| Threats: | DCrat, also known as Dark Crystal RAT, is a remote access trojan (RAT), which was first introduced in 2018. It is a modular malware that can be customized to perform different tasks. For instance, it can steal passwords, crypto wallet information, hijack Telegram and Steam accounts, and more. Attackers may use a variety of methods to distribute DCrat, but phishing email campaigns are the most common. |
