Microsoft today released updates to plug more than 80 security holes in its Windows operating systems and other software, including one that is actively being exploited and another which was disclosed prior to today.

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.

For those trying to draw meaning from the experience, might I suggest consulting the literary classic Moby Dick, which simultaneously holds clues about QAnon’s origins and offers an apt allegory about a modern-day Captain Ahab and his ill-fated obsessions.

In October 2020, KrebsOnSecurity looked at how a web of sites connected to conspiracy theory movements QAnon and 8chan were being kept online by DDoS-Guard, a dodgy Russian firm that also hosts the official site for the terrorist group Hamas.

U.S. government cybersecurity agencies warned this week that the attackers behind the widespread hacking spree stemming from the compromise at network software firm SolarWinds used weaknesses in other, non-SolarWinds products to attack high-value targets.

December 16, 2020

A key malicious domain name used to control potentially thousands of computer systems compromised via the months-long breach at network monitoring software vendor SolarWinds was commandeered by security experts and used as a “killswitch” designed to turn the sprawling cybercrime operation against itself, KrebsOnSecurity has learned.

December 15, 2020

The still-unfolding breach at network management software firm SolarWinds may have resulted in malicious code being pushed to nearly 18,000 customers, the company said in a legal filing on Monday. Meanwhile, Microsoft should soon have some idea which and how many SolarWinds customers were affected, as it recently took possession of a key domain name used by the intruders to control infected systems.
