Computer science graduate working as a software engineer at Penest-Tools.com, an online platform for penetration testing and vulnerability assessment used for discovering vulnerabilities in websites, network infrastructures, and, most recently, in the cloud, with the help of a tool developed by her and her colleagues.

AWS & GCP services vulnerabilities

Being up in the clouds is not alway secure. For our Master and Bachelor Thesis, me and a colleague researched vulnerabilities associated with the most popular cloud platforms: Amazon Web Services and Google Cloud Platform. The work has been integrated in the new, powerful tool on Pentest-Tools.com, called Cloud Vulnerability Scanner, and is still building up. Starting from how to detect the cloud provider behind a given address (AWS, GCP or Azure), we researched the ways you can find storage buckets associated with it, check their level of access (public or private, unauthenticated or authenticated, and their permissions: read, write, more or less), find users and misconfiguration, leading to a wide range of issues, from cost control to privilege escalation. To put it in a nutshell, we first have a recon phase, then for AWS and GCP we dived into the Storage service completely, while also tackling the IAM service for AWS.
