Protecting your Organization from Emotet and the Omnatuor Malvertising Network
Written by Mohammed Al-Moneer, Regional Director, META at Infoblox
In the last edition of our Quarterly Cyber Threat Intelligence Report, Infoblox brings into focus and provides insights into two major cyber threats that organizations should be aware of – Emotet and Omnatuor Malvertising Network.
EMOTET
Emotet is a notorious malware family that has evolved significantly over the years: from a simple banking trojan to a botnet to an infrastructure for content delivery. Infoblox has been monitoring Emotet and providing insights into its activity all along. Emotet has been around since 2014. It survived its January 2021 takedown by law enforcement agencies from the Netherlands, UK, and US and from Germany, France, Lithuania, Canada, and Ukraine. During the takedown, Emotet was offline for 11 months.
The frequency of Emotet-related malspam campaigns increased from January to May 2022 as the malware authors changed techniques to evade Microsoft’s increasing countermeasures on VBA Macro security. The Max Planck Institute for Plasma Physics was attacked on 12 June 2022, and recent reports put Emotet back at the top of the list of malware families with an impact that spans the globe. A consistent feature of Emotet has been its use of email as a delivery vector. Microsoft Office documents have been the attachments of choice, and Excel files have been the most prevalent of these documents.
Infoblox’s analysis indicates that the actors behind Emotet have made some attempts to protect the network from further takedowns. Perhaps unsurprisingly, the use of compromised websites and of email as a delivery vector has persisted, and this has enabled us to reliably identify and track Emotet’s activity. Infoblox’s view of the threat landscape affords a detailed understanding of not only the current prevalence of Emotet in malspam, but also of the location and services used in its infrastructure.
As our company continues to research and monitor Emotet’s behavior, it will provide protection by denying access to the compromised domains used to host the Emotet payload, and it will offer vital, actionable intelligence on Emotet’s C&C infrastructure.
We recommend the following actions for protection from this kind of attack:
- To mitigate the risk of infection from known threats, keep security software up to
date and patched. - Conduct security awareness training in the organization. It is important for
everyone to be up to date with the latest techniques used by attackers to trick
users who receive malicious emails. - Enhance network perimeter security. 99% of successful attacks involve some
type of network communication. Having the right tools in place can help identify
and minimize the impact of a threat like Emotet before they cause damage
OMNATUOR MALVERTISING NETWORK
For some time, the Infoblox Threat Intelligence Group has been tracking a malvertising network (the “Omnatuor Malvertising Network”) that not only abuses push notifications, pop-ups, and redirects within a browser but continues to serve ads even after the user navigates away from the initial page.
Omnatuor has been dismissed by the security community as adware, a label that implies the activity is largely a nuisance. This naive response underestimates the danger of the potential threat posed by malvertising in general, and the Omnatuor actor in particular. In addition to its ability to persist, the network delivers dangerous content.
The Omnatuor actor takes advantage of WordPress vulnerabilities and is effective at spreading riskware, spyware, and adware. It uses an extensive infrastructure and has a broad reach into networks across the globe. The Omnatuor domain has a suspiciously high breadth and query volumes.
An initial look into WHOIS data revealed the domain was created on 12 July 2021. Since being registered it was present in 45% to 48% of all customer networks and surpassed 50% at various times. Most networks contained tens, if not hundreds, of thousands of queries for the domain. From July 2021 to July 2022, we observed just over 25.4 million unique, resolved queries to omnatuor[.]com.
This campaign compromises vulnerable WordPress sites through embedded malicious JavaScript or PHP code. The code redirects users or otherwise forces them to view and click malvertisements via pop-ups and push notifications.
We recommend that users take the following preventive measures:
- To assist in blocking known malvertising efforts, leverage the GitHub repository of indicators associated with the Omnatuor Malvertising Network.32 Infoblox offers a sample of indicators in this article and will continue to update the GitHub repository as new indicators are discovered.
- Use an adblocker program, such as UBlock Origin. The adware is delivered via an inline script, and blocking only the domains and IP addresses at a firewall or DNS level will not stop push notifications, redirects, or pop-ups. Because the DNS query cannot be completed, the contents of those vectors will not load; however, the browsing experience will still be interrupted.
- Disable JavaScript entirely, or use a web extension (such as NoScript) to enable JavaScript only on trusted sites.

