Prepared by: David Brunsdon, Threat Intelligence - Security Engineer, HYAS

I read this article the other day from Hacker News about a DNS-based malware campaign that used fake IP scanners in the industry-news channel. I spent some time looking into it in the HYAS Insight threat intelligence and investigation platform.

I was able to uncover the registration details, which led to a google cloud IP that was operating C2 from their email, and then to a potential actor IP in Nigeria. This led me to more exploration, and I am nowhere near done with it, so stay tuned on this!

This week, we saw a surge in activity related to the Risepro malware, particularly targeting IP address ((( - its C2 “mother ship.” This signifies a concerning development in the cyber threat landscape, as Risepro, akin to StealC, is a notorious form of stealer malware designed to exfiltrate sensitive information from compromised systems.

This threat analysis aims to provide an in-depth understanding of the Risepro malware campaign based on the provided information, focusing on the actor's tactics, techniques, and procedures (TTPs). Read on to learn what we found.

Technical Analysis:

Malware Communication:
The malware communicates with its command-and-control (C2) server located at (((( This indicates an established infrastructure for remote control and data exfiltration. The use of non-standard HTTP ports, may suggest an attempt to evade detection by hosting on a non-standard HTTP port.


Actor Details:

  • Actor IP: (((( (France)
  • Actor Device User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64)
  • AppleWebKit/537.36 (KHTML, like Gecko) Chrome/ Safari/537.36
  • The actor's location in France indicates potential attribution, although it's important to note that threat actors often utilize proxy servers or compromised systems to obfuscate their true origin.

HYAS Insight Analysis:
HYAS Insight threat intelligence and investigation platform provided valuable intelligence regarding the actor's IP and user agent when accessing the C2 interface. This information can aid in tracking and potentially attributing the actor behind the Risepro campaign and can help security teams determine whether their organization is a target.

Risk Assessment:

Data Compromise:
Risepro malware specializes in stealing sensitive data, including credentials, financial information, and personal identifiers. The compromised data can be monetized through various means, including sale on underground forums or exploitation for fraudulent activities.

Operational Disruption:
The infiltration of Risepro malware into organizational networks can lead to operational disruptions, including system slowdowns, service outages, and loss of critical data. This can result in financial losses and damage to reputation.

Intellectual Property Theft:
Organizations storing proprietary information are at risk of intellectual property theft. Risepro malware can exfiltrate intellectual property, trade secrets, and other confidential data, leading to competitive disadvantages and loss of market position.

Mitigation Strategies:

Network Monitoring:

  • Implement robust network monitoring solutions to detect and analyze suspicious network traffic, especially to known malicious IP addresses like (((
  • Utilize intrusion detection systems (IDS) and intrusion prevention systems (IPS) to identify and block malicious activities associated with Risepro malware.

Endpoint Protection:

  • Deploy advanced endpoint protection solutions capable of detecting and blocking malware, including fileless and polymorphic variants.
  • Conduct regular endpoint security assessments and ensure all systems are up-to-date with the latest security patches and updates.

Threat Intelligence Sharing:
