5 | 8 | laforge | Osmocom SIMtrace 2 is a software, firmware and hardware system for passively tracing SIM-ME communication between the SIM card and the mobile phone, and remote SIM operation. |
6 | 9 | tsaitgaist | While it was designed for SIM-ME communication, it supports all ISO 7816 smart-cards using the T=0 protocol (the most common case). |
7 | 1 | tsaitgaist | |
8 | 16 | roh | It is a followup of the "SIMtrace project":/projects/simtrace/wiki, providing more functionalities (e.g. remote SIM operation) and supporting multiple boards (e.g. SIMtrace with SAM3S, "sysmoQMOD":https://www.sysmocom.de/products/sysmoqmod/index.html). |

10 | h2. Hardware |
||
11 | |||
12 | 10 | tsaitgaist | The SIMtrace 2 firmware supports several boards. |
13 | The firmware is written for an "ATSAM3S4B":https://www.microchip.com/wwwproducts/en/ATSAM3S4B micro-controller. |
||
14 | 1 | tsaitgaist | |
15 | 12 | tsaitgaist | Note: The SAM3S is meanwhile labelled as _not recommended for new designs_ by Atmel. However, there are plenty of hardware and software compatible upgrade options, including SAM4S. The upgrade is possible in the future. |

20 | 9 | tsaitgaist | |
21 | 10 | tsaitgaist | The main purpose of this board is to sniff the communication between a phone and a SIM card (or any card reader and smart-card). |
22 | 1 | tsaitgaist | |
23 | 17 | roh | This is the same circuit board as the previous "SIMtrace v1":/projects/simtrace/wiki/SIMtrace_Hardware, with the exception that the "ATSAM3S4B":https://www.microchip.com/wwwproducts/en/ATSAM3S4B micro-controller replaces the old "AT91SAM7S64":https://www.microchip.com/wwwproducts/en/AT91SAM7S64. Since the SAM3S is pin compatible with the SAM7S, any SIMtrace v1 board can be converted into a SIMtrace v2 board simply by replacing the micro-controller. |

||
32 | |||
33 | !{width:25%}ngff-cardem.jpg! |
||
34 | |||
35 | This is a carrier board for cellular modems in ngff / M.2 form-factor with on-board simtrace2. It is wired in a way that it can operate both as passive tracer/sniffer, or in @cardem@ mode. |
||
36 | |||

50 | The SAM3S micro-controller with SIMtrace 2 firmware is also used on the "sysmoQMOD":https://www.sysmocom.de/products/sysmoqmod/index.html board to provide remote SIM operation capabilities. |
||
51 | |||
52 | Note: This hardware is not open source. |

