IPhone malicious worm is constantly looking for new "host"

Traditional common malicious code on the Internet, that is, we often mention the "worm", is looking for a new "host."

As mobile phones become increasingly powerful, malicious code attacks on a serious threat to these devices is growing, and computer criminals and further proof of this --- they used an improved version of iPhone (mobile Internet), the shortcomings, spread a programming theft Bank Information worms. Some experts said the worm may mark the invasion of criminals are more mobile devices access.

Crack version of iPhone has been a small number of "worms suffering"

Several researchers reported that the security firm, called "Ikee.B" or "Duh" of the new worm, can be installed on the iPhone using an improved version of the software's default password to spread. Once the equipment victim, the worm begins to crawl text messages, and search the bank for at least a bank authorization code, then the code sent to a central server. Earlier, another iPhone worms have appeared. Fortunately, it is only using the same password flaw to spread itself, but it does not attempt to steal personal information.

"The bank (attack) on the mobile device is very strange", antivirus company Sophos senior security consultant Charles Tovissi Kwasniewski (Chet Wisniewski) said. "It walk through your cell phone, get all your text messages and send them to a server in Lithuania."

It is understood that the worm will only cause inconvenience to a few people. Because of its attack affects only a small part of the content is modified, the software can be run on the ratified "cracked" version of iPhone. However, this does not mean that most of the iPhone is absolutely safe. Some researchers said the worm proved that their attacks can also "evolve" to harm more terminals. In addition, computer criminals are targeting portable devices, personal information and financial information to make such software more dangerous.

Smart phones more vulnerable

This summer, the Las Vegas Black Hat security briefing meeting, the Independent Safety Evaluation Association (IndependentSecurityEvaluators) consultant Charlie Miller (CharlieMiller) shows a cell phone text message to a remote attack by the methods iPhone. Miller said the goal of computer criminals to find out cell phone is only a matter of time, it will greatly expand the potential size of the virus.

"A more powerful worm will appear in Google's Android phones, Apple iPhone, and all other mobile phone. As more criminals involved in the invasion of how mobile phone platform, these devices will be attacked." Charlie m Le says.

Select smart phones, you should be prepared to bear such risk. iPhone and other smart phones, easily become a lawless molecular force's aim is similar to mini-computers --- they are often connected to the Internet, run third-party applications, and storage for computer criminals have the potential value of information.

Worms, all-pervasive

"Worms 'development' will continue." Miller said, although current research iPhone attack code, until a major outbreak of the worm is still a long way to go, such as the new worms are easily found, but in addition to the wireless network to transmit data, aggressive to infection than other phones, it can quickly consume the phone battery victims.

"Duh mentioned above Ikee.B or worm, the earliest dating back to 2000. To 2004, the first mobile phone worm Cabir special attack release. It can automatically between the Nokia Symbian mobile communication systems."

In 2006, the University of Toronto and Microsoft researchers showed that even among the close-and short-term mobile phone Bluetooth connection, in theory, can also be used for wireless worms. "Once the open Bluetooth, found loopholes in the outbreak of the worm is easy. An infected device in a busy shopping district in the city, in theory, can be opened by other Bluetooth-enabled mobile phones, to explore a large number of potential victims." Researchers so said.

Thief 3 of original experiences

Waited more than three weeks until the latest in a preferred game, when I saw the name of EIDOS have a sense of foreboding, because the killer to tell the truth 3 let me down, especially where the action is often floating immobile , Thief 3, the whole picture quite good, innovative ideas, which water arrows extinguish the torch very creative, but it is unsatisfactory in some areas,

First, if it is inconvenient to use the sword fighting, although the game is a dive, can, after all, a Grand Theft Auto, martial arts can not be too bad, silly action raised sword Lai Kan

Second, the task is unknown, I hit the second hurdle and soon took the three tasks are completed, as have marked the hook, but not the end, ran out the gates are not, and no training related tasks in So the task of escape, no way to town chaos pocket, do not know what treasures picked up, but also showed COMPLETE OBJECTIVE, Kuangyun

Third, the enemy AI is low, or even stuck in the door get out of the situation

These are my personal views and do not know how to play like you are welcome to correct me

Oh yes .. one attack action

Computer is very stupid ........ and cell. MGS2 computer AI than fully one day at a time!

I water shot computer, what did not. And you stick in the unconscious behind a computer, he did not wake up half a day, has been stunning!

But his shooting is still relatively new to this attack.

There are little tips, if you have been in the archery bow when the state, then suddenly back closer perspective.

Back to facilitate such a standard. Injective raise far the best things a little fire. This is not always the gun ....

To narrow the press "Z" on it, do not wait for it to automatically narrow the gap between ... ...

On close combat, it is stupid, swords and sticks like almost lethal, if not the enemy did not find, you can never face to face with these two weapons in the case of the blood does not hurt to kill him ~ at least I was In this way, I do not know how others ~ ~ ~

Considerate: Foxmail 6.0 beta 3 the beginning of experience

In mid-April, Foxmail 6.0 beta 3 (hereinafter referred to as beta 3) release. Although the functions do not have much progress, but still fine-tuning to do a lot of changes to become more useful new features. Here I take a look on the following, Foxmail 6.0 beta 3 to our pleasant surprise.

