The CrowdStrike Outage and Market-Driven Brittleness

Friday’s massive internet outage, caused by a mid-sized tech company called CrowdStrike, disrupted major airlines, hospitals, and banks. Nearly 7,000 flights were canceled. It took down 911 systems and factories, courthouses, and television stations. Tallying the total cost will take time. The outage affected more than 8.5 million Windows computers, and the cost will surely be in the billions of dollars­—easily matching the most costly previous cyberattacks, such as NotPetya.

The catastrophe is yet another reminder of how brittle global internet infrastructure is. It’s complex, deeply interconnected, and filled with single points of failure. As we experienced last week, a single problem in a small piece of software can take large swaths of the internet and global economy offline…

Microsoft and Security Incentives

Former senior White House cyber policy director A. J. Grotto talks about the economic incentives for companies to improve their security—in particular, Microsoft:

Grotto told us Microsoft had to be “dragged kicking and screaming” to provide logging capabilities to the government by default, and given the fact the mega-corp banked around $20 billion in revenue from security services last year, the concession was minimal at best.

[…]

“The government needs to focus on encouraging and catalyzing competition,” Grotto said. He believes it also needs to publicly scrutinize Microsoft and make sure everyone knows when it messes up…

On Vulnerability-Adjacent Vulnerabilities

At the virtual Enigma Conference, Google’s Project Zero’s Maggie Stone gave a talk about zero-day exploits in the wild. In it, she talked about how often vendors fix vulnerabilities only to have the attackers tweak their exploits to work again. From a MIT Technology Review article:

Soon after they were spotted, the researchers saw one exploit being used in the wild. Microsoft issued a patch and fixed the flaw, sort of. In September 2019, another similar vulnerability was found being exploited by the same hacking group.

More discoveries in November 2019, January 2020, and April 2020 added up to at least five zero-day vulnerabilities being exploited from the same bug class in short order. Microsoft issued multiple security updates: some failed to actually fix the vulnerability being targeted, while others required only slight changes that required just a line or two to change in the hacker’s code to make the exploit work again…

Programmers Who Don’t Understand Security Are Poor at Security

A university study confirmed the obvious: if you pay a random bunch of freelance programmers a small amount of money to write security software, they’re not going to do a very good job at it. In an experiment that involved 43 programmers hired via the … Continue reading Programmers Who Don’t Understand Security Are Poor at Security

Programmers Who Don’t Understand Security Are Poor at Security

A university study confirmed the obvious: if you pay a random bunch of freelance programmers a small amount of money to write security software, they’re not going to do a very good job at it. In an experiment that involved 43 programmers hired via the Freelancer.com platform, University of Bonn academics have discovered that developers tend to take the easy… Continue reading Programmers Who Don’t Understand Security Are Poor at Security
