The Five Eyes (FVEY) intelligence alliance has issued a new cybersecurity advisory warning of cyber threat actors exploiting known security flaws in Ivanti Connect Secure and Ivanti Policy Secure...
The U.S. Cybersecurity and Infrastructure Security Agency revealed today that attackers who hack Ivanti VPN appliances using one of multiple actively exploited vulnerabilities may be able to maintain root persistence even after performing factory resets. The authoring organizations encourage network defenders to assume that user and service account credentials stored within the affected Ivanti VPN appliances are likely compromised, hunt for malicious activity on their networks using the detection methods and indicators of compromise within this advisory, run Ivanti's most recent external ICT, and apply available patching guidance provided by Ivanti as version updates become available.
In 2023, malicious email threats bypassing secure email gateways increased by more than 100%, according to Cofense. "As we unveil the statistics from the 2024 Annual State of Email Security Report, it's evident that the email-based attack vector is evolving at an unprecedented pace going into 2024," said David Van Allen, CEO of Cofense.
Thousands of Ivanti Connect Secure and Policy Secure endpoints remain vulnerable to multiple security issues first disclosed more than a month ago and which the vendor gradually patched. Starting with CVE-2024-22024, the issue is an XXE vulnerability in the SAML component of Ivanti Connect Secure, Policy Secure, and ZTA gateways that allowsunauthorized access to restricted resources.
Ivanti has alerted customers of yet another high-severity security flaw in its Connect Secure, Policy Secure, and ZTA gateway devices that could allow attackers to bypass authentication. The...
Cisco has patched several vulnerabilities affecting its Expressway Series collaboration gateways, two of them rated as critical severity and exposing vulnerable devices to cross-site request forgery attacks.Unauthenticated attackers can exploit the two critical CSRF vulnerabilities patched today to target unpatched Expressway gateways remotely.
The network is at an inflection point, and organizations' networks have become more dispersed amongst the cloud and on-prem, prompting a greater need for visibility today than ever. As the nature of the network shifts, teams face challenges securing their organization's infrastructure, and many fall short.
NET-based information stealer malware dubbed SapphireStealer is being used by multiple entities to enhance its capabilities and spawn their own bespoke variants. "Information-stealing malware like SapphireStealer can be used to obtain sensitive information, including corporate credentials, which are often resold to other threat actors who leverage the access for additional attacks, including operations related to espionage or ransomware/extortion," Cisco Talos researcher Edmund Brumaghin said in a report shared with The Hacker News.
Nearly a third of organizations compromised by Chinese cyberspies via a critical bug in some Barracuda Email Security Gateways were government units, according to Mandiant. Mandiant continues to recommend people dump and replace their at-risk Barracuda equipment.
The U.S. Federal Bureau of Investigation is warning that Barracuda Networks Email Security Gateway appliances patched against a recently disclosed critical flaw continue to be at risk of potential compromise from suspected Chinese hacking groups. It also deemed the fixes as "Ineffective" and that it "Continues to observe active intrusions and considers all affected Barracuda ESG appliances to be compromised and vulnerable to this exploit."
