Security Awareness – Infrastructure Entities Targeted by HTML Phishing Campaign

Security researchers have uncovered a phishing campaign targeting energy and other infrastructure companies by exploiting HTML attachments that contain credential stealing forms. In this specific campaign, the threat actor portrays the phishing email as a being from an internal source by leveraging the “Shared-Files via” feature of Microsoft 365 and masquerades as a transcript being sent to the victim. However, the email address, with a Japanese domain, is clearly visible. After downloading the HTML file, users are prompted to enter their Microsoft email password to access a fake invoice.

Ransomware Resilience – Defending against the Ransomware-as-a-Service Model

The Microsoft Threat Intelligence Center (MSTIC) just published a lengthy report providing an overview of the Ransomware-as-a-service (RaaS) threat and detailing what organizations can do to better defend against this activity. Microsoft has termed the RaaS gig economy as human-operated ransomware, where human threat actors make decisions at every stage of the attack. Despite the rising threat, there are many preventative steps organization can implement to harden their defenses. First, it’s important that companies practice credential hygiene.

Threat Awareness – Threat Actors Exploiting Event Logs to Hide Fileless Malware

Security researchers have uncovered a malicious cyber campaign that employs a novel anti-detection technique to deliver a trojan onto a targeted device. The campaign, first observed by Kaspersky, writes shellcode into Windows event logs that allows for a “fileless” last stage trojan to be hidden in a computer’s random-access memory. Injecting malware directly into system memory is what classifies as “fileless” and this technique allows threat actors to hide malicious payloads from traditional security and detection tools.
