MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

The file is identified as malicious by ClamAV with the signature Doc.Downloader.Loda-7570590-0. It uses a remote template injection and external relationship, common for macro-based downloaders. The document body presents a list of parts, likely a lure to encourage users to enable macros, which would then trigger the download of a secondary payload from the embedded URL.

Heuristics 5

  • ClamAV: Doc.Downloader.Loda-7570590-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Loda-7570590-0
  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://covid19help.top/sharo.doc) — a common remote-template-injection vector used by Hancitor, Emotet and many phishing campaigns. Word can fetch and apply the remote template; macros in that template may execute depending on Office policy and trust state.
  • External relationship high OOXML_EXTERNAL_REL
    External target in word/_rels/settings.xml.rels: https://covid19help.top/sharo.doc
  • Macro/content-enable lure medium SE_ENABLE_LURE
    Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
