ANZ Internet Banking.
This email, which purports to be from major Australian Bank, ANZ, claims that access to the recipient's online bank account has been revoked due to a large number of invalid login attempts. The recipient is advised to click a link in the message in order to login and restore account access.
However, the message is not from ANZ nor has the recipient's account access been revoked. In fact, the message is sent by Internet criminals and is designed to steal private bank account information from unsuspecting ANZ customers. Those who following the link in the scam email will be taken to a bogus web page created to closely resemble the genuine ANZ website. Once on the fake website, the customer will be asked to login with his or her Customer Registration Number and password. However, once entered, this login information can be subsequently collected by scammers. Armed with this login information, the scammers can then login to the customer's real ANZ account and steal money and account details at will.
ANZ has published information warning customers about such phishing scams on its website. Banks and other financial institutions are very unlikely to request customers to update information by following a link in an unsolicited email.
Phishing criminals generally send out identical scam messages to many thousands of email addresses in the hope that at least some of them will reach customers of the targeted institution, in this case ANZ. Even if only one or two of the thousands who receive the scam emails actually submit their banking information, the phishing attack will have well and truly paid off for the criminals who operate such schemes.
Although they may target many different financial institutions around the world, scammers continually reuse the same tricks. As in the above example, many phishing scams try to trick recipients into clicking a link by claiming that their accounts will be suspended until the requested account information is supplied. Many others claim that the user must update information urgently due to a recent security upgrade or hacking attempt.
Be very cautious of any unsolicited email that asks you to supply login or other personal information via a link or via an attached form. If in doubt, always check with your bank directly before submitting any information. It is good policy to always access your Internet Banking website by directly typing the address into your browser.
