A recent leak made the personal information of 200,000 Facebook Marketplace users public. This is a scary development that shows how weak digital privacy is still. This incident, characterized by the unauthorized disclosure of mobile phone numbers, email addresses, and additional sensitive information, has sent shockwaves through the online community, raising serious questions about the security measures in place to protect user data on major platforms.
Facebook Marketplace: Understanding the Breach
The leak was first brought to light by a threat actor known as IntelBroker on a prominent hacker forum, where it was claimed that a vast array of personally identifiable information (PII) was compromised. This assertion was subsequently verified by BleepingComputer, which confirmed the authenticity of the leaked data through the matching of email addresses and phone numbers from the sample provided which are said to be from Facebook Marketplace.
At the heart of this breach is a cybercriminal operating under the alias ‘allocation’ on Discord. According to IntelBroker, this individual successfully infiltrated the systems of a Meta contractor in October 2023, absconding with a partial user database that contained a wide range of PII.
The compromised data includes names, phone numbers, email addresses, Facebook IDs, and profile details of Facebook Marketplace users.
Facebook Marketplace: The Potential Fallout
The implications of a leak of this magnitude are extremely extensive. Email addresses that are disclosed could be used as bait for phishing attacks, and mobile phone numbers could be used to aid mobile phishing or even SIM swap assaults.
Using these strategies can result in the interception of multi-factor authentication codes that are delivered over SMS, which gives attackers the ability to hijack user accounts with a relatively low level of difficulty.
IntelBroker, the organization that is responsible for this discovery, is not unfamiliar with issues involving cybersecurity. The breach of DC Health Link, which led to a congressional hearing, and the illicit selling of data from companies like Hewlett Packard Enterprise and General Electric Aviation are two examples of previous exploits that have been connected to this threat actor.
A Recurring Challenge for Meta
For Meta, the parent company of Facebook, this incident is a stark reminder of the challenges it faces in safeguarding user data. The company previously encountered significant scrutiny in November 2022 when it was fined €265 million for its inability to protect user information from scrapers.
This penalty was a consequence of a prior incident where data linked to over 533 million Facebook accounts was leaked, including mobile numbers, Facebook IDs, names, and additional personal details.
This pattern of data breaches and leaks underscores a troubling trend in digital security, highlighting the imperative for robust protective measures and transparent communication with users about the risks and safeguards related to their personal information.

Facebook Marketplace: Navigating the Digital Privacy Landscape
The Facebook Marketplace data leak is a sobering reminder of the fragility of digital privacy in today’s interconnected world. As users, it’s crucial to remain vigilant, practice secure online habits, and stay informed about potential threats to personal data. For platforms like Facebook, this incident serves as a call to action to fortify their defenses, ensure the integrity of third-party contractors, and rebuild user trust through transparency and accountability.
In the wake of this breach, the digital community must engage in a concerted effort to enhance data protection standards and ensure that individuals’ privacy is not compromised in the vast expanse of the internet.
