Top Malware Delivery Tactics to Watch Out for in 2023

As we continue through 2023, the landscape of cybersecurity threats continues to evolve, with malware delivery tactics becoming increasingly sophisticated and challenging to detect. Cybersecurity experts predict that cybercriminals will continue to refine their methods and develop new ones to evade traditional security measures. In this blog post, we will explore some of the top malware delivery tactics to be aware of in 2023 and provide insights on how to protect your systems from these evolving threats.

1. Fileless Malware: The Silent Threat

Fileless malware is a rising concern as it becomes more difficult to detect using traditional antivirus software. Unlike conventional malware that relies on files or executables, fileless malware uses legitimate system tools and processes, commonly referred to as living off the land, to execute its payload. This stealthy approach makes it highly challenging to identify and block.

Fileless malware can infiltrate systems through various means, including phishing emails, malicious websites, and watering hole attacks. Once inside a system, it can steal sensitive data and propagate the infection across the network.

2. Social Engineering: Exploiting Human Vulnerabilities

Social engineering attacks continue to evolve in sophistication, relying on psychological manipulation to trick users into downloading and installing malware. Attackers employ methods like phishing emails, social media messages, unsolicited text messages, and phone calls to exploit human vulnerabilities, such as curiosity, fear, and trust.

Phishing emails, in particular, are a common social engineering tactic, where attackers send seemingly legitimate emails with malicious links or attachments that, when clicked, download malware onto the victim’s computer.

3. Targeted Attacks (APTs): A Relentless Pursuit

Targeted attacks, also known as advanced persistent threats (APTs), are meticulously crafted and designed to evade conventional security measures. APTs involve multiple stages and can take weeks or months to execute. These attacks primarily target high-value entities like government agencies, financial institutions, and large corporations.

APTs can be delivered through spear-phishing emails, watering hole attacks, and supply chain attacks. Once inside a system, the malware can remain undetected for an extended period, allowing cybercriminals to steal sensitive data, such as intellectual property and confidential information.

4. Malvertising: Malware in Plain Sight

Malvertising, a growing threat, leverages legitimate advertising networks to deliver malware. Attackers embed malicious code within seemingly legitimate ads, and when users click on these ads, the malware is downloaded and executed on their systems. This tactic enables attackers to target a large number of users by placing their malicious ads on popular websites.

5. OneNote Files: An Undetected Delivery Method

Attackers are now exploiting OneNote files to deliver malware because they are typically not scanned by antivirus software. Since OneNote files are commonly used for notetaking and sharing information, attackers find it easier to deliver their payloads undetected. Once the malware infects a system, it can steal sensitive data and propagate the infection throughout the network.

6. Archives: Concealing Malware in Password-Protected Files

Attackers are also using archives, such as ZIP and RAR files, to deliver malware. By password-protecting these files, they become more challenging to detect and analyze. Spear-phishing emails and malicious websites are common methods for delivering these archives. Once the malware is unleashed, it can compromise sensitive data and spread to other systems on the network.

7. HTML Phishing: Crafting Deceptive Login Pages

HTML phishing involves attackers creating fake login pages for legitimate websites using HTML code. Unsuspecting users may unknowingly enter their login credentials, which are then sent to the attackers. This tactic works effectively due to the realistic appearance of the fake login pages, leading users to believe they are interacting with legitimate websites.

HTML phishing attacks can be delivered through phishing emails and malicious websites, and once attackers obtain user login credentials, they can access sensitive data and launch further attacks.

8. Watering Hole Attacks: A Stealthy Ambush

Watering hole attacks are a type of targeted attack where attackers compromise a website known to be frequently visited by their target. The attackers then inject malware into the website, which is downloaded onto the target’s computer when they visit it. These attacks can be challenging to detect, as victims may remain unaware of the infection until it’s too late.

9. Supply Chain Attacks: Exploiting Weak Links

Supply chain attacks target a company’s partners, vendors, or suppliers to gain access to the target company’s systems. The attackers infect the partner’s system with malware, which spreads to the target company’s network when the two systems are connected. By exploiting weak links in the supply chain, attackers can bypass the target company’s security measures.

As malware delivery tactics continue to evolve, it’s crucial to maintain vigilance and keep systems up to date with the latest security patches and software. Moreover, educating employees about the latest threats and how to identify them is essential in mitigating risks.

For robust protection against advanced cyber threats, consider leveraging tools like FileTAC. With advanced analytics and threat intelligence capabilities, InQuest empowers organizations to prevent, detect, and respond to cyber threats effectively.

Stay vigilant and stay safe! Protecting your systems is an ongoing battle, but with the right knowledge and tools, you can stay one step ahead of cybercriminals in 2023 and beyond.
