Throughout the duration of COVID-19, there have been consistent rumors of increased nation-state espionage. In parallel, many recent ransomware strains have a COVID-19 tie-in. Now the United Kingdom's National Cyber Security Centre (NCSC), published an advisory report that the threat group APT29 is targeting governmental, diplomatic, think-tank, healthcare and energy targets for intelligence gain which are involved in COVID-19 vaccines development and testing.

Link-Local Multicast Name Resolution (LLMNR) and NetBIOS Name Service (NBT-NS) are two protocols that are used to identify a host address on a network when the DNS name resolution, which is the conventional method, fails to do so. When a DNS server is unable to resolve a request from a requester machine, the latter broadcasts a message to its peer computers asking for the location of the required server. Hackers leverage this operation to steal the credentials of the requester machine.

A new vulnerability, CVE-2020-8557, has been detected in kubelet. It can be exploited by writing into /etc/hosts to cause a denial of service. The source of the issue is that the /etc/hosts file mounted in a pod by kubelet is not included by the kubelet eviction manager, so it’s not taken into account when calculating ephemeral storage usage by a pod.

My colleague Greg Zweig recently wrote a blog “Forget Videobombing – Worry About What You Can’t See” in which he outlined how Unified Communications (UC) assets are all too often left unsecured, making them an easy target.

Permissions and restrictions are something used to control how much access is provided to a particular user or user group. Therefore one must first understand what is the role of a user or a group. Here, you will understand permissions and restrictions through configuring users, user groups and roles. They can either be created using configuration files or web interface. When the Icinga Web 2 is installed a default user with admin access is configured.

Within the cyber security industry, it is well known that as a company grows, so does its attack surface. This trend lends itself largely to the fact that as more employees are hired, more company-owned machines (laptops, tablets, etc.) are distributed. The risk is that once a company-owned machine is given to an employee, it is up to the employee whether to follow the security best practices set forth by your company. Your technological asset has now become a security risk.

Financial firms need to take a holistic view on their financial crime defenses to keep pace with the changing crime landscape. Dealing with the onslaught of attacks has historically elicited a Pavlovian response to this age-old problem — increased regulations or tighter risk management protocols, which in turn have proven to be ineffective over the long term.

Calico was designed from the ground up with a pluggable dataplane architecture. The Calico 3.13 release introduced an exciting new eBPF (extended Berkeley Packet Filter) dataplane targeted at those ready to adopt newer kernel versions and wanting to push the Linux kernel’s latest networking capabilities to the limit.

Customers regularly ask me what types of data sources they should be sending to their SIEMs to get the most value out of the solution. The driver for these conversations is often because the customers have been locked into a SIEM product where they have to pay more for consumption. More log data equals more money and, as a result, enterprises have to make a difficult choice around what log sources and data are what they guess is the most important.
