What is PO Copy email virus?
As a rule, malspam campaigns are used with a purpose to trick recipients into opening a malicious attachment or a file downloaded via malicious website that is designed to infect computers with a certain malware. In this particular case cyber criminals send emails with attached 7z archive file which contains a malicious Microsoft Office document designed to install Agent Tesla.
This email is disguised as a letter from Shyamsree Infrastructure PVT LTD, a non-government real estate company. It contains an attachment (the "PO Copy.7z" archive file) which supposedly is a purchase order (PO) copy. Although, that archive file contains a malicious MS Office document which is designed to install Agent Tesla. This malware is capable of functioning as a keylogger - it can record keyboard input, which means cyber criminals behind it may steal information such as credit card details, login credentials (usernames, passwords), and other sensitive, confidential data that could be misused to steal accounts, identities, make fraudulent purchases, transactions, etc. It is known that this Agent Tesla is capable of stealing information from a number of web browsers, email clients, messaging clients, VPN and FPT clients, various download managers. Also, newer Agent Tesla version can prevent victims from accessing Task manager, System Registry, launching Command Prompt and some of the other Windows features.
