One paragraph in the report’s introduction says it all. “Our findings confirm the concern held by many security practitioners: Security controls are not performing as expected.” Most attacks go undetected, unprevented and without staff being alerted. Here are the percentages from the report:

Teams Users Take Note: “Fake Microsoft Teams notification emails are hitting inboxes,” Zeljka Zorz, helpnetsecurity.com, May 4, 2020

A lot of our readers are Teams users, so we pass this along. Teams users are being targeted, and the emails are almost perfect forgeries. The fake login pages you go to are identical to legit Microsoft pages. As of May 1, Microsoft said 15,000 to 50,000 mailboxes had been attacked. If the attack succeeds, you give them your Teams credentials, and maybe a single sign-on.

Researchers at Check Point found that 75% of the mobile users at a large multinational conglomerate were infected with an improved version of the Cerberus spyware. As the Check Point researchers said, “This is the first time we have a reported incident of lateral movement inside a corporate network that utilizes the MDM server as a means of spreading.” Apparently, it was a targeted attack. The Check Point report is here. Cerberus has also gotten more nasty, it now has a keylogger that can capture all credentials. It has special routines to capture Google Authenticator information, install TeamViewer, and much more.
