Meta's latest approach to sabotage Facebook data is revealed

Meta's latest approach to sabotage Facebook data is revealed ...

Since the Cambridge Analytica scandal of 2018, large tech firms have had a lot of trouble posing this challenge. One such way is by using unauthorized information scraping, where scripts and tools are used to collect information from a website. Meta has now explained its latest strategy to address this problem.

It''s important to keep in mind that data destruction isn''t inherently illegal. In fact, public data can be scraped through authorized means, but Meta isn''t interested in utilizing automated algorithms for this process. One technique used by unauthorized parties is to destroy data by imagining the Facebook ID (FBID) in a URL.

The URLs have an FBID that allows unauthorized scrapers to equate them or purchase them from other malicious actors. Content from the URL is then cross-referenced with other data points to create rich profiles and datasets which are then sold.

Meta has now replaced FBIDs with Pseudonymized Facebook Identifiers (PFBIDs) which are significantly more secure and difficult to detect due to the fact that they are produced based on timestamps, which are also rotated.

This helps deter unwanted data scraping by making it easier for attackers to guess, connect, and repeatedly access data.

These identifiers are not designed to prevent browser tools from eliminating tracking components from the URL. This process is designed to improve people''s privacy by reducing enumeration and time-delayed attacks, while also preserving the ability to have long-lived links.

The aim of the initiative is to deter attackers from regaining access to user data by guessing an identification. That''s why Meta hasn''t revealed if this change in the technical implementation of URLs has resulted in any significant benefit.
