1.Weekly Update                           

Statistical period: August 22, 2026 ~ August 28, 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 42 new detectable malicious code families, 14,720 new detectable malicious code variants, and 38,672 new detection rules.

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

Number	Virus Name	Virus Description
1	Trojan/Win32.Roclis[Ransom]	This family of malware is a type of Trojan virus that typically spreads through phishing emails, malicious downloads, or exploit attacks. Once a system is infected, the malware encrypts the user’s files and demands a ransom in exchange for the decryption key, posing a serious threat to computer systems.
2	Trojan/MSIL.HyperScrptl[PSW]	This family of malware is a type of Trojan virus that spreads primarily through phishing emails, malicious download links, or bundled with software. Once it infects a user’s computer, it hides itself and steals sensitive user information—such as account credentials and bank card details—thereby compromising user privacy and security.
3	Trojan/Win64.CollectionStealer	This family of malware is a type of Trojan that gains access to a victim’s computer system by deceiving users or by carrying other malware. Once it infects a system, it runs in the background and covertly steals sensitive information, monitors user activity, and sends data to a remote server.
4	Trojan/Win64.CopperTube[Backdoor]	This family of malware is a type of Trojan that typically disguises itself as legitimate software or spreads through software vulnerabilities, malicious downloads, and other means. Its primary objectives are to steal sensitive information, establish persistent backdoors, and potentially participate in botnet activities, posing a serious threat to system security.
5	Trojan/Win32.SwimSnake	This family is a type of Trojan virus. It mainly spreads malicious programs through instant messaging software, malicious promotion on search engines, phishing emails, etc. It utilizes techniques such as “white plus black”, “memory execution Shellcode”, and “memory decryption Payload” to ultimately implant a remote control Trojan on the victim’s host.

Preprocessing Capabilities (partial) :

There are 31 types of shells that can be unpacked (accurate to the type), and 132 packages that can be disassembled, including all common packages and self-extracting packages.

Supporting Knowledge Output Capabilities:

For malware payloads, the integrated AVL SDK malware knowledge base encompasses 533 key behavioral patterns of ATT&CK, covering 171 ATT&CK technical tags with a coverage rate of 64.29%, basically covering all the statically detectable tags in the ATT&CK framework.

3. Be on Guard Against These Virus Families This Week

Over the past week, monitoring has revealed that the SwimSnake (Silver Fox) cybercrime group has primarily been spreading its activities through phishing websites that impersonate the official websites of legitimate software (such as Deepseek, Sogou Input Method, and Todesk). Its main attack methods are as follows:

1. The initial payload is written in the Go programming language and releases multiple sets of “white + black” files to mislead analysts, using “white + black” techniques to load malicious components.

2. It creates multiple scheduled tasks and registry startup entries to achieve persistence.

3. It deploys the Winos 4.0 remote control Trojan, which possesses process injection and remote control capabilities and can terminate multiple security software programs.

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.

Antiy AVL SDK is available in various versions such as traditional PC hosts, smart terminals, network traffic, IT application innovation systems, industrial systems, and unmanned systems. It provides threat detection capabilities for scenarios including host system and workload security, network traffic security, business flow security, email and file service security, etc. It fully supports various architectures such as X86, ARM, MIPS (including Cavium), RISC, and PowerPC, supports a variety of mainstream operating systems including domestic operating systems, Linux, and Windows, as well as real-time industrial operating systems like Vxwork. It also supports high-speed detection in backbone network scenarios.
