Tunneling Through History
DNS tunneling is a cunning cyberattack method that leverages the internet’s backbone, the Domain Name System (DNS). DNS acts as the “phonebook of the internet,” translating user-friendly domain names into machine-readable IP addresses. However, its vital role and inherent trust make it a prime target for attackers.
The idea of DNS tunneling emerged in discussions as early as 1998, with the first major instances documented in the early 2000s. It works by cleverly encoding data from other protocols within seemingly ordinary DNS requests and responses. This creates a hidden communication channel that bypasses conventional security measures like firewalls, making it a stealthy tactic.

The impact of DNS tunneling on individuals and organizations today is severe. Attackers exploit this method to steal sensitive data, establish covert command-and-control channels for malware, and even bypass firewalls altogether. Recent campaigns have shown an expansion in the use of DNS tunneling, including tracking victim behavior and scanning network infrastructures.
Defending against DNS tunneling requires a multi-layered approach. Continuous monitoring of DNS traffic is crucial to identify anomalies. Additionally, implementing DNS Security Extensions (DNSSEC) adds a vital layer of security to the DNS protocol itself. Firewalls should be configured to restrict outgoing DNS traffic to authorized DNS servers only. Finally, staying up-to-date with regular patching and updates helps address vulnerabilities that attackers might exploit.

However, it’s important to remember that DNS tunneling presents a unique challenge for defenders. Because DNS traffic itself is inherently full of varied requests and responses, distinguishing legitimate activity from malicious tunneling can be difficult. This is why a combination of the aforementioned strategies is essential to create a robust defense.
By staying vigilant and employing these preventive measures, individuals and organizations can significantly improve their protection against the threats posed by DNS tunneling.

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.
