Få har väl undgått att läsa om malware-bomben som slog ner förra veckan, då det uppdagades att en utvecklare vid namn ”myournet” hade släppt ett stort antal infekterade applikationer på Android Market, vilka sedan av intet ont anande användare laddades ner och installerades på upp till 200 000 telefoner världen över.
Google tog omedelbart bort alla skadliga applikationer då detta uppdagades, men då var det förstås redan för sent för de som hade hunnit installera någon av de infekterade apparna. För att komma till rätta med problemet så släppte Google under gårdagen en egen app vilken är specifikt utvecklad för att rensa upp infekterade telefoner.
Google skriver själva:
On Tuesday evening, the Android team was made aware of a number of malicious applications published to Android Market. Within minutes of becoming aware, we identified and removed the malicious applications. The applications took advantage of known vulnerabilities which don’t affect Android versions 2.2.2 or higher. For affected devices, we believe that the only information the attacker(s) were able to gather was device-specific (IMEI/IMSI, unique codes which are used to identify mobile devices, and the version of Android running on your device). But given the nature of the exploits, the attacker(s) could access other data, which is why we’ve taken a number of steps to protect those who downloaded a malicious application:
1. We removed the malicious applications from Android Market, suspended the associated developer accounts, and contacted law enforcement about the attack.
2. We are remotely removing the malicious applications from affected devices. This remote application removal feature is one of many security controls the Android team can use to help protect users from malicious applications.
3. We are pushing an Android Market security update to all affected devices that undoes the exploits to prevent the attacker(s) from accessing any more information from affected devices. If your device has been affected, you will receive an email from firstname.lastname@example.org over the next 72 hours. You will also receive a notification on your device that “Android Market Security Tool March 2011” has been installed. You may also receive notification(s) on your device that an application has been removed. You are not required to take any action from there; the update will automatically undo the exploit. Within 24 hours of the exploit being undone, you will receive a second email.
4. We are adding a number of measures to help prevent additional malicious applications using similar exploits from being distributed through Android Market and are working with our partners to provide the fix for the underlying security issues.
For more details, please visit the Android Market Help Center. We always encourage you to check the list of permissions when installing an application from Android Market. Security is a priority for the Android team, and we’re committed to building new safeguards to help prevent these kinds of attacks from happening in the future.
Tipstack till Joel!
