Their activities include phishing campaigns, ransomware attacks, and website defacements, often releasing partial evidence of success to bolster their reputation. Notable incidents include attacks on Israel's Iron Dome radar systems, a ransomware assault on Ma’agan Michael Kibbutz, and an alleged data breach of Zerto, a Hewlett Packard Enterprise subsidiary. The group utilizes sophisticated methods, including phishing links and attachments, to compromise and exfiltrate sensitive data. Handala is considered a serious cyber threat, primarily targeting Israel's critical sectors.

Peach Sandstorm, an Iranian threat actor, has conducted password spray attacks since February 2023 against global organizations, notably in the satellite, defense, and pharmaceutical sectors. These attacks originated from TOR IPs and employed a mix of public and custom tools like AzureHound and Roadtools for reconnaissance. Once inside the network, the group established persistence through mechanisms like Azure subscriptions and Azure Arc. They also attempted to exploit vulnerabilities in Zoho ManageEngine and Confluence. Some instances involved data exfiltration and lateral movement using techniques like Golden SAML and remote desktop protocol (RDP).

The Cybersecurity and Infrastructure Security Agency (CISA), FBI, and Cyber National Mission Force (CNMF) identified multiple APT actors exploiting vulnerabilities in an Aeronautical Sector organization as early as January 2023. The actors targeted a public-facing application (Zoho ManageEngine ServiceDesk Plus) and the organization’s firewall device, exploiting CVE-2022-47966 and CVE-2022-42475. They gained unauthorized access, established persistence, moved laterally, and engaged in defense evasion by deleting logs. Although the attackers achieved extensive network enumeration and credential access, the report didn't confirm any data exfiltration.

In April 2022, CISA detected Iranian government-sponsored APT activity compromising an FCEB organization's network via the Log4Shell vulnerability. Initial exploitation targeted an unpatched VMware Horizon server, later spreading to the domain controller. The threat actors utilized PowerShell commands, disabled Windows Defender, and established persistence through scheduled tasks. Tools like Mimikatz and Ngrok were deployed for credential harvesting and C2 communication. Despite attempts to dump the LSASS process, additional anti-virus measures thwarted this activity. Lateral movement was observed, as were activities aimed at credential and account manipulation.

POLONIUM, suspected to be coordinating with Iran's Ministry of Intelligence and Security, is actively targeting Israeli organizations across multiple sectors such as critical manufacturing, IT, and defense. The group exploits supply chain vulnerabilities by compromising IT companies to further target downstream organizations like aviation companies and law firms. TTPs include custom implants like CreepyDrive that use cloud services for C2 and data exfiltration. MSTIC also notes overlap with Iranian groups MERCURY, CopyKittens, both in targeted victims and techniques like using AirVPN and OneDrive. Though unconfirmed, around 80% of victims were observed running Fortinet appliances, suggesting a potential CVE-2018-13379 exploitation.

The Iranian APT group Moses Staff deployed a new, previously undocumented Remote Access Trojan (RAT) called StrifeWater for its cyber-espionage and disruption operations. The StrifeWater RAT has been used in initial attack stages, demonstrating various capabilities like listing system files, executing system commands, creating persistence, and downloading updates. Post-infection, it's replaced with ransomware not for financial gain but to disrupt operations and inflict system damage. Victims of these attacks span globally across countries like Israel, Italy, India, Germany, Chile, Turkey, UAE, and the US.

Some Iranian government-sponsored APT groups have exploited vulnerabilities in Microsoft Exchange servers and Fortinet devices since March 2021. These actors broadly targeted critical infrastructure sectors in the US, including Transportation and Healthcare and Public Health, as well as Australian organizations. The APT group focused more on exploiting known vulnerabilities rather than specific sectors, using the gained access for ransomware deployment, data exfiltration, and extortion. Several tactics, techniques, and tools were utilized, including creating new user accounts and modifying Task Scheduler.

The Iranian APT group MalKamak has been targeting aerospace and telecommunications companies in the Middle East since at least 2018, with additional victims in the US, Russia and Europe. The group uses ShellClient, a newly discovered remote access trojan (RAT), to conduct highly targeted cyberattacks. ShellClient uses Dropbox, a popular cloud-based service, for command and control (C2) operations, replacing the group's previous C2 infrastructure.

Operation GhostShell is a cyber espionage campaign targeting aerospace and telecommunications companies, primarily in the Middle East, with victims in the U.S., Russia and Europe. The operation, carried out by the Iranian group MalKamak, uses a stealthy, evolving remote access trojan (RAT) called ShellClient, which has been in development since 2018. ShellClient evades detection through masquerading, AES encryption and WMI-based reconnaissance. The attackers used tools such as PAExec for lateral movement and lsa.exe for credential dumping. Data exfiltration was facilitated by using WinRar to compress stolen information before sending it via Dropbox.

Iranian APT33 has been detected running a phishing campaign that employs fake job scams to lure victims. The campaign aims for credential theft, information theft, and unauthorized remote access.

A Saudi Arabian Government entity has been targeted by an innovative attack that relies on macros within malicious Word documents and leverages various scripts rather than a binary payload. The attack uses a VBScript to lower security settings within Microsoft Word and Excel and fetches data from Pastebin. A PowerShell script then communicates with the C2 server and exfiltrates data, persistently remaining undetected and continuing to collect information from the targeted system. The primary targeted sector is the Government.

The Iranian threat agent CopyKittens compromised multiple Israeli websites, including the Jerusalem Post, and one Palestinian Authority website between October 2016 and January 2017. The attackers bought access to the server to gain the access, inserting a single line of Javascript into existing libraries. This enabled them to load further malicious Javascript from a domain they controlled, selectively targeting users based on their IP addresses. The malicious payload used was the BeEF Browser Exploitation Framework.

CopyKitten, a known cyber-attack group, has launched a spearphishing campaign targeting the Israeli government’s Ministry of Communications. The investigation commenced with the identification of a suspicious domain that led to multiple related domains.
