Emotet Returns

Emotet Trojan


Since its initial discovery in 2014, the Emotet trojan has become an increasingly dangerous and persistent threat to users and organisations across the globe. The US Department of Homeland Security CISA division, refers to emotet as ‘among the most costly and destructive malware’ affecting from small to large scale organisations of both the private and public sectors.

Emotet started out as a way to steal users banking details, the scope and capabilities of this trojan have changed drastically.

From spreading itself across a network infecting other machines to skimming Outlook contact information to use in spear phishing attacks to stealing browser history, user credentials and installing other malware such as backdoors and ransomware, emotet can be extremely damaging to an organisation. Also, due to Emotet being polymorphic and able to constantly change and modify itself, it is increasingly difficult to detect and prevent against using typical signature-based methods with hundreds of unique payload variants discovered daily.

Phishing Email Example

Phishing Email Example

Emotet trojans will generally arrive on a user’s machine via emails like the above example. Spam emails spoofing common brands and institutions (banks, government departments) with layouts and language designed to encourage the user to click on the malicious attachment or link to sites hosting the document for download.

Crimeware-as-a-service (CaaS) helps ensure that new versions of these email attachments can be generated and distributed on a near constant basis ensuring its ability to evade traditional AV on Zero-day.

We regularly see new Emotet detections and an example of a malicious emotet attachment that one of our agents detected had been created only 4 hours prior.

VT History

In a short span of time, a new .doc attachment was generated with a new file hash value which would be unknown to a traditional AV solution was attached and emailed to an unsuspecting user ready for the morning inbox clear-out.

At the time of the detection, our threat researcher uploaded a copy of the threat file to VirusTotal where only 8 other Vendors were aware of and had the file marked as malicious.

VT Detections

This means that on many other AV solutions, the file would have been allowed to run and would not have been detected.

For this example, the user clicks on the attachment unaware as the document starts delivery of the Emotet payload.

From the attack storyline on our management console, we can see that as soon as the doc is opened, it attempts to utilise PowerShell to run obfuscated code. Code obfuscation is one of the methods used by hackers to evade static analysis engines in Anti-Virus and help disguise their activity.

Story Line

In this case, the PowerShell code attempts to create a network connection to reach out to a compromised domain online and download the additional emotet payload to the users’ machine to exploit further.

For any business, such an attack could cause severe consequences that would translate to high financial costs and reputational damage.

In this case, the threat was detected by the behavioural engine of the agent which was able to determine that the activity exhibited by the threat was malicious and then, autonomously killed and quarantined the threat from the users’ machine. After the threat was investigated by our security analysts, the threat was successfully remediated against without any disruption or compromise to the user’s machine.

Without our agent in place on the user’s machine, the result may not have been as favourable.

5 Things Everyone Gets Wrong About Anti-Virus

It shouldn’t be news to anyone that cyber threats are on the increase, and the requirement to have an effective security solution has never been more pressing as advanced hacking techniques continue to proliferate in the wild.

With the market awash with vendors making bold claims and news stories making even bolder headlines, it can be hard to separate the fact from the fiction. If you’re new to endpoint security, here’s the five basic things to ensure that you get right about the options available.

1. Viruses Aren’t the Only Threat

Security threats have evolved beyond all recognition from the early days of the computer virus, but most security solutions still carry the term “anti-virus” in their name, which is really something of a misnomer in the modern threatscape.

The reality is that cyber attacks take many different forms that have nothing to do with being a virus, and they can range from the indiscriminate to the highly targeted. These include ransomware, spear-phishing, drive-by attacks and both software and hardware vulnerabilities that can lead to loss of customer and corporate data.

And don’t fall into the trap of thinking your business is too small to be targeted. Attackers are now weaponizing machine learning to produce highly-targeted campaigns, at low cost to themselves.

Also, don’t forget that threats can come from within; disgruntled employees know the weaknesses of your system better than any outsider. Good endpoint security needs to be able to detect bad behaviour no matter the point of origin.

