Akira ransomware exploiting critical SonicWall SSLVPN bug again

The Akira ransomware gang is actively exploiting CVE-2024-40766, a year-old critical-severity access control vulnerability, to gain unauthorized access to SonicWall devices.

5 Best Electric Toothbrushes, Backed by Dentists and Hygienists

What About U-Shaped Toothbrushes? There are many U-shaped toothbrushes available now that use a mouthpiece full of bristles to brush one section of teeth—or sometimes the entire mouth—all at once in around 30 seconds. We've tried a few and think they're fine to use in addition to regular brushing. None of them are as effective as standard electric toothbrushes. Bill Busch of North Kansas City Dental and Joseph Salim, owner of Sutton Place Dental Associates, agree that these aren't replacements.

SonicWall finds no SSLVPN zero-day, links ransomware attacks to 2024 flaw

SonicWall says that recent Akira ransomware attacks exploiting Gen 7 firewalls with SSLVPN enabled are exploiting an older vulnerability rather than a zero-day flaw. The company says that the attackers are targeting CVE-2024-40766, an unauthorized access flaw fixed in August 2024. "We now have high confidence that the recent SSLVPN activity is not connected to a zero-day vulnerability," reads the update on the SonicWall bulletin published this week. "Instead, there is a significant correlatio

SonicWall urges admins to disable SSLVPN amid rising attacks
