Recent times have been quite eventful for cybersecurity specialists. The world witnessed a number of cyber-attacks; thereby creating a need for adoption of advanced cybersecurity solutions.

Here is a brief description about some significant breaches that happened recently:

• SolarWinds: In this attack, hackers were able to successfully compromise the infrastructure of a company named SolarWinds. The company produces a network and application monitoring platform known as Orion. After compromising the company’s infrastructure, the attackers used their access to distribute compromised version of the software to the users including 425 of Fortune 500 companies, top ten telecommunication companies of US, top five US accounting firms, hundreds of colleges worldwide, etc. Malware infected version of Orion was used to successfully breach a cyber-security company known as FireEye. Another malware known as Supernova also used the compromised Orion version as the delivery method to infect its victims.
• Software AG: Software AG is the second largest software vendor in Germany and seventh largest in Europe. It was hit by Clop ransomware attack in October 2020. The attackers demanded $23 million as ransom.
• Sopra Steria: It is a European IT firm that provides an array of IT services, including consulting, systems integration, and software development. In October 2020, the company was attacked by a new version of Ryuk ransomware.
• Telegram: A group of hackers that had access to the system used for connecting mobile networks across the world were able to gain access to Telegram messenger and email data of high-profile individuals in the cryptocurrency business.

Formulating new cyber security strategies and updating existing protocols is necessary for staying protected against cyber-attacks. A great way to do so is to observe the cyber-attacks and understand the new techniques being used. Recent cyber-attacks have shown that ransomware and social engineering attacks are gaining momentum. In terms of defensive actions, SolarWinds attack has indicated that third party risk management needs to be prioritized. Protecting remote endpoints and workers has emerged as next priority. Automated response systems should be used to improve the response time for preventing lateral infections through the network.

A ransomware is a malicious program that infects a target device and gains control. The program encrypts files and blocks the user access to the infected data (or system) until the targeted organization pays the ransom to the attackers. Although the instances of ransomware attacks have gained momentum lately, it is actually a primitive cybersecurity threat.

Here is a brief account of history of ransomware:

• First Ransomware: The first known ransomware attack was recorded in 1989. The attack was carried out by Joseph Popp, an AIDS researcher. He distributed 20,000 floppy disks containing a malicious program to AIDS researchers across 90 countries. He made pretence that the floppy disks contained a survey program. It was a basic ransomware attack and since then ransomware attacks have evolved and have acquired an array of advanced features.
• Locker Ransomware: In 2007, a new category of ransomware malware appeared. It was known as Locker Ransomware. This type of ransomware did not encrypt files; instead it locked the victim out of the device preventing him from using it. Another ransomware that operated on this technique is known as WinLock. The ransomware employed worms such as Citadel, Lyposit, and Reveton for displaying a fine message from a law enforcement agency. The ransomware demanded $10 as ransom in exchange for the unlocking code.
• Scareware: After a few years, the attackers changed their strategy. They started capitalizing on the fear of ransomware by spreading fake applications and antivirus programs. In these types of ransomware attacks, the malicious applications attack a target device and display a pop up message saying that the device has been infected with viruses. The message encourages the victim to visit a website and pay for antivirus software for fixing the problem. The link mentioned in the message redirects the user to a malicious website designed to look authentic and legitimate. After a few years, cyber criminals understood that they can compromise any website instead of designing fake websites. They switched to automated ransomware attacks the included phishing emails as vectors.
• Crypto Ransomware: In 2013, first cryptographic ransomware emerged. It was known as CryptoLocker. It was launched by Gameover ZeuS bot and was sent as an email attachment. Once downloaded, the ransomware encrypted the files on the device and demanded a bitcoin payment for unlocking the files.
• Ransomware-As-A-Service: It is the latest step in the evolution of ransomware. It first appeared in 2015 with the Tox toolkit launch. This gave beginner cybercriminals a chance to develop custom ransomware tools with advanced capabilities.

The year 2020 has witnessed a shift in the digital ecosystem as major number of employees have taken a turn towards working from home. Thus, most organizational networks are now being accessed remotely by employees sitting at diverse locations spanning across the globe. This has given rise to new opportunities for hackers who are exploring different techniques to disrupt the vulnerable networks.

