A Primer for Secure Coding in PHP and MySQL


PHP is an incredibly popular language for creating dynamic web applications — websites such as Facebook are built on it. This can be attributed to many reasons; it is easy to learn, easy to install and does not require the user to compile code. An unfortunate side effect of the ease of development with PHP is a tendency to ignore security during the development process.

In this post I will discuss some of the ways to make your PHP apps more secure. I will go through creating a PHP web app that connects to a MySQL back end database. The application will be a simple address book. The approach I will take is one of layered security.  There is no sure fire quick method of blocking all attacks, but using the layered security approach we severely limit our exposure.

Webroot Bulletin Regarding AV-Comparatives Results


By Grayson Milbourne and Joe Jaroch

If there is one thing that can be observed about the AV industry, it is that no solution is ever 100% effective at blocking malware. With this in mind, Webroot SecureAnywhere (WSA) was designed to protect users even in cases where undetected malicious software has made it onto the system.

AV-Comparatives recently published results for June’s “Real World” Protection Test. This test aims to replicate a real world experience for how malware would infect a PC. The scores indicate how many threats were detected vs. missed.

Trojan Downloaders actively utilizing Dropbox for malware distribution


By Curtis Fechner

It’s never surprising to see the multitude of tactics a cybercriminal will use to deliver malware. In this case, I came across a collection of files masquerading as RealNetworks updater executables. These files were all located in a user’s %AppData%\real\update_ob\ directory, and the sizes were all quite consistent.

At first glance there was nothing too special about this finding – malware appearing to be legitimate software is nothing new.

When I looked into the specific behaviors of the file, it became clearer that the software is in fact malicious, and that it is actually downloading malicious files from the popular web-based file hosting service Dropbox. These files came in two varieties: some files were randomly-named; other files were named for legitimate software. For example: utorrent.exe, Picasa3.exe, Skype.exe, and Qttask.exe.

An Evolution of Android Malware “My How You’ve Grown PJAPPS!” (Part 1)


By Nathan Collier

We’ve all seen software grow.  We watch as our favorite software adds on new features and becomes better at what it does.  Malware writers are no different, they want their software to have more features as well as steal even more information. PJApps is a good example of this. PJApps is a Trojan that’s been around for a while causing havoc by being bundled in legitimate applications found in alternative Android markets, it is capable of opening a backdoor, stealing data and blocking sms behind the scenes.  In one variant of PJApps it requests the following permissions to steal information:

INTERNET
RECEIVE_SMS
SEND_SMS
READ_HISTORY_BOOKMARKS
WRITE_HISTORY_BOOKMARKS
INSTALL_PACKAGES
WRITE_EXTERNAL_STORAGE
READ_PHONE_STATE

Here’s some of things the older variants of PJApps stole:

-SIM Card Number
-Telephone Number
-IMSI Number

Top 7 Cybersecurity Predictions for 2012


By Mel Morris

From Stuxnet to Sony, a number of cyberattacks emerged in 2011 that experts have predicted for quite some time. I predict 2012 will be even more pivotal, thrusting cybersecurity into the spotlight. These are my top seven forecasts for the year ahead:

1) Targeted, zero-day attacks will be the norm.
Looking back over the past year, an increasing number of breaches were the result of custom malware and exploits targeting specific enterprises. I predict 2012 will be the year of targeted attacks, which have slowly evolved from large-scale threats to unique attacks designed to infect a handful of very specific people.  Traditional blacklist and signature approaches have already become ineffective; once a virus is spotted, malware writers simply create a new one. As targeted, zero-day attacks intensify, more security vendors will realize the pressing need to analyze threats and behavior more holistically.

2) 2012 will be the start of a revolution.
For the last several years, the security industry and cybercriminals have had a symbiotic relationship that has kept the market in balance. The “good guys” have done just enough to thwart attacks – and the bad guys haven’t needed to dramatically evolve as they’re still making money doing exactly what they’re doing. I predict the scales will tip in the coming year. More innovative and effective security technology will drive a revolution and we’ll see a heated battle emerge between security companies and cybercriminals. It’s survival of the fittest.  As soon as cloud-based technology and behavioral protection strengthen their foothold in the antimalware sector, hackers and cyber mafias will up the ante and scope out new vulnerabilities.

