Report : PHP SuperGlobals are Vulnerable to Hackers

PHP SuperGlobals VulnerabilityIn the most recent Hacker Intelligence Initiative Report – “PHP SuperGlobals: Supersized Trouble“, Imperva analyses vulnerabilities found in the SuperGlobal parameters of the PHP platform, and finds that a multi-step attack requires a multi-layered application security solution.

In addition to local and global scope variables, PHP has several predefined variables that are called SuperGlobals. These variables are available to the PHP script in both scopes, with no need for explicit declaration. 4 SuperGlobals were introduced to PHP in version 4.1.0.

The PHP SuperGlobal parameters are gaining popularity within the hacking community because they incorporate multiple security problems into an advanced web threat that can break application logic, compromise servers, and result in fraudulent transactions and data theft.

In one month, Imperva’s research team noted an average of 144 attacks per application that contained attack vectors related to SuperGlobal parameters. Furthermore, researchers witnessed attack campaigns lasting more than five months with request burst floods of up to 90 hits per minute on a single application.

The effects of these attacks can be great as the PHP platform is by far the most popular web application development platform, powering more than 80 percent of all websites, including Facebook and Wikipedia. Clearly, it is time for the security community to devote more attention to this issue.

The report also finds that hackers are increasingly capable of packaging higher levels of sophistication into simpler scripts, and identifies PHP SuperGlobals as a prime target that yields a high return on investment.

First Ever iPhone Malware Scanner

VirusBarrierA French security company known for its Mac OS X antivirus software today released the first malware-scanning app for the iPhone and iPad and iPod Touch.

Intego’s VirusBarrier for iOS has been approved by Apple, and debuted on the App Store Tuesday for $2.99.

Because iOS prevents the program from accessing the file system or conducting automatic or scheduled scans — as do virtually all Mac and Windows antivirus software — VirusBarrier must be manually engaged, and then scans only file attachments and files on remote servers, said Peter James, a spokesman for Intego.

VirusBarrier for iOS can scan email attachments in a variety of formats, including Microsoft’s Word, Excel and PowerPoint; PDF documents; JavaScript files; and Windows executables, those files tagged with the .exe extension. It can also scan files in a Dropbox folder, those stored on MobileMe’s iDisk, or files downloaded via the iOS version of Safari.

The scanning engine and signatures — the digital “fingerprints” used to detect malware — in VirusBarrier for iOS are identical to those used by Intego’s Mac OS X product line.

VirusBarrier for iOS lets iPhone and iPad users run on-demand scans of email attachments before those files are opened or forwarded.

When an email attachment is received by the iPhone, iPad or iPod Touch, the user can intercede by calling on VirusBarrier, which then scans the file for possible infection before the file is opened or forwarded to others.

VirusBarrier for iOS can be downloaded to an iPhone, iPad or iPod Touch from Apple’s App Store. It requires iOS 4.0 or later.
