Description

Technical field

The invention relates to computer security, and more particularly to systems and methods for ensuring the security of online transactions.

State of the art

Currently, there are a large number of software with which you can conduct various online transactions. Many transactions are made using online banking using standard browsers, and individual banking clients are also used, which are especially popular on mobile platforms. Other applications related to online transactions include electronic currency systems, such as BitCoin, or online games that use their own microtransaction system, during which the user buys in-game items or in-game currency using real funds (for example, using your bank card).

It is not surprising that with the growth of online payments, this segment of services has become interested in attackers who are actively exploring possible options for intercepting these transactions with the aim of illegal transfer of funds. As a rule, the theft of such data is carried out with the help of malicious programs that get on users' computers (infect them). Most often, such programs get to computers through infection of popular Internet browsers, intercept data entered from input devices (such as a keyboard or mouse), or intercept data sent to the network. For example, malicious programs that infect browsers gain access to browser files, view browsing history and saved passwords when they visit web pages. Data entry interceptors (English keyloggers) intercept data input from the keyboard or mouse, take screenshots (English screenshots) and hide their presence in the system using a number of rootkit technologies (English rootkit). Similar technologies are also used in the implementation of network packet sniffers (traffic sniffers), which intercept transmitted network packets, extracting valuable information from them, such as passwords and other personal data. It is worth noting that the infection most often occurs using vulnerabilities in software that allow the use of various exploits (English exploit) to infiltrate a computer system.

Existing anti-virus technologies, such as the use of signature or heuristic checks, proactive protection methods or the use of trusted application lists (whitelist), although they can detect many malicious programs on users' computers, are not always able to determine their new modifications, the frequency of which growing day by day. Thus, solutions are required that could secure the procedure for making online payments to users.

There are various solutions that aim to secure online transactions. A possible solution to counter malware that intercepts data input from input devices is to use secure input devices. An example of such devices is a keyboard with encryption of input data or a virtual keyboard (http://support.kaspersky.com/kav2012/start?qid=208284630). Such solutions have several disadvantages: for a keyboard with encryption of input data, there may also be interceptors that intercept data before encryption or after decryption, and the virtual keyboard can be compromised by using malicious programs that take screen shots at specified intervals.

The application US 20060136332 describes the use of the bundle "secure transaction support device plus software client on the computer" to ensure transaction security. The software client works transparently for the user. A secure device contains a set of algorithms to ensure the security of each known type of transaction. However, the application does not address the issue of analyzing the security of the computer as a whole, i.e. in the presence of unknown malware, user input may be compromised. WO2005033943 describes a service for analyzing a payment system web server for vulnerabilities (for example, open ports). Visitors to the web server (i.e., service customers) will be displayed with information about the vulnerabilities found, however, the users themselves must take further actions. US 8024790 describes a mechanism for determining that a URL is important from the point of view of user input for further security measures, which may not be possible if the address was compromised (phishing site) or not marked by user as important.

However, it is worth noting that the publications cited do not disclose a comprehensive approach to ensure secure online payments, since each publication solves one of the problems associated with the safe conduct of online transactions, but leaves others unresolved, which does not allow us to say that the user is on the side You can safely conduct online transactions.

An analysis of the prior art and the possibilities that arise when combining existing solutions in one system, allows you to get a new result, namely the system and method of ensuring the safety of online transactions.

Description of Embodiments

The objects and features of the present invention, methods for achieving these objects and features will become apparent by reference to exemplary embodiments. However, the present invention is not limited to the exemplary embodiments disclosed below, it can be embodied in various forms. The essence described in the description is nothing more than the specific details necessary to assist the specialist in the field of technology in a comprehensive understanding of the invention, and the present invention is defined in the scope of the attached claims.

On figa shows a typical scheme for conducting online transactions. The user 100, using the software input tool, enters all the necessary information into the application 120 for conducting online transactions. As a means of entering software, you can consider devices such as a keyboard, mouse, touch screen, which imply data input by the user. The application 120 for conducting online transactions can be either a browser in which an online transaction can be made from a specific web page, or a specialized banking client, as well as any other application that has online transaction functionality (for example, the World gaming application of Warcraft has its own service for buying virtual things for money). In order for an online transaction to be successful, you need to connect to the Internet 130 through which you can transfer funds using payment service 140. In this case, a payment service refers to the entire infrastructure for money transactions, including, for example, the bank’s infrastructure - the issuer of the payment card, the executing bank and any other intermediaries.

