Just when you think cybercriminals have exhausted their bag of tricks, they come up with new and ingenious ways to scam people. Their latest tactic involves faking data breaches to deceive both unsuspecting business owners and buyers on the dark web.
Earlier this year, Europcar, a global car rental company based in France, discovered a cybercriminal attempting to sell private information about its more than 50 million customers on the dark web. Upon launching a formal investigation, Europcar found that the data being sold was fraudulent, likely generated using advanced AI technologies.
How Do They Pull It Off?
With AI-powered tools like ChatGPT, cybercriminals can quickly create realistic-looking data sets. These savvy criminals conduct thorough research to design data sets that appear legitimate, complete with correctly formatted names, addresses, emails, and even local phone numbers. They also use online data generators intended for software testing to produce large, authentic-looking data sets. Once armed with this fake data, hackers choose a target company and post the fabricated information on the dark web.
Why Are They Doing This?
Why would hackers fake a data breach? There are several reasons, beyond the obvious benefit of avoiding the effort required to breach a network's security system:
- Creating Distractions: One effective way to lower a company's defenses is to divert attention elsewhere, such as by making them search for a non-existent breach. The company becomes so focused on this phantom threat that it may overlook actual vulnerabilities.
- Bolstering Their Reputation: In the hacker community, reputation is crucial. Publicly targeting a well-known brand can earn hackers notoriety and recognition from other groups.
- Manipulating Stock Prices: For publicly traded companies, news of a data breach can cause a rapid 3% to 5% (or more) drop in stock value. This panic can be exploited by cybercriminals for financial gain.
- Learning Security Systems: Faking a data breach allows cybercriminals to glean insights into a company's security protocols for preventing, detecting, and resolving attacks. Understanding response times and security capabilities helps them refine their strategies for future attacks.
Why Is This Harmful to Businesses Even If the Data Is Fake?
By the time it's revealed that the data is fake, significant damage may already have been done. For instance, in September 2023, Sony was targeted by a ransomware group that falsely claimed to have breached the company's network and acquired its data. The news spread rapidly, tarnishing Sony's reputation, and by the time the investigation confirmed the breach was a hoax, the damage to Sony's brand was irreparable.
How Can You Prevent Fake Data Breaches?
To avoid falling victim to a fake data breach, consider these steps:
- Actively Monitor the Dark Web: Regularly monitor the dark web, either personally or through your cybersecurity team. If you find someone selling your data, investigate the claim immediately to mitigate potential damage.
- Have a Disaster Recovery Plan in Place: Develop and fine-tune a communication plan in advance, so your team knows exactly what to say and do if a data breach occurs.
- Work with a Qualified Professional: Focus on your business while leaving IT-related issues to cybersecurity experts. These professionals can identify threats, resolve issues, and prevent breaches, ensuring that steps #1 and #2 are effectively managed.
