Executive Summary
The ransomware group RA Group, now known as RA World, showed a noticeable uptick in their activity since March 2024. About 37% of all posts on their dark web leak site have appeared since March, suggesting this is an emerging group to watch. This article describes the tactics, techniques and procedures (TTPs) used by RA World.
RA World uses a multi-extortion scheme, which usually includes exfiltrating sensitive data from its victims prior to encrypting it. The ransomware operators then use the exfiltrated data as leverage, threatening to post it on their website in case victims do not meet their ransom demands.
RA World notably experimented with a “cost per customer” calculation. Below victim entries, they posted comments such as, “This company isn’t willing to pay $0.5 per customer to protect their privacy.”
Analysis of the posts on their leak site shows that RA World mainly impacted organizations in the healthcare industry until recently. The group did not appear to have any particular qualms about attacking organizations in a sensitive sector such as healthcare. Midway through 2024, manufacturing became the sector most impacted by the group. It is possible that the shift came from a desire to attack organizations more likely to be able to pay higher ransoms. However, many ransomware groups are simply opportunistic, and it is also possible the change was incidental.
The U.S. is the country most affected by these attacks, followed by countries in Europe and Southeast Asia.
Palo Alto Networks customers are better protected against the ransomware used by RA World through the following products and services:
- Cortex XDR and XSIAM
- Cloud-Delivered Security Services for the Next-Generation Firewall such as Advanced WildFire and Advanced URL Filtering
The Cortex XDR anti-ransomware module includes out-of-the-box protections that prevent adverse behavior from the ransomware samples we tested, without the need for specific detection logic or signatures.
The Prisma Cloud Defender should be deployed on cloud-based Windows virtual machines for better protection against the ransomware used by the RA World. Cortex Xpanse is able to provide visibility that can prove valuable for proactive protection.
The Unit 42 Incident Response team can also be engaged to help with a compromise or to provide a proactive assessment to lower your risk.

RA World Overview
Ever since Talos first described it in 2023, RA World has been steadily active. Out of the organizations it has publicly claimed to have breached, the largest number were in the manufacturing sector. Figure 1 below details the statistics of different sectors affected by the RA World. The data covers the period from mid-2023 to June 6, 2024.
![Bar chart showing counts of various industries with "Manufacturing" having the highest count and decreasing to "Agriculture" with the lowest. Industries labeled include Transportation and logistics, Wholesale and Retail, Insurance, Pharma and Life Sciences, Healthcare, Finance, Real Estate, Construction, Media and Entertainment, Government, Nonprofit, and Education.](https://unit42.paloaltonetworks.com/wp-content/uploads/2024/07/chart.png)
According to analysis of leak site data, RA World impacts organizations based in the U.S. the most. The group has also impacted organizations in several countries in Europe, such as Germany and France. In Asia, organizations in Taiwan were impacted. In addition, Trend Micro reported that the group recently carried out a campaign affecting organizations in South America.
When RA World renamed its gang from RA Group, they also changed their encrypted file extensions to .RAWLD. In addition, they changed the title and content of their ransom note to include their new name, as shown in Figure 2 below.

The note warns that failure to comply will result in the public release of sample data within three days and data will be released in batches in seven days. It includes terms for negotiating and references to additional unhappy victims' lists. The file is titled "Data breach warning.txt - Notepad."

Leak Site
RA World maintains a leak site, where the group uploads portions of the stolen data they exfiltrate from their victims to coerce ransom payments. Their website's design also looks upgraded compared to their old website's simple look that was shown in previous research in 2023. Figures 3 and 4 below show the two recent iterations of the leak site’s main page.
![The image displays a screenshot of a website titled "RA World." The website has a dark theme with a background image of a dimly lit corridor that gives a high-tech, eerie vibe. At the center of the webpage, there is a large banner with the text "Welcome to RA World" followed by a smaller subtext stating, "War is death's feast. I survived, but my friend didn't." The top navigation includes tabs such as Home and Victim List. The logo "RAW" in a bold style appears prominently.](https://unit42.paloaltonetworks.com/wp-content/uploads/2024/07/word-image-824939-135642-3.jpeg)
In the website’s most recent version, they display a famous line from the work of English poet John Donne, “for whom the bell tolls, it tolls for thee” on the main page. Threat actors also use this line as the string for the mutex in their final payload, the Babuk ransomware.
![Website for "RA World" with a dark, futuristic interface featuring neon blue and green lines on a grid layout. Heading at the top reads "Welcome to RA World" followed by a smaller caption "For whom the bell tolls, it tolls for thee."

