Description
Technical Field
The invention relates to the technical field of mobile internet, in particular to a method and a device for generating mirror image software and a corresponding terminal.
Background
In recent years, APT (Advanced Persistent Threat) has become a well-known fashionable term for information security circle, and has become a major security Threat facing various levels of networks and terminal devices. It changes the security threat from random attacks to purposeful, organized, conspired group attacks.
It is difficult to give an accurate definition of APT, which is given by the national institute of standards and technology: an attacker proficient in complex technology utilizes a variety of attack vectors (such as network, physical and fraud) to achieve its own goal with rich resource creation opportunities. These goals typically include tampering with the information technology architecture of the target enterprise to steal data, performing or preventing a task, program, or otherwise preemptively steal data into the other's architecture.
The core of the APT is that a malicious attacker secretly invades and hides for a long time by careful observation, careful layout and various means, searches for confidential data and high-value data, steals the data without triggering any alert, and makes the user unaware that the data is lost. This makes traditional rule-based, knowledge-based firewalls, intrusion detection and prevention systems difficult to trigger, and passive defense methods have been unable to timely and effectively discover the intrusion threats of the APT.
The development and exposure of recent APT attacks has taught us that attackers are constantly finding problems, constantly developing attack weapons, and constantly focusing on targets. Determinacy, similarity and stationarity are fatal safety defects of the existing software system and the architecture information system, and the defects cause that the current software information system is always in a passive close-hit situation, endless loopholes are called, incomplete patches are played, and the strength of a defense system is pursued. However, it is proved once again that advanced protection technology, and tight protection software and system can not stand long-term observation, analysis and repeated attack of attackers, and once attackers get hold, large-area attack spread can be caused.
Reverse engineering is a common basic means for APT attacks, and most attacks are based on reverse engineering. The reverse engineering is simple, namely, the running logic of the program is deduced according to the binary program and the running entity, or the original running logic is tampered according to the running characteristics and rules of the binary program to achieve the purpose of attack. Often, software systems released in the market are all unfamiliar with source codes, and an attacker can only attack the software systems through reverse engineering. Reverse engineering is a complex technology, and is often faced with underlying technologies such as compiling links, byte streams, machine instructions, and the like.
In carrying out the present invention, the inventors have recognized that there is a great need for a method of defending against attacks using reverse engineering in an APT attack to thwart or prevent the effects of existing APT attacks.

The technical solution of the embodiments of the present invention is specifically described below with reference to the accompanying drawings.
The inventor finds that no matter how advanced and rigorous protection technology is, the method cannot stand long-term observation, analysis and repeated attack of an APT attacker, once the attacker is in the hands, the attack spread of a large area is caused, and a new thinking needs to be developed in order to deal with the threat of the APT.
Consider that most software systems have a similar architecture, even the exact same version of software. To conclude this passive tap-and-tap in APT attacks, an unequal game rule scenario, the software security architecture should have new changes, from a deterministic, similar, static existing architecture and architecture to a changing, dynamic system that is difficult for the attacker to observe the analysis and study over a long period of time. On the basis of the traditional protection method, obvious attacks cannot be effective, and the safety of the software information system can be greatly improved by adding a dynamically-changed software system architecture.
Most APT attacks are based on reverse engineering, and if the use of the reverse engineering in the APT attack can be avoided or the use difficulty of the reverse engineering in the APT attack is increased, the existing APT attack effect can be remarkably prevented or prevented.
Based on this, an embodiment of the present invention provides a method for generating mirror image software, as shown in fig. 1, including the following steps:
step S110: and compiling each source code file forming the target software into a corresponding binary file respectively.
To create a target software, a developer writes a text file in assembly and high-level languages according to a certain programming language specification, which contains a series of human-readable computer language instructions that, only after compilation, produce binary code that can be directly recognized by the cpu. In the embodiment of the present invention, during compiling, each source code file is compiled to obtain their binary files, so as to execute step S120.
By way of example, the target software is composed of four source code files of a.c, b.c, c.c and d.c, which are compiled into binary files a.o, b.o, c.o and d.o respectively:
#gcc–c a.c–o a.o
#gcc–c b.c–o b.o
#gcc–c c.c–o c.o
#gcc–c d.c–o d.o
it should be noted that the embodiments of the present invention are applicable to various programming and compiling languages, models and programs, including but not limited to java, BASIC, C + +, C #, Objective-C,. NET, Visual BASIC, PHP, etc.
