@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: Adobe alerts customers of incoming patches for Acrobat, Reader

Description: Adobe planned to release security updates for Acrobat and Reader on Jan. 3, according to an advisory on Dec. 27. All of the vulnerabilities are considered important.

Reference: https://helpx.adobe.com/security/products/acrobat/apsb19-02.html

Snort SIDs: 48709 - 48712, 48703 - 48706


Title: Attackers leverage Brexit talks to deliver malware

Description: Security researchers believe attackers could leverage negotiations between the U.K. and European Union to deliver phishing emails. In one recent campaign, attackers pretended to be the Polish government to deliver the Zekapab malware via malicious emails. As the deadline for the two sides to reach an agreement approaches, these kinds of attacks could spike.