3) Cyber threats will gain political traction.
The Stuxnet worm is an example of something we detected long ago, and its impact has now taken on a whole new meaning. The virus’s sophisticated ability to infiltrate government systems, silently gather information, and disable nuclear power plants has prompted a wakeup call, driving leaders to reassess federal technology standards and regulations. Stuxnet gives us a very real and very scary glimpse of what’s to come.

4)  Masses will migrate to cloud platforms.
Now that Cloud has an “i” front of it, the cloud will truly hit the mainstream. The appeal of file sharing and remote access will be a major draw for an increasingly tech savvy population that connects to the Internet from tablets, smartphones, and multiple PCs. This will not only drive widespread adoption of cloud-based tools and applications amongst consumers, but it will dramatically accelerate migration in the business world. Many companies are already on board with cloud platforms and applications, but the power of the masses will act as a tipping point, pushing the vast majority of IT professionals to shun old-school, on-premise approaches and look to the cloud for infrastructure and data solutions.

5) Your smartphone will be a target. Security companies have done a fairly good job of stopping attacks at the endpoint, and this will lead cybercriminals to focus their efforts more heavily on mobile devices, which are still quite vulnerable in today’s environment. We will see an increase in Android and iPhone attacks: rogue apps, malicious links, and spyware targeted at smartphones and tablets. It’s all about data, and business users and consumers alike store an abundance of highly sensitive and poorly guarded information on their mobile devices.

6) Legitimate applications will be used for illegitimate activities.
Rogue Android apps are just the tip of the iceberg. We load our mobile devices with applications that are designed to simplify our lives, yet we don’t stop to consider what else they are capable of – or what someone is capable of manipulating them to do. Even legitimate apps can grab information and use it without our permission. A simple glance at an application like Plane Finder illustrates the vast amount of data that is at anyone’s fingertips. And that’s not to mention the many other opportunities roaming devices present; a criminal could leverage a mobile device to pick up data from a nearby network, or hack into a plane’s WiFi connection and send signals to devices left in improper flight mode.

7) Our weakest link will be strengthened.
When it comes to security, the weakest link has always been people. In 2012, indifference toward security will diminish. Businesses will invest in security and strengthen duty of care measures. Employees and consumers will see the ramifications of breaches and begin incorporating smart Internet practices into their everyday behaviors.

A look inside the SpyEye Trojan admin console


By Michael Johnson

At Webroot we’ve been researching and chronicling developments with SpyEye since we first saw it in April 2010. This nasty Trojan is the successor to the Zeus Trojan, and it became essentially the main rootkit available for sale after the author of ZeuS left the underground market and sold ZeuS sources to the SpyEye team.

Over the last six months, through Webroot’s real-time watch technology and through my own adventures hunting malware proactively in my spare time, I’ve noticed an extreme escalation of SpyEye infections.

Last week I came across a URL for a password-protected site and at first didn’t think very much of it. But once I logged in, I realized I was on the administrator’s page of a SpyEye Panel, with what appeared to be full access. The administration panel was so easy to run, a fifth grader could do it.

At first glance, there were about 3,000 bots with approximately 600 active at the moment I was looking. The site was moved four days later which at that point, the number of bots was quickly approaching 10,000.

Now some of this is started to make sense. The authors of SpyEye have made it so simple to operate and  in case of any trouble, apparently provide support promptly. Their selling points are working quite effectively and a lot of the wrong type of people are able to acquire the builders, Command and Control Servers for a small amount of money.

Taking a look at some of the screenshots, it doesn’t look very nice from any view.

