At least one of the security flaws is a zeroday, […]
Enlarge (credit: Getty Images) A newly discovered cryptomining worm is stepping up its targeting of Windows and Linux devices with a batch of new exploits and capabilities, a researcher said. Research company Juniper started monitoring what it’s calling the Sysrv botnet in December. One of the botnet’s malware components was a worm that spread from […]

The vulnerability this time is in BIG-IP, a line of server appliances sold by Seattle-based F5 Networks. Customers use BIG-IP servers to manage traffic […]
Enlarge (credit: Getty Images) A team of advanced hackers exploited no fewer than 11 zeroday vulnerabilities in a nine-month campaign that used compromised websites to infect fully patched devices running Windows, iOS, and Android, a Google researcher said. Using novel exploitation and obfuscation techniques, a mastery of a wide range of vulnerability types, and a […]
Enlarge (credit: Getty Images) The Microsoft Exchange vulnerabilities that allow hackers to take over Microsoft Exchange servers are under attack by no fewer than 10 advanced hacking groups, six of which began exploiting them before Microsoft released a patch, researchers reported Wednesday. That raises a vexing mystery: how did so many separate threat actors have […]
