Two interns at Matasano Security exposed security flaws in some of the most widely used remote administration tools, which can supposedly be used to defend against the attackers. Can you explain the RAT security flaws that were discovered and how they can be used for defense purposes?

Remote administration tools (RATs), the common name for the broad category of software tools hackers develop and use for malicious purposes, are a potential weak link in enterprise security, regardless of whether any particular tool was designed for legitimate use or for use in an attack. The fact that some of the most widely used malicious RATs had security flaws is not a surprise, given the immaturity of the software development practices used by most attackers. Some RATs, like BackOrifice and Dameware, were created using more secure software development practices, and the quality of the tools typically reflect that, but for the most part, RATs are not developed using these more sophisticated practices.
The RAT security vulnerabilities discovered by the Matasano interns included SQL
injection, unauthorized reading of arbitrary files, vulnerabilities in included third-party
files and man-in-the-middle
attacks. These attacks could allow an attacker to gain access to the system by exploiting a
vulnerability in the RAT, allowing access to a potential new attacker.
Exploiting these vulnerabilities for defensive purposes on internal hosts owned by your enterprise
and where your enterprise is responsible for the system is one potential option to remediate the
system and defeat an attacker. However, to be clear, many would consider such a tactic to be
"hacking back," and such aggressive methods of offensive security are at best highly controversial,
and at worst illegal if performed against a system your enterprise doesn't own. A much better
option is to use established support tools to remediate a system where one of the vulnerable RATs
was installed without authorization. In such cases, the system would most likely be compromised, so
you might still need to reimage the system after backing up its data.
