What Is Clickjacking?

Clickjacking is a type of cyberattack that deceives users into believing they're clicking on one thing while they're actually clicking on something else. Also known as UI (User Interface) Redressing where users believe they are using the standard UI of a web page, but actually, that is a concealed UI in control. The hidden UI takes a different behavior when consumers click something they think is safe.

This attack's final objective is to lure victims into disclosing their PII (Personally Identifiable Information) or even infect their devices with malware. The real objectives can be almost anything that can be done through web pages. This includes blackhat hacker behaviors such as installing malware and stealing credentials or even conducting a ransomware attack on infected devices. Benign activities like raising click counts to increase advertisement income on sites, getting likes and views on Facebook and YouTube are also possible.

How will you prevent your website’s users from getting click jacked?


Web developers can use one of these two methods: -

  1. Client-side techniques include Frame Busting, which is the most prevalent one. Such techniques can be useful in some situations, but they are not recommended because they can be readily circumvented.
  2. X-Frame-Options is the most often used server-side approach. Security experts advise using server-side approaches to combat clickjacking.

So, how does anyone get click jacked?
First, any attacker produces a visually appealing website that offers visitors a free trip to any overseas country. In the background, the attacker is actually checking if the users are signed into the banking site via cookies stored in the browser. If so, the attacker opens the page that allows for fund transfers, inserting the attacker's bank data into the form using query parameters. The bank transfer page appears in an invisible iframe above the free trip page, with the "Confirm Transfer" button perfectly positioned over the user-visible "Receive Free Trip" button. The user arrives at the website and selects the "Book My Free Trip" option. In actuality, the user is clicking on the "Confirm Transfer" button on the unseen iframe. The funds are sent to the attacker. The user is taken to a website where they might learn more about the free trip (not knowing about what happened actually in the background).

How to check whether your website is vulnerable to clickjacking?
Create an HTML page and try to incorporate a sensitive page from your website in an iframe to see if your site is vulnerable to clickjacking. This is common behavior in a clickjacking assault, it's critical to run the test code on a different web server.

<html>
<head>
<title>Clickjacking Cyberattack Vulnerability Test</title>
</head>
<body>
<p><b>Website is Vulnerable to Clickjacking Cyberattack.!<b></p>
<iframe src="<entire website link>" width="300" height="300"></iframe>
</body>
</html>

In a browser, open the HTML page and assess it as follows:

  1. The content of your sensitive page is vulnerable to clickjacking if the words “Website is Vulnerable to Clickjacking Cyberattack.!” appear underneath it.
  2. The page is not vulnerable to the basic kind of clickjacking if you simply see the words “Website is Vulnerable to Clickjacking Cyberattack.!” and do not view the content of your sensitive page.
    Additional testing is required to determine which anti-clickjacking measures are employed on the page and whether they may be circumvented by attackers.

How web developers could use the X-Frame-Options HTTP Header?
It allows an application to declare whether frame usage is merely banned, as indicated by the DENY value, or whether frame use is permitted, as shown by the SAMEORIGIN and ALLOW-FROM values. This header option is supported by most current browsers. X-Frame-Options your web developers can use:
X-Frame-Options: DENY
X-Frame-Options: SAMEORIGIN
X-Frame-Options: ALLOW-FROM <entire website link>

The ultimate solution for addressing clickjacking vulnerability
CSP (Content Security Policy) allows the developers to disable frame usage entirely or define where it is permitted. CSP isn't supported by all browsers, and a few browser plugins and add-ons may be able to get around it. Browsers are expected to favor CSP's directives if both the X-Frame-Options header and CSP frame-ancestors are utilized, however not all do. Defense-in-depth is a smart practice, and there's nothing wrong with utilizing all three defenses on your websites because none of them are flawless. Web application developers can utilize these CSP frame-ancestors setting- to prevent clickjacking:
Content-Security-Policy: frame-ancestors 'none'
Content-Security-Policy: frame-ancestors 'self'
Content-Security-Policy: frame-ancestors <website link>

What Are Deepfakes And Why Are They Dangerous?

