![]() ![]() Compared with other techniques, fuzzing requires few knowledge of targets and could be easily scaled up to large applications, and thus has become the most popular vulnerability discovery solution, especially in the industry. Techniques including static analysis, dynamic analysis, symbolic execution and fuzzing ( Liu et al. It has caused serious crisis management problems and huge losses to many industries, such as finance, energy and medical treatment.Ĭonsidering the serious damages caused by vulnerabilities, much effort has been devoted to vulnerability discovery techniques towards software and information systems. The WannaCry ransomware attack ( Wikipedia and Wannacry ransomware attack 2017) outbroke in May 2017, which exploits a vulnerability in Server Message Block (SMB) protocol, is reported to have infected more than 230,000 computers in over 150 countries within one day. Attack on vulnerabilities, especially on zero day vulnerabilities, can result in serious damages. Defined in RFC 2828 ( Shirey 2000), a vulnerability is a flaw or weakness in a system’s design, implementation, or operation and management that could be exploited to violate the system’s security policy. ![]() Very nice to see.Vulnerabilities have become the root cause of threats towards cyberspace security. "We've always done fuzzing (who remembers the old "crashme" program that just generated random code and jumped to it? We used to do that quite actively very early on), but people have been doing some nice targeted fuzzing of driver subsystems etc, and there's been various fixes (not just this last week either) coming out of those efforts. "The other thing perhaps worth mentioning is how much random fuzzing people are doing, and it's finding things," writes Torvalds. Microsoft has launched the Project Springfield fuzzing service to allow enterprise customers to test their own software.Īs Torvalds points out, Linux kernel developers have been using fuzzing programs since the beginning, such as tools like "crashme", which was released in 1991 and nearly 20 years later was used by Google security researcher Tavis Ormandy to test how well shielded a host is when untrusted data is being processed in a virtual machine. Google uses a variety of fuzzing tools to find bugs in its and other vendors' software. ![]()
