A system and method for fast-detection and mitigation of emerging network fraud attacks includes sourcing digital event data samples associated with one or more online services; executing graph-rendering computer instructions that automatically construct a backbone graph using a subset of features extracted from the sourced digital event data samples, wherein the constructing includes: identifying, as graphical nodes, a first plurality of distinct features of the subset of features; identifying, as graphical edges, a second plurality of distinct features of the subset of features; generating a graphical edge between distinct pairs of graphical nodes comprising a same type of feature of the subset of features based on feature values associated with at least one distinct feature of the second plurality of distinct features; and mitigating, via a digital threat mitigation action, if one or more emerging network fraud attacks is identified based on an assessment of a cluster of networked nodes.

The disclosure is directed to providing content access control in information centric networking (ICN) networks. Methods and systems include hardware and/or software that perform operations for sending to a content provider of an ICN network an access request for content in response to receiving a first content request from a client. The operations also include receiving from the content provider access control information for the content. The operations further include sending to the client a challenge. Additionally, the operations include receiving from the client an authorization of the content provider that includes information obtained by the client from the content provider based on the challenge. Furthermore, the operations include verifying the authorization received from the client using the access control information received from the content provider. Moreover, the operations include sending to the client the content.

A financial institution computing system associated with a financial institution includes a network interface configured to communicate data over a network, and a processing circuit comprising a memory and a processor. The memory has instructions stored thereon that cause the processor to receive, by the network interface, a content request from a user computing device associated with a user, the content request requesting content from a network destination, determine if the network destination is associated with a trusted entity, determine that the requested content prompts the user to input sensitive information, and transmit, by the network interface substitution content to the user computing device responsive to determining that the network destination is illegitimate and to determining that the requested content includes at least one field into which the user may input sensitive information, the substitution content including at least one prompt requesting the user to input sensitive information.

An endpoint protection system is provided. The system comprises: an endpoint agent deployed to an endpoint device, wherein the endpoint agent is built-into one or more existing applications running on the endpoint device and is configured to capture network session activity between the endpoint device and one or more internet servers to detect a phishing attack using a set of machine learning algorithm trained classifiers, and block the phishing attack; and an endpoint management system in remote communication with the endpoint agent, wherein the endpoint management system is configured to train and develop the set of classifiers, and receive information about the detected phishing attack and an incident report from the endpoint agent, the endpoint agent provides a graphical user interface running on the endpoint device allowing an end user to configure one or more protections provided by the endpoint agent.

The disclosed computer-implemented method for protecting against misleading clicks on websites may include (i) detecting a user click event on a uniform resource locator (URL) for navigating to a website during a web browsing session, (ii) analyzing the user click event to identify expected domain behavior associated with navigating to the website based on the URL, (iii) determining, based on the analysis, that the user click event deviates from the expected domain behavior associated with navigating to the website based on the URL, and (iv) performing a security action that protects against potentially malicious activity caused by the user click event deviating from the expected domain behavior associated with navigating to the website based on the URL. Various other methods, systems, and computer-readable media are also disclosed.

At least one of a measure of trust or a measure of spoofing risk associated with a sender of a message is determined. A measure of similarity between an identifier of the sender of the message and an identifier of at least one trusted contact of a recipient of the message is determined. The measure of similarity is combined with at least one of the measure of trust or the measure of spoofing risk to at least in part determine a combined measure of risk associated with the message. Based at least in part on the combined measure of risk associated with the message, a verification action is performed including by automatically providing an inquiry message that requests a response to be provided.

Apparatus, systems and methods for agile network isolation through use of packet level non-repudiation (PLNR) are provided. Using a fast cryptography to verify that incoming packets are undeniably being received from the identified source, real-time attack notifications can be independently verified and shared among the network devices to remove compromised nodes from the network. The ability to collaborate among nodes without trust may be achieved via PLNR, to share attack notifications in real-time may be achieved via Telling Attack Layer (TATL), and to establish the identity of an attack in a permanent and binding way may be achieved via DISCOvery (DISCO).

A proxy server receives from a client device a request for a network resource that is hosted at an origin server for a domain. The request is received at the proxy server as a result of a DNS request for the domain resolving to the proxy server. The origin server is one of multiple origin servers that belong to different domains that resolve to the proxy server and are owned by different entities. The proxy server retrieves the requested network resource. The proxy server determines that the requested resource is an HTML page. The proxy server scans the HTML page to locate one or more modification tokens that each indicates content that is subject to being modified. For at least one of the located modification tokens, the proxy server automatically modifies at least a portion of the content of the HTML page that corresponds to that modification token. The proxy server then transmits the modified HTML page to the client device.

A method for applying policies to an email message includes receiving, by an inbound policy module in a protected network, message metadata of an email message. The method also includes determining, based on the message metadata, whether receiving the email message in the protected network is prohibited by at least one metadata policy. The method further includes blocking the email message from being forwarded to the protected network if receiving the email message in the protected network is prohibited by the metadata policy. In specific embodiments, the method includes requesting scan results data for the email message if receiving the email message in the protected network is not prohibited by one or more metadata policies. In further embodiments, the method includes receiving the scan results data and requesting the email message if receiving the email message in the protected network is not prohibited by one or more scan policies.
