MoneyMessage ransomware

Under attack by ransomware or suffering a cyber breach?

Speed is critical when facing a live cyber attack. If you believe you have been compromised by the MoneyMessage ransomware group or another threat actor, contact us immediately.

About MoneyMessage ransomware group

The MoneyMessage ransomware group has been active since at least 2021 and is known for conducting ransomware attacks against organisations across Europe and North America. The group operates a double extortion model, combining data encryption with threats to publish stolen information if ransom demands are not met.

MoneyMessage has targeted organisations in sectors such as manufacturing, logistics, and professional services. Its activity suggests a deliberate focus on businesses where operational disruption can quickly escalate commercial and reputational impact.

The group relies on established ransomware tooling rather than highly bespoke malware. Over time, MoneyMessage has continued to refine its techniques, contributing to its position as a persistent cyber threat rather than a short-lived campaign.

How MoneyMessage operators work

MoneyMessage operators typically gain initial access through compromised credentials, phishing emails containing malicious attachments, or exploitation of vulnerabilities in internet-facing systems. Once access is achieved, attackers move to identify critical systems, sensitive data, and network segments.

Data exfiltration is carried out prior to encryption, increasing leverage even where backups exist. Ransomware is then deployed across the network, targeting Windows systems and, in some cases, Linux operating systems.

The MoneyMessage encryptor uses a defined encryption process that may include an embedded JSON configuration file, configurable file extensions, and attempts to terminate processes and delete volume shadow copies to hinder recovery. Victims are instructed to access payment instructions via the Tor browser, with deadlines imposed to encourage rapid engagement.

We are equipped to deal with an attack from any ransomware group.

Don’t hesitate to contact us if you are under attack from a ransomware group not listed above. 

Recognising a MoneyMessage attack

A MoneyMessage ransomware attack is typically identified by encrypted files, new file extensions, and the appearance of a ransom note demanding cryptocurrency payment. Organisations may also observe evidence of stolen data, unusual log activity, or system outages affecting critical services.

In some incidents, shadow copies may be deleted and security controls disabled, increasing the difficulty of system recovery and prolonging operational disruption.

Why you must not interfere with your ransomware environment

If you discover a physical break-in at your offices, your first instinct would be to call the police; touch nothing and let them search for clues. Then, your focus would shift to restoring business operations.

A cyber-attack requires the same approach. Your digital environment is a CRIME SCENE. It is crucial to leave the environment untouched to allow for a forensic investigation.

This is not a task for your IT team or MSP. Digital Forensic specialists are available 24/7 to assist you, just like in a physical crime.

Post breach actions

  • Call a NCSC Cyber Incident Response approved supplier Some NCSC providers will fund up to 48 hours of investigation into your incident.
  • Report the incident to Report Fraud
  • Locate your business continuity plan Work out what you can do without access to your systems and data.
  • Identify your business insurance contact details

  6. Rebuild your systems, restore your data and get you back to full operation. Note: This process can take between 2 weeks – 2 months.

 

Working with us

Our response process

Our team are ransomware recovery specialists with a proven, streamlined approach to resolving incidents quickly and effectively.

Step 1: Triage

We deploy our incident response team the same day. From the first call, we begin onboarding, introduce key stakeholders, set communication schedules, and start gathering critical information to guide the response.

Step 2: Investigation

DFIR (Digital Forensic Incident Response) teams investigate breaches to identify vulnerabilities, attack vectors, and system impacts from ransomware such as Data Loss (PII). We deliver clear forensic insights to guide mitigation.

Step 3: Contain

Our onsite and remote teams act fast to stop the attack in its tracks. That includes isolating affected systems, removing malicious code, and putting protections in place to prevent further spread or damage.

Step 4: Remediate & Eradicate

Once contained, we work to fully eliminate the threat. This includes fixing exploited vulnerabilities, restoring systems to a secure state, and ensuring no traces of the attack remain.

Step 5: Recover

Our incident response teams help get your business back to normal. We restore access to systems, recover data, and ensure services are safe, stable, and functioning, with minimal downtime.

Step 6: Post Incident

We conduct a full review of the incident response and recovery efforts. Together we assess what happened, what worked, and what can be improved, helping you build stronger defences for the future.

Forensic analysis to drive recovery

Our process includes a thorough digital forensic analysis from step two where the output becomes a central component of business recovery. This is because understanding the attack is of critical importance:

  • Informing an initial infection date

  • The extent and spread of infection

  • Data exfiltration having an impact on regulatory positions

  • Ensuring that the attacker and any tooling or artefacts they leave behind are eradicated

It is critical that the analysis of digital evidence is carried out to an agreed plan.

Maximising early root cause discovery and legal leverage

The process is purpose-built to uncover the root cause as early as possible, 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.

Our Digital Forensic and Incident Response (DFIR) 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.

Key take aways

  • You will not be able to access your systems or data.
  • It is advised to disconnect from the internet and shut down your systems, including PCs, to prevent further infections.
  • Your Office 365 system might also be compromised, allowing the attackers to monitor your responses. Avoid communicating with individuals through your primary email or team systems.
  • Threat actors typically infiltrate your system at least 2-4 weeks before you become aware of the attack. Your data will have already been exfiltrated. If your system is encrypted, this was not an overnight event.
  • Ransom demands in the UK typically range from £500,000 to £3 million, with some sectors, like education, facing demands that exceed £5 million
  • Paying the ransom may violate financial sanctions, which is a criminal offence and could result in a custodial sentence or further financial penalties.
  • If your data is sold or published online, it puts your customers and staff at risk, potentially implicating you in a Data Protection breach.
  • You will need to submit a data takedown request to the initial location where the data was transferred.
  • Do not overwrite the encrypted data. It is crucial to determine when the infection began and where the data was sent.
  • Avoid rebuilding from the latest backup, as it is likely to be infected.

Why should I trust Zensec to do this work rather than my IT team?

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:

Internal IT teams don’t have the necessary skill set to resolve security encryption issues themselves. 

IT teams may recover to the same position with indicators of compromise ready to do it again… which can lead to another breach.

Internal teams are pressured to restore business operations and may recover before forensic analysis even begins, potentially destroying the crime scene before completion.
