Slovak and Czech researchers have found a vulnerability that leaves government and corporate encryption cards vulnerable to hackers to impersonate key owners, inject malicious code into digitally signed software, and decrypt sensitive data, Dan Goodin reports for ArsTechnica. The researchers exposed that some of these keys can be easily hacked, which is notable since it was previously thought that these kinds of keys were virtually impervious to hackers.

Why it matters, from Axios' Senior Developer Chris Barna: Although breaking these keys could take a lot of time and money, "when you have the resources of a malicious government, 17 days and hundreds of thousands of dollars can be worth it if the perceived payoff is big enough."

What to watch for, as Graham Steel, CEO of encryption consultancy Cryptosense, told ArsTechnica: "If you have a document digitally signed with someone's private key, you can't prove it was really them who signed it. Or if you sent sensitive data encrypted under someone's public key, you can't be sure that only they can read it."

People who have been fully vaccinated against COVID-19 can take fewer precautions in certain situations, including socializing indoors without masks when in the company of low-risk or other vaccinated individuals, according to guidance from the Centers for Disease Control and Prevention released Monday.

Why it matters: The report cites early evidence that suggests vaccinated people are less likely to have asymptomatic infection, and are potentially less likely to transmit the virus to other people. At the time of its publication, the CDC said the guidance would apply to about 10% of Americans.

Ripple CEO Brad Garlinghouse tells "Axios on HBO" that if his company loses a lawsuit brought by the SEC, it would put the U.S. cryptocurrency industry at a competitive disadvantage.

Why it matters: Garlinghouse's comments may seem self-serving, but his call for clearer crypto rules is consistent with longstanding entreaties from other industry players.

Sen. Roy Blunt (R-Mo.), widely seen as a member of the Republican establishment in Congress, will not run for re-election in 2022, he announced on Twitter Monday.

Why it matters: The 71-year-old senator is the No. 4-ranking Republican in the Senate, and the fifth GOP senator to announce he will not run for re-election in 2022 as the party faces questions about its post-Trump future.
