Systems and methods for phishing attack protection based on identity provider verification
A computer system is provided. The computer system includes a memory and at least one processor coupled to the memory and configured to provide phishing attack protection based on identity provider verification. The at least one processor is further configured to capture an image of a browser web page to which the user has navigated and identify the domain name associated with the browser web page. The at least one processor is further configured to determine that the captured image matches an image of a known identity provider web page. The at least one processor is further configured to detect a phishing attempt in response to the determination that the images match and that the domain name associated with the browser web page differs from the domain name associated with the identity provider web page.
1. A computer system comprising:
a memory; and
at least one processor coupled to the memory and configured to:
train a neural network, the training including:
navigating to an identity provider (IdP) web page based on a domain name associated with the IdP web page;
capturing an image of the IdP web page;
generating variations of the image of the IdP web page by modifying attributes of the image of the IdP, the attributes including one or more of a background color, logos, fonts, dimensions, languages, words, or phrases; and
employing the variations to train the neural network;
capture an image of a browser web page;
identify a domain name associated with the browser web page;
employ the neural network to determine an image match where the captured image matches the image of the IdP web page; and
detect a phishing attempt in response to the determination of the image match, if the domain name associated with the browser web page differs from the domain name associated with the IdP web page.
2. The computer system of claim 1 , wherein the domain name associated with the IdP web page is obtained from a datastore of IdP web pages, the datastore configured by an administrator.
3. The computer system of claim 1 , wherein the at least one processor is further configured to bypass the detection of the phishing attempt in response to a determination that the browser web page is not a sign-in page.
4. The computer system of claim 1 , wherein the at least one processor is further configured to perform a security action in response to the detected phishing attempt, the security action including one or more of providing a warning to a device associated with a user who navigated to the browser web page, logging the detection, and generating an alert to an administrator.
5. A method for protection of user credentials comprising:
training, by a computer system, a neural network, the training including:
navigating to an identity provider (IdP) web page based on a second domain name associated with the IdP web page;
capturing an image of the IdP web page;
generating variations of the image of the IdP web page by modifying attributes of the image of the IdP, the attributes including one or more of a background color, logos, fonts, dimensions, languages, words, or phrases; and
employing the variations to train the neural network;
capturing, by the computer system, an image of a browser web page;
identifying, by the computer system, a first domain name associated with the browser web page;
employing, by the computer system, the neural network to determine that the captured image matches an image of the IdP web page;
determining, by the computer system, that the first domain name differs from the second domain name; and
detecting, by the computer system, a phishing attempt in response to the determination that the captured image matches the image of the IdP web page and the determination that the first domain name differs from the second domain name.
6. The method of claim 5 , wherein the second domain name is obtained from a datastore of IdP web pages, the datastore configured by an administrator.
7. The method of claim 5 , further comprising bypassing the detection of the phishing attempt in response to a determination that the browser web page is not a sign-in page.
8. The method of claim 5 , further comprising performing a security action in response to the detected phishing attempt, the security action including one or more of providing a warning to a device associated with a user who navigated to the browser web page, logging the detection, and generating an alert to an administrator.
9. A non-transitory computer readable medium storing executable sequences of instructions to provide protection of user credentials, the sequences of instructions comprising instructions to:
train a neural network, the training including:
navigating to an identity provider (IdP) web page based on a domain name associated with the IdP web page;
capturing an image of the IdP web page;
generating variations of the image of the IdP web page by modifying attributes of the image of the IdP, the attributes including one or more of a background color, logos, fonts, dimensions, languages, words, or phrases; and
employing the variations to train the neural network;
capture an image of a browser web page;
identify a domain name associated with the browser web page;
employ the neural network to determine an image match where the captured image matches the image of the IdP web page; and
detect a phishing attempt in response to the determination of the image match, if the domain name associated with the browser web page differs from the domain name associated with the IdP web page.
10. The computer readable medium of claim 9 , wherein the domain name associated with the IdP web page is obtained from a datastore of IdP web pages, the datastore configured by an administrator.
11. The computer readable medium of claim 9 , wherein the sequences of instructions further include instructions to bypass the detection of the phishing attempt in response to a determination that the browser web page is not a sign-in page.
12. The computer readable medium of claim 9 , wherein the sequences of instructions further include instructions to perform a security action in response to the detected phishing attempt, the security action including one or more of providing a warning to a device associated with a user who navigated to the browser web page, logging the detection, and generating an alert to an administrator.
