variant_analysis

Variant analysis identifies and locates variants of known security vulnerabilities by abstracting vulnerability patterns and performing targeted searches across the codebase. This multiplies the value of a single security finding by automatically locating similar vulnerabilities.

Performing a variant analysis is the best way to find missing payable checks in MultiversX smart contracts. The process abstracts the vulnerability pattern and leverages tools like grep to locate all occurrences of the issue across the codebase.

Yes, you can automate detection by creating temporary Semgrep rules based on abstracted vulnerability patterns. This integration facilitates automated detection of identified variants across the entire codebase.

Variant analysis detects unbounded mapper iterations by addressing common MultiversX-specific issues through pattern abstraction. It identifies the core pattern of the vulnerability beyond its specific instance and searches the codebase for matching occurrences.

No specific tool is strictly required, as variant analysis can leverage tools like grep for codebase-wide search. However, integrating with static analysis tools like Semgrep facilitates automated detection of identified async callback revert variants.