Fig. 1b illustrates possible threats for online transactions. One of the possible threats 110a is malicious (most often trojan) programs, such as data entry interceptors (keyloggers), which intercept keyboard or mouse input, take screenshots (English screenshots). Interception of data input can be implemented using a library (Eng. Dynamic Load Library, DLL), which sets up event hooks. Keyboard input tracking can only occur in windows with certain titles (i.e., targeted tracking of applications 120 takes place). The malware 110a stores the collected information about the input in a separate file, so that it can then be transferred to the attacker side using, for example, email. It is worth noting that malware 110a uses a number of technologies to hide its presence in the system (for example, rootkit technology) or to make it difficult for antivirus applications to detect it (for example, using code obfuscation). Also, threats 110a can use system interceptors (for example, for the Windows operating system, these can be interceptors on the HttpSendRequestW (), HttpSendRequestAQ, HttpOpenRequestA () API functions) to track network requests from application 120.

Another example of a threat is a compromise of application 120 using malicious 110b functionality. This functionality 110b can have a different nature, for example, it can be an infection of the application executable 120 with a virus, or it can be the addition of a DLL module (English Browser Helper Object, VNO) to the browser process. Other implementations of functional 110b may be based on exploiting vulnerabilities in application 120, introducing application 120 into the address space of a running process, etc.

Another example of computer threats are malware 110v, which are aimed at intercepting and spoofing network traffic from applications 120. Intercepting and spoofing can be implemented by adding fake SSL certificates for certain sites, adding DNS records for network settings (LAN, Wi -Fi), changes to the hosts file, etc. These approaches are aimed at redirecting the user (or rather, application 120) not to the payment service 140, but to a malicious web resource 110g (usually these are phishing sites), which may be similar functionality for online transactions, but in this case, the user agent 100 will be transferred to the malicious accounts. The malicious web resource 110g may also have consonant domain names for payment services 140, have the same interface, which can mislead user 100. Another variant of the operation of malicious applications 110v is to change the response from the payment service 140, for example, by replacing a web page or adding a malicious script.

The threats listed above 110a-110g very often do not work as separate applications, but act as a whole complex of related threats for illegal online transactions. This is due to the fact that the means of protection against such transactions are also constantly being improved - banks and payment service owners 140 improve the quality of work by adding, for example, new user authentication methods, anti-virus companies are constantly adding new methods for detecting threats 110a-110g. However, even if it turns out to prevent the work or use of almost all threats, even one threat can lead to an unexpected online transaction or the important data being stolen from the user. Thus, an integrated solution is required to detect, neutralize or circumvent existing threats 110a-110g.

Figv illustrates a set of necessary tools for protecting online transactions in the framework of the implementation of the present invention. In order to avoid possible interception of data through the input means 110, the user 100 is provided with means for secure data input 120a. Typically, such a tool is implemented in the form of a virtual keyboard (http://www.techopedia.com/definition/716/virtual-kevboard), which may contain a number of improvements for additional protection against keyloggers, for example, in the form of protection from screenshots ( using interception and blocking of screenshots that are performed without using the PrtScr key on the keyboard, as well as other standard key combinations: Alt + PrtScr; Ctrl + PrtScr). Other embodiments of the secure data entry tool 120a may also be hardware data input devices with a separate driver in the operating system (OS) for translating the input from the tool 120a into the character set for application 120. Also, the implementation of the tool 120a can use buffer protection approaches exchange, for example, controlling the transfer of data between different processes and the process of the application 120. For example, the tool 120a can block access to the clipboard for all applications except the application 120 a number of isolated processes (for example, Notepad application process or foreground process, where the user can copy the necessary data).

