BS2005 is a malicious software (malware) traditionally used by a cybercriminal group for harmful activities. The malware infiltrates systems via suspicious downloads, emails, or websites and can steal personal information, disrupt operations, or hold data hostage for ransom. BS2005, known as a backdoor, communicates with the attacker's command and control (C2) through Internet Explorer using the COM interface IWebBrowser2. It leverages specific domains for C2 operations, causing significant security concerns. This malware has evolved over time, with its roots traced back to an earlier malware model called Flea backdoor Ketrican. Ketrican was based on BS2005, demonstrating the continuous development and sophistication of these threats. Recently, BS2005 has been observed to appear alongside additional backdoors RoyalCli and RoyalDNS. These new iterations represent advancements in the group's malware arsenal, increasing the potential damage they can cause. RoyalCli and RoyalDNS are notable evolutions of BS2005. They use familiar encryption and encoding routines, making them difficult to detect and mitigate. RoyalCli, like BS2005, also communicates with the attacker's C2 through Internet Explorer. The presence of these backdoors alongside BS2005 indicates an escalation in the threat landscape, necessitating more robust cybersecurity measures to counteract these sophisticated attacks.