2. Malicious Files Aren’t the Whole Story

Most people think that security software works by scanning files on the local computer and deciding whether they are malicious or not. Like the term ‘anti-virus’, that’s a bit of an old-fashioned way of thinking about it. Although there are still legacy AV programs that primarily work in that way, even they will usually offer some additional functions such as blocking malicious websites or detecting excessive use of resources typically used by ransomware and crypto-miners.

However, for truly effective protection, you should be looking at security solutions that do more than that. Today’s cyber criminals are able to leverage fileless attacks, change DNS settings to re-route your network traffic and inject code into legitimate processes. A legacy AV solution that primarily focuses on scanning for malicious files is, like last week’s soup, well past its sell-by-date.

3. Trust is a System Weak Point

As we hinted in the previous point, untrusted software is not the only danger on your endpoint. Even first-party and established software brands can be leveraged to breach your system.

While MS Office Macro attacks have a long history, Macro-less attacks such as DDE can exploit vulnerabilities that will bypass many security solutions because they appear to be coming from trusted applications. Similarly, most businesses will likely have a need for legitimate PowerShell operations, and yet PowerShell-powered attacks are becoming increasingly common. You need a security solution that’s smart enough to allow PowerShell to maintain your productivity, but also able to ensure that it can tell the difference between malicious and legitimate behaviour.

Modern malware can also run without interference on many systems running AV solutions if it is able to operate with system-level privileges, whether through a privilege escalation vulnerability or other methods of infection. This is because many AV packages take the wrong approach by granting trust by identity, rather than by behaviour. When security solutions take this kind of “whitelisting” approach, the endpoint is left vulnerable to supply chain attacks and fake certificates.

4. There’s Power in Simplicity

Security software doesn’t have to be hard to use, and you shouldn’t have to be a security expert to manage it. Unfortunately, a lot of security software gives business owners just that impression, overcomplicating things with diagnostic tools and components that require specialist training courses to master. Be sure to choose an endpoint solution that minimizes maintenance tasks, presents a clean, easy-to-understand interface and provides one-click remediation.

You want a solution that anyone in your team can quickly learn and operate. It’s important for business continuity that knowledge of your security solution is not tied to specially-trained members of staff. Who knows how long before they move on, taking their expert knowledge of your security solution with them?

5. Security is a Mindset, Not a Product

Probably the biggest thing you can get wrong about AV software is believing that it can solve all your security issues in one fell swoop. Threats come in many shapes and forms: from indiscriminate ransomware attacks to disgruntled employees. What’s your plan of action when (don’t think “if”) a breach occurs? How will you respond? Failure to have a response plan in place could mean greater damage to your customers, your data and your reputation.

This is why you need an endpoint solution that can be part of your entire response plan. A cross-platform solution like SentinelOne can provide deep visibility into even encrypted traffic across your network,  one-click remediation and rollback, and a single, holistic agent that’s simple to use.

Our Takeaway

Ignore the stereotype of sophisticated cybercriminals targeting billion-dollar businesses. Most attacks are opportunistic and target not the wealthy or famous, but the unprepared. According to a 2018 SentinelOne survey of US companies, 56 percent suffered a ransomware attack in the last year. Given that the majority of organisations will be hacked over their lifetime, it is imperative that organisations have the necessary tools to spot and stop an attack quickly and effectively.

This is why you need an endpoint solution that can be part of your entire response plan. A cross-platform solution like SentinelOne, provided by Custodian360 can provide deep visibility into even encrypted traffic across your network, one-click remediation and rollback, and a single, holistic agent that’s simple to use.

Lanning Consulting Company Choose Custodian360

I first met Custodian360 at an exhibition and was immediately impressed by their Managed Security Service offering.


A true Enterprise solution at SME prices.


Since that time, they have continued to be open, and approachable to support me as a reseller (with online demo’s, support at exhibition’s, addressing technical questions etc), but they are also more than willing to engage directly with customers on my behalf in the pre-sales cycles.


