New Video from @NoLimitSecu Discusses Judicial Digital Investigations

In this new video from No Limit Secu, the weekly French-language podcast dedicated to cybersecurity, Mathieu Odiber, a gendarmerie officer in the cyber command of the Ministry of the Interior, discusses judicial digital investigations. He is joined by several contributors, including Paul Amar, Nicolas Ruf, Étienne Ladent, Hervé Chaur, and Marc-Antoine Le dieu. Mathieu Odiber begins by explaining his role within the Ministry of the Interior's cyber command, which is a national competence responsible for combating cybercrime. He specifies that his work involves developing investigation strategies and training agencies within the Ministry of the Interior and other ministries in cybersecurity. He has also recently defended a doctoral thesis in private law and criminal sciences on digital evidence in criminal proceedings. Judicial digital investigations are a central topic of the discussion. Mathieu Odiber explains that, in a hyperconnected world, judicial investigations increasingly include digital components. Investigators often need to copy hard drives, retrieve VHDs (Virtual Hard Disks) or disk copies from USXs (Unified Storage Systems). He emphasizes the importance of adhering to the code of criminal procedure to ensure that the actions of investigators are legal and proportionate. The discussion also addresses the distinction between digital investigation and digital forensics. The former involves searching for distant traces and clues, while the latter involves examining digital media such as hard drives, phones, or connected cars. Mathieu Odiber explains that investigators often face technical challenges, such as recovering deleted data or breaking unlock codes. A crucial point of the discussion is the importance of proportionality and gradation in digital investigations. Investigators must ensure that the means used are proportional to the severity of the offense. For example, intrusive methods such as infiltration are only used for cases of organized crime. Mathieu Odiber also talks about the National Digital Expertise Center (CNE), a division of the Ministry of the Interior's cyber command specializing in complex investigations and data processing. This center includes more than fifty military and civilian personnel who are experts in digital trace. They are capable of disassembling computer components, repairing damaged digital media, and finding software sub-layers with encrypted partitions. The video also discusses how cybersecurity experts can assist judicial investigations. Mathieu Odiber recommends reporting any suspicious findings to the competent authorities, such as the CERT of ANSSI or the Pharos platform of the Ministry of the Interior. He warns against trying to substitute for investigators, emphasizing the importance of letting professionals handle investigations. Finally, Mathieu Odiber discusses the future evolution of judicial digital investigations. He mentions the challenges posed by artificial intelligence, which can be used by both investigators and cybercriminals. He also highlights the importance of digital education to protect younger generations from cyber threats. In conclusion, Mathieu Odiber thanks the listeners and encourages them to stay informed about cybersecurity. He mentions several available resources, such as the Ministry of the Interior's website and the Ma Sécurité.fr app, which offer advice and information on preventing cyber threats.
