1.Weekly Update                           

Statistical period: October 31, 2026 ~ November 6, 2026

Antiy AVL SDK anti-virus engine released a total of 84 virus database updates this week, with an average of 12 updates per day, adding 37 new detectable malicious code families, 8,860 new detectable malicious code variants, and 17,750 new detection rules.

The following table shows the TOP5 newly detectable malicious code families:

NumberVirus NameVirus Description
1Trojan/Win32.SapphireMinerThis family is a type of Trojan virus, usually spreading through software bundling, spam email attachments or malicious websites. It is mainly used for cryptocurrency mining on infected computers.
2Trojan/Win64.CapDoor[Backdoor]This family is a type of Trojan virus that gains access to the victim’s computer system by deceiving the user or by carrying other malicious software. Once infected, it runs in the background and stealthily steals sensitive information, monitors the user’s activities, and sends data to a remote server.
3Trojan/Win64.VexLoggerThis family is a type of Trojan virus. It mainly lurks in computer systems through Trojan programs, monitoring users’ keyboard inputs and screen operations, and recording sensitive information such as account numbers and passwords.
4Trojan/Win64.GolstaStealerThis family is a type of Trojan virus, mainly spreading through phishing emails, malicious download links or software attachments. Once it infects a user’s computer, it will hide itself and steal sensitive information such as account passwords and bank card details, thereby endangering the user’s privacy and security.
5Trojan/Linux.Cerber[Ransom]This family is a type of Trojan virus. Initially, it was known for its ransomware payload on the Windows platform. Later, it emerged as a variant on the Linux platform, belonging to the RaaS ransomware-as-a-service type of malicious code. The sample is an ELF executable file, mainly targeting storage devices exposed on the public network. The attackers usually obtain the device administrator privileges by bypassing authorization and exploiting remote code execution vulnerabilities and then deliver this payload. After the malicious code runs, it traverses the target directory, encrypts the user’s business data, modifies the file extensions, and releases the ransom note in the directory, demanding that the victim pay a ransom to a designated dark web address in exchange for the decryption key, resulting in the unavailability of the business data.

3. Be on Guard Against These Virus Families This Week

Be vigilant against the Cerber ransomware variant C3RB3R Linux variant attack activities this week. Recently, Antiy CERT monitoring has discovered that since October 28, 2026, there has been a concentrated ransom attack activity on exposed public storage devices on the internet. The attack payload is the Linux platform variant of the Cerber ransomware targeting Synology NAS devices. The security community, based on the ransom letter identification and dark web contact information, has temporarily named this variant as “C3RB3R”. This family was initially known for spreading on the Windows platform. This variant mainly targets exposed public storage devices and the attackers mainly use authorization bypass and remote code execution vulnerabilities to obtain administrator privileges to carry out the intrusion.

Appendix: Introduction to Antiy AVL SDK Anti-Virus Engine

Antiy AVL SDK anti-virus engine is a threat detection capability middleware developed by Antiy for all architectures and system platforms. By embedding the AVL SDK, Antiy products and ecosystem partners’ products can acquire virus and malicious code detection capabilities, and receive continuous updates through the virus database.

For eight malicious code categories including infectious viruses, worms, Trojans, hacking tools, gray software, risky software, junk files, and test files, it accurately identifies and detects over 50,000 families and 18 million malicious code variants. The detection capability fully covers all known malicious codes and strictly adheres to the CARO convention. The output is structured and named in sections by classification, environment, and family, and based on the behavioral capabilities of malicious samples, it outputs nearly a hundred types of malicious behavior tags for typical malicious behaviors such as encryption ransomware, data theft, remote control, botnet programs, and mining. Antiy Engine can recognize over 300 file formats and conduct in-depth preprocessing on compilable executable formats such as PE and ELF. It also performs recursive unpacking of various packages (including self-extracting archives), and conduct structural analysis of compound documents such as OFFICE and ACAD files that may contain embedded scripts or vulnerability-prone formats. This ensures high robustness against malicious code. Antiy Engine also comes with a trusted file signature library, supporting the product to implement security policies based on blacklist and whitelist controls, significantly enhancing the difficulty for attackers.

Antiy’s detection capabilities can be fully deployed locally. Antiy automatically analyzes and processes over 2 million new file objects on average every day and releases a virus database update every two hours. It also provides support services such as cloud detection, cloud analysis, and computer virus encyclopedia.
