Question 50
A stolen bearer token is used to act as an authenticated user without knowledge of the password. Which attack pattern fits?
- Exfiltration over HTTPS
- Session hijacking
- Port scanning
- Lateral movement
Explanation
Correct Answer
B:Session hijacking abuses an existing session credential or token. Token lifetime, binding, issuance and observed reuse are relevant; a successful password login is not required.
Incorrect Answers
A:A case involving possible theft of data through encrypted outbound traffic might use this approach: exfiltration involves unauthorized removal of data; TLS can obscure content while timing, byte counts and endpoint history remain informative; the required result here is unauthorized reuse of an established authenticated session. Large transfers require corroboration before attribution; it cannot replace proof about unauthorized reuse of an established authenticated session.
C:Although the case asks about unauthorized reuse of an established authenticated session, port scanning tests service availability across ports, often using distinctive connection distributions; the action instead concerns rapid probing of many service ports. It does not by itself establish successful exploitation; it does not establish unauthorized reuse of an established authenticated session.
D:For an analysis centered on movement from one compromised host to another, lateral movement extends attacker reach from an initial foothold to additional hosts or accounts; the present need is unauthorized reuse of an established authenticated session. Authentication and remote-execution evidence helps establish the path; a different finding about unauthorized reuse of an established authenticated session is still needed.
Question 51
A customer's telephone number is reassigned at the carrier, followed by authentication messages reaching an attacker-owned SIM. Which fraud mechanism fits?
- IoT telemetry manipulation
- SIM swapping
- Default IoT credentials
- Botnet enrollment
Explanation
Correct Answer
B:SIM swapping redirects control of a cellular subscription, often to intercept SMS authentication and recover accounts. Carrier provisioning records are central evidence.
Incorrect Answers
A:Even though the scenario needs fraudulent transfer of control over a phone number, telemetry manipulation compromises the trustworthiness of sensor output without necessarily interrupting connectivity; the action relates to falsification of device measurement data. Investigators compare calibration, firmware and independent physical readings; this remains insufficient for fraudulent transfer of control over a phone number.
C:The objective here is fraudulent transfer of control over a phone number; default credentials provide a predictable authentication route when not changed; the option would instead inform factory account secrets enabling unauthorized access. Login artifacts and device access controls should be preserved before configuration remediation; it is not direct evidence of fraudulent transfer of control over a phone number.
D:For a separate investigation of compromised devices acting in coordinated attacks, botnet enrollment turns compromised devices into remotely controlled participants; that is not the determination of fraudulent transfer of control over a phone number in the stem. Correlated commands and outbound patterns distinguish shared infection from independent failures; the evidence still must speak to fraudulent transfer of control over a phone number.
Question 52
An Android handset has an APK installed from outside the normal managed app channel. Which installation pathway is under scrutiny?
- Default IoT credentials
- Mobile application sideloading
- Malicious mobile overlay
- SIM swapping
Explanation
Correct Answer
B:Sideloading installs application packages through alternate distribution methods. The package source and signing information matter; sideloading alone does not prove maliciousness.
Incorrect Answers
A:Instead of a method addressing an app installed outside the approved distribution channel, default credentials provide a predictable authentication route when not changed; this one concerns factory account secrets enabling unauthorized access. Login artifacts and device access controls should be preserved before configuration remediation; it cannot independently determine an app installed outside the approved distribution channel.
C:A case involving deceptive UI covering a legitimate application might use this approach: overlay abuse uses drawing or accessibility capabilities to mimic sensitive screens and intercept interaction; the required result here is an app installed outside the approved distribution channel. The attacker targets user input rather than SIM provisioning; it cannot replace proof about an app installed outside the approved distribution channel.
D:The required finding is about an app installed outside the approved distribution channel; SIM swapping redirects control of a cellular subscription, often to intercept SMS authentication and recover accounts; this addresses the separate concern of fraudulent transfer of control over a phone number. Carrier provisioning records are central evidence; it does not by itself answer an app installed outside the approved distribution channel.
Question 53
A mobile device shows privileged modifications that bypass platform restrictions and expose normally protected areas. Which condition is suggested?
- Botnet enrollment
- Bluetooth attack surface
- Jailbreak/root compromise
- Malicious mobile overlay
Explanation
Correct Answer
C:Rooting or jailbreaking changes device privilege boundaries and can weaken app isolation. Confirming the modification requires platform-specific evidence rather than one suspicious file name.
Incorrect Answers
A:The current inquiry asks about bypassed mobile operating-system privilege restrictions; botnet enrollment turns compromised devices into remotely controlled participants; this mechanism chiefly addresses compromised devices acting in coordinated attacks. Correlated commands and outbound patterns distinguish shared infection from independent failures; it cannot prove bypassed mobile operating-system privilege restrictions on its own.
