Charming Kitten (TA453) employs sophisticated techniques to infiltrate critical sectors.

A state-sponsored Iranian hacking group, known as Charming Kitten or TA453, has recently launched a targeted attack against a nuclear security expert affiliated with a US-based think tank. This latest operation is part of the group’s ongoing cyber espionage activities, which have previously targeted high-value accounts in government, academia, NGOs, national security, and journalism.

In this specific attack, TA453 utilized a benign email to establish a relationship with the target, followed by a subsequent email containing a malicious macro. The macro directed the victim to a Dropbox URL hosting a .rar file. This deviation from the group’s typical infection chain involved the use of an LNK file, which employed PowerShell to download additional stages from a cloud hosting provider.

According to a recent analysis by Proofpoint, the adoption of Google Scripts, Dropbox, and CleverApps highlights TA453’s ongoing commitment to a multi-cloud approach, likely intended to minimize detection efforts. The group continues to deploy modular backdoors to gather intelligence from highly targeted individuals.

This latest revelation follows Microsoft’s warning in April about Iranian hackers targeting critical infrastructure in the United States, including transportation, energy, and ports. The threat group, referred to as “Mint Sandstorm,” has been linked to TA453. Microsoft’s Threat Intelligence report detailed the subgroup’s initial reconnaissance efforts, which eventually escalated to attacks on critical infrastructure organizations in the US in 2022.

In November 2021, the US Justice Department indicted two Iranians, Mohammad Hosein Musa Kazemi and Sajjad Kashian, who were employed by Emennet Pasargad. These individuals were allegedly involved in a cyber campaign during the 2020 presidential election aimed at intimidating and influencing American voters.

As the activities of state-sponsored Iranian hacker groups persist, organizations operating within critical sectors should remain vigilant and enhance their cybersecurity measures to protect against sophisticated attacks. The targeting of nuclear security experts underscores the need for heightened security measures to safeguard sensitive information and critical infrastructure from cyber threats.
