@Risk: Security Alert
OUCH! Security Awareness
Case Leads DFIR Digest
Industrial Control Systems
Industrials & Infrastructure


@RISK provides a reliable weekly summary of (1) newly discovered attack vectors, (2) vulnerabilities with active new exploits, (3) insightful explanations of how recent attacks worked, and other valuable data

A key purpose of the @RISK is to provide the data that will ensure that the 20 Critical Controls (the US and UK benchmark for effective protection of networked systems) continue to be the most effective defenses for all known attack vectors. But since it is also valuable for security practitioners, SANS is making it available to the 145,000 security practitioners who have completed SANS security training and others at their organizations who hope to stay current with the offensive methods in use.

NOTABLE RECENT SECURITY ISSUES

SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP


Title: Aggah spam campaign upgrades, finds new ways to avoid detection

Description: A new Aggah campaign pushes malicious Microsoft Office documents (maldocs) via malicious spam (malspam) emails distributing a multi-stage infection to a target user's endpoint. The final payload of the infection consists of a variety of Remote-Access-Tool (RAT) families such as Agent Tesla, njRAT and Nanocore RAT. Consistent with previous Aggah campaigns, this campaign also focuses on the use of pastebin[.]com for all its infrastructure needs. However, this campaign now utilizes multiple Pastebin accounts to host different stages of the attack.

Reference: https://blog.talosintelligence.com/2020/04/upgraded-aggah-malspam-campaign.html

Snort SIDs: 53745 - 53748


Title: Microsoft warns of Remcos campaign using COVID-19-themed lures

Description: A series of Remcos campaigns launched across the globe are using COVID-19-themed lure files to infect users. Microsoft says attackers are using specially crafted disk image files that contain malware, targeting major government agencies such as the U.S. Small Business Administration and manufacturing companies in South Korea. The phishing emails use subject lines related to the COVID-19 pandemic to trick users into opening the emails.
