Several new vulnerabilities with critical severity scores are causing alarm among experts and cyber officials.
Zero-day bugs affecting products from Citrix and Apache have recently been added to the Cybersecurity and Infrastructure Security Agency’s (CISA) known exploited vulnerability (KEV) list.
Incident responders at the cybersecurity company Rapid7 warned of hackers connected to the HelloKitty ransomware exploiting a vulnerability affecting Apache ActiveMQ, classified as CVE-2023-46604. Apache ActiveMQ is a Java-language open source message broker that facilitates communication between servers.
The number of ransomware attacks posted on extortion websites shot up to a record high in July, with ransomware gangs publicly claiming more than 15 attacks per day on average.
In total there were 484 ransomware attacks in July, compared to 408 the previous month, according to data collected by Recorded Future from extortion sites, government agencies, news reports, hacking forums, and other sources.
Top U.S. cybersecurity officials confirmed Thursday that several federal agencies have been impacted by cyberattacks on the widely used MOVEit file transfer tool.
Cybersecurity and Infrastructure Security Agency (CISA) Director Jen Easterly told reporters that her team and the FBI are working to provide assistance to federal agencies that used MOVEit, which is being exploited by the Russia-based Clop ransomware gang in a widespread breach that appears to have compromised dozens of entities.
“We’ve been working closely with Progress Software [which makes MOVEit], the FBI and our federal partners to understand its prevalence within federal agencies,” she said. Earlier in the day, CNN first reported that several government agencies were compromised in the hacks. Easterly said that CISA is providing support to “several agencies that have experienced intrusions of their MOVEit applications.”
