Virus analysis report of "eavesdropping on ghosts"I. Introduction
Baidu's security lab has found a "eavesdropping ghost" virus. This virus is a eavesdropping spyware that monitors user privacy in the following ways: Obtain the initial password through the QQ space; install the virus software on the mobile phone of the monitored party, use the initial password to log on to the software and run it in the background. The monitoring Party sends various text message commands, and the spyware sends a
IMSI is the only one that corresponds to SIM.The IMEI is also a unique number that identifies the only mobile phone in the GSM and UMTS networks. It is usually printed on the side of the battery below the cell phone and dials * #06 # to see it. The IMEI corresponds to the device only.1. The IMEI does not exist in the SIM card, it is the serial number of the phon

electronic serial number. It is a unique constant number applied to CDMA mobile phones and is the self-identification during transmission in the communication system. A valid ESN is the hexadecimal number of an 8-digit number, for example, 0x11bb22ff. Note that 0x must be used as the prefix of ESN.
IMEI is the abbreviation of the international mobile device identification number International Mobile Equipment Identity. It is the serial number of the

Callbackfun () function, beginning is written if-if-else. The result is that the first if there is no match, it will be judged again,
If the second if is matched, the statement in the second if is executed, and the statement in else is executed if there is no match to the second if.

Today we will talk about some things of uiscrollview. This drag-and-drop component is often used in both application and game development, so we must be more familiar with it. Let's get started.
(1) initialization
Generally, you can use alloc and init to initialize components.CodeInitialization.
Uiscrollview * SV = [[uiscrollview alloc] initwithframe: cgrectmake (0.0, 0.0, self. View. Frame. Size. Width, 400)];
There are also many method
There are two types of requests: Form request submission and Ajax request.
We now read the returned results of these two requests.
Use our custom XML format in the background.
Then write a JS file to read the XML file.
1: Read the XML returned by the Ajax requestVaR ajaxread = {};Ajaxread = function (DOC ){This. xmldata = Doc;VaR root = doc.doc umentelement | Doc;VaR q = ext. domquery;VaR SV = Q. selectvalue ("success", root, true );Success =

Let's discuss the algorithm of coordinate transformation. A simple spatial transformation can be expressed using a transformation matrix:
[X', y', W'] = [U, V, W] * t
Here: X' and y' are the coordinates of the target image, and U and V are the coordinates of the source image. W and W' are called homogeneous coordinates, which are usually set to 1, T is a 3x3 transformation matrix.
Although this representation method is mathematical, it can be used
Sockpair Implementing interprocess communicationWe used to learn the use of pipelines (here is anonymous pipeline) to achieve interprocess communication, can only be one-way, can only read while the other side can only write, and can only be in a blood relationship between the process to communicate, if you want to achieve two-way communication must create two-way pipeline, and sockpair its implementation is two-way pipeline for communication. It can be used to create two-way communication pipel
(i.e. p (signal variable)) and send (i.e. V (signal variable)) information operation. The simplest semaphore is a variable of only 0 and 1, which is also the most common form of signal volume. Called binary semaphore. The number of signals that can take multiple positive integers is called a generic semaphore.The main discussion here is the binary signal volume.second, the operation principle of the signal volume because the semaphore can only perform two operation waits and sends the signal, n

The Su and SV values are the zooming rate in the X and Y axes respectively. If the value is greater than 1, The zooming rate increases. If the value is greater than 0, the zooming rate decreases when the value is smaller than 1, and if the value is less than 0, the zooming Rate.
Does the matrix look dizzy? In fact, the above formula is expanded by matrix multiplication:

A semaphore that can take multiple positive integers is called a generic semaphore.

Where the SU,SV is the X-axis direction and the Y-axis of the zoom rate, greater than 1 o'clock magnification, greater than 0 is less than 1 o'clock reduced, less than 0 when reversed.
The matrix is not looking faint. In fact, the above-matrix multiplication is:
{x = u * Su
{y = v * Sv
It's so simple. ^_^