Some of the information is redacted.](https://unit42.paloaltonetworks.com/wp-content/uploads/2024/07/word-image-827485-135642-4.jpeg)
Figure 5 shows the bottom portion of the group’s main page, which contains a link to an X (formerly Twitter) search. The right-hand side of the screenshot claims a “copyright” for the site under their new RA World name, but as of this writing, the X search link still points to the older search term, ragroup.
![Twitter logo on the left with a clickable URL link to a Twitter account on the right and the text "Copyright © RA World 2023" below.](https://unit42.paloaltonetworks.com/wp-content/uploads/2024/07/word-image-830030-135642-5.png)
X is considered a major platform for security vendors and researchers to share findings, so it would make sense for the threat actor to follow use of their name for publications about their activity.
Figure 6 shows a victim’s leak page from early 2024 where RA World attempted to publicly damage the victim’s reputation by stating what they allege is the real “cost per customer.” They arrive at this figure by taking the total requested ransom amount divided by the number of the victim’s customers, if the victim is a customer-facing company. They frame this figure in terms of what the victim is unwilling to pay to “protect their customers’ privacy.”
![The image is a screenshot of RA World's website titled "RA World". Highlighted in a red rectangle is a section labeled "Type", containing the text, "This company isn't willing to pay $0.5 per customer to protect their privacy." There are additional tabs or sections labeled "Home" and "Victim" visible at the top of the image.](https://unit42.paloaltonetworks.com/wp-content/uploads/2024/07/word-image-832668-135642-6.png)
The threat actors updated the victim’s leak page in the leak site's recent version, as shown in Figure 7 below. They removed the “cost per customer” figure, but they added a “Coming soon….” section that displays new victims who will soon be listed. This section is most likely meant to include victims who were not willing to pay the ransom, and RA World is still in the process of uploading their exfiltrated data.
![The image depicts a futuristic-looking webpage titled "RA World" with a "Coming soon..." header. The sharp blue and black color scheme gives a cybernetic feel, with luminous lines and a dark background. It features a form titled "Target Introduction" with fields such as Name, Official Website, Size in GB, Content, Schedule for Document Public Release, Sample File Download Address, and a schedule area marked "To be determined".

Technical Analysis
We have mapped the attack stages using the MITRE ATT&CK framework to activities that are common to RA World.
Initial Access
Based on our telemetry, RA World predominantly exploits misconfigured or vulnerable internet-facing servers. We have not observed instances of phishing attacks to gain initial access to the environment.
Credentials Dumping
We observed the threat actor attempting to use the PsExec utility to dump credentials by executing another SysInternals tool, ProcDump. They also attempted to run the quser and tscon commands to retrieve data about the current user and remote session.
Figure 8 below shows Cortex XDR prevented these attempts.
![Flowchart diagram showing a process with two main branches, connected by various nodes and labels. Below is a navigation bar with multiple icons and text including "SOURCE," "SEVERITY," "ACTION" and more.](https://unit42.paloaltonetworks.com/wp-content/uploads/2024/07/word-image-838672-135642-8.jpeg)
Lateral Movement
To move laterally in the compromised network and execute commands on remote endpoints, RA World used the popular Impacket tool. They executed remote commands to dump the SAM hive, copied the NTDS database and exported the system registry.
The threat actor then used the makecab utility to archive the databases and deleted the previously extracted database files from disk. Table 1 below shows the commands and their descriptions.
Command | Description |
cmd.exe /Q /c copy \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy3\windows\NTDS\ntds.dit [redacted].dit 1> \\127.0.0.1\ADMIN$\__1706227818.9154336 2>&1 | Copying the NTDS database |

