An updated version of an information-stealing malware called Rhadamanthys is being used in phishing campaigns targeting the oil and gas sector. "The phishing emails use a unique vehicle incident lure and, in later stages of the infection chain, spoof the Federal Bureau of Transportation in a PDF that mentions a significant fine for the incident," Cofense researcher Dylan Duncan said. The…

Operational Technology (OT) refers to the hardware and software used to change, monitor, or control the enterprise's physical devices, processes, and events. Unlike traditional Information Technology (IT) systems, OT systems directly impact the physical world. This unique characteristic of OT brings additional cybersecurity considerations not typically present in conventional IT security…

New research has found that the CONTINUATION frame in the HTTP/2 protocol can be exploited to conduct denial-of-service (DoS) attacks.

The U.S. Cyber Safety Review Board (CSRB) has criticized Microsoft for a series of security lapses that led to the breach of nearly two dozen companies across Europe and the U.S. by a China-based nation-state group called Storm-0558 last year. The findings, released by the Department of Homeland Security (DHS) on Tuesday, found that the intrusion was preventable, and that it became successful…

Google on Tuesday said it's piloting a new feature in Chrome called Device Bound Session Credentials (DBSC) to help protect users against session cookie theft by malware. The prototype – currently tested against "some" Google Account users running Chrome Beta – is built with an aim to make it an open web standard, the tech giant's Chromium team said. "By binding authentication sessions to the…

Attack surface management (ASM) and vulnerability management (VM) are often confused, and while they overlap, they’re not the same. The main difference between attack surface management and vulnerability management is in their scope: vulnerability management checks a list of known assets, while attack surface management assumes you have unknown assets and so begins with discovery. Let’s look at…
