WatchTowr warned that breaches of this magnitude may surpass the notorious 2020 SolarWinds assault in scale and influence. Among the incidents uncovered by watchTowr are a number of alarming examples:
- Abandoned S3 buckets tied to SSL VPN equipment distributors had been found to be nonetheless serving deployment templates and configurations.
- An older GitHub commit from 2015 uncovered an S3 bucket linked to a well-liked open supply WebAssembly compiler.

The incontrovertible fact that these massive organizations had been nonetheless counting on mismanaged or forgotten sources is a testomony to the pervasive nature of this oversight.