Persistence and Impact: A Multi-Stage Ransom Infection Chain
Germán Fernández, a security researcher from Chile, tweeted about various artifacts found in a ransomware attack by RA World earlier this year. The artifacts he mentioned include various executable files and scripts.
Trend Micro published the first public report of RA World’s updated tool set in early March 2024. Their analysis of the files revealed several stages, each having its own role in the infection process prior to the delivery of the final ransomware payload.
Stage 1: Loader
The initial loader, also known as Stage1.exe, has two main roles:
- Perform a variety of checks including assessing the domain name and looking for a file called Exclude.exe. Judging by its name, this file could contain exclusions such as specific machines and file paths.
- Add Stage2.exe to the SYSVOL shared path and then execute it.
The loaders are usually small files with a maximum size of about 10 KB. Figure 10 below shows most of the loader’s code.
![The image displays a computer screen showing a text editor with lines of code. The code involves domain controllers, accessing system paths, and executing a command on a Windows machine. Some of the information is redacted.](https://unit42.paloaltonetworks.com/wp-content/uploads/2024/07/word-image-844163-135642-10.jpeg)
Stage 2: Enable Safe Mode and Deliver Babuk
The next stage of the infection chain has two separate operation mechanisms that are dependent on whether or not the system is running in safe mode. Stage3.exe must be run in safe mode so it can evade detection by security solutions that, by default, won’t run in this mode. This file is the final ransomware payload, and a new Babuk variant.
If the system is operating in safe mode, the Babuk binary will be decrypted using Advanced Encryption Standard (AES) and then executed, followed by an attempt to disable safe boot. The AES key and initiation vector are generated based on the victim’s local domain name, which the malware would previously have retrieved in Stage1.exe.
Otherwise, Stage2.exe will write itself as a service to the compromised machine, using the following command:
- reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\MSOfficeRunOncelsls" /t REG_SZ /d Service /f
Figure 11 shows the execution of Stage2.exe that Cortex XDR detected and prevented.

Some of the information is redacted.](https://unit42.paloaltonetworks.com/wp-content/uploads/2024/07/word-image-846657-135642-11.jpeg)
Stage 3: New Variant of the Babuk Final Payload
Since its discovery in mid-2023, RA World has used a customized version of the Babuk ransomware, which had its source code leaked in 2021. In its recent activity, RA World has updated their Babuk-based payload with some relatively minor changes. Changes in this variant include:
- Changing the mutex name from DoYouWantToHaveSexWithCuongDong to For whom the bell tolls, it tolls for thee
- Changing the ransom note filename from How To Restore Your Files.txt to Data breach warning.txt
- Modifying the note’s content accordingly
- Changing the encrypted file extension to .RAWLD from .GAGUP
- Stripping down the previous variant’s PDB path
- Creating the file C:\Windows\Help\Finish.exe to indicate the encryption process is finished
- Adding more filenames, paths, processes and service names to exclude during encryption
Figures 12 and 13 show Cortex XDR detecting and preventing the execution of RA World’s Babuk payload.

