Understanding Spider Ransomware

Origin and Classification

Spider ransomware first caught the attention of cybersecurity researchers during routine analyses of new malware submissions on platforms like VirusTotal. Initial investigations quickly revealed its connection to the well-established MedusaLocker ransomware family, known for its sophisticated encryption techniques and aggressive extortion tactics.

As a variant of MedusaLocker, Spider inherits many of its predecessor’s characteristics while introducing unique elements that set it apart. This lineage provides valuable insights into its potential behavior and impact, allowing researchers and security professionals to draw upon existing knowledge of the MedusaLocker family in their efforts to combat this new threat.

Encryption Process and File Identification

To gain a comprehensive understanding of Spider’s modus operandi, cybersecurity experts executed samples of the ransomware in controlled environments. The results were alarming, showcasing the malware’s efficiency and destructive potential:

1. Rapid Encryption: Upon infection, Spider swiftly begins encrypting files across the system, targeting a wide range of file types including documents, images, databases, and other potentially valuable data.
2. Distinctive File Extension: The ransomware appends a unique extension to each encrypted file: “.spider2” or “.spider1”. For example, a file originally named “important_document.docx” would be transformed into “important_document.docx.spider2” post-encryption.
3. System-Wide Impact: The encryption process is thorough, affecting files on local drives, connected network shares, and even removable storage devices, maximizing the impact on the victim’s data.

Ransom Note and Extortion Tactics

Upon completing its encryption routine, Spider ransomware leaves behind a ransom note titled “How_to_back_files.html” on the victim’s system. This HTML file serves as the primary means of communication between the attackers and their victims, outlining the dire situation and presenting their demands.

The ransom note is crafted to exploit the psychological vulnerabilities of victims, employing fear, urgency, and pressure to coerce compliance. Key elements of the ransom note include:

1. Claim of Network Compromise: The attackers assert that they have gained complete access to the victim’s network, implying a deep-seated and widespread infection.
2. Data Exfiltration Threat: In addition to encrypting files, the ransomware operators claim to have extracted sensitive data, threatening to release or sell this information if their demands are not met. This double-extortion tactic has become increasingly common among ransomware groups, significantly raising the stakes for victims.
3. Encryption Details: The note explains that files have been encrypted using a combination of RSA and AES algorithms, emphasizing the futility of attempting decryption without the attackers’ assistance.
4. Warnings Against Recovery Attempts: Victims are strongly cautioned against modifying encrypted files or using third-party recovery tools, with claims that such actions will result in permanent data loss.
5. Proof of Decryption Capability: To demonstrate their ability to restore the encrypted data, the attackers offer to decrypt up to three non-critical files for free. This tactic is designed to build credibility and increase the likelihood of ransom payment.
6. Time Pressure: A 72-hour deadline is imposed for establishing contact with the attackers. After this period, the ransom amount is set to increase, creating a sense of urgency.
7. Payment Instructions: Detailed instructions for making the ransom payment, typically in cryptocurrency, are provided along with contact information for the attackers.

The psychological manipulation employed in the ransom note underscores the sophistication of Spider’s operators and the broader ransomware ecosystem. By leveraging fear, urgency, and the threat of data exposure, these cybercriminals aim to maximize their chances of receiving payment.

Technical Analysis

Encryption Algorithms

Spider ransomware employs a powerful combination of encryption algorithms to secure its victims’ files, making unauthorized decryption virtually impossible. The two primary algorithms used are:

1. RSA (Rivest-Shamir-Adleman): This asymmetric encryption algorithm is used to encrypt the AES key. RSA’s strength lies in its use of a public key for encryption and a private key for decryption, making it ideal for secure key exchange.
2. AES (Advanced Encryption Standard): A symmetric encryption algorithm, AES is employed for the bulk encryption of files due to its speed and efficiency in processing large amounts of data.

The encryption process typically follows these steps:

1. The ransomware generates a unique AES key for the current infection.
2. Files are encrypted using this AES key.
3. The AES key is then encrypted using the attacker’s public RSA key.
4. The encrypted AES key is stored, typically within the encrypted files or in a separate file.

This dual-layer encryption strategy ensures that even if a victim were to somehow obtain the encrypted AES key, they would still need the attacker’s private RSA key to decrypt it and subsequently decrypt their files.

File Targeting and Enumeration

Spider ransomware is designed to target a wide range of file types, focusing on documents, images, databases, and other potentially valuable data. The malware maintains an internal list of file extensions to encrypt, ensuring that system files crucial for the computer’s operation remain untouched.

The file targeting process typically involves:

1. File System Traversal: The ransomware recursively scans all accessible drives, including local disks, network shares, and removable storage devices.
2. Extension Checking: Each file encountered is checked against the internal list of target extensions.
3. Size Limitation: Some variants may impose a maximum file size for encryption to ensure rapid completion of the process.
4. Whitelisting: Certain system directories and file types may be whitelisted to prevent rendering the system inoperable.

This comprehensive approach maximizes the impact on the victim and increases the likelihood of encrypting critical data, thus enhancing the ransomware’s leverage for extortion.

Persistence Mechanisms

To ensure its continued presence on the infected system, Spider ransomware employs various persistence techniques, such as:

1. Registry Modifications: The malware may create or modify registry keys to enable automatic execution upon system startup.
2. Scheduled Tasks: Creation of scheduled tasks to periodically run the malware, ensuring it remains active even if temporarily removed.
3. Process Disguise: The ransomware may disguise itself as a legitimate system process to evade detection by users and some security software.
4. Service Creation: In some cases, the malware might create a Windows service that appears legitimate but serves to maintain its presence on the system.
5. File Attribute Manipulation: Changing file attributes to hidden or system files can help the malware avoid casual detection.

These persistence mechanisms make it challenging to completely eradicate the ransomware without a thorough system cleanup, often necessitating professional intervention or complete system restoration.
