∗∗∗ The Life Cycle of a Breached Database ∗∗∗
---------------------------------------------
Every time there is another data breach, we are asked to change our password at the breached entity. But the reality is that in most cases by the time the victim organization discloses an incident publicly the information has already been harvested many times over by profit-seeking cybercriminals. Heres a closer look at what typically transpires in the weeks or months before an organization notifies its users about a breached database.

∗∗∗ Bear Tracks: Infrastructure Patterns Lead to More Than 30 Active APT29 C2 Servers ∗∗∗
---------------------------------------------
RiskIQs Team Atlas has uncovered still more infrastructure actively serving WellMess/WellMail. The timing here is notable. Only one month ago, the American and Russian heads of state held a summit wherein Russias aggressive cyber campaigns topped the list of President Bidens strategic concerns. Given this context, RiskIQ’s Team Atlas paid particular attention to APT around and after this summit, which took place on June 16.  This report will be of particular interest to those tracking APT29 and targets and victims of WellMess/WellMail, who may benefit from the tactical intelligence provided below.
