Ресёрчи, которые мы заслужили

Был куплен китайский тепловизор (Xtherm II T2S+), который подключался к смартфону. С ним в целом было всё нормально, но иногда он глючил

it works okay, but the app is sometimes buggy, crashes when changing settings, and phones home for some reason


И тут понеслось

Сначала автор расковырял приложение на Android, потом добрался до so-шки и начал разбираться с ней в Гидре (https://github.com/NationalSecurityAgency/ghidra), а так же смотреть что ещё есть в этом направлении.

Результатом всех страданий было решено допиливать своё
TL;DR I gave up on trying to patch that Android app since I am not experienced with either Android nor Java. Mainly because I found ht301_hacklib where someone ported the findings of netman in InfiCam to get the v1 of the T2S+ working in a very minimal Python script. My v2 also worked but showed a very distorted image. So I got to work figuring out how to get this to a usable state, to hopefully later make a C/C++ library/application that would allow me to make a standalone thermal camera out of a Raspberry Pi or something like that. 


Была доработана изначально взятая библиотека ht301_hacklib (патч так и не приняли, поэтому все фиксы так и живут его форке)

Далее была разобрана железка и составлено описание "кишок": курсирующие по форумам слухи, что в новых версиях изымался FPGA, не подтвердились.

В конце всего это процесса автор ещё наваял фичу, что бы можно было напрямую брать "сырые" данные с сенсора, осуществлять калибровку данных и получать вменяемую картинку, а так же добавил возможностей для отладки железа

To demonstrate this technique, I decapped an AD9042 ADC that I had in a ceramic DIP package. A Raspberry Pi Pico and a MOSFET were used to modulate the power to the chip, with the control software issuing ON/OFF commands over serial. This produced very nice results, even with a very low integration time. 

It's not only useful for silicon die debugging; it can also highlight even minute heat sources on PCBs and anything else that can be modulated, including people.


This feature allows you to use the camera in a lock-in mode. This allows for very precise measurements of hotspots on anything that can be modulated in some way. Examples include silicon dies, circuit boards, people (lock in based on heart rate) and potentially many others.

Telegram | DID YOU KNOW?

Date: |

Two days after Russia invaded Ukraine, an account on the Telegram messaging platform posing as President Volodymyr Zelenskiy urged his armed forces to surrender. In view of this, the regulator has cautioned investors not to rely on such investment tips / advice received through social media platforms. It has also said investors should exercise utmost caution while taking investment decisions while dealing in the securities market. Multiple pro-Kremlin media figures circulated the post's false claims, including prominent Russian journalist Vladimir Soloviev and the state-controlled Russian outlet RT, according to the DFR Lab's report. So, uh, whenever I hear about Telegram, it’s always in relation to something bad. What gives? Right now the digital security needs of Russians and Ukrainians are very different, and they lead to very different caveats about how to mitigate the risks associated with using Telegram. For Ukrainians in Ukraine, whose physical safety is at risk because they are in a war zone, digital security is probably not their highest priority. They may value access to news and communication with their loved ones over making sure that all of their communications are encrypted in such a manner that they are indecipherable to Telegram, its employees, or governments with court orders.
