Паранойя ё омодагӣ? Ҷосусҳо дар мизи шумо

Ман одатан саволҳо мегирам, ки чаро ман ба сенсорҳои равшании муҳити атрофи ноутбук ва телефони ман стикер насб кардаам. Баъзеҳо фикр мекунанд, ки ман фарқият байни сенсори равшанӣ ва камераро намедонам ва кӯшиш мекунанд ба ман фаҳмонанд, ки ин камера нест. Он чизе, ки онҳо намедонанд, ин аст, ки сенсорҳои рӯшноии атрофро метавон бо усулҳои омӯзиши мошинӣ истифода бурд, то маълумотҳоро ба таври камераҳои нотавон хориҷ кунанд.

Ман одатан аз мардум мешунавам: “Вале мо чизеро пинҳон надорем!” Хуб, Шумо бештар чизи пинҳон доред, аз он чизе ки фикр мекунед, Маълумоти шумо метавонад бо дигар маълумоте, ки аз шумо дар ҷойҳои дигар ҷамъ шудааст, якҷоя карда шуда, барои таҳияи иттилоот дар сатҳе истифода шавад, ки шумо ҳатто тасаввур карда наметавонед. Ва онҳо, ки маълумотро ҷамъ мекунанд, ҳатман бо ниятҳои дуруст нестанд. Маълумоти шумо метавонад аз ҷониби акторони таҳдидкунанда гуногун ҷамъоварӣ шуда, бо истифода аз AI таҳлил шуда, барои мақсадҳо ва ниятҳои гуногун истифода шавад.

Дар соҳаи киберхавфпазирӣ, мо гумон мекунем, ки агар як намуди ҳамла имконпазир бошад ва имконият барои анҷом додани ҳамла вуҷуд дошта бошад, пас шояд сабаби анҷом додани он ҳамлаҳо вуҷуд дошта бошад. We do not assume that those who can collect the data always have legitimate cause to collect that data. We also do not assume only a single party or entity exploit a vulnerability to collects that data.

Below is a list of other things that can be used to spy on you that you probably don’t know have such capabilities.

Your TV speaker can listen to you

I am one of those who usually choose a TV model without a microphone or camera before I need to physically remove those devices. I also have a home firewall and a secured internal network, but I have learned throughout the years not to only rely on logical controls. Аммо, based on a WikiLeaks release in 2017 ва documents from 2014, the CIA (in cooperation with MI5) turned speakers in certain TV models into microphones to collect data. They even developed a fake off mode to show that the TV is off when they collect those conversations. If you think your TV might listen to your conversation, it is better to unplug it when not in use. It also saves you some energy because plugged devices even while not in use may consume some electricity.

Your tablet or laptop light sensor can capture your hand or your image

I always adjust screen light manually, and I believe I have a good reason for that.

The ambient light sensor is used to measure the amount of light and to adjust the brightness of the screen. Ambient light sensors can be used to capture images or keystrokes to steal passwords and data. A group of MIT researchers recently created a proof of concept by using an Android tablet’s hand gestures captured by the ambient light sensor to capture touch interactions.

Your mouse may listen to your conversation

This one is outrageous! A mouse doesn’t have a microphone or even a speaker to be turned into a microphone to listen to anything. Аммо, there is a side channel attack known as “Mic-E-Mouse” that enables an attacker to listen to your conversations through your mouse.

A high performance gaming mouse (high DPI) can be hijacked by its optical sensor, so when you talk, voice vibrations can be measured with these sensors. Using machine learning algorithms and data from mouse sensors, security researchers can identify intelligible speech from vibrations.

Side channel attacks are a type of physical attack that measures changes in device output while a device performs an action. This type of attack is usually more sophisticated and targets certain assets like encryption keys. Аммо, if an attack method is developed for certain types of devices, it won’t be very difficult to expand it to other similar devices and even automate it.

Motion sensors (gyroscope) can be used to record your voice

Now that we learned your mouse can be used to record your talking, it’s good to know that motion sensors can also be used for the same purpose. This is important as almost all modern smart devices like phones and tablets have a gyroscope or motion sensor. The sensor acts as a vibrating device, making it perfect for side-channel attacks and to capture voice, as sound waves can produce tiny vibrations.

Your hard disk drive (HDD) noise can be captured to steal sensitive data

Now that we’ve learned about side channel attacks, there is a type of attack called DiskFiltration developed by a group of Israeli researchers that can capture sensitive data from the sound of a hard disk drive working. This type of attack is sophisticated and aims at devices with an air gap. With air gapped devices, a device is not connected to any network like the internet and is usually kept at sensitive facilities. Air gapped devices are not necessarily immune to cyber attacks. A classical example of these attacks is Stuxnet which targeted Iranian nuclear systems that were all air gapped.

Дар ин навъи ҳамла, ҳамлагар дастгоҳро бо нармафзоре сироят мекунад, ки тарзи коркарди дастгоҳро тағйир медиҳад. Нармафзор метавонад аз ҷониби ҳамлагар ворид карда шавад ё бо усулҳои дигар ба система дохил шавад. Дастгоҳ дорои фосилаи ҳаво мебошад, пас нармафзор ҳеҷ чизро ба берун интиқол дода наметавонад. Аммо, он дастгоҳро ба таври муайян кор мекунад, то ки дастгоҳи диск дар намунаҳои муайян ҳаракат кунад. Телефони наздик ё дастгоҳи дигар, ки фосилаи ҳаво надорад, метавонад барои сабт кардани садои диски сахт истифода шавад ва онро баргардонида ба маълумот табдил дод, ҳангоми навиштан ё хондани диск фосилаи ҳаво effectively нест карда мешавад.

Вентилятори компютери шумо метавонад маълумоти шуморо маҳрум кунад

Шумо дар системаи худ SSD доред ва аз HDD арзон ва садодор истифода намебаред. Пас агар дастгоҳи шумо дорои фосилаи ҳаво бошад, маълумоти ҳассос наметавонад хориҷ карда шавад. Хуб! Another group of Israeli researchers invented a method for you. Although your SSD doesn’t have an arm to rotate to make noise like with an HDD, your computer fan can be used to capture sound to compromise sensitive data from your air gapped computer. Дар ин навъи ҳамла, malware first infects the air gapped system (perhaps by an intruder to a secured facility), then the speed of the cooling fan will be changed in certain patterns. The sound can transmit the data to a nearby listening device.

WiFi signals can see through your walls

WiFi signals bounce off humans in a room. Researchers can see through walls to know how many people are in the room and identify individuals by movement and posture without needing any camera.
