The Glupteba botnet has been found to incorporate a previously undocumented Unified Extensible Firmware Interface (UEFI) bootkit feature, adding another layer of sophistication and stealth to the malware.

"This bootkit can intervene and control the [operating system] boot process, enabling Glupteba to hide itself and create a stealthy persistence that can be extremely difficult to detect and remove," Palo Alto Networks Unit 42 researchers Lior Rochberger and Dan Yashnik said in a Monday analysis.

"The identification of an undocumented UEFI bypass technique within Glupteba underscores this malware's capacity for innovation and evasion. Furthermore, with its role in distributing Glupteba, the PPI ecosystem highlights the collaboration and monetization strategies employed by cybercriminals in their attempts at mass infections."
