What is Wannacry? What is ransomware? How to stay safe from cyber attacks?
BT Online May 15, 2017
A ransomware going by the name 'Wannacry' has become a global cyber-threat and India is as vulnerable as any affected country . The biggest problem with such ransomwares is that there is no well-known way to deal with it; even paying the ransom cannot guarantee that the files will be recovered.
What is Ransomware?
The biggest threat with 'Wannacry' is that it's more than just a ransomware; it can also be classified as a worm. Being a worm, the ransomware has the ability to spread to different systems running on the same LAN network or even spread through emails.
India was among the countries worst affected by the Wanna Cry attack, data shared by Kaspersky, a Russian anti-virus company, showed. According to initial calculations performed soon after the malware struck on Friday night, around five per cent of all computers affected in the attack were in India.
News agency IANS reported that police computers across 18 units in Andhra Pradesh's Chittoor, Krishna, Guntur, Visakhatpatnam and Srikakulam districts were affected. However, apart from that, there was no immediate information on the extent of the ransomware's hold on Indian systems.
What can be done if you're a victim to a ransomware cyber attack?
Though there is no way out, there are a few loopholes one could use to either minimise the damage or stop it from spreading.
Since the encryption does not happen instantly, the user should immediately try to back-up the essential files as soon as possible. This will help minimise the damage.
According to CERT-In, victims of the ransomware are advised not to pay the ransom as there is no gaurantee that the files will be returned. Instead, report any such case with CERT-In at Incident@cert.org.in and other law enforcement agencies.
