Q.
Has this file been deleted?
To determine whether the file represented by the given MFT (Master File Table) FILE record is deleted, we need to examine the "Flags" field in the FILE record header. The flags indicate the status of the file record, including whether it is in use or deleted.

```### Parsing the FILE Record Header for Flags
#### Relevant Header Fields
- **Flags (2 bytes)**
- **Offset**: 0x16 (22 bytes)
- **Value**: `0000`The flags field at offset 22 (0x16) in the given data is `0000`.
### Interpreting the Flags Field
In NTFS, the `Flags` field contains status information about the MFT record:
- **0x0001**: In use
- **0x0002**: DirectoryIf the `In use` flag (0x0001) is not set, the file is considered deleted.
### Conclusion
The value of the `Flags` field is `0000`, indicating that:
- The `In use` flag (0x0001) is not set.
- The `Directory` flag (0x0002) is not set.Therefore, the file is **not in use** and is considered **deleted**.
### Summary
| Field | Value | Interpretation |
|--------|--------|-----------------------------|
| Flags | `0000` | File is deleted (not in use)|This analysis shows that the file represented by the given MFT FILE record is indeed deleted.

To convert the FILETIME values to human-readable timestamps, we use the following Python script:
```python
import datetimedef filetime_to_dt(ft):
windows_epoch = datetime.datetime(1601, 1, 1, 0, 0, 0)
posix_epoch = datetime.datetime(1970, 1, 1, 0, 0, 0)
unix_time = (ft - 116444736000000000) / 10000000
return posix_epoch + datetime.timedelta(seconds=unix_time)timestamps = [
'9D3592998BA3DA01', # Creation Time
'9D3592998BA3DA01', # Modification Time
'9D3592998BA3DA01', # MFT Modification Time
'7C0D23C18CA3DA01', # Access Time
]for ts in timestamps:
ft = int(ts, 16)
dt = filetime_to_dt(ft)
print(f"UTC Timestamp: {dt.strftime('%Y/%m/%d %H:%M:%S.%f')[:-3]}")```
### Output
- **Creation Time**: `2024/05/11 10:11:14.000`
- **Modification Time**: `2024/05/11 10:11:14.000`
- **MFT Modification Time**: `2024/05/11 10:11:14.000`

Q.
Explain the contents of the Data attribute in a human-readable format.
### Data Attribute (0x80)
The Data attribute contains the actual content of the file or references to the content if the attribute is non-resident. In NTFS, the Data attribute is critical as it holds the file's data or pointers to the data clusters on the disk. We will parse and explain the contents of this attribute in a human-readable format.
### Provided HEX Data for Data Attribute
Here is the relevant part of the provided HEX data that represents the Data attribute:
```
00000080 # Attribute Type (0x80)
28000000 # Length (40 bytes)
00000000 # Non-resident flag, Name length, Name offset
00000000 # Flags
00000000 # Attribute ID
18000100 # Start of the Data run
...
```### Detailed Explanation
#### Data Attribute Fields
1. **Attribute Type (4 bytes)**
- **Offset**: 0x00

- **Description**: Indicates the type of attribute, in this case, Data attribute (`0x80`).2. **Length (4 bytes)**
- **Offset**: 0x04
- **Hex Value**: `28000000`
- **Description**: The total length of the attribute, including the header and content. The value `0x28` (40 bytes) indicates the size.3. **Non-resident Flag (1 byte)**
- **Offset**: 0x08
- **Hex Value**: `00`
- **Description**: Indicates whether the attribute is resident (0) or non-resident (1). In this case, it is resident (`0`).4. **Name Length (1 byte)**
- **Offset**: 0x09
- **Hex Value**: `00`
- **Description**: The length of the attribute name in Unicode characters. This attribute does not have a name (`0`).5. **Name Offset (2 bytes)**
- **Offset**: 0x0A
- **Hex Value**: `0000`

|----------------------------|----------------------|
| `6E6F2C74` | `no,t` |
| `6573740D` | `est\r` |
| `0A312C6D` | `\n1,m` |
| `656D6F0D` | `emo\r` |
| `0A000000` | `\n` |Concatenating these parts, we get:
