What is BlotchyQuasar RAT

BlotchyQuasar RAT is a remote access Trojan (RAT) that provides cybercriminals with extensive control over infected systems. As a variant of QuasarRAT, it is designed to stealthily infiltrate computers and execute a range of malicious activities. This malware is capable of keylogging, executing shell commands, and monitoring user activities, especially those involving banking and payment services. It can capture sensitive information such as usernames, passwords, and credit card details by spying on browser and FTP client data. BlotchyQuasar is typically distributed via phishing emails containing malicious attachments or links. Once installed, it can also download additional malware, access Task Manager and Registry Editor, and manage system processes. The malware’s ability to remain undetected and its comprehensive feature set make it a significant threat to both individual users and organizations. Immediate removal and robust preventive measures are essential to mitigate the risks posed by BlotchyQuasar RAT.

How BlotchyQuasar RAT infected your system

BlotchyQuasar RAT typically infiltrates computers through sophisticated phishing email campaigns. These emails often contain a PDF attachment or a URL, both directing the victim to download a ZIP archive from a compromised Google Drive folder. Once the user opens the ZIP file, it reveals a .NET executable that, when executed, installs the BlotchyQuasar RAT on the system. This malware can then silently monitor user activities, steal sensitive information, and even deploy additional malicious software. Such attacks highlight the importance of exercising caution when interacting with unexpected emails and attachments.
