Choose Smart Password for your online accounts and protect from hacking

Password is the first line of defense against cyber criminals. If you are using the same password on different websites allows hijackers to access your important accounts details like email, and bank details, if they manage to steal your password from a less secure website.   You're likely to have dozens of accounts across the web, and you can't guarantee the security of all of those accounts. Many smaller companies don't have security technology capable of guarding your data from cyber criminals. When you use the same password across the web, a cyber criminal can gain access to a less secure account and then use that password to compromise your important accounts.



To create a smart password try the following steps:

  • Use unique passwords for your accounts, especially important accounts like email and online banking. Re-using passwords is risky. If someone figures out your password for one service, that person could potentially gain access to your private email, address, and even your money. 

  • Using numbers, symbols and mixed-case letters in your password increases the difficulty of guessing or cracking your password. For example, there are more than 6 quadrillion possible variations for an eight-character password with numbers, symbols, and mixed-case letters - 30,000 times more variations than an eight-character password with only lowercase letters.  Do NOT use personal information such as birth dates, anniversaries, special events, etc. because if the hacker is a so-called friend of acquaintance, your password yells free information. Additionally the longer the pass word the more secure, 8 characters in length is acceptable but 14 is recommended.

  • Choose a combination of letters, numbers, or symbols to create a unique password that's unrelated to your personal information. Or, select a random word or phrase, and insert letters and numbers into the beginning, middle, and end to make it extra difficult to guess (such as "sPo0kyh@ll0w3En"). Using simple words or phrases like "password" or "letmein," keyboard patterns such as "qwerty" or "qazwsx," or sequential patterns such as "abcd1234" make your password easier to guess or crack.

  •  Make sure to regularly update your recovery email address so that you can receive emails in case you need to reset your password. You can also add a phone number to receive password reset codes via text message. Additionally, many websites (including Gmail) will ask you to choose a question to verify your identity if you ever forget your password. If you're able to create your own question, try to come up with a question that has an answer only you would know. The answer shouldn't be something that someone can guess by scanning information you've posted online in social networking profiles, blogs, and other places. If you're asked to choose a question from a list of options, such as the city where you were born, be aware that these questions are likely to be less secure. Try to find a way to make your answer unique — you can do this by using some of the tips above — so that even if someone guesses the answer, they won't know how to enter it properly.

  • Don't leave notes with your passwords to various sites on your computer or desk. People who walk by can easily steal this information and use it to compromise your account. If you decide to save your passwords in a file on your computer, create a unique name for the file so people don't know what's inside. Avoid giving the file an obvious name, such as "my passwords." If you have a difficult time remembering multiple passwords, a trusted password manager may be a good solution. Spend a few minutes checking out the reviews and reputations of these services.

E-mail accounts of embassies and Government offices across the world, including India hacked due to lack of Cyber Security

A hacker, Dan Egerstad from Sweden, who published passwords of 100 e-mail accounts of embassies and Government offices across the world, including India, on his website http://derangedsecurity.com. The hacker said he took only a few minutes to figure out the account details.

This shows that there is lack of basic cyber security. Due to the lack of security anyone with moderate skills in security could have figured this out and done it. A cyber security expert said that a POP (Post Office Protocol) server that had not been updated for security could have been exploited by the hacker to get usernames and passwords.

The Indian Express said in their website that they were sent a test mail to the Indian Ambassador in China on her official email ID and, using the password posted online, to check the authenticity and was able to access it. These email IDs contained important official details including phone numbers, commercial documents, official correspondence and personal mails.

Within hours of the story appearing in the Indian Express, the DRDO mail server was shut down and all embassy e-mail accounts were taken offline by the Ministry of External Affairs (MEA). However, it will take cyber forensic experts several days to get an idea of how much confidential material was illegally accessed.

DRDO confirmed that the hacked account belonged to a Defense Scientific Information and Documentation Centre (DESIDOC) official, but it was rarely used. The Ministry of Defense (MoD), however, said it was conducting a detailed investigation into the incident.

iPhone Hacked Successfully - Security Firm Says

iPhone Hacked Successfully - Security Firm Says

A vulnarabilty has found in the Apple Inc.'s iPhone handset that can help an attacker to gain access to the private data stored on it. This flaw has found by a team of security expert of Independent Security Evaluators (ISE). Hackers could gain access to the iPhone through a wireless access point or through a website controlled by the attacker. This was the first major security incident reported.

Numerous hackers have been working to gain access to the iPhone in order to activate certain features or to allow it to be used on cellular networks. However, this is the first major exploitation of an iPhone security flaw.

The expolit is delivered via a malicious web page opened in the Safari browser on the iPhone, ISE said on its Website. There are several methods that an attacker utilize to get a victim to open such a webpage.

1. An attacker controlled wireless access point:

The iPhone connects to wireless Internet access networks, such as Wi-Fi, an attacker could create a network with the same name and encryption method as one the handset already uses. The attacker could then substitute a Web page with exploit code to gain access to the phone.

2. A misconfigured forum website:

A link planted on an unedited or unmoderated online forum, an attacker could cause the exploit to run in any iPhone browser that viewed the thread.

3. A link delivered via e-mail or SMS:

A link sent by SMS or e-mail to use make use of the flaw and gain access to the handset.

The ISE said that when the iPhone's Safari browser opens a malicious Web page, malicious code can be run on the phone via the flaw, allowing the attacker to read the iPhone's SMS log, address book, call history, and voicemail information, which are also then sent to the attacker. It could send the user's mail passwords to the attacker, send text messages that sign the user up for pay services, or record audio that could be relayed to the attacker.
