What We Know About The MailChannels Spoofing Issue

The news comes after the recent Defcon hacking conference where Marcello Salvati, a researcher affiliated with Rapid 7, gave an eye-opening talk that demonstrated a method for leveraging the “biggest transactional email service” and Cloudflare, effectively circumventing the safeguards of SPF (Sender Policy Framework) and DMARC (Domain-based Message Authentication, Reporting, and Conformance).

While the initial insights shared during the talk have seen some partial mitigation measures implemented, particularly with the use of Cloudflare workers and MailChannels, a disconcerting concern still persists.

What is the ongoing risk to MailChannels Users?

The issue poses a substantial risk for MailChannels customers, as well as those whose hosting providers rely on their services. Even if your domain has SPF and DMARC measures well-configured, the possibility remains that your domain could be maliciously spoofed by other MailChannels customers.

This alarming revelation underscores the persistent challenges in ensuring the security and authenticity of email communications, compelling organisations to remain vigilant and consider additional protective measures to safeguard their digital identities.

What’s The Impact on MailChannels Services?

Inclusion of the MailChannels SPF record may expose domains and users to impersonation risks. A recent solution has been introduced to address this concern. Given that a significant portion of the 2 million domains lacks these protective measures, it opens the door to widespread misuse of the MailChannels service.

The author highlights the absence of sender identity verification, allowing anyone to register on their website for a mere $80 and employ their “normal” SMTP relay to maliciously spoof customer domains.

Furthermore, another discovery reveals the adoption of a novel email service known as ARC, which inherently reduces spam scores.

Solace Cyber’s threat researchers, utilising SMTP, have validated these findings as genuine threats, emphasising the importance of organisations implementing countermeasures promptly.

Solace Cyber Recommendations

Ensure that your organisation has adequate email safeguards activated, including SPF, DMARC, and DKIM protocols.

Confirm the integrity of your SPF records and check for the presence of MailChannels. If you do, it will look like this: “” Ensure the necessity of all other entries in your SPF record, and if the MailChannels entry is unnecessary, remove it from your SPF configuration, along with any other superfluous entries.

Alternatively, if you require the MailChannels SPF record, add the recommended MailChannels lockdown TXT record. You may need to speak to your webhosting provider.

  1. Create a DNS TXT record following the pattern, replacing with your domain name.
  2. In the DNS TXT record, specify one or more MailChannels account ids (auth) or sender ids (senderid) that are permitted to send emails for their domain, using the following syntax: v=mc1 auth=myhostingcompany senderid=mysenderid

Furthermore, it is advisable to evaluate your supply chain for potential vulnerabilities in their email configurations.

    Solace Cyber security specialists can perform gap analysis of your current AV / EDR products to ensure all endpoints are protected.

    What We Know About The Microsoft Teams Phishing Campaign Pushing DarkGate Malware

    In a recent incident, security experts at Truesec noticed Microsoft Teams messages originating from third-party accounts, delivering ZIP files that purported to be from the victims HR department.

    Initially, the attack commenced with a social engineering tactic aimed at enticing the recipient to click on the .zip file, which contained an LNK (shortcut) file masquerading as a PDF document.

    Upon execution, this file triggered a VBScript that initiated the download of a payload utilizing curl.exe and harnessed AutoIT in conjunction with a compiled AutoIT script. The outcome of this process was the detection of the file as DarkGate Malware by VirusTotal.

    The malware supports a magnitude of malicious activities including remote access tooling, cryptocurrency mining, keylogging and a built-in stealer.

    Security Awareness in Microsoft Teams

    Microsoft Teams, by default, permits external third parties to engage in communication through its platform. While many training resources focus on email as a potential threat vector, it’s crucial to educate your user base about the risks associated with external communications in Teams as well.

    It’s worth noting that even with security measures like Microsoft Safe Links and Safe Attachments in place, they may not provide complete protection against all types of threats. As seen in the incident investigated by TrustSec, there can still be vulnerabilities and risks to address. Therefore, a multi-layered security approach that includes user awareness and training is essential to bolster your organization’s defense against evolving threats in platforms like Microsoft Teams.

    Emerging Phishing Threats: What’s The Impact?

    This particular phishing campaign is still in its early days.

