Madliberator Ransomware

Under attack by ransomware or suffering a cyber breach?

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

About Madilberator ransomware group

Madliberator ransomware is a chaotic ransomware group that emerged in early 2024. Madliberator attackers are known for erratic behaviour, randomised ransom demands, and unpredictable data encryption. Some systems may be wiped, others have only partial encryption, while a ransom note demands wildly different sums from one victim to the next.

Madliberator attackers often use meme-style or surrealist ransom notes as part of their social engineering tactics. Victims may see bizarre pop-up messages on affected systems or even have files deleted with little logic. Many organisations have reported sensitive data being stolen, corrupted or published on a data leak site.

How Madilberator operators work

The Madliberator ransomware group appears to focus on disruption more than financial gain. Victims include schools, local councils, charities, and small businesses. Madliberator attackers use a mix of phishing emails, unsolicited AnyDesk connection requests, and brute force attacks to gain initial access. Sometimes, users clicked accept on an incoming connection request believing it was their IT department performing maintenance, only to allow attackers access to the system.

After gaining access, the threat actors may use advanced IP scanner tools and disable user input, making it difficult for end users to stop the attack. They steal sensitive data from victim devices, including the victim’s OneDrive account and other files stored locally or in the cloud. The .madlib extension is often used to mark encrypted files, and lateral movement is common as the ransomware group spreads through the network.

Ransom notes and ransom demands may refer to “just a usual instance” or “usual instance,” sometimes suggesting prior interaction or referencing other devices or business operations.

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

Recognising a Madilberator attack

Madliberator ransomware gains initial access using brute force, exploit kits, and phishing emails. The group is known for deploying odd, “madlib-style” ransom notes and using the .madlib extension. Attacks may involve inconsistent or partial encryption, with some incidents featuring data corruption or outright deletion. Victims often encounter bizarre pop-up messages and ransom notes, adding to the disruption and confusion.

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.

We are accredited to ISO 27001 and recognised by the UK’s National Cyber Security Centre (NCSC).

We provide comprehensive cyber risk management services, with a core focus on Digital Forensics and Incident Response (DFIR). Our capabilities are driven by a 24/7 Security Operations Centre and a dedicated in-house intelligence team that delivers timely, actionable threat reporting.

With decades of collective cyber security experience, we have the expertise to assume operational ownership of your entire IT security architecture – simplifying and strengthening cyber security across your business.

As an Assured Service Provider for Cyber Incident Response (CIR) at the Standard Level. This accreditation demonstrates our ability to deliver high-assurance, effective support in response to a wide range of cyber threats.

Your NCSC-approved supplier is a specialist crime scene investigator who will:

  1. Isolate and preserve your environment for forensic investigation.
  2.  Identify where the data has been duplicated and issue a legal takedown order.
  3. Identify your data, application and systems restore points. These might be at different points in time and will need to be carefully restored and reconstructed in a pristine environment.
  4.  Liaise with your business insurance company and if needed, with the Police.
  5. Advise you on notifying your customers of your situation.
  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.

Frequently asked questions

Key information when you’re under pressure.

Recovering from a Madliberator ransomware attack can be expensive, especially when threat actors have exfiltrated or leaked sensitive data. Costs often exceed £50,000, even for smaller data breaches. While many cyber insurance policies do include incident response, forensic investigation, and legal advice, insurers may require evidence that you engaged an NCSC-approved supplier for your response. Always check your policy and notify your insurer as soon as possible.

Paying a ransom to Madliberator or any similar group is extremely risky. These threat actors have been known to continue their extortion attempts, even after a payment is made. There is no assurance that files will be restored, or that stolen data will not be published or sold. It is strongly recommended to involve a professional incident response team who are experienced with Madliberator tactics and can help you manage the situation effectively.

See official advice here: NCSC ransomware guidance
Note: It is a criminal offence in the UK to pay those on the financial sanctions list.

Madliberator’s ransomware operations often result in severe disruption to business critical systems, halting essential operations and damaging trust. The aftermath may require weeks or even months to fully restore data and rebuild customer confidence. If social engineering tactics were used to steal sensitive data, regulatory penalties and legal challenges may follow, particularly if information is exposed online.