In order to exclude possible compromise of application 120, a secure environment 120b is used, which can be implemented in the form of a number of technologies:

- Using sandbox technologies (http://www.techopedia.com/detinition/27682/sandbox-computer-securitv) .;

- Protection of the running process of the application 120 by checking (prohibiting) changes in the address space of the process (i.e., preventing code injection), analyzing the launch of new threads within the application 120, etc .;

- Tracking of suspicious operations when executing threads of a running application process 120. Such tracking can be implemented using the technologies described in patent application US 20110083176. In this approach, the following operations to the process of application 120 from other processes can be prohibited: code injection, direct access to memory, taking screenshots, attempts to access child processes of the application process 120;

- Using a virtual machine in which application 120 will be launched;

- Launching another application to implement the capabilities of the application 120. For example, in the case of a browser, this may be the use of a simplified version of the browser that implements a minimum set of functionality for conducting online transactions (sending and receiving web requests, displaying web pages, authorization and working with SSL protocol, etc.).

In order to avoid possible interception and / or modification of data that will be sent by application 120 via the Internet 130 to the payment service 140, a secure data transfer means 120b can be used that allows the following functions to be performed:

- Tracking and verification of the domain name of the payment service 140 in order to identify malicious web resources 110 g. The database of malicious web resources is maintained by many developers of anti-virus products (for example, McAfee, Symantec, Kaspersky Lab);

- Verification of digital certificates of payment services using the approaches described, for example, in patent US 7739494;

- Verification of the content (content) of the payment service, for example, using the technology disclosed in patent US 8370939.

Figure 2 shows a system for protecting online transactions in the framework of the implementation of the present invention. User 100 uses a computer 200 on which OS 210 is installed to work with applications 220, of which at least one application 120 allows online transactions. The risk assessment tool 230 analyzes the OS 210 and application 120 for vulnerabilities, configuration files, a list of installed drivers and running services, and other data related to computer security in order to determine the risk of a possible online transaction. Risk assessment can be performed using a number of metrics, for example, using the Common Vulnerability Scoring System (CVSS), which can include detailed information about vulnerabilities (criticality, possible consequences of using the vulnerability, ways to eliminate the vulnerability). Examples of criteria for a risk assessment tool to work:

- Vulnerabilities (criticality, possible consequences of using the vulnerability), including vulnerabilities of application 120 for conducting online transactions;

- Incidents on the local computer 200 (detection of malware, network attacks, spam, etc.);

- Incidents in the network in which the computer 200 is located (network attacks, denial of service, etc.);

- Status of anti-virus software (time of the last update of anti-virus databases, availability of anti-virus servers for requests, etc.);

- Using hardware authentication. When using such tools, the possibility of compromising an online transaction is reduced, therefore, the risks are reduced;

- Frequency of online transactions. With an increase in the frequency of online transactions on the part of the user, as a rule, the risk of conducting unauthorized transactions increases, which the user may not notice right away due to the large number of transactions;

- User behavior that can characterize him as a user with the risk of infection by unknown malware. One approach described in US Pat. No. 8312536 evaluates a user's reputation based on the reputation of the data that the user operates during their work, such as files or sites. The more malicious data is found among such data, the worse the user's reputation may turn out to be, which increases the risk when conducting an online transaction.

In one embodiment, the risk assessment tool can only close the vulnerabilities found by downloading and installing updates (patches) for vulnerable applications, and changing the application’s settings to reduce the risk when conducting online transactions.

The following are the main risks associated with online transactions:

- Loss of personal data, such as user identification information;

- Incorrect conduct of the current online transaction;

- Obtaining unauthorized access by third parties to the means of storage and conducting online transactions, for example, to applications 120, electronic wallets (English digital wallet).

Risk assessment tool 230 can calculate the risk of online transactions according to certain metrics, and the risk value can be expressed as a number or a specific value. An example of the risks is given below in table 1.

