If there are Samsung brand laptops running Windows in your organization, you need to be sure that they get updated with the patch that Samsung released on March 4 to fix a security flaw in their Samsung SW Update Tool 2.2.5.16. The most recent (patched) version of the tool is 2.2.7.20.
An unpatched tool could be exploited to conduct a man in the middle (MITM) attack on a wi-fi network or LAN, allowing the attacker to redirect web page requests and return malicious files.