RA World’s TTP Similarities With BRONZE STARLIGHT: A Possible, Yet Unverified, Connection
During our research, we identified some connections in the forensic data found in our telemetry that, with a low-confidence attribution level, tie RA World with BRONZE STARLIGHT (aka Emperor Dragonfly). BRONZE STARLIGHT is a Chinese threat group that deploys different ransomware payloads.
Several of the TTPs we found overlapped with TTPs used by BRONZE STARLIGHT, as discussed by Sygnia in 2022.
- NPS tool use: During our research, we found that the attackers were using NPS, an open-source tool created by a Chinese developer. The tool’s latest release was back in 2021, and it’s mainly used by Chinese threat actors. According to Sygnia, BRONZE STARLIGHT previously used this tool.
The path that the NPS tool was operating from in this research shares similarities with BRONZE STARLIGHT’s chosen path conventions. Table 2 below presents these similarities.
These folders exist by default in the operating system, so this is not sufficient evidence by itself to connect the related activity to this group or another. However, we believe that it is not coincidental that two ransomware groups use this uncommon tool and choose to place it under a similar path on infected environments, using the update suffix for both files.
RA World | BRONZE STARLIGHT |
C:\Windows\Help\Windows\ContentStore\[redacted]_update.exe | C:\Windows\Help\mui\0409\WindowsUpdate.exe |
Table 2. File path and naming convention similarities between the NPS tool variants deployed by RA World and BRONZE STARLIGHT.
- Impacket use: RA World used the same Impacket modules that Sygnia’s report mentions, to facilitate reconnaissance and lateral movement.
- Babuk use: The latest final ransomware payload of both of the groups is based on Babuk’s leaked source code.
- VirusTotal submitter origin country: When pivoting through VirusTotal and searching for files containing the string C:\Windows\Help\Exclude.exe, we noticed that the same submitter hailing from Hong Kong uploaded multiple variants of the Stage1.exe loader.
Some variants’ code iterations look incomplete, and this strengthens our assumption that this might be the threat actor testing their arsenal for detection rates.
One variant included the two strings seen in Figure 14 below. These strings contained internal IP addresses, which did not exist in other samples. The presence of these strings also indicates that this is an early loader variant likely in a development phase.
![Text showing two URLs: "http://127 dot 0 dot 0 dot 1:8888/Stage2 dot exe" and "http://192 dot 168 dot 15 dot 13:8080" on a plain background.](https://unit42.paloaltonetworks.com/wp-content/uploads/2024/07/word-image-854687-135642-14.png)
All the submissions had only one distinct submitter. This submitter uploaded one sample after another with a few minutes in between, on July 3, 2023. Figure 15 below shows the submitter information.
![Screenshot showing data related to a file, including timestamps and locations. All recorded activities happen in Hong Kong on the same date and time, with the source marked as Stage1.exe and a web origin. There is one submitter and a total of one submission.](https://unit42.paloaltonetworks.com/wp-content/uploads/2024/07/word-image-856885-135642-15.png)
- The threat actor’s operating time zone: Analyzing our telemetry, we noticed that threat actors executed the vast majority of reconnaissance and lateral movement-related commands on infected devices during office hours of the GMT +7 to GMT +9 time-zones.
- Misspellings in the code: While looking at the code of the different malware, we saw that logs by the author had clear mistakes in their use of English. Although it does not indicate a specific geographical location of an author, combining this finding together with other aforementioned points indicates that the threat developers are likely not native English speakers.Figures 16 and 17 below show examples of misspellings.
![Code snippet in C# showing a conditional statement that prints "Is runing!" and exits the environment if a flag is true. There is a spelling error in the word "running.](https://unit42.paloaltonetworks.com/wp-content/uploads/2024/07/word-image-859023-135642-16.png)
![This image displays a snippet of computer code in a dark-themed text editor. The code is written in C# and is part of an exception handling block that catches exceptions. When an exception occurs, the first line within the catch block logs the message "----Try to restart by SafeMode Failed----" (except that failed is misspelled) to a log file using a method named "SaveLog". The second line logs the exception details using the same "SaveLog" method. The code features syntax highlighting with keywords in blue, strings in red, and comments in green.](https://unit42.paloaltonetworks.com/wp-content/uploads/2024/07/word-image-861416-135642-17.png)
However, it is important to note that there could be other explanations for the connections described here. For example, other threat actors might coincidentally use Babuk or some of the same open source tooling, and threat actors from other countries might be prone to the same types of misspellings. Therefore, while the possible ties to BRONZE STARLIGHT bring up intriguing possibilities, we assess the connection with low confidence at this time.
Conclusion
In this article, we reviewed the latest developments in the operation of RA World that has recently rebranded itself from RA Group. We described evolutions in both their leak site and their operational tools. They used two different loaders to deliver their final payload, which was a new variant of the Babuk ransomware.
The RA World group remains steadily active, and they primarily affect the manufacturing sector according to their public leak site data.
Protections and Mitigations
Palo Alto Networks customers are better protected from the different TTPs used by RA World.
The Cortex XDR and XSIAM platforms detect and prevent the execution flows described in the screenshots included in the previous sections. Cortex Xpanse is able to provide visibility that can prove valuable for proactive protection.
The Cortex XDR agent included out of the box protections that prevented adverse behavior from the samples we tested from this group, without the need for specific detection logic or signatures.
Cortex XDR and XSIAM detect user- and credential-based threats by analyzing user activity from multiple data sources including the following:
- Endpoints
- Network firewalls
- Active Directory
- Identity and access management solutions
- Cloud workloads
Cortex XDR and XSIAM build behavioral profiles of user activity over time with machine learning. By comparing new activity to past activity, peer activity and the expected behavior of the entity, Cortex XDR and XSIAM detect anomalous activity indicative of credential-based attacks.
They are also designed offer the following protections related to the attacks discussed in this post:
- Preventing the execution of known malicious malware
- Preventing execution of unknown malware using Behavioral Threat Prevention and machine learning based on the Local Analysis module
- Protecting against credential-gathering tools and techniques using the Credential Gathering Protection, available from Cortex XDR 3.4
- Protecting against exploitation of different vulnerabilities including ProxyShell using the Anti-Exploitation modules as well as Behavioral Threat Protection
Cortex XDR is designed to detect post-exploitation activity, including credential-based attacks, with behavioral analytics.
The Prisma Cloud Defender as well as Cortex XDR for cloud agents should be deployed on cloud-based Windows virtual machines to ensure they are protected from these known malicious binaries. Advanced WildFire signatures can be used by both Palo Alto Networks cloud services to ensure cloud-based Windows virtual machine runtime operations are being analyzed and those resources are protected.
Cloud-Delivered Security Services for the Next-Generation Firewall such as Advanced WildFire and Advanced URL Filtering include protections based on the IoCs shared in this article.
