Abstract: The present disclosure discloses a method and apparatus for generating a candidate reply message. A specific embodiment of the method comprises: acquiring a text message of a currently received conversation; determining whether a pre-established conversation template matching the text message exists; and generating, in response to determining a conversation template matching the text message existing, a candidate reply message on the basis of the conversation template. According to the method provided by embodiments of the present disclosure, when the text message of the currently received conversation matches the pre-established conversation template, the candidate reply message is automatically generated, and a user may click the candidate reply message for reply, so that the time for the user to edit a reply message is saved, a period for the user to communicate with others is reduced, and the communication efficiency is improved.

Abstract: An anti-cracking method and system for a cloud host, as well as a terminal device are provided according to the disclosure. The method includes: obtaining system logs of the cloud host; determining an IP which fails to log in the cloud host according to the system logs as a suspicious IP; tracking and determining the suspicious IP to be an attacker IP according to the number of times of consecutive login failure of the suspicious IP; and adding a first blocking rule to firewall settings of the cloud host; wherein the first blocking rule instructs to block a login operation of the attacker IP during a first preset blocking time. With the anti-cracking method for a cloud host of the disclosure, the brute-force cracking can be prevented proactively in a timely manner with only very few system resources occupied.
