Spear Phishing: What Can you do?

I have seen a sharp rise in the number of spear phishing attempts my clients are subjected to. I’m sure this trend will continue. Of course our best line of defence when protecting our clients is user education. We can of course try and make things easier for them.

Our most recent example was quite lacklustre by comparison, they hadn’t even bothered to try and find a similar address, just some random Comcast account and setting the ‘From’ name to that of the Executive they were trying to impersonate.

I decided that to counter this we can tag the subject of any such email and then also generate an incident response within Office 365.

Using Office 365 to Protect Your Email

exchange-2014No doubt everyone reading this is familiar with spoofed email. Where an attacker crafts a message to appear as though it comes from a legitimate sender, in the hopes the recipient will reveal personal information or part with their hard earned cash.

With the rise in so called ‘spear phishing’, being able to effectively block spoofed email is no longer just desireable, it is critical.

Also bear in mind that whilst technologies like Sender ID and DKIM exist, they require both parties of an email to be using them for them to be effective.

You may think any domain you have moved to Office 365 recently is automatically protected by Exchange Online Protection however, like previous versions of Exchange, SenderID checking is disabled by default, as are advanced spam filtering and malware protection. Read more of this post

Manage Multiple Office 365 Tenants from PowerShell

o365-logo1Yep, another PowerShell themed post.

This is something I cobbled together a few years back, never thought it was worth sharing, but sitting here this evening with nothing much to do decided to write it up.

At it’s core it is not much more than a method of automating entering credentials to your various Office 365 ‘Clients’. I say ‘’clients” because I do not know if that is the correct terminology. If you are the Partner of Record or even if you are supporting more than one tenant on 365 this may be useful to you.

Outlook Office 365 System Folder Names appear with 1

RSS Feeds1After an Office 365 migration I had noticed I had some duplicate folders in my Outlook. The duplicate folder appeared with a 1 next to the folder name, and what’s worse it was on the ‘System Folders’ like Junk Mail or RSS Feeds.

you might be forgiven for thinking, so what? well indeed, but it was annoying the hell out of me and this is my website, so there you go..

I tried numerous times to remove them, or delete them, and replace them with new folders. Of course none of this worked. Read more of this post

Office 365 ProPlus 2016 CTR Deployment Tool Error 30029-1007

Office 365I had this problem today and i just couldn’t figure it out. Thankfully the issue was i was being an idiot which was my first thought, but you know, its good to confirm these things.

You may be setting up your clients networks to use the CTR Deployment Tool which was recommended to me by Guy Gregory after my last foray into Office 365 deployment.

If you haven’t used it before, then do check it out.

I edited the Configuration.XML file and i was convinced that was right, but immediately  i  would get an error on running setup.exe. Read more of this post

Quick Fix: Office 365 DirSync Hide a user from Global Address List

This week i have been working on some process automation, around a user leaving an organisation using Office 365.

DirSync (and it’s newer iterations) has been a very useful for Password Sync and User creation, however it can be a bit of a drag when it comes to editing mailbox settings. In this case, Hiding a user from the Global Address List.

Set-Mailbox Error On Prem

So to hide the Mailbox from our Office 365 Address List we need to use ADSIEdit and change the msExchHideFromAddressLists attribute to True, then wait for DirSync to do it’s thing. Read more of this post
