Google to auto probe Android Market for malware

An answer to malware and rebuttal to calls for it to vet apps first.

Google has unveiled Bouncer, its answer to the growing threat of maliciously laced software available on the Android Market.

Bouncer will provide automated malware scanning of Android Market, but Google will not be bowing to calls for it to follow Apple in implementing an approval process for each application on its market.

Apple's mysterious vetting process is arguably one of the main reasons why there remains few if any cases of iOS malware available for download on the App Store.

However, Apple's process could also slow down the release of apps and provide obstacles to building the largest ecosystem. Security researcher Charlie Miller recently detailed some of those challenges during his efforts to bypass Apple's code signing process, which he did, landing him a one year ban from its developer program.

"Here’s how it works," Google's vice president of Android engineer, Hiroshi Lockheimer explained. "Once an application is uploaded, the service immediately starts analysing it for known malware, spyware and trojans."

It will also conduct a behavioral analysis of the app by running it in Google's cloud and comparing it against previously analysed apps to detect anything that might be considered untoward.

"We also analyse new developer accounts to help prevent malicious and repeat-offending developers from coming back," Lockheimer added.

While security vendors across the board reported a huge surge in Android malware throughout 2011, Google's own analysis showed a 40 per cent decline in "the number of potentially-malicious downloads from Android Market."

In other words, Google is saying there might be malware there, but people aren't necessarily downloading those apps.

"While it’s not possible to prevent bad people from building malware, the most important measurement is whether those bad applications are being installed from Android Market - and we know the rate is declining significantly," Lockheimer wrote, noting the drop occurred at the same time as security vendors were reporting a rise in Android malware.

Bouncer follows a controversial rant by Google open source champ, Chris DiBona, which slammed "the charlatans" peddling antivirus apps for Android.

Security Awareness Tip
Software security company www.clearswift.com gives some advice this holiday season to make sure employees don’t end up on Santa’s naughty list!


At a fundamental business level, social media is a useful additional tool for communicating and collaborating with customers, colleagues and new business prospects. From an HR point of view, the social web is not only useful for recruitment but also as a knowledge network. At an employee level, social media is changing the way we work: Employees increasingly expect to be able to access personal technology and services in the workplace. As the lines between work and home life blur, staff are looking for greater flexibility in their roles; working from home is an increasing trend, but so too is ‘home-ing from work’, where staff expect to be able to perform personal tasks at work.

But social media brings risk and reward to business in equal measure. Information security is a key concern: Many organisations view social media channels as yet another route along which sensitive data can escape from the business, whether accidentally or maliciously. On top of this, senior management may be concerned about the amount of time employees spend on social networks.

This cultural shift raises new questions about trust in the workplace, the balance of power in employer / employee relationship and levels of control over people and content.


Organisations using content and web security technology can manage the way their staff use email and the internet without having to resort to a default position of mistrust. With a whopping third of ANZ employers completely blocking social media access at work, there’s a real danger of throwing the benefits of collaboration out with the risks.


It doesn’t have to be that way.

Trust breeds responsibility: People underestimate the amount of company time they spend on personal browsing. Allow staff to view their own web usage and foster more responsible behaviour without undermining trust.


Know limits: Set clear limits on personal surfing and communicate them to users. Alert them when they are approaching their limit. Help your people to play by the rules.


Share the load: Spread responsibility for usage reporting among managers and department heads so everyone gets to see how their usage impacts on the rest of the organisation. This also gives managers greater control and visibility into usage.


Need to know: Yes, you need reports and visibility. What you don’t need is employee data becoming common knowledge. Access control means reporting can be adjusted on a need-to-know basis.

7 Ways to Protect Your Business Printers

Can a hacker burn down your business by remotely setting one of your printers on fire? Researchers at Columbia University have recently proposed such a scenario, although HP quickly denied that it's possible. However, even if your printers can't be used as remote firestarters, there are many risks involved in networking a printer.
