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: |

Telegram has gained a reputation as the “secure” communications app in the post-Soviet states, but whenever you make choices about your digital security, it’s important to start by asking yourself, “What exactly am I securing? And who am I securing it from?” These questions should inform your decisions about whether you are using the right tool or platform for your digital security needs. Telegram is certainly not the most secure messaging app on the market right now. Its security model requires users to place a great deal of trust in Telegram’s ability to protect user data. For some users, this may be good enough for now. For others, it may be wiser to move to a different platform for certain kinds of high-risk communications. As such, the SC would like to remind investors to always exercise caution when evaluating investment opportunities, especially those promising unrealistically high returns with little or no risk. Investors should also never deposit money into someone’s personal bank account if instructed. On December 23rd, 2020, Pavel Durov posted to his channel that the company would need to start generating revenue. In early 2021, he added that any advertising on the platform would not use user data for targeting, and that it would be focused on “large one-to-many channels.” He pledged that ads would be “non-intrusive” and that most users would simply not notice any change. Individual messages can be fully encrypted. But the user has to turn on that function. It's not automatic, as it is on Signal and WhatsApp. In December 2021, Sebi officials had conducted a search and seizure operation at the premises of certain persons carrying out similar manipulative activities through Telegram channels.