B:In an inquiry concerning nearby peer connectivity through Bluetooth, bluetooth radio pairing and service exposure create a separate local attack surface; the scope does not extend to bypassed mobile operating-system privilege restrictions. Logs and captures may be limited, so device settings and peer history matter; that issue cannot settle bypassed mobile operating-system privilege restrictions.
D:For the separate question of deceptive UI covering a legitimate application, overlay abuse uses drawing or accessibility capabilities to mimic sensitive screens and intercept interaction; the requested assessment of bypassed mobile operating-system privilege restrictions remains open. The attacker targets user input rather than SIM provisioning; there is no direct finding about bypassed mobile operating-system privilege restrictions.
Question 54
An unfamiliar application places a fake login window over a banking app and captures entered credentials. Which mobile threat behavior is this?
- Malicious mobile overlay
- Botnet enrollment
- Default IoT credentials
- Jailbreak/root compromise
Explanation
Correct Answer
A:Overlay abuse uses drawing or accessibility capabilities to mimic sensitive screens and intercept interaction. The attacker targets user input rather than SIM provisioning.
Incorrect Answers
B:The stem asks about deceptive UI covering a legitimate application; botnet enrollment turns compromised devices into remotely controlled participants; the described operation is used for compromised devices acting in coordinated attacks. Correlated commands and outbound patterns distinguish shared infection from independent failures; a determination about deceptive UI covering a legitimate application requires other support.
C:Instead of a method addressing deceptive UI covering a legitimate application, default credentials provide a predictable authentication route when not changed; this one concerns factory account secrets enabling unauthorized access. Login artifacts and device access controls should be preserved before configuration remediation; it cannot independently determine deceptive UI covering a legitimate application.
D:In work concerning bypassed mobile operating-system privilege restrictions, rooting or jailbreaking changes device privilege boundaries and can weaken app isolation; the operation would not resolve deceptive UI covering a legitimate application. Confirming the modification requires platform-specific evidence rather than one suspicious file name; the distinction leaves deceptive UI covering a legitimate application unsettled.
Question 55
An unauthorized app persistently collects location and messages and sends them to a third party. Which class of unwanted software is likely?
- Mobile stalkerware
- Jailbreak/root compromise
- Mobile application sideloading
- IoT telemetry manipulation
Explanation
Correct Answer
A:Stalkerware covertly monitors personal activity and transmits it to an operator. Permissions, persistence, and outbound endpoints require careful contextual assessment.
Incorrect Answers
B:When the investigative task is bypassed mobile operating-system privilege restrictions, rooting or jailbreaking changes device privilege boundaries and can weaken app isolation; that differs from the question about covert surveillance of device owner activity. Confirming the modification requires platform-specific evidence rather than one suspicious file name; that leaves covert surveillance of device owner activity unresolved.
C:The current inquiry asks about covert surveillance of device owner activity; sideloading installs application packages through alternate distribution methods; this mechanism chiefly addresses an app installed outside the approved distribution channel. The package source and signing information matter; sideloading alone does not prove maliciousness; it cannot prove covert surveillance of device owner activity on its own.
D:In an inquiry concerning falsification of device measurement data, telemetry manipulation compromises the trustworthiness of sensor output without necessarily interrupting connectivity; the scope does not extend to covert surveillance of device owner activity. Investigators compare calibration, firmware and independent physical readings; that issue cannot settle covert surveillance of device owner activity.
Question 56
A network camera starts operating with altered boot code and undocumented external connections. What compromise area should investigators prioritize?
- SIM swapping
- Jailbreak/root compromise
- Mobile application sideloading
- Rogue IoT firmware
Explanation
Correct Answer
D:Firmware tampering changes low-level device software and may survive application-level resets. Validated images, signatures and boot records can reveal unauthorized modifications.
Incorrect Answers
A:For a separate investigation of fraudulent transfer of control over a phone number, SIM swapping redirects control of a cellular subscription, often to intercept SMS authentication and recover accounts; that is not the determination of unauthorized alteration of embedded device firmware in the stem. Carrier provisioning records are central evidence; the evidence still must speak to unauthorized alteration of embedded device firmware.
B:With unauthorized alteration of embedded device firmware as the investigative issue, rooting or jailbreaking changes device privilege boundaries and can weaken app isolation; the result would concern bypassed mobile operating-system privilege restrictions. Confirming the modification requires platform-specific evidence rather than one suspicious file name; this would not resolve unauthorized alteration of embedded device firmware.
C:For questions about an app installed outside the approved distribution channel, sideloading installs application packages through alternate distribution methods; that differs from unauthorized alteration of embedded device firmware. The package source and signing information matter; sideloading alone does not prove maliciousness; it provides no direct answer to unauthorized alteration of embedded device firmware.
