WannaCry Ransomware

16 May 2017


There has been a lot of attention around "an international ransomware attack" in the media right now. This ransomware called WannaCry (or WannaCrypt, WanaCrypt0r 2.0, Wanna Decryptor) encrypts the computer's hard disk drive and then spreads laterally between computers on the same LAN. This attack spreads by multiple methods, including within word documents, PDFs and other files normally sent via phishing emails and on unpatched systems as a computer worm.

On Friday, 12 May 2017, a large cyber-attack was launched, infecting over 230,000 computers in 150 countries, demanding ransom payments, reported by Wikipedia. India was among the countries worst affected by the WannaCry 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.
