Grep Extract Not Working Properly

Tim | Last updated: Mar 24, 2020 03:27PM UTC

Grep extract rules stopped working properly in recent versions. As recently as 2020.1 and still in 2020.2.1, creating a regex rule for a finished attack will not apply to the results, and string parsing rules only apply after enabling and disabling the rule after creation. When creating a regex rule, viewing the results and returning to the options tab shows a broken regex in the list of rules. Recreating the regex does not fix it and results in the same behavior. I have not tested this by creating the rule BEFORE the attack is run, so it may behave differently that way. Thanks!
