+16
Runtime behavior
  • Dropped an executable to disk
  • 1 Sigma rule match(es): Uncommon Child Process Of Conhost.EXE

Model reading

Measured SUSPICIOUS46 of 100

Evidence ledger above, row by row. Published verdict rests on this column and on nothing to its right.

Model reads it asadvisory, no points NOT ASSESSEDnot shown on this page

Reads this report's derived findings, never the sample itself.

A model reading exists for this scan and is shown to the submitter and to staff only. It is a second opinion about evidence the score already priced, it is worth no points, and on a public page it would stand beside the verdict with no grounding a stranger could check.

Withheld: 5 rules fired and were not reported above

These rules matched this sample, and they also match this much of known-clean software (measured over 1145 signed Windows and third-party binaries). A rule that fires on most clean files cannot move a verdict, so it is held back unless the detonation confirms the behaviour. They are listed because a count that shrinks without saying so is not a count an analyst can check.

Dynamic API resolution (obfuscation) fires on 65% of benign software
Resolves APIs dynamically (LoadLibrary + GetProcAddress) fires on 49% of benign software
Reads its own startup info (parent/desktop check) fires on 36% of benign software

What the tests returned

5 tests

Each test this run performed and what it returned. A test that was not performed says so rather than reading as a negative result.

TestResult
Persistence mechanismsnone established at runtime
Cross-process injectionnone observed
Network connectionsthe capture came up and attributed no outbound connection; this run had no route out, so none could have succeeded in any case
Known-malicious hash (reputation sources)no source reported this file
Local anti-virus enginereported no detection

Absence of an observation is not proof of absence - see Coverage for what this run could and could not test.

Arguing against malice

  • The local anti-virus engine reported no detection.
  • No reputation source reported this file as malicious.

How much weight this carries

Confirmed. Independent external evidence, or the same behaviour seen by more than one analysis layer. The one fact that decided it: several independent runtime observations.

Instrument coverage

0 of 4 measured

What this run was able to observe, as the run itself recorded it. A layer that did not run makes an empty result a fact about the sandbox rather than about the sample.

LayerRanWhat that means
Runtime anti-analysis watch not measured Not measured. No in-process monitor reported in on this run, so the runtime anti-debug and anti-VM calls were never watched and an empty list is not a finding about the sample.
API call sequence not measured Not measured. No anti-analysis hook armed on this run, so this sequence carries interpreter spawns only and an empty one does not mean the sample called no APIs.
Explicit module loads not measured Not measured. No in-process monitor reported in on this run, so no module load could be recorded and an empty list does not mean the sample loaded nothing.
Network capture not on this plan Not included on this scan's plan.
Live kernel introspection not measured Not measured. This run did not ask for the memory-dump option, which is what starts the introspection loop.

This lists the layers this run recorded for itself. A layer that is not listed was not recorded either way, so its absence here is not a result.

Antivirus engine

no signature matched signature set 28160 - 3.6M signatures

Nothing in the signature set below matched this file. That is one engine's negative answer against one signature set on one day, and it is not a verdict. A signature engine only recognises what has already been named and published, so a file nobody has named yet scans exactly like a file that is harmless. What this file does when it runs is the stronger evidence; read the behaviour sections for that.

A negative answer is only as good as the signature set that gave it, so the set is recorded with the result and the result can be reproduced against it.

Local ML assessment

99.0 of 100 8 strongest of 2568 features

A gradient-boosted model running entirely on this host scored this file 99.0 of 100 on structure alone: its headers, sections, imports, strings and signature. The file was not executed and nothing about it left this machine.

Read this as corroboration and not as a verdict. Measured across this corpus the model separates signed software from unsigned software more sharply than malicious from benign, so it is charged at most 15 of 100 verdict points and only on top of evidence this report measured for itself. The eight features below are the ones that moved it furthest.

