All of the nations are NATO members, but the deals have been negotiated bilaterally.  The security deals are “very important to Ukraine” because they guarantee long-term aid — including in cyberspace — while it waits to join NATO, said Oleksandr Potii, the deputy head of the country’s service of special communications and information protection (SSSCIP).

Largest ever operation against botnets hits dropper malware ecosystem 

Between 27 and 29 May 2024 Operation Endgame, coordinated from Europol’s headquarters, targeted droppers including, IcedID, SystemBC, Pikabot, Smokeloader, Bumblebee and Trickbot. The actions focused on disrupting criminal services through arresting High Value Targets, taking down the criminal infrastructures and freezing illegal proceeds. This approach had a global impact on the dropper ecosystem. The malware, whose infrastructure was taken down during the action days, facilitated attacks with ransomware and other malicious software.

The individuals are wanted for their involvement in serious cybercrime activities. 


CISA Alerts Federal Agencies to Patch Actively Exploited Linux Kernel Flaw 

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a security flaw impacting the Linux kernel to the Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. Tracked as CVE-2024-1086 (CVSS score: 7.8), the high-severity issue relates to a use-after-free bug in the netfilter component that permits a local attacker to elevate privileges from a regular user to root and possibly execute arbitrary code. “Linux kernel contains a use-after-free vulnerability in the netfilter: nf_tables component that allows an attacker to achieve local privilege escalation,” CISA said.
