The targets have included diplomatic entities, think tanks, non-governmental organizations (NGOs), religious organizations, telecommunication companies, and political activists.

Post Title

Multiple vulnerabilities have been discovered in F5Networks products, the most severe of which could result in arbitrary code execution.

BIG-IP is a family of products covering software and hardware designed around application availability, access control, and security solutions.
Traffix SDC is a product that provides load balancing and gateway connectivity.
Big-IQ Centralized Management tracks assets and manages policies for BIG-IP products.
F5 Access for Android is an Android application that allows users to access enterprise networks and applications.
BIG-IP Guided Configuration is a products that provides a way to deploy configurations of BIP-IP APM and Advanced WAF.
The F5OS-A is the operating system software for the F5 rSeries system.
NGINX Service Mesh is a product that allows for traffic control of distributed systems.
BIG-IP APM provides access control and authentication for applications.
Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

15.3 Million Request-Per-Second DDoS Attack

Read Time:39 Second

Cloudflare is reporting a large DDoS attack against an unnamed company “operating a crypto launchpad.”

While this isn’t the largest application-layer attack we’ve seen, it is the largest we’ve seen over HTTPS. HTTPS DDoS attacks are more expensive in terms of required computational resources because of the higher cost of establishing a secure TLS encrypted connection. Therefore it costs the attacker more to launch the attack, and for the victim to mitigate it. We’ve seen very large attacks in the past over (unencrypted) HTTP, but this attack stands out because of the resources it required at its scale.

The attack only lasted 15 seconds. No word on motive. Was this a test? Or was that 15-second delay critical for some other fraud?