Here is a list of popular modern hacking techniques:

• H2C Smuggling: H2C stands for HTTP/2 cleartext. These attacks abuse H2C unaware front-ends to create a tunnel to backend systems. This enables the attackers to bypass frontend rewrite rules and exploit internal HTTP headers.
• Portable Data exFiltration: Cross Site Scripting (XSS) attacks are extensively being used to compromise data stored in PDF files and exfiltrate it to a remote server. The rate of these attacks has extensively increased with the increasing popularity of server-side PDF generation such as generation of e-tickets, boarding passes, etc. These PDF documents often contain sensitive information including bank details, passport numbers, addresses, and other personal data. In this attack, a malicious injection vector is injected into the PDF. When a user clicks on the link or anywhere in the PDF, the hacker can extract all the sensitive information entered by the user.
• TLS Attacks: Exploiting features of TLS (Transport Layer Security) makes it possible to land Server Side Request Forgery attacks. The attack technique involves exploiting technologies involved with TLS session caching. The hacker can manipulate the session to send a TLS session ID ticket or psk (pre-shared key) identity to his server.
• NAT Slipstreaming: NAT slipstreaming exploits the victim’s browser in conjunction with the Application Level Gateway (ALG) connection tracking mechanism built into NATs, routers, and firewalls. This is done by chaining internal IP extraction via timing attack or WebRTC, automated remote MTU and IP fragmentation discovery, protocol confusion through browser abuse, etc. As the destination ports are opened by NAT or firewall, this helps in bypassing any browser-based port restrictions.

Understanding of the hacking techniques is essential to formulate effective prevention strategy against modern hacking attacks. An effective prevention strategy is important to ensure the safety of organization’s network and individual user systems. A loophole in the cyber security strategy can cause major losses in terms of stolen data, user information, business secrets, etc.

In a practical environment, a cyber security strategy is actually an amalgamation of multiple strategies. Cyber security professionals employ different strategies in coordination with each other in order to ensure a multidimensional protection against cyber threats.

Here is a brief guide to cyber security strategies:

Creating A Secure Cyber Ecosystem: The cyber ecosystem involves a wide range of entities including devices, individuals, management, private organizations, etc. which interact with each other. This strategy emphasizes on having a robust cyber ecosystem that would permit its devices to interact in a secure manner. A strong cyber ecosystem has three symbiotic structures – automation, interoperability, and authentication.

Creating An Assurance Framework: The basic objective of this strategy is to design an outline in compliance with global security standards. The framework that is designed is in compliance with industry wide standards, guidelines, and practices. These parameters help businesses to manage cyber security related risks.

Encouraging Industry Standards: Standards help in defining the outline of how an organization approaches the information security related issues. Implementation of cyber security standards enhance the efficiency of security processes, enable systems incorporations, provide a medium to test new applications, organize the approach to arrange new technologies in the cyber framework, etc.

Creating Mechanisms For IT Security: Different IT security mechanisms differ in their internal application features and attributes of security they provide. Following are the common IT security mechanisms:

• Link Oriented Measures
• End-To-End Measures
• Association-Oriented Measures
• Data Encryption

Protecting Critical Information: Critical information such as user data, login credentials, financial data, business trade secrets, etc. is the backbone of any organization. Safeguarding critical information against growing cyber threats needs a structured approach. This strategy can be implemented via following steps:

• Defining critical information
• Categorizing the available information
• Prioritizing information categories
• Securing the most critical information
• Testing the framework
• Securing the second category and repeating the cycle

Security As A Service: SaaS providers offer a cyber security solution with different attributes to meet diverse cyber security needs of organizations. This strategy can be implemented based on 5 C’s:

• Change – Organizations face changing pressures from different sources such as competitive threats, new regulations, internal threats, cyber threats, etc. SaaS model enable organizations to respond to these changes quickly.
• Compliance – SaaS solutions are designed keeping in mind the governances, regulations, etc.
• Cost – SaaS provides an alternative cyber security solution allowing the in-house IT teams to focus on core business.
• Continuity – Multi-tenant SaaS services are hosted in highly reliable data centers with built-in redundancy.
• Coverage – SaaS solutions offer clear benefits with geographically dispersed sites allowing easy management of remote users.

SQL injection (SQLi) attacks exploit existing vulnerabilities to alter SQL queries by injecting malicious code. If successful, SQL injection attacks can allow the cyber attackers to modify database information, access sensitive data, execute administrator tasks on the database, and recover files from the target system. In extreme cases, attackers can also issue commands to the database operating system.

In order to defend against SQL injection attacks, it is imperative to understand the working of the attack.

How Does A SQL Injection Attack Work?

Cyber criminals may use several different types of SQL injections to execute an attack. Here are some common variants of SQL injections:

• SQL Injection Based On User Input: In this type of SQL attack, the user inputs are used to inject malicious code and gain access to the system. Web applications accept user inputs via forms. The information collected by these forms is then passed on to the database for processing. If the web application server does not screen the forms, the attacker can inject SQL statements via user input form fields and delete, copy, or modify the contents of the database.
• SQL Injection Based On Cookies: In this approach to SQL injection, the cookies are modified to infect database queries. Web applications often load cookies to use data stored in them as part of database operations. The malicious users or a malware installed on the system can modify the cookies to inject SQL statement in the backend database. Once infected, cyber attackers can access the database to steal, modify or delete the data stored in the database.
• SQL Injection Based On HTTP Headers: Some web applications are designed to accept inputs from HTTP headers. In such cases, malicious actors create fake headers containing arbitrary SQL statements. When the web application accepts input from these fake HTTP headers, the malicious code is injected into the database.
• Second Order SQL Injection: These are most complex SQL injection attacks because they are designed in a way that allows the SQL code to lie dormant in the system for a long time.

