Study Notes

Hardware Exploits and Mobile Security

This section covers cyber threats related to hardware, USB drives, remote takeover, and mobile security.
Cyber threats related to hardware are discussed.
USB drive-related threats and prevention methods are explored.
Remote takeover related threats are detailed.
Mobile security is also addressed.

Hardware Vulnerabilities and Mobile Security

Software and cyber space security issues were previously discussed.
This section focuses on hardware—physical devices and connections used for internet access, and how they can cause threats.

USB Drives

A USB flash drive is a data storage device using flash memory, which is electrically erasable and reprogrammable.
It features an integrated USB interface for easy computer connection.
Most drives weigh less than 30 grams and have up to 2 terabyte capacity.
Hackers can use USB drives to introduce malicious code onto target computers.
Infected USB drives can then infect any device to which they are plugged.
Malware such as backdoors, Trojans, and hijackers may be installed to redirect the user to malicious websites.
The Stuxnet attack on Iranian nuclear centrifuges is example of a malware infection transmitted through a USB drive.

USB Drive Protection Guidelines

Avoid sensitive personal data on USB drives; use encryption if necessary.
Download encryption programs from reliable websites.
Use fingerprint authentication or built-in encryption for more secure USB drives.
Use personal USB drives only.
Be cautious when inserting unknown USB drives to avoid introducing malicious code.
Keep home and office devices separate.
Avoid opening unknown files on your device.

Remote Takeover

Modern technology is increasingly connected to the internet.
Connected devices, like TVs, cameras, hard drives, and webcams, facilitate communication and data sharing.
These devices can also be vulnerable to hacking.
Hackers can remotely control devices and access data or systems through security flaws.
A significant number of internet-connected devices exist making it easier for hackers to target and exploit such devices.
Malicious software such as keyloggers can be used to record and monitor keystrokes.
The potential to hack into systems through default passwords and lack of security measures is very likely and often present in networked systems.
The use of strong passwords and security measures for all connected devices is critical to avoid remote takeovers.

Mobile Security

Smartphones function like computers with processors, RAM, and operating systems, storing significant data.
Steps to secure smartphones from infiltration can be applied to avoid sensitive information extraction if stolen.
Social media applications and location services can compromise device security if not appropriately protected.
Hackers may use fraudulent methods, such as spoofing calls, to obtain sensitive data.
Secure web connections are crucial, as are measures to avoid suspicious links and apps prior to installation.
Mobile security entails protecting smartphones from remote takeover and malware by utilizing security measures specific to mobile devices.
Using strong passwords, disabling unnecessary connections, and employing two-factor authentication are recommended.
Sensitive data should be protected by employing strong security protocols for secure data storage and use to mitigate the risks of infiltration.

Wearable Devices

Wearable technologies like smartwatches can also pose security risks.
Aggregated, public data from fitness tracking devices or other wearable technologies can be susceptible to malware or data theft.
Sensitive information or locations from these devices can be revealed.
Data privacy and security concerns remain with the use of such devices.
