MeitY: Ransomware incidents targeting ‘critical infrastructure’ have grown: MeitY | #hacking | #cybersecurity | #infosec | #comptia | #pentest | #ransomware

Ransomware incidents have grown over time with attacks across multiple sectors, including commercial and “critical infrastructure,” the government said in response to a question posed in the Lok Sabha on Wednesday regarding the AIIMS cyber attack.

“Threat actors have modernised their attack methodologies, evolved sophisticated tactics and adopted a wide range of attack campaigns,” Rajeev Chandrasekhar, Minister of State for Electronics & Information Technology, said in a written response to an unstarred question.

“Ransomware actors exploit known vulnerabilities, compromised credentials of remote access services and phishing campaigns for gaining access into the infrastructure of organisations,” he added.

While the minister did not divulge any further details on the extent of the breach, he said that five servers of AIIMS were affected. Further, he added that as per preliminary analysis, the servers were compromised by “unknown threat actors” due to improper network segmentation which caused operational disruption due to non-functionality of critical applications.

Chandrasekhar said a special advisory on security practices to enhance resilience of health sector entities has been communicated by the Indian Computer Emergency Response Team (CERT-In) to the Ministry of Health and Family Welfare, for sensitising health sector entities regarding latest cyber security threats.

The ministry has been requested to disseminate the advisory among all authorised medical care entities and service providers in the country.

Ransomware attacks are carried out by installing malware in the target computer, which encrypts valuable data in the system. Cybercriminals then demand a ransom – typically in cryptocurrency to ensure anonymity – to decrypt the data. Some kinds of ransomware malware don’t encrypt data, they simply lock down the target system to make it inaccessible.
