Don’t let down your guard yet, but it would seem that hackers are focusing their efforts on targets with deeper pockets than you or I. Sinclair Broadcasting is the latest infrastructure victim to have their operations significantly disrupted by a ransomware attack that took dozens of televisions stations completely offline for hours in various markets across the country. As one of the largest media companies in the US, Sinclair owns and operates nearly 300 stations in the US, and according to unverified reports from inside sources at Sinclair, many of the stations are connected via a common Active Directory structure that allowed attackers to jump from station to station, encrypting servers and paralyzing the the affected station’s ability to broadcast any of its regularly scheduled programming.
What this means for you
Sinclair doesn’t own any stations local to Southern California as far as I can tell, so most of us probably went about our weekend blissfully unaware that a ransomware attack locked down an undisclosed number of stations. Though they as of yet have not released specifics, it’s possible they are the latest victims to run afoul of a new RaaS (Ransomware as a service) called BlackMatter which, perhaps not coincidentally, has also shown up in a new advisory from CISA, the FBI and the NSA that warns of threat actors using the new platform to target critical infrastructure, including two recent attacks on agricultural targets in the US. While these attacks may not impact you or I directly, infrastructure attacks are definitely worthy of our attention as they can and will cause widespread disruption to activities and services we take for granted, and in some cases like hospitals or law enforcement agencies could actually be life-threatening. And here’s something you may not have considered – each of these attacks most likely started with and individual getting tricked into giving up a password that gives the hackers a toehold, and that is all they need. Unfortunately, in this increasingly complicated technology landscape it is becoming ever more difficult to keep passwords safe, mainly because we are always being asked for them. How many times a day are you confronted with a password request that makes you question it’s legitimacy? It’s a challenge to keep up with technology on a good day, but when the hackers have you on guard 24/7, you really can’t afford to not pay close attention.
Unfortunately, there isn’t any silver bullet or magical tip I can provide to help you here. It’s most important to know where and when a service might ask for a password, and how to recognize legitimate requests based upon having more than just a passing familiarity with applications and services that require passwords that protect sensitive data or privileged access. If anything, err on the side of not entering a password if you aren’t 100% certain. Additional protection will come from using multi-factor wherever it is made available to you, and of course, using unique, hard to guess passwords for all your important services.
