Supply chain chaos is turning ugly as threat actors evolve their attack techniques. After the infamous SolarWinds attack, researchers have found a new supply chain attack targeting the Vietnam Government Certification Authority (VGCA). The attack was used to compromise the agency’s digital signature toolkit to install spyware called PhantomNet or Smanager on victims’ systems.

Meanwhile, giving a befitting reply to attackers behind SolarWind attacks, Microsoft, in collaboration with FireEye and GoDaddy, have created a killswitch for SUNBURST backdoor to disrupt the operations of the malware.

In other news, two malicious RubyGems packages and 28 malicious Chrome extensions were found stealing cryptocurrencies and users’ data respectively.

In a collaboration effort from Microsoft and GoDaddy, FireEye has created a killswitch for Sunburst malware that has reportedly infected SolarWinds’ Orion platform. The backdoor had impacted several U.S. government agencies and many private firms such as Boeing, AT&T, and Ford.

Malicious RubyGems package
Two new malicious RubyGems packages were taken down from the RubyGems repository for their participation in a supply chain attack designed to steal cryptocurrency from unsuspecting users. These packages masqueraded as a bitcoin library and a library for displaying strings with different color effects. They were named 'pretty_color-0.8.1.gem' and 'ruby-bitcoin-0.0.20.gem' and contained a malicious Ruby script that creates VBS scripts that act as clipboard hijackers.

Meyhod skimmer discovered

Elements of the code vary across different victim sites, with operators appearing to tailor them to match those used by each victim site.

Malicious extensions
Researchers have found around 28 malicious Chrome and Edge extensions that can allow attackers to steal users’ data and redirect victims to ads and phishing sites. These tainted extensions pose as helper add-ons for Vimeo, Instagram, Facebook, and other popular online services.