Table 1. Conditions Risk (number) Risk (value) Application 120 is made as a separate application for conducting a certain type of online transaction; Hardware confirmation of online transactions; The anti-virus application has the latest version of anti-virus databases. one Low Application 120 is in the form of a browser; Confirmation of transactions occurs through data entry from the keyboard by the user; The anti-virus application has the latest version of anti-virus databases. 2 Average Application 120 is in the form of a browser; Confirmation of transactions occurs through data entry from the keyboard by the user; The anti-virus application has an outdated version of anti-virus databases; A number of malware incidents have been identified. 3 Tall

After the risk assessment tool 230 has determined the risks of online transactions, it transmits this information to the control tool 240, which controls the operation of the secure data entry 120a, the secure environment 120b and the secure data transfer means 120b. Depending on the information received, the control means 240 may adjust the aforementioned means as follows:

- the means for secure data entry 120a can be either turned off (if you do not need to use data input from the user himself, for example, when using online transaction confirmation hardware), and it is turned on, depending on a number of conditions, which include information about the application 120 (type of application, vulnerabilities, the need to enter data, etc.), OS 210, etc .;

- protected environment 120b can use various approaches to protect application 120 (using the sandbox or virtual machine, controlling the execution of process threads, etc.), the higher the level of risk, the more reliable the protected environment 120b is used (for example, at a high level of risk use a separate virtual machine, network connections will be established through a separate VPN connection, while at a low level of risk there may be no secure environment at all);

- 120v secure data transfer means can operate not only with the risk level for checking the transmitted data, but also with information about the application 120 used (for example, when using a browser, the URLs that are accessed during online transactions, digital certificates of payment sites will be checked service 140, etc.).

It is worth noting that all settings of the means for secure data entry 120a, the secure environment 120b and the means for secure data transfer 120v can be changed by the user or administrator to simplify the process of conducting online transactions. To this end, the control tool 240 may have its own interface (Eng. Graphics User Interface, GUI). In a preferred embodiment, the control means 240, the means for secure data entry 120a, the secure environment 120b, the means for secure data transmission 120b, the risk assessment means 230 are implemented as a separate application or may be part of an anti-virus application. The management tool 240 is also intended to determine the start of an online transaction for activating the means for secure data entry 120a, secure environment 120b, means for secure data transfer 120b, risk assessment tools 230 both individually for each of the above, and all together.

To obtain information about vulnerabilities, malicious applications, and other information related to the security of online transactions, the control tool 240 contacts the reputation service 250. Such services can be implemented as a remote cloud service or as a local database, which contains the following information:

- information about vulnerabilities;

- phishing database sites;

- database of digital certificates;

- heuristic rules for detecting phishing sites of payment services, as well as malicious scripts that can be executed when accessing such sites;

- rules for setting funds 120a-120v.

Figure 3 illustrates the method of operation of the present invention. At step 310, a start of an online transaction is determined, which may be based on:

- launch the application 120;

- determining the start of an online transaction through application 120;

- user selection (the user can independently choose the online transaction protection mode using this system).

The following signs may serve as an example of the moment of starting an online transaction in the case of a web browser: opening the well-known web page of the payment service 140 (in the case of online banking, this will be the bank's website), establishing an https connection, the presence on the page of characteristic fields for entering data ( Login: Password).

The user can also set the start of a transaction also in those cases when training is required to identify similar cases in the future. The following factors can be used for training:

- requests to network resources that may belong to financial institutions (for example, to banks' sites) for correctly identifying them as payment services 140 in the future. In the case of a browser, this can be access to sites such as ebay.com, walmart.com, bestbuy.com, newegg.com and other similar ones;

- the presence in the active application window of 120 elements with the ability to enter data, while the elements can have characteristic names (identifier, login, password, ID, etc.) and contain other properties indicating the possibility of entering data (for example, for an HTML element entering a password in the text field also contains the value type = "password");

- information about the application 120, which defines it as an application for conducting online transactions. For example, for an individual bank client by digital signature, you can verify that the digital signature belongs to the bank, which will indicate that this client is most likely to be used for online transactions.

After the start of an online transaction has been determined at step 310, an optional step follows to determine the risks of an online transaction at step 320. At this stage, the risks of an online transaction can also be mitigated by installing updates to close vulnerabilities or notifying the user of the risk . Next, at step 330, a secure environment is organized for the application 120. This step can be carried out in advance, even before the start of the online transaction. Then, at step 340, the user enters data for an online transaction using the secure data entry tool 120a. For secure data transmission over the network at step 350, in addition to the above approaches (checking domain names, digital certificates, etc.), a secure connection (for example, a VPN connection) can also be used, where the current connection to the payment service will be encapsulated. After all the data has been transferred and the transaction has been completed, at step 360, the system stops working. It is worth noting that steps 330-350 need not be followed exactly in the sequence shown in FIG. 3, for example, the information about the payment service 140 that the application 120 is trying to access can be checked first, and only then a secure environment will be provided and secure data entry.

