CTM360 Hardening Guidelines

SolarWinds - an American software vendor for managing networks and infrastructure has been breached. Orion, a network monitoring product was modified by a state-sponsored threat actor via embedding backdoor code into a legitimate SolarWinds library. This allowed remote access into the victim’s environment and a foothold in their networks; this enabled attacker to obtain privileged credentials.

The SolarWinds Orion products are designed to monitor the networks of systems and report on any security issues. Due to this, there are no comparable limiting boundaries on the scope or potential security impact; this has been made clear by the gradual revelation of more and more high-value targets. Even more worrisome is the fact that the attackers apparently made use of their initial access to targeted organizations, such as FireEye and Microsoft, to compromise tools and code that would then enable them to target other victims. After Microsoft discovered that they were breached via the SolarWinds compromise, they further discovered that their own products were then used “to further the attacks on others.”

The attack was initially disclosed by the cybersecurity firm, FireEye, as early as December 8th but published publicly on 13th. It was revealed that the attack on SolarWinds was conducted by an unknown APT (Advanced Persistent Threat) group. They were able to steal Red Team assessment tools, similarly, used by FireEye to probe its customers’ security. FireEye has made its countermeasures freely available on GitHub.

According to Microsoft, hackers acquired superuser access to SAML token-signing certificates. This SAML certificate was then used to forge new tokens to allow hackers to obtain trusted and highly privileged access to networks.

While analyzing further on this attack, it was discovered that there was another backdoor likely from a second threat actor. This malware was dubbed as SUPERNOVA. This was a web shell planted in the code of the Orion network and applications monitoring platform and enabled attackers to run arbitrary code on machines running the trojanized version of the software.

Hackers inserted malicious code into an updated version of the software, called Orion. Approximately 18,000 SolarWinds customers installed tainted updates, between March and June 2020, onto their systems. The malware was inserted in these Orion app versions:

• Orion Platform 2019.4 HF5, version 2019.4.5200.9083
• Orion Platform 2020.2 RC1, version 2020.2.100.12219
• Orion Platform 2020.2 RC2, version 2020.2.5200.12394
• Orion Platform 2020.2, 2020.2 HF1, version 2020.2.5300.12432

This disclosure was followed by a coordinated report issued by Microsoft, FireEye, SolarWinds, and the U.S. government. The report concluded that SolarWinds had been targeted by threat actors who aimed to gather undisclosed information from major customers of theirs, including FireEye.

Compromise: What is Known so Far

A key indicator of the attack was the conceived backdoor that was able to gain access to and breach the SolarWinds Orion build system. This backdoor was attached to the said system by rescripting the legitimate SolarWinds.Orion.Core.BusinessLayer.dll DLL file. This file was then distributed to SolarWinds’ clients in a supply chain attack. This was achieved due to an automatic update platform used to dispense new software updates; clients were unaware of this taking place.

According to reports, the threat actors may have performed trial runs of the distribution method as early as October 2019. Researchers believe that the attackers had already compromised networks previously; it is suggested that they had harvested information or performed other malicious activities silently for months. Due to this, FireEye eventually detected that they were hacked after the threat actors registered a device to the company’s multi-factor authentication (MFA) system using stolen credentials. The alert from the system, regarding an unknown device, was able to notify FireEye of the compromise.

Recommendations

Urgently update any exploited SolarWinds Orion software to Orion Platform version 2020.2.1 HF 2 and Orion Platform 2019.4 HF 6

Third party vendors who may be susceptible to exposure of this compromise should report as part of responsible disclosure and urgently remediate.

In case of possible exposure devise an incident response plan.

In an increasingly interconnected digital world, organisations face a growing number of cyber threats. As businesses expand their online presence, their attack surface increases, making it more vulnerable to cyberattacks. This is where External Attack Surface Management (EASM) comes into play.

In this blog, we will explore the concept of EASM, what it includes, its importance, how it differs from security ratings, and what the future holds for this crucial aspect of cybersecurity. Additionally, we’ll discuss how CTM360 HackerView can help your organisation effectively manage its external attack surface.

What is EASM?

