September 2nd: GO#WEBBFUSCATOR +++ Patches of the week

GO#WEBBFUSCATOR

Threat analysts form Securonix have spotted a new malware campaign dubbed GO#WEBBFUSCATOR which relies on phishing e-mails, malicious documents and most curiously on an image of the James Webb telescope. The malware is written in Golang, a programing language which is becoming increasingly popularfor cybercrime thanks to its cross-platform and its resistance to reverse engineering.

The malware starts its infection chain with a phishing e-mail which has a malicious .doxc file attached that downloads another file. Afterwards that file executes a macro which downloads another file, a JPG file. This is then decoded and executed. However, if the JPG file is opened with an ordinary program to view JPG data it only shows an image of the galaxy cluster SMACS 0723, published by NASA in July 2022.