Structural featureWhat it meansPushesWeight
image flag dll Image flag: a library rather than a program towards malicious +0.6885
parser warning: Suspicious flags set for section... Header defect reported by the parse: Suspicious flags set for section... (0) towards benign -0.5362
section entropy .rsrc Byte randomness of section .rsrc towards malicious +0.4350
coff.timestamp Build timestamp recorded in the header (1777280384) towards malicious +0.4290
feature column 2478 When a timestamp authority countersigned the signature towards malicious +0.3833
resource directory size Size of the resource table (190880) towards benign -0.3173
security directory size Size of the security table (0) towards malicious +0.3100
feature column 993 Byte randomness of the data appended after the last section towards benign -0.2736

A weight is a log-odds nudge away from the model's own baseline, not a percentage point. Where a feature names a section, an import or a build id, the number beside it is the model's own hashed cell for that name rather than a measurement of the file: two names can share one cell and the sign comes from the hash, so no number is shown for those rows.

Family configuration search

Incomplete

1 of this platform's 69 family parsers could not decode this file, and none produced a configuration. A parser that carries no signature of its own is handed every file, and every parser that has ever failed here is one of those, so a failure is usually a decoder meeting a family it was not written for rather than a reading about this sample. Where the two numbers below differ, a signature did match and its decoder then returned nothing. The absence of a configuration is not evidence that none is present.

Statically visible checks (RDTSC/CPUID/red-pill instructions, anti-debug APIs) plus runtime evasion signals. Instruction-level interception at runtime requires hypervisor introspection (VMI).

WMI activity

3 classes

WMI classes the sample queried, captured from the WMI-Activity trace and attributed to the sample process tree. Hardware/identity classes also surface as VM-detection checks above.

Win32_ComputerSystemWin32_BIOSWin32_PNPEntity

WMI method invocations

1 call

Methods the sample invoked through WMI, with their arguments. A process created this way is spawned by the WMI provider host, so the operating system records no parent link back to the sample - the caller is named by the WMI-Activity trace and the argument is captured in the calling process itself.

Connect pid 5924

Command lines, unwrapped

5 read

5 captured texts were read and unwrapped locally. No address was recovered from any of them, and none of them was hiding its own contents behind an encoding or a format string. This is a result, not a gap.

Network activity

The network section is a paid-plan layer: the DNS the sample resolved, the connections it opened, the TLS it negotiated, and the rule engine's reading of the capture.

This run was captured, and what it captured is on a paid plan rather than absent. An internet-connected detonation is the same plan, so a paid run also shows what the sample reached rather than only what it tried.

Dropped payload analysis

not examined

The run recorded 4 payload writes and the guest returned no payload capture, so no bytes were kept and none of these files was examined. Their paths are listed above. Read this as a gap in the evidence: nothing here says those payloads were harmless.

External reputation was not produced for this scan. Threat intelligence enrichment is a paid-plan layer: every extracted indicator - hashes, addresses, hostnames - is checked against the external reputation services. Our own ingested feeds ran on this scan and every result below is theirs. Adding the paid layer adds an external reputation verdict on each indicator, so VirusTotal, MalwareBazaar and filescan.io are listed below as not checked. See plans.

AI analysis

The AI layer is a paid-plan feature. It reads what the other layers produced - the behaviour summary, the call sequence, the indicator list - and writes the narrative and the kill-chain walkthrough.

Nothing is being withheld. This layer did not run for this scan, so there is no result stored behind the lock.

Export & download

/s/2894

Structured exports for your SIEM/TIP - ATT&CK Navigator layer, STIX 2.1 bundle, MISP event and a defanged IOC list - are free on every report. The packet capture follows this scan's plan, because a capture is the rawest network output this platform produces.

AI analysis report

An enterprise report with an AI-written executive summary, threat assessment, kill chain, and recommendations, plus the derived evidence (verdict, MITRE ATT&CK, network, file modifications, dropped files, IOCs) and screenshots. The AI narrative is built from derived analysis data only, so the raw sample never leaves the host (no-upload and AI-boundary preserved).
