Embargo Ransomware

Experiencing Ransomware or Cyber Breach?

Response time is everything when you're under attack. If you've been breached or have an urgent matter, contact us immediately.

Embargo is a geopolitically motivated ransomware group that began operating in late 2023, believed to be linked to state-sponsored cyber campaigns.

Victims find their systems locked with a politically charged ransom note demanding payment and sometimes referencing international sanctions or government activity.

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 attention would turn towards getting your business operations back up and running.

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 available 24/7 to assist you, just like in a physical crime.

Who is Embargo? What does it do?

Unlike traditional ransomware groups, Embargo mixes financial gain with political messaging. It often targets public sector organisations, NGOs, and critical infrastructure.

Embargo’s encryption technique includes appending a .embg extension and leaving highly customised ransom notes.

How Does Embargo Attack?

  • Spear-phishing emails and waterhole attacks
  • Exploits zero-days for initial access
  • Encrypts data while exfiltrating high-value files
  • Includes geopolitical messages in ransom notes

Embargo has been observed creating fake data leaks to amplify pressure on victims.

How old is Embargo and how many attacks have there been?

Embargo was first seen in Q4 2023. Fewer than 20 confirmed attacks have been reported, but the high-value nature of its targets has earned it strong attention from threat analysts.

Experiencing Ransomware or Cyber Breach?

Response time is everything when you're under attack. If you've been breached or have an urgent matter, contact us immediately.

Why should I trust Solace Cyber 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.
  • Internal teams are pressured to restore business operations and may recover before forensic analysis even begins, potentially destroying the crime scene before completion.
  • IT teams may recover to the same position with indicators of compromise ready to do it again…. which can lead to another breach.
  • In 2022, there were not enough adequately qualified people in the job market to meet the CSIRT* resource requirements.
  • Cybercrime has stepped up again in 2024.

Solace Cyber was established precisely for this scenario. We have a well-defined process for handling cyber-attacks like Embargo, which involves a 6-step approach:

  1. Triage
  2. Analysis
  3. Contain and Mitigate
  4. Remediate and Eradicate
  5. Recover
  6. Post-Incident Examination

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:

  • 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. 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.

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 can range from £0.5 million to £3 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.
How do I maintain security in future to prevent a further ransomware attack?

Solace Cyber's assistance extends beyond the recovery phase. Following the restoration of your business operations, we collaborate with you to enhance your cyber security posture using a threat-informed methodology. This involves leveraging our Cyber 9 Step Process, designed to comprehensively address cyber threats and vulnerabilities.

Frequently asked questions

Yes, Embargo is ransomware with political motives, encrypting data and demanding ransom under the guise of activism or retaliation.

The Embargo ransomware entered your system by one of several ways:

  • Spear-phishing
  • Visiting Compromised Websites

We recommend you adopt policies to:

  1. Educate your staff on the importance of cyber security
  2. Use strong passwords
  3. Multi-factor authentication
  4. Remove old users
  5. Perform regular backups
  6. Deploy timely updates to software and systems

After recovering from a Embargo ransom attack, Solace Cyber recommends that you update your business continuity plan to account for lessons learnt during this attack & recovery.

Most ransomware breaches cost approximately £500K, while smaller email data breaches typically cost around £50K. There is a critical balance between preserving the environment for forensic analysis and quickly recovering it to minimise business interruption. The costs increase the longer it takes to identify and resolve the breach.

A cyber security insurance claim is complex, covering reasonable expenses for investigating and remediating an incident, along with legal fees, business interruption, criminal liability, employment liability, and ransom payments. Although the insurance industry is responsible for facilitating business recovery, cyber insurance is viewed as volatile, and many policies are not being validated correctly.

Finding your way through demands expertise, and that's where Solace Cyber can offer assistance.

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.

The NCSC have documented the deliberations for paying ransomware: https://www.ncsc.gov.uk/ransomware/home

Important Reminder: It is a criminal offense to pay money to people who are subject to financial sanctions. The list of who is subject to financial sanctions is constantly changing.

The latest iteration can be found here: https://www.gov.uk/government/publications/financial-sanctions-consolidated-list-of-targets

Yes. There's a possibility that some of the lost data falls under the category of "Personal Data" belonging to your customers. It's your legal responsibility to safeguard this data, even if it has been lost. Additionally, you may need to notify the Information Commissioner's Office at https://ico.org.uk/.

Your insurer or legal counsel will provide guidance on the necessary steps and how to move forward in this situation.

Solace has experience collaborating with insurers and legal professionals and can offer support in managing this relationship during this challenging period.

A ransomware attack presents the most significant threat to your business by:

  • Disabling your access to systems, which could hinder machinery operation or impede progress through your business processes.
  • Blocking access to critical data concerning suppliers, shipments, customers, orders, or steps in your business workflow.

In the event of a business interruption, determining your position in the supply chain for any item and sustaining operations become challenges. If the disruption persists, maintaining business continuity becomes paramount. Moreover, upon restoration of systems and data, addressing any backlog of work and establishing operational protocols for the future becomes essential.

Ransomware ranks only behind receivership in terms of its capacity to incapacitate a business.