Step S120: and determining various link sequences of the binary files according to a preset link rule.
The traditional compiling method links binary files in a fixed order, for example, the four binary files a.o, b.o, c.o and d.o are sequentially connected to form an executable file for distribution, the executable files used by all users have no difference, once the executable file of one user is attacked by an APT attacker, the attacking means can be easily copied and used for the executable files of other users, and large-area attack spreading is caused.
In the embodiment of the invention, the preset link rule defines various link sequences of all binary files in the target software, and it can be understood how many executable files can be generated according to the link sequences. Because all the executable files come from the same source code, the running logic and the function of each executable file are the same, but the complete binary files generated are different due to different link sequences, and the internal jump addresses, the code sizes and the instruction execution sequence are different.
Optionally, the preset linking rule includes linking according to a permutation and combination manner of the plurality of binary files.
In the above example, the preset linking rule may specify: by arranging and combining the four binary files a.o, b.o, c.o and d.o of the target software, at least 24 link sequences can be generated, namely, 24 executable files are generated.
In practical applications, a person skilled in the art may define the preset link rule according to practical situations, and is not limited herein.
In the embodiment of the invention, for convenience of management, each link sequence corresponds to a respective identifier, that is, each executable file corresponds to a respective identifier, so that the link sequences can be distinguished conveniently during later management to take corresponding management measures.
Step S130: and linking the plurality of binary files according to any link sequence to generate an executable file of the target software.
Due to the difference of the link sequence, the link steps of the binary files are different.
In the embodiment of the invention, all binary files which are sequentially arranged in the link are respectively connected. In the above example, the four binary files a.o, b.o, c.o and d.o corresponding to the 24 link orders of the target software permutation and combination are respectively connected:
#gcc a.o b.o c.o d.o–o app01.exe
#gcc b.o a.o c.o d.o–o app02.exe
#gcc a.o c.o b.o d.o–o app03.exe
#gcc a.o b.o d.o c.o–o app04.exe
……
#gcc d.o c.o b.o a.o–o app24.exe
when a product is released, each executable file of the target software enters the market according to a preset release rule, so that the final target software in the market has a wide variety of mirror image software products, and an APT attacker is confused and confused when attacking the target software, cannot find a rule and cannot effectively compare the target software with the target software. Even if the APT attacker tamps some instructions after successfully reverse-engineering one executable file to achieve the purpose of attack, the same tampering strategy cannot be applied to all executable files of the target software.
The type of the exe file of the executable file is only an example, and may also be a type of sys file, a type of com file, a type of elf file, a type of apk file, a type of ipa file, and the like, and is not limited herein.
In a preferred embodiment of the present invention, as shown in fig. 2, step S110 may specifically include:
step S111: and determining the compiling parameters corresponding to the plurality of compiling modes of any source code file.
By adopting different compiling methods, binary structures in the same source code file can be different. In the embodiment of the present invention, for any source code file, the compiling parameters corresponding to the multiple compiling modes of the source code file are determined, so as to execute step S112 to generate multiple binary file versions of the source code file.
Optionally, different compilation methods correspond to different levels of optimization of the source code file. The optimization levels may respectively correspond to the degree of disorder of the binary structure, for example, a compiling method with a higher optimization level requires more complex compiling parameters, but can make an APT attacker have higher difficulty. The person skilled in the art can match the appropriate optimization level for the target software in different fields or scenes according to the actual situation.
Specifically, when mirror image software is manufactured, aiming at any source code file of target software, the optimization level of the source code file is determined; and acquiring the compiling parameters of the corresponding compiling mode according to the optimization level so as to execute the step S112.
Step S112: and compiling the source code file according to the compiling parameters of any compiling mode to obtain a binary file corresponding to any compiling mode.
