[Vol-users] Investigate around a memory area

Hi all, I'm quite sure that there is a "standard procedure" in order to investigate a specific area of the memory once you found something useful in a specific address, but my research on volatility doc does not help me much. Here the problem. I was able to find out with yarascan and -W option (Andrew and Michael, thanks again!), where the password of a specific app is stored (see after my signature for the complete yarascan output). From this output, I can see that the password is stored from address 0xb2f771f0. I would like to see: - what is stored before the password - if this memory area is related to a specific file In other words, I would like to investigate how the app stored the password hoping that the password is always store with some criteria. Of course, I have several memory dumps, with different passwords set. The yarascan outputs (that shows me only something *after *the password) do not help me. Thanks in advance for all your help, Massimo (Here is the yarascan output. The password set is "mypassword2016") Task: ject.otr.app.im pid 1691 rule r1 addr 0xb2f771f0 0xb2f771f0 6d 00 79 00 70 00 61 00 73 00 73 00 77 00 6f 00 m.y.p.a.s.s.w.o. 0xb2f77200 72 00 64 00 32 00 30 00 31 00 36 00 00 00 00 00 r.d.2.0.1.6..... 0xb2f77210 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0xb2f77220 00 00 00 00 43 04 00 00 f0 4a b5 b2 00 00 00 00 ....C....J...... 0xb2f77230 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0xb2f77240 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0xb2f77250 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0xb2f77260 08 ff f9 b2 00 00 00 00 00 00 00 00 78 df fa b2 ............x... 0xb2f77270 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0xb2f77280 38 47 ef b2 f0 e8 d8 b2 68 76 f7 b2 00 00 00 00 8G......hv...... 0xb2f77290 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0xb2f772a0 00 00 00 00 00 ed f1 b2 68 9c f9 b2 00 00 00 00 ........h....... 0xb2f772b0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0xb2f772c0 d8 e4 e2 b2 00 00 00 00 68 01 00 00 00 00 00 00 ........h....... 0xb2f772d0 00 00 00 00 ff ff ff ff ff ff ff ff ff ff ff ff ................ 0xb2f772e0 ff ff ff ff ff ff ff ff a6 02 00 80 68 01 00 40 ............h..@
