Over the last few years there have been multiple examples of leaky cloud services, exposing million of user records (with easily predictable consequences for the privacy of the unaware victims), or even fueling other attacks such in case of the two Magecart campaigns carried out compromising the AWSS3 buckets hosting the targeted sites’ configuration files.
And despite AWS S3 is the most common service to leak data, it’s not the only one, as you will notice. Last but not least, I will keep this list updated as soon as new cloud breaches will be revealed during 2021.
As always, thanks for sharing and supporting my work for spreading the risk awareness across the community. Also, don’t forget to follow @paulsparrows on Twitter, or even connect on Linkedin.