Their pricing model is clear and simple for partners allowing me to quote prospective customers instantly and avoid delays in my sales cycle.


My customers are always amazed at how quickly and easily Custodian360 detects threats that they didn’t know they already had in their networks.


Depositit Choose Custodian360

As a company offering Data Protection services to the SME sector we were seeking additional and complimentary solutions without the need for ourselves to spend time and resource reinventing the wheel.

We narrowed down our search of possible solutions and then emailed/left message and spoke/met with with the companies who, on the face of it looked like they could provide what we required. Very quickly we got a feel for the types of company we had approached as most didn’t return calls, those that did promised a call back which, to this day remains elusive and a few whom we met didn’t seem interested in doing business unless there was a guaranteed value on the table.

Custodian 360 were easy to contact, forthcoming and supportive in helping us achieve what we were looking to do and no question was too silly. They actually reminded us of us, which is very customer focused be it towards partners or an end user of the product itself. We knew within a very short space of time that this was a company we could develop a sound relationship with moving forward knowing we’d be supported in all ways.

The relationship continues to develop and grow and we feel  very comfortable approaching Custodian 360 at any time for resources, information, customer support, trial accounts, webinars and brainstorm sessions to develop ideas to help achieve sales.

We’re very happy with the choice we made and confident the relationship will only continue to prosper over the months and years ahead.

Trickbot Trojan On The Rise

Over the last month, we’ve noticed an increased amount of weaponised trojan documents detected by our Custodian360 agent.

Criminals have setup a large variety of fake email campaigns spoofing email domains to imitate genuine emails typically from financial institutions such as PayPal, HMRC, Sage, Barclays etc.  They typically use language which demand the user’s attention such as an “unpaid invoice” or “bill attached” and have a weaponised document attached for the user to open.

i Example of spoof email (Screenshot taken myonlinesecurity.co.uk)

Once opened, the threat will attempt to use exploits and vulnerabilities in Office to gain ability to create system process and download additional malicious payloads all without the users’ knowledge.

Whilst newer versions of Office have additional protections and countermeasures against this type of attach, many businesses still run older versions of Office. In a 2017 survey by Spiceworks, 68% of companies are still running instances of Office 2007 which won’t have sufficient protective measures in place against this type of threat.

Custodian360 effectively protects against this type of threat by using documents and scripts analysis engine to prevent their execution including unknown zero-day campaigns.

However, end users should still be advised to be vigilant and avoid opening unknown attachments and companies should be encouraged to move away from using older versions of office due to the vulnerabilities and increased security risk which these types of threats attempt to exploit.

Thomsonlocal Choose Custodian360

Thomsonlocal is one of the largest digital marketing agencies in the UK with over 30 years of experience connecting 10s of millions of customers and suppliers daily.

The security team at Thomsonlocal decided to work closely with AVR International to evaluate their options around End Point Security as the assessment had been made internally that ‘legacy’ systems were fast becoming unfit for purpose. “There are a plethora of End Point solutions in the market place currently and we simply don’t have time to test them all thoroughly.

We trust the technical capabilities of the AVR team and trusted that they would put forward only the very best solutions to address the changing needs of our business in the digital age.” Says Steven Denver (Infrastructure Support)

Key to the implementation were:

•A Modern approach to Protection, Detection and Remediation

•Detections rates – The existing solution was missing growing numbers of threats

•Detection methods – Signature scanning is fast becoming old hat and does not detect new advanced threats like memory based exploits.

•Comprehensive expert support with leading SLA times.

Following this collaborative approach Thomsonlocal chose Custodian360 as their New Managed End Point Protection Service. Built on the SentinelOne platform and managed by the team of experts at Custodian360 it is a service that backs itself 100%. Custodian360 offers SentinelOne’s unmatched detection, mitigation and remediation capabilities in one single agent all backed up by the Custodian360 teams’ many years of experience in EndPoint protection

“Custodian360 provides us with a truly next generation EndPoint solution which saves us time, money and most importantly protects robustly from Ransomware and all methods of threat” 

“I would highly recommend Custodian360 to address your EndPoint protection and remediation needs. The roll back functionality is exceptional and the level of support from Andy and the team from pre-deployment right through to production has been excellent”

Gartner’s New Buzzword

Gartner have a new buzzword, Endpoint Detection and Response (EDR). We want you to find the solutions that enable you to deliver it and deliver it profitably!

