Vendor notification. To prevent exploitation attempts, organizations are highly recommended to install updates released by Microsoft. We are sharing this blog today so that others in the community can also be aware of the latest techniques we have observed being used by Iranian actors. Microsoft uses DEV- designations as a temporary name given to an unknown, emerging, or a developing cluster of threat activity, allowing MSTIC to track it as a unique set of information until we reach a high confidence about the origin or identity of the actor behind the activity.

Once it meets the criteria, a DEV is converted to a named actor. These ransomware deployments were launched in waves every six to eight weeks on average. This vulnerability allowed the attackers to collect clear-text credentials from the sessions file on vulnerable Fortinet VPN appliances.

This file would beacon periodically to their C2 servers via SSH, allowing the actors to issue further commands. Later, the actors would download a custom implant via a Baseencoded PowerShell command. This implant established persistence on the victim system by modifying startup registry keys and ultimately functioned as a loader to download additional tools.

BitLocker is a full volume encryption feature meant to be used for legitimate purposes. After compromising the initial server through vulnerable VPN or Exchange Server , the actors moved laterally to a different system on the victim network to gain access to higher value resources.

From there, they deployed a script to encrypt the drives on multiple systems. Victims were instructed to reach out to a specific Telegram page to pay for the decryption key. The attackers continue with several back-and-forth conversations discussing the questions with the target user before finally sending a meeting invite with a link masquerading as a Google Meeting.

The attackers contact the targeted user multiple times per day, continuously pestering them to click the link. The attackers even go so far as to offer to call the target user to walk them through clicking the link. The attackers are more than willing to troubleshoot any issues the user has signing into the fake Google Meeting link, which leads to a credential harvesting page.

Instead of phishing emails, CURIUM actors leverage a network of fictitious social media accounts to build trust with targets and deliver malware. The attackers build a relationship with target users over time by having constant and continuous communications which allows them to build trust and confidence with the target. In many of the cases we have observed, the targets genuinely believed that they were making a human connection and not interacting with a threat actor operating from Iran.

Further activity has targeted customers in geographic information systems GIS , spatial analytics, regional ports of entry in the Persian Gulf, and several maritime and cargo transportation companies with a business focus in the Middle East. MSTIC assesses that these observed overlapping activities suggest a coordination between different Iranian actors pursuing common objectives.

Microsoft will continue to monitor all this activity by Iranian actors and implement protections for our customers. Part 2 provides a deep dive on the attacker behavior and outlines investigation guidance. Today, beyond using resources for its traditional bot and mining activities, LemonDuck steals credentials, removes security controls, spreads via emails, moves laterally, and ultimately drops more tools for human-operated activity.

After installation, LemonDuck can generally be identified by a predictable series of automated activities, followed by beacon check-in and monetization behaviors, and then, in some environments, human-operated actions. These include general and automatic behavior, as well as human-operated actions.

We also provide guidance for investigating LemonDuck attacks, as well as mitigation recommendations for strengthening defenses against these attacks. These activities always result in more invasive secondary malware being delivered in tandem with persistent access being maintained through backdoors. These human-operated activities result in greater impact than standard infections.

Attackers then used this access to launch additional attacks while also deploying automatic LemonDuck components and malware. They did so while maintaining full access to compromised devices and limiting other actors from abusing the same Exchange vulnerabilities. This allows them to limit visibility of the attack to SOC analysts within an organization who might be prioritizing unpatched devices for investigation, or who would overlook devices that do not have a high volume of malware present.

Fileless techniques, which include persistence via registry, scheduled tasks, WMI, and startup folder, remove the need for stable malware presence in the filesystem. These techniques also include utilizing process injection and in-memory execution, which can make removal non-trivial.

It is therefore imperative that organizations that were vulnerable in the past also direct action to investigate exactly how patching occurred, and whether malicious activity persists.

However, many free or easily available RATs and Trojans are now routinely utilizing process injection and in-memory execution to circumvent easy removal. This behavior could change over time, as the purpose of this. After this, the next few actions that the attackers take, including the scheduled task creation, as well as the individual components and scripts are generally the same.

