Microsoft Finally Makes Sending From Email Aliases a Real Exchange Online Feature

October 7, 2026 by Edward Silha

This is one of those Microsoft 365 features that makes you wonder why it took this long.

Microsoft has finally moved Send From Alias in Exchange Online to general availability. The feature lets you send an email using any SMTP alias assigned to your mailbox, and the recipient actually sees that alias as the sender.

Seems pretty obvious, right?

For years, Exchange aliases were basically a one-way street. You could have sales@company.com, info@company.com, and yourname@company.com all assigned to the same mailbox and receive mail at every one of them.

But sending from one of those aliases was another story. [Read more…]

We Finally Got Everyone Using MFA. Now It’s Changing

October 2, 2026 by Edward Silha

For years, the security advice was simple: turn on multifactor authentication.

IT people repeated it endlessly. Microsoft pushed it. Insurance companies started requiring it. Cybersecurity audits looked for it. Eventually, most businesses got the message.

Users learned the routine. Enter the password. Wait for the text message. Type in the 6-digit code. Get back to work.

Now Microsoft is changing all of that. [Read more…]

Hackers Are Now Using Microsoft Teams to Break Into Corporate Networks

May 14, 2026 by Edward Silha

For years, companies drilled one thing into employees’ heads: don’t trust weird emails. Problem is, attackers adapted. Instead of fighting against people’s skepticism around email, they moved to platforms employees already trust without thinking twice about it. One of the biggest targets right now is Microsoft Teams

A threat group called KongTuke has been using Teams chats to get inside corporate networks, and honestly, it’s working disturbingly well. Instead of blasting out phishing emails, they pose as internal IT staff and message employees directly through Teams. Sometimes they’re operating from already-compromised Microsoft 365 accounts. Other times they create fake accounts designed to look close enough to pass a quick glance. Either way, the attack can go from first contact to compromised system in just a few minutes. [Read more…]

Hackers Pose as IT Support to Breach Salesforce, Steal Corporate Data, and Demand Ransom

June 4, 2025 by Edward Silha

Hackers posing as IT support are targeting employees at large companies to sneak into their Salesforce systems and steal data. They start with a phone call, pretending to help with a routine issue. The real goal? To get the employee to connect to a fake version of Salesforce’s Data Loader tool. Once that happens, the attackers can quietly grab sensitive company data.

Google’s Threat Intelligence Group has been tracking the group behind this, known as UNC6040. Their method depends on trust—posing as helpful support staff and guiding employees through what feels like a normal setup process. Because the tool is something many employees already use, it doesn’t seem suspicious. [Read more…]

Microsoft Extends Office Security Updates on Windows 10 Through 2028

May 18, 2025 by Edward Silha

Microsoft will continue rolling out security updates for Microsoft 365 apps on Windows 10 until October 2028, extending support three years past the operating system’s planned end-of-life.

The change follows the company’s earlier position, announced in January, that Office apps would stop receiving updates on Windows 10 starting in October 2025. At the time, Microsoft urged users to upgrade to Windows 11 to maintain access to updated versions of Word, Excel, and other Microsoft 365 tools.
