Abstract: This disclosure describes techniques for preventing network attacks within messages. For instance, electronic device(s) may receive a message, such as an email, from a first electronic device. The message may include a first code with a first embedded address to a first network resource, such as a malicious network resource. As such, the electronic device(s) may analyze the message to identify the first code. The electronic device(s) may then generate a second address associated with a second network resource, such as a secure proxy, a remote browser, a click-time protection service, and/or the like. Next, the electronic device(s) may embed the second address in a second code and replace the first code within the message with the second code. After replacing the first code, the electronic device(s) may send the message to a second electronic device of the second user.
