When AWS keys were exposed in GitHub repositories, GitHub responded by invalidating those keys. Researchers at Digital Shadows have found that this proper action doesn't end the issue of exposed keys as they have found almost 800,000 keys available on the Web.
The researchers searched approximately 150 million entities across GitHub, GitLab, and Pastebin during a 30-day period in August and September to find the roughly 800,000 keys. They discovered that more than 40% of the keys were database keys while 38% were for cloud services. Redis was the most common database involved, while Google Cloud API was the most common cloud service key.
In their blog post on the research, Digital Shadows notes three services — Trufflehog, GitRob, and GitHub Secret Scanning — that can help organizations search for their own keys that might have been exposed online.
