MITRE ATT&CK

T1566.001 Spearphishing Attachment

This PDF document employs a lure related to game hacks and free in-game currency, specifically targeting Roblox and Coin Master players. It contains invisible links that redirect to CAPTCHA-themed pages, a common tactic to obscure malicious downloads. The ML classifier strongly indicated maliciousness, and the presence of multiple URLs associated with game exploits suggests a downloader or phishing campaign.

Heuristics 4

Invisible PDF links to CAPTCHA-themed web lure high PDF_CAPTCHA_LINK_LURE

PDF contains invisible clickable link annotations that point to a CAPTCHA/capcha-themed web path. This is a common phishing and ClickFix-style routing pattern: the PDF itself is inert, while the linked page performs the credential prompt or fake verification.
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
External URI info PDF_URI

PDF contains an external URL action
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.
