Hackers Are Targeting Microsoft Teams — Here’s What Business Owners Need to Know
TL;DR (AKA the short version)
Microsoft Teams has become the go-to tool for business communication and collaboration. But recently, Microsoft issued a warning: cybercriminals and even state-sponsored hackers are using Teams to break into companies.
At Single Point Security, we’re helping our clients stay protected by strengthening Teams settings, monitoring for suspicious activity, and keeping users aware of new threats.
How Hackers Are Using Teams
Hackers have found ways to use Teams’ normal features — like chat, calls, and file sharing — to trick employees and sneak into company systems. Because Teams is a trusted platform, it’s easy for people to assume messages are safe.
Here’s what they’re doing:
Pretending to be IT support or trusted vendors to convince employees to share passwords or click harmful links.
Sending fake messages, files, or meeting invites that install malware or ransomware.
Setting up fake Teams accounts that look like real businesses or departments.
Using stolen access to move through systems and steal data or demand ransom payments.
Some well-known hacker groups have already used Teams to carry out these types of attacks.
Why This Matters
Hackers are taking advantage of the fact that Teams is used by millions of people every day. Once they get in, they can steal company data, access financial systems, or shut down operations until a ransom is paid.
Even small and mid-sized businesses are being targeted — not just large corporations.