    Given the limited range of mitigation methods currently available and the probability that users have not been adequately trained to recognise this specific threat vector, they may be more susceptible to this tactic compared to traditional email-based attacks.

    Solace Cyber Recommendations

    Educating staff about this specific threat vector is crucial. Prioritise raising awareness, similar to efforts against email phishing attacks.

    Given the restricted options for mitigation, it’s advisable to assess external messaging permissions. Administrators have the option to create an approved list of specific organisations allowed to communicate or, alternatively, block all third-party communications.

    Additionally, it’s essential to conduct a comprehensive gap analysis of your existing AV (Antivirus) and EDR (Endpoint Detection and Response) solutions to guarantee that all endpoints are equipped with functioning and current protection measures.

      Navigating the Crossroads: The Impact of Cyber Security Threats on the Automotive Industry

      In an era marked by rapid technological advancements, the automotive industry is undergoing a transformative shift. With the advent of connected vehicles, autonomous driving, and integrated smart systems, vehicles have evolved from mere mechanical machines to sophisticated computers on wheels. While this evolution brings remarkable benefits, it also introduces a new frontier of challenges, primarily in the realm of cyber security. This blog explores the growing influence of cyber security threats on the automotive industry and the measures being taken to address these challenges.

      The Rise of Connected Vehicles and Vulnerabilities

      Connected vehicles have become a symbol of convenience and innovation. However, the integration of internet connectivity into cars also presents a potential gateway for cyber attackers. Hackers can exploit vulnerabilities in infotainment systems, telematics, and communication protocols to gain unauthorised access to a vehicle’s network. This access could lead to unauthorised control over critical functions, jeopardising passenger safety.

      Autonomous Vehicles and Their Security Quandaries

      The pursuit of autonomous driving has further intensified the need for robust cyber security. Autonomous vehicles rely on an array of sensors, cameras, and data-sharing mechanisms to navigate roads safely. Any compromise in the integrity of these systems could result in accidents or even intentional harm. Protecting these vehicles from hacking attempts is crucial to ensure public trust and safety in this transformative technology.

      Data Privacy and User Information

      Connected vehicles generate an immense amount of data related to driving patterns, user preferences, and geolocation. This data is not only valuable for manufacturers but also for malicious actors seeking to exploit personal information for financial gain or other nefarious purposes. Ensuring the privacy of user data has become a significant concern, necessitating stringent data protection measures.

      Supply Chain Vulnerabilities

      The automotive industry relies on a complex global supply chain, which can inadvertently introduce vulnerabilities. If even a single component or software module is compromised at any point in the supply chain, it could potentially expose the entire vehicle fleet to cyber threats. Collaborative efforts between manufacturers and suppliers are essential to establish a chain of trust and enhance cyber security resilience.

      Industry Response and Collaborative Initiatives

      Recognising the severity of cyber security threats, the automotive industry has begun taking proactive measures. Collaboration between automakers, technology companies, and cyber security experts has led to the development of best practices, guidelines, and standards specifically tailored to the industry’s unique challenges. Organisations like the Automotive Information Sharing and Analysis Center (Auto-ISAC) have been established to facilitate information sharing and coordination among industry stakeholders.

      Integration of Security by Design

      To mitigate cyber security risks, manufacturers are increasingly adopting a “security by design” approach. This strategy involves integrating cyber security measures at every stage of a vehicle’s development lifecycle. From concept and design to manufacturing and maintenance, security considerations are embedded to create a holistic and robust cyber security framework.

      The Comprehensive Solace Cyber Solution

      As the automotive industry accelerates toward a future defined by connectivity and automation, the spectre of cyber security threats looms large. The intersection of technology and transportation has brought unprecedented conveniences and efficiencies, but it has also exposed vehicles to new forms of risk.

      Organisational compute and infrastructure, such as classic on-premises server rooms, datacentres and cloud-based services are all subject to regular attack and the colocation of many services, often with network cross over between, has simply increased the scope and availability of a reachable threat surface.

