Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
21 of 75 engines detect the file, including 7 tier-1 engines naming OfferCore variants. The signer has zero clean history and every similar imphash sample was previously ruled malicious.
The combination of tier-1 detections, a brand-new rare submission, and a signer whose two prior samples were both malicious outweighs the absence of sandbox or network telemetry. Similar-hash RAG confirms the same OfferCore family verdict on matching imphashes. No test-file or trusted-publisher signals exist to offset the risk.
What We Detected
21 of 75 engines flag the sample; 7 tier-1 engines label it OfferCore or InstallCore variants. The executable is signed by 'Infivora', a publisher with 0/2 clean historical samples.
Threat Behavior
OfferCore bundles install additional adware or potentially unwanted programs. The file is 0 days old, rare, and shares its imphash with previously confirmed OfferCore droppers.
What To Do Now
Do not execute the file. Keep endpoint protection enabled and delete the installer. If already run, review installed programs for unexpected OfferCore components.
- 7 tier-1 engines flag OfferCore
- Signer history 0/2 clean
- rare_new prevalence, 0 days old
- 5/5 similar imphash samples malicious
Treat as malicious OfferCore adware/bundler; avoid execution and remove the file.

Threat context
How bundlers & adware work
This is a bundler — a real-looking installer that hides extra software inside. When you run it, it quietly installs things you never asked for: ad injectors, browser toolbars, fake 'PC cleaner' apps, or even more bundlers. The people behind it get paid for every unwanted app they sneak on.
Bottom line:It's not usually built to destroy files, but it slows your PC, floods it with ads, and can be a real pain to fully remove.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Barely seen in the wild and first surfaced recently. 21 antivirus detections make that low prevalence materially relevant, but rarity alone is not proof of malware.
