Phishing attack leveraging SMS ban

 

Today morning was just about going as usual till I noticed an email. It seemed to originate from AXIS bank and it had an HTML attachment and it was an important announcement.

The contents of the email looked valid considering Government of India had placed a ban on sending of bulk SMS till 29th. Now I am not sure if such ban holds good for financial institutions. But some smart bloke seems to have capitalized on this ban. The email stated that:

“In view of the Govt. of India directive to mobile operators, all the corporate sms messaging services have been blocked for the next 72 hours. This period may increase. In view of this exigency, Axis Bank Net Secure Code and transaction alerts delivery has been effected. Therefore, till the Govt. of India permits restoration of the system. 

Axis Bank customers may not be able to conduct Internet Banking transactions that use SMS for delivering the NetSecure code. This is a regulation by Govt. of India and beyond Axis Bank’s control.

We have attached a form to this email. Please DOWNLOAD the form attached to this email so that you can fill and submit it Online to us , so that we can verify your account , After the Govt. of India permits restoration of the system. .
NOTE: The form needs to be opened in a modern browser which has javascript enabled ( Internet Explorer 7, Firefox 3, Safari 3, Opera 9)”

Now unlike the other phishing emails that I have encountered this one seemed different and the content (read grammar) also looks more in line from a professional agency and in tandem with the events that are happening in India.

This is the snapshot of the email:

 

Phishing Email targetting Axisbank

 

I opened the HTML attachment, after a customary scan from AV. Now although this looks authentic, but is a bit suspicious because it is asking for too many private details that should evoke second thoughts from anybody. Generally any phishing attack would ask for username, password, cvv details at the max. But this one is prompting for ATM PIN,Transaction password, Secure Code/Verified by Visa, Email details. And unlike others where you enter the details on a site, it is sending an attachment to be filled and submitted. Modus Operandi is slightly different.

I bet someone who is familiar with Axis bank’s online transaction mechanism has set this up because Axis bank requires transaction password in addition to the details mentioned above for a online transaction. Now, the form is a html attachment and when you open everything looks authentic just take a look below.

This is it, but once you look at the page source carefully you will realize the bait. Using the POST method, all details would go to the URL specified instead of Axis bank:

A Whois lookup for the domain above lists that is based out of Poland. All I can do is just notify Axis bank of this. It would have been better if the Government of India or the financial institutions have had made it clear if their services would continue to operate or be impeded due to this SMS ban.

Take care and please spread a word to ensure people do not fall for this

UPDATE:

I would have thought that the content in their email was written by a smart bloke, but it’s actually flicked from Axis Bank’s login page!

11 October

Received another Phishing email with the similar modus operandi , this time targeting ICICI Bank and hosted at:

    Can you please share the details . I am LEO ( Law Enforcement Officer ) . Our unit delas with similar crime. May be we would be able to pass this info to our counterparts in Polland , after we have prima facie found it to be phishing attack. can you forward mail at mentioned above.

  • mssbusybee

    Forwarding the email will lose all its header rendering it useless. If the header could be extracted and sent we could try to see where the email originated from.

  • prasanna

    Of-course it’s possible to retrieve the header and forward it. Just like the random domains used for hosting such phishing sites, the IP addresses used for sending such emails also change rapidly with time. According to Fraudwatch, the average uptime of a phishing site is 52 hours only!

    Your blog is exactly what I’ve been trying to get. It’s a very enlightening read. If every blogger would be as visitor specific as you, life could be so much easier.

    I wish more people would write blogs like this that are really fun to read. With all the fluff floating around on the net, it is rare to read a blog like this instead.