Morto Worm Annoyances Outstrip Functionality

The past couple of days have been very busy for a lot of people, following the announcement by Microsoft that they had discovered a new network worm called Morto. After reading the refreshingly thorough writeup about Morto from both Microsoft and our partner Sophos, we were surprised to find that a few of our customers had been infected — and cleaned up — beginning with some poor schlub in South Africa as early as July 23rd, but the worm kicked into high gear last Thursday and began to propagate rapidly.

But, as much as the technical details in these posts are useful for researchers and analysts, they don’t really get to the heart of how a user of an infected computer would be affected by the worm. So, after spending a bit of time infecting some of my own machines these past couple days, I wanted to share my hands-on experience with you.

Bottom line, the worm was written to spread to (and infect) the computers run by people who don’t take security seriously: It copies itself to other computers by trying to Remote Desktop into those computers using a list of what can only be described as completely moronic passwords (the full list is on Microsoft’s technical writeup about the worm). The repurcussions are that people (or companies) who use poor quality, easily guessed passwords have been (or are going to get) spanked by Morto, and then they’ll be really irritated at the (reversible but obnoxious) changes the worm makes to the behavior of the infected computer.

Black Hat Redux: Botnet Takedown Mistakes to Avoid

FireEye's Lanstein and Wolf speak at Black Hat

I’ve worked in the security industry for nearly five years, and it was apparent early on that the most successful people in this field bring to their work a passion and a commitment to protecting not only one’s customers, but to providing a certain level of information about security threats to the world at-large, so even your non-customers can help or protect themselves.

It can be hard to know where to stop once you get on a roll. Malware infections frequently lead to unexplored, interesting backwaters on the Internet. And, sometimes, those backwaters are where the criminals run those operations. When I stumble upon a criminal network or a botnet controller, it simply doesn’t feel like I’ve done enough when I merely add signatures which block or remediate infections and communications with a command-and-control server from Webroot customers. If malicious behavior depends on one or more Internet sites that send instructions, my (and many others’) initial reaction is we need to shut that down, permanently. But sometimes, a too-rapid reaction can blow back in your face.

Obviously, that was also the case when Alex Lanstein and Julia Wolf of internet security firm FireEye stumbled upon the Rustock botnet. At one time, before law enforcement in several countries swooped in on the data centers hosting the botnet’s command-and-control (CnC) infrastructure in a coordinated raid earlier this year, the massive network of Rustock-infected computers was responsible for about half of spam flooding the ‘net. The researchers’ instincts to engineer a takedown of the botnet sounded very familiar, but their initial attempts to do so backfired, and may have even spurred the malware developers to change their game, and may have made it more difficult, eventually, to eliminate the CnC altogether.

Targeted Malware Infects Windows-based Cash Registers


By Andrew Brandt

Add to FacebookAdd to DiggAdd to Del.icio.usAdd to StumbleuponAdd to RedditAdd to BlinklistAdd to TwitterAdd to TechnoratiAdd to Yahoo BuzzAdd to Newsvine

A serious, targeted threat from customized malware that steals credit card magnetic strip track data could literally bankrupt your business. That’s the message two security researchers from Trustwave gave at their talk during the Defcon computer security conference Saturday.

The researchers, Jibran Ilyas and Nicholas Percoco of Trustwave Spider Labs, respond to calls for help when businesses find malware in critical systems. When banks field reports of credit card fraud, they try to find the earliest common location or business where all the victims used their card. When they do, the bank calls the business, who then call in the researchers.

In their talk, Malware Freak Show 3, the researchers reported on several types of malware all of which are designed to steal the so-called Track 1 data — the information encoded on the magnetic strip on the back of the card — when a salesperson or waiter swipes the credit card attached to the cash register.

The malware may reside on the register (a device that, in many cases, is simply a custom-configured Windows computer) or on a server in the back room of the business that’s used to process credit card transactions. Once the malware has the Track 1 data, it transmits the string of numbers to remote locations, where the data can be used to produce fake, but functional, physical credit cards. The thieves can then sell or use the cards to purchase valuable merchandise.
