The latest edition of the ISMG Security Report features an analysis of the Log4j security flaw, including the risks and mitigation techniques, how to patch Log4j, and CISO Dawn Cappelli on Log4j response.
The U.S. Department of Homeland Security this week announced a "Hack DHS" bug bounty program to identify potential cybersecurity vulnerabilities within its systems and to increase DHS' overall cyber resilience. Hackers uncovering vulnerabilities will be compensated by the department.
Attackers tied to China, Iran, North Korea and Turkey have been targeting or testing exploits of the ubiquitous Apache Log4j vulnerability. Vendors are rushing to identify and patch supported software and hardware as cybersecurity agencies urge organizations to mitigate the threat and beware exploit attempts.
It’s no secret that the recent large-scale ransomware attacks are a call to action for greater federal cybersecurity regulations. As it stands, security policies are not mandated and are largely a voluntary mechanism. But it has become apparent that at-will standards are not getting the job done. According to a...
December’s Microsoft Patch Tuesday covers 67 security fixes, one of which is a zero-day vulnerability spreading Emotet malware. Five of the other bugs are listed as publicly known, but not yet exploited. Additionally, Google, Apple and Adobe also released critical updates.
Security and IT teams racing to mitigate the threat posed by the ubiquitous Apache Log4j 2.14 flaw are facing a new problem: Which version of the patched software should they deploy - 2.15.0 or the newly released 2.16.0?
What's in store for defenders as attackers increasingly try to target the ubiquitous Apache Log4j vulnerability? "Everyone is a target," says veteran cybersecurity leader Etay Maor, whose team at Cato Networks has been analyzing hundreds of attacks that already attempt to exploit the flaw.
Like CISOs everywhere, Dawn Cappelli of Rockwell Automation awoke last Friday to news about the Log4j vulnerability and the risk it posed to her company, customers and partners. Here is how she approached triage, response and capturing insights to be shared with other security leaders.
The year is ending with a cybersecurity bang - not whimper - due to the widespread prevalence of the Apache Log4j vulnerability. Researchers warn that at least 40% of corporate networks have been targeted by attackers seeking to exploit the flaw. More than 250 vendors have already issued security advisories.
Multiple security researchers have spotted threat actors already exploiting the Apache Log4j vulnerability by deploying Muhstik and Mirai botnets to target Linux devices. Their advice: Ensure to remove any existing compromise before patching, and expect this flaw to be exploited for the long term.
A massive wave of ongoing attacks has been targeting more than 1.6 million WordPress sites, researchers at Wordfence say. So far, they've counted more than 13.7 million individual attacks in just 36 hours, focused on exploiting four different WordPress plug-ins and several Epsilon framework themes.
Researchers have developed and released an urgent "vaccine" for a zero-day vulnerability detected in the Java logging library Apache Log4j on Friday. It is reported that the vulnerability is being exploited by advanced persistent threat-level actors.
How serious is the Apache Log4j zero-day vulnerability that was announced to the world on Friday? "It's big," says Sam Curry, chief security officer at Cybereason, which has developed a "vaccine" to help. "I hate hyperbole generally," Curry says. "But it is a 10 on the criticality scale."
