EdTalk Video: Ransomware cyberattacks are on the rise
(EdTalk videos launching Monday 19 April 2021)
Computer viruses have been developed since 1972, and their evolution has undergone enormous changes since then. Virus developers use a variety of techniques to avoid anti-virus software, including polymorphic, metamorphic, and malicious code mutations. The metamorphic virus, for example, is rewritten with each iteration, so that each subsequent version of the code differs from the previous one. Today, virus developers focus on a specific class of virus that infiltrates computer and mobile devices to encrypt victims’ data and demand payment in exchange for a cryptographic key to decrypt the data. Ransomware will remain the number one public and industrial enemy, with attacks becoming more sophisticated and threat actors becoming more successful with each passing year. This EDtalk is for IT and non-IT specialists who want to learn more about the ransomware threat and landscape.
