Shipup

Overview

ShipUp (tracked across threat intelligence feeds as Adware:Win32/ShipUp, Trojan.Win32.ShipUp, and Win32/Shipup) is a deceptive adware engine and background payload downloader analyzed by Microsoft Defender and Kaspersky. Spreading via bundled software installers, cracked software portals, and deceptive online advertisements, ShipUp installs background monitoring components that track user web browsing behavior, collect system telemetry, and inject unwanted commercial pop-up advertisements. In addition to advertising injection, ShipUp functions as a persistent secondary downloader, maintaining contact with remote command-and-control servers to retrieve and deploy auxiliary potentially unwanted applications (PUAs) and toolbars. It establishes persistence by writing startup entries to HKCU\Software\Microsoft\Windows\CurrentVersion\Run and creating scheduled maintenance jobs via Windows Task Scheduler.

MITRE D3FEND™ Defensive Countermeasures

Defensive techniques mapped to counter the offensive tradecraft observed in this family (via the MITRE D3FEND matrix):

Indicators of Compromise

Public indicators drawn from CISA advisories and vendor reporting. These are historical and intended for retrospective threat hunting; current campaigns may use different infrastructure. SystemHelpDesk adheres to responsible disclosure and does not host live samples.

File hashes (SHA-256, sample)

Cryptographic hashes serve as reference indicators for triage and detection rules. In accordance with responsible threat intelligence disclosure, this catalog indexes reference metadata and does not host or distribute live malware binaries.

Delivery vectors

• Software bundlers packaged with cracked software and media players
• Deceptive pop-up advertisements prompting for software updates

Persistence mechanisms

• HKCU\Software\Microsoft\Windows\CurrentVersion\Run\ShipUpService
• Scheduled Task created via schtasks /create /tn 'ShipUpTask' /tr '%ProgramFiles%\ShipUp\shipup.exe'

Tiered Detection Rules (Cisco CAIRN Model)

Modern threat detection requires multi-layered rule engineering. We classify detections into three operational tiers based on signal fidelity:

rule MALWARE_WIN_SHIPUP_T1_ARTIFACT {
    meta:
        description = "Tier 1 Primitive Artifact: Raw string matches for Shipup"
        tier = "T1 - Primitive Artifact"
        confidence = "Low-Medium (Fast Triage)"
        author = "SystemHelpdesk Threat Research Desk"
        date = "2026-10-14"
    strings:
        $s1 = "shipup" ascii wide nocase
        $s2 = "adware:win32/shipup" ascii wide nocase
        $s3 = "trojan.win32.shipup" ascii wide nocase
        $s4 = "win32/shipup" ascii wide nocase
        $s5 = "pup.optional.shipup" ascii wide nocase
        $s6 = "shipup.downloader" ascii wide nocase
    condition:
        uint16(0) == 0x5a4d and any of them
}

Containment & Response Steps

Ordered checklist for responders. Adapt to your environment and engage professional support for active incidents.

1. Isolate the endpoint to prevent background downloading of secondary PUA bundles.
2. Uninstall ShipUp and any recently added bundled software via Windows Control Panel.
3. Delete scheduled tasks matching 'ShipUpUpdate' or 'ShipUpMaintenance'.
4. Run an enterprise antimalware scan to eliminate dropped secondary adware binaries.

What to Avoid

Common mistakes during response to this family that can destroy evidence, spread the infection, or worsen recovery.

1. Do not allow users to execute software setups downloaded from unauthorized third-party file repositories.
2. Avoid ignoring persistent adware detections; downloader capabilities allow operators to shift to ransomware distribution.
