Recent attacks on Google exploited previously unknown hole in IE
According to an initial analysis by anti-virus vendor McAfee, the recent Chinese attacks on Google and other US companies probably exploited a previously unknown hole in Internet Explorer. Versions 6, 7 and 8 of the browser contain the hole which can be exploited to inject and execute code on Windows computers via specially crafted web pages. The attackers apparently used the flaw to inject a trojan downloader into compromised computers. The downloader then proceeded to retrieve further modules, including a back door that gave the attackers remote access to the computer, from a server via an SSL-encrypted connection. Links to the crafted web pages were likely sent in emails to selected employees of the targeted firms.
Having evaluated the data collected during malware analysis, McAfee believes that the authors used the code name "Aurora" for the attack that targeted Google, Adobe and dozens of other US companies probably including Yahoo, Symantec, Juniper Networks, Northrop Grumman and Dow Chemical. Aurora appears in the path names included in the malware binaries. The initial speculation was that specially crafted PDF files were used for the targeted attacks – in the past two years, PDFs have been a popular choice for attacks originating in China. The most recent campaign of a similar scale (Ghostnet) was discovered when foreign governments were attacked in March 2009. |
