Application Security Is National Security

Hacks targeting U.S. government computers are coming from China. We knew that. The Chinese hackers are relying on zero-day software vulnerabilities to exploit critical systems. So, tell me again: why aren't we doing more to require applications be built secure from the start?

Hacks targeting U.S. government computers are coming from China. We knew that. The Chinese hackers are relying on zero-day software vulnerabilities to exploit critical systems. So, tell me again: why aren't we doing more to require applications be built secure from the start?This is an excerpt from the report, Capability of the People's Republic of China to Conduct Cyber Warfare and Computer Network Exploitation [.pdf]:

China is likely using its maturing computer network exploitation capability to support intelligence collection against the US Government and industry by conducting a long term, sophisticated, computer network exploitation campaign. The problem is characterized by disciplined, standardized operations, sophisticated techniques, access to high-end software development resources, a deep knowledge of the targeted networks, and an ability to sustain activities inside targeted networks, sometimes over a period of months.

Analysis of these intrusions is yielding increasing evidence that the intruders are turning to Chinese "black hat" programmers (i.e. individuals who support illegal hacking activities) for customized tools that exploit vulnerabilities in software that vendors have not yet discovered. This type of attack is known as a "zero day exploit" (or "0-day") as the defenders haven't yet started counting the days since the release of vulnerability information. Although these relationships do not prove any government affiliation, it suggests that the individuals participating in ongoing penetrations of US networks have Chinese language skills and have well established ties with the Chinese underground hacker community. Alternately, it may imply that he individuals targeting US networks have access to a well resourced infrastructure that is able to broker these relationships with the Chinese blackhat hacker community and provide tool development support often while an operation is underway.

More clearly: our adversaries (not just criminally motivated Black Hats, but state-sponsored adversaries) are using the fact that most software shipped today is both shoddily designed and insecure to steal billions of intellectual property and state security secrets every year.

The report provided a case study of on infiltration on an unnamed U.S. business. The attack was made possible by a flaw in Adobe Acrobat. And the attack was initiated in the typical way: an e-mail with a maliciously crafted attachment that, once clicked, executes the attack on some software vulnerability and a Trojan horse, botnet, or keystroke logger is injected into the user's system.

These attacks happen in a split second, and anyone can fall victim -- especially when these e-mails come from someone who knows the plenty about the person or organization being targeted. And they're made possible because the PDF viewers, word processors, spreadsheets, Internet browsers, Web applications -- are all -- to some degree vulnerable to attack.

Unfortunately, it's you -- the end user or the organization -- who always suffers the consequences of the vulnerability: not the software developer. Sure, they'll have to endure the cost of developing a patch for a discovered vulnerability: but they're not held liable for your having lost $20 million is research and development on that fancy new widget. Nor are they held liable when a foreign government accesses military secrets.

Perhaps it's time part of the risk for developing insecure software shifts onto software developers. End users have businesses have been shouldering the risk, and the cost, for far too long.

What's This?
In a digital world inundated with advanced security threats, Intel Security seeks to transform how we live and work to keep our information secure. Through hardware and software development, Intel Security delivers robust solutions that integrate security into every layer of every digital device. In combining the security expertise of McAfee with the innovation, performance, and trust of Intel, this vision becomes a reality.

As we rely on technology to enhance our everyday and business life, we must too consider the security of the intellectual property and confidential data that is housed on these devices. As we increase the number of devices we use, we increase the number of gateways and opportunity for security threats. Intel Security takes the “security connected” approach to ensure that every device is secure, and that all security solutions are seamlessly integrated.

Enterprise Vulnerabilities
From DHS/US-CERT's National Vulnerability Database
CVE-2014-7298
Published: 2014-10-24
adsetgroups in Centrify Server Suite 2008 through 2014.1 and Centrify DirectControl 3.x through 4.2.0 on Linux and UNIX allows local users to read arbitrary files with root privileges by leveraging improperly protected setuid functionality.

CVE-2014-8346
Published: 2014-10-24
The Remote Controls feature on Samsung mobile devices does not validate the source of lock-code data received over a network, which makes it easier for remote attackers to cause a denial of service (screen locking with an arbitrary code) by triggering unexpected Find My Mobile network traffic.

CVE-2014-0619
Published: 2014-10-23
Untrusted search path vulnerability in Hamster Free ZIP Archiver 2.0.1.7 allows local users to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse dwmapi.dll that is located in the current working directory.

CVE-2014-2230
Published: 2014-10-23
Open redirect vulnerability in the header function in adclick.php in OpenX 2.8.10 and earlier allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the (1) dest parameter to adclick.php or (2) _maxdest parameter to ck.php.

CVE-2014-7281
Published: 2014-10-23
Cross-site request forgery (CSRF) vulnerability in Shenzhen Tenda Technology Tenda A32 Router with firmware 5.07.53_CN allows remote attackers to hijack the authentication of administrators for requests that reboot the device via a request to goform/SysToolReboot.
