Cybercrime stories

Any use of network connected electronic devices such as computers or smartphones for criminal activity is classified as cybercrime. With a long history starting with the misuse of telephone systems (such as ‘phreaking’), cybercrime today includes the creation and distribution of viruses, ransomware, keyloggers and other malware, the download and use of malware produced by others, social engineering tactics such as phishing or (physical) impersonation, the theft and use of credentials for accessing computer systems or networks, and the theft of privileged data. Cybercrime is a broad and dynamic field, with cybercriminals constantly adapting their methods in pursuit of usually financial goals, but also occasionally seeking to disrupt, embarrass or shame their targets.