What Is The Impact Of SQL Injection Attacks?

SQL injection attacks can cause various harms to the victim system:

• Steal user credentials resulting in identity theft.
• Access information stored in database server.
• Alter or add new information to infected database.
• Delete database records leading to DoS attacks.

History Sniffing is an umbrella term that defines different techniques used to monitor the web browser history for diverse purposes including the launch of a cyber attack. Although it is an old trick, the technique is still being used for victimizing internet users. In the recent times, studies have shown a rise in the types and numbers of history sniffing cyber attacks for the sheer ease of launching such attacks.

How Is History Sniffing Cyber Attack Launched?

• The cyber attackers create fake online advertisement and preload attacker code in this ordinary looking advertizement.
• The code is embedded with a list of target websites (the websites that hackers want to know if the user has visited).
• When user clicks on the advertizement, the code starts running and checks the browsing history for target websites.
• If the user has visited any of the target websites, the program will indicate a match to the hacker.
• The hackers then redirect the victim to corresponding fake version of the website to cause further damage.

How Are History Sniffing Attacks Used?

The data collected by history sniffing attacks is used as a foundation for other types of cyber attacks by hackers.

• Phishing: Hackers use history sniffing techniques to find out the financial organization websites visited by the victim. This data is then used to launch customized phishing attacks which automatically match every victim to a fake page of actual financial organization. The victims are tricked into filling their financial details which can be used by hackers to steal money from users’ accounts.
• Stalking: History sniffing can be used to stalk internet users by keeping an eye on their browsing behavior. Hackers may keep a track of social media pages or locations saved in the browser history. Stalking may cause some serious problems for the victim such as kidnapping, physical damage, assault, etc.
• Identity Theft: It is common for internet users to save their login details or choose the option to ‘keep Logged In’ on their browser. Hackers can use history sniffing coupled with other malicious code to check the social media profiles logged in on the browser and access these profiles to pose as the user. They can further use these accounts to send unauthorized messages, post fake news, etc.

With increasing use of internet, there has been an alarming increase in number of cybersecurity threats. In addition to number, the risk and severity of cybersecurity threats has also increased. Advancement of technology and wide use of digital media have added to the skills of cyber criminals. The best practice to combat these cybersecurity threats is to be aware of different threat types and be prepared with effective cybersecurity strategies.

Here is a detailed list of cybersecurity threats that businesses should be aware of:

• Cloud Vulnerability: Cloud vulnerability is and will continue to be one of the biggest cybersecurity challenges faced by business organizations. The major reason behind this is the changing business scenario as organizations have increasing number of remote employees. The employees need to access business data from different locations in order to be efficient and productive. Thus, organizations are leveraging cloud applications and storing sensitive business data on cloud storage. Some of these cloud vulnerability attacks include data breach, mis-configuration, insecure interfaces and APIs, account hijacking, malicious insider threats, and DDoS attacks.
• AI-Enhanced Cyberthreats: AI and machine learning have found extensive applications in all fields including marketing, manufacturing, security, supply chain management, business mainstream, etc. Cyber criminals are also exploiting AI to launch sophisticated cybersecurity attacks such as AI Fuzzing and Machine Learning Poisoning.
• AI Fuzzing: Fuzzing refers to usually automated process of finding hackable software bugs by randomly feeding different permutations of data into a target program until one of those permutations reveals vulnerability. AI fuzzing integrates AI with traditional fuzzing techniques to create a tool that detects system vulnerabilities, start, automate and accelerate zero-day attacks.
• Machine Learning Poisoning: The cyber criminals target a machine learning model and inject malicious software in it. This makes the system (operating the model) vulnerable to cyber security attacks. As machine learning models feed on data sourced from surveys or social media, cyber criminals exploit user-generated information such assatisfaction ratings, purchasing histories, or web traffic by using malicious samples, introducing backdoors or Trojans for poisoning training sets and compromising the model.
• Smart Contract Hacking: Smart contracts are specially designed programs that contain self-executing codes for creating rules and processes that build blockchain-based applications. Since this is a new concept, researchers are still finding bugs in these programs. Cyber criminals exploit these vulnerabilities and target the programs for hacking into applications. this poses as a new cybersecurity threat for businesses.
• Deepfake: It is a fake video or audio created by modes such as swapping a famous person’s face in videos or altering the audio track of a video to spread fake news. The technology is AI-based and is being used extensively by cyber criminals to cause disruption across various industry segments such as financial market, media, entertainment and politics. In business world, these fake videos may be used to impersonate CEOs to spread fake news about a business.