External Attack Surface Management (EASM) involves the continuous discovery, monitoring, and management of an organisation’s external-facing digital assets. These assets include websites, IP addresses, cloud services, and any other publicly accessible resources. A comprehensive EASM would also have the organisation’s mobile apps, genuine social media inventory, Executive Management profiles and more.  EASM focuses on first building a comprehensive “Digital Asset Register” and next identifying vulnerabilities and potential entry points that could be exploited by malicious actors. By gaining a deep understanding of the external attack surface, organisations can proactively mitigate risks and prevent breaches before they occur.

From the management perspective, EASM is an essential component of a robust cybersecurity strategy. It enables organisations to see their digital footprint from the perspective of an attacker, allowing them to identify and secure weak points that could be targeted.

What is Included in an Organization’s Attack Surface?

An organisation’s attack surface consists of all the external-facing digital assets that could potentially be targeted by cybercriminals. These include:

Domains, Hosts, and Sub-Domains:

An organization’s collection of domains, along with their associated hosts and sub-domains, creates numerous potential entry points for attackers. Each sub-domain may have unique vulnerabilities that can be exploited if not properly secured.

Web Applications:

Public-facing websites and web applications are common targets for attackers seeking to exploit vulnerabilities such as outdated software or weak authentication mechanisms.

Cloud Services:

With the rise of cloud computing, organisations often use cloud-based services for data storage and processing. Misconfigurations or insufficient security measures in these services can expose sensitive information.

IP Addresses:

Public IP addresses can be scanned by attackers to identify open ports or vulnerable services that can be exploited.

Third-Party Integrations:

Organisations often rely on third-party vendors or services that have access to their systems. These integrations can introduce additional vulnerabilities if not properly managed.SSL/TLS Certificates:

Weak or expired certificates can leave encrypted communications vulnerable to interception.

A comprehensive EASM solution would also include -

Inventory of Genuine Social Media Profiles:

An organisation's presence on social media platforms can be targeted by attackers for impersonation or phishing attempts.

Mobile Apps:

Attackers can create rogue mobile apps on third party stores to impersonate trusted brands, with the goal of gaining unauthorised access to information that can be used to commit fraudulent transactions.

Executive Management Names/Profiles:

Attackers may attempt to impersonate an organisation's executive leadership for social engineering attacks.

BIN Numbers:

Payment card information, including BIN (Bank Identification Number) data, can be exposed and used for fraudulent activities.

Environments & Technologies:

The list of technologies and their respective versions visible in the organisation's attack surface can help identify potential vulnerabilities and misconfigurations.

The attack surface also includes shadow IT, which refers to information technology systems implemented by departments outside of the central IT department to circumvent the limitations and restrictions set by the central information systems.

Why is EASM Important?

EASM is critical for several reasons:

1. Technology  consolidation

EASM promotes a unified security strategy, enabling organizations to consolidate their ever growing digital assets and stack of technologies and enhance the overall management of external cyber risk.

2. Reducing Attack Surface

Through continuous monitoring and assessment, EASM assists organizations in reducing their attack surface by proactively managing and securing external assets.

3. Proactive Risk Management:

EASM allows organisations to identify vulnerabilities before they are exploited. By continuously monitoring the attack surface, organisations can address security gaps promptly, reducing the likelihood of a successful attack.

4. Real-Time Visibility:

Cyber threats are constantly evolving, and new vulnerabilities emerge regularly. EASM provides real-time visibility into an organisation’s external assets, ensuring that security teams are always aware of the current state of the attack surface.

5. Regulatory Compliance:

Many industries are subject to strict regulatory requirements regarding data protection and cybersecurity. EASM helps organisations maintain compliance by ensuring that all external assets are properly secured.

6. Cost Efficiency:

Preventing a cyberattack is often far less expensive than dealing with the aftermath of a breach. EASM enables organisations to allocate resources more efficiently by prioritising the most critical vulnerabilities.

How is EASM Different from Security Ratings?

