8 We **strongly** urge you to [[upgrade to Tails 0.7|news/version_0.7]]
9 in case you are still using an older version.
13 # Incomplete "erase memory on shutdown" feature
15 As an [[external audit
16 demonstrated|security/audits/Blackhat_De-Anonymizing_Live_CDs]], the
17 "erase memory on shutdown" feature, as implemented in Tails 0.6.2 and
18 older, does not erase as much memory as it could. More specifically:
20 1. Parts of the memory that are still allocated at shutdown time are
21 not erased and can be recovered after shutdown; this includes the
22 entire in-memory filesystem (associated meta-data, content of files
23 created or modified since boot).
24 2. Partial recovery of deleted file names and their meta-data is also
27 This discovery lead to a brand new implementation of the memory
28 erasure feature that is shipped in Tails 0.7. As a bonus, the memory
29 is now also erased when the boot media is physically removed.