58 | h2. Firmware |
||
59 | |||
60 | 10 | tsaitgaist | The SIMtrace 2 firmware source code is available in "git":https://git.osmocom.org/simtrace2/. |
61 | 20 | tsaitgaist | Pre-built firmware binaries are available "here":http://ftp.osmocom.org/binaries/simtrace2/firmware/. |
62 | The firmware are currently under active development and we recommend to [[Flashing|flash]] the new firmware images to profit from the latest bug fixes and added functionalities. |
||
63 | 1 | tsaitgaist | |
64 | The SIMtrace 2 firmware is a complete rewrite and *can only be flashed on hardware with SAM3S* ARM Cortex-M3-based micro-controllers. |
||
65 | 18 | roh | *The SIMtrace 2 firmware is not compatible with the older "SIMtrace v1":/projects/simtrace/wiki/SIMtrace_Hardware using SAM7S ARM7TDMI-based micro-controllers.* |
66 | 1 | tsaitgaist | |
67 | 35 | laforge | To get the version of the firmware flashed on the device, you can use the @simtrace2-list@ tool |
68 | 23 | tsaitgaist | |
69 | 12 | tsaitgaist | h3. trace |
70 | 1 | tsaitgaist | |
71 | 12 | tsaitgaist | The trace application firmware allow to sniff the communication between a phone and a SIM card (or any card reader and smart-card). |
72 | It is intended for the [[Wiki#SIMtrace v2|SIMtrace v2 hardware]] and its function is analog to the "SIMtrace v1":/projects/simtrace/wiki/SIMtrace_Firmware. |
||
73 | 10 | tsaitgaist | |
74 | 12 | tsaitgaist | The sniffing is completely passive. It uses the RST, ATR, PPS (baud rate tested with F/D up to 512/32), and WT (waiting timeout) to properly parse the ISO 7816-3 TPDUs. |
75 | Currently only the T=0 protocol is supported since this is the most common protocol used (we haven't seen T=1 in use). |
||
76 | |||
77 | 1 | tsaitgaist | !{width:25%}simtrace_and_phone.jpg! |
78 | 10 | tsaitgaist | |
79 | 20 | tsaitgaist | The application firmware to be flashed using [[Flashing#DFU|DFU]] is "simtrace-trace-dfu.bin":http://ftp.osmocom.org/binaries/simtrace2/firmware/simtrace-trace-dfu.bin. |
80 | 10 | tsaitgaist | |
81 | 24 | tsaitgaist | h3. card emulation |
82 | |||
83 | 25 | tsaitgaist | The card emulation application firmware allows to emulate a card (e.g SIM). This is useful if you don't want to change the card in the device (e.g. phone), or have the card in a remote location. |
84 | 24 | tsaitgaist | |
85 | This firmware comes preflashed on the sysmoQMOD board. |
||
86 | 1 | tsaitgaist | It also exists from the SIMtrace v2 board, but is currently in beta. If you still would like to try it, read this [[Cardem|article]]. |
87 | 25 | tsaitgaist | |
88 | 13 | tsaitgaist | h3. Development |
89 | |||
90 | To compile the firmware using the source code, or participate in the development, please refer to the instructions provided in the "README":https://git.osmocom.org/simtrace2/tree/firmware/README.txt . |
||
91 | |||
92 | 10 | tsaitgaist | h2. Flashing |
93 | 11 | tsaitgaist | |
94 | 1 | tsaitgaist | The [[Wiki#Firmware|firmware images]] can be flashed as described [[Flashing|here]]. |

100 | 33 | laforge | Binary packages are made available for a variety of Linux distributions, see [[cellular-infrastructure:Binary_Packages]] for more details. In case of doubt, use the nightly builds. |
101 | 1 | tsaitgaist | |
102 | 33 | laforge | h3. Installing binary packages |
103 | |||
104 | We assume that you've added the binary package feed, for example as described at [[cellular-infrastructure:Nightly_Builds]]. |
||
105 | |||
106 | All you need to do is to do |
||
107 | |||
108 | <pre> |

109 | $ sudo apt-get install simtrace2 |
||
110 | </pre> |
||
111 | |||
112 | |||
113 | h3. Building from source |
||
114 | |||

134 | </pre> |
||
135 | |||
136 | h3. Accessing it |
||
137 | |||
138 | Add udev rules so to be able to use SIMtrace 2 devices and access the device as non-root user: |
||
139 | <pre> |
||
140 | # add current user to plugdev group (user needs to re-login for this change to take effect) |
||
141 | sudo adduser $USERNAME plugdev |
||
142 | # grant access permission to SIMtrace 2 for plugdev group |
||
143 | 29 | roh | sudo wget -O /etc/udev/rules.d/99-simtrace2.rules https://git.osmocom.org/simtrace2/plain/host/contrib/99-simtrace2.rules |
144 | 13 | tsaitgaist | # reload udev rules |

147 | </pre> |
||
148 | |||
149 | h3. Applications |
||
150 | |||
151 | h4. simtrace2-list |
||
152 | |||

||
154 | <pre> |
||
155 | ./simtrace2-list |
||
156 | USB matches: 1 |
||
157 | 1d50:60e3 Addr=4, Path=2-2.3, Cfg=1, Intf=0, Alt=0: 255/1/0 (SIMtrace Sniffer) |
||
158 | </pre> |
||
159 | |||
160 | This is useful when you have multiple devices (such as with the [[Wiki#sysmoQMOD]]) and have to specific with device to use by the other applications. |
||
161 | |||
162 | h4. simtrace2-sniff |
||
163 | |||
164 | This will use the [[Wiki#trace|trace]] firmware and retrieve the sniffed phone-SIM communication. |
||
165 | The activity will be shown on the consol output: |
||
166 | <pre> |
||
167 | ./simtrace2-sniff |
