Cybercriminals Exploit Free Software Lures to Deploy Hijack Loader and Vidar Stealer

Cybercriminals Exploit Free Software Lures to Deploy Hijack Loader and Vidar Stealer

Jun 18, 2024 Malware / Cybercrime
Threat actors are luring unsuspecting users with free or pirated versions of commercial software to deliver a malware loader called Hijack Loader , which then deploys an information stealer known as Vidar Stealer . "Adversaries had managed to trick users into downloading password-protected archive files containing trojanized copies of a Cisco Webex Meetings App (ptService.exe)," Trellix security researcher Ale Houspanossian said in a Monday analysis. "When unsuspecting victims extracted and executed a 'Setup.exe' binary file, the Cisco Webex Meetings application covertly loaded a stealthy malware loader, which led to the execution of an information-stealing module." The starting point is a RAR archive file that contains an executable name "Setup.exe," but in reality is a copy of Cisco Webex Meetings's ptService module. What makes the campaign noteworthy is the use of DLL side-loading techniques to stealthily launch Hijack Loader (aka DOI...

A highly critical vulnerability has been discovered in the Cisco Systems' WebEx browser extension for Chrome and Firefox, for the second time in this year, which could allow attackers to remotely execute malicious code on a victim's computer. Cisco WebEx is a popular communication tool for online events, including meetings, webinars and video conferences that help users connect and collaborate with colleagues around the world. The extension has roughly 20 million active users. Discovered by Tavis Ormandy of Google Project Zero and Cris Neckar of Divergent Security, the remote code execution flaw (CVE-2017-6753) is due to a designing defect in the WebEx browser extension. To exploit the vulnerability, all an attacker need to do is trick victims into visiting a web page containing specially crafted malicious code through the browser with affected extension installed. Successful exploitation of this vulnerability could result in the attacker executing arbitrary code with th...
