Abstract: Among other things, we describe techniques for encoding data that is included in electronic communications. In one aspect, a first electronic communication system sends, to an entity, a first email message that includes a Message-ID field including data that identifies an action to be carried out by a second electronic communication system. The first electronic communication system receives, from the entity, a second email message that includes an In-Reply-To field containing the data that identifies the action to be carried out by the second electronic communication system. The first electronic communication extracts the data from the In-Reply-To field in a message header of the first electronic communication. The second electronic communication system may be the same as the first electronic communication system, or may be an electronic communication system other than the first electronic communication system.

Abstract: The invention is related to security systems and methods for proactively informing a user about an artifact associated with a clickable object on a user interface with which the user is interacting, where such information is provided to the user prior to selection of the clickable object. The information includes a safety assessment of the clickable object, details about the underlying artifact, such as the contents of an archive file, and general information helpful in assisting the user with making a decision as to whether to select the clickable object.

Abstract: The present disclosure relates generally to the field of data processing and electronic messaging systems, and, more particularly, to systems and methods for mediating a user's access to a resource to thereby prevent potential security breaches, including phishing and impersonation, malware, and security issues, particularly with respect to websites and electronic communications.

Abstract: Today's user is facing an ever increasing number of cyber threats from infectious software to scam artist phishing for their passwords and other personal information. Accordingly, a technique is provided to mediate a user's access to electronic resources, which can include malware and sites that trick the user into giving their password. Based on information known about the resource at the time the user accesses it, the technique can warn the user that the resources is suspicious and it is not safe to provide their password. Even if the resource is safe, the technique can warn the user not reuse their password, thereby promoting good password hygiene.

Abstract: Virtually every online account requires login credentials like username and password for access. Using different credentials for each account can reduce the likelihood of unauthorized access to these accounts. Remembering all the different credentials, however, can be a challenge and it is not uncommon for a user to mistakenly provide credentials to a site that are for another, sensitive site. Accordingly, a system for warning a user of such an error is provided. The system includes a browser plugin that responds to a user entering their credentials at a requesting site by looking up an identifier of a trusted site associated with the user's credentials. The identifiers of the requesting and trusted sites are compared, and if they do not match, the browser plugin blocks the user from submitting their credentials to the requesting site. Advantageously, the system reduces the likelihood that credentials to sensitive accounts are provided by accident.

Abstract: The invention is a security system providing domain name authentication for intrusion and malware prevention. The system is configured to analyze domain names, specifically analyze network metadata associated with said domain names, and further identify domain names attempting to impersonate or spoof domain names associated with a trusted entity or party.