        Military Coup in Gabon August 2023

        Summary of Military Coup in Gabon

        In the early hours of 30 August, the Gabonese Election Centre (CGE) announced that President Ali Bongo had won a third term in office, having received 64.27 percent vote share in Saturday’s general election. However, just after 05:00 local time, a group of senior officers from the Gabonese military announced on television channel, Gabon 24, that they had seized power with the full support of the Gabonese security and defence forces.​

        Introducing themselves as members of The Committee of Transition and the Restoration of Institutions, the officials stated that the election results were cancelled, all borders were closed until further notice and state institutions – the government, the senate, the national assembly, the constitutional court and the election body – were dissolved. ​

        Following the announcement, domestic and regional sources reported gunfire could be heard in the capital Libreville. However, as the day progressed, the streets appeared calm, and crowds of  citizens peacefully took to the streets. Videos circulating on social media showed multiple instances of people celebrating and cheering, often in close proximity to the country’s armed forces. So far, there has been no signs of widespread protest or alarm. Several hours after the officers’ announcement, internet access also appeared to be restored for the first time since Saturday’s vote. ​

        The Gabonese government has yet to make an official statement, with President Bongo reportedly under house arrest, surrounded by his family and doctors.​

        Potential for Political Unrest in Gabon

        Ahead of the coup, there was significant concern over potential unrest following Saturday’s presidential, parliamentary and legislative elections that the opposition alleged were plagued by fraud. Questions over the election’s transparency were re-enforced by the lack of international observers, the suspension of foreign media broadcasts, the decision to cut internet service, and the imposing of a nationwide curfew.​

        President Ali Bongo and his father, Omar Bongo, have ruled Gabon since 1967, but frustrations with the political dynasty had been growing for several years ahead of Saturday’s election. The Central African nation is a major oil producer, so much so that it is a member of OPEC, as well as being a major exporter of uranium and magnesium. Indeed, the country is home to over one-quarter of the world’s proven magnesium reserves. However, Bongo has done little to channel its oil and other wealth towards the population of some 2.3 million people, a third of whom live in poverty. ​

        This is also not the first attempt in recent history to overthrow Bongo as in January 2019 he and the Gabonese government were able to foil an attempted military coup after soldiers briefly seized the state radio station and broadcasted a message saying Bongo, who had suffered a stroke months earlier, was no longer fit for office.

        Situation Analysis by Solace Global

        The strength of Gabon’s extractive-based economy means that it is Africa’s third most wealthy country by GDP per capita. However, with large swathes of the country still living in poverty, it is highly likely that the state has failed to transfer much of this wealth to ordinary citizens. It is likely that economic disparities have been one of the major triggers for the coup. This is likely supported by the lack of public resistance and the fact that celebrations have been seen on the streets of Libreville and other major population centres across the country.​

        Furthermore, the coup has yet to be characterised by anti-French rhetoric in a similar vein to the recent West and Central African coups in countries like Niger and Mali. However, the coup is almost certainly another problem for Paris in Africa, with multiple French companies operating in the country. Unlike the other coups in Africa, it is doubtful that the Gabonese coup leaders will seek Russian support in favour of maintaining Western relations. Gabon has traditionally had weak ties with Russia and unlike much of Africa, has not been threatened with major insurgencies and security issues. Moreover, Gabon was one of the countries in Africa that voted against Russia at the United Nations in the 2022 resolution on Ukraine.​

        Economically, the coup is almost certainly going to lead to price volatility in global oil and magnesium markets. Gabon has strong economic links with both France, and increasingly with China, and it is a major exporter of commodities to these nations. Reports indicate that some foreign companies like the French mining company, Eramet, have already suspended operations in Gabon in response to the coup. It is therefore highly likely that both France and China will be looking for the political situation to be resolved quickly, and there is a realistic possibility of diplomatic involvement from both Paris and Beijing. ​

        In the immediate future, it is unlikely that any major protests or armed clashes will break out as the Gabonese security forces are seemingly onside, and most indications suggest the public is too. The turning on of the internet was likely a move to win over the public as well as signal a different approach to governance than the Bongo regime. However, this also presents an increased potential for demonstrations and protests, both in favour and against the coup, to occur as information is spread on social media. There is a realistic possibility of sustained demonstrations which will likely lead to disruption in major population hubs. Borders will likely remain closed for upcoming days, but if scenes remain calm, borders are likely to reopen quicker than seen in Niger and Mali.

