Good Code, Bad Computations: A Computer Security Gray Area

Two graduate students from UC San Diego’s computer science department—Erik Buchanan and Ryan Roemer—have just published work showing that the process of building bad programs from good code using “return-oriented programming” can be automated and that this vulnerability applies to RISC computer architectures and not just the x86 architecture (which includes the vast majority of personal...

Study finds major computer virus threat

Two graduate students from UC-San Diego, Erik Buchanan and Ryan Roemer, have published a paper demonstrating that the process of creating an existing, known form of computer virus can be automated much more easily than was previously thought. Application of a concept known as "return-oriented programming" allow even properly written programs to be taken over completely, thereby becoming...

New Malware Technique Bypasses Traditional Defenses

A new way to subvert computers threatens to make traditional malware defenses obsolete. Two University of California, San Diego computer science graduate students -- Erik Buchanan and Ryan Roemer -- have demonstrated a way to turn good computer code into malicious instructions using a technique called "return-oriented programming."