As an example, 4 compilation modes of the source code file a.c are determined, and the a.c is compiled by using the compilation parameters of the 4 compilation modes respectively:
#gcc–O1a.c–o a1.o
#gcc–O2a.c–o a2.o
#gcc–O3a.c–o a3.o
#gcc–O4a.c–o a4.o
in practical application, different mirror image target software generation schemes can be formulated by combining with a preset link rule, and the embodiment of the invention at least comprises any one of the following steps:
(1) the preset linking rule may only define one linking order, and only generate the mirror image target software through different compiling modes of any source code file, for example:
#gcc a1.o b.o c.o d.o–o app01.exe
#gcc a2.o b.o c.o d.o–o app02.exe
#gcc a3.o b.o c.o d.o–o app03.exe
#gcc a4.o b.o c.o d.o–o app04.exe
……
(2) the preset linking rule may only define one linking sequence, and different compiling manners are respectively adopted for combining a plurality of source code files to generate mirror image target software, for example:
#gcc a1.o b1.o c.o d.o–o app01.exe
#gcc a1.o b2.o c.o d.o–o app02.exe
#gcc a1.o b3.o c.o d.o–o app03.exe
#gcc a2.o b1.o c.o d.o–o app04.exe
#gcc a2.o b2.o c.o d.o–o app05.exe
#gcc a2.o b3.o c.o d.o–o app06.exe
……
(3) the preset linking rule defines a plurality of linking sequences, but each source code file only adopts one compiling mode to generate the mirror image target software, for example:
#gcc a.o b.o c.o d.o–o app01.exe
#gcc b.o a.o c.o d.o–o app02.exe
#gcc a.o c.o b.o d.o–o app03.exe
#gcc a.o b.o d.o c.o–o app04.exe
……
(4) the preset linking rule defines a plurality of linking sequences, and any source code file is combined to generate mirror image target software by adopting different compiling modes, for example:
#gcc a1.o b.o c.o d.o–o app01.exe
#gcc a2.o b.o c.o d.o–o app02.exe
#gcc b.o a1.o c.o d.o–o app03.exe
#gcc b.o a2.o c.o d.o–o app04.exe
……
(5) the preset linking rule defines a plurality of linking sequences, and the source code files are combined to generate mirror image target software in different compiling modes, for example:
#gcc a1.o b1.o c.o d.o–o app01.exe
#gcc a1.o b2.o c.o d.o–o app02.exe
#gcc a2.o b1.o c.o d.o–o app02.exe
……
#gcc d.o c.o b2.o a2.o–o appN.exe
……
the quantity and the content of the mirror image target software generated by the various schemes are different, but the APT attacker can be confused and confused when attacking the target software to different degrees, cannot find the law, and cannot effectively compare the target software. Even if the APT attacker tamps some instructions after successfully reverse-engineering one executable file to achieve the purpose of attack, the same tampering strategy cannot be applied to all executable files of the target software.
In another preferred embodiment of the present invention, the redundant files may also be randomly inserted during the linking, that is, in step S130, at least one redundant file is inserted at any position of the plurality of binary files arranged according to any linking order, and linked to an executable file of the target software.
Illustratively, redundant files X.o are inserted and linked in the sequential arrangement of one executable file by binary files a.o, b.o, c.o, d.o:
#gcc a.o b.o c.o X.o d.o–o app.exe
where redundant files are not actually executed, but serve the purpose of confusing an attacker.
Specifically, the redundant file may be further derived from any one of the aforementioned mirror target software generation schemes, and the specific redundant file insertion manner includes, but is not limited to, setting the number of redundant files, the content of the redundant files, the location where the redundant files are inserted, and the like.
According to the generation method of the mirror image software, provided by the embodiment of the invention, each source code file forming target software is compiled into a corresponding binary file respectively; determining a plurality of link sequences of the binary files according to a preset link rule; linking the plurality of binary files according to any link sequence to generate an executable file of the target software; therefore, the binary image executable files with multiple versions and consistent target software functions are generated, APT attackers are difficult to find attack rules and give up, and even if APT attackers obtain a certain binary executable file and successfully attack the binary executable file by adopting reverse engineering, other binary executable files of the same target software cannot be referred to, the same attack method is prevented from spreading, the reverse APT attack difficulty is effectively increased, and the safety of various levels of networks and terminal equipment is improved.
In order to further increase the difficulty of APT attack, an embodiment of the present invention further provides an update method of an executable file, including:
and when a preset updating condition is met, updating the original executable file of the target software based on any executable file of the target software generated by the method.
Wherein the predetermined update condition includes: a sensitive time window and/or a predetermined time period.
With the short-term inability of APT attackers to achieve ultimate attack goals, previous partial attack efforts are defeated by changing the binary structure (even if the functional logic is unchanged).
According to the generation method of the image software, a compiling system is comprehensively established, the system can directly generate binary images of multi-version target software based on homologous codes, and the binary images are the same target software and belong to different product individuals. And updating and upgrading according to a preset updating condition, so that part of attack achievements of attackers can be continuously invalidated, the threat of reverse engineering in the APT attack is finally hindered, and the severity and the danger of the reverse engineering are completely eradicated.