This script pulls its various components from the C2s at regular intervals. The script then checks to see if any portions of the malware were removed and re-enables them. They also have multiple scheduled tasks to try each site, as well as the WMI events in case other methods fail. This action could in effect disable Microsoft Defender for Endpoint, freeing the attacker to perform other actions.

These alerts can allow the quick isolation of devices where this behavior is observed. While this uninstallation behavior is common in other malware, when observed in conjunction with other LemonDuck TTPs, this behavior can help validate LemonDuck infections.

It also uses freely available exploits and functionality such as coin mining. Because of this, the order and the number of times the next few activities are run can change. This information is then added into the Windows Hosts file to avoid detection by static signatures.

In instances where this method is seen, there is a routine to update this once every 24 hours. It also renames and packages well-known tools such as XMRig and Mimikatz. BIN, M6. EXE, or M6G. LemonDuck uses this script at installation and then repeatedly thereafter to attempt to scan for ports and perform network reconnaissance. It then attempts to log onto adjacent devices to push the initial LemonDuck execution scripts. It then immediately contacts the C2 for downloads. A sample of ports that recent LemonDuck infections were observed querying include , , , , 22, , and This spreading functionality evaluates whether a compromised device has Outlook.

If so, it accesses the mailbox and scans for all available contacts. It sends the initiating infecting file as part of a. This script attempts to remove services, network connections, and other evidence from dozens of competitor malware via scheduled tasks.

It also closes well-known mining ports and removes popular mining services to preserve system resources. The script even removes the mining service it intends to use and simply reinstalls it afterward with its own configuration.

The older variants of the script were quite small in comparison, but they have since grown, with additional services added in and The attackers also patch the vulnerability they used to enter the network to prevent other attackers from gaining entry.

If unmonitored, this scenario could potentially lead to a situation where, if a system does not appear to be in an unpatched state, suspicious activity that occurred before patching could be ignored or thought to be unrelated to the vulnerability.

Below we list mitigation actions, detection information, and advanced hunting queries that Microsoft Defender customers can use to harden networks against threats from LemonDuck and other malware operations. Check the recommendations card for the deployment status of monitored mitigations. If you allow removable storage devices, you can minimize the risk by turning off autorun, enabling real-time antivirus protection, and blocking untrusted content.

Potentially unwanted applications PUA can negatively impact machine performance and employee productivity. In enterprise environments, PUA protection can stop adware, torrent downloaders, and coin miners. These capabilities use artificial intelligence and machine learning to quickly identify and stop new and unknown threats.

These alerts, however, can be triggered by unrelated threat activity and are not monitored in the status cards provided with this report. You can use the advanced hunting capability in Microsoft Defender and Microsoft Defender for Endpoint to surface activities associated with this threat. Additionally, checks if Attachments are present in the mailbox.

General attachment types to check for at present are. ZIP or. JS, though this could be subject to change as well as the subjects themselves. This query should be accompanied by additional surrounding logs showing successful downloads from component sites.

The exclusion additions will often succeed even if tamper protection is enabled due to the design of the application.

Custom alerts could be created in an environment for particular drive letters common in the environment. Options for more specific instances included to account for environments with potential false positives. Most general versions are intended to account for minor script or component changes such as changing to utilize non.

Bin, which is intended to kill competition prior to making the installation and persistence of the malware concrete. The killer script used is based off historical versions from and earlier, which has grown over time to include scheduled task and service names of various botnets, malware, and other competing services. The version currently in use by LemonDuck has approximately scheduled task names.

The upper maximum in this query can be modified and adjusted to include time bounding. The address is then attributed to a name that does not exist and is randomly generated. The script then instructs the machine to download data from the address. This query has a more general and more specific version, allowing the detection of this technique if other activity groups were to utilize it. Part 1 covers the evolution of the threat, how it spreads, and how it impacts organizations.

Spoofed email phishing scams can be hard for end users to identify. The scams involve sending a phishing email to a user and making the email appear as if it has been sent by a known individual. This could be a known contact such as a supplier, a work colleague, a friend or family member, or a well-known company. These phishing campaigns abuse trust in the sender and they are highly effective. Many end users are warned never to click on links in emails or open email attachments in messages from unknown senders, but when the sender is known, many users feel that the email is safe.
