Now E-Cigarette Can Give You Malware

E-cigarette MalwareE-cigarettes may be better for your health than normal ones, but spare a thought for your poor computer – electronic cigarettes have become the latest vector for malicious software, according to online reports.

Many e-cigarettes can be charged over USB, either with a special cable, or by plugging the cigarette itself directly into a USB port. That might be a USB port plugged into a wall socket or the port on a computer – but, if so, that means that a cheap e-cigarette from an untrustworthy supplier gains physical access to a device.

A report on social news site Reddit suggests that at least one “vaper” has suffered the downside of trusting their cigarette manufacturer. “One particular executive had a malware infection on his computer from which the source could not be determined,” the user writes. “After all traditional means of infection were covered, IT started looking into other possibilities.

“The made in China e-cigarette had malware hardcoded into the charger, and when plugged into a computer’s USB port the malware phoned home and infected the system.”

Any electrical device that uses a USB charger could be targeted in this way, and just about every one of these electrical devices will come from China.

In early November, figures obtained by the Press Association revealed that e-cigarettes and related equipment, such as chargers, were involved in more than 100 fires in less than two years.

CryptoPHP – Backdoor in Thousands of CMS Plugins and Themes Used to Hijack Web Servers

CryptoPHP BackdoorSecurity researchers have discovered thousands of backdoored plugins and themes for the popular content management systems (CMS) that could be used by attackers to compromise web servers on a large scale.

The Netherlands based security firm Fox IT has published a whitepaper revealing a new Backdoor named “CryptoPHP”. Security researchers have uncovered malicious plugins and themes for WordPress, Joomla and Drupal. However, there is a slight relief for Drupal users, as only themes are found to be infected from CryptoPHP backdoor.

In order to victimize site administrators, miscreants makes use of a simple social engineering trick. They often lured site admins to download pirated versions of commercial CMS plugins and themes for free. Once downloaded, the malicious theme or plugin included backdoor installed on the admins’ server.

By publishing pirated themes and plug-ins free for anyone to use instead of having to pay for them, the CryptoPHP actor is social-engineering site administrators into installing the included backdoor on their server“, Fox IT said in its analysis on the attack.

Once installed on a web server, the backdoor can be controlled by cyber criminals using various options such as command and control server (C&C) communication, email communication and manual control as well.

Other capabilities of the CryptoPHP backdoor include:

  • Integration into popular content management systems like WordPress, Drupal and Joomla
  • Public key encryption for communication between the compromised server and the command and control (C2) server
  • An extensive infrastructure in terms of C2 domains and IP’s
  • Backup mechanisms in place against C2 domain takedowns in the form of email communication
  • Manual control of the backdoor besides the C2 communication
  • Remote updating of the list of C2 servers
  • Ability to update itself

Miscreants are using CryptoPHP backdoor on compromised Web sites and Web servers for illegal Search Engine Optimization (SEO), which is also known as Black Hat SEO, researchers said in its report. It is because the compromised websites link to the websites of the attackers appear higher in search engine results.

Black Hat SEO is a group of techniques and tactics that focus on maximizing search engine results with non-human interaction with the pages, thus violating search engine guidelines. These include keyword stuffing, invisible text, doorway pages, adding unrelated keywords to the page content or page swapping.

The security company has discovered 16 variants of CryptoPHP Backdoor on thousands of of backdoored plugins and themes as of 12th November 2014. First version of the backdoor was appeared on the 25th of September 2013. The exact number of websites affected by the backdoor is undetermined, but the company estimates that at least a few thousand websites or possibly more are compromised.