Deepfake is a type of artificial intelligence created by combining the phrases deep learning and fake that facilitates in developing videos that have been fabricated via using deep learning techniques. It is a subset of AI that refers to algorithms that can learn and make intelligent judgments without human intervention. A deep-learning system can create convincing impersonations by examining images and videos of a target person from various perspectives and then copying their behavior and voice patterns. Once a prototype fake has been created, GANs (Generative Adversarial Networks) are used to make it more credible. The GANs method aims to find faults in the system and make adjustments to fix them.

How can you stay away from deepfake videos?

  1. Deepfake videos are much simpler to spot than deepfake photographs. And you may accomplish so with the assistance of two factors. When a deepfake video of a person is created, for example, there is little difference between the person and the backdrop. However, you may spot a false video if the attention is solely on the face in the video and the surrounding is purposefully obscured.
  2. Deepfake can be easily avoided by restricting personal images on social media and avoiding close-up photos of your face as much as possible.
  3. Advanced artificial intelligence algorithms are under development which can swiftly identify deepfake videos thereby preventing people from falling prey to fake news and fake films.

When and where did deepfake start?

Deep Fake was a user on Reddit in 2017 who began employing face modification technology for pornography. It was from here that the term Deepfake was coined, and videos like this were known as Deepfake Videos. 

Deepfake as a boon to technology

MyHeritage, a software program, has been in the headlines for transforming any image into a 10-second movie. With this app, you may also breathe new life into old images using this program. With the use of this program, images of prominent personalities from past were transformed into movies. And these films show that if Artificial Intelligence is applied correctly, this approach may be beneficial to humans.

Deepfake as a threat to humanity

A.  Deepfakes were used to subvert democracy in the United States 

Facebook decided to prohibit the use of deep fakes after fake videos of politicians began spreading on social media. They allowed a few loopholes, such as the ability to keep sarcastic films and photos, but distinguishing between satire and agenda-driven content is difficult.

B.  Deepfakes began to be exploited by internet predators 

People began leveraging the ability to substitute anyone's face in an image or video to make pornographic content without their consent. As the deep fake technology allows them to do so by replacing face and expressions; all cybercriminals need is a profile photograph on social media to produce fake material to produce fake videos.

C.  Deepfake to tarnishing reputation of individuals 

A Pennsylvania mom, for example, was prosecuted for harassing cheerleaders at her daughter's school by employing deep fakes. The mother used manipulated recordings to carry out a cyberbullying campaign against girls she viewed as competitors to her daughter.

Deepfakes still continues pushing the digital media envelope where researchers suggest using NFTs (Non-Fungible Tokens) is the most effective strategy to combat deep fake. But NFTs, on the other hand, are still far away from being the standard on blockchains like Ethereum.

Wi-Fi For Smart Buildings

The capacity to tap into enormous volumes of data to enable real-time, intelligent decision-making is of crucial importance for any smart building. Builders need a dependable and adaptable communications infrastructure that can serve both current and future use cases. Security is paramount to all digital technologies as traditional WiFi deployment architecture has become vulnerable. Builders and contractors must consider addressing these constraints to improve the experience of residents using WiFi in smart buildings.

