Building kali-cli: Python CLI Tool with Argparse

Just finished building my first custom Port Scanner using Python! While tools like Nmap exist, I wanted to go "under the hood" to truly understand how TCP connections and the three-way handshake work at the socket level. Key features i implemented: TCP Connect Scanning: Using the socket library to identify open/closed ports. Bulk Processing: Ability to import target hosts and port lists from text files. User Experience: Added a CLI menu with color-coded results for better readability. Building this helped me understand network timeouts, error handling in Python, and the importance of securing open ports to reduce attack surfaces.

🔐 Built an Interactive Password Strength Checker in Python! Just coded a complete password validation system with: ✅ Real-time strength analysis ✅ Detailed improvement suggestions ✅ Interactive retry system ✅ User-friendly interface ✅ Continuous checking option 🔗 GitHub Repository: https://lnkd.in/dWVSKtmr ✨ Interactive Features: 1. Enter password → Get instant analysis 2. Choose to improve or continue 3. Get specific tips for weak passwords 4. Enter improved version 5. Continue or exit anytime 🔧 Code Logic: python while True: password = input("Enter password: ") score, missing = check_strength(password) if not strong: choice = input("Improve? (yes/no/exit): ") if choice == "yes": show_tips() elif choice == "exit": break #Python #CyberSecurity #Coding #Programming #PasswordSecurity #LearnPython #CodingTips #LearnPython #Beginner #PythonTips #Developer #CodeNewbie #ProgrammingTips #PythonProgramming #SoftwareDevelopment #Tech #ComputerScience #DataScience #WebDevelopment #Day13

“We audited a Python app storing passwords in plain text - in 2025.” Security failures rarely come from Python. They come from missing processes, skipped reviews, and rushed delivery. In our newest post, we share: 🔹 the 3 Python security pitfalls we see most often 🔹 how linting, OWASP scanning, and review gates prevent them 🔹 why security must be part of your CI, not an afterthought Full article 👇 🔗 https://lnkd.in/gGMZhdrk #PythonDevelopment #Security #Django #FastAPI #OWASP #ARIS

🚨Medium Risk Vulnerability Alert🚨 Product: Bokeh, a popular interactive visualization library in Python has a vulnerability (CVE-2026-21883) that could allow an attacker to interact with the Bokeh server on behalf of the victim, potentially accessing sensitive data, or modifying visualizations. This issue is related to Broken Access Control, a common API security issue. It's crucial to always keep your software up-to-date to avoid such risks. Stay safe! #Bokeh #Python #APIsecurity #OWASP #CVE202621883 https://lnkd.in/dnJbHwqH

🚨 High Risk Alert! CVE-2025-68664, a critical serialization injection vulnerability has been discovered in the LangChain Core Python package. This vulnerability allows attackers to inject malicious lc markers, posing a serious risk to API security. Stay vigilant and ensure your systems are updated. #LangChain #Python #APIsecurity #OWASP #CVE202568664 https://lnkd.in/gwNUpgmC

🚀 Just built & deployed a Threat Intelligence Analyzer using Python + Streamlit The app analyzes SMS/email messages, extracts IOCs, and provides a basic threat score and verdict. Great hands-on experience with Python, modular design, and deploying real applications. More improvements coming soon 👨💻 Here is the link: https://lnkd.in/ezQGD7Pb #Python #CyberSecurity #ThreatIntelligence #Streamlit #GitHub #VersionControl #StudentDeveloper #PortfolioProject

🚨 High Risk Vulnerability Alert! 🚨 Picklescan, a popular Python library, is vulnerable to Remote Code Execution (RCE) via a flaw in its detection mechanism. Attackers can craft malicious pickle files that remain undetected and execute when loaded, potentially impacting any organization or individual relying on Picklescan for security. This highlights the importance of API security and keeping components up-to-date. Stay safe! #Picklescan #Python #RCE #OWASP #APIsecurity https://lnkd.in/ggUKugGz

So more than 10 years after Heartbleed, apparently, Python still managed to trust user input for the size of a buffer allocation… #SMH People need to learn capability-based security. Start thinking in terms of authority you give. I wonder how avoiding this could be abstracted away in a low-level library…

⚠️ High risk vulnerability detected in Picklescan, a Python library. Attackers can inject malicious code in pickle files that remains undetected but executes when the file is loaded. This highlights the importance of API security. CVE number pending. Potential impact includes supply chain attacks distributing infected pickle files across ML models, APIs, or saved Python objects. #Picklescan #Python #APIsecurity #OWASP #CWE94 🐍 https://lnkd.in/g5mufiNZ
