How to find WS_FTP Server instances?

How to find WS_FTP Server instances? 

On September 27th, Progress Sofware announced eight vulnerabilities in the WS_FTP Server software. These issues can lead to a full compromise of exposed WS_FTP systems and their data through the FTP, SSH, and web management services, which are often externally exposed.

The four most serious vulnerabilities in this set:

  • CVE-2023-40044 (CVSS 10.0). An exposure in the web interface that leads to remote code execution through a .NET deserialization vulnerability. This is the issue most likely to be mass-exploited due to the lack of authentication and likelyhood of this web interface being exposed to untrusted networks. Rapid7 noted that this appears to be exploitable with a single HTTP POST request using an existing pauload from the ysoserial.net project.
  • CVE-2023-42657 (CVSS 9.0). An exposure in the FTP/SCP (SSH) implementation that enables file operations outside of the WS_FTP data folder through a directory traversal vulnerability. This issue can allow an attacker to access, modify, and delete files on the server, which can expose data, but also allow remote code execution in some configurations.
  • CVE-2023-40046 (CVSS 8.2). An exposure in the web interface that allows for database access through a SQL injection vulnerability. It’s not clear if a valid user account is required to access this code path, but an attacker could use this to read and modify database contents, which in turn can lead to a full server compromise.
  • CVE-2023-40049 (CVSS 5.3). An exposure in the web interface that exposes file and directory lists within the WebServiceHost folder. Although this does not lead to remote code execution on it’s own, it may be an important exposure in that it will help attackers identify systems vulnerable to the more serious issues above.

Quiz for Cybersecurity Awareness Month: 10 good-to-know facts about digital safety

Welcome to our Cybersecurity Awareness Month quiz! 

In an age where our digital footprints are larger than ever, understanding the importance of cybersecurity is vital. This quiz is designed for companies and their teams to enhance their digital safety knowledge, adopt new practices, and remain vigilant against evolving digital threats.

Are you ready to test your cybersecurity knowledge and learn some essential facts along the way? Let’s go!

1. When was Cybersecurity Awareness Month first celebrated?

Cybersecurity Awareness Month quiz 10 1400x720

Correct answer: October 2004

Cybersecurity Awareness Month was first celebrated in October 2004. Two decades ago, the President and the Congress of the US declared October the official Cybersecurity Awareness Month.

The idea behind it is to dedicate a month to raising awareness about the importance of cybersecurity, educate individuals and organizations about online threats and best practices, and promote a safer digital environment.

Over the years, this initiative helped individuals become more vigilant about online security, encouraged organizations to invest in cybersecurity measures, and fostered collaboration among governments, businesses, and the public in addressing cyber threats.

2. What’s the name of the first cyber attack?

Correct answer: Morris Worm

In November 1988, a graduate student named Robert Tappan Morris created the Morris Worm, one of the first computer worms.

Originally intended to measure the size of the internet, a coding error caused it to replicate uncontrollably, infecting thousands of computers.

This incident exposed vulnerabilities in early internet systems, led to the Computer Emergency Response Team (CERT) creation, and underscored the need for improved cybersecurity practices in the digital world.

3. When was the first antivirus software created?

Correct answer: 1980s

The first antivirus software, known as “Elk Cloner,” was created in 1982 by a high school student named Rich Skrenta.

Unlike modern antivirus tools, Elk Cloner was designed to protect Apple II computers from a playful prank: it spread by attaching itself to floppy disks and displayed a humorous poem upon activation.

While it was more of a benign experiment than a comprehensive antivirus solution, Elk Cloner marked the early beginnings of efforts to protect computers from malicious software.

4. What is the most common cyber threat?

Correct answer: Human error

Human error is the most common and pervasive cybersecurity threat. It occurs when individuals inadvertently make mistakes that compromise the security of digital systems and data. These errors can range from clicking on malicious links in phishing emails to unintentionally sharing sensitive information on public forums.

Human error is responsible for 85% of data breaches and security incidents, often leading to financial losses, reputational damage, and legal consequences for individuals and organizations.

Mitigating this threat requires a combination of user education, training, and implementing safeguards such as multi-factor authentication (MFA) and robust data protection policies based on the Zero Trust model.

