Your Wi-Fi may no longer be as secure as you thought. Researchers Monday morning revealed a breach that takes advantage of Wi-Fi vulnerabilities to allow hackers to see traffic between computers and wireless hubs, notably in the popular WPA2 security scheme, ArsTechnica reports. The hacker must be close to the Wi-Fi network to execute the hack, per IBTimes.

Why it matters: The WEP scheme has previously been hacked, and this is another reminder that Wi-Fi isn't always going to be secure. As Lee Munson, Security Researcher at Comparitech.com emails, "The WPA2 encryption algorithm, which was thought to be rock solid, is so widespread in its use that its cracking potentially puts everyone at risk."

  • Precautions to take: "Users are advised to look out for the padlock symbol in their browser, or the addition of the letter 's' on the end of the http part of a web address, before sharing personal or financial information," Munson said. ArsTechnica's Dan Goodin writes, "people should avoid using Wi-Fi whenever possible until a patch or mitigation is in place…As a fall-back users should consider using a virtual private network as an added safety measure."
  • How it's happening: There's a four-way handshake that establishes a key for securing traffic, but the third step allows the key to be resent multiple times, which allows encryption to be undermined, according to a researcher briefed on the vulnerability. The researchers, the United States Computer Emergency Readiness Team and KU Leuven, report this breach, called KRACK (Key Reinstallation Attacks) could allow connection hijacking and malicious code injection.

Senate Democrats struck a deal Friday evening to extend unemployment insurance in President Biden's $1.9 trillion COVID-19 relief package after deliberating and halting other action for roughly nine hours, per a Senate aide.

Why it matters: The Senate can now resume voting on other amendments to the broader rescue bill.

A panel appointed by Congress to review security measures at the Capitol is recommending several changes, including mobile fencing and a bigger Capitol police force, to safeguard the area after a riotous mob breached the building on Jan. 6.

Why it matters: Law enforcement officials have warned there could be new plots to attack the area and target lawmakers, including during a speech President Biden is expected to give to a joint session of Congress.

Financial fallout from the Texas deep freeze

Texas has thawed out after an Arctic freeze last month threw the state into a power crisis. But the financial turmoil from power grid shock is just starting to take shape.

Why it matters: In total, electricity companies are billions of dollars short on the post-storm payments they now owe to the state's grid operator. There's no clear path for how they will pay — something being watched closely across the country as extreme weather events become more common.