1, little change in the interface

First install Foxmail 6.0 beta 3, then start. From the start the interface point of view and the previous version does not change, only the version number into the beta2 beta3 (Figure 1). The main interface change is not great, and the previous version is almost no difference, but in some nuances have changed very little.



Figure 1 Foxmail 6 Beta 3 of the start interface

After some time I try, beta 3 performance in very stable, not been any problems. In the beta 2 version is not out of the bug can not be shut down have also been resolved.

In beta 1 the RSS reading functionality to add, in the beta 3 has been further improved. Personal use, and found the original information of the time to read RSS shortened from the original ten seconds reduced to only a few seconds, shortening the time to read the information to a third of the original. And author of Intelligent ABC input method previously used, and then run Foxmail, the main interface will appear flashing situation. Mailing list in the switching time, is also prone to flash the main interface. In the latest beta 3 version which was finally resolved this issue, no matter what the situation will not be the main interface Foxmail flashing on the other.

Second, build email address book automatically

In previous versions Foxmail among others the letter issued after the complete e-mail address is not automatically added to the address book are in need can be added manually. Other e-mail management software, such as DreamMail, e-mail address is automatically added to support the function. Fortunately enough the latest Foxmail 6.0 beta 3 which, I found that sending messages to others, the other's e-mail address is automatically added to the address book. Although you can add directly to the e-mail address, but only automatically adds email addresses, names need to be added manually before they can (Figure 2), so this feature appears to some tasteless. If we are to automatically add e-mail address at the time, also add the recipient's name the better.



Figure 2 automatically add the address also need to add the name

Third, the mailing list to allow return to the traditional style

Foxmail from 6.0 introduced a new mailing list style, so that messages can be grouped. Function is similar to Gmail messages automatically grouping. View the message can bring a lot of convenience. But not everyone likes. In previous versions of the list can not be restored to the traditional style, beta 3 to allow the mailing list to return to the traditional way. Through the menu "View" => "Show in Groups" option is canceled (Figure 3), so that the mailing list to restore the traditional style (Figure 4).



Figure 3 The new group mailing list



Figure 4 traditional mailing list

4, adjusted in order to support e-mail folder

New messages in the folder can Foxmail, will be charged to the letters of different people into different e-mail folder automatically. But e-mail folder is set up, can not change the location. In beta 3 in this case has changed. Can use the mouse to drag and drop e-mail folder, easily change their position, but not delete the re-established. In fact, this feature is very simple, do not know why-teng Xun the company achieved in this version only if the previous version have this feature, then I would not have so much trouble.

5, support for exporting, importing anti-spam black / white lists and Bayesian Popescu

Increased black / white lists and Bayesian Popescu is the biggest bright spot Foxmail 6.0. With it, you need not worry about spam. A previous version of the greatest shortcoming, it is unable to import the bulk black / white lists and Bayesian Popescu, can automatically be updated. This is not very user friendly.

beta 3 to change this situation, you can find the latest Bayeux Popescu online listings and their own definitions of black / white list into Foxmail in. Can also click on the "Export" button to the existing black / white lists and Bayesian Popescu back up or share with them their own Bayeux Popescu.



Figure 5 Bayesian filtering the relevant settings

6, write e-mail address auto-completion feature enhanced

Used IE's friends all know that when typing the URL in the address bar, IE will automatically display and type characters to match the address, this is IE's "auto complete" feature. Beta 3 also increased in a similar function. When you enter e-mail address, just enter a letter before the message will automatically add the e-mail the next section (Figure 6) to facilitate input-mail address.



Figure 6 Enter e-mail address auto-completion time

But do a little less than that if you want to write the address did not want people to know, Foxmail 6.0 beta 3 This new feature will disclose his secret, and can not be deleted, unless we can re-install Foxmail. This new feature seems to have convenient side and inconvenient side, If we are able to choose whether to auto-completion on the mailing list like a, so that it can effectively protect our privacy.

7, in the scrap box to delete messages, delete messages from the server at the same time

When we set up accounts, they usually choose to accept messages from the server and remain on the server, this way both in Foxmail in any operation, the server will not be changed. But the message we received when Foxmail receive some junk mail, usually is to delete these spam messages. But by the above settings, just delete Foxmail, and not on the server to delete. In Foxmail 6.0 beta 3 can be by setting, in the scrap box to delete messages at the same time from the server to delete the corresponding message.

In Foxmail 6.0 beta 3 settings, select General, then in the following "in the scrap box to delete messages from the server at the same time remove the corresponding message" stamped in front of a pigeon (Figure 11), so remove the scrap pieces of boxes in which the message When the mail server to delete the same time. But I recommend you this feature to be used with caution, because once deleted can not be restored.

Summary:

On the whole Foxmail 6.0 beta 3 at the interface is not much change in functionality is also no major changes. But there are many nuances have been changed, from this point of view to work out the strict attitude of Tencent. All this is only beta version of it, I believe the official version in Foxmail 6.0 will have more improvements, more complete, more powerful. Here I hope Foxmail farther good, get more people to love.
