Talos continuously monitors malicious emails campaigns. We identified one specific spear phishing campaign launched against targets within Palestine, and specifically against Palestinian law enforcement agencies. This campaign started in April 2017, using a spear phishing campaign to deliver the MICROPSIA payload in order to remotely control infected systems. Although this technique is not new, it remains an effective technique for attackers.
