A new cyber-espionage campaign, bearing similarities to the earlier MuddyWater attacks, is targeting government organizations and telecommunication companies in Turkey, Pakistan, and Tajikistan. The campaign uses spear-phishing tactics with malicious documents, leveraging social engineering to trick victims into enabling macros and activating payloads. Visual Basic and PowerShell scripts are used, with obfuscation techniques employed to evade detection. The attackers also use persistence methods and engage in system owner/user discovery, collecting system information and taking screenshots before sending this data to a command-and-control server.

The Iran-based attack group, Chafer, escalated operations in 2017, striking more organizations within and beyond the Middle East. Utilizing several new tools, they targeted sectors including airlines, telecoms services, and IT services for transport sectors among others. Chafer sought to infiltrate a major telecoms services provider and an international travel reservations firm, likely aiming for widespread surveillance. The group employed malicious documents, SQL injection attacks, and newly adopted open-source tools to compromise targets. These activities indicate a growing threat, especially as Chafer shows a rising trend in attacks on supply chains.

The Flying Kitten group conducted extensive espionage and surveillance campaigns from 2013 to 2014. Utilizing spearphishing, social engineering, and the "Stealer" malware, they targeted high-profile individuals, security researchers, and various sectors. The campaigns involved compromised social media accounts and phishing domains to gather credentials and sensitive information. The malware recorded keystrokes, took screenshots, and collected system data, focusing on credential harvesting rather than file exfiltration. This activity impacted targets in the United States, Israel, and global academia and business sectors.

Unit 42 monitored OilRig's testing of the TwoFace webshell, specifically its TwoFace++ variant, to evade detection by security tools. Analysis revealed that OilRig's developers systematically modified the webshell's loader script to reduce detection rates, ultimately achieving zero detection by altering code related to the embedded payload's update functionality. The testing involved decoding and encrypting webshell data and frequent code alterations to pinpoint and circumvent security measures. Additionally, another webshell, named DarkSeaGreenShell, was discovered during these tests.

The Iranian cyber groups Flying Kitten and Rocket Kitten exhibited overlapping tactics in credential theft and spearphishing, targeting entities in sectors like media, education, and technology across the UK, US, and Iran. Utilizing domains that mimicked legitimate services, such as Google and Microsoft, they orchestrated phishing campaigns to harvest user credentials. Their operations involved shared phishing toolkits and malware, including a keylogger, with connections back to Iranian infrastructure. Despite cessation of Flying Kitten activities post-2014, their tools and tactics were resurrected by Rocket Kitten, highlighting the persistent threat posed by these actors.

The research team at Palo Alto Networks has discovered a group of targeted cyber-attacks against the Middle East region that occurred between February and October 2017, carried out by "MuddyWater". These attacks are espionage-related. The group used a PowerShell-based first-stage backdoor called "POWERSTATS", which evolved slowly over time, and targeted countries including the USA and India, as well as those within the Middle East like Saudi Arabia, Iraq, Israel, and the United Arab Emirates. The group also used GitHub to host its backdoor.

MuddyWater group continues its cyber-espionage operations, leveraging obfuscated PowerShell scripts within Word documents to infiltrate systems. These documents masquerade as legitimate entities, such as the Federal Investigation Agency of Pakistan. The tactics include sophisticated obfuscation techniques and a careful reconnaissance strategy, primarily focusing on the Middle East and Pakistan. The campaign deploys a variety of tools, including C&C servers and proxies, with a detailed focus on avoiding detection by analysis tools.

The OilRig threat group has been utilizing a refined version of the Clayslide delivery document for spear-phishing attacks since May 2016. Recently, they have developed a new custom Trojan named "ALMA Communicator", and incorporated the use of Mimikatz for credential harvesting in the delivery phase of the attack. The targets included an individual at a public utilities company in the Middle East. ALMA Communicator uses DNS tunneling for C2 communication and has some data transfer limitations, which may have prompted the early deployment of Mimikatz.

The Iranian threat agent Greenbug registered domains similar to Israeli high-tech and cybersecurity companies, as well as a Saudi Arabian electrical equipment firm. A sample of the ISMdoor malware was submitted from Iraq on October 15, 2017, indicating the threat actor's activities. Despite these registrations, no evidence of direct targeting or impact on these companies is present. High-tech, cybersecurity, online advertising, airport security systems, web development, behavioral biometrics, artificial intelligence, data security, and autonomous driving are sectors potentially of interest to the actor.

Entities in the Middle East, including Saudi Arabia and Iraq, were targeted by an early MuddyWater phishing campaign predominantly aimed at the government sector. Spear-phishing emails carrying malicious attachments were a key tactic, with PowerShell scripts being sourced from Pastebin and Filebin. To avoid detection, the attackers concealed their scripts. Upon examining the macro code and command and control scripts, parallels were found with a campaign previously discussed by Morphisec.

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.

Unit 42 uncovered the TwoFace webshell, a sophisticated dual-component tool used by attackers for prolonged unauthorized access within a Middle Eastern organization's network. The TwoFace webshell enabled execution of various commands and facilitated lateral movement by copying itself across servers. The intruders utilized Mimikatz to harvest credentials and orchestrated their attacks from multiple international IP addresses, suggesting a broad geographic operational footprint. Analysis revealed that the attackers maintained access since at least June 2016, using obfuscated C# code on ASP.NET servers to remain undetected and manage the webshell payload.

