An iPhone client's most noticeably terrible bad dream is to have somebody oversee his/her gadget, including the capacity to record and control all action without waiting be in a similar room. In this blog entry, we present another weakness called "Trustjacking", which permits an aggressor to do precisely that.
This weakness misuses an iOS highlight called iTunes Wi-Fi sync, which permits a client to deal with their iOS gadget without genuinely interfacing it to their PC. A solitary tap by the iOS gadget proprietor when the two are associated with a similar organization permits an assailant to oversee the gadget. Furthermore, we will stroll through past related weaknesses and show the progressions that iPhone has made to alleviate them, and why these are adequately not to forestall comparative assaults.
After interfacing an iOS gadget to another PC, the clients are being found out if they trust the associated PC or not. Deciding to believe the PC permits it to speak with the iOS gadget by means of the standard iTunes APIs.
This permits the PC to get to the photographs on the gadget, perform reinforcement, introduce applications and considerably more, without requiring another affirmation from the client and with no recognizable sign.
Besides, this permits enacting the "iTunes Wi-Fi sync" highlight, which makes it conceivable to proceed with this sort of correspondence with the gadget even after it has been detached from the PC, as long as the PC and the iOS gadget are associated with a similar organization. It is intriguing to take note of that empowering
"iTunes Wi-Fi sync" doesn't need the casualty's endorsement and can be directed simply from the PC side.
Getting a live stream of the gadget's screen should be possible effectively by consistently requesting screen captures and showing or recording them distantly.
It is imperative to take note of that other than the underlying single purpose of disappointment, approving the vindictive PC, there is no other component that forestalls this proceeded with access. Likewise, there isn't anything that informs the clients that by approving the PC they permit admittance to their gadget even in the wake of detaching the USB link.

While perimeter defenses like firewalls and IPS provide a layer of protection, internal systems (such as network elements) must also be hardened. This includes:
Enforcing strong authentication
Applying regular patches and updates
Conducting vulnerability assessments and security audits
Security should be layered (defense in depth), and reliance on perimeter defense alone is insufficient.

Quote:
"Internal systems must be hardened with secure configurations and tested regularly. A layered security approach is required even in protected environments." Incorrect Options:
B & C. Relying only on perimeter or physical security is not sufficient D). While backup sites are part of DR, they don't replace proactive protection

Challenge/response authentication is designed to prevent replay attacks. In this mechanism:
* The server sends a random "challenge" string.
* The client uses its secret (like a password or private key) to generate a response.
* The server verifies that the response matches what it expected for that challenge.
Since the challenge is random and changes each time, an attacker cannot simply capture and replay previous responses to gain unauthorized access.
From CEH v13 Courseware:
* Module 11: Session Hijacking
* Module 6: Authentication Protocols
CEH v13 Study Guide states:
"Challenge-response authentication prevents replay attacks by using dynamically generated nonces or challenge tokens that change with each session." Incorrect Options:
* B: Scanning attacks are not related to authentication mechanisms.
* C: Session hijacking involves active takeovers, not replaying login attempts.
* D: Password cracking targets password hashes, not session tokens.

This Social Engineering scam involves an exchange of information that can benefit both the victim and the trickster. Scammers would make the prey believe that a fair exchange will be present between both sides, but in reality, only the fraudster stands to benefit, leaving the victim hanging on to nothing. An example of a Quid Pro Quo is a scammer pretending to be an IT support technician. The con artist asks for the login credentials of the company's computer saying that the company is going to receive technical support in return. Once the victim has provided the credentials, the scammer now has control over the company's computer and may possibly load malware or steal personal information that can be a motive to commit identity theft.
"A quid pro quo attack (aka something for something" attack) is a variant of baiting. Instead of baiting a target with the promise of a good, a quid pro quo attack promises a service or a benefit based on the execution of a specific action." https://resources.infosecinstitute.com/topic/common-social-engineering-attacks/#:~:

According to CEH v13 Module 06: Malware Threats, when analyzing suspicious system behavior or investigating a suspected Trojan infection, a common and effective approach is to:
Monitor system activity and network behavior using tools like netstat, Wireshark, and TCPView.
Trojans often create covert channels or backdoors for remote access, which can be identified through unexpected or unauthorized outgoing connections to remote IP addresses or domains.
Using netstat -an or netstat -ano helps identify open ports and active connections, and checking these against known IPs can indicate whether a Trojan is communicating with a Command and Control (C&C) server.
Analysis of Each Option:
A). Use ExifTool and check for malicious content
Incorrect. ExifTool is primarily used for extracting metadata from files, especially images and documents. It is not effective for analyzing executable malware or system behavior post-execution.
B). You do not check; rather, you immediately restore a previous snapshot of the operating system Incorrect. While restoring from a snapshot might eventually be required, immediate restoration without diagnosis is not a recommended or forensically sound first step. It also prevents root cause analysis.
C). Upload the file to VirusTotal
Partially correct but not sufficient. While uploading the file to VirusTotal is a good step to confirm if the file is known malware, it does not identify whether the machine is currently infected or actively compromised.
D). Use netstat and check for outgoing connections to strange IP addresses or domains Correct. This method helps detect if the system is making suspicious external connections that are common in Trojan infections.
