One significant risk arises from default permissions left open, which hackers can exploit using compromised contracts to extract tokens directly. Additionally, if your wallet interacts with unvetted smart contracts, attackers can utilize social engineering tactics to bait you into executing permissions unwittingly.
Real-World Case Study
[Security Insight Box] A 2025 incident illustrates a major hardware wallet firmware update that led to the leaking of user assets.
In early 2025, a popular hardware wallet experienced a security flaw following a firmware update. Users who had not revoked contract permissions were exploited through unauthorized transactions by malicious smart contracts. As a consequence, a significant amount of user funds went missing, cementing the necessity of proactive permission management.
