Why it matters: stability scientists have found the same list of firmware vulnerabilities they uncovered in Fujitsu Lifebook programs in fact have an effect on several more gadgets from a number of vendors. the failings are significant as they allow attackers to bypass hardware safety features together with standard endpoint stability solutions.
This is a brutal provide chain failure, exposing how sloppily some distributors have taken care of significant System safety. difficulties vary from reusing precisely the same keys throughout purchaser and company product lines, shipping and delivery solutions with non-generation cryptographic material, and failing to rotate keys consistently.
