Online Trackers Increasingly Switching to Invasive CNAME Cloaking Technique

Online Trackers Increasingly Switching to Invasive CNAME Cloaking Technique
Feb 24, 2021
With browser makers steadily clamping down on third-party tracking, advertising technology companies are increasingly embracing a DNS technique to evade such defenses, thereby posing a threat to web security and privacy. Called  CNAME Cloaking , the practice of blurring the distinction between first-party and third-party cookies not only results in leaking sensitive private information without users' knowledge and consent but also "increases [the] web security threat surface," said a group of researchers Yana Dimova, Gunes Acar, Lukasz Olejnik, Wouter Joosen, and Tom Van Goethem in a new study. "This tracking scheme takes advantage of a CNAME record on a subdomain such that it is same-site to the including web site," the researchers  said  in the paper. "As such, defenses that block third-party cookies are rendered ineffective." The findings are expected to be presented in July at the 21st Privacy Enhancing Technologies Symposium (PETS 2021). Rise

Over 400 Popular Sites Record Your Every Keystroke and Mouse Movement

Over 400 Popular Sites Record Your Every Keystroke and Mouse Movement
Nov 22, 2017
How many times it has happened to you when you look for something online and the next moment you find its advertisement on almost every other web page or social media site you visit? Web-tracking is not new. Most of the websites log its users' online activities, but a recent study from Princeton University has suggested that hundreds of sites record your every move online, including your searches, scrolling behavior, keystrokes and every movement. Researchers from Princeton University's Centre for Information Technology Policy (CITP) analyzed the Alexa top 50,000 websites in the world and found that 482 sites, many of which are high profile, are using a new web-tracking technique to track every move of their users. Dubbed " Session Replay ," the technique is used even by most popular websites, including The Guardian, Reuters, Samsung, Al-Jazeera, VK, Adobe, Microsoft, and WordPress, to record every single movement a visitor does while navigating a web page,

How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl
Mar 21, 2024SaaS Security / Endpoint Security
In today's digital-first business environment dominated by SaaS applications, organizations increasingly depend on third-party vendors for essential cloud services and software solutions. As more vendors and services are added to the mix, the complexity and potential vulnerabilities within the  SaaS supply chain  snowball quickly. That's why effective vendor risk management (VRM) is a critical strategy in identifying, assessing, and mitigating risks to protect organizational assets and data integrity. Meanwhile, common approaches to vendor risk assessments are too slow and static for the modern world of SaaS. Most organizations have simply adapted their legacy evaluation techniques for on-premise software to apply to SaaS providers. This not only creates massive bottlenecks, but also causes organizations to inadvertently accept far too much risk. To effectively adapt to the realities of modern work, two major aspects need to change: the timeline of initial assessment must shorte

Websites Can Now Track You Online Across Multiple Web Browsers

Websites Can Now Track You Online Across Multiple Web Browsers
Feb 15, 2017
You might be aware of websites, banks, retailers, and advertisers tracking your online activities using different Web "fingerprinting" techniques even in incognito/private mode, but now sites can track you anywhere online — even if you switch browsers. A team of researchers has recently developed a cross-browser fingerprinting technique — the first reliable technique to accurately track users across multiple browsers based on information like extensions, plugins, time zone and whether or not an ad blocker is installed. Previous fingerprinting methods usually only work across a single browser, but the new method uses operating system and hardware level features and works across multiple browsers. This new fingerprinting technique ties digital fingerprint left behind by a Firefox browser to the fingerprint from a Chrome browser or Windows Edge running on the same device. This makes the method particularly useful to advertisers, enabling them to continue serving tar
