Abstract:

As users transition from desktop-based computers to mobile platforms, such as smart phones and tablets, the threats associated with ransomware increased. Security firms found Mobile users were less security-conscious than desktop users, choosing convenience over protection. This convenience made infections through ransomware easier as it transitions to a mobile environment. New tactics incorporated into the latest variants of ransomware, including Onion, requires less interaction with the user. The mobile transition established a new tactic for attackers to incorporate, attacking a business network from within instead of attempting to gain entry from outside the network. Ransomware posed a significant threat to businesses reliant on proprietary information and specific files by making them unavailable to the targeted business. The possible options to prevent a successful ransomware attack included to rely on antivirus software to catch it before encryption, maintain backup copies of important files, and to rely on security firms to discover decryption keys associated with the variant infecting the targeted files. Preventative measures should focus on user education and a proactive approach to security. An educated user acts as the first line of defense against malware. Education should include practical exercises for employees in the form of fire drills and interactive training. Proactive security for ransomware should focus on creating protocols designed to prevent unauthorized access and conducting activities without user input.