5. How much did a ransomware attack cost for businesses on average in 2023?

Correct answer: $4.54 million

According to the IBM Data Breach Report of 2023, the average cost of a ransomware attack was $4.54 million. It’s challenging to pinpoint it precisely due to the many factors involved. However, it is commonly estimated to be in the hundreds of thousands to several million dollars.

These costs encompass the ransom payment (if made) and expenses related to data recovery, cybersecurity improvements, legal assistance, regulatory fines, and the significant operational disruptions that often follow such an attack.

Ransomware is one of the most malicious types of cyber attack, as the true cost can also be considerably higher when considering the long-term reputational damage and loss of customer trust.

6. Does company size matter for a malicious actor wanting to attack?

Correct answer: No, small, medium, and large companies are attacked equally often.

The size of a company doesn’t necessarily deter malicious actors from targeting it. In fact, small and medium-sized businesses are often targeted because they may have weaker cybersecurity defenses compared to larger enterprises.

Additionally, attackers might exploit smaller organizations as stepping stones to reach more substantial targets in supply chain attacks. Ultimately, cybercriminals consider factors such as vulnerabilities, potential rewards, and ease of access more than company size when deciding whom to target.

7. Top 3 industries that are the most vulnerable to cyber attacks?

Correct answer: Finance, Healthcare, Education

The finance industry is highly vulnerable to cyberattacks due to the vast amounts of valuable financial data it handles. Cybercriminals target banks, payment processors, and stock exchanges to steal funds and sensitive information.

In healthcare, the sensitivity of patient data and the increasing use of interconnected medical devices make it a prime target. Breaches can lead to identity theft, medical fraud, and even endanger patients’ lives.

The education sector faces threats as it increasingly relies on online learning platforms and stores student information. Cyberattacks in this industry can result in data breaches, educational disruptions, and the theft of personal information. Proactive cybersecurity measures are crucial for safeguarding the vulnerable education sector.

8. What does a strong password look like?

Correct answer: m#P52s@ap$V.

Strong passwords should mix upper and lower-case letters, numbers, and special symbols. Avoid easily guessable information like birthdays or common words. Never reuse passwords across multiple accounts. Each account should have its distinct, strong password to prevent a breach in one account from compromising others.

Change your passwords periodically, especially for sensitive accounts. This minimizes the risk in case a password is ever compromised.

Best cybersecurity strategies strongly recommend considering a password manager. It can generate and store complex passwords for you, making it easier to manage multiple secure logins without remembering them all. To make it even more resilient for breaches, combine passwords with MFA use.

9. What do you do if you receive an email from an unknown sender?

Correct answer: Don’t open it. If you did, don’t click on anything.

Phishing is leading the Top cyber incidents list of 2022. Phishing usually starts from an email. So, learning to recognize one is extremely important.

Here’s what to do if the email seems suspicious. First, avoid clicking on any links or downloadable attachments – they could be malicious. Then, take a close look at the sender’s email address. If it looks suspicious or doesn’t match the supposed sender, be cautious. Finally, always check for strange language, misspellings, or urgent requests. These can be signs of phishing attempts.

If the email claims to be from a company or organization, verify it independently by contacting the sender directly via alternative channels. Don’t use contact information from the suspicious email.

Mark the email as spam or junk to help train your email provider’s filters. If you’re unsure, it’s safest to delete the email. You can report it to your email provider or IT manager if it seems like a phishing attempt.

10. What does the acronym VPN stand for?

Correct answer: Virtual Private Network

A VPN, or Virtual Private Network, is like your digital secret tunnel to the internet. It keeps your online activities private and secure.

It does two cool things. First, it hides your online footprints from the snoopy eyes of malicious actors and advertisers. Second, it makes you look like you’re browsing from a different place, which is awesome for unlocking content or staying safe on public Wi-Fi.

Think of a VPN as your digital disguise. When you connect to one, it encrypts your data and sends it through a secure server in another location, masking your true identity and protecting your data from prying eyes like an online invisibility cloak.

Well done!