While both EASM and security ratings play a role in assessing an organisation’s cybersecurity posture, they serve different purposes and offer distinct benefits:

1. Scope of Analysis:

Security ratings are typically based on a broad assessment of an organisation’s overall security practices, often using data from public sources. EASM, on the other hand, focuses specifically on the external attack surface, providing a more detailed and targeted analysis of potential vulnerabilities.

2. Continuous Monitoring:

EASM involves continuous monitoring of external assets, offering real-time insights into the attack surface. Security ratings are often static, providing a snapshot of an organisation’s security posture at a specific point in time.

3. Actionable Insights:

EASM provides actionable insights that organisations can use to address specific vulnerabilities. Security ratings are more generalised and may not offer the same level of detail needed to implement targeted security measures.

4. Perspective:

EASM approaches cybersecurity from the attacker’s perspective, identifying entry points and weaknesses that could be exploited. Security ratings focus on the organisation’s overall security practices and controls.

What Does the Future Hold?

As cyber threats continue to evolve, the importance of EASM will only grow. Organisations are increasingly adopting digital transformation strategies, expanding their digital footprints, and moving more services to the cloud. This expansion introduces new vulnerabilities, making EASM an essential component of any comprehensive cybersecurity strategy.

In the future, we can expect EASM tools and technologies to become more sophisticated, incorporating advanced AI and machine learning algorithms to identify and mitigate risks more effectively. The integration of EASM with other cybersecurity solutions, such as Security Information and Event Management (SIEM) and Endpoint Detection and Response (EDR), will provide organisations with a more holistic approach to managing their security posture.

Global Fraudulent Scheme Targeting National Immigration Services

Overview

CTM360 has identified a fraudulent scheme involving fake websites targeting National Immigration services globally. The deceiving campaign extends to Electronic Travel Authorization, Evisa, and Electronic Custom Declaration processes. These scams have increased dramatically as more things shifted online and require less paperwork. Scammers take advantage of this by making fake websites. People need to be aware of this and be careful not to get tricked.

These fake websites usually use a basic web design and are hosted on well-known hosting services to look real. Additionally, these fake websites put up disclaimers in fine print stating to be private companies and have no affiliation with any government entities. By doing this, it makes it challenging for the Hosting Providers and Domain Registrars to take action on them.

CTM360 Observations

Based on our analysis of the suspicious infrastructure, we believe these fake websites are part of a broader scam campaign targeting multiple immigration services at the same time. Some of the top countries being targeted include Singapore, South Korea, the Philippines, and Turkey. We expect this scam to also occur in other countries in the near future.            

The scam initiates with scammers paying for fake ads on search engines, so they show up at the top of search results. They manipulate the search engine algorithms to get their fake sites noticed more easily. This technique makes it more likely for people to accidentally find these fake websites. The ads are constructed in a way that makes the fake sites seem real, so people might trust them without realizing they're being tricked.

When clicking on the fake ad, users will be redirected to a fake website. On the fake website, they will be prompted to initiate the online visa application process. The process found on the fake website is crafted closely to mimic the procedures found on the official website.

After entering the card details, users will be consistently displayed with error messages falsely claiming payment failures. In reality, the sensitive carding information has already been captured and submitted to the server controlled by the scammers.
Moreover, numerous countries have issued official warnings advising against such fake websites. Please refer to the following sources for more information:

Recommendations

How to avoid becoming a victim of such scams

For individuals:

• Be very cautious about the sponsored ads specifically about government services.
• When applying for any travel-related services, only use the official website provided by the immigration authorities of the country you're visiting. This may require some research by individuals to ensure they have reached the genuine website.
• Be cautious about clicking on suspicious web URLs, even if they seem to come from people you know.

For Government agencies, ISPs and Domain Registrars:

• Government service providers should publish a list of authorized agents on their websites. This will enable end-users to verify the right provider. Furthermore, it will also provide evidence for the Domain registrar to take prompt action.
• Government agencies are advised to regularly monitor such fake websites that do not have any authorization from the government and update the list of these fake websites on their official portal.
• Government agencies should actively engage with security vendors to identify and take down these fake websites and fake ads.
• There should be national procedures for Local ISPs and National CERTs to block such websites once notified by the right authorities.
