Ransomware Attacks In India

Nobody has forgotten the chaos created by the “WannaCry” Ransomware attack all around the world, owing to its lateral movement. It was immensely powerful and had silently penetrated the networks, gradually spreading in all the far and near countries. This had alarmed the security community, which was very quick in taking down all the infrastructure that was linked with WannaCry. It was successful to a great extent and the security community did relieve the people of this dangerous ransomware – but it was not enough.

Owing to the ransomware’s stability across networks, the latest scan performed by eScan has observed that the Ransomware attacks in India have not completely perished – it still exists, albeit, in dormant form. Nonetheless, that doesn’t make it less hazardous.

On a regular basis now, eScan’s telemetry servers have been observing and recording WannaCry ransomware’s reminiscent artefacts. You need not panic, however, in the last few months, the cases involving WannaCry have come down steadily. Seeing the uniform decrease, we can hope that by this year-end, WannaCry would completely retreat, meeting the same fate encountered previously by Conflicker Worm or DNS Changer Botnet.

On the other hand, a lot of newer variants of the Ransomware have been added in the family over the period of last few years. However, most of them did not go through active development, while a very few like GandCrab and ZZZ* did. Over the period of the last few weeks, GandCrab, first spotted on January 26, 2018, has acquired a centre-stage and is growing at a very rapid rate. It implies that the Ransomware Developer / Criminal nexus is acquiring more power and is getting stronger with passing days. Besides, a lot of cyber-criminals are now changing their loyalties to GandCrab – just because of the blunt fact that the developers are portraying a lot of interest in this Ransomware, with adding numerous weapons to its arsenal.
