Title: Indian human rights advocates targeted by NetWire malware

Description: Attackers targeted several human rights activists in India between January and October of 2019 with the NetWire malware, attempting to intercept their communications. Researchers say the victims opened spear-phishing emails, which eventually led to the infection. NetWire can steal users' audio recordings, steal credentials and log keystrokes. All the targets are advocating for the release of protestors who were jailed after demonstrations in 2018.
