Maintaining bitcoin and other cryptocurrencies causes about 0.3 percent of global CO₂ emissions. That may not sound like a lot, but it’s more than the emissions of Switzerland, Croatia, and Norway combined. As many cryptocurrencies crash and the FTX bankruptcy moves into the litigation stage, regulators are likely to scrutinize the cryptocurrency world more than ever before. This presents a perfect opportunity to curb their environmental damage.

The good news is that cryptocurrencies don’t have to be carbon intensive. In fact, some have near-zero emissions. To encourage polluting currencies to reduce their carbon footprint, we need to force buyers to pay for their environmental harms through taxes…

The most recent iPhone update—to version 16.1.2—patches a zero-day vulnerability that “may have been actively exploited against versions of iOS released before iOS 15.1.”

News:

Apple said security researchers at Google’s Threat Analysis Group, which investigates nation state-backed spyware, hacking and cyberattacks, discovered and reported the WebKit bug.

WebKit bugs are often exploited when a person visits a malicious domain in their browser (or via the in-app browser). It’s not uncommon for bad actors to find vulnerabilities that target WebKit as a way to break into the device’s operating system and the user’s private data. WebKit bugs can be “chained” to other vulnerabilities to break through multiple layers of a device’s defenses…

Diplomatic code cracked after 500 years:

In painstaking work backed by computers, Pierrot found “distinct families” of about 120 symbols used by Charles V. “Whole words are encrypted with a single symbol” and the emperor replaced vowels coming after consonants with marks, she said, an inspiration probably coming from Arabic.

In another obstacle, he used meaningless symbols to mislead any adversary trying to decipher the message.

The breakthrough came in June when Pierrot managed to make out a phrase in the letter, and the team then cracked the code with the help of Camille Desenclos, a historian. “It was painstaking and long work but there was really a breakthrough that happened in one day, where all of a sudden we had the right hypothesis,” she said…
