Abstract
The present disclosure relates to a method and a device for detecting web address hijacking. The method includes: obtaining a currently accessed web address and a target directed web address from a current web address access instruction; determining a secure directed web address from the currently accessed web address according to a history of web address access instructions; and determining whether the target directed web address is hijacked according to the secure directed web address.
Claims12
A method for detecting web address hijacking, comprising:
- obtaining a currently accessed web address and a target directed web address from a current web address access instruction;
- determining a secure directed web address from the currently accessed web address according to a history of web address access instructions;
- and
- determining whether the target directed web address is hijacked according to the secure directed web address,
- wherein determining the secure directed web address from the currently accessed web address according to the history of web address access instructions comprises:
- obtaining at least one historical web address access instruction corresponding to the currently accessed web address from the history of web address access instructions, wherein the historical web address access instruction comprises an access web address, whether including a direct, a directed web address, and an access time;
- and
- determining the secure directed web address from the currently accessed web address according to the at least one historical web address access instruction,
- wherein determining the secure directed web address from the currently accessed web address according to at least one historical web address access instruction comprises:
- performing a statistical analysis on the at least one historical web address access instruction, and computing an occurrence probability of each directed web address in the at least one historical web address access instruction independently;
- and
- determining the secure directed web address from the currently accessed web address according to the occurrence probability of each directed web address and/or the access time of each directed web address, and
- wherein determining the secure directed web address from the currently accessed web address according to the occurrence probability of each directed web address and/or the access time comprises:
- determining a directed web address as the secure directed web address, if an access interval from a last access time of the directed web address to a current access time is less than a preset time interval, and a number of continuous occurrences of the directed web address is greater than or equal to a preset number.

A device for detecting web address hijacking, comprising:
- a processor;
- and
- a memory configured to store instructions executable by the processor,
- wherein the processor is configured to:
- obtain a currently accessed web address and a target directed web address from a current web address access instruction;
- determine a secure directed web address from the currently accessed web address according to a history of web address access instructions;
- and
- determine whether the target directed web address is hijacked according to the secure directed web address,
- wherein the processor is further configured to:
- obtain at least one historical web address access instruction corresponding to the currently accessed web address from the history of web address access instructions, wherein the historical web address access instruction comprises an access web address, whether including a direct, a directed web address, and an access time;
- and
- determine the secure directed web address from the currently accessed web address according to the at least one historical web address access instruction, and
- wherein the processor is further configured to:
- perform a statistical analysis on the at least one historical web address access instruction, and compute an occurrence probability of each directed web address in the at least one historical web address access instruction independently;
- and
- determine the secure directed web address from the currently accessed web address according to the occurrence probability of each directed web address and/or the access time of each directed web address, and
- wherein the processor is further configured to:
- determine a directed web address as the secure directed web address, if an access interval from a last access time of the directed web address to a current access time is less than a preset time interval, and a number of continuous occurrences of the directed web address is greater than or equal to a preset number.
