Enum HistAnomaly 

pub enum HistAnomaly {
    HistoryDisabled {
        command: String,
    },
    TimestampRegression {
        at: i64,
        previous: i64,

    RemoteExecPipe {
        command: String,
    },
    PwshEncodedCommand {
        command: String,

}

A graded shell-history anomaly.

Variants

HistoryDisabled

A surviving command that disables or clears history (the clearing itself was recorded). MITRE T1070.003.

Fields

command: String

TimestampRegression

A timestamped entry whose epoch precedes its predecessor’s — non-monotonic history, consistent with injected or back-dated entries.

Fields

at: i64

previous: i64

RemoteExecPipe

A download piped straight into a shell interpreter. MITRE T1059 / T1105.

Fields

command: String

PwshEncodedCommand

A PowerShell encoded/obfuscated command line. MITRE T1059.001 / T1027.

Fields

command: String

Implementations

impl HistAnomaly

pub fn code(&self) -> &'static str

The stable, published anomaly code (scheme-prefixed SCREAMING-KEBAB).

Trait Implementations

impl Clone for HistAnomaly

fn clone(&self) -> HistAnomaly

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HistAnomaly

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for HistAnomaly

impl Observation for HistAnomaly

fn severity(&self) -> Option<Severity>

Severity, or None if the analyzer deliberately does not grade this kind.

fn code(&self) -> &'static str

Stable, scheme-prefixed machine code.

fn category(&self) -> Category

Analytical lens; defaults to Category::from_code of Observation::code. Override when a code’s keyword classification is wrong.

fn note(&self) -> String

Human-readable, consistent-with note.

fn subjects(&self) -> Vec<SubjectRef>

Non-disk subjects this kind is about (default: none).

fn evidence(&self) -> Vec<Evidence>

Backing evidence rows (default: none).

fn mitre(&self) -> &'static [&'static str]

MITRE ATT&CK technique ids this kind is consistent with (default: none).

fn confidence(&self) -> Option<Confidence>

Heuristic confidence, if inferential (default: none).

fn to_finding(&self, source: Source) -> Finding

Assemble the canonical Finding from this kind and its producing source.

impl PartialEq for HistAnomaly

fn eq(&self, other: &HistAnomaly) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
