In today’s era, where mobile devices have become an integral part of our daily lives, ensuring the security of mobile applications has become increasingly crucial. Mobile penetration testing, a specialized subfield within the realm of cybersecurity, plays a vital role in safeguarding mobile ecosystems against the ever-evolving landscape of threats. The ubiquity of mobile devices has made them a prime target for cybercriminals, and the data and functionality accessed through mobile applications make them valuable assets to protect. Mobile penetration testing is designed to identify vulnerabilities, weaknesses, and potential exploits within mobile applications and the devices themselves. Unlike traditional penetration testing, which often focuses on network and server security, mobile penetration testing zeroes in on the unique challenges posed by mobile platforms. Mobile penetration testing, a specialized field within cybersecurity, is an essential tool in the Cybersecurity specialists’ toolkit to protect mobile ecosystems from emerging threats. This article introduces mobile penetration testing, emphasizing its significance, including comprehensive learning labs for Android and iOS platforms, and highlighting how it distinctly differs from traditional penetration testing methodologies.

Al-Mg laminated macro composites （LMC） have garnered attention due to their excellent mechanical properties and low density. However， their weak corrosion resistance has limited their industrial applications. Plasma electrolytic oxidation （PEO） has been explored as a potential solution to this issue by producing hard and thick oxide coatings on the surface of Al-Mg LMCs manufactured through hot extrusion bonding. In this study， PEO coatings were prepared on Al-Mg LMCs using both unipolar and bipolar waveforms in an appropriate electrolyte for both aluminum and magnesium alloys. The techniques of FESEM/EDX， GIXRD， and electrochemical methods of Potentiodynamic polarization and EIS were carried out. The results revealed that the coatings produced using the bipolar waveform exhibited lower porosity and higher thickness than those produced using the unipolar one. The corrosion performance of the specimens' cut edge was investigated using electrochemical impedance spectroscopy （EIS） after 1， 8， and 12 hours of immersion in a 3.5%wt. NaCl solution. It was observed that the coating produced using the bipolar waveform demonstrated the highest corrosion resistance after 12 hours of immersion， with an estimated corrosion resistance of 41.87 kΩ.cm2， which was approximately three times higher than that of the unipolar coating. Notably， no signs of galvanic corrosion were observed in the LMC， and only minor corrosion attacks were observed on the magnesium layer in some areas.
