Anonymous posted the hacking guide after the New York Times disclosed that the President still uses an“old, unsecured Android phone”, which is believed to be a Samsung Galaxy S3. In their tweet, they warned Trump of the dangers and mentioned that software bug called ‘Stagefright’ could be used to crack into his smartphone by any potential hacker. They wrote: “A Galaxy S3 does not meet the security requirements of a teenager, let alone the purported leader of the free world. “Without exaggerating, hacking a Galaxy S3 or S4 is the sort of project I would assign as homework for my advanced undergraduate classes.” Stagefright could be used to infect Trump’s smartphone if he was fooled into clicking on a malicious web link, Anonymous said. How Stagefright works To execute the malicious plan, you need the victim’s phone number. Once available, one can easily gain complete access on smartphones running Android versions older than Android 5.0.1. In older Android versions, background components, such as those used to play multimedia files, are implemented in the native C++ code instead of more secure languages such as Java. This leads to remote code execution vulnerabilities, which can be misused using various hacking methods, one of which is Stagefright. To run Stagefright on the victim’s phone, a hacker needs to send a specially crafted MMS message containing an.MP4 file. MMS files are automatically downloaded when an Android device is connected to the internet. The hacker will be able to execute harmful codes on the smartphone once the download is complete and compromise sensitive data. The hacker can then delete the MMS without the victim even finding it out. Anonymous has constantly tweeted against Trump and warned that it will be targeting him. “Alternatively, one could advertise malware on Brietbart and just wait for Trump to visit,” the hacktivists added.
