‎pcAnywhere Exploit- More Than 200,000 Windows PCs Can Be Hijacked

pcAnywhere Exploit More Than 200,000 Windows PCs Can Be Hijacked 
According to a researcher hackers have made pcAnywhere hackers exploiting bugs in the Symantec software which can hijack as many as 200,000 systems connected to the Internet. Also Rapid7 developer of Metasploit confirmed that an estimated 150,000-to-200,000 PCs are running an as-yet-unpatched copy of the Symantec software, and are thus vulnerable to be hijacked by remote attacks, which could commandeer the machine's keyboard and mouse, and view what's on the screen.This bug has been found just after Symantec took the unprecedented step of telling pcAnywhere users to disable or uninstall the program because attackers had obtained the remote access software's source code. According to an exclusive report of Computer World- 
Credit Card Data at Risk:-
About 2.5% of those vulnerable Windows PCs, or between 3,450 and 5,000 systems, are running a point-of-sale system - Windows PCs are often paired with cash registers by small businesses - potentially putting credit card data at risk, said HD Moore, chief security officer at Rapid7.
Moore reached those conclusions by scanning the internet for the TCP port the software leaves open for incoming commands, running more targeted scans for evidence of the remote access software, then using the number of programs that identify themselves as older than the patched editions to estimate the extent of the problem.
Some of the computers returned queries with replies consistent with specific point-of-sale software, Moore said. Point-of-sale software often relies on pcAnywhere for remote support, not for transmitting credit card data, but by exploiting pcAnywhere, a cybercriminal could control the machine and easily harvest the information. "These point-of-sale systems are an attractive target for break-in," said Moore.
Exploitable Bugs:-
DoS attacks can sometimes be leveraged to execute remote code. The source code leak also ups the risk to pcAnywhere users, Moore maintained, even though Symantec has patched some flaws. With the source code at their disposal and the software's problems highlighted in the media, researchers on both sides of the law will spend time looking for vulnerabilities, he said. And some of that research may result in new, exploitable bugs.
An anonymous researcher has already published findings from his examination of the pcAnywhere source code. Although his description on the InfoSec Institute website did not claim any new vulnerabilities, he noted that the source code also revealed the workings of LiveUpdate, the Symantec service used to update much of its software, including its consumer antivirus programs, such as Norton Antivirus. "We now know how their LiveUpdate system works thanks to the included architecture plans and full source code," said the researcher. Symantec did not immediately reply to a request for comment on Moore's research or Norman's DoS proof-of-concept.
