Just when you think cybercriminals have exhausted their bag of tricks, they manage to innovate and catch everyone off guard. Now, they're fabricating data breaches, aiming to swindle money from both unsuspecting business owners and dark web data buyers.
Earlier this year, Europcar, a global car rental firm based in France, discovered a cybercriminal selling purported private information of its over 50 million customers on the dark web. The company promptly launched a formal investigation, only to find out that the data being sold was fake. The information was likely fabricated with the help of generative AI.
How Did They Do It?
Using 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 complete, with accurately formatted names, addresses, emails, and even local phone numbers. They also utilize online data generators designed for software testing to develop large, authentic-looking data sets. Once these data sets are ready, hackers select a target from which they claim to have stolen the data and post this information on the dark web.
Why Are They Doing It?
Why would hackers fake a data breach? There are several reasons, beyond reaping the same benefits without the hassle of breaching a network's security system.
- Creating Distractions: One effective way to make a company lower its defenses is to divert its attention elsewhere, such as searching for a breach in its system. The company becomes so focused on finding the supposed entry point that it may overlook an attack from another direction.
- Bolstering Their Reputation: Reputation is crucial in the hacker community. Publicly targeting a well-known brand can earn hackers notoriety and recognition from other hacker groups.
- Manipulating Stock Prices: For publicly traded companies, a data breach can cause a rapid 3% to 5% (or more) drop in stock prices. This can induce panic, allowing cybercriminals to manipulate stocks for financial gain.
- Learning Security Systems: Faking a data breach can give cybercriminals insights into a company's security processes for preventing, detecting, and resolving attacks. Understanding threat response times and security capabilities helps them refine their attack strategies.
Why Is This Bad For Businesses If The Data Is Fake?
By the time the public learns that the information is fake, the damage is often already done. For instance, in September 2023, Sony was targeted by a ransomware group that claimed to have breached the company's network and acquired its data. The alleged breach made headlines, tarnishing Sony's brand. By the time the investigation revealed the hacker's claim was false, irreparable damage had been done to the company's reputation.
What Can You Do To Prevent Fake Data Breaches?
To avoid becoming a victim of a fake data breach, consider the following steps:
- Actively Monitor The Dark Web: Ensure that you or your cybersecurity team routinely monitor the dark web. If you encounter an attacker selling your data, investigate the claim immediately to mitigate potential damage.
- Have A Disaster Recovery Plan In Place: Don't leave your team guessing about how to respond if a data breach occurs. Develop a communication plan in advance and refine it as needed.
- Work With A Qualified Professional: Focus on what you do best and leave IT-related issues to the experts. Partnering with a cybersecurity professional who knows how to identify, resolve, and prevent breaches takes the burden off your shoulders, ensures that monitoring and disaster recovery plans are in place, and provides peace of mind.
