s[.]teams-jk[.]com

This domain, s.teams-jk.com, is identified as a phishing site designed to impersonate Microsoft Teams login pages. The intent is to deceive users into entering their credentials, which are then captured by threat actors for unauthorized access to corporate or personal accounts. Such attacks often target remote workers, enterprise employees, or individuals using collaboration platforms, leading to data breaches, account takeovers, or further malicious activity like internal phishing or malware distribution. Analysis indicates this domain was registered on June 15, 2026, through REG.RU LLC, a registrar frequently associated with low-reputation or malicious domains. It resolves to the IP address 104.21.34.6, a Cloudflare-hosted endpoint often used to mask the true origin of phishing infrastructure. The site is flagged by 19 out of 95 security vendors on VirusTotal, and it appears on at least one security blocklist. The SSL certificate, issued by Let's Encrypt, provides encryption but does not validate legitimacy, as phishing sites commonly use free certificates to appear trustworthy. The page title, 'Our website is coming soon,' suggests the site may still be under development or configured to evade detection while awaiting deployment of the full phishing kit. If a user has visited s.teams-jk.com or entered credentials on this site, immediate action is required. First, reset the password for any accounts accessed or entered on the site, using a strong, unique password and enabling multi-factor authentication where available. Review account activity for unauthorized logins or changes, and report the incident to the organization's IT or security team if the account is work-related. Monitor for signs of identity theft or follow-up attacks, such as unexpected password reset emails or suspicious messages from contacts. Users should also clear browser cache and cookies to remove any stored session data, and consider running a full antivirus scan to detect potential malware. Organizations should block the domain and IP at the network level to prevent further access.
