## Indicators of Compromise (IOCs)

> **Note:** All network and host IOCs MUST be defanged before inclusion in this report.
> Defanging rules: URLs use `hxxp`/`hxxps`; domains bracket the dot before the TLD (`evil[.]com`);
> IP addresses bracket each dot (`192[.]168[.]1[.]1`); email addresses replace `@` with `[@]`.

### File Indicators

## Detection Rules

### YARA Rule

```yara
rule [RuleName]_[MalwareFamily] {
    meta:
        description = "[Brief description]"
        author = "[Your name]"
        date = "[Date]"
        hash = "[Sample SHA256]"

    strings:
        $string1 = "[hex or text pattern]" [modifiers]
        $string2 = "[hex or text pattern]" [modifiers]
        $api1 = "[API call pattern]"

    condition:
        [Condition logic - e.g., uint16(0) == 0x5A4D and filesize < 500KB and all of ($string*)]
}
```

### Sigma Rule (Optional - for behavioral detection)