In one embodiment, to protect browser-based web banking, the method of operation of the present invention may look as follows:

- Opening an Internet connection;

- Checking the compliance of the requested web page with the bank's website;

- Establishing the authenticity of the resource by verifying the digital certificate;

- Analysis of vulnerabilities in OS 210;

- Blocking the use of the bank’s web page in unprotected mode;

- Launching a secure browser, which displays only the field required to enter web banking;

- Protection of user data input during a session with web banking;

- End a secure session when closing the browser.

Figure 4 represents an example of a general-purpose computer system, a personal computer or server 20 comprising a central processor 21, a system memory 22 and a system bus 23 that contains various system components, including memory associated with the central processor 21. The system bus 23 is implemented like any bus structure known in the art, which in turn contains a bus memory or a bus memory controller, a peripheral bus and a local bus that is capable of interacting with any other bus architecture. The system memory contains read-only memory (ROM) 24, random access memory (RAM) 25. The main input / output system (BIOS) 26 contains the basic procedures that ensure the transfer of information between the elements of the personal computer 20, for example, at the time of loading the operating system using ROM 24.

The personal computer 20 in turn contains a hard disk 27 for reading and writing data, a magnetic disk drive 28 for reading and writing to removable magnetic disks 29, and an optical drive 30 for reading and writing to removable optical disks 31, such as a CD-ROM, DVD -ROM and other optical information carriers. The hard disk 27, the magnetic disk drive 28, the optical drive 30 are connected to the system bus 23 through the interface of the hard disk 32, the interface of the magnetic disks 33 and the interface of the optical drive 34, respectively. Drives and associated computer storage media are non-volatile means of storing computer instructions, data structures, software modules and other data of a personal computer 20.

The present description discloses an implementation of a system that uses a hard disk 27, a removable magnetic disk 29, and a removable optical disk 31, but it should be understood that other types of computer storage media 56 that can store data in a form readable by a computer (solid state drives, flash memory cards, digital disks, random access memory (RAM), etc.) that are connected to the system bus 23 through the controller 55.

Computer 20 has a file system 36 where the recorded operating system 35 is stored, as well as additional software applications 37, other program modules 38, and program data 39. The user is able to enter commands and information into personal computer 20 via input devices (keyboard 40, keypad “ the mouse "42). Other input devices (not displayed) can be used: microphone, joystick, game console, scanner, etc. Such input devices are, as usual, connected to the computer system 20 via a serial port 46, which in turn is connected to the system bus, but can be connected in another way, for example, using a parallel port, a game port, or a universal serial bus (USB). A monitor 47 or other type of display device is also connected to the system bus 23 via an interface such as a video adapter 48. In addition to the monitor 47, the personal computer can be equipped with other peripheral output devices (not displayed), for example, speakers, a printer, etc. .

The personal computer 20 is capable of operating in a networked environment, using a network connection with another or more remote computers 49. The remote computer (or computers) 49 are the same personal computers or servers that have most or all of the elements mentioned earlier in the description of the creature personal computer 20 shown in Fig.4. Other devices, such as routers, network stations, peer-to-peer devices, or other network nodes may also be present on the computer network.

Network connections can form a local area network (LAN) 50 and a wide area network (WAN). Such networks are used in corporate computer networks, internal networks of companies and, as a rule, have access to the Internet. In LAN or WAN networks, the personal computer 20 is connected to the local area network 50 via a network adapter or network interface 51. When using the networks, the personal computer 20 may use a modem 54 or other means of providing communication with a global computer network such as the Internet. The modem 54, which is an internal or external device, is connected to the system bus 23 via the serial port 46. It should be clarified that the network connections are only exemplary and are not required to display the exact network configuration, i.e. in reality, there are other ways to establish a technical connection between one computer and another.

In conclusion, it should be noted that the information provided in the description are examples that do not limit the scope of the present invention defined by the claims.
