2FA Effective Against Brute Force Password Guessing Attack Though latest technological advancements are benefiting companies and consumers, they are also empowering and encouraging hackers and thieves to develop new ways of invading your privacy. The facility of online banking transactions and making payments (using credit cards and debit cards) has definitely given you the leverage of completing your non-productive chores (paying bills, transferring money etc) while on the move thereby saving you significant time. But at the same time it has exposed your personal information to hackers who continue to find out ways to get illegal access to your information. If you're not attentive and careful, you may fall prey to their tricks and techniques at any time. It is not just a speculation. If it has already happened to you, understand it. And if it hasn't yet, learn from others. Twitter, Microsoft, Adobe, Apple – all found themselves at the receiving end of hackers' ire. The most recent example is GitHub, the popular software hosting service provider, which have suffered a brute-force password-guessing attack compromising some accounts. The company confirmed the news of attack on their official blog post. The post reads, the company had informed the users with compromised accounts through emails and had helped them with instructions to do the needful. While the company has reset users' passwords, it is asking its users to create new passwords. GitHub along with other leading MNCs and organizations including Facebook, Microsoft, Google, and Twitter advocate use of two factor authentication for preventing such hacking attempts. GitHub on the same blog recommends enabling two-factor authentication and a strong password. Let's discuss these two recommendations in detail: Choosing a Strong Password It's not the first time weak passwords have caused trouble to the users. Last month, Adobe suffered a hacker attack affecting around 38 million users, most of which were using simple and easily guessable passwords like ‘123456', ‘password', ‘123123' etc. Consider these tips while creating login passwords • Choose unique passwords for every account. Don't re-use the same password for two different accounts. It can be risky. • Reset your passwords regularly. It will help you block the unauthorized access to your account. • An ideal password is at least eight character long containing numbers, symbols and alphabets. • Don't choose a meaningful word or name of a person or place for the password. Rather, pick some random word or phrase by mixing alphabets, special characters and numbers in nonsensical order such as ‘lO@6Gh!)gM5'. It may be difficult for you to remember and it is secure against botnet attacks. • Make sure the password recovery system is secure and functional. • If you are keeping a database of passwords, keep it secure so that hackers can't reach to it. Add an extra security layer After you have created a strong login password for your account or database, you can add an extra security layer to it through two factor authentication. Most email (Gmail) and other email service providers provide the option of enabling 2-step verification or 2FA. For your personal accounts or databases you should contact a reliable 2 factor authentication service provider and get it implemented with immediate effect. 2FA is fast gaining popularity as an effective tool to block hacking attacks.
