Telstra Mimicked Again in New Phishing Scam

Telstra customers are being targeted once again in a new phishing scam which is landing in inboxes with the subject line “Telstra – Learn more about your account .” Telstra are frequently spoofed by scammers because of their large customer base and trusted name, like in these scams that we reported on earlier this year in March and May. If your business email is not secured with MailGuard, make sure to read on so that you don’t fall victim to this one.

The sender address shows “Service (No-reply)”, however the email comes from “service(at)servwork(dot)net”. The email has minimal branding, aside from the Telstra logo, and it begins with a generic “Hello”, before explaining that they have been “unable to process the payment of the last owing bill”. In order to fix that problem, the recipient is instructed that they must update the credit card on their account by clicking the hyperlinked text which says, “Open My Telstra”.

Here's what the email looks like:

Telstra - Learn more about your account . - Mozilla Thunderbird_943

 

After clicking the linked text, the user is taken to a ‘Sign in’ page which is craftily designed to replicate the one Telstra currently uses, however, you’ll notice the website is hosted on a domain called “hostenko(dot)net” which is a tell-tale sign that this is a phishing site.

The user is asked to enter their username and password before pressing ‘Sign in’

After proceeding, the user is instructed to enter their credit card details, including:

  • Name on card
  • Card number
  • Expiration date
  • CCV

This page retains much of the Telstra branding to make it feel more authentic.

Next, the user is instructed to enter their unique one-time code which has been sent to their mobile. Although their credit card details would already have been harvested from the last page, our team assumes that this would be used in an attempt to charge their card.

Once the code has been entered, the victim is shown a screen which states, “your invoice has been paid successfully” and they are then redirected to the legitimate Telstra homepage.

Telstra offers the following suggestions if you have received an email mimicking them:

  • Avoid opening suspicious or unsolicited emails – delete them directly from your inbox.
  • If you get a suspicious email, don't reply to the email or open the links. If you accidentally click on a link which opens a website, don't enter any information onto the website.
  • Avoid opening email attachments. If you've already saved or clicked on an attachment, make sure that your computer’s operating system and anti-virus software is up to date. Consider running an anti-virus scan of your computer.
  • Tell us about the scam by submitting a Report Misuse of Service form and include as much detail as you can. Our Cyber Security team will investigate the report and may be in touch if they have additional questions.
