The complex dance of two black holes locked in a doomed orbit has been revealed in a first-of-its-kind direct radio image.
It’s the first time astronomers have directly imaged the distinct jets of both black holes in a known binary – finally confirming the model of the double core of a galaxy called OJ 287.
In OJ 287, located some 3.5 billion light-years away, the intricate, extreme interplay between the two central supermassive black holes has been documented for decades. This is the first image to capture smoking-gun signatures of both objects, however.
Cybersecurity researchers are calling attention to a new campaign that delivers the Astaroth banking trojan that employs GitHub as a backbone for its operations to stay resilient in the face of infrastructure takedowns.
“Instead of relying solely on traditional command-and-control (C2) servers that can be taken down, these attackers are leveraging GitHub repositories to host malware configurations,” McAfee Labs researchers Harshil Patel and Prabudh Chakravorty said in a report.
“When law enforcement or security researchers shut down their C2 infrastructure, Astaroth simply pulls fresh configurations from GitHub and keeps running.”
A large-scale botnet is targeting Remote Desktop Protocol (RDP) services in the United States from more than 100,000 IP addresses.
The campaign started on October 8 and based on the source of the IPs, researchers believe the attacks are launched by a multi-country botnet.
RDP is a network protocol that enables remote connection and control of Windows systems. It is typically used by administrators, helpdesk staff, and remote workers.
