AllCiphered Ransomware Decryptor

Comprehensive Analysis and Decryption Guide using Medusa Decryptor

First identified in December 2024, AllCiphered Ransomware has quickly risen to prominence as one of the most dangerous cyber threats of recent times. This highly sophisticated ransomware strain encrypts files on compromised systems, rendering critical data inaccessible until a ransom is paid. Operating under a Ransomware-as-a-Service (RaaS) model, AllCiphered is an offshoot of the notorious MedusaLocker ransomware family. Its business model enables widespread distribution by leveraging affiliates, who retain a significant share of the ransom proceeds. This has led to widespread infections, with healthcare organizations and other vulnerable sectors often bearing the brunt of these attacks.

Propagation Methods

AllCiphered utilizes multiple sophisticated methods to infiltrate systems and propagate across networks, exploiting both human error and technical vulnerabilities. Below are the most common techniques:

1. Phishing Emails

Phishing emails remain a primary avenue for distributing AllCiphered. These emails are cleverly disguised as legitimate messages from trusted sources, containing either malicious attachments or links that initiate the ransomware infection upon interaction.

Key Indicators of Phishing Emails:

• Suspicious attachments (e.g., .exe, .zip, or .pdf files).
• Hyperlinks redirecting to malicious or unknown websites.
• Urgent language prompting immediate action.
• Poor grammar or unusual sender addresses.

2. Exploitation of Software Vulnerabilities

Unpatched systems and outdated software are frequent targets for AllCiphered. Attackers actively scan for such vulnerabilities to gain unauthorized access.

Commonly Exploited Weaknesses:

• Outdated operating systems and web applications.
• Remote Desktop Protocol (RDP) vulnerabilities.
• Default or weak administrative credentials.

3. Network Propagation

Once inside a network, AllCiphered spreads laterally, compromising multiple systems. It employs stolen credentials or exploits poorly configured network permissions to propagate.

Tactics for Network Spread:

• Use of stolen admin credentials.
• Exploiting open network shares.
• Deployment of remote access tools for lateral movement.

4. Drive-by Downloads

In this method, unsuspecting users download ransomware through compromised websites or malicious advertisements.

Signs of Drive-by Downloads:

• Pop-ups urging fake software updates.
• Unexpected software installations.
• Redirects to suspicious or unknown sites.

5. Remote Desktop Protocol (RDP) Exploits

Exposed RDP ports are a frequent target for AllCiphered operators. Attackers employ brute force techniques to gain access and install the ransomware.

RDP Attack Techniques:

• Exploitation of weak passwords.
• Credential stuffing attacks using previously stolen credentials.
• Scanning for exposed RDP ports accessible online.

6. Ransomware-as-a-Service (RaaS)

Operating under an affiliate model, AllCiphered is distributed through underground forums. Affiliates use phishing kits, stolen credentials, and other tools to spread the ransomware, splitting profits with its developers.

The Encryption Process

AllCiphered employs robust encryption techniques to lock victims’ data effectively.

1. Encryption Key Generation

• AES-256 Encryption: A unique key is generated for every victim to secure files.
• RSA-2048 Public Key: The AES key is encrypted and sent to the attacker’s command-and-control (C&C) server, ensuring no local key recovery.

2. Selective File Targeting

• Efficiency: Specific file types (e.g., documents, images, and databases) are targeted to maximize impact.
• Renaming: A unique extension like .AllCiphered70 is appended to encrypted files to signify compromise.

3. Volume Shadow Copy Deletion

AllCiphered deletes Windows Volume Shadow Copies to prevent recovery through traditional means like System Restore or file backups.

Ransom Note and Payment Instructions

Once encryption is complete, AllCiphered leaves a ransom note in every directory with encrypted files.

Context of the Ransom note:

“
YOUR PERSONAL ID:
–

/!\ YOUR COMPANY NETWORK HAS BEEN PENETRATED /!\
All your important files have been encrypted!

Your files are safe! Only modified. (RSA+AES)

ANY ATTEMPT TO RESTORE YOUR FILES WITH THIRD-PARTY SOFTWARE
WILL PERMANENTLY CORRUPT IT.
DO NOT MODIFY ENCRYPTED FILES.
DO NOT RENAME ENCRYPTED FILES.

No software available on internet can help you. We are the only ones able to
solve your problem.

We gathered highly confidential/personal data. These data are currently stored on
a private server. This server will be immediately destroyed after your payment.
If you decide to not pay, we will release your data to public or re-seller.
So you can expect your data to be publicly available in the near future..

We only seek money and our goal is not to damage your reputation or prevent
your business from running.

You will can send us 2-3 non-important files and we will decrypt it for free
to prove we are able to give your files back.

“

Key Elements of the Ransom Note:

1. Payment Instructions: Detailed steps for paying the ransom, typically in Bitcoin.
2. Contact Channels: Email addresses or links to communication portals on the Tor network.
3. Deadlines and Threats: A time limit for payment, with threats of data deletion or public exposure for non-compliance.

---

In addition to encrypting data, attackers often exfiltrate sensitive information, threatening to leak it if the ransom isn’t paid. This double extortion tactic increases pressure on victims, particularly organizations with sensitive data.

---

Persistence Mechanisms

AllCiphered is designed to maintain its presence even after initial detection.

1. Strategic System Installation

• File Placement: Stores executables in obscure directories like %AppData%\Roaming.
• Mimicry: Uses file names that resemble legitimate processes, such as svhost.exe.

2. Scheduled Tasks

• Creates recurring tasks in Windows Task Scheduler to ensure persistence after system reboots.

3. Network Propagation

• Targets shared network drives and uses services like LanmanWorkstation to infect additional machines.

4. Defense Evasion

• Process Termination: Disables antivirus software and essential services.
• Obfuscation: Masks itself as legitimate processes to bypass detection.

---

Prevention Strategies

Preventing AllCiphered attacks requires layered cybersecurity measures:

1. Strong Authentication

• Use complex passwords and enable Multi-Factor Authentication (MFA) to secure remote access points.

2. Employee Training

• Conduct phishing awareness campaigns and teach safe browsing practices.

3. Regular Updates

• Patch all software and systems to close known vulnerabilities.

4. Network Segmentation

• Isolate critical systems from the broader network to limit ransomware spread.

5. Air-Gapped Backups

• Store backups offline to prevent them from being encrypted during an attack.
