Slow Mist founder Cosine posted on social media that in the low state of Ethereum gas (0.347 Gwei), it is recommended that investors cancel all token authorizations that are uncertain/incomprehensible/think they are safe, and cancel a single authorization. Gas is less than $0.10, even if there are 100 abnormal authorizations to cancel, it only costs a few dollars, but it blocks the potential huge risk exposure.