Constraints over deploying WiFi in smart buildings: -

  1. Leave no blind-spot - Someone might require network access in lobbies, meeting rooms, and other common areas. Physical security management teams increasingly require comprehensive coverage. Wireless IoT sensors could be deployed at elevator shafts, maintenance rooms, roofs, & parking garages. 
  2. Cabling and installation - Twisted pair cabling improves the WiFi 6 and 6E performance. Category 6A cable should be installed as PoE (Power over Ethernet) devices get more complex, and frequently require more power to function. Ensure safe delivery of high electric watt supply to WiFi APs (Access Points), UHD (Ultra-HD) security cameras, IoT sensors, and PoEs.
  3. Antenna and Radar - Antenna types such as yagi, panel, and parabolic are better alternatives for coverage and performance in regions with concrete or plaster walls or huge metal machinery. The interior-exterior environment such as office spaces, atriums, parking garages, maintenance, or engineering floors often decides the type of antenna to be deployed. WiFi access points with built-in antennas must be created for conventional office area deployments. This will bypass the physical obstacles such as drywall, cubicle barriers, office-grade doors, and glass panes.
  4. Network subnetting - Strict WiFi access controls must be implemented by employing micro-segmentation to mitigate malware outbreaks and service disruptions. LPWAN (Low-Power-Wide-Area Networks) provides ease of deployment, and ultra-low power consumption is required to scale with low-computing, battery-operated IoT sensor devices. LPWAN system requires a single base station to link thousands of scattered endpoints across the building utilizing the basic star topology. LPWAN utilizes sub-GHz frequencies. This helps to avoid excessive interference from old wireless systems functioning in the building at 2.4 GHz range. This ensures long-term network dependability. At the end of the day, the robustness and reliability of your WiFi systems will determine whether your smart building architecture succeeds or fails.

The range of smart building applications is enormous, and it's developing all the time. As a result, in order to take advantage of everything that this transition has to offer, both existing broadband networks and future low-power IoT connections will need to coexist in the wireless architecture.

WiFi deployment in smart buildings helps in: -

  1. Occupancy and damage detection - Integrating different systems over WiFi in smart buildings can help in regulation of safe distance measure and sanitation operations. It can also detect faults in time and prevent avoidable maintenance and energy expenditures.
  2. HVAC and access control systems - Smart building systems can reduce utility expenditures, carbon emissions and increase tenant satisfaction by installing AI-enabled HVAC (Heating Ventilation and Air Conditioning) systems. Smoke detectors, window/door sensors, intrusion, and fire alarm systems can also integrate with HVAC and the system can identify irregularities proactively to resolve them early on.
  3. Monitoring of the environment & consumables - Smart building systems can monitor IAQ (Indoor Air Quality) conditions to enhance the health, comfort, and well-being of building occupants and to lower the risk of respiratory complaints. The WiFi enabled system can also monitor in real-time how much hand sanitizer, soap, paper towels, and toilet paper is being used in the building. To guarantee timely refills and the health and safety of tenants, receive notifications when products are running short.

Centex Technologies provide IT and networking solutions for establishments. For more information on deployment of WiFi for smart buildings, call Centex Technologies at (972) 375 - 9654.

Multi-Cloud For Organizations

What Is Multi-Cloud?

Multi-cloud means utilization of two or more public cloud service providers to serve the needs of IT services and infrastructure of an organization. The organizations may choose the best services from different cloud service providers based on multiple factors such as cost, technical requirements, geographic availability, security, etc. A simple example is where an organization uses one cloud service provider for development/test, one for disaster recovery, and another to process business analytics data.

Alternatively, an organization may leverage multiple public clouds in combination with private cloud deployments and traditional on-premise infrastructure.

What Is The Purpose Of Multi-Cloud Approach?

Here are the reasons why an organization should adopt a multi-cloud approach:

  • Overcoming Data Gravity: Data gravity refers to the idea that it is difficult to move or migrate large data sets and thus, it is important to store the data in proximity with applications and services used to analyze them. Using a cloud-attached storage solution that connects to multiple clouds simultaneously can help in overcoming data gravity. Efficient solutions help in reducing latency by hosting data in close proximity to cloud data centers.
  • Optimizing Work Loads: Every cloud service provider offers its own set of physical infrastructure components and application services, while releasing new features on a regular basis. Thus, no cloud service provider can provide cost-optimized services. By adopting multi-cloud approach, organizations have an option to select most suitable provider for every workload leading to enhanced application performance.
  • Avoiding Vendor Lock-In: Vendor lock-in refers to a situation where it becomes difficult for an organization to transfer its business away from one service provider to another service provider or back to on-premise infrastructure. However, by adopting multi-cloud approach, an organization has the flexibility to transfer its application to any cloud service provider which allows the organization to take advantage of new technologies.
  • Additional Benefits: Multi-cloud approach serves the purpose of enhancing disaster recovery capabilities, meeting regulatory compliance, curbing shadow IT, elevating application performance, etc.

