Inside Ledger Donjon lab, experts assess smartphone chip security

In a growing backlash, users are voicing serious concerns about Ledgerโ€™s commitment to security following the Donjon lab's recent findings. Many are calling for accountability related to ongoing issues with Changelly, which has shaken trust among crypto enthusiasts.

A Closer Look at the Security Findings

Ledger's internal team, Donjon, has been at the forefront of revealing vulnerabilities in critical hardware and software systems, emphasizing the importance of proactive security measures. Their rigorous testing has highlighted several devices' weaknesses, particularly in the realm of physical security and software integrity.

Another poignant remark echoed a prevailing distrust: "Nobody cares. You might have a great team but business practices suggest we should not trust you." Such comments underscore a clear demand for transparency from Ledger and a reassessment of their business approach.

"Trust is a primary factor in finance and security. Without it, companies should be boring and trustworthy," lamented a concerned community member.
