Just when it seems like cybercriminals have exhausted their bag of tricks, they manage to innovate and catch us off guard. Their latest scheme involves fabricating data breaches to deceive both unsuspecting business owners and buyers on the dark web.
Earlier this year, Europcar, a global car rental service based in France, stumbled upon a cybercriminal attempting to sell the personal data of over 50 million customers on the dark web. Upon investigation, Europcar discovered that the data was counterfeit, likely created with the assistance of generative AI.
How Do They Achieve This?
Using AI-driven tools like ChatGPT, cybercriminals can swiftly produce realistic-looking datasets. These criminals conduct thorough research to craft datasets that appear complete, with properly formatted names, addresses, and emails, even incorporating local phone numbers. They also utilize online data generators designed for software testing to create large, convincing fake datasets. Once prepared, these hackers select a target company to falsely attribute the data to and then post the information on the dark web.
Why Are They Engaging in This?
Faking a data breach offers several advantages without the effort of breaching a network's security.
- Creating Distractions: By diverting a company's attention to a supposed breach, they may lower their defenses elsewhere, making them vulnerable to attacks from other angles.
- Enhancing Reputation: Within the hacker community, reputation is crucial. Publicly targeting a well-known brand can elevate a hacker's status and attract attention from other groups.
- Manipulating Stock Prices: For publicly traded companies, news of a data breach can lead to a swift 3% to 5% drop in stock prices, creating opportunities for cybercriminals to exploit the market for profit.
- Gaining Security Insights: By faking a breach, cybercriminals can learn about a company's security protocols, including their response times and capabilities, allowing them to refine future attack strategies.
Why Are Fake Data Breaches Harmful to Businesses?
Even if the data is fake, the damage is often done before the truth is revealed. For instance, in September 2023, Sony was targeted by a ransomware group claiming to have breached their network. The news spread rapidly, tarnishing Sony's reputation, and by the time it was proven false, the damage to their image was irreversible.
How Can You Guard Against Fake Data Breaches?
To protect yourself from fake data breaches, consider these steps:
- Monitor the Dark Web Regularly: Ensure that you or your cybersecurity team routinely check the dark web. If you find someone selling your data, investigate immediately to mitigate potential damage.
- Develop a Disaster Recovery Plan: Have a communication strategy ready in advance to address potential data breaches, refining it as needed.
- Collaborate with a Cybersecurity Expert: Focus on your core business by partnering with a cybersecurity professional. They can handle IT issues, resolve and prevent breaches, and ensure the above steps are effectively managed, providing you with peace of mind.
