    Project mention: Lessons Learned #3: Is your random UUID really random? (Account takeover with the sandwich 🥪 attack) | dev.to | 2025-01-19

    Use SAST and Linters: This kind of implementation issue could be detected automatically using tools SAST and Linters as the vulnerable functions are known. For example, in this case I couldn’t find a SAST rule to detect the usage of UUIDv1, but I took advantage of Semgrep’s Custom rules feature to add a rule to detect the usage of UUIDv1 in Python in the Semgrep Open source Rule Registry. Here is the Pull Request I submitted to add the rule https://github.com/semgrep/semgrep-rules/pull/3517 Here’s an example of findings generated by the new rule I added:
