An analysis of pre-installed apps on Samsung devices has revealed multiple security bugs which could have been exploited by attackers to spy on users and steal their data.<\/p>\n

The vulnerabilities were uncovered by mobile security company Oversecured<\/strong><\/a> and first reported by Hacker News<\/strong><\/a>.<\/p>\n

Oversecured spent two weeks looking for gaps in the security of these apps and discovered seven dangerous vulnerabilities.<\/p>\n

The bugs could have resulted in significant privacy violations, with hackers able to access sensitive communication on the users’ devices.<\/p>\n

“The impact of these bugs could have allowed an attacker to access and edit the victim\u2019s contacts, calls, SMS\/MMS, install arbitrary apps with device administrator rights, or read and write arbitrary files on behalf of a system user which could change the device\u2019s settings,” Oversecured said.<\/p>\n

The table below shows the apps in which the vulnerabilities were discovered as well as a description of what kind of attack they allowed.<\/p>\n

A detailed explanation of how Oversecured was able to exploit each of the vulnerabilities on a testing device can be found on its website<\/a><\/strong>.<\/p>\n

Samsung rolls out fixes<\/h3>\n

Oversecured reported the vulnerabilities to Samsung before revealing them to the public.<\/p>\n

Samsung labelled the severity of the vulnerabilities from moderate to high and included fixes for them in its April and May firmware updates.<\/p>\n

It also rewarded the company more than $20,500 for disclosing the bugs.<\/p>\n

It is recommended that Samsung device owners install the latest firmware updates to prevent falling victim to hackers looking to exploit these bugs.<\/p>\n
