Breaking security news: Email scam uses fakeTelstra branding to try and ambush recipients

A large run of malicious emails were detected and intercepted by our team. The scam email impersonates an electronic billing notification for Telstra customers and is quite well designed, and hard to distinguish from a real Telstra communication.
The scammers have made an effort to make this email look more legitimate by varying certain details, like the invoiced amount and the sender’s name.

This attack is ongoing, so if you receive an email claiming to be from Telstra today, be very cautious.

Another Javascript Based Email Attack

Similar to yesterday’s scam involving the fake invoice from a photography company, this email links the unwitting recipient to a hidden Javascript program. Emails of this type can be loaded with all kinds of malware including trojan horses, and spyware.

After clicking on the links in this email, thinking they were going to view their Telstra bill, the victim is directed to a Sharepoint folder containing the Javascript file. Victims might not immediately be aware they had been attacked, but the malware would be installed on their machines enabling the scammers to steal their data and take control of their computers.

One way this email can be identified as a scam is by looking at the actual email address behind the “Telstra” sender name. Instead of being real Telstra email addresses, they are from a wide variety of random looking mail domains, such as @sahara-group(dot)com, @stoneacre(dot)co(dot)uk, and @vialagro(dot)com(dot)ar.

What to Do if you Get a Scam Email?

If one of these fake Telstra emails reaches your inbox, delete it immediately.

If you are uncertain about the validity of a Telstra email, be sure to check the URL section of the sender's address - that’s the part after the @ symbol  - to ensure it is a legitimate Telstra communication.

Remember…

Always hover your mouse over links within emails and check the domain they’re pointing to. If they look suspicious or unfamiliar don’t open them.
