CIBanco detected ransomware attack; some operations have been restricted

The banking institution claims that the data and assets of its customers are safe

According to network security and ethical hacking specialists from the International Institute of Cyber Security, the IT teams of CIBanco detected the presence of a malware on the computer of one of its employees. The bank implemented certain security measures, such as the restriction of some operations, as well as notifying the relevant authorities.

Through a statement, CIBanco mentioned: “As established in our security protocol, we have restricted banking operations and have brought the situation to the financial authorities”.

The bank also stated that the resources of the clients, those of the bank itself, and the protected information pertaining to both parties, have not been compromised. According to network security specialists, CIBanco will maintain active its security protocols until the security of operations is guaranteed.

This is the second time in less than a week that some institution of the Mexican banking system is affected by a cybersecurity incident. Last Friday was Invercap’s turn, which notified the authorities about an unsuccessful cyberattack attempt.

The Mexican National Banking and Securities Commission (CNBV) confirmed the incident happened at CIBanco, stressing that “the attack was contained shortly after its detection”. CIBanco notified the competent authorities in compliance with the communication protocol established between judicial and financial authorities and banking sector members in Mexico.

According to specialists in network security, the malware detected in CIBanco systems is a variant of ransomware based on Windows systems. The CNBV confirmed that the incident had no economic impact, affecting only “some PCs of bank employees”.
