Tangem Resolves Security Flaw in Mobile App Exposing Private Keys

Cryptocurrency Wallet Provider Tangem Addresses Major Security Flaw

In a significant turn of events within the cryptocurrency space, Tangem, a prominent cryptocurrency wallet provider, has resolved a serious security flaw in its mobile application that raised concerns about users' private keys being exposed through email communications. This issue emerged after multiple users on Reddit highlighted the potential risks to investors' funds due to this security breach.

Background of the Security Flaw

The problem drew widespread attention on December 29, 2023, when a Reddit discussion accused Tangem of mishandling private keys. A user identified as u/areklanga criticized the company's lack of responsiveness when the issue was first flagged. This user claimed that private keys were being stored not only in user email histories but also in Tangem's internal email records and possibly within their ticket tracking system, making them potentially accessible to employees.

Tangem's Response to the Allegations

On December 30, Tangem officially acknowledged the security concern, stating that it stemmed from a bug in the mobile app's log processing. This bug caused private keys to be mistakenly logged during the wallet creation process when a seed phrase was involved. Consequently, these sensitive logs could inadvertently have been accessed by Tangem's support team during customer interactions.

The company moved quickly to rectify the issue, declaring that all relevant logs and attachments sent to their support team had been permanently deleted to ensure no residual data remained.

Scope of the Impact and Future Precautions

Tangem indicated that the flaw affected only a small number of users—specifically those who generated a seed phrase and immediately submitted a support request via the app. The company has taken the initiative to reach out to these affected users for additional caution and support.

Despite the critical patch released on December 30 to prevent future leaks, Tangem faced backlash from the cryptocurrency community for its generally muted response to the incident. As of December 31, there had been no official announcements from Tangem on their social media platforms, including Twitter, Discord, or Telegram.

Recommendations for Users

In light of this security breach, all Tangem users are strongly advised to update their mobile applications promptly to safeguard against potential seed phrase leaks.

Conclusion

The recent exposure of private keys through Tangem’s mobile application serves as a potent reminder of the importance of security in the cryptocurrency landscape. As Tangem works to restore user confidence, proactive measures and transparent communication will be key in navigating this incident.
