At the end of January, the Health Sector Cybersecurity Coordination Center warned that the KillNet group is actively targeting the US healthcare sector with distributed denial-of-service (DDoS) attacks. The Cybersecurity and Infrastructure Security Agency (CISA) says it helped dozens of hospitals respond to these DDoS incidents.
While achieving compliance with industry standards is the minimum, it’s not enough to prevent insider threats, supply chain attacks, DDoS, or sophisticated cyberattacks such as double-extortion ransomware, phishing, business email compromise (BEC), info-stealing malware or attacks that leverage the domain name system (DNS).
(“TA”), today announced it has completed its acquisition of Vercara, a leader in cloud-based services that secure the online experience, including managed authoritative Domain Name System (DNS) and Distributed Denial-of-Service (DDoS) security offerings that protect organizations’ networks and applications.
Distributed denial of service (DDoS) attacks can cripple an organization, a network, or even an entire country, and they show no sign of slowing down. DDoS attacks may only make up a small percentage of security threats, but their consequences can be devastating. According to Imperva Research Labs, DDoS attacks tend to come in waves.
And even a record-breaking year in Distributed Denial of Service ( DDoS ) attacks might have been expected as it follows the upward trend over the years. But the sheer number of attacks, their size, and a new big player in the field of DDoS extortion may raise some surprised eyebrows. The records. New methods. Lazarus Bear Armada.
Vendor reports note huge volume of attacks on local and public infrastructure, such as: CrowdStrike: Monitored hacktivist and nation-state distributed denial of service (DDoS) attacks related to the Israli-Palestinian conflict, including against a US airport. 50,000 DDoS attacks on public domain name service (DNS) resolvers.
The findings in the report expose weaknesses in security controls that leave web applications vulnerable to severe cyberattacks, including Distributed Denial-of-Service (DDoS) and data breaches. Threat actors can exploit these gaps to launch DDoS attacks, steal sensitive data, and even compromise entire systems. million per incident.
Malicious bots can be used to carry out a range of cyber threats like account takeovers and DDoS attacks, so bot protection is an increasingly important defense for web-facing assets. Bot protection products can also help prevent DDoS attacks. Limited customization options for smaller businesses.
In 2015, the education sector was among the top three sectors breached , behind healthcare and retail. Some of the most common attacks cybercriminals use to breach higher education institutions are hacking, malware and DDoS attacks. Take it from Rutgers University, which experienced six DDoS attacks in 2015.
Critical applications and internal processes, such as Active Directory (AD) ; Domain Name System (DNS) ; and accounting, banking, or operations management software. This software contains vulnerability CVE-2022-24198 that allows a specially crafted PDF to cause a distributed denial-of-service (DDoS) attack. Overwhelming Workloads.
DNS attacks : DNS cache poisoning, or hijacking, redirects a legitimate site’s DNS address and takes users to a malicious site when they attempt to navigate to that webpage. DoS and DDoS attacks DDoS attacks can make your public-facing applications and websites inaccessible, causing massive revenue loss.
Other hackers might use a spoofed domain name system (DNS) or IP addresses to redirect users from legitimate connections (to websites, servers, etc.) Distributed denial of service (DDoS) attacks currently will be used more often against internet-exposed resources, but can also be used by an attacker to take down networks and internal servers.
This testing helps identify risks like unpatched software, misconfigured DNS, and vulnerable web applications, all possible entry points for external threats. It involves scanning for vulnerabilities in external-facing systems, identifying misconfigurations, unpatched software, and weaknesses in firewall rules or DNS setups.
