Beyond Russia, the report also detailed actions taken by META against hacking group APT36, which operates out of Pakistan. The group targeted social media users in Afghanistan, India, Pakistan, the United Arab Emirates and Saudi Arabia, using various malicious tactics to infect devices with the malware.
