Microsoft is having a rough week with troubles including an Outlook.com bug that prevented some email users from searching their messages for several hours on Thursday, and a Teams flaw that allows people to send phishing emails and malware to other Teams users. While the Outlook.com bug borking users' email was certainly an annoying inconvenience, perhaps a bigger problem is the Teams weakness.

A member of U.S. Navy's red team has published a tool called TeamsPhisher that leverages an unresolved security issue in Microsoft Teams to bypass restrictions for incoming files from users outside of a targeted organization, the so-called external tenants. The tool exploits a problem highlighted last month by Max Corbridge and Tom Ellson of UK-based security services company Jumpsec, who explained how an attacker could easily go around Microsoft Teams' file-sending restraints to deliver malware from an external account.

As more businesses experience resource and cost constraints, 86% of MSPs and MSSPs customers are outsourcing their security needs to consolidate security tools, according to OpenText. "Staffing issues that have plagued the security industry for years are getting worse due to today's complex economic environment. As a result, already short-staffed teams must find creative ways to do more with less," says Geoff Bibby, SVP of Marketing and Strategy, OpenText Cybersecurity.

Security researchers have uncovered a bug that could allow attackers to deliver malware directly into employees' Microsoft Teams inbox. "Organisations that use Microsoft Teams inherit Microsoft's default configuration which allows users from outside of their organisation to reach out to their staff members," Jumpsec researcher Max Corbridge explained.

Network and IT admins have been dealing with ongoing Microsoft 365 issues this week, reporting that some end users cannot use Microsoft Outlook or other Microsoft 365 apps. The issues started Monday, with numerous admins contacting BleepingComputer to say that some of their users are experiencing disruptive issues in Microsoft Outlook, with the program not opening, freezing after opening, seeing delays in mail delivery, or errors saying there is no valid license associated with the user.

Security researchers have found a simple way to deliver malware to an organization with Microsoft Teams, despite restrictions in the application for files from external sources.With 280 million monthly active users, Microsoft Teams has been adopted by organizations as a communication and collaboration platform part of the Microsoft 365 cloud-based services.

Security leaders are recognizing that cloud and the way cloud security teams work today are becoming increasingly critical to business and IT operations, according to Trend Micro. As a result, cloud security and the foundational practices of their teams will be absorbed into the SOC to increase efficiencies in the coming years.

How do you ensure the right people have access to it? How do you share what you need with your clients securely? How do you find one password when there are over a hundred? All teams face these challenges when it comes to password sharing and collaboration. With multiple layers of security, it makes it easy for teams to securely manage passwords, reduce the risk of data breaches and comply with data protection regulations.

HackerOne published the results of its new study, which reveals that half of the organizations surveyed experienced increased cybersecurity vulnerabilities in the last year as they faced security budget cuts and layoffs. HackerOne's survey shows that economic reductions, such as budget cuts, layoffs and freezing new hires and investments, related to security are negatively impacting the ability to manage cybersecurity efficiently for 75% of the companies surveyed.
