As you may be aware, Apple launched iOS 11 last Tuesday, 19th September, 2017

However, there is a bug in the latest iOS which affects the native Apple Mail app (Mail.app) on your iPhone or iPad which will prevent you from sending or replying to emails.

You might see an error message that says "Cannot Send Mail. The message was rejected by the server."

This will affect you if your email account is hosted by Microsoft on Outlook.com or Office 365, or an Exchange Server 2016 running on Windows Server 2016 you will have this issue.

Although, Apple and Microsoft are trying to resolve this issue - there has been nothing released yet.

WHAT DO YOU DO?

You have these immediate options:

  1. Delay upgrading to iOS 11
  2. Too Late ?
    1. Install the Microsoft Outlook app from the app store (it doesn't have this issue)

OR

B. Rollback to a previous version of iOS

For many people out there the NBA Playoffs last week were a major affair. However, unlike the winning Cleveland Cavaliers the Milwaukee Bucks have long been a laughing stock on court. However, their most recent loss is no laughing matter. According to Yahoo! Sports, last month a team employee unknowingly sent out names, addresses, Social Security numbers, compensation information and dates of birth of players to a spoofed email account operated by a hacker. However, the Milwaukee Bucks were simply the latest victim in what is a threat to businesses of all sizes in all countries including Australia. We’ve come up with some pointers on how to protect your business from spoofed emails.

Education is key
There are countless cliches out there promoting the importance of education, but when it comes to cyber security, you might as well embrace them all. In the case of spoofed emails, you need to make sure your employees know what these are and how they can harm your company. They can come in several forms and look to attack your organisation in a number of different ways. A good defence starts with trained employees using best security practices when it comes to emails. Knowledge isn’t just the key to success, it’s the building block of a comprehensive email security plan.

Check the sender
The easiest way to determine a real email from a spoofed one is to view who is sending it. While your basic junk mail folder will screen the really lazy attempts at spoofing, you and your employees can’t rely on it to weed out everything. A lot of cybercriminals have gotten skilled at mimicking the look and feel of companies through professional looking graphics and signatures. For starters, you are going to want to ignore email display names as these can be deceptive. The domain name provides the best clues as to who the sender really is. For instance, if an email requesting your company’s financial documents claims to be from the ATO but the domain reads atogov.com, it’s a spoof email since that domain is not what the Australian Taxation Office uses. If you ever spot an email containing a domain you consider to be suspicious, delete it immediately. If it is from a legitimate sender, they will send you a follow up email in a couple of days.

Embrace DMARC
Domain-based Message Authentication, Reporting and Conformance (DMARC) can help reduce the risk of spoofed emails being sent internally. For businesses that do not set this up, it is possible for someone to spoof an email account that looks like it is from your business or a current employee and send it from a different server. As we saw in the case with the Milwaukee Bucks, these can appear legitimate to employees who will then in turn do what is requested such as turn off security settings or handover sensitive data. With DMARC in place you can prevent spoofed emails from utilising your domains by requiring any email sent by your domain to come from your server. This greatly reduces the risk of an internal spoofed email showing up in the inbox of your employees.

Utilise email protections
A lot of companies believe they can get by with the simple protections that come standard with an email client. However, doing the bare minimum is rarely enough to stop spoofed emails, not to mention all of the other threats lurking in your inbox, and high-powered email and spam protection will give your organisation the added layer of security it needs. Much like elite-level basketball players need the best coaching and equipment to succeed, the only way to truly reduce the risk of falling victim of a spoofed email is to educate your staff properly and then equip them with email filtering. This ensures they aren’t wasting their time constantly trying to identify legitimate emails from fake ones but are prepared when the situation presents itself.

When it comes to email security, working with us is a slam dunk. We may not have the skills of Andrew Bogut or the Australian rookie, Ben Simmons, on the basketball court but when in the realm of IT, competitors say they want to be like us.

Email Whitelisting

"Email Whitelisting" is a term used to describe the act of allowing an email to reach your inbox. This can be helpful if you want to make sure a sender doesn't go to your Spam folder.