SANS Institute to Boost Cyber Resilience in Bahrain and Qatar
SANS Institute is set to bring world-class cybersecurity education to professionals across the Middle East with SANS Manama (7-12 September) at InterContinental Bahrain, followed by SANS Doha (14-19 September) at InterContinental Doha. The courses are designed to educate professionals on current and emerging cyber threats, ensuring that participants are confident in the latest industry trends, tools, and techniques.
SANS Manama September 2024 (7-12 September) offers the following courses:
- FOR508: Advanced Incident Response, Threat Hunting, and Digital Forensics
- LDR414: SANS Training Program for CISSP Certification
FOR508 is an in-depth course that equips incident responders and threat-hunting teams with advanced skills to detect, identify, counter, and recover from a wide range of threats within enterprise networks, including those posed by nation-state adversaries, organized crime syndicates, and ransomware operators. LDR414 is an accelerated review course specifically designed to prepare students for the CISSP exam. It focuses exclusively on the eight domains of knowledge defined by (ISC)², which are critical to passing the exam.
A highlight of SANS Manama will be the Community Night session on 9 September, titled “Justice Denied: How Bad Digital Forensics Threatens and Undermines Justice.” This session will delve into three real-world cases—one criminal and two civil—to demonstrate how digital forensic evidence, when presented by unqualified or biased practitioners, nearly destroyed lives in court. The session will also illustrate how a proper scientific approach to digital forensics can help achieve justice.
SANS Doha September 2024 (14-19 September) will feature:
- SEC504: Hacker Tools, Techniques, and Incident Handling
- SEC560: Enterprise Penetration Testing
SEC504 will teach students how to effectively respond to breaches across Windows, Linux, and cloud platforms, providing insight into the tools and techniques attackers use, the artefacts they leave behind, and how to build better defences based on this knowledge.
SEC560 is designed to strengthen the skillset of penetration testers while also training system administrators, defenders, and other security professionals to understand the mindset and methodologies of modern attackers.
Ned Baltagi, Managing Director for the Middle East, Africa, and Turkey at SANS Institute, emphasized the importance of these events, by saying, “As cybersecurity threats continue to evolve, professionals in the Middle East must stay ahead of the curve. These training sessions are not just about learning new skills—they are about building a stronger, more resilient cybersecurity community. We are committed to empowering individuals with the knowledge and tools they need to protect their organizations and, by extension, the region as a whole.”

MENA Region Sees Surge in Managed Security Services Adoption, Says SearchInform
SearchInform, the leading information security and risk management solutions vendor, has conducted an extensive survey among organizations in the Middle East and North Africa (MENA) region to assess their approach to information security. The results show a significant shift towards outsourcing security functions, with nearly 70% of organizations either already using Managed Security Services (MSS) or planning to do so shortly.
This survey involved business executives, information technology and security (IT, IS) professionals, and Chief Information Security Officers (CISOs) from both public and private sectors. The research aimed to evaluate the current state of corporate protection and identify priorities in ensuring information security amid the region’s unique challenges. Notably, 80% of respondents reported an increase in their information security budgets over the past year, reflecting a growing recognition of the need for robust security measures. Only 22% of respondents reported budgets haven’t changed, no one reported a decrease in budgets.
SearchInform’s findings indicate that while many organizations have implemented basic cybersecurity measures such as Antivirus, Next-Generation Firewalls (NGFW), Intrusion Detection Systems (IDS), Intrusion Prevention Systems (IPS) and Endpoint Protection Systems (EPS); there is still a significant gap in the deployment of more advanced systems like Data Loss Prevention (DLP) and Security Information and Event Management (SIEM). These tools are critical for real-time monitoring and internal threat protection, yet only 29% of companies have implemented DLP, and a mere 5% have adopted SIEM systems.
Lev Matveev, Chairman of the Board of Directors at SearchInform, commented on the survey results, stating, “The increasing reliance on MSS highlights the ongoing shift in how organizations are approaching their cybersecurity needs. Outsourcing provides access to specialized expertise and technology, which is particularly vital in regions facing a shortage of skilled information security professionals.”
