As a result, videoconferencing market is expected to grow from US $6.28 billion in 2021 to US $12.99 billion by 2028 according to a Fortune Business Insight report.
In fact, during the pandemic, the work landscape changed dramatically as more companies shifted to a work-from-home model.
Although network communications are encrypted, we successfully retrieve useful artifacts such as IPs of server domains and host devices along with message/event timestamps.ĬOVID-19 has been a prime catalyst in the widespread adoption of videoconferencing applications such as Zoom, Cisco WebEx, Microsoft Teams, Adobe Connect, and BlueJeans for professional and personal use. Additionally, we identify anti-forensic artifacts such as deleted chat messages. We develop a memory parsing tool for Cisco WebEx based on the extracted artifacts. These include user credentials, emails, user IDs, profile photos, chat messages, shared media, meeting information including meeting passwords, contacts, Advanced Encryption Standard (AES) keys, keyword searches, timestamps, and call logs. From the extracted artifacts, it is evident that valuable user data can be retrieved from different data localities. We focus on three digital forensic areas, namely memory, disk space, and network forensics. More precisely, we present the results of the forensic investigation of Cisco WebEx desktop client, web, and Android smartphone applications. In this contribution, we present a detailed forensic analysis of Cisco WebEx which is among the top three videoconferencing applications available today. Digital forensic analysis of videoconferencing applications has received considerable attention recently, owing to the wider adoption and diffusion of such applications following the recent COVID-19 pandemic.
