Islamabad (The COW News Digital) Pakistan has issued a cybersecurity warning over potential attacks targeting government departments, financial institutions and other critical digital infrastructure, following the discovery of vulnerabilities involving digital security certificates issued by eMudhra.
The National Cyber Emergency Response Team has released an advisory urging relevant organisations to take immediate protective measures to reduce the risk of cyberattacks and safeguard sensitive information.
According to the advisory, weaknesses affecting eight private security keys associated with eMudhra’s certificate authority have raised concerns about the security of online systems. Six of the affected keys are linked to Transport Layer Security (TLS) certificates, while two are used for code-signing purposes.
Digital certificates play an important role in establishing trust between websites, software applications and users. They help verify the identity of online services and protect information exchanged over digital networks. If the security keys used to issue these certificates are compromised, attackers may be able to exploit that trust.
The advisory warns that the vulnerabilities could potentially allow malicious actors to create fraudulent digital certificates, imitate legitimate websites and online services, intercept internet traffic, monitor communications or manipulate data.
Such activities could expose government systems, banking networks and other sensitive digital infrastructure to significant security risks. Fake certificates could also make it more difficult for users and organisations to distinguish legitimate online services from malicious imitations.
The warning highlights the importance of addressing certificate-related vulnerabilities promptly, particularly in organisations that handle confidential information or operate essential public services.
The National Cyber Emergency Response Team has instructed relevant institutions to update their operating systems, internet browsers and software without delay. Organisations have also been advised to block affected certificates and update their security trust stores to prevent reliance on compromised credentials.
The advisory further stresses that protective measures should extend beyond standard computer systems. Mobile applications, desktop software and other digital platforms that maintain separate certificate stores may also require individual security checks and updates.
Organisations have been urged to review their systems carefully to ensure that vulnerable certificates are no longer trusted where appropriate. Failure to address weaknesses across different applications and devices could leave gaps in an otherwise effective security response.
The advisory also calls for increased monitoring of suspicious certificates, unusual network activity and unexpected connection redirects. These warning signs may help security teams identify possible attempts to exploit compromised certificates or interfere with communications.
Any suspected incident involving fraudulent certificates or data interception should be reported to National CERT Pakistan, according to the advisory. Prompt reporting can help cybersecurity authorities assess potential threats and coordinate an appropriate response.
The warning serves as a reminder that digital certificate security is an essential part of protecting online transactions, government communications and critical information systems. Financial institutions and public-sector organisations, in particular, rely on trusted digital connections to deliver services and exchange sensitive data.
Cybersecurity experts generally recommend timely software updates, careful certificate management, continuous network monitoring and coordinated incident reporting to reduce exposure to such threats.
While the advisory identifies potential risks, it does not establish that all the targeted institutions have already suffered successful cyberattacks. The immediate priority is to address the reported vulnerabilities, strengthen digital safeguards and monitor systems for suspicious activity.
Pakistan’s latest warning underscores the need for organisations to treat certificate security as a critical operational responsibility amid evolving cyber threats.
