    Remote Code Execution in Tutanota Desktop due to Code Flaw

    In June 2022, the Sonar Research team discovered critical code vulnerabilities in multiple encrypted email solutions, including Proton Mail, Skiff, and Tutanota. These privacy-oriented webmail services provide end-to-end encryption, making communications safe in transit and at rest. Our findings affect their web clients, where the messages are decrypted with the user’s keys; mobile clients were unaffected.

    The vulnerabilities would have allowed attackers to steal emails and impersonate victims if they interacted with malicious messages. The issue has been fixed, and there are no signs of in-the-wild exploitation.

    Cisco to Acquire Splunk for $28 Billion

    Cisco will boost its cybersecurity capabilities by shelling out $28 billion to buy Splunk, which Cisco says will drive the next generation of AI-enabled security and observability.

    Cisco on Thursday announced that it has entered into a definitive agreement to acquire data analysis, security and observability solutions provider Splunk (NASDAQ: SPLK) in a deal valued at $28 billion.

    The networking giant is prepared to pay $157 per share in cash for Splunk, with the acquisition expected to close by the end of the third quarter calendar year 2024. Cisco said the deal will help accelerate revenue growth and gross margin expansion.

    Following the acquisition, Splunk President and CEO Gary Steele will join Cisco’s executive team and will report to Cisco CEO and Chair Chuck Robbins.

    Splunk’s AI, security and observability capabilities complement Cisco’s offering.

    “Uniting with Cisco represents the next phase of Splunk’s growth journey, accelerating our mission to help organizations worldwide become more resilient, while delivering immediate and compelling value to our shareholders,” Steele said.
