Just when you think cybercriminals have exhausted their bag of tricks, they innovate and catch you off guard. The latest tactic involves fabricating data breaches to swindle money from unsuspecting business owners and dark web data buyers alike.
Earlier this year, Europcar, a global car rental company based in France, discovered a cybercriminal selling purportedly private information about its 50 million+ customers on the dark web. Upon launching a formal investigation, the company found that the data being sold was fake, likely generated using advanced AI tools.
How Do They Do It?
With AI-powered tools like ChatGPT, cybercriminals can swiftly generate realistic-looking data sets. These savvy criminals conduct thorough research to create data sets that appear legitimate, complete with correctly formatted names, addresses, emails, and even local phone numbers. They also use online data generators designed for software testing to produce large, authentic-looking data sets. Once equipped with these fabricated data sets, hackers target a specific company and post the counterfeit information on the dark web, claiming it was stolen.
Why Are They Doing It?
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: Diverting a company's attention to a supposed breach can cause it to lower its defenses elsewhere, making it vulnerable to other attacks.
- Bolstering Their Reputation: Within the hacker community, reputation is paramount. Publicly targeting a well-known brand can earn hackers notoriety and recognition from other groups.
- Manipulating Stock Prices: For publicly traded companies, a data breach can result in a rapid 3% to 5% (or more) drop in stock prices. This panic can be exploited by cybercriminals for financial gain.
- Learning Security Systems: Faking a data breach can provide cybercriminals with insights into a company's security measures, helping them refine their attack strategies.
Why Is This Bad For Businesses If The Data Is Fake?
Even if the data is fake, the damage can be significant by the time the public learns the truth. For instance, in September 2023, Sony was targeted by a ransomware group that claimed to have breached its network and acquired its data. The news spread rapidly, tarnishing Sony's reputation. By the time the investigation revealed the hacker's claim was false, the damage to Sony's brand was already done.
What Can You Do To 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 for any signs of your data being sold. If you find an attacker selling your data, investigate immediately to mitigate potential damage.
- Have A Disaster Recovery Plan In Place: Develop a communication plan in advance so your team knows how to respond if a data breach occurs. This plan should be refined and ready to implement when needed.
- Work With A Qualified Professional: Focus on your core business activities and leave IT-related issues to cybersecurity experts. A qualified professional can handle monitoring, issue resolution, and breach prevention, ensuring that steps #1 and #2 are effectively managed.
