DefenseStorm is aware of the recent campaign attributed to the Chinese APT group Lotus Blossom targeting Notepad++. We have collected, validated, and uploaded all currently available Indicators of Compromise (IOCs) and will continue to add additional IOCs as they are released publicly.
Based on the research made available, the organizations compromised appear to have been very targeted indicating that the presence of the vulnerable versions does not guarantee that all organizations are impacted. An initial investigation performed by the DefenseStorm CTS-OPS Team has not revealed any evidence of compromised thus far. The team will continue to investigate as more information is made available.
Below is the link to the official Notepad++ advisory, which includes their published details and recommended actions.
