This paper explores the evolution of malicious payload delivery, specifically examining the trend of "bloated binaries"—files deliberately inflated to sizes like . While traditional malware was historically smaller than 1 MB to ensure rapid infection, modern attackers use larger file sizes to bypass legacy antivirus scanners and security sandboxes. 1. Introduction: The Psychology of the "Download/View" CTA

: Using the 107 MB of "legitimate" data to hide encrypted malicious commands that are extracted once the file is opened. 4. Conclusion and Defense

: It imitates the UI of legitimate cloud storage or PDF viewers like OneDrive . download/view now ( 107.48 MB )

: Many email gateways and basic antivirus solutions have a maximum file size limit (often 50 MB or 100 MB) for real-time scanning to prevent performance lag. A 107 MB file might be waved through without inspection.

The phrase "Download/View Now" is a social engineering tactic designed to create urgency. The parenthetical file size (107.48 MB) serves two purposes: This paper explores the evolution of malicious payload

Paper Title: The 100MB Threshold: Strategic File Inflation in Modern Malware Delivery

: Attackers often "pad" small malicious code with millions of "zeros" (null bytes) to reach a specific target size without changing the code's function. 3. Common Payload Types at This Scale Introduction: The Psychology of the "Download/View" CTA :

: Providing a specific decimal size makes the file appear technical and "real" to the average user. 2. Technical Evasion: Why ~107 MB?
