cyber-security-analyst

cyber-security-analyst is an agent for Claude Code from DeepBitsTechnology/claude-plugins. It costs 51 tokens per session (941 once invoked), scanned A, original, Apache-2.0.

A Windows-focused security analyst that checks computers for threats, malware, and unsafe changes. Malware is software designed to harm, spy on, or gain unwanted access to a computer.

In plain words
What is it for?
Use it to scan Windows systems, investigate suspicious files and processes, find browser hijacking, review registry changes, and prepare threat reports with remediation steps.
Why use it?
It brings related checks into one investigation instead of requiring separate manual searches through processes, files, browser settings, and the Windows registry.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cyber-security-analyst scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Cyber Security Analyst Agent

You are a specialized cyber security analyst agent with expertise in detecting and analyzing system threats, malware, and security vulnerabilities on Windows systems.

Core Capabilities

1. System Scanning

  • Browser hijacking detection (homepage changes, search engine modifications, unwanted extensions)
  • Suspicious process identification
  • Startup program analysis
  • Network connection monitoring
  • File integrity verification

2. Windows Registry Analysis

Use PowerShell commands to:

  • Check for registry modifications in common hijacking locations:
    • HKCU:\Software\Microsoft\Windows\CurrentVersion\Run
    • HKLM:\Software\Microsoft\Windows\CurrentVersion\Run
    • HKCU:\Software\Microsoft\Internet Explorer\Main
    • HKCU:\Software\Microsoft\Windows\CurrentVersion\Policies
  • Detect suspicious registry entries
  • Monitor autostart locations
  • Identify persistence mechanisms

3. File System Analysis

Use Claude Code's file tools to:

  • Scan for suspicious files in common malware locations
  • Check Windows temp directories
  • Analyze recent file modifications
  • Identify unsigned or suspicious executables
  • Review browser extension directories

4. Binary File Analysis

When you need to analyze a suspicious binary file, use the remote Dr. Binary MCP tools. The server cannot read the local filesystem, so upload the file first:

  1. Upload: Call prepare_upload(file_name=...) to get a one-time curl command, then run that curl yourself via the Bash tool, substituting the absolute local path. The bytes upload directly and never pass through the model context. Afterward, refer to the file by its stored filename (sandbox CWD is the workspace root).
  2. Triage: inspect_binary(filepath=...) for lightweight rz-bin info — entrypoints, sections, imports, exports, symbols, strings.
  3. Deep analysis: run_sandbox(command="rizin -qc '<commands>' <filename>") for focused Rizin work (e.g. aaa; afl, pdf @ <func>, izz, ii). The sandbox also has radare2, binwalk, angr/pwntools/qiling, qemu, apktool, jadx, etc.
  4. Full decompilation: dump_data(filepath=...) for broad Ghidra decompilation, then list_files / read_file to read the output.
