Subtle fluctuations in internet activity can serve as premonitory indicators of severe vulnerabilities long before their public disclosure. A nascent report by GreyNoise reveals that adversaries frequently initiate aggressive scanning and reconnaissance of infrastructure...
A diminutive cluster of servers has managed, in a matter of mere hours, to redraw the conventional cartography of internet reconnaissance. According to data from GreyNoise, a scant twenty-one IP addresses orchestrated nearly half...
Adversaries have embarked upon a pervasive reconnaissance of the internet, systematically identifying misconfigured proxy servers that facilitate unauthorized access to commercial services predicated on Large Language Models (LLMs). This campaign, manifesting as a methodical...
In the midst of the Christmas holidays, researchers at Greynoise detected a large-scale cyberattack targeting vulnerable Adobe ColdFusion servers. Within a short period, more than 2.5 million malicious requests were recorded, pointing to a...
GreyNoise Labs has unveiled GreyNoise IP Check, an online service that allows users to determine whether their IP address has been observed participating in suspicious scanning activity linked to botnets or residential proxy networks....
GreyNoise has recorded a dramatic surge in automated requests targeting Palo Alto Networks’ GlobalProtect authentication portals. The scale of this spike is highly atypical: within just 24 hours, the volume of network sessions hitting...
Since the beginning of October, GreyNoise analysts have been tracking one of the largest and most coordinated waves of attacks targeting remote access services across the United States. According to their findings, since October...
At the end of August, GreyNoise recorded a sharp surge in scanner activity targeting Cisco ASA devices. Experts warn that such waves often precede the discovery of new vulnerabilities in these products. This time,...
GreyNoise has observed a sharp and highly atypical surge in reconnaissance activity targeting Microsoft Remote Desktop Web Access and the RDP Web Client: 1,971 unique IP addresses were active simultaneously, whereas the company typically...
The GreyNoise team has uncovered a disquieting pattern: in 80% of cases, anomalous spikes in suspicious internet activity occur prior to the official disclosure of new vulnerabilities (CVEs). These are not coincidences or random...
