## Recon

The hint is persistence, so the first place to check in the reused backup is the user Startup folder:

```text
AppData/Roaming/Microsoft/Windows/Start Menu/Programs/Startup/
```

That folder contains an odd file:

```text
e9fje2.txt
```

## Solve

The file contents are base64:

```text
Q0lUe3N0NHJ0X20zX3VwX2kxMV9uM3Yzcl9zdDBwfQ==
```

Decoding it gives the flag directly:

```text
CIT{st4rt_m3_up_i11_n3v3r_st0p}
```

## Flag

```text
CIT{st4rt_m3_up_i11_n3v3r_st0p}
```
