Just when it seems like cybercriminals have exhausted their bag of tricks, they manage to innovate and catch us off guard. Their latest ploy involves faking data breaches, aiming to defraud both unsuspecting business owners and dark web data buyers.
Earlier this year, Europcar, a prominent international car rental company from France, uncovered a cybercriminal selling what was purported to be private information on over 50 million of its customers on the dark web. Upon launching a formal investigation, Europcar discovered that the data being sold was fake, likely generated using advanced tools like generative AI.
How Do They Pull It Off?
With AI-powered tools such as ChatGPT, cybercriminals can swiftly create realistic-looking data sets. These savvy criminals conduct thorough research to design data sets that appear legitimate, featuring correctly formatted names, addresses, emails, and even matching local phone numbers. They also leverage online data generators, originally intended for software testing, to produce large volumes of authentic-looking fake data. Once armed with these fabricated data sets, hackers choose a target from whom they claim to have stolen the data and then post this information on the dark web.
Why Are They Doing This?
Why would a hacker go to the trouble of faking a data breach? There are several motivations, beyond the obvious benefit of reaping rewards without the effort of breaching a network's security.
- Creating Distractions: One effective way to weaken a company's defenses is to divert its attention. By focusing on a supposed breach, the company may overlook a real attack from another angle.
- Bolstering Their Reputation: Within the hacker community, reputation is crucial. Targeting a well-known brand publicly can earn them notoriety and recognition from other hacker groups.
- Manipulating Stock Prices: For publicly traded companies, a data breach can cause a swift 3% to 5% (or more) drop in stock prices. This can create panic, allowing cybercriminals to manipulate stock prices for financial gain.
- Learning Security Systems: Faking a data breach can provide cybercriminals with valuable insights into a company's security protocols for preventing, detecting, and resolving attacks. Understanding the threat response time and security capabilities can help them refine their attack strategies.
Why Is This Harmful to Businesses Even If the Data Is Fake?
By the time the public learns that the information is fake, significant damage may already be done. For instance, in September 2023, Sony was targeted by a ransomware group that claimed to have breached its network and acquired its data. The breach made headlines, tarnishing Sony's reputation. By the time it was revealed that the hacker's claim was false, the damage to Sony's brand was already irreparable.
How Can You Prevent Falling Victim to Fake Data Breaches?
To avoid becoming a victim of a fake data breach, consider the following steps:
- Actively Monitor the Dark Web: You or your cybersecurity team should routinely monitor the dark web. If you encounter someone selling your data, investigate the claim immediately to mitigate potential damage.
- Have a Disaster Recovery Plan in Place: Ensure your team knows exactly what to do and say if a data breach occurs. Develop and fine-tune this communication plan in advance.
- Work with a Qualified Professional: Focus on your core business activities and leave IT-related issues to the experts. Partnering with a cybersecurity professional who knows how to identify, resolve, and prevent breaches can provide peace of mind and ensure that steps #1 and #2 are effectively managed.
