An infection with Flocker, 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 published online.
A break-in at your offices would compel you to call the police immediately and touch nothing until they arrive, understanding the need for forensic work to take place.
A cyber-attack requires the same action. Your first responsibility would be to call in the forensic experts and ensure the environment remains untouched.
This is not a job for your IT team or MSP. There are digital forensic specialists available 24/7 who can assist you.
First identified in late 2023, Flocker is a relatively new ransomware group known for its aggressive attack methods and swift expansion across multiple sectors. While its exact origins remain unclear, security researchers have linked its tactics and tools to other prominent ransomware families, suggesting that Flocker could be an evolution of a previously known group.
Flocker primarily targets Windows and Linux systems, distributing its malware through phishing emails, compromised remote desktop protocol (RDP) credentials, and exploit kits. Once inside a network, Flocker rapidly encrypts files and exfiltrates sensitive data, leveraging a double extortion model. Victims are not only locked out of their systems but also threatened with the public release of stolen information if they fail to pay the ransom.
Due to its aggressive tactics and growing number of successful attacks, Flocker is expected to become an increasingly dangerous threat to businesses worldwide. Security researchers continue to monitor its activities, warning organisations to bolster their cybersecurity measures against this evolving ransomware threat.
Flocker follows the increasingly common double extortion method, combining file encryption with data theft. This approach forces victims into paying, even if they have backups, as the threat of exposing confidential business information can lead to severe financial and reputational damage.
Once deployed, the ransomware encrypts crucial files, displaying a ransom note demanding payment in cryptocurrency. In many cases, Flocker also disables security tools and attempts to delete backups to make recovery more difficult. If the ransom is not paid, stolen data is often leaked on dark web forums or sold to other cybercriminals.
Emerging in late 2023, Flocker is a relatively new player in the ransomware landscape, but its rapid growth suggests a well-organised operation. Reports indicate that within its first few months, Flocker has claimed dozens of victims across various industries, including healthcare, finance, and manufacturing.
To date Flocker has claimed responsibility for 40 successful attacks.

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 Flocker, 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.
A Flocker ransomware attack generally enters a system in one of the following ways:
We recommend you adopt policies to:
After recovering from Flocker Solace Cyber recommends that you update your business continuity plan to account for lessons learnt during this attack & recovery.
The average cost of ransomware breaches hover around £500K, while smaller email data breaches typically incur expenses of around £50K. A critical decision emerges between preserving the environment for forensic analysis or opting for swift recovery to minimise business disruption. Delays in identifying and resolving breaches only exacerbate costs.
Cybersecurity insurance claims entail a multifaceted process, encompassing reasonable expenditures for investigation and remediation, alongside coverage for legal, business interruption, criminal liability, employment liability, and ransom policies. While the insurance industry plays a pivotal role in facilitating business recovery, cyber insurance is perceived as volatile within the sector, and many policies require meticulous validation.
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.
