A new Trojan called Evrial is being sold on criminal forums and being actively distributed in the wild. Like most Trojans, Evrial can steal browser cookies and stored credentials, but this Trojan also has the ability to monitor the Windows clipboard for certain text, and if detected, modify it to something else.
First discovered and tracked by security researchers MalwareHunterTeam and Guido Not CISSP, by monitoring the Windows clipboard for certain strings, Evrial makes it easy for attackers to hijack cryptocurrency payments and Steam trades. This is done by replacing legitimate payment addresses and URLs with addresses under the attacker's control.
According to MalwareHunterTeam, Evrial is currently being sold on Russian criminal forums for 1,500 Rubles or ~ $27 USD. It is stated that after purchasing the product, an attacker gains access to a web panel that allows them to build an executable program.

When Evrial detects a bitcoin address in the clipboard, it replaces that legitimate address with one under the attacker's control. Then the victim pastes that address into their app and clicks send. Now when the bitcoins are sent, they go to the attackers address rather than your intended recipient.
Evrial is also configured to detect strings that correspond to bitcoin, litecoin, monero, WebMoney, Qiwi addresses and Steam items trade urls.
In addition to monitoring and modifying the clipboard, Evrial will also steal bitcoin wallets, stored passwords, documents from the victim's desktop, and a screenshot of the active windows. All of this information will be compiled into a zip file and uploaded to the attackers web panel.
