Weak eMudra certificates triggered warnings about website impersonation

CyberWire Intel Briefing reported that researchers found 8 eMudra intermediate certificates with private keys weak enough to impersonate virtually any website.[1]

Cybersecurity Headlines said the compromised certificates could vouch for other certificates, prompting major browsers and apps to block them, while Edge on Windows 10 appeared exposed.[2]

TBPN focused on eMudra private keys as tiny as 4 and 56, noting one had apparently remained live for about a year and a half without apparent misuse.[3]

Risky Business discussed Mozilla revoking the certificates, including 6 for TLS and 2 for code signing, while questioning how the low-entropy keys were discovered.[4]

CyberWire Intel Briefing also reported that eMudra would stop issuing SSL certificates, offer free replacements to affected customers, and leave its other digital trust services unaffected.[5]
