While the idea of lateral movement between IT and OT systems in the enterprise could be disastrous, the current work-from-home environment means that attacks against residential IoT systems could have a significant impact on productivity—or even become entry points for attacks against enterprise assets.
Malicious SharePoint and OneDrive Links Are a Phishing Scammer’s Dream
Attackers are exploiting the rapid adoption of cloud-based collaboration services such as Microsoft’s SharePoint Online and OneDrive by leveraging them as a social engineering tool to trick users into clicking on malicious links, often for the purpose of wire fraud or supply chain fraud. Oliver Tavakoli, CTO at Vectra, agreed that these kind of phishing scams tend to be more successful since the email is sourced by an internal party, rather than being from an external party pretending to be internal, and the links to SharePoint or OneDrive files reinforce to the victim that this is an internal communication.
NSA Lists 25 Vulnerabilities Currently Targeted by Chinese State-Sponsored Hackers
The U.S. National Security Agency this week released an advisory containing information on 25 vulnerabilities that are being actively exploited or targeted by Chinese state-sponsored threat actors.