How To Monitor Multi-Cloud Strategy?

  • Use monitoring tools designed specifically for multi-cloud environment.
  • Leverage a configuration management database.
  • Adopt a mechanism that can sense, analyze, adapt, and visualize to help admins resolve outages.
  • Use monitoring tools that support automation.

All You Need To Know About Zero-Day Attacks

Zero-Day also mentioned as 0-Day indicates that the vendor or developer has very recently got to know about that flaw. Since the hackers have exploited the flaw before developers can discover & patch it, the Vendor has Zero Days to fix it. Some meaningful terms to understand 0-Day better:

  1. 0-Day Vulnerability is discovered by hackers before the developers and hence they cannot be patched. However, developers can implement and notify workaround techniques to temporarily address it.
  2. 0-Day Exploits are the TTPs (Tactics-Techniques-Procedures) used by hackers to attack IT infrastructure.
  3. 0-Day Attack involves using 0-Day Exploit targetting 0-Day Vulnerability inflicting damage to IT resources.

Cybercriminals and hacktivists with malicious intentions such as espionage and theft, financial gains, cyber warfare, service disruption, and likewise usually carry out such 0-Day attacks. Its victims could be anyone and everyone across the globe ranging from an individual to an organization and even a nation-state. Operating systems and software applications, hardware and firmware, IoT (Internet of Things) devices, household appliances, automobiles are the usual targets. Attacks carried out against potentially valuable targets such as MNCs (Multi-National Companies), government and intelligence agencies, or VVIPs (Very Very Important Persons) are targeted 0-Day attacks. Vulnerable systems-servers or applications and hardware are the usual victims of non-targeted 0-Day attacks. Sometimes the LEAs (Law Enforcement Agencies) are unable to comprehend the collateral damage caused by attackers.

Zero-Day exploits are considered the ultimate cyber weapon to inflict heavy and often irreparable damage. Poor cybersecurity hygiene, ignorance & lethargy of security professionals, inadequate budgets, skill gaps in the availability of skilled and qualified cybersecurity workforce are some of the reasons behind getting victimized by a 0-Day vulnerability. When victims get to know about a 0-Day vulnerability in their environment, it is often too late to mitigate them. The course of action is to either accept the risk and threats of attack(s) or shut down the crucial components/facilities of their operations and services.

So, how would you try to protect yourself, as much as possible, from getting affected by the 0-Day exploits?

Prevention is however almost impossible for 0-Day vulnerabilities but detection and mitigation strategies are still relevant here. 4 proactive and protective best practices might help you and your firm stay resilient against most 0-Day attacks: -

  1. Educate and be aware against social engineering: Employees and business partners need to understand the bigger picture of business risk. Everyone must take moral ownership to keep the business services and daily operations safe & secure in their individual capacities. User awareness training must be conducted to prevent the staff from getting targeted by social engineering attacks. 
  2. Implement 2FA / MFA with biometrics: Deploy 2FA (2-Factor Authentication) and MFA (Multi-Factor Authentication) along with biometric locks will keep unauthorized users or hackers at bay. It is advised to periodically change the credentials used to access the various digital resources across your organization. Modify and update the vendor-supplied default security configuration to customize as per the business requirements. 
  3. Strict ACL (Access Control List): Be vigilant when you grant any user the read and/or write access or elevate their privileges from user to admin and likewise. Grant or assign the privileges or access on a Need-to-Know basis only.! Deploying an appropriate IAM (Identity and Access Management) plan prevents accidental information modification from unauthorized employees. It also limits the scope of access for hackers having stolen the employees’ credentials. Implement a systematic de-provisioning process for employees leaving the company so their access to the IT systems, applications, and data is curtailed. Revoking the access rights of someone who has left the organization is very much a crucial security responsibility that must be completed on the LWD (Last Working Day) & not get delayed. 
  4. Depth-in-defense & defense-in-depth approches: Maintaining your organization’s credibility in the market is very important. Comply with various regulatory standards & frameworks to protect highly sensitive business information. The in-house SOC (Security Operations Center) team can monitor the real-time activities of users, services, and applications in your IT environment. Alternatively, to facilitate inadequate budgets & lack of resources, you can hire an MSSP (Managed Security Service Provider). They help you to outsource your security logging & monitoring requirements. They prevent, detect, analyze, & mitigate security risks, threats, vulnerabilities, & incidents for your business. Protect your data & devices with various security solutions such as NGAVs (Next-Gen Anti-Virus), DLP (Data Loss Prevention), XDR (Extended Detection and Response), Honeypot, and likewise. Training and securing your users and employees would give hackers a hard time targeting your IT infrastructure with 0-Day vulnerabilities.

