“In each individual attack, the menace actor demonstrates intensive pink teaming expertise and the ability to bypass common antivirus detection applying their very own customized malware,” Group-IB’s Ivan Pisarev mentioned.
Energetic considering the fact that at the very least November 2018, the Russian-speaking RedCurl hacking team has been joined to 30 attacks to date with the intention of corporate cyber espionage and document theft aimed at 14 companies spanning development, finance, consulting, retail, insurance policies, and authorized sectors and positioned in the U.K., Germany, Canada, Norway, Russia, and Ukraine.
