Smishing America
You know, fishing is America’s favorite pastime. Where is that said? We don’t know. Most people argue that it’s baseball, but we and you know it’s fishing. Baseball is the one sport where you wait for something big to happen, and if you have luck like ours, things happen when you’re not looking at the game. To be clear, we don’t dislike baseball, we dislike watching paint dry.
Fishing for a Message
So, picture this, you’re on a boat out on the lake. You have your favorite lure, a cooler full of cold ones, it’s a nice sunny cool day, and you have the afternoon at your disposal. After finding a spot to anchor, casting your reel, setting up your fishing pole, and like a creep stalking their crush, you begin the waiting process. A bing sound goes off startling you and causing the boat to shake a little. Crap, you forgot to silence your phone, now you may have to wait a little longer until something bites.
Annoyed, you check to see the notification and find that a message came from a number that you’re not familiar with. You think to yourself, “Strange, but it’s 2024 where everyone is texting everyone and no one knows anyone.” Surprisingly, the text is about a potential job opportunity that your resume hints you’ll be perfect for.
Thinking, “I’m not in need of a job at the moment, but it couldn’t hurt to see what they have to offer.” Hell, by today’s standard, job hopping is the new trend, and being loyal don’t pay fart. Excited after reading and seeing a preview of all they have to offer, you race to contact the unknown sender/potential hiring manager.
After exchanging messages giving all the information needed to begin the hiring process and being annoyed with the fishing line being tugged because it’s causing you to juggle your focus, you begin to get the sense that the fish being caught was you.

Smish, A Different kind of Phish.
You have been phished before; we all have. Those, “I’m a prince and I need you to hide money”, and “You won a million dollars in a sweepstake you have no recollection entering” messages popping up in your email inbox are called “phishing”. This is done with the intent to get you to hand over personal information unwittingly. However, things in the cybersecurity landscape have taken a turn from pinging your email to pinging your phone.
What is Smishing?
This is the new form of phishing carried out over mobile text messaging. Bad actors use text messages to trick victims into revealing sensitive information, clicking on malicious links, or downloading harmful software. This is a shame because if they offer puppies at a discount, all you have to do is click on the link to start your order. We here at Scriptingthewhy might be in trouble. We love puppies and if you don’t or animals in general, we’re judging you and you’re a monster.
How Smishing Works
Smishing attacks typically follow a structured approach:
Target Selection: Cybercriminals choose their targets, which can be random or based on data from previous breaches.
Crafting the Message: Attackers create a deceptive message designed to evoke emotions such as urgency, fear, or curiosity. These messages often appear to be from trusted sources like banks or government agencies.
Message Delivery: Using SMS gateways or spoofing tools, the attacker sends the smishing message to the selected targets.
Interaction: The victim receives the message and is prompted to take action, such as clicking a link or providing personal information.
Types of Smishing Attacks
Smishing attacks can take various forms, including:
Malware Distribution: The smishing message contains a link that, when clicked, downloads malware onto the victim’s device. This malware can steal data, monitor activities, or even take control of the device.
Credential Harvesting: The message directs the victim to a fake website that mimics a legitimate one, prompting them to enter login credentials or other sensitive information.
Financial Fraud: Attackers pose as financial institutions, asking victims to verify account details or make urgent payments.
Real-World Examples
Banking Scams: Victims receive messages claiming to be from their bank, warning of suspicious activity and urging them to click a link to secure their account.
Package Delivery Scams: Messages inform victims of a pending package delivery and ask them to click a link to confirm or reschedule.
Government Impersonation: Attackers pose as government agencies, threatening legal action unless the victim provides personal information or makes a payment.

How to Identify and Prevent Smishing Attacks
Identifying Smishing Attacks:
Unexpected Messages: Be wary of unsolicited messages, especially those requesting personal information or urgent action.
Suspicious Links: Avoid clicking on links in text messages from unknown or unverified sources.
Spelling and Grammar: Poorly written messages with spelling and grammar errors can be a red flag.
Preventing Smishing Attacks:
Educate Yourself and Others: Awareness is the first line of defense. Educate yourself and others about the risks and signs of smishing.
Verify the Source: If you receive a suspicious message, verify its authenticity by contacting the supposed sender through official channels.
Use Security Software: Install and maintain security software on your mobile devices to detect and block malicious activities.
Report Smishing: Report smishing attempts to your mobile carrier and relevant authorities to help combat this threat.
Conclusion
Smishing represents a growing threat in the realm of cybersecurity, exploiting the trust and ubiquity of mobile text messaging. Yes, not performing a quick research on who is contacting you, could lead to you losing money or worse, heartache.
By understanding how smishing works and taking proactive measures to identify and prevent attacks, individuals, and organizations can better protect themselves against this insidious form of cybercrime.