        Advice for travellers affected in Gabon

        • Although the coup appears to be relatively peaceful, widespread unrest and violence could ignite at any time. Travellers should avoid all ongoing military activity and any large public gatherings as the security situation may deteriorate quickly and without warning.​
        • In the event of significant security development, travellers in Gabon should follow any instructions issued by the government or military authorities. If a curfew is declared it is vital to abide by the curfew rules to avoid any conflicts with security forces.​
        • If violence escalates inside the capital, consider departing from Libreville whilst commercial options are still available. ​
        • Key military and political infrastructure inside the capital are very likely to remain focal points for violence and demonstrations. You should be particularly vigilant in these areas and follow any specific advice from the local security authorities.​
        • Expect significant travel disruption and an enhanced security force posture inside Libreville in the short-term. Should any opposition movement to the coup materialise, it is likely that flights will be suspended, and roadblocks or vehicle checkpoints will be established.​
        • Always follow all instructions and orders from security forces. ​Where possible, avoid areas of active conflict and remain inside a secure location away from windows. 
        • Ensure that you always carry personal identification documents. Consider making photocopies of important documents in case of confiscation, theft or loss and keep these documents separated from the originals.​​​
        • Emergency services may be unable to support you in the short-term. Be aware of what consular support may be available to you in-country. Many countries do not provide direct consular support in Gabon. The UK’s consular services for Gabon are based in Yaoundé, Cameroon.​
        • Have emergency contact numbers saved on your phone. These should include the local authorities, medical facilities and any consular support. Ensure that mobile phones are charged in case of any losses in electricity.​
        • If caught in the vicinity of a security incident, seek shelter immediately and leave the area if safe to do so. Continue to adhere to all instructions issued by authorities and obey any security cordons in place. ​
        • Monitor the Solace Secure platform and trusted local media for updates relevant to the coup. 

        Attempted coup in Niger July 2023

        Summary of Attempted Coup in Niger

        On the morning of 26 July, multiple domestic and regional sources reported that a potential coup was underway in Niamey, Niger. Early indications suggested that the Presidential Guard had blocked the entrance to the Presidential Palace, and detained President Mohamed Bazoum. Concurrently, government ministries next to the palace were blockaded, with those inside, including the Minister of the Interior, detained.

        By early afternoon, the Niger Armed Forces (FAN) and National Guard had both deployed in the vicinity of the Presidential Palace. The FAN and the Presidential office both released statements asserting that the ongoing coup attempt was being driven by “anti-republican” elements and gave the Presidential Guard an “ultimatum” to stand down and release President Bazoum, or face being attacked. Unverified social media reports have subsequently described armoured FAN columns entering Niamey. Further unverified reports later emerged of roadblocks appearing across the city.

        The conditions in Niamey remained calm initially, however, as the situation developed businesses were reputedly told to close and residents were ordered to stay at home. Operations at Diori Hamani International Airport currently remain unaffected, with flight tracking data showing that both inbound and outbound flights were operating as normal.

        Recent Instability in Western Africa

        Since 2020, several coups have taken place across the Sahel region, most notably in neighbouring Mali and Burkina Faso. The key driver for instability has been the inability of central governments to guarantee internal security from a myriad of insurgencies and terrorist actors. Niger has been increasingly afflicted by the instability affecting the wider region. In the southeast, Niger is battling incursions from Boko Haram and in the west of the country, the government is attempting to contain threats from Islamic State’s Sahel Province.
        Due to the external and internal threats posed by these actors, Niger has become a major operating base for Western nations in the region. Indeed, both France and the USA utilise the country as a base for operations in the wider Sahel.
        This relationship has grown in significance for Western governments as relations with other states in the region, such as Mali and Burkina Faso, have broken down in the wake of their own respective coups, leading to the expulsion of French forces.

        Further strengthening this relationship is the fact that Niger’s President was democratically elected in 2021 and is one of the region’s few remaining democratically elected heads of state. However, in February 2023 protests erupted in the capital, Niamey, with demonstrators expressing their dissatisfaction with a sustained French military presence in the country, with many believing that the foreign presence was either ineffective or had exacerbated security concerns.

        Situation Analysis by Solace Global

        At the time of writing, there has been no official statement from Presidential Guard. However, given the recent regional trends, it is highly likely that this attempted coup has transpired due to concerns regarding the deteriorating security of Niger.

        This is further evidenced by the fact that the Presidential Guard has also apprehended the Minister of the Interior, who is the person ultimately responsible for policing and internal security in Niger. The recent uptick in attacks near the borders with Burkina Faso and Mali likely provided the catalyst for the current situation.

