Having a plan for how you will respond to common incidents is key. It’s a good idea to have procedural level “playbooks” (we used to just call these procedures, maybe I’m old!) but let’s get taktic00l and call them:
Playbooks/Runbooks/Aide-mémoire etc.
That aside (words are fun right!) they key part here is to identify the people, roles and responsibilities and the systems/actions/decisions you will need to take. To start with let’s look at a common incident of Phishing with credential harvesting, this may lead onto business email compromise (BEC) and attempted or successful fraud or downstream supply chain attacks.

There are tons of “products” for security awarenss training, however you might find that sitting and watching canned CBT videos isn’t your organisations thing or perhaps you want to see what other options there are available. Well for starts the UK NCSC has some free online security awarenss training (see further down the post), or you may want to actually spend time with your staff to make the learning a collaboarive experiance that drives engagement and communication. If the last one if your desired approach there are lots of ways to do this. One of which can be supported by a question based assessment, other ways include tabletop scenarios and incident simulations (i honestly would go with a blended appraoch if it was me!).
So to help people get thinking about this I’ve put together some example questions to drive the message about incident reporting, collaboration and education vs blame. So here we go, here’s some ideas for communication and some questions to get staff thinking about cyber security, sure they aren’t rocket science, but then it doesn’t need to be!

If you have a business email compromise incident and you haven’t deteced it in a timely manner your fist notification might be a bad experiance, the threat actors may have commited fraud, attemped fraud or simply launched a phishing If you have a business email compromise incident and you haven’t detected it in a timely manner your fist notification might be a bad experience, the threat actors may have committed fraud, attempted fraud, or simply launched a phishing campaign from your environment. If you are in this position, there are some steps you can take from a technical point of view to limit impact and reduce risk of a re-occurrence. This blog is a high-level view at some of the tactical and longer-term activities you can conduct.

This is part of a series I’m writing which is focusing on some of the core fundamentals of why cyber security is a business issue, why business leadership should care and invest in a good security posture and I’m looking at common security threats and ways you can combat these.

“Security education and awareness darling, it’s all the rage! It’s simply to hot right now.” Ok stop, let’s take a minute to get some context. It’s the year 2021, organisations are taking a battering round the globe from cyber criminals who are deploying ransomware, extortion, and fraud via a range of methods but one you can’t not have heard of is phishing.
In this post today, I’m going to look at realities of initial access, phishing and some questions I think people should be asking themselves about the idea of phishing their own userbase. I try and look at this from multiple perspectives because I think it’s a complex subject. Let’s start with initial access methods!
If we look at the world of technology and cyber security, you will see logs of references to frameworks and language that is enough to send even the committed to sleep! However, let’s abstract from our TTPs, our MITRE ATT&CK frameworks and our “threat actors” and let’s talk in normal English.

Did you ever just ignore or delete a phishing email? I mean that’s great in one sense that you won’t have any negative impact. But if the email did get past the mail security filters, you can report it using the “Mark as phishing” option.
What if as well you wanted to not only enable users to report but also pass the intelligence onto the NCSC Suspicious Email Reporting Service (SERS)? How cool would that be! Well, have no fear people, we are going to show you how easy this stuff is to deploy and configure. Read more “Reporting an email as phishing in Office 365 with NCSC SERS”

Business email compromise can be a prelude to a range of attacks but commonly it’s either Ransomware of Scammers. In this post we are focsing on scammer activity which uses a ‘man in the mailbox’ attack to get in between two parties in an email converstation with the aim of attempting theft by fradulently altering a wire transfer so that the third party sends funds to the scammers not to the victim. There are cleary other avenues that can be leveraged (the compromised mailbox may be used to phish or email malware to another victim).
To gain access to the mailbox a range of techniques can be employed which includes:
Once they have your logon credentials, they now will attempt to access your mailbox.
A scammer may use a public VPN service (such as services from AVAST etc.) to move their internet connection the target mailbox region. They can usually locate a person through some OSINT.
By moving to the normal area of the user they are less likely to trip geo location alerts. Read more “Business Email Compromise in Office 365”

Phishing is very likely the most common attack vector, in fact so common that the following stat is called out:
“a 2016 study reports that 91% of cyberattacks and the resulting data breach begin with a phishing email”
Setting up the Social Engineering toolkit or custom phishing solution takes a little time, luckily Microsoft have added in attack simulation features into Office 365! This let’s in house teams perform a range of simulated attacks in safe manner against your organisation. In this post we are going to run through the steps required to create and run a phishing attack simulation!
