business π¨ Teams vishing attack lets hackers into company networks
A coordinated voice-phishing campaign called Spring Ring abused Microsoft Teams using fake IT support accounts. This attack targeted over 150 employees across more than 10 companies between January and April 2026. Attackers used convincing names and deployed two methods to gain network access. One method involved remote software, while the other used cloud storage links triggering browser hijacking. Organizations need better user education against unsolicited external communications.
