Detecting and Identifying Malware: A New Signal Processing Goal

摘要

The Internet is now an essential part of many people's daily lives, both at home and at work. Today, it reaches all countries of the world, nearly a billion people, and supports trillions of dollars of transactions and millions of jobs. With this reach, it is not surprising that the Internet has been host to both positive and negative activities. Negative activities have grown from simple unde-sired use by unorganized hackers to extortion by organized crime. The term malware has come to mean a range of harmful software that ends up on users' computers, such as keystroke loggers, Web monitors, viruses, worms, and zombie software allowing unauthorized remote control.
