MagicWeb: NOBELIUM’s post-compromise trick to authenticate as anyone_Microsoft Security Blog

Microsoft security researchers have discovered a post-compromise capability we’re calling MagicWeb, which is used by a threat actor we track as NOBELIUM to maintain persistent access to compromised environments. NOBELIUM remains highly active, executing multiple campaigns in parallel targeting government organizations, non-governmental organizations (NGOs), intergovernmental organizations (IGOs), and think tanks across the US, Europe, and Central Asia. The Microsoft Threat Intelligence Center (MSTIC) assesses that MagicWeb was likely deployed during an ongoing compromise and was leveraged by NOBELIUM possibly to maintain access during strategic remediation steps that could preempt eviction.
