie Consent: Always read cookie consent banners carefully and opt out of nonessential cookies whenever possible.
To mitigate the risks of website cookies, read the cookie consent and know what you agree to. Several browser extensions can block third-party cookies, making it hard for companies to track you. Try googling your options to learn more.
Most modern browsers offer settings that allow you to block or limit third-party cookies. By adjusting these settings, you can significantly reduce the amount of data collected about you.
Do I Have to Accept Cookies to Get to a Website?
In most cases, you can still access a website without accepting all cookies, although your experience might be limited:
- Essential Cookies: Some cookies are necessary for basic website functionality. Refusing these might prevent you from using certain features, like logging in or completing purchases.
- Non-Essential Cookies: These include analytics, personalization, and advertising cookies. You can usually decline them without significantly impacting your browsing experience.
Always carefully read cookie consent banners and choose the option that best aligns with your privacy preferences. Do not assume it is okay to accept all cookies.
Conclusion
Website cookies are a double-edged sword; they enhance user experience and pose significant privacy risks. By understanding what cookies are, the different types, their purposes, and the threats they pose, you can take steps to protect your privacy.
