What Has CyberX9 Reported?

In its report dated November 21, 2021, the cybersecurity firm CyberX9 has stated that it discovered a highly critical security issue in the digital banking system of Punjab National.

Bank on November 17, 2021, giving access to the highest level privileges of administrator in an internal server of the lender.

This led to the exposure of over 180 million PNB users’ personal and financial information, and severely compromised the security of their funds for the past 7 months.

The report further added that this vulnerability in the bank’s server could have given any malicious attacker full access to the highest level of admin privilege.

The server is in a separate VLAN segment and customer data/applications are not affected due to this.