Understanding Zero Trust: A comprehensive guide (sort of)
The landscape of cybersecurity doesn’t show any signs of slowing down, this means we have to grow along with it. The concept of Zero Trust has emerged as a critical framework for protecting sensitive data and systems. And before you ask which data and systems are important, it’s all of them.
Now, unlike security models of the past that rely on perimeter defenses, Zero Trust operates on the principle that threats can come from outside and inside the network. This gives credence to “The call is coming from inside the house.” That being said, we’ll be looking at the principles, implementation strategies, and benefits of Zero Trust. By the end of this post, you’ll be able to completely trust no one.
What is Trust?
Before we going understanding what zero trust is, first we have to understand what trust is. For most people, trust is something earned and not given. We as humans tend to make it clear that once someone has our trust, they pretty much hold the keys to the kingdom.
Trust is, and this is according to Google – is a feeling or expectation that can emerge from interactions with a person, group, or organization. Looking at any military or team sports activity we ultimately look for qualities in a person for us to say, “I feel like I can trust them.”
We mean, we wouldn’t want someone watching our back if we didn’t believe they had our best intentions at heart. So, yeah, trust is a big thing for everyone. Google also said trust can be built through patterns of behavior, discipline, simple rules, and collective habits.
We understand for many working right now internally, this must be a warzone for you as when you’re at work, the common course of action is to not trust coworkers, your boss, or anyone in human resources.
What is Zero Trust?
Now that we know what trust is, zero trust is a security model that assumes no implicit trust is granted to any user, device, or application, regardless of their location within or outside the network.
Every access request is thoroughly verified before granting access to resources. This approach minimizes the risk of unauthorized access and data breaches… well, at least try to.
Money is a good motivator to get people to venture into the dark side. Paying your workers a decent wage is what we’re getting at. Remember; if you pay well, you won’t pay hell.
Historical Context
To understand the significance of Zero Trust, it’s essential to look at the evolution of cybersecurity models. Traditional security models relied heavily on perimeter defenses, such as firewalls and intrusion detection systems (IDS).
These models operated on the assumption that threats primarily originated from outside the network. However, with the rise of insider threats, advanced persistent threats (APTs), and the increasing complexity of IT environments, the limitations of perimeter-based security became evident.
Always keep in mind, that humans are the oldest form of computers with the “choice” to upgrade && update however, emotions tend to get the best of us.
The Shift to Zero Trust
The shift to Zero Trust represents a fundamental change in how organizations approach security. Instead of assuming that everything inside the network is safe, Zero Trust assumes that threats can come from anywhere.
A good way to picture this is to imagine yourself as the little girl “Newt” in the movie “Aliens” and the army guys inform you “Everything is going to be all right.” You know they come out at night…mostly.
This shift is driven by several factors, including the rise of remote work, cloud computing, and the increasing sophistication of cyberattacks.
Core Principles of Zero Trust
Verify Explicitly: Always authenticate and authorize based on all available data points, including user identity, location, device health, and more.
Use Least Privilege Access: Limit user access with just-in-time and just-enough-access (JIT/JEA), risk-based adaptive policies, and data protection to minimize exposure.
Assume Breach: Design systems with the assumption that a breach has already occurred. This mindset encourages continuous monitoring, logging, and response to potential threats.
Principle 1: Verify Explicitly
The principle of explicit verification is at the heart of Zero Trust. This means that every access request is thoroughly vetted before granting access. This involves multiple layers of authentication and authorization, including:
Multi-Factor Authentication (MFA): Requiring multiple forms of verification, such as a password and a fingerprint, to ensure the user’s identity.
Contextual Authentication: Considering factors such as the user’s location, device, and behavior to determine the legitimacy of the access request.
Continuous Authentication: Continuously verifying the user’s identity throughout the session, rather than just at the point of login.
Principle 2: Use Least Privilege Access
The principle of least privilege access ensures that users only have the minimum level of access necessary to perform their tasks. This minimizes the potential damage that can be caused by compromised accounts. Key strategies include:
Role-Based Access Control (RBAC): Assigning permissions based on the user’s role within the organization.
Just-In-Time (JIT) Access: Granting temporary access to resources only when needed.
Just-Enough-Access (JEA): Providing only the necessary permissions required for a specific task.
Principle 3: Assume Breach
Assuming breach means designing systems with the expectation that a breach will occur. This proactive approach involves:
Segmentation: Dividing the network into smaller segments to contain potential breaches.
Monitoring and Logging: Continuously monitoring network activity and maintaining detailed logs to detect and respond to suspicious behavior.
Incident Response: Developing and regularly updating incident response plans to quickly address breaches when they occur.

