Malicious
OfferCore bundler/adware identified by 13 engines including tier-1 consensus; process injection and direct-IP C2 observed; 4 prior imphash matches verdicted malicious.
c186526bba36a0ea2a…921836b794The reasoning behind this verdict
The MT AI Engine weighs every signal from this scan — antivirus detections, sandbox behaviour, code signing, prevalence and historical matches — to reach a single, evidence-based verdict.
The evidence converges on OfferCore, a PUA/bundler family. While tier1FamilyConsensus.strong is false (only 1 engine explicitly naming 'bundler'), the malicious detections are NOT generic heuristics — 10 distinct engines name 'OfferCore' or 'Bundler.OfferCore' specifically, indicating a recognized family rather than a false positive. The RAG data is decisive: 4 of 5 similar-hash matches (same imphash, different signers) were verdicted malicious with ai:malware_family_offercore, confirming the family identification. Behaviour analysis shows T1055 process injection and 15 direct-IP contacts with zero DNS queries, a classic bundler C2 pattern. The signer 'Infivora' has no history in our database, but this does not override the family consensus and behaviour signals. Prevalence is rare_new, consistent with a freshly repackaged variant.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

Block and quarantine this file. OfferCore is a confirmed bundler/adware family with consistent multi-engine detection and offensive runtime behaviour. Do not allow execution on any system.
What this file does
What it attempted when executed in an isolated sandbox
Hides inside another running program to evade antivirus.
Talks to a remote server to take commands or send out your data.
Obfuscates or packs its code to avoid detection.
Deletes traces of itself to cover its tracks.
Collects details about your system.
Loads extra code modules while running.
Translated from the file's technical behaviour during analysis. It never ran on your device.
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.
What to do now
This file is dangerous. Treat it as harmful and remove it.
Don't open or run this file. Delete it from your Downloads (or wherever you saved it), then empty the Recycle Bin.
If you already opened it, disconnect from the internet and run a full scan with your antivirus — Windows Security (built into Windows) works fine.
If you typed any passwords while it was open, change them from a device you trust.
In future, only download software from the official website or an official app store.

YARA & heuristic rule matches
A researcher-curated or high-severity heuristic rule matched this sample. These rules target specific malware families and are near-definitive.
MITRE T1055 (Process Injection) observed — CreateRemoteThread / APC / reflective-DLL injection. The payload is being smuggled into a legitimate process to bypass AV hooks.
Evidence"C:\Users\<USER>\Desktop\Mob Factory_JZpgL-7.exe"Sample contacted 15 external IP address(es) and zero domains. Benign software virtually always uses DNS; no-DNS direct-IP C2 is a strong malware indicator because it bypasses reputation systems and dodges domain-based blocklists.

How widely this file has been seen
Barely seen in the wild and first surfaced recently. This is the footprint of targeted malware the AV industry hasn't signatured yet — extra scrutiny is warranted.

Safety FAQ
Common questions about Mob Factory_JZpgL-7.exe, answered from the scan data above.
- Yes — Mob Factory_JZpgL-7.exe is malicious, so do not run it, and delete it. 13 of 74 antivirus engines flag it (family: offercore). It behaves as adware or a potentially unwanted program (PUA) — not always destructive, but it bundles ads, trackers, or unwanted changes you didn't ask for. If you've already run it, see the removal and recovery steps below.
- Mob Factory_JZpgL-7.exe is a Windows executable program, about 15.4 MB. Our analysis identifies it as malicious (family: offercore) — adware or a potentially unwanted program (PUA) — not always destructive, but it bundles ads, trackers, or unwanted changes you didn't ask for. Because a file's name and icon can be faked, the safest way to identify it is by its cryptographic hash (below), not its filename.
- 13 of 74 antivirus engines flagged Mob Factory_JZpgL-7.exe, 13 of them as outright malicious. A detection rate at this level is a reliable signal that the file is dangerous.
- Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
- To remove Mob Factory_JZpgL-7.exe: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Delete the original Mob Factory_JZpgL-7.exe file and empty the Recycle Bin/Trash. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
- Mob Factory_JZpgL-7.exe is classified as adware or a potentially unwanted program (PUA) — not always destructive, but it bundles ads, trackers, or unwanted changes you didn't ask for. Engines attribute it to the offercore family. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
- Yes — Mob Factory_JZpgL-7.exe carries a valid digital signature from Infivora, which confirms the file hasn't been tampered with since that publisher signed it. A valid signature is a positive signal, but note that malware is occasionally signed with stolen or abused certificates, so it isn't proof of safety on its own.
- The SHA-256 hash of Mob Factory_JZpgL-7.exe is c186526bba36a0ea2aaf9df79fe999a8c7e1a1e477e3c658de776b921836b794, and its MD5 is a35c246b9b370cb452544f2af3ee2bed. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
- This report reflects the scan run on July 12, 2026. Because a file's hash never changes, the identity of Mob Factory_JZpgL-7.exe is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
