Ongoing Coldcard Wallet Attacks Target Remaining Seed Phrases

The cybersecurity landscape for hardware wallet users remains tense as Alex Thorn, Head of Research at Galaxy, reports that attacks targeting Coldcard wallets are continuing. Recent findings indicate a shift in the threat profile, with smaller-scale actors and imitators now focusing on users who have yet to secure or migrate their seed phrases. These persistent efforts highlight a growing trend of "copycat" exploits following larger, more coordinated security breaches within the Bitcoin ecosystem.

New Wave of Imitators and Identity Tracking

While previous investigations by Galaxy Research identified three major waves of attacks—categorized as Wave 1, Wave 2, and Wave 3—the current activity appears to be the work of fragmented groups. These attackers utilize methods similar to those of their predecessors, aiming to exploit the remaining vulnerable accounts. Thorn noted that a specific incident involved funds transferred through the Duel platform. Although the assets were moved before a freeze could be initiated, the platform has successfully retrieved the identity information of the user involved in the deposit, providing a potential lead for law enforcement.

Strategic Security Risks for Wallet Holders

The emergence of imitators suggests that the technical blueprints for these attacks are being replicated by less sophisticated actors. This democratization of exploit methods poses a long-term risk to users of non-custodial hardware solutions who do not follow updated security protocols. Galaxy Research emphasizes that these current incidents are distinct from the primary three attack waves, indicating a diversification of the threat landscape.

• Target Audience: Users who have not yet migrated assets or updated seed phrases.
• Attacker Profile: Small-scale entities and "imitators" replicating known exploits.
• Incident Scope: Independent of the initial major attack waves identified by Galaxy.

Smaller-scale attackers and "imitators" replicating previous attack methods have appeared in the market, targeting those who have not yet migrated their assets.

In conclusion, the persistence of these attacks serves as a critical reminder for the cryptocurrency community regarding the importance of proactive asset management. As blockchain forensics and platform cooperation improve—evidenced by the identification of users on the Duel platform—the window for attackers to operate anonymously is narrowing. However, the primary responsibility remains with the user to ensure that their private keys and recovery phrases are protected against both sophisticated groups and emerging imitators.
