B2B USA Businesses

A massive dataset titled B2B USA Businesses containing over 105 million records was identified as exposed on the internet in mid-2017. This collection functioned as a comprehensive spam list targeting professionals across the United States. The breach surfaced due to an unsecured server or misconfigured database that allowed public access to sensitive corporate contact details. The data was organized to facilitate targeted marketing or phishing by categorizing individuals by their specific roles within various companies. The incident highlighted the vulnerability of large scale marketing aggregators and the risks associated with the unauthorized collection and storage of business contact information.
