As India’s Top Hospital AIIMS Remains Hit By Ransomware, A Look At Some Major Cyber Attacks



As India’s Top Hospital AIIMS Remains Hit By Ransomware, A Look At Some Major Cyber Attacks

The All India Institute of Medical Sciences (AIIMS) in Delhi has come under a major ransomware attack with the culprits demanding around Rs 200 crore in cryptocurrencies as the threat continued for almost a week now.

What’s more worrying is that the data of three to four crore patients of the government-run facility could have been compromised due to the cyber security breach at the premier health care institute, according to reports.

Ransomware Explained
Currently, ransomware attacks are among the biggest cyber threats in India. In simple words, a ransomware attack is a type of cyber invasion wherein attackers access the victim’s system and encrypt sensitive data by deploying malicious software and asking for a “ransom” to restore access to files.

Notably, a report by India’s cyber security watchdog CERT-In recently mentioned that there has been a 51% rise in ransomware attacks in the first half of 2022 as compared to 2021.
Not only the first half, there have been multiple cyber attacks in the second half of this year that have kept cyber authorities on their toes.

How Is It Happening?

As technology advances, cyber attacks have also become more sophisticated with hackers using new tools and technologies to bypass even the most cutting-edge of securities.
It’s no surprise that experts have predicted that the number of such attacks is likely to only go up in the coming days.

According to a report by cyber threat intelligence firm CloudSEK, the Indian healthcare industry has been hit by the second-highest number of cyberattacks worldwide and over 71 lakh records have been compromised.

Some Of The Biggest Ransomware Attacks In India:

AIIMS Server Down

This is the latest in the attacks. The digital services of AIIMS Delhi have been down since November 23. The hospital was hit by a major ransomware attack and its officials have blamed a weak firewall, outdated systems and lack of cloud-based servers as the reason for the cyber attack.

They also suspected that Chinese hackers might be behind the attack, which has impacted basic daily operations like appointments, admissions and billing systems.
While the country’s premier healthcare institution is still trying to get its systems online with the help of the National Information Centre (NIC), along with CERT-In, it has deployed additional staff to manually run basic services.

SpiceJet later took to social media as it confirmed that their IT team had contained and rectified the situation and flights had started operating normally. The threat and its impact was short-lived but had thrown thousands of passengers into tizzy, while the airline and its management were obviously worried over the cyber attack.

Oil India

A month before the Spicejet attack, government-owned Oil India (OIL) faced a major cyber-attack in Assam. OIL officials confirmed that the hacker demanded over Rs 57 crore as ransom.
The company’s server, network, and other related services were affected. According to a news report, the hack involved a Russian malware planted from a server in Nigeria.
However, OIL later stated that it didn’t suffer any financial losses and the company’s operations were running smoothly.

Hackers used the “Robinhood” ransomware to attack the computer systems of power distribution companies located in Telangana and Andhra Pradesh in 2019.
The attackers also demanded six Bitcoins (which was approximately Rs 24 lakh at that time) to restore access to data of the companies in both states. This attack endangered the data of about 3.5 lakh consumers who visited the websites.
