Chinese hackers who penetrated U.S. telecoms likely haven't been fully evicted partially due to shifting tactics made in response to public disclosures, federal officials said Tuesday. Industry and government investigators have revealed in dribs and drabs a campaign of Beijing telecom hacking.
A Russian cyberespionage group hacked a Washington, D.C.-based organization focused on Ukraine by deploying a new attack technique that exploits Wi-Fi connectivity, according to new research. The "nearest neighbor attack methodology could lead to a significant broadening of targeting and attacks.
Attackers wielding an emerging strain of ransomware called Helldown have been gaining a foothold in victims' networks by exploiting a previously unknown flaw in their Zyxel firewalls, security researchers warn. Zyxel has warned attackers may be using valid credentials they previously stole.
Attackers are exploiting a zero-day vulnerability in some types of Palo Alto Networks firewalls, the cybersecurity giant warned. While details of the flaw remain scant - no patch is available - the vendor urged customers to ensure their firewall management interfaces are not internet-exposed.
Firewall maker Sophos disclosed Thursday a half-decade worth of efforts by multiple nation-state Chinese hacking groups to infiltrate its appliances, calling the admission a wake-up call for the cybersecurity industry. Targeting firewall appliances is a known nation-state tactic.
Researchers at Mandiant say a new threat cluster, first observed June 27, has been exploiting a Fortinet zero-day that the network edge device manufacturer publicly disclosed Wednesday. Researchers said they can't assess the threat actor's motivation or location.
Fortinet disclosed an actively exploited vulnerability in its centralized management platform following more than a week of online chatter that edge device manufacturer products have been under renewed attack. Cybersecurity researcher Kevin Beaumont christened the vulnerability "FortiJump."
Unencrypted cookies tied to a suite of secure gateway technology from F5 are gateways for hackers to reach internal devices on corporate networks, warns the Cybersecurity and Infrastructure Security Agency. BIG-IP uses persistent cookies as a traffic load-balancing convenience.
Internet appliance maker Ivanti warned customers Tuesday that attackers are actively exploiting new vulnerabilities in Cloud Services Appliance instances by chaining three security flaws with a zero-day patched in September. The company advised customers to update to version 5.0.
Illumio and Akamai remained atop Forrester's microsegmentation rankings, while ColorTokens and Cisco climbed into the leader space.The microsegmentation market has expanded beyond traditional on-premises networks to address modern public cloud workloads.
Ivanti confirmed that hackers are exploiting an SQL injection vulnerability in its Ivanti Endpoint Manager enabling remote code execution, despite the company addressing the issue with a patch in May. The flaw allows unauthenticated attackers within the same network to execute arbitrary code.
Neglecting network security can lead to serious consequences for organizations. Here are the essential practices for managing network security, along with real-world examples that reinforce the importance of comprehensive protection. The time to secure your network is now - before it's too late.
A Chinese state-sponsored botnet called Raptor Train has infected more than 260,000 IoT and office network devices to target critical infrastructure globally. The hackers used zero-days and known vulnerabilities to compromise more than 20 different types of devices to expand their botnet.
ColorTokens purchased PureID, expanding its zero trust framework with identity-based segmentation for cloud and hybrid environments. The acquisition focuses on securing cloud applications, microservices and APIs through advanced identity-based authentication.
Operators behind a mysterious botnet named for a TCP routing port number are expanding the universe of targeted devices and taking steps to hide their infrastructure, warn Sekoia researchers. The 7777 - or Quad7 - botnet appears to have emerged in 2023.
