Malicious apps removed from Android Market
Mobile security firm Lookout reports that about two dozen apps were found to contain malware. Google has not yet commented.
Google has removed from the official Android Market about two dozen apps found to contain malware that can compromise data, mobile security firm Lookout is warning.
Between 30,000 and 120,000 Android devices may have been affected, Lookout said.
"This weekend, multiple applications available in the official Android Market were found to contain malware that can compromise a significant amount of personal data," the company said in a blog post late last night. "Likely created by the same developers who brought DroidDream to market back in March, more than 25 applications were found to be infected with a stripped down version of DroidDream we're calling 'Droid Dream Light' (DDLight)."
58 malicious apps from the market in March and remotely removed the apps from the devices they'd been downloaded to.
Google representatives did not immediately respond to e-mails seeking comment early today.
The problem was reported to Lookout by a developer who found that modified versions of his app and another developer's app were being distributed in the Android Market. Lookout confirmed that malicious code was inserted into the apps and identified markers that linked the code with DroidDream samples.
"We discovered 24 additional apps re-packaged and re-distributed with the malicious payload across a total of 4 different developer accounts," Lookout said.
Apps containing DDLight have been available for download from the official Android Market. Anyone who has downloaded the apps listed below may be affected. If you have downloaded these apps, contact firstname.lastname@example.org for help in removing them.
The list of infected applications includes:

Lookout users are already protected. According to Lookout, all Android users should:
Download apps only from trusted sources and reputable app markets. Examine the developer name, reviews, and star ratings.
Always check the permissions that an app requests. Make sure the permissions an app requests match the app's features.
Be alert for abnormal behavior on your phone that could signal an infection, such as unusual SMS or network activity.
Use a mobile security app that scans every app you download.
