CAPEC-508: Shoulder Surfing

Attack Pattern ID: 508
Abstraction: Detailed
Status: Draft
Presentation Filter:
+ Description
In a shoulder surfing attack, an adversary observes an unaware individual's keystrokes, screen content, or conversations with the goal of obtaining sensitive information. One motive for this attack is to obtain sensitive information about the target for financial, personal, political, or other gains. From an insider threat perspective, an additional motive could be to obtain system/application credentials or cryptographic keys. Shoulder surfing attacks are accomplished by observing the content "over the victim's shoulder", as implied by the name of this attack.

The table below shows the other attack patterns and high level categories that are related to this attack pattern. These relationships are defined as ChildOf and ParentOf, and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as CanFollow, PeerOf, and CanAlsoBe are defined to show similar attack patterns that the user may want to explore.

NatureTypeIDName
ChildOfStandard Attack PatternStandard Attack Pattern - A standard level attack pattern in CAPEC is focused on a specific methodology or technique used in an attack. It is often seen as a singular piece of a fully executed attack. A standard attack pattern is meant to provide sufficient details to understand the specific technique and how it attempts to accomplish a desired goal. A standard level attack pattern is a specific type of a more abstract meta level attack pattern.651Eavesdropping
CanPrecedeMeta Attack PatternMeta Attack Pattern - A meta level attack pattern in CAPEC is a decidedly abstract characterization of a specific methodology or technique used in an attack. A meta attack pattern is often void of a specific technology or implementation and is meant to provide an understanding of a high level approach. A meta level attack pattern is a generalization of related group of standard level attack patterns. Meta level attack patterns are particularly useful for architecture and design level threat modeling exercises.560Use of Known Domain Credentials

The table below shows the views that this attack pattern belongs to and top level categories within that view.

+ Prerequisites
The adversary typically requires physical proximity to the target's environment, in order to observe their screen or conversation. This may not be the case if the adversary is able to record the target and obtain sensitive information upon review of the recording.
+ Skills Required
[Level: Low]
In most cases, an adversary can simply observe and retain the desired information.
+ Consequences

The table below specifies different individual consequences associated with the attack pattern. The Scope identifies the security property that is violated, while the Impact describes the negative technical impact that arises if an adversary succeeds in their attack. The Likelihood provides information about how likely the specific consequence is expected to be seen relative to the other consequences in the list. For example, there may be high likelihood that a pattern will be used to achieve a certain impact, but a low likelihood that it will be exploited to achieve a different impact.

+ Mitigations
Be mindful of your surroundings when discussing or viewing sensitive information in public areas.
Pertaining to insider threats, ensure that sensitive information is not displayed to nor discussed around individuals without need-to-know access to said information.
+ Example Instances
An adversary can capture a target's banking credentials and transfer money to adversary-controlled accounts.
An adversary observes the target's mobile device lock screen pattern/passcode and then steals the device, which can now be unlocked.
An insider could obtain database credentials for an application and sell the credentials on the black market.
An insider overhears a conversation pertaining to classified information, which could then be posted on an anonymous online forum.
