The computer-security firm Symantec says it may have found some of the most sophisticated malicious software ever made. The cyber-espionage bug, called Regin, has been making attacks for many years without being caught.
Most malware – which you are tricked into loading when you access free software, illegal film downloads or pornography sites – wants to spread as widely as possible. It aims to gather data that can be used for malicious purposes, such as holding your device ransom. That is why it spreads indiscriminately. The six-year-old Regin malware is different. It is unlikely to accidentally infect your system, unless the attacker wants that to happen.
