Over 600,000 persons were impacted by a data leak that took place at another background check company. Compared to the 2.9 billion persons impacted by the National Public Data theft, this is a minor breach, but it's still concerning. SL Data Services, the company in question, was discovered online. It was neither encrypted or password-protected and was available to the public.
Jeremiah Fowler, a cybersecurity researcher, uncovered the breach (or lack of protection on the files). Full names, residences, email addresses, employment data, social media accounts, phone numbers, court records, property ownership data, car records, and criminal records were all leaked.
Everything was stored in PDF files, the majority of which were labelled "background check." The database had a total of 713.1GB of files. Fortunately, the content is no longer publicly available, however it took some time to be properly secured. After receiving the responsible disclosure warning, SL Data Services took a week to make it unavailable.
A week is a long time to have 600,000 people's information stored in publicly accessible files. Unfortunately, those with data in the breach might not even know their information was included. Since background checks are typically handled by someone else, and the person being checked rarely knows whose background check company was utilised, this might become even more complicated.
While social security numbers and financial details are not included in the incident, because so much information about the people affected is publicly available, scammers can use it to deceive unsuspecting victims using social engineering.
Thankfully, there is no evidence that malicious actors accessed the open database or obtained sensitive information, but there is no certainty that they did not. Only time will tell—if we observe an increase in abrupt social engineering attacks, we know something has happened.