        As the situation develops, it is almost certain that key transport routes and critical locations across Niamey will be seized by rival forces. This will include Niamey’s key river crossings, which connect the main part of the city on the eastern bank of the Niger River to its western parts, the international airport, and state TV and radio offices. At the time of writing, it is believed that President Mohamed Bazoum remains in detention.

        The success of the ongoing attempted coup remains to be seen. Initial signs suggest that the FAN and National Guard have remained loyal to President Bazoum and are willing to fight. If this remains the case, it is unlikely that the coup succeeds due to the disparity in military firepower between the two sides. This result would ultimately see the Presidential Guard purged.

        However, should the coup succeed, civil unrest, both in favour and against, will highly likely occur. A transitional military council will likely take over the government and immediately revise the stationing of foreign militaries in Niger. The removal of the last remaining Western forces in the region will likely create a security vacuum, that will almost certainly benefit the insurgencies and terrorist groups in Niger and the wider region.

            What we know about the MOVEit Transfer vulnerability

            The MOVEit transfer application used to transfer files has a zero-day vulnerability in the form of an SQL injection vulnerability. This in turn allows the adversary to drop a web shell on the host inside the MOVEit wwwroot directory. After which time, the attacker could then download any file within MOVEit and install a backdoor.

            A known breach involving Zellis, a supplier of IT services for payroll and human resources says a “small number” of organisations have been affected.

            The ransomware group “Cl0p” has posted on their ransomware site that they are exploiting the MOVEit vulnerability. Microsoft have also attributed the attack to Cl0p. The recent attacks do not show signs of encryption, although there is potential for this to occur as well as lateral spread.

            The group states on their Darknet page that they’ll post the names of the organisations compromised on June 14th 2023 if the targeted organisation hasn’t already contacted them. In the past 24 hours the BBC, Boots and British Airways have confirmed they’ve been impacted.

            The UK’s National Cyber Security Centre said it was “monitoring the situation” and urged organisations using the compromised software to carry out security updates. As of today, results from internet reconnaissance show that there are 127 instances in the UK of the MoveIT Transfer application and 1853 in the US.

            What’s the impact of the zero-day exploit?

            Due to the growing number of compromised organisations and the current supply chain spread the impact is still yet to be fully materialised.

            Organisations without the vendor’s latest patch against CVE-2023-34362 should assume breach and conduct investigative and remediation efforts where the service is publicly accessible.

            Solace Cyber recommendations

            Where applicable we recommend organisations:

            1. Disconnect MOVEit Transfer servers from the internet
            2. Search for indicators of compromise
            3. Rotate credentials for Azure storage keys / Rotate any other SQL credentials
            4. Perform a forensics investigation of your affected servers
            5. Restore and rebuild from a backup of the systems last known good state
            6. Apply the patch
            7. Continuously monitor all systems

              Microsoft Patch Tuesday and Apple.

              Apple has released an update relating to two actively exploited vulnerabilities. Microsoft has also released updates addressing 97 vulnerabilities including one 0-day.

              Threat Name: CVE-2023-28206,

              Risk Factor: Critical

              What we know about the vulnerabilities

              All in-support MacOS and iOS devices are affected by two vulnerabilities that are being actively exploited: CVE-2023-28206 and CVE-2023-28205.

              It’s recommended that you update systems ASAP as detailed instructions on how to abuse CVE-2023-28206 are now public.

              Microsoft has released a vast number of fixes this month. One vulnerability is a 0-day CVE-2023-28252 where there is known exploitation by Nokoyawa ransomware. Another noteworthy vulnerability is CVE-2023-21554, which is marked as critical and is a remote code execution vulnerability that affects Microsoft Message Queuing.

              Microsoft message queuing is commonly installed on exchange servers where automatic role installation is selected during install although this vulnerability is not limited to exchange only.

              CVE-2023-28220 and CVE-2023-28219 both affect Windows remote access servers (RAS) and have been marked by Microsoft as “exploitation more likely”. RAS servers are usually directly on the internet to provide remote access to an organisation.