ESET Research: North Korea-linked Lazarus impersonates Meta on LinkedIn to attack an aerospace company in Spain

  • ESET researchers discovered a Lazarus attack against an aerospace company in Spain. Lazarus is a North Korea-linked advanced persistent threat (APT) group.
  • Employees of the targeted company were contacted by a fake recruiter via LinkedIn and tricked into opening a malicious executable file presenting itself as a coding challenge or quiz.
  • The most notable payload is the LightlessCan backdoor, implementing techniques to hinder detection by real-time security monitoring software and analysis by cybersecurity professionals.
  • The final goal of the attack was cyberespionage.

BRATISLAVA, PRAGUE — September 29, 2023 — ESET researchers have uncovered a Lazarus attack against an aerospace company in Spain, in which the group deployed several tools, most notably the newly discovered backdoor named LightlessCan by ESET. Operators of the North Korea-linked Lazarus group obtained initial access to the company’s network last year after a successful spearphishing campaign, masquerading as a recruiter for Meta — the company behind Facebook, Instagram, and WhatsApp. The final goal of the attack was cyberespionage.

“The most worrying aspect of the attack is the new type of payload, LightlessCan, a complex and possibly evolving tool that exhibits a high level of sophistication in its design and operation, and represents a significant advancement in malicious capabilities compared to its predecessor, BlindingCan,” explains ESET researcher Peter Kálnai, who made the discovery.

The fake recruiter contacted the victim via LinkedIn Messaging, a feature within the LinkedIn professional social networking platform, and sent two coding challenges supposedly required as part of a hiring process, which the victim downloaded and executed on a company device. ESET Research was able to reconstruct the initial access steps and analyze the tool set used by Lazarus thanks to cooperation with the affected aerospace company. The group targeted multiple company employees.

Lazarus delivered various payloads to the victims’ systems; the most notable is a previously publicly undocumented and sophisticated remote access trojan (RAT) that we named LightlessCan. The trojan mimics the functionalities of a wide range of native Windows commands, usually abused by the attackers enabling discreet execution within the RAT itself instead of noisy console executions. This strategic shift enhances stealth, making detecting and analyzing the attacker’s activities more challenging.

Another mechanism used to minimize exposure is the employment of execution guardrails: Lazarus made sure the payload could be decrypted only on the intended victim’s machine. Execution guardrails are a set of protective protocols and mechanisms implemented to safeguard the integrity and confidentiality of the payload during its deployment and execution, effectively preventing decryption on unintended machines, such as those of security researchers.

LightlessCan has support for up to 68 distinct commands, but in the current version, 1.0, only 43 of those commands are implemented with some functionality. ESET Research has identified four different execution chains, delivering three types of payloads.

The Lazarus group (also known as HIDDEN COBRA) is a cyberespionage group linked to North Korea that has been active since at least 2009. The diversity, number, and eccentricity in implementation of Lazarus campaigns define this group, which performs all three pillars of cybercriminal activities: cyberespionage, cybersabotage, and pursuit of financial gain. Aerospace companies are not an unusual target for North Korea-aligned APT groups. The country has conducted multiple advanced missile tests that violate United Nations Security Council resolutions.

For more technical information about Lazarus, its latest attack, and the LightlessCan backdoor, check out the blog post “Lazarus luring employees with trojanized coding challenges: The case of a Spanish aerospace company” on WeLiveSecurity. ESET Research will present findings about this attack at the Virus Bulletin conference on October 4, 2023. Make sure to follow ESET Research on Twitter (today known as X) for the latest news from ESET Research.

Austin, TX – October 12, 2022 — Portnox, a proven leader in cloud-native, zero trust access and endpoint security solutions, today announced the general availability of the first cloud-native IoT security solution to help mid-market and enterprise businesses address rising Internet of Things (IoT) security threats. Now available via the Portnox Cloud, Portnox’s new IoT fingerprinting and profiling capabilities empower organizations to easily and accurately identify, authenticate, authorize, and segment IoT devices across their network to ensure an effective zero trust security posture.