EDR – is the acronym for Endpoint Detection and Response which is one of the hottest topics for 2018 in the industry. 2017 saw the real emergence of EDR but 2018 is shaping up to dwarf last year.

Industry analyst Gartner, spawned the concept in 2013 has concluded that a more proactive approach is now needed, no longer can we simply attempt to block attacks, we must provide early and effective detection to minimise dwell time and damage and quite simply, this is what EDR provides.

EDR allows service providers, resellers and IT companies to climb the value chain by adding this solution to their portfolio and providing a valuable new layer of protection to customers’ security infrastructure.

All of this is great, but it only works of your chosen EDR is rapid to deploy, easy to use and manage and most importantly, profitable.

How do you make EDR profitable?

Complexity jumps straight out as a consideration; most solutions require multiple agents, and this adds a huge overhead into your management of the solution on your customers behalf. If they are managing themselves then it’s likely they won’t have the resource need to manage to solution.

Most EDR solutions, because of the way that they work are very “noisy”, huge amounts of alerts are generated, and these then have to be sifted through by a human. As has always been the case with other ground-breaking solutions, this makes them useless because of the time it takes to get to the right alerts.

It sounds as though all we are offering here is a complex and noisy solution. Unless this becomes a tick box on a compliance form will it ever offer value to you or your customers?

It’s a simple answer, and that answer is yes. Many new players are releasing their versions of EDR but the market leader is still SentinelOne and as their MSSP Partner Custodian360 simplifies the solution even more.

Custodian360: Giving you the tools and resource to provide value

Custodian360 is the only way to obtain SentinelOne as a fully managed service.

What does this mean for you? It means you can deploy the market leading EDR solution to your customers with no need to “skill up” or recruit new staff to manage a deluge of alerts every day or setup your own SOC to manage operations. Once the single agent is deployed, your job is done and Custodian360 take over operations entirely.

There are a number of features that Custodian360 provide and some of these are critical elements in any EDR solution:

  1. Rapid Deployment – Cloud Based Console up and running in minutes.
  2. Simple – There is only one agent, not many.
  3. Ease of use – A single console shows you everything you need to know.
  4. Automated Mitigation and Remediation – No need for you to manually intervene. Our analysts do that for you and remediate threats whenever necessary ensuring downtime is kept to an absolute minimum.
  5. Compatibility – Works with all Operating Systems and can co-exist with existing AV solutions.
  6. Artificial Intelligence and Machine Learning – Enables the agent to learn to identify false positives to reduce alerts and focus is given to real and dangerous threats.
  7. Automated Reporting and Alerting – Configure once and receive your reports monthly or weekly along with notifications of all alerts if required.

But do customers even want EDR?

I don’t think we’d be exaggerating if we said that customers’ demand for EDR is about to go stratospheric.

An EDR article in eSecurity Planet describes the growth in EDR as “explosive” and they report that Gartner’s forecast “is for almost 50% annual growth for EDR at least through 2020, putting it way out in front of most areas of IT”.

From this it’s a small step to work out the market value, again, according to Gartner’s EDR Estimates of some $1.5 billion – very likely when you consider that out of some 711 million devices that can make use of EDR, only 40 million currently do!

“Alert Fatigue” is already a well used term but a recent global EDR survey found that 72% of respondents report that their teams already suffer “alert fatigue” so if you can take away that fatigue for them and provide an effective and market leading solution, you can see why they will want to buy.

The message from the market is clear: for service providers, resellers and other IT partners, EDR is a revenue boost waiting to happen.

Just make sure you choose to sell solutions that are actually usable!
