Peach Sandstorm Targets US and UAE Critical Sectors with Tickler Malware

Between April and July 2024, Iranian state-sponsored group Peach Sandstorm deployed a custom backdoor called Tickler in intelligence-gathering operations against satellite, communications, oil and gas, and government sectors in the US and UAE. Their tactics included password spray attacks and LinkedIn-based social engineering. Tickler malware leveraged Azure infrastructure for command-and-control (C2) and utilized DLL files for persistence. Peach Sandstorm also accessed compromised Active Directory accounts to further exploit targeted environments. Their evolving tradecraft demonstrates a persistent focus on the intelligence sector, including higher education, government, and defense.
