Microsoft is highlighting new state-sponsored attacks originating from Iran, specifically targeting employees within the US defense industrial base (DIB) organizations. These attacks are attributed to Peach Sandstorm, also known as APT33, a group believed to be backed by the Iranian government and active across various sectors globally since at least 2013.
