Be wary of a Telstra phishing email doing the rounds. The email advises the recipient that their latest Telstra bill is available to download. Upon clicking the link you will be presented with a zip file containing a malicious javascript file. This javascript file, when run, will download a Trojan onto your PC.  A Trojan allows an attacker to remotely access your PC. This allows an attacker to possibly view what you are doing, steal passwords, or install other malware, such as ransomware onto your PC.
