An infection with Arcus Media, like any ransomware, results in your systems being locked and your data encrypted. Victims are then presented with a ransom demand, often in cryptocurrency, to restore access and prevent stolen data from being leaked online.
If you discover a physical break-in at your offices, your first thought would be to call the police; touch nothing and let them search for clues to the perpetrator. Then, work out how to get your business operations back up and running.
A cyber-attack requires the same logic. Your environment is a CRIME SCENE. It's imperative for the environment to remain untouched so that a forensic investigation can be carried out.
This is not a job for your IT team or MSP. There are digital forensic specialists available 24/7 who can assist you, just like in a physical crime.
First detected in early 2024, Arcus Media is a sophisticated ransomware operation known for its highly targeted attacks and ability to bypass traditional security measures. While its origins remain uncertain, cyber analysts have noted similarities between Arcus Media and previous high-profile ransomware groups, indicating it may be an evolution of an existing threat actor.
Arcus Media primarily targets Windows-based enterprise environments, leveraging phishing emails, compromised remote desktop protocol (RDP) access, and software vulnerabilities to infiltrate networks. Once inside, the ransomware spreads laterally, encrypting files and exfiltrating sensitive data. Victims are then pressured to pay a ransom under the threat of public data exposure.
Arcus Media employs a double extortion strategy, encrypting files while also exfiltrating sensitive business and personal data. This tactic forces victims to consider not only system recovery but also the potential fallout from having their confidential information published on dark web forums or sold to other cybercriminals.
Once deployed, the ransomware encrypts critical data and disables security software to hinder recovery efforts. Victims receive a ransom note demanding payment in cryptocurrency, with a deadline to prevent data leaks. In some cases, Arcus Media has also been observed using distributed denial-of-service (DDoS) attacks as an additional pressure tactic.
Given its advanced tactics and swift adoption of new exploitation techniques, Arcus Media poses a significant risk to organisations worldwide. Cybersecurity experts continue to track its activities, urging businesses to implement robust security measures to defend against this evolving ransomware threat.
Emerging in early 2024, Arcus Media is a relatively new yet rapidly expanding ransomware threat. Security reports indicate that within its first few months, the group has already claimed dozens of victims, with attacks targeting sectors such as finance, healthcare, and government agencies.
To date they have successfully claimed 71 victims.

A forensic analysis needs to be meticulous and a clean restore and recovery requires a wealth of experience not normally available in an in-house team who must provide a broader range of IT support skills:
Solace Cyber was established precisely for this scenario. We have a well-defined process for handling cyber-attacks like Arcus Media, which involves a 6-step approach:
It includes a thorough digital forensic analysis from step 2 where the output becomes a central component of business recovery. This is because understanding the attack is of critical importance:
It is critical that the analysis of digital evidence is carried out to an agreed plan. This will have been designed to provide the best and earliest chance of discovering a root cause, which is essential to inform remediation/eradication and recovery as well as supporting a legal take-down case if this is applicable. A legal take-down means we can assist in the legal enforcement that stops the criminals from publishing the data, thus undermining the ransom notice.
Solace’s Digital Forensic and Incident Response teams maintain consistent communication throughout. Dedicated Incident Managers and technical engineering leads provide updates during the Cyber Incident Response journey, utilising risk registers and working within change management processes, all from triage through to post-incident, delivering successful business recovery.
Solace Cybers’ support continues beyond the recovery process. Once your business is back up and running, we work with you to transform your cyber security through a threat-informed approach utilising our 9-step approach Solace Global - Cyber 9 Step Process.
The Arcus Media ransomware entered your system by one of several ways:
We recommend you adopt policies to:
After recovering from Arcus Media, Solace Cyber recommends that you update your business continuity plan to account for lessons learnt during this attack & recovery.
Most ransomware breaches cost approx £500K with smaller email data breaches in the realm of £50K. There is a dichotomy of preserving the environment for forensics or recovering it quickly for less business interruption. The cost increases the longer it takes to identify the breach and resolve it.
A Cyber Security insurance claim is complex and includes reasonable expenses to investigate and remediate an incident along with cover for legal, business interruption, criminal liability, employment liability and ransom policies. The insurance industry is liable to deliver the business recovery BUT Cyber insurance is viewed as volatile within the industry and many insurance policies are not being validated correctly.
Navigating through this requires experience, which is where Solace Cyber can help.
Facing genuine pressure, there's a crucial decision to make - one that could rescue your organisation from weeks of operational standstill, reputation damage, and client data loss. Yet, the probability of a favourable outcome remains slim, emphasising the importance of engaging a specialised ransomware incident response team. They are your most viable recourse for navigating a ransomware incident.

Almost certainly, yes. It is possible that some of the data lost is classified as “Personal Data” to your customer. You have a legal obligation to protect that data but it may have been lost. You may also need to advise the Information Commissioner's Office (ICO) at https://ico.org.uk/.
Your insurer/legal council will advise you on what to do and how to proceed with this.
Solace has experience working with insurers and lawyers and can help in this relationship at this stressful time.
A ransomware attack poses the biggest threat to your business by:
If you have a business interruption, how do you know where you are in your supply chain for any one item and how do you carry on with your business? If it persists for a long time, how do you maintain your operation? And when your systems and data are restored, how do you backfill with any work you did and how do you operate going forward?
Ransomware is second only to receivership for debilitating a business.
