Technical Characteristics
File Encryption Process
Upon infection, Numec initiates an encryption routine targeting a wide array of file types. Utilizing robust cryptographic algorithms, it ensures that the affected files are rendered inaccessible without the corresponding decryption key.

File Extension Changes
A hallmark of Numec’s operation is the alteration of file extensions. Encrypted files are appended with the “.numec” extension, transforming, for example, “document.docx” into “document.docx.numec”. This change serves both as an indicator of infection and a method to prevent standard access to the files.
Creation of EncryptedFiles Folder
Numec consolidates the encrypted files into a newly created folder named “EncryptedFiles” located on the victim’s desktop. This centralized location simplifies the attacker’s process of managing the encrypted data and issuing ransom demands.
Ransom Note Details
Numec delivers a ransom note titled “GetFilesBack.txt” within the “EncryptedFiles” folder. The note outlines the steps victims must follow to potentially recover their data.

Distribution Methods
Numec employs various vectors to infiltrate systems:
- Email Attachments: Malicious emails with infected attachments or links are a common delivery method.
- Malicious Downloads: Downloading software or files from unverified sources can lead to infection.
- Exploitation of Vulnerabilities: Attackers may exploit security flaws in software or operating systems to deploy Numec.
Detection and Identification
Security solutions have identified Numec under various detection names:
- Avast: Script:SNH-gen [Trj]
- ESET-NOD32: PowerShell/Filecoder.CU
- GData: Script.Trojan.Agent.776P2A
- Microsoft: Trojan:PowerShell/Conti.MZZ!MTB
- Symantec: Ransom.Gen
Behavioral indicators include:
- Sudden changes in file extensions.
- Appearance of the “EncryptedFiles” folder on the desktop.
- Presence of the “GetFilesBack.txt” ransom note.
Impact on Victims
The consequences of a Numec infection are severe:
- Data Loss: Encrypted files become inaccessible, leading to potential loss of critical data.
- Operational Disruptions: Businesses may experience downtime, affecting productivity and revenue.
- Financial Implications: Costs associated with recovery efforts, potential ransom payments, and reputational damage can be substantial.
Recommended Response Actions
Immediate Steps Post-Infection
- Isolate the Infected System: Disconnect from networks to prevent further spread.
- Do Not Pay the Ransom: Paying does not guarantee data recovery and may encourage further criminal activity.
- Consult Cybersecurity Professionals: Engage experts to assess the situation and explore recovery options.
Communication with Attackers
While direct communication is discouraged, if pursued, it should be conducted cautiously, preferably under the guidance of law enforcement or cybersecurity professionals.
Data Recovery Options
- Backups: Restore data from clean backups if available.
- Decryption Tools: Check resources like the No More Ransom Project for potential decryption solutions.
Prevention Strategies
Implementing robust cybersecurity measures can mitigate the risk of ransomware infections:
- Regular Backups: Maintain up-to-date backups stored offline.
- Security Software: Use reputable antivirus and anti-malware programs.
- User Education: Train users to recognize phishing attempts and avoid suspicious downloads.
- System Updates: Keep operating systems and applications updated to patch vulnerabilities.
Legal and Ethical Considerations
- Reporting Incidents: Notify appropriate authorities and comply with legal obligations.
- Law Enforcement Involvement: Engage with law enforcement agencies for guidance and support.
- Ethical Implications of Paying Ransoms: Consider the broader impact of ransom payments on cybercrime proliferation.
