GuLoader Malware Using Malicious NSIS Executables to Target E-Commerce Industry

GuLoader Malware Using Malicious NSIS Executables to Target E-Commerce Industry

Feb 06, 2023 Cyber Attack / Endpoint Security
E-commerce industries in South Korea and the U.S. are at the receiving end of an ongoing GuLoader malware campaign, cybersecurity firm Trellix disclosed late last month. The malspam activity is notable for transitioning away from malware-laced Microsoft Word documents to NSIS executable files for loading the malware. Other countries targeted as part of the campaign include Germany, Saudi Arabia, Taiwan and Japan. NSIS , short for Nullsoft Scriptable Install System, is a script-driven open source tool used to develop installers for the Windows operating system. While attack chains in 2021 leveraged a ZIP archive containing a macro-laced Word document to drop an executable file tasked with loading GuLoader, the new phishing wave employs NSIS files embedded within ZIP or ISO images to activate the infection. "Embedding malicious executable files in archives and images can help threat actors evade detection," Trellix researcher Nico Paulo Yturriaga  said . Over the cours
BazarCall Call Back Phishing Attacks Constantly Evolving Its Social Engineering Tactics

BazarCall Call Back Phishing Attacks Constantly Evolving Its Social Engineering Tactics

Oct 11, 2022
The operators behind the BazaCall call back phishing method have continued to evolve with updated social engineering tactics to deploy malware on targeted networks. The scheme eventually acts as an entry point to conduct financial fraud or facilitate the delivery of next-stage payloads such as ransomware, cybersecurity company Trellix  said  in a report published last week. Primary targets of the latest attack waves include the U.S., Canada, China, India, Japan, Taiwan, the Philippines, and the U.K. BazaCall , also called BazarCall, first gained popularity in 2020 for its novel approach of distributing the BazarBackdoor (aka BazarLoader) malware by manipulating potential victims into calling a phone number specified in decoy email messages. These email baits aim to create a false sense of urgency, informing the recipients about renewal of a trial subscription for, say, an antivirus service. The messages also urge them to contact their support desk to cancel the plan, or risk gett
Critical RCE Bug Could Let Hackers Remotely Take Over DrayTek Vigor Routers

Critical RCE Bug Could Let Hackers Remotely Take Over DrayTek Vigor Routers

Aug 04, 2022
As many as 29 different router models from DrayTek have been identified as affected by a new critical, unauthenticated remote code execution vulnerability that, if successfully exploited, could lead to full compromise of the devices and unauthorized access to the broader network. "The attack can be performed without user interaction if the management interface of the device has been configured to be internet facing," Trellix researcher Philippe Laulheret  said . "A one-click attack can also be performed from within the LAN in the default device configuration." Filed under CVE-2022-32548, the vulnerability has received the maximum severity rating of 10.0 on the CVSS scoring system, owing to its ability to completely allow an adversary to seize control of the routers. At its core, the shortcoming is the result of a buffer overflow flaw in the web management interface ("/cgi-bin/wlogin.cgi"), which can be weaponized by a malicious actor by supplying spec
Researchers Disclose Critical Flaws in Industrial Access Controllers from HID Mercury

Researchers Disclose Critical Flaws in Industrial Access Controllers from HID Mercury

Jun 10, 2022
As many as four zero-day security vulnerabilities have been disclosed in the HID Mercury access controller system that's used widely in healthcare, education, transportation, and government facilities. "The vulnerabilities uncovered allowed us to demonstrate the ability to remotely unlock and lock doors, subvert alarms and undermine logging and notification systems," Trellix security researchers Steve Povolny and Sam Quinn said in a report shared with The Hacker News. The issues, in a nutshell, could be weaponized by a malicious actor to gain full system control, including the ability to manipulate door locks. One of the bugs (CVE-2022-31481) includes an unauthenticated remote execution flaw that's rated 10 out of 10 for severity on the CVSS scoring system. HID Mercury controllers, which feature highly flexible configurations, are utilized by over 20 OEM (original equipment manufacturer) partners to design and deploy a broad range of access control systems, with
