Analysis of Camera 360 App privacy data leakage

Many popular Android applications have leaked private data. We found another popular Google Play app, "Camera 360 Ultimate", not only optimized users' photos, but also inadvertently leaked private data, allows malicious users to access their cloud accounts and photos of Camera 360 without being authenticated.

bad design: The entire article complained about how rotten PHP is.
Why does PHP suck? Another article similar to the one above.
Too much, really endless, if use in "Hacker News" and Reddit on a sentence summed up, that is:
Today to learn PHP, tomorrow will be eliminated directly.
See here, are you starting to question your choice of a bad programming language?
You know--it's all based on PHP.
Don't doubt your choice. Although it seems like everyone likes Clojure, Haskell and ja
how it is used to track memory leaks. After a memory leak occurs, the first step is to find out what data is leaked-Which class object causes the leakage? Jrockit memory leak detector is implemented by calculating the number of existing objects in each class during each garbage collection. If the number of objects in a specific class increases over time ("growth rate"), memory leakage may occur.

In 2014, it was another year in the history of network security, from large-scale leakage of Ctrip's credit card at the beginning of the year, to various open-source software vulnerabilities with strange names, then Sony was turned upside down by hackers. At the end of the year, hackers offered us a big dish-a credential stuffing event on the ticket Buying Network.

Because the leakage may be as small as a small stream, trend analysis must run for a long time. In a short period of time, some classes may increase locally,And then they will fall. However, the overhead of trend analysis is very small (the biggest overhead is to send data packets from jrockit to memory leak every t
statements in the Code and the fault code such as the result set is not closed or code redundancy.
The second step is to detect Java Memory leakage. Here we usually use some tools to check the memory leakage of Java programs. There are already several professional Java memory leak check tools on the market. Their basic working principles are similar. They are all through monitoring the application, release, and other actions of all objects when Java programs are running, collects, analyzes, and