The research also revealed that internal threats are coming to the fore. More than half of respondents admitted experiencing one or more information security incidents, caused by insider actions. “To effectively combat internal threats, increasing the cybersecurity literacy of employees will reduce the risk of undesirable incidents. The second measure is the implementation of protective solutions that help prevent both accidental and deliberate incidents, such as data leaks, corporate fraud cases, theft, kickbacks and bribery, illicit access to confidential data, etc. In this regard, the integration of DLP and DCAP systems is necessary. DCAP-class systems that perform corporate file system analysis, classify data stored in the organization, handle the task of distributing access rights, and prevent the risk of data leakage and misuse at the initial stage. These are important components of the protective system, and the concept of DCAP systems is highly recommended by Gartner experts,” Matveev commented.
As the demand for MSS continues to grow, SearchInform’s local subsidiary in the UAE has seen strong interest from both businesses and governmental organizations, underscoring the importance of managed services in addressing the region’s complex security challenges. The global MSS market size is expected to grow from USD 30.6 billion in 2023 to USD 52.9 billion by 2028, with a Compound Annual Growth Rate (CAGR) of 11.5%.

Positive Technologies: 16% of Darkweb Listings Involve Middle Eastern Organisations
In 2024, cyber criminals have shifted focus from personal data to stealing company credentials and trade secrets. One in six listings (16%) on the dark web featuring stolen government data involves organizations in the Middle East. This insight comes from Positive Technologies’ first study on data breaches in Russia, the Middle East, and globally. Their experts reviewed over 1,000 dark web listings and 700 public incident reports from the first half of 2024 worldwide.
Credential leaks from organisations hit a record high of 21% in the first half of 2024, up 9 percentage points from last year. The theft of commercial secrets and restricted information rose to 24% in the first half of 2024, an increase of 10 percentage points compared to the same period in 2023. Meanwhile, personal data theft incidents returned to pre-peak levels: dropping to 2022 levels in Q1 2024 to 37%, and then falling to 25% in Q2 2024.
In the first half of 2024, the industrial sector (39%), government agencies (36%), and transportation companies (29%) continued to lead in the share of leaks of commercial secrets and other restricted information. Notable victims include Hyundai Motor Europe and Volkswagen, with the latter losing documents on electric vehicle technology. IT companies are also at risk, with breaches involving internal processes and products accounting for 29% of incidents. In 2024, hackers allegedly accessed the source code of some Apple and AMD software.
Stolen credentials are often used for further attacks on these companies’ clients, primarily government organizations. Credential compromise is typically a step before more severe actions, such as theft of funds or system disruption. Ransomware was used in nearly a third of successful breaches involving data leaks. Dark web listings for government data heavily feature Middle Eastern countries (16%), with Asia (33%) in the lead, followed by Latin America and the Caribbean (18%). These regions are targeted by APT groups, mainly focusing on the public sector. Positive Technologies’ research on APT groups in the Middle East and Southeast Asia provides more details.
“Credentials are frequently sold on dark web forums, a key revenue source for cybercriminals. In March, access to a prominent UAE Bank’s website was listed for $10,000. The rise in these leaks is evident on the dark market—forums now offer access to dozens or hundreds of companies per post. In April, a listing was posted offering access to the infrastructure of 16 companies from various industries across Latin America, the Middle East, Europe, and Asia, with prices ranging from $250 to $5,000. According to the listing’s authors, these firms’ revenues range from $4 million to $2.8 billion. For instance, a UAE-based consumer electronics company with $6.5 million in revenue had its data valued at $400. In June, another listing offered credentials for over 400 companies, including access via Jira, GitHub, and GitLab,” notes Anna Golushko, Senior Analyst at Positive Technologies.
The number of dark web ads offering free information is nearly double those selling it (64% vs. 33%). This is because not all attackers aim to sell data; many demand ransom not to disclose it, though not all victims pay. In the first half of 2024, government organizations were often targeted specifically to steal personal data. More than half of ads on the dark web are priced under $1,000. Every tenth ad belongs to the most expensive category at $10,000 or more.
The most expensive offers (over $50,000) involve major financial institutions, retail giants, and IT companies. In Q2 2024, EDR developer Cylance suffered a cyberattack, resulting in 34 million emails and an unspecified volume of customer and employee data being sold for $750,000. Positive Technologies analysts highlight that every second successful attack on organizations in H1 2024 resulted in the leakage of confidential data. The largest number of incidents occurred in government agencies (13%), IT companies (12%), and industrial companies (11%).
Preventing data leaks requires a comprehensive approach, including tools to protect user devices, corporate networks, and the data itself. As corporate data infrastructures evolve into complex systems that are constantly changing rapidly, a unified solution is essential to safeguard information, regardless of its complexity or location.
