Every Cyber Attack Is A wake-up Call For The Nation

By Sanjay Kaushik: Every individual, business, corporate, institution, and government are today under the threat of cyber attacks. More and more use of technology and its evolution gives space to cyber crime. Such crimes have taken over all the other crimes in terms of rise and loss in terms of value. It is the most dangerous attack today as the criminals capitalise on vulnerable security systems for their gain and the victim has no idea about them.

It can strike you anywhere and anytime. From an individual to a government organisation, all are under attack and hence every attack needs to be dealt as an attack on the nation. Every attack is a wake-up call for the nation.

It is presumed that data of millions of patients might have been compromised and operations at AIIMS remain affected. With AIIMS servers already hacked, the cyber attackers intensified the attacks on other health and research organisations website tried to hack Indian Council of Medical Research’s (ICMR) website for more than 6000 times in a span of 24 hours, but were not successful.

Ransomware attacks are among the biggest cyber threats in the VUCA world. Ransomware is something similar to like kidnapping. In earlier days, it was the person who was kidnaped and Ransom was demanded. In the current cyber world, its data which is encrypted (Kidnapped) and Ransom is demanded to decrypt the data. The ransom payment may guarantee the return of kidnapped person. But it is more dangerous in the cyber world. One might get decryption key post paying Ransom but the attacker might decide to sell the data in dark web a few months later.

As per CERT-IN report, there is approx. 51% hike in ransomware attacks in the first 6 months of 2022 in comparison to the previous year and it is ever-increasing.

We had a couple of companies that approached us recently both were planning for their IPOs and were under Ransomware attack. In one of the case, all the servers were encrypted and entire operation was severely impacted. They hired us to help them get out of this entire incident. It took couple of days and they were required to even get the insurance company into play to get this issue resolved.
