• 本次演講涵蓋了 Tesla Model X 免鑰匙進入系統的實用安全評估。我們將介紹系統的內部工作原理，包括密鑰卡、車身控制模組和配對協議。此外，我們還詳細介紹了我們的逆向工程技術並記錄了幾個安全問題。密鑰卡韌體更新機制和密鑰卡配對協議中已發現的問題使我們能夠繞過所有已實施的加密安全措施。我們的概念驗證攻擊可以在幾分鐘內解鎖並啟動 Model X。 Tesla 使用 OTA 更新修復了金鑰卡韌體更新機制中的漏洞。

• Source: https://stackoverflow.com/questions/3810722/datagridview-select-last-row
• I have some trouble with setting the last row in my datagridview selected. I select the last row this way:

  if (grid.Rows.Count > 0)
  {
      try
      {
          grid.Rows[grid.Rows.Count - 1].Selected = true;
          grid.CurrentCell = grid.Rows[grid.Rows.Count - 1].Cells[1]
      }
      catch (IndexOutOfRangeException)
      { }
      catch (ArgumentOutOfRangeException)
      { }
  }

• When I execute this code I get an exception:
  • IndexOutOfRangeException occurred: Index-1 does not have a value.
• When I debug the Rowscollection and the corresponding Cells collection I see both collections are filled. The index also exists of the Rows and Cells collection.
• I have no clue what I am doing wrong here. Someone who can help me out here? Thnx
