32 * MSI advertised shortcuts are totally undocumented. They provide an
33 * icon for a program that is not yet installed, and invoke MSI to
34 * install the program when the shortcut is clicked on. They are
35 * created by passing a special string to SetPath, and the information
36 * in that string is parsed an stored.

39 * In the following is listed more documentation about the Shell Link file format,
40 * as well as its interface.
41 *
42 * General introduction about "Shell Links" (MSDN):
43 * https://msdn.microsoft.com/en-us/library/windows/desktop/bb776891(v=vs.85).aspx
44 *
45 *
46 * Details of the file format:
47 *
48 * - Official MSDN documentation "[MS-SHLLINK]: Shell Link (.LNK) Binary File Format":
49 * https://msdn.microsoft.com/en-us/library/dd871305.aspx
50 *
51 * - Forensics:
52 * http://forensicswiki.org/wiki/LNK
53 * http://computerforensics.parsonage.co.uk/downloads/TheMeaningofLIFE.pdf
54 * https://ithreats.files.wordpress.com/2009/05/lnk_the_windows_shortcut_file_format.pdf
55 * https://github.com/libyal/liblnk/blob/master/documentation/Windows%20Shortcut%20File%20(LNK)%20format.asciidoc
56 *
57 * - List of possible shell link header flags (SHELL_LINK_DATA_FLAGS enumeration):
58 * https://msdn.microsoft.com/en-us/library/windows/desktop/bb762540(v=vs.85).aspx
59 * https://msdn.microsoft.com/en-us/library/dd891314.aspx
60 *
61 *
62 * In addition to storing its target by using a PIDL, a shell link file also
63 * stores metadata to make the shell able to track the link target, in situations
64 * where the link target is moved amongst local or network directories, or moved
65 * to different volumes. For this, two structures are used:
66 *
67 * - The first and oldest one (from NewShell/WinNT4) is the "LinkInfo" structure,
68 * stored in a serialized manner at the beginning of the shell link file:
69 * https://msdn.microsoft.com/en-us/library/dd871404.aspx
70 * The official API for manipulating this is located in LINKINFO.DLL .
71 *
72 * - The second, more recent one, is an extra binary block appended to the
73 * extra-data list of the shell link file: this is the "TrackerDataBlock":
74 * https://msdn.microsoft.com/en-us/library/dd891376.aspx
75 * Its purpose is for link tracking, and works in coordination with the
76 * "Distributed Link Tracking" service ('TrkWks' client, 'TrkSvr' server).
77 * See a detailed explanation at:
78 * http://www.serverwatch.com/tutorials/article.php/1476701/Searching-for-the-Missing-Link-Distributed-Link-Tracking.htm
79 *
80 *
81 * MSI installations most of the time create so-called "advertised shortcuts".
82 * They provide an icon for a program that may not be installed yet, and invoke
83 * MSI to install the program when the shortcut is opened (resolved).
84 * The philosophy of this approach is explained in detail inside the MSDN article
85 * "Application Resiliency: Unlock the Hidden Features of Windows Installer"
86 * (by Michael Sanford), here:
87 * https://msdn.microsoft.com/en-us/library/aa302344.aspx
88 *
89 * This functionality is implemented by adding a binary "Darwin" data block
90 * of type "EXP_DARWIN_LINK", signature EXP_DARWIN_ID_SIG == 0xA0000006,
91 * to the shell link file:
92 * https://msdn.microsoft.com/en-us/library/dd871369.aspx
93 * or, this could be done more simply by specifying a special link target path
94 * with the IShellLink::SetPath() function. Defining the following GUID:
95 * SHELL32_AdvtShortcutComponent = "::{9db1186e-40df-11d1-aa8c-00c04fb67863}:"
96 * setting a target of the form:
97 * "::{SHELL32_AdvtShortcutComponent}:<MSI_App_ID>"
98 * would automatically create the necessary binary block.
99 *
100 * With that, the target of the shortcut now becomes the MSI data. The latter
101 * is parsed from MSI and retrieved by the shell that then can run the program.
102 *
103 * This MSI functionality, dubbed "link blessing", actually originates from an
104 * older technology introduced in Internet Explorer 3 (and now obsolete since
105 * Internet Explorer 7), called "MS Internet Component Download (MSICD)", see
106 * this MSDN introductory article:
107 * https://msdn.microsoft.com/en-us/library/aa741198(v=vs.85).aspx
108 * and leveraged in Internet Explorer 4 with "Software Update Channels", see:
109 * https://msdn.microsoft.com/en-us/library/aa740931(v=vs.85).aspx
110 * Applications supporting this technology could present shell links having
111 * a special target, see subsection "Modifying the Shortcut" in the article:
112 * https://msdn.microsoft.com/en-us/library/aa741201(v=vs.85).aspx#pub_shor
113 *
114 * Similarly as for the MSI shortcuts, these MSICD shortcuts are created by
115 * specifying a special link target path with the IShellLink::SetPath() function,
116 * defining the following GUID:
117 * SHELL32_AdvtShortcutProduct = "::{9db1186f-40df-11d1-aa8c-00c04fb67863}:"
118 * and setting a target of the form:
119 * "::{SHELL32_AdvtShortcutProduct}:<AppName>::<Path>" .
120 * A tool, called "blesslnk.exe", was also provided for automatizing the process;
121 * its ReadMe can be found in the (now outdated) MS "Internet Client SDK" (INetSDK,
122 * for MS Windows 95 and NT), whose contents can be read at:
123 * http://www.msfn.org/board/topic/145352-new-windows-lnk-vulnerability/?page=4#comment-944223
124 * The MS INetSDK can be found at:
125 * https://web.archive.org/web/20100924000013/http://support.microsoft.com/kb/177877
126 *
127 * Internally the shell link target of these MSICD shortcuts is converted into
128 * a binary data block of a type similar to Darwin / "EXP_DARWIN_LINK", but with
129 * a different signature EXP_LOGO3_ID_SIG == 0xA0000007 . Such shell links are
130 * called "Logo3" shortcuts. They were evoked in this user comment in "The Old
131 * New Thing" blog:
132 * https://blogs.msdn.microsoft.com/oldnewthing/20121210-00/?p=5883#comment-1025083
133 *
134 * The shell exports the API 'SoftwareUpdateMessageBox' (in shdocvw.dll) that
135 * displays a message when an update for an application supporting this
136 * technology is available.
