The issues started at around 09:29 GMT and is affecting some users across Ireland, the UK and the rest of Europe. The Topsec Technical Support team have also started to notice that emails belonging to some of our customers who use Microsoft Office 365 were beginning to queue on our systems as they were temporarily undeliverable. These emails will queue on our systems for up to 5 days or until we can re-establish a connection with the delivery point (i.e. MO365), meaning none of our customers emails will be lost. This may not case for those who rely Microsoft Office 365 solely.
According to Wired, a massive database containing 772,904,991 unique email addresses and over 21 million unique passwords was recently posted to an online hacking forum. They suggest that the breach, called "Collection #1," doesn't originate from the one source but it is a collection of 2,000 leaked databases that included passwords which have since been cracked, meaning the protective layer that "hashes" a password to prevent it from being visible has been cracked to be presented in a usable form on the hacking forum.
Over the past 24 hours Topsec Engineers have noticed a massive spike in the number of the below Revenue Phishing emails which appears to come from revenue.ie. The email claims that the receiver is due a tax refund and must submit a Form 12 urgently. Conveniently, there is a “link” to the Form 12 in the email.
More and more organisations are starting to ensure that their employees use multifactor authentication (MFA) to add an extra layer of security to their Microsoft Office 365 and other accounts. Multifactor authentication and two-factor authentication involves using an extra step (like a phone number or verification code) in addition to your login credentials. This makes it harder for hackers to log in to your account if they have your username and password. It's a very useful additional security step, however security researchers say that it’s use isn’t very widespread.
Topsec engineers have noticed a disturbing trend in a certain type of email that we would classify as Social Engineering. While we have blocked a significant amount of these, some will always leak through spam filters.
Researchers have come across a security flaw in the way Office 365 email filters are designed to handle HTML code which has resulted in hackers getting malicious links into the mailboxes of end users. The hackers used an incredibly simple trick to get malicious URLs to bypass Office 365 mail filters, by splitting up the malicious links by using a <base> URL tag.
Microsoft Office 365 had an outage on Friday which left users without email throughout Europe, the US and the Asia-Pacific.

A red weather warning has only been issued on six occasions since the system was introduced in Ireland in 2013 – and only for rainstorms, never for snow until last week. The fact that there have been two red weather warnings in the past 4 months and only 4 in the previous 5 years is a worrying trend. With businesses closing for days at a time, they need to be more prepared for these adverse weather conditions.