BEC: Business Email Compromise Attacks Are On The Rise

The BEC (Business Email Compromise) attack is a scam that usually targets corporates that conduct wire transfers to overseas suppliers. They target official email accounts of executives and high-level employees working in administration or finance departments. Such email addresses, involved with conducting wire transfer payments are either spoofed or compromised through keyloggers or phishing attacks. Corporations lose hundreds of thousands of their revenue every year via these fraudulent transfers.

Attackers in the BEC, also known as the Man-in-the-Email scam, rely on social engineering tactics. They trick the employees and executives working in non-tech roles. They usually impersonate employees from the board of directors/management, or executives who are authorized to do wire transfers. Additionally, fraudsters also research and closely monitor their potential target victims, their organizational movements, and likewise.

Security Professionals in any organization usually encounter these 5 types of BEC scams:

  1. Fraud invoice: Firms with overseas suppliers are targeted wherein attackers impersonate suppliers requesting fund transfers for payments to account(s) owned by fraudsters.
  2. Executive fraud: Attackers impersonating executives send the email(s) to finance, administration, or procurement department employees requesting them to transfer money to account(s) that the hackers’ control.
  3. Account compromise: Executive(s) or employees’ email account(s) are hacked to request invoice payments to vendors or clients listed in their email contacts.
  4. Attorney impersonation: Attackers impersonate any person from the legal team or from any legal firm in charge of important and urgent matters regarding your organization.
  5. PII theft: PII (Personally Identifiable Information) of employees and tax-related statements in possession of the HR department are harvested to carry out future targeted attacks on potential individual victims.

GreatHorn, a cloud email security provider, released a BEC landscape report in 2021 that is based on information provided by 270 IT and cybersecurity professionals. 30% of them confirmed receiving 50% of malicious links in emails while a similar number of participants from the BFSI sector revealed being a victim of spear-phishing attacks. 35% of organizations disclosed that BEC attacks account for 50%+ of their incidents while a similar percentage of firms encounter spear-phishing emails on a weekly basis. Half of the professionals have dealt with a security incident in the past 12 months where every 1 out of 4 companies received at least 76% of the malware they detected via email. Usually, these email(s) do not contain any malicious links or attachments, hence they easily evade traditional as well as advanced security solutions deployed. BEC attacks are becoming more expensive than ransomware and are usually unbeatable.

 How would you protect yourself from getting tricked by these cyber fraudsters? 

  1. Check the source of email including the domain name from where it has been sent.
  2. Be alert to see anything suspicious regarding payment requests over emails.
  3. Protect email systems with advanced software capable of tracking spam and filtering out emails.
  4. Don’t make presumptions over the email, always confirm the wire transfer requests with the sender over a phone call or a video call.
  5. When in doubt, contact cybersecurity teams in your organizations as you encounter such emails in your inbox.
  6. By training the employee staff, executives, partners, clients, and customers in end-user security awareness. This can help detect and prevent being a victim of BEC attacks.
