Fact-check findings

The reviewer could not reconcile the claim with the evidence it cited. This is a lead, not a ruling that the claim is false.

   “The infection exploited VS Code's tasks.json auto-execution feature: a hidden folder within the repository contained a configuration file that automatically ran pre-configured tasks when the workspace was opened in the editor, requiring no further user action beyond opening the folder.”

   reviewerThe tasks.json auto-execution exploit ran pre-configured tasks when the workspace was opened in the editor, requiring no further user action beyond opening the folder.The page attributes silent, zero-interaction auto-execution to 'VS Code's tasks.json' generically, but the cited Proofpoint report distinguishes VS Code (shows a trust dialog) from Cursor (executes silently). This overstates the risk for VS Code users and should be corrected to reflect the editor-specific behavior described in the source.
   Proposed correction (not yet applied)

   The infection exploited the tasks.json auto-execution feature shared by VS Code and Cursor: a hidden folder within the repository contained a configuration file with pre-configured tasks that ran when the workspace was opened in the editor; in Cursor this executed silently with no further user action, while VS Code displayed a trust prompt that required the victim to approve execution before the tasks would run.

   “Proofpoint's broader tracking of related North Korean campaigns, including Contagious Interview and DangerousPassword, noted that those two campaigns alone had collectively netted an alleged $37.5 million since January 1, 2026, though this figure was not attributed exclusively to UNK_DeadDrop.”

   reviewerProofpoint's broader tracking of Contagious Interview and DangerousPassword found those two campaigns had collectively netted an alleged $37.5 million since January 1, 2026.The dollar figure itself is consistent with widely-reported numbers, but the attribution of the underlying research to 'Proofpoint's broader tracking' appears incorrect; the figure originates from Elliptic's blockchain-forensics research, published separately from Proofpoint's UNK_DeadDrop report.
