Samsung Galaxy S4 Launched in India for Rs 41,500

The Samsung Galaxy S4 launched in India today, for a price of Rs 41,500, which is very close to the indian price of it’s main rival, the HTC One.

The Galaxy S4 continues Samsung’s tradition of packing a big screen and a ton of high-end internals in a glossy plastic body accompanied by a front button array that dates back to Android 2.3, with a 5-inch 1080p Super AMOLED display with super-sensitive touch, a 13-megapixel rear-facing camera, 2GB of RAM, 16GB of internal storage (with 32GB and 64GB variants), a user-replaceable 2600mAh battery, a microSD card slot and the usual suspects: Bluetooth 4.0, MHL, WiFi and an IR transmitter. The device runs Android 4.2 Jelly Bean.

The Indian Galaxy S4 features an Exynos 5 Octa chipset (that’s an 8-core CPU with 4 cores clocked at 1.2GHz and another 4 cores clocked at 1.8GHz), instead of the Qualcomm Snapdragon 600 version with LTE that’s sold in Singapore and Australia.

Available in stores from this weekend, available at Samsung India’s e-store from 26/04/2013.

Password Cracking:John The Ripper

John the Ripper is a free password cracking software tool. Initially developed for the UNIX operating system, it currently runs on fifteen different platforms (eleven architecture-specific flavors of Unix, DOS, Win32, BeOS, and OpenVMS). It is one of the most popular password testing and breaking programs as it combines a number of password crackers into one package, autodetects password hash types, and includes a customizable cracker. It can be run against various encrypted password formats including several crypt password hash types most commonly found on various Unix flavors (based on DES, MD5, or Blowfish), Kerberos AFS, and Windows NT/2000/XP/2003 LM hash. Additional modules have extended its ability to include MD4-based password hashes and passwords stored in LDAP, MySQL, and others.

TYPES OF ATTACKS

• One of the modes John can use is the dictionary attack. It takes text string samples (usually from a file, called a wordlist, containing words found in a dictionary), encrypting it in the same format as the password being examined (including both the encryption algorithm and key), and comparing the output to the encrypted string. It can also perform a variety of alterations to the dictionary words and try these. Many of these alterations are also used in John's single attack mode, which modifies an associated plaintext (such as a username with an encrypted password) and checks the variations against the encrypted hashes.
• John also offers a brute force mode. In this type of attack, the program goes through all the possible plaintexts, hashing each one and then comparing it to the input hash. John uses character frequency tables to try plaintexts containing more frequently used characters first. This method is useful for cracking passwords which do not appear in dictionary wordlists, but it does take a long time to run.

What Is Shoulder Surfing??

You all must have heard of internet surfing, channel surfing, wave surfing but have you ever heard of Shoulder Surfing???
Well shoulder surfing refers to using direct observation techniques, such as looking over someone's shoulder, to get information. It is commonly used to obtain passwords,PINs, security codes, and similar data.

A survey of IT professionals found that:

• 85% of those surveyed admitted to seeing sensitive information on screen that they were not authorised to see
• 82% admitted that it was possible information on their screens could have been viewed by unauthorised personnel
• 82% had little or no confidence that users in their organisation would protect their screen from being viewed by unauthorised people.

Keystroke Logging

Keystroke logging, often referred to as keylogging, is the action of recording the keys struck on a keyboard, so that the person using the keyboard is unaware that their actions are being monitored. It also has very legitimate uses in studies of human-computer interaction. There are numerous keylogging methods, ranging from hardware and software-based approaches to acoustic analysis.

There are many counter measures for key logging such as One Time Passwords (OTP's), Anti Keylogger Softwares etc. For more information on this topic click on the above link.

Red Screen Of Death!!!

The Red Screen of Death, or occasionally The Red Screen of Doom (abbreviated RSOD) is another kind of error message. It existed in some beta versions (specifically Build 5048) of Microsoft's operating system Windows Vista. It is interesting to note that execution is incorrectly spelled "exectuion."

Trojan Horses

A Trojan horse, or Trojan, is a non-self-replicating type of malware which appears to perform a desirable function but instead drops a malicious payload, often including a backdoor allowing unauthorized access to the target's computer. These backdoors tend to be invisible to average users. Trojans do not attempt to inject themselves into other files like a computer virus. Trojan horses may steal information, or harm their host computer systems. Trojans may use drive-by downloads or install via online games or internet-driven applications in order to reach target computers. The term is derived from the Trojan Horse story in Greek mythology because Trojan horses employ a form of “social engineering,” presenting themselves as harmless, useful gifts, in order to persuade victims to install them on their computers.

Some operations performed by Trojan Horses are as follows:

• Modification or deletion of files
• Keystroke logging
• Watching the user's screen
• Viewing the user's webcam
• Controlling the computer system remotely
• Anonymizing remote third-party internet viewing

Task Manager

In this post I will show you the different ways to open task manager in Windows.

There are three different ways to open Task Manager in Windows OS.

1. The most common way, which is used by most of us is, using Ctrl + Alt + Delete. This opens a  new window from where we start the Task Manager.
2. The second method is by right clicking on the taskbar and clicking on the Task Manager option on the pop-up menu which opens up.
3. This is a very rare and mostly unknown method. This is a direct short-cut. We can open task manager by using Ctrl + Shift + Esc.

1.Never click on any link which came from an unknown sender saying to click here, click or click there!

2.If you clicked on a link and if you get redirected to a login page, then do these steps,

-Check the url, if its a login page of gmail, then the url should look like this http://www.gogle.com/account/xxxxxx
but, if url is different, then never login, its clearly a phishing page!

-When you open that type of page, dont forgot to see the certificate of that page, because a fake page never carry a certificate
To view a site certificate click on the logo before the url (It is a LOCK in case of Chrome)

Phishing

Phishing is the act of attempting to acquire information such as usernames, passswords, and credit card details (and sometimes, indirectly, money) by masquerading as a trustworthy entity in an electronic communications. Communications purporting to be from popular social web sites, auction sites, online payment processors or IT administrators are commonly used to lure the unsuspecting public. Phishing emails may contain links to websites that are infected with malware Phishing is typically carried out by e-mail spoofing or instant messaging, and it often directs users to enter details at a fake website whose look and feel are almost identical to the legitimate one. Phishing is an example of social engineering techniques used to deceive users.

In my next post I will teach you how to protect yourself from phishing.
