@Unik0rnMaggie Linea may not be fully supported yet. I see the same behavior in prod and in RC 12.5.0:

Malicious ERC20 transfer (USDC) - not flagged;
Malicious ERC20 Approval (BUSD) - not flagged;
Malicious Set Approval for All - not flagged
Malicious ERC 20 Approval with Odd Hex Data - not flagged
Sign Permit -not flagged
