A new ransomware group is emerging on the darkweb, looking for affiliates to start its operations. This group calls itself BlackMatter and has posted ads on two cybercrime forums named Exploit[.]in, and XSS[.]is. The BlackMatter ransomware group is seeking cybercriminals already having access to the potential target’s networks. In RaaS, the ransomware group creates ransomware and a platform to manage the possible targets and victims.
|Target||Firms with revenue of $100 Million and|
|Affected Region||United States of America, Canada, Australia, and Great Britain.|
|Threat Description||New ransomware group looking for affiliates for ransomware operations.|
Cyble Research Labs found the post on XSS[.]is by the threat actor named BlackMatter, as shown in Figure 1. In the post, the TA has mentioned the conditions required for affiliates to join them, which are as follows:
- Corporate Networks should be from one of the following countries: the United States of America, Canada, Australia, and Great Britain.
- They are targeting all organizations except the medical industry and government institutions.
- The revenue of the target organization should be more than $100 million and should be having 500-1500 hosts.
- The networks on which other actors have already tried attacks are excluded from the target list.
The TA has given two options for affiliation. The first option offers to buy network access for an amount ranging from $3k to $100k. In the second option, affiliates may work with the group in place of a percentage in ransom. Once the affiliates are selected, they need to deposit $120,000 to the group to participate in their ransomware activity.
The TA has posted a similar threat post on another cybercrime forum named Exploit[.]in. The TA post is shown in Figure 2.
We found that the leak website of the BlackMatter ransomware group is hosted in the TOR network (Figure 3). The Home page shows buttons for media updates and contact. The Home page displays the message, “All blogs hidden for now. For a very short time.” It indicates that the group has started its operations.
When we clicked on the button for media updates, we were redirected to the Media page, as shown in Figure 4. It also displays information such as excluded targets and messages to the media. Following is the list of excluded targets:
- Critical infrastructure facilities (nuclear power plants, power plants, water treatment facilities).
- Oil and gas industry (pipelines, oil refineries).
- Defense industry.
- Non-profit companies.
- Government sector.
Referring to the above list, we can say that the ransomware group is targeting private organizations so that they can continue their operations without getting media attention. We can imply that attackers are aware of the consequences of compromising highly sensitive targets. Based on rules and about us information given on the BlackMatter ransomware leak website, we suspect that this group has close connections with the DarkSide ransomware group. We presume that the group is only interested in the money.
Figure 4 shows the contact page of the BlackMatter Ransomware through which people can contact the ransomware group.
The BlackMatter ransomware group tries to gain access to critical servers from other threat actors in order to launch its campaign. Organizations should perform security scanning and immediate patching of known vulnerabilities using various processes such as Vulnerability Assessment and Penetration Testing (VAPT), Red teaming, and Purple teaming.
Cyble Research Labs is continuously monitoring BlackMatter activities. We will keep informing our clients with recent updates about this campaign.
- Use strong passwords and enforce multi-factor authentication wherever possible.
- Turn on the automatic software update feature on your computer, mobile, and other connected devices wherever possible and pragmatic.
- Use a reputed anti-virus and internet security software package on your connected devices, including PC, laptop, and mobile.
- Refrain from opening untrusted links and email attachments without verifying their authenticity.
