## 1\. Executive summary

Infoblox has disclosed a threat actor dubbed "Lurking Lizard" operating an end-to-end malicious residential proxy business using trojanized installers — including a fake 7-Zip installer hosted on 7zip\[.\]com — to covertly recruit victim devices as proxy nodes. Attribution to a China-based actor is unconfirmed: "Lurking Lizard" has no MITRE ATT&CK profile, and the assessment rests on WHOIS analysis and infrastructure fingerprinting from a single vendor (Infoblox). The campaign dates to at least August 2022 and uses more than 230 lookalike domains, impersonating major proxy providers (IPIDEA, SmartProxy/Decodo, IP Royal, 911Proxy) and distributing lures for 7-Zip, WhatsApp, TikTok/YouTube downloaders, and WireVPN. For EMEA financial services, the primary risk is corporate endpoints being silently enrolled as proxy exit nodes, exposing the organisation's IP space to third-party criminal traffic and potential reputational and legal liability.

## 3\. Technical analysis & attack chain

### Confirmed attack chain

1. **Domain acquisition and infrastructure setup.** The actor uses "drop-catching" — acquiring expired domains to inherit their accumulated history and legitimacy. The actor has registered 230+ lookalike domains impersonating legitimate proxy providers and software projects. In some cases, the actor exploits incorrectly referenced domain names (e.g., victims typing "7zip\[.\]com" instead of the official "7-zip\[.\]org").
2. **Victim acquisition.** Victims are directed to malicious installers through three channels: tutorial content, search-driven discovery, and lookalike domains. Fake "independent" review sites drive traffic to the actor's scam storefronts.
3. **Trojanized installer delivery.** The 7-Zip campaign delivered a trojanized 7-Zip installer from "7zip\[.\]com." Additional lures served from the same infrastructure include fake installers for WhatsApp, tools falsely claiming to be TikTok and YouTube downloaders, and WireVPN.
4. **IPLogger beacon.** Samples tied to the 7-Zip campaign contain an embedded IPLogger URL: `iplogger[.]com/mnWD`. This URL links the 7-Zip campaign to the broader infrastructure serving all the above-mentioned lures.
5. **Proxy node enrolment.** Compromised desktop devices are converted into proxy exit nodes that funnel third-party traffic through victims' devices. The actor then monetizes the proxy pool through lookalike proxy service brands.
6. **Monetization.** The proxy pool is sold through lookalike brands impersonating IPIDEA, SmartProxy (now Decodo), IP Royal, and 911Proxy. Proxyway found 773,087 unique IP addresses linked to SmartProxy also present in a publicly available IPIDEA IP dataset of 16,192,293 unique IPs, suggesting SmartProxy either resells IPIDEA's infrastructure or uses it as a significant IP source.
7. **Mobile expansion.** The WireVPN branding represents the latest evolution, targeting Android, macOS, and Windows. An Android app called "wirevpn - Fast Unlimited Proxy," developed by UK-based "WEILAI NETWORK TECHNOLOGY CO., LIMITED," has amassed 1M+ downloads. It is unclear whether these downloads are organic, and it is unclear whether the same proxy exit-node functionality is present in the mobile applications or limited to desktop.

**Attribution caveat:** "Lurking Lizard" has no MITRE ATT&CK profile; attribution is unconfirmed. The China-based assessment rests on WHOIS analysis and infrastructure fingerprinting from Infoblox alone — single-sourced; verify before enforcement.

**Technical gaps in source material:** The source does not provide specific malware family names, file hashes, C2 protocols, persistence mechanisms, registry keys, file paths beyond the installer domain, or command-line artefacts. The exact mechanism by which the trojanized installer enrols devices as proxy nodes is not described. No CVE is referenced.

## 4\. Mitigation & containment

### P1 — Within 24 hours

- **Block known malicious domains** at DNS resolver and web proxy: `7zip[.]com`, `iplogger[.]com` (or specifically the path `iplogger[.]com/mnWD`). Note: `iplogger[.]com` is a legitimate IP-logging service abused as infrastructure; consider blocking the specific URL path rather than the entire domain if business use exists.
- **Block the Android application** "wirevpn - Fast Unlimited Proxy" (developer: WEILAI NETWORK TECHNOLOGY CO., LIMITED) on all MDM-enrolled devices.
- **Search endpoint telemetry** for historical connections to `7zip[.]com` and `iplogger[.]com/mnWD` (last 12 months minimum, given campaign dates to August 2022).
- **Alert on outbound proxy traffic** from workstations that should not be running proxy services — unexpected listening ports, unusual outbound connection patterns consistent with proxy relay.

### P2 — Within 72 hours

- **Application allow-listing / software download policy:** Block user-initiated downloads of executable installers from non-approved domains. Ensure the official 7-Zip domain is documented as `7-zip[.]org` in user guidance and IT documentation.
- **Review DNS logs** for any of the 230+ lookalike domains. The source does not enumerate them all; request the full list from Infoblox if available, or hunt for domains impersonating: IPIDEA, SmartProxy, Decodo, IP Royal, 911Proxy, WireVPN.
- **EDR hunt:** Search for processes named or matching `wirevpn`, and any 7-Zip installer binaries not signed by the legitimate 7-Zip publisher or downloaded from `7-zip[.]org`.
- **Network egress review:** Identify any internal IPs appearing in residential proxy datasets. Cross-reference against known proxy IP feeds.

### P3 — Within 7 days

- **User awareness:** Brief staff on the typosquatting vector (7zip\[.\]com vs. 7-zip\[.\]org) and the broader pattern of trojanized installers promoted through tutorial content and search results.
- **Software sourcing controls:** Update software procurement and download procedures to require verification of publisher domains. Add the drop-catching technique to threat-modelling for software supply chain.
- **Mobile app governance:** Review the mobile application allow-list and block apps from developer "WEILAI NETWORK TECHNOLOGY CO., LIMITED" pending verification.

## 8\. Adverse Trace position

This is a **medium-severity** advisory for EMEA financial services. No CVE is in scope and no CISA-KEV exploitation is referenced. The core risk is not direct data theft or ransomware but silent enrolment of corporate endpoints as residential proxy exit nodes — exposing the organisation's IP addresses to third-party criminal traffic, with attendant reputational, legal, and potential regulatory consequences. Attribution to "Lurking Lizard" as a China-based actor is unconfirmed (no MITRE ATT&CK profile; single-sourced to Infoblox WHOIS and infrastructure fingerprinting). The campaign's longevity (since August 2022), scale (230+ domains, 16M+ IPs in the proxy pool), and use of drop-catching and lookalike domains indicate a mature, well-resourced operation. We are treating the IOCs as actionable but note the full domain list is not publicly enumerated in the source — clients should request it directly from Infoblox. Adverse Trace will update this advisory if additional IOCs, malware family details, or the full lookalike domain list become available.
