Breach Exposure of London's FTSE 100

FTSE 100 Breach Exposure Report

Even employees at the world’s largest and most successful organisations use weak passwords, and frequently reuse corporate credentials as personal logins, regardless of security guidelines that prohibit such behavior. When those third-party sites are subject to data breaches, reused employee logins provide easy entry points to corporate systems and networks.

To provide a snapshot of the breach exposure affecting major enterprises, we examined SpyCloud’s entire database to see what exposed data we could tie to FTSE 100 companies and their subsidiaries. We found over 39 million breach assets, including 2.6 million plaintext credentials, tied to these employees. All of this data is available to cybercriminals and can be used for malicious purposes.
