Spectra ransomware is a malicious file-encrypting threat discovered through samples uploaded to the VirusTotal platform. It is based on the Chaos ransomware family and is designed to lock victims’ files and demand payment in exchange for a decryption key. Once executed on a victim’s system, Spectra encrypts files and appends four random characters to the filenames as extensions (e.g., 1.jpg
becomes 1.jpg.hecm
). Victims also find a ransom note titled “SPECTRARANSOMWARE.txt”, detailing the ransom demands and threats.

Behavior of Spectra Ransomware
Spectra spreads using typical ransomware distribution vectors, including infected email attachments, torrent websites, and malicious ads. Upon successful infiltration, it encrypts vital documents, databases, executables, and other essential data, rendering them unusable without the attacker’s decryption key.
The ransom note claims that the attackers have compromised not only the primary data but also backup systems, making recovery nearly impossible without paying the ransom. Victims are demanded to pay $5000 in Bitcoin to a provided wallet address within 72 hours, or risk permanent data loss, public data exposure, network-wide attacks, and disclosure of security vulnerabilities.
Text from “SPECTRARANSOMWARE.txt” Ransom Note:
CONFIDENTIAL AND URGENT
To the Management and IT Department of your company,
You are now faced with a critical situation. Your company's digital assets, including sensitive data, financial records, and intellectual property, have been compromised. Our group has successfully infiltrated your network, exploiting vulnerabilities that your security measures failed to address.
As a result, we have encrypted all accessible data, rendering it inaccessible to your organization. The encryption method used is highly sophisticated, and decryption without our provided key is virtually impossible. Your attempts to restore from backups will be futile, as we have also compromised your backup systems.
The following data has been encrypted and is currently being held for ransom:
Financial records, including invoices, payments, and accounting data
Sensitive customer information, including personal identifiable data
Proprietary software and intellectual property
Email communications and internal memos
Database files, including SQL and NoSQL data
We are willing to provide the decryption key in exchange for a payment of $5000 in Bitcoin. This amount is non-negotiable, and any attempts to bargain or delay payment will result in the permanent deletion of your data.
You have 72 hours to comply with our demands. Failure to pay the ransom within the specified timeframe will result in:
1. Permanent deletion of your encrypted data
2. Public release of sensitive customer information
3. Disclosure of your company's security vulnerabilities to the public and competitors
4. Initiation of a targeted attack on your remaining infrastructure
To facilitate the payment process, we have provided a Bitcoin wallet address below:
19DpJAWr6NCVT2oAnWieozQPsRK7Bj83r4
Once the payment is confirmed, we will provide the decryption key and instructions on how to restore your data. Please note that any attempts to involve law enforcement or cybersecurity firms will be detected, and we will take immediate action to destroy your data.
You are advised to take this situation seriously and act promptly to avoid any further consequences. We are monitoring your company's activities closely and will respond accordingly.
DO NOT IGNORE THIS MESSAGE
Your company's future depends on your prompt response to this situation. We expect your cooperation and payment within the specified timeframe.
Sincerely,
Spectra Ransomware