              Lastly, a critical DHCP vulnerability was also fixed relating to CVE-2023-28231. This vulnerability would allow an attacker to craft an RPC call to the DHCP server to exploit this flaw. Commonly, DHCP services are installed alongside domain controllers, which is a known bad practice due to these types of DHCP flaws.

              All iOS and MacOS devices must be updated to the latest available versions, as CVE-2023-28206 and CVE-2023-28205 are actively being exploited.

              Due to the vast quantity of critical Microsoft vulnerabilities this month and the Microsoft 0-day it would be worth prioritising patches for external systems such as, Exchange and RAS servers first. Then, DHCP services and the rest of your fleet.

              It would be worth considering splitting out any known domain controllers with DHCP services going forward. Moving DHCP as a service to another machine.

              The Solace Cyber Implementation Plan

              Solace recommends:

              1. Immediately updating all Apple devices to the latest available versions to address CVE-2023-28206 and CVE-2023-28205.
              2. Prioritising the patching of external-facing systems, such as Exchange and RAS servers, due to the higher likelihood of exploitation.
              3. Updating all other Microsoft Operating systems.
              4. As a best practice, move DHCP services away from all domain controllers to another Server or appliance.
              5. Conducting a thorough vulnerability assessment to identify potential weaknesses and prioritise remediation efforts. Solace can provide additional assistance with vulnerability scanning.
              6. Due to the active exploitation of this month’s Apple vulnerabilities, Solace can provide a forensic mailbox investigation to look for signs of mailbox compromise.

                Zero Day Exploit

                Critical Vulnerability for Microsoft Outlook

                Microsoft Outlook has a critical vulnerability Critical 9.8 (CVSSv3) that requires zero interaction to be successful.

                Microsoft has released a patch for Outlook.

                Threat Name: CVE-2023-23397

                Risk Factor: Critical

                What we know so far about Microsoft Outlook zero day exploit

                The vulnerability has been exploited by the threat group APT28, also known as Fancy Bear, Sofacy, and STRONTIUM since April 2022.

                It was initially reported to Microsoft by the Ukrainian CERT. According to Microsoft, “a Russia-based threat actor” exploited the vulnerability in targeted attacks against several European organizations in government, transportation, energy, and military sectors.

                Currently 15 organisations are believed to have been targeted or breached using CVE-2023-23397.

                Solace Cyber Head of Incident Response believes with high certainty that this particular vulnerability will be used by other threat actors – equating to a vast quantity of attacks in the coming days to weeks.

                As of 16/03/2023 proof of concept code has been developed by security researchers and it is likely to be used in subsequent attacks by other threat actors.

                How Zero Day Exploit CVE-2023-23397 works

                The attack involves the attacker sending an Outlook note or task to the victim, triggering the notification sound file mechanism, which sends an NTLM negotiation request to the attacker-controlled SMB share. The threat actors accomplish this using extended MAPI properties that contain UNC paths. The vulnerability can be exploited with a simple, specially crafted email, even if the victim doesn’t open the item.

                However, it’s worth noting that this vulnerability cannot be exploited with Outlook for iOS, Mac, or Outlook for Android. Nevertheless, it affects all Windows versions of Outlook that are currently supported.  

                Who is at risk from the Microsoft Outlook Zero Day Vulnerability

                • Organisations that have on-premises domain controllers and use outlook.
                • Organisations that only use Azure AD only and have no on-premises domain controllers are protected.  

                Note: Those at a higher risk include remote workers due to home firewalls that do not block SMB traffic.

                Solace Cyber Recommendations to mitigate risk

                1. Immediately patch all Outlook clients to the latest available version (Microsoft released the required software update this Tuesday).

                This can be done by emailing all end users to advise a manual update of Microsoft Office (click-to-run) or updating via alternative methods. If you require assistance with auto-patching solace cyber can assist.

                • Launch any office application. Microsoft Outlook, Word, Excel or PowerPoint.
                • Select File > Office Account.
                • Update Options > Update Now.
                • Allow update process to complete (Approximate time to complete: < 15 mins)

                1. Additionally, organisations are strongly advised to run Microsoft’s script to look for signs of compromise in user’s mailboxes.

                Preferably this is run in audit mode only so that forensic data can be reviewed. If the script produces results it is recommended that you review the UNC paths in the outlook items to ensure no exploitation has occurred. 

                1. Ensure SMB outbound connections are blocked on your organisations firewall.
