The activity has been pinned on an entity that's known as Emennet Pasargad, which the agencies said has been operating under the cover name Aria Sepehr Ayandehsazan (ASA) since mid-2024. It's tracked by the broader cybersecurity community as Cotton Sandstorm, Haywire Kitten, and Marnanbridge.
"The group exhibited new tradecraft in its efforts to conduct cyber-enabled information operations into mid-2024 using a myriad of cover personas, including multiple cyber operations that occurred during and targeting the 2024 Summer Olympics – including the compromise of a French commercial dynamic display provider," according to the advisory.
ASA, the U.S. Federal Bureau of Investigation (FBI), Department of Treasury, and Israel National Cyber Directorate said, also stole content from IP cameras and used artificial intelligence (AI) software such as Remini AI Photo Enhancer, Voicemod, and Murf AI for voice modulation, and Appy Pie for image generation for spreading propaganda.
Assessed to be part of Iran's Islamic Revolutionary Guard Corps (IRGC), the threat actor is known for its cyber and influence operations under the personas Al-Toufan, Anzu Team, Cyber Cheetahs, Cyber Flood, For Humanity, Menelaus, and Market of Data, among others.
Microsoft, in a report published last week, called out Cotton Sandstorm for engaging in "reconnaissance and limited probing" of election-related websites in some U.S. swing states in April 2024. It has also been associated with reconnaissance activities targeting major U.S. media publications in May 2024.
One of the newly observed tactics concerns the use of fictitious hosting resellers to provision operational server infrastructure for its own purposes as well as to an actor in Lebanon for hosting Hamas-affiliated websites (e.g., alqassam[.]ps).
"Since approximately mid-2023, ASA has used several cover hosting providers for infrastructure management and obfuscation," the agencies said. "These two providers are 'Server-Speed' (server-speed[.]com) and 'VPS-Agent' (vps-agent[.]net)."
"ASA set up its own resellers and procured server space from Europe-based providers, including the Lithuania-based company BAcloud and Stark Industries Solutions/PQ Hosting (located in the United Kingdom and Moldova, respectively). ASA then leverages these cover resellers to provision operational servers to its own cyber actors for malicious cyber activities."
The attack directed against the unnamed French commercial display provider took place in July 2024 using VPS-agent infrastructure. It sought to display photo montages criticizing the participation of Israeli athletes in the 2024 Olympic and Paralympic Games.
Furthermore, ASA is alleged to have attempted to contact family members of Israeli hostages following the Israeli-Hamas war in early October 2023 under the persona Contact-HSTG and send messages likely to "cause additional psychological effects and inflict further trauma."
The threat actor has also been linked to another persona known as Cyber Court, which promoted the activities of several cover-hacktivist groups run by itself on a Telegram channel and a dedicated website set up for this purpose ("cybercourt[.]io").