“No organization is immune to the inherent and increasing number of security risks IoT devices pose as they are more susceptible to vulnerabilities and, therefore, prime targets for cyberattacks. Companies of all sizes must properly secure these devices to prevent them from serving as a gateway onto the corporate network by cybercriminals. But as networks become more complex and distributed, and as the number of IoT devices continues to grow, it’s becoming more and more difficult to identify and control access for these devices across a given network, let alone secure them,” said Denny LeCompte, CEO at Portnox.  “As we bring our vision of simplifying access control and endpoint security for mid-market IT teams to fruition, adding a solution for IoT fingerprinting  to our cloud-native platform was the natural next step. Portnox now gives customers full visibility of IoT devices in use across their respective networks.”

Juniper Research predicts that the total number of IoT connections will surge to 83 billion by 2024, while Ponemon Institute found that most (94 percent) organizations think that a security incident related to unsecured IoT devices or applications could be “catastrophic”. Large enterprises are not alone when it comes to rising IoT security headaches – organizations of all sizes are actively trying to strengthen their security postures to account for the surge of threats tied to the rising operational dependence on IoT. With so many IoT devices – printers, cameras, thermostats, sensors, monitors, etc. – now in use across all types of organizations, the ability to automatically onboard and enforce IoT device authentication, control and security policies across the network is mission critical.

Already helping more than 1,000 organizations navigate ever-changing cybersecurity threats, Portnox solutions are purpose-built to be exceptionally easy-to-use, scale, and manage. With the addition of IoT fingerprinting and profiling to the Portnox Cloud, Portnox customers can now enjoy enhanced confidence in the security posture of their network with respect to IoT – without the cost and resource demands associated with traditional on-premise IoT security solutions that can often be complex to configure, deploy, and maintain.

With the latest solution expansion, the Portnox Cloud now provides organizations with:

  • Complete device visibility and access policy enforcement across the network for all major device groups – IoT, bring your own device (BYOD) and managed devices
  • Enhanced IoT fingerprinting and profiling accuracy powered by artificial intelligence and machine learning
  • Strengthened organizational zero trust security postures, accounting for all devices and access layers – on-site and remote

This technology will unlock a tremendous number of additional capabilities, such as automatic policy mapping based on fingerprints and leveraging fingerprinting data to thwart potential MAC Address spoofing risks. Portnox customers can also use fingerprinting information to provide EoL/EoS dates, as well as list potential security vulnerabilities on the endpoint to augment network access and remediation policies.

Portnox continues to rapidly expand its zero trust security offerings across the Portnox Cloud. The company is currently exploring new ways to add agentless risk assessment policy enforcement, as well as data capture options to increase IoT fingerprinting access and automate micro-segmentation and quarantining for IoT devices in future iterations of the solution.

“Providing intelligent insight and visibility into IoT devices connecting to a business’s network with absolutely zero on-prem footprint required is absolutely unprecedented,” said Portnox Vice President of Product Management Jeremy Morrill. “From somewhat basic IP phones, security cameras, printers, TVs and streaming appliances, to complex medical devices and manufacturing equipment, the need for comprehensive IoT security has never been more critical – especially as the proliferation of IP-connected devices continues to accelerate and shows no sign of slowing.”

Effective immediately, IoT fingerprinting and profiling will now be automatically included in Portnox’s NAC-as-a-Service subscription for organizations with 500+ devices. Find more details on pricing packages here or access more product facts here.

Enhancing Network Security with Network Access Control Lists (NACLs)

With the constant threat of cyberattacks, network engineers and administrators must implement robust security measures to safeguard their networks. One such measure is the Network Access Control List (NACL), a vital component in the arsenal of network security tools. In this comprehensive guide, we’ll delve into what NACLs are, why they are essential, and how they can help thwart cyberattacks. We’ll also explore real-world examples to highlight the importance of implementing NACLs in your network infrastructure.

Understanding Network Access Control Lists (NACLs)

Before we dive into the importance of NACLs, let’s clarify what they are. A Network Access Control List (NACL) is a security feature used in networking to filter traffic and control access to network resources. Think of it as a virtual checkpoint or gatekeeper for your network. NACLs are commonly used in cloud-based environments, such as Amazon Web Services (AWS), and they are essential for enforcing security policies.

