IT, computing & emerging technologies Easy

The terms ‘WannaCry, Petya and EternalBlue’ sometimes mentioned in the news recently are related to

Answer & explanation

Answer: (c) Cyber attacks

All three names belong to cyber attacks in 2017. WannaCry and Petya are ransomware, meaning malware that locks a victim's files, and EternalBlue is the Windows exploit through which they spread.

  • ✓ (c) WannaCry encrypted files on infected Windows systems and spread through a Windows Server Message Block vulnerability, an exploit named EternalBlue. Variants of Petya ransomware later spread using the same exploit. India's CERT-In issued alerts for both in 2017.
  • ✗ (b) These are malicious programs and an exploit, not digital currencies. CERT-In classifies WannaCry and Petya as ransomware.
  • ✗ (a) Exoplanets are planets outside the Solar System and have no connection with these computer-security terms.
  • ✗ (d) Mini satellites are small space vehicles. WannaCry, Petya and EternalBlue are software threats.

Remember · WannaCry and Petya = ransomware (2017). EternalBlue = the Windows SMB exploit that helped them spread. CERT-In is India's nodal agency for such alerts.
