1.Weekly Update                           

Statistical period: June 13, 2026 ~ June 19, 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 19 new detectable malware families, 5,717 new detectable malicious code variants, and 23,031 new detection rules.

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

Number	Virus Name	Virus Description
1	Trojan/Win32.PixyNetLoader	This family is a type of Trojan that primarily infiltrates computer systems through Trojan programs, monitoring users’ keyboard inputs and screen activities to record sensitive information such as account names and passwords.
2	Trojan/MSIL.SecoStealer	This family is also a Trojan that mainly spreads and infects by exploiting system vulnerabilities. The virus disguises itself as legitimate software or hides within cracked programs and pirated software, tricking users into downloading and executing it, thereby stealing sensitive data including bank accounts, passwords, personal identification information, and other critical details.
3	Trojan/Win64.HydraWorm[Backdoor]	This family is a type of Trojan that infiltrates victims’ computer systems by deceiving users or carrying other malicious software. Once infected, it runs in the background, covertly stealing sensitive information, monitoring user activities, and transmitting data to remote servers.
4	Trojan/MSIL.Dominiko[Ransom]	This family is a type of Trojan typically spread through phishing emails, malicious downloads, or vulnerability exploitation. Upon infection, the malware encrypts users’ files and demands ransom payments for decryption keys, posing a serious threat to computer systems.
5	Trojan.HTML.Phish	This family is a type of Trojan designed primarily to severely compromise the availability, integrity, and confidentiality of operating systems, or to achieve similar effects upon execution. Its associated samples are HTML files, often containing embedded JavaScript code, which mainly exploit browser vulnerabilities to carry out various types of cyberattacks.

Supporting Knowledge Output Capabilities:

For malware payloads, the AVL SDK and the accompanying malware knowledge base can output 533 key behavior mapping tags, covering 171 categories of ATT&CK tactical 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, we have detected an increasing number of fraudulent activities carried out by criminal organizations targeting global football fans for the 2026 FIFA World Cup. These activities involve counterfeiting fake tickets, recruiting and live-streaming on websites. Criminals are using domain name registration techniques to create domain names that are slightly different in spelling or have different suffixes. These domain names closely resemble legitimate websites, which collect personal information (PII), including names, home addresses, phone numbers, email addresses, bank information, and payment card details. Using this personal information, they carry out financial fraud and sell counterfeit products and services. The main fraudulent activities include FIFA ticket fraud, false package sales, false job postings, and other forms of financial fraud.

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.