Implementing Zero Trust
Identity and Access Management (IAM): Implement strong authentication mechanisms such as multi-factor authentication (MFA) and single sign-on (SSO) to ensure that only authorized users can access resources.
Network Segmentation: Divide the network into smaller, isolated segments to limit lateral movement of attackers. Use micro-segmentation to enforce granular access controls.
Endpoint Security: Ensure that all devices accessing the network are secure and compliant with security policies. Use endpoint detection and response (EDR) solutions to monitor and mitigate threats.
Continuous Monitoring and Analytics: Implement real-time monitoring and analytics to detect and respond to anomalies and potential threats. Use security information and event management (SIEM) systems to aggregate and analyze security data.
Data Protection: Encrypt sensitive data both at rest and in transit. Implement data loss prevention (DLP) solutions to prevent unauthorized data exfiltration.
Identity and Access Management (IAM)
IAM is a critical component of Zero Trust. It involves managing user identities and controlling access to resources. Key elements include:
User Provisioning and Deprovisioning: Ensuring that users are granted access only to the resources they need and that access is promptly revoked when no longer required.
Authentication: Implementing strong authentication mechanisms, such as MFA and SSO, to verify user identities.
Authorization: Defining and enforcing access policies based on user roles and responsibilities.
Network Segmentation
Network segmentation involves dividing the network into smaller, isolated segments to limit the lateral movement of attackers. This can be achieved through:
Micro-Segmentation: Creating granular segments within the network to enforce strict access controls.
Virtual Local Area Networks (VLANs): Using VLANs to separate different types of traffic and enforce security policies.
Software-Defined Networking (SDN): Leveraging SDN to dynamically manage and enforce network segmentation.
Endpoint Security
Endpoint security ensures that all devices accessing the network are secure and compliant with security policies. Key strategies include:
Endpoint Detection and Response (EDR): Using EDR solutions to monitor and respond to threats on endpoints.
Device Compliance: Enforcing security policies on devices, such as requiring encryption and regular updates.
Mobile Device Management (MDM): Managing and securing mobile devices that access the network.
Continuous Monitoring and Analytics
Continuous monitoring and analytics are essential for detecting and responding to threats in real-time. Key components include:
Security Information and Event Management (SIEM): Aggregating and analyzing security data from various sources to detect anomalies and potential threats.
User and Entity Behavior Analytics (UEBA): Using machine learning and analytics to identify unusual behavior that may indicate a threat.
Threat Intelligence: Leveraging threat intelligence to stay informed about emerging threats and vulnerabilities.
Data Protection
Data protection involves securing sensitive data both at rest and in transit. Key strategies include:
Encryption: Encrypting data to protect it from unauthorized access.
Data Loss Prevention (DLP): Implementing DLP solutions to prevent unauthorized data exfiltration.
Access Controls: Enforcing strict access controls to ensure that only authorized users can access sensitive data.

Fewer Darkrooms
Cybersecurity is a field that often conjures images of dark rooms filled with screens, and lines of code scrolling endlessly as intrepid defenders fend off digital attacks. However, this Hollywood portrayal is far from complete. Cybersecurity extends well beyond the confines of computer systems and into the realm of human psychology, organizational behavior, and even physical security.
At its core, cybersecurity is about protecting valuable assets, which are not always digital. Information, whether stored on a server or printed on paper, is an asset. The people who use and manage that information are assets, too. Cybersecurity professionals must consider a wide array of potential vulnerabilities, from the strength of passwords to the security of the building where the servers are located.
Shoulder surfing sometimes is a hacker’s best friend. Photo by cottonbro studio, please support by following @pexel.com
Social engineering is a prime example of a non-digital threat. It involves manipulating individuals into divulging confidential information or performing actions that compromise security. This could be as simple as a phone call from someone pretending to be a colleague asking for a password. It’s not about cracking codes; it’s about cracking people.
Physical security is another critical aspect. A locked door or a security guard might be all that stands between a secure network and an intruder with a flash drive. Cybersecurity experts must work closely with facilities management to ensure that the physical environment is as secure as the digital one.
Then there’s the human element. Training and awareness are vital. Employees need to understand the importance of security protocols and how to recognize potential threats. Cybersecurity is as much about creating a culture of vigilance as it is about installing the latest firewall.
In constructing a cybersecurity strategy, the first step is to assess the value of the assets and determine the potential risks. From there, it’s a matter of figuring out how to protect those assets and how to respond if they are compromised. This involves a combination of technological solutions, physical security measures, and educational initiatives.
Sometimes protecting the network is too much for one to handle. Photo by cottonbro studio, please support by following @pexel.com
The reality is that cybersecurity is a complex, multifaceted challenge that requires a holistic approach. It’s not just about technology; it’s about people, processes, and the physical world. It’s a field that is constantly evolving, as cybercriminals develop new tactics and cybersecurity professionals adapt to counter them.
So the next time you picture a cybersecurity professional, don’t just imagine them in front of a computer. Imagine them assessing the value of assets, collaborating with colleagues across different departments, and educating staff on security best practices. Cybersecurity is a dynamic and exciting field, and it’s about much more than just computers. It’s about protecting a way of life in the digital age.
