Want to Stop Ransomware Attacks? Ban Bitcoin and Other Cryptocurrencies.
June 2, 2021 | Jacob Silverman, The New Republic

With conventional banking off-limits, “the ransomware problem is a Bitcoin problem,” wrote Nicholas Weaver, who researches computer security at the International Computer Science Institute. And a full ban may not ultimately be necessary.

Hacker Lexicon: What Is a Supply Chain Attack?

"Supply chain attacks are scary because they're really hard to deal with, and because they make it clear you're trusting a whole ecology," says Nick Weaver, a security researcher at UC Berkeley's International Computer Science Institute. "You're trusting every vendor whose code is on your machine, and you're trusting every vendor's vendor."

The experts on the panel — Angela Campbell, a Georgetown Law professor; Serge Egelman, a research director at UC Berkeley; and Beeban Kidron, founder and chair of 5Rights Foundation — also all testified in opposition to Instagram launching a platform for kids.

"It seems like overkill," Nicholas Weaver, a senior researcher at the International Computer Science Institute at UC Berkeley, told Motherboard in an online chat. "For most of these devices a choice of 'Either give us the password or rot in jail for contempt' might be sufficient."

“One of the problems is that there have been a lot of advances in security—good advances aimed at protecting users—that make it a lot harder to intercept the traffic, which at the same time we need to do to see what’s in it,” said [Serge] Egelman.

“This fix is a one-line thing where you remove a line that logs sensitive information to the system log. It doesn’t impact the program, it doesn’t change how it works, ” said Joel Reardon.

The problem is an implementation issue and not inherent to the exposure notification framework, Serge Egelman, the chief technology officer at AppCensus, said in a statement posted on Twitter.

How To Measure ML Model Accuracy

“A rare outcome of an experiment is more surprising than a common outcome of an experiment,” said Gerald Friedland. “If each outcome is equally likely, all outcomes have the same surprise. The quantification in bits is explained by Shannon and used in many information-coding strategies, like assigning longer strings to rarer outcomes for compression.”