Why Network Engineers and Administrators Need NACLs

1. Defense in Depth

Network security is not a one-size-fits-all solution. It requires a multi-layered approach to defend against a wide range of threats. A network access control list play a crucial role in this defense in depth strategy by adding an extra layer of security to protect your network. By setting up NACLs, you can specify rules that determine which traffic is allowed and which is denied. This level of granularity is essential to control access and prevent unauthorized users or malicious entities from infiltrating your network. NACLs allow you to create an additional barrier beyond traditional firewalls and security measures.

2. Granular Control

One of the standout features of NACLs is their ability to provide granular control over network traffic. You can define specific rules to allow or deny traffic based on source IP addresses, destination IP addresses, port numbers, and even protocols. This granular control enables you to tailor your network’s security to your organization’s specific needs.

3. Protecting Sensitive Data

Networks often contain sensitive and confidential data that must be protected at all costs. NACLs are instrumental in safeguarding this data by ensuring that only authorized users or systems can access it. For example, an e-commerce company can use NACLs to restrict access to its customer database to only the systems responsible for processing orders and customer support.

Real-World Examples of NACLs in Action

To better illustrate the importance of NACLs in network security, let’s explore some real-world scenarios where a network access control list could have helped thwart cyberattacks:

1. Preventing Unauthorized Access

Consider a financial institution that stores customer data on its servers. Without NACLs, malicious actors could potentially gain unauthorized access to this sensitive information, leading to a data breach. By implementing NACLs, the institution can restrict access to only trusted IP addresses, making it significantly more challenging for attackers to infiltrate the network.

2. Mitigating DDoS Attacks

Distributed Denial of Service (DDoS) attacks can cripple a network by overwhelming it with a flood of traffic. NACLs can be used to mitigate the impact of DDoS attacks by blocking traffic from known malicious IP addresses. This proactive approach helps maintain network availability and ensures that legitimate users can access resources without disruption.

3. Securing Cloud-Based Environments

In cloud-based environments like AWS, NACLs are essential for securing virtual private clouds (VPCs). In 2020, the SolarWinds cyberattack compromised numerous organizations, highlighting the importance of securing cloud-based resources. Implementing NACLs in VPCs can prevent unauthorized lateral movement within the network and limit the potential damage of such attacks.

4. Protecting Internet of Things (IoT) Devices

IoT devices are often vulnerable to cyberattacks due to their limited security features. NACLs can be used to isolate and secure these devices, ensuring that they can only communicate with authorized servers and services. This prevents attackers from exploiting vulnerable IoT devices to gain access to the broader network.

How to Create Effective NACLs

Now that we understand why NACLs are crucial, let’s explore how to create effective ones:

  1. Define Your Security Objectives: Before creating NACLs, establish clear security objectives. Identify what you need to protect and the level of access required for different parts of your network.
  2. Create Rules Based on Least Privilege: Follow the principle of least privilege, which means granting only the minimum access necessary for a resource to function. Restrict access to resources to reduce the attack surface.
  3. Regularly Review and Update Rules: Network environments are dynamic, and threats constantly evolve. Regularly review and update your NACL rules to adapt to changing security requirements and emerging threats.
  4. Monitor Traffic and Logs: Implement robust traffic monitoring and log analysis to detect any anomalies or unauthorized access attempts. Timely detection can prevent potential security breaches.
  5. Test NACLs: Before deploying NACLs in a production environment, thoroughly test them in a controlled setting to ensure they function as intended without disrupting legitimate traffic.

Final Thoughts on NCLs

Network Access Control Lists (NACLs) are indispensable tools in the arsenal of network engineers and administrators for enhancing network security. They provide a critical layer of defense in depth, offering granular control and protecting sensitive data. By implementing NACLs, you can prevent unauthorized access, mitigate DDoS attacks, secure cloud-based environments, and protect IoT devices. As cyber threats continue to evolve, NACLs serve as a vital safeguard, helping to thwart potential cyberattacks. Remember to define your security objectives, follow the principle of least privilege, and regularly update and monitor your NACL rules to keep your network safe. NACLs are not a one-time solution; they require ongoing attention and adaptation to stay effective in the ever-changing landscape of network security.