The article "The Curious Case of Mia Ash" by SecureWorks details a sophisticated cyber espionage campaign. This campaign involved a fake online persona named Mia Ash, created by the threat group COBALT GYPSY, which is associated with Iranian cyber operations. Mia Ash was used to establish relationships with employees in targeted organizations, primarily in the Middle East and North Africa. The persona, active across various social media platforms, was instrumental in delivering malware through seemingly innocent interactions. The case underlines the increasing complexity of cyber threats where social engineering and fake identities are employed to breach security systems.

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. One such domain closely mimicked the Israeli Prime Minister's SSL VPN login page and was used to drop a malicious Word document titled "Annual Survey.docx." This document had an embedded OLE object that communicated with a C2 server, signifying a well-planned attack. The campaign appears to be part of CopyKitten's ongoing activities against Israeli interests.

Beginning in late 2016, Shamoon 2.0 and the newly discovered StoneDrill malware launched destructive wiper attacks against critical and economic sectors in Saudi Arabia, with evidence of StoneDrill reaching European targets. Shamoon 2.0, a successor to the 2012 Saudi Aramco attack tool, incorporated stolen administrator credentials, automated worm-like spreading, disk wiping, and even inactive ransomware capabilities. StoneDrill introduced advanced sandbox evasion, injected its payload into browsers, and targeted accessible files or full disks. Both malware families used obfuscation, anti-analysis tricks, and in Shamoon’s case, signed drivers for low-level destruction. StoneDrill shared code similarities with the NewsBeef (aka Charming Kitten) APT, suggesting broader regional targeting and actor overlap.

The BlackBerry Cylance threat research team's report offers a comprehensive analysis of the Disttrack malware, also known as Shamoon, renowned for its devastating attacks on system master boot records. The report traces the malware's history, its resurgence, and explores its technical operations, including network management capabilities and modular architecture. It particularly highlights Disttrack's impact on Saudi Arabia's critical infrastructure, demonstrating its potential for significant damage. This abstract succinctly captures the essence of the malware's threat and operational dynamics for a general audience.

The report details the Magic Hound cyber campaign targeting primarily Saudi Arabia. The campaign leveraged spearphishing emails with malicious attachments and links, PowerShell scripts, Windows Command Shell, and obfuscation techniques like XOR and Base64 encoding. Additionally, the attackers utilized HTTP and HTTPS protocols for command and control communication.

SecureWorks researchers identified a phishing campaign targeting a Middle Eastern organization in January 2017, linked to COBALT GYPSY (Aka OilRig). The attackers employed spear-phishing emails containing shortened URLs redirecting to spoofed domains. Victims were presented with a malicious Microsoft Office document, which executed PowerShell commands when opened, installing PupyRAT, a multi-platform remote access trojan (RAT).

The MacDownloader malware, initially observed targeting the defense industrial base and a human rights advocate, impersonates legitimate software like Adobe Flash Player and Bitdefender Adware Removal Tool to steal system information and macOS Keychain data. It reflects initial development efforts by possibly amateur Iranian-affiliated actors and is linked to previously documented Iranian operations targeting aerospace and defense employees. The malware, which also gathers user credentials, lacks effective persistence features and uses similar infrastructure as previous campaigns attributed to the Iranian group Charming Kitten.

In mid-November 2016, Mandiant responded to the Shamoon 2.0 malware attack targeting organizations in the Gulf states, marking the return of the suspected Iranian hacker group "Cutting Sword of Justice." This updated version of the 2012 Shamoon malware features embedded credentials, suggesting previous targeted intrusions for credential harvesting. Shamoon 2.0 performs subnet scanning, uses domain-specific credentials for unauthorized access, modifies system registries, and schedules tasks for execution. Its payload involves overwriting system files and wiping boot records, notably shifting imagery from a burning U.S. flag to a photograph of Alan Kurdi, symbolizing a devastating critique through cyber vandalism.

The OilRig cyberattack campaign, first analyzed in May 2016, continues to evolve, targeting government organizations and companies in Saudi Arabia, Qatar, Turkey, Israel, and the United States. Using spear-phishing emails with malicious Microsoft Excel documents, the attackers have updated their toolset, including Clayslide delivery documents and the Helminth backdoor. The malware communicates with remote servers via HTTP and DNS for command and control. Despite its lack of sophistication, the malware successfully operates under the radar in many establishments due to techniques like DNS command and control.

In early 2016, the NewsBeef APT (aka Charming Kitten/Newscaster) repurposed the open-source BeEF and Metasploit frameworks in widespread watering hole attacks. These operations targeted visitors to strategically compromised websites, including institutions in Iran, Russia, India, Ukraine, the EU, Turkey, Germany, Japan, China, Brazil, and more. Sectors impacted included education, military, diplomacy, manufacturing, and media. The attackers injected malicious JavaScript to hook browsers, track visitor behavior, and fingerprint systems using evercookies and browser enumeration. While full exploitation wasn’t always observed, selective delivery of backdoors or spoofed login prompts was reported. The group’s campaign reflects an evolution from low-tech social engineering to more technically advanced infrastructure attacks using open-source tools.
