Key within square brackets in a JSON array

I am dealing with a JSON array that includes a square bracket in the key, like this:

{
  "msg":"OK",
  "data":[
    {
      "nls!type":"NCR",
      "current":"Assign",
      "physicalid":"0FFE0001000009FC5BD6805C00001352",
      "attribute[custTitle]":"Title",
      "name":"181002",
      "description":""
    }
  ]
}

My question is, how can I access the value of "attribute[custTitle]" in JavaScript?

When attempting to retrieve arrData[i].attribute[custTitle], I am encountering an error stating that custTitle is not defined. However, I am able to access the other values in a similar manner without any issues.
