A device may receive an instruction to automatically install a program using a click area prediction model. The click area prediction model may be associated with predicting a click area of a user interface that, when selected, causes a program installation procedure to proceed. The device may identify an installation user interface associated with installing the program. The device may determine a group of regions included in the installation user interface. The device may identify sets of features associated with the group of regions. The device may determine, based on the sets of features and the click area prediction model, a group of scores associated with the group of regions. The device may identify a particular region as a predicted click area based on the group of scores. The device may select the predicted click area to attempt to cause the program installation procedure to proceed.

A device may receive or generate a message for routing to a destination on a communication channel. The communication channel may have been established between a source and the destination. The device may perform a first determination of policy information related to at least one of the message, the destination, or the source of the message. The policy information may describe an action for a network device to perform. The device may associate a policy token with the message. The policy token may describe or identify the policy information. The device may provide the message with the associated policy token to the network device on the communication channel to cause the network device to perform a second determination of the policy information based on the policy token, to perform the action described by the policy information, and to provide the message on the communication channel.

A device may detect or emulate a sequence of keystrokes to be used to detect a keystroke logger application. The device may determine a sequence of characters associated with the sequence of keystrokes. The sequence of characters may correspond to the sequence of keystrokes or a portion of the sequence of keystrokes. The device may search a memory for the sequence of characters. The device may determine that the sequence of characters is stored in the memory based on searching the memory for the sequence of characters. The device may perform an action to counteract the keystroke logger application based on determining that the sequence of characters is stored in the memory.

A security device may receive a request from a client device and intended for a server device. The security device may identify the request as being associated with a malicious activity. The malicious activity may include one or more undesirable tasks directed to the server device. The security device may generate a challenge-response test based on identifying the request as being associated with the malicious activity. The challenge-response test may be generated using one or more construction techniques. The security device may provide the challenge-response test to the client device. The security device may receive, from the client device, a proposed solution to the challenge-response test. The security device may identify the proposed solution as being generated using an optical character recognition (OCR) program. The security device may protect the server device from the client device based on identifying the solution as being generated using an OCR program.

A device may detect an attack. The device may receive, from a client device, a request for a resource. The device may determine, based on detecting the attack, a computationally expensive problem to be provided to the client device, where the computationally expensive problem requires a computation by the client device to solve the computationally expensive problem. The device may instruct the client device to provide a solution to the computationally expensive problem. The device may receive, from the client device, the solution to the computationally expensive problem. The device may selectively provide the client device with access to the resource based on the solution.

A device may receive a trigger to determine whether one or more client devices, of a set of client devices, are infected by a malicious file. The device may generate file identification information associated with the malicious file based on receiving the trigger to determine whether the one or more client devices are infected by the malicious file. The device may obtain remote access to the one or more client devices using a connection tool based on receiving the trigger to determine whether the one or more client devices are infected by the malicious file. The device may obtain information, associated with the one or more client devices, using the remote access. The device may provide information indicating whether the one or more client devices are infected by the malicious file based on the file identification information and the information associated with the one or more client devices.

A device may receive a password-protected file to be accessed for analysis. The device may identify a contextual term, associated with the password-protected file, to be used as a password to attempt to access the password-protected file. The contextual term may be identified based on at least one of: metadata associated with the password-protected file, metadata associated with a source from which the password-protected file is received, or text associated with the source from which the password-protected file is received. The device may apply the contextual term as the password to attempt to access the password-protected file.
摘要:
This disclosure describes techniques for proactively identifying possible attackers based on a profile of a device. For example, a device includes one or more processors and network interface cards to receive, from a remote device, network traffic directed to one or more computing devices protected by the device, determine, based on content of the network traffic, a first set of data points for the device, send a response to the remote device to ascertain a second set of data points for the device, and receive, from the remote device, at least a portion of the second set of data points. The device also includes a security module operable by the processors to determine a maliciousness rating, and selectively manage, based on the maliciousness rating, additional network traffic directed to the one or more computing devices protected by the security device and received from the remote device.

A device may receive, from a first device, a first message that includes a first random cookie and a session cookie. The device may provide the first message to a second device. The device may receive, from the second device, a second message that includes a response to the first message. The device may generate a second random cookie. The second random cookie may be different from the first random cookie. The device may provide, to the first device, the second random cookie, the session cookie, and the response.
