Conti Ransom Gang Starts Selling Access to Victims

October 25, 2021

New research into the malware that set the stage for the megabreach at IT vendor SolarWinds shows the perpetrators spent months inside the company’s software development labs honing their attack before inserting malicious code into updates that SolarWinds then shipped to thousands of customers. More worrisome, the research suggests the insidious methods used by the intruders to subvert the company’s software development pipeline could be repurposed against many other major software providers.

The Joys of Owning an ‘OG’ Email Account

September 2, 2020

When you own a short email address at a popular email provider, you are bound to get gobs of spam, and more than a few alerts about random people trying to seize control over the account. If your account name is short and desirable enough, this kind of activity can make the account less reliable for day-to-day communications because it tends to bury emails you do want to receive.

U.S. Govt. Makes it Harder to Get .Gov Domains

March 7, 2020

The federal agency in charge of issuing .gov domain names is enacting new requirements for validating the identity of people requesting them. The additional measures come less than four months after KrebsOnSecurity published research suggesting it was relatively easy for just about anyone to get their very own .gov domain.

In November’s piece It’s Way Too Easy to Get a .gov Domain Name, an anonymous source detailed how he obtained one by impersonating an official at a small town in Rhode Island that didn’t already have its own .gov.
