Hardware wallet provider Trezor has patched up a security flaw in two of its latest models after competitor firm Ledger’s open-source research arm discovered a vulnerability in their microcontrollers.
Ledger Donjon acknowledged Trezor has made several security advancements of late but found cryptographic operations could still be performed on the microcontroller of Trezor’s Safe 3 and 5 models, which could make them “vulnerable to more advanced attacks.”
Fortunately, Trezor has since addressed the vulnerabilities found, Ledger’s chief technology officer Charles Guillemet said in a March 12 X post.
