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

Migrate SBS 2011 Standard to Windows Server 2016

Drawing1

Your trusty old SBS 2011 is finally being retired. It had a good run. It probably still works but you cant get the parts, and the cloud is so appealing and for whatever reason you have, you are putting in a new on premises DC.

Hey, you don’t have to justify it to me. Chances are you shipped Exchange off to the cloud long ago, your clients never really ‘got’ SharePoint and SQL was just used by the backup software and WSUS.

The only thing we want to migrate is Active Directory and File & Print services. 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.

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

Office 365 Email Password Reminder

powershell2xa4Regular readers will no doubt be aware of the script i wrote about two years ago to alert a user their password was about to expire. If not, just what exactly have you been doing with your time?

In any case, several people have asked me if it can be made to work with Office 365. Using 365 as the email relay to send the messages, was one thing, querying 365 for a users password expiry, was something else. Something which at the time i believe could not be done.

Given they constantly release new features and tweaks, i revisited it this week and found that actually it can now be done, with a few tweaks to the original script.
