GMDSOFT Tech Letter Vol19.App Artifact Analysis: Text Input Records

Why It Matters

Recovering keyboard logs turns deleted or encrypted chats into actionable evidence, reshaping digital investigations across law‑enforcement and corporate security.

Key Takeaways

• Keyboard databases retain typed text after message deletion
• MD‑RED extracts unsent and converted input logs
• Supports multi‑step languages like Japanese Romaji‑Kanji conversion
• Reveals user habits via predictive text patterns
• Enhances investigations where encrypted apps are used

Pulse Analysis

The proliferation of end‑to‑end encrypted messengers and the routine use of the delete function have left investigators with fewer traditional data sources. While message bodies disappear, the underlying keyboard applications continue to log every keystroke, candidate words, and language conversion steps. This hidden layer, long overlooked, now offers a forensic foothold that can reconstruct communication intent even after the user believes the evidence is gone. Understanding these artifacts is becoming a prerequisite for modern digital investigations.

GMDSOFT’s MD‑RED engine targets exactly that hidden layer. By parsing the SQLite databases maintained by iOS and Android keyboard apps, the tool extracts raw input strings, predictive suggestions, and the full Romaji‑to‑Kanji conversion path used in Japanese typing. It can surface text that never left the input field, reveal partially typed sentences, and map a user’s personalized vocabulary. The analysis is language‑agnostic but shines with multi‑step scripts, where each conversion stage leaves a distinct timestamped record, enabling investigators to piece together a timeline of intent.

The practical payoff is immediate. Law‑enforcement agencies can link a suspect to illicit content without needing the original message, while corporate security teams gain insight into insider threats that rely on self‑destructing chats. As privacy‑by‑design features become standard, tools like MD‑RED will differentiate forensic service providers and drive new market demand for specialized artifact extraction. Early adoption not only improves case outcomes but also positions organizations at the forefront of the evolving digital evidence landscape.
