A public leak tied to Charming Kitten, the Iranian threat group also tracked as an IRGC-linked operation, exposed material described as documenting the group's malicious activity and its connection to the IRGC-IO counterintelligence division known as 1500. A GitHub repository published under the name KittenBusters/CharmingKitten presented the leak as evidence of the group's internal operations, adding to public scrutiny of one of Tehran's most prominent cyber-espionage actors.
Follow-on reporting said the leak continued with the release of payroll data and a stolen IAEA document, suggesting the exposed archive extended beyond operational details into sensitive internal records and potentially intelligence-related material. The disclosures indicate a sustained effort to reveal the infrastructure, personnel, and document holdings associated with Charming Kitten, raising counterintelligence and diplomatic concerns around the handling of stolen data linked to an Iranian state-aligned cyber unit.

A later blog post stated that the Charming Kitten leak was continuing and described the release of payroll data along with a stolen IAEA document, indicating a further disclosure of allegedly compromised materials.
A blog post published by Nariman Gharib described alleged details about IRGC Department 40, presenting it as a unit connecting cyber operations to assassination activity. The post appears to represent a new phase of disclosures following the initial Charming Kitten repository publication.
A GitHub repository titled "KittenBusters/CharmingKitten" was published, presenting materials that purported to expose malicious activity linked to Charming Kitten and the IRGC-IO counterintelligence division known as Unit 1500.

A significant leak of internal operational documents allegedly belonging to the Iranian state-sponsored threat group APT35, also known as Charming Kitten, has surfaced online. The dataset, which appeared on a public repository in late September 2025, contains over 100 files of Persian-language internal documentation, including personnel rosters, tooling details, campaign reports, and organizational charts. Analysis of the leak reveals a highly coordinated structure within APT35, with dedicated teams for penetration testing, malware development, social engineering, and infrastructure compromise. The documents detail the group’s rapid exploitation of vulnerabilities such as CVE-2024-1709 and their use of mass router DNS manipulation to compromise targets. Victims identified in the leak span government, legal, academic, aviation, energy, and financial sectors, primarily in the Middle East, but also include targets in the United States and Asia. The operational materials highlight the group’s use of custom remote access trojans (RATs), advanced endpoint detection and response (EDR) evasion techniques, and supply-chain attack vectors. The leak also exposes the group’s sophisticated phishing infrastructure and their ability to achieve long-term persistence and Active Directory dominance within compromised environments. The documents provide insight into the group’s vulnerability research activities, targeting platforms such as Confluence, WordPress, Ivanti, and Apache. Additionally, the leak includes open-source intelligence (OSINT) on targets and detailed attack reports, including domain information and mentions of remote access tools like Anydesk. The individual or group responsible for the leak, operating under the alias KittenBuster, has stated their intention to release further evidence and personal information about APT35 members in the coming days. Security researchers are working to verify the authenticity of the leak, but initial assessments indicate a high degree of credibility based on language, content, and context. The exposure of these materials represents a rare and valuable opportunity for the cybersecurity community to gain insight into the tradecraft, organizational structure, and operational priorities of a major Iranian cyber-espionage group. The leak underscores the acute supply-chain and national security risks posed by IRGC-affiliated actors and highlights the need for heightened vigilance among organizations in targeted sectors. The ongoing release of additional documents may further illuminate the group’s tactics, techniques, and procedures (TTPs), enabling defenders to better anticipate and mitigate future threats. This incident marks one of the most comprehensive public exposures of Iranian APT operations to date, with potential implications for both regional and global cybersecurity.

Reporting describes two separate **Iran-linked espionage** efforts. HarfangLab detailed a campaign dubbed **RedKitten** targeting human-rights NGOs and individuals documenting abuses, using a lure delivered as a Farsi-named `7z` archive containing macro-enabled Excel (`.xlsm`) files. When victims enable the malicious VBA, it drops a C# implant (`AppVStreamingUX_Multi_User.dll`) via **AppDomainManager injection**; the operation uses **GitHub** and **Google Drive** for configuration/payload retrieval and **Telegram** for command-and-control, and researchers noted code characteristics consistent with **LLM-assisted** development. Separately, Pulsedive research (as summarized) attributed a PowerShell backdoor called **TAMECAT** to **APT42**, describing social-engineering via impersonated WhatsApp contacts and links abusing the `search-ms` URI handler, followed by VBScript-based staging and delivery mechanisms including WebDAV-hosted LNKs disguised as PDFs. TAMECAT was reported to steal credentials from **Microsoft Edge** and **Chrome**, establish persistence (e.g., logon scripts and registry run keys), and use multiple C2 channels (including **Telegram**, Discord, Firebase, and Cloudflare Workers). Other items in the set cover unrelated events: a supply-chain compromise of *eScan* antivirus update infrastructure distributing a backdoor, and Fortinet’s reporting on **Interlock** ransomware activity affecting primarily UK/US organizations (not Iran-linked).

State-backed advanced persistent threat (APT) groups have intensified their cyber espionage activities, employing increasingly sophisticated tactics, techniques, and procedures (TTPs) to infiltrate and persist within high-value targets. APT15, believed to operate out of China, has conducted a series of high-profile campaigns targeting government entities, defense contractors, and minority groups across Europe, North America, and Asia. Their operations leverage spear phishing, exploitation of public-facing applications, and advanced defense evasion methods such as steganography and masquerading malware as legitimate software. Similarly, the Iranian group Charming Kitten (APT35) has been exposed through recent leaks, revealing the identities of key personnel, financial structures, and thousands of compromised systems worldwide. These leaks detail how the group uses spear-phishing, fake login pages, and malicious attachments to gain initial access, followed by persistent surveillance and data exfiltration from government, academic, and civil society networks. Technical analysis of these groups' operations highlights the use of legitimate system tools for lateral movement and persistence, as well as complex command-and-control (C2) infrastructures designed to evade detection. The leaks concerning Charming Kitten provide unprecedented insight into the operational management and financial underpinnings of Iranian cyber espionage, including the use of front companies and detailed tasking sheets. Both APT15 and APT35 demonstrate the ongoing evolution of state-sponsored cyber threats, with a focus on stealth, persistence, and the targeting of sensitive information across multiple sectors and geographies.
