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 system used to develop installers for the Windows operating system.
