Sergei Shevchenko senior malware analyst at security firm, PC Tools told that the exploit discovered by Dowd changes the scope of threats from Flash: "Previous Flash exploits were mostly designed to cause browser crashes, hang-ups, or for the worst-case scenario, an ability to parse the contents of user files. "Basically you could exploit it successfully and the application could continue to function as if nothing happened and you wouldn't know you have just been hacked." "I was able to make a malicious SWF file that could exploit both Firefox and Internet Explorer with the same file without crashing either browser," he said. The flaw, which was patched in Adobe's latest Flash security update, relates to a memory corruption vulnerability that occurs when Flash interprets a malicious Shockwave Flash (SWF) file - commonly used in online advertising and video streaming - and takes advantage of functionality provided by the ActionScript Virtual Machine, an integral part of Adobe Flash Player, according to Dowd's research.ĭowd was also able to craft the exploit so that an attack does not leave the usual tell-tale signs. By using more targeted application-specific attacks, these vulnerabilities are, in fact, exploitable in a number of cases quite reliably," said Dowd. "The reason we put out the research is to draw attention to how serious these types of vulnerabilities can be. The result is that security researchers have discounted this method of exploitation, said Dowd. "A significant amount of time you can exploit a bug, but a lot of memory corruption bugs are not nearly as reliable as they used to be because of operating system hardening," Dowd told.

Operating system "run time" defences have reduced the reliability of many similar exploits, according to Dowd, so even where one is discovered, the chances of it working have been slim.

Security researchers are interested in Dowd's discovery because Flash exploits have not typically been reliable or potent, which has resulted in researchers underestimating the potential impact of Flash exploits. Google Drive alternative: Decentralized and encrypted
