不同类型恶意软件术语的明确界定标准及分类可行性咨询

Great question—this ambiguity around cybersecurity terms is something even seasoned professionals grapple with from time to time. Let’s tackle your two points clearly:

1. Are there formal standards defining these terms? #

Yes, several authoritative bodies have established clear definitions to standardize terminology, though informal usage can still vary across contexts:

• NIST (National Institute of Standards and Technology)：In documents like SP 800-83, malware is defined as a broad umbrella term covering any program or code designed to perform unauthorized, harmful actions on a system. This explicitly includes subcategories like viruses, worms, trojans, rootkits, ransomware, and spyware.
• ISO/IEC 27000 Series：This set of information security standards also frames malware as a general category, with specific definitions for each subtype based on their behavior and propagation methods.
• Keep in mind: In casual conversations or some vendor documentation, you might encounter looser usage (e.g., someone calling all malware "viruses"), but the authoritative standards maintain clear hierarchical boundaries.

2. Can malware be split into two categories: exploits and executables? #

First, a critical clarification: Exploits are not a type of malware. Exploits are tools or snippets of code that take advantage of software vulnerabilities to gain access to a system or execute actions. Malware is often deployed using exploits, but they’re distinct concepts—exploits are the "key" to unlock a system, while malware is the harmful program that runs once inside.

If you’re looking to categorize malware itself, a strict binary split (like "executables" vs. anything else) is overly simplistic and misses key nuances. Most practical classifications of malware are based on behavior or propagation:

• Self-propagating malware: Includes viruses (require a host file to replicate) and worms (can spread independently across networks).
• Non-self-propagating malware: Includes trojans (disguised as legitimate software), ransomware (encrypts data for ransom), rootkits (hide their presence on a system), and spyware (collects user data without consent).

That said, if you absolutely need a high-level binary split, grouping malware into self-sustaining (can spread on its own) and user-dependent (requires user action to execute, like opening a malicious attachment) is more meaningful than tying it to exploits or executables.
