@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: Snake/Ekans malware adds new functionality to go after ICS
Description: The Snake ransomware (otherwise known as "Ekans") has added new capabilities aimed at going after industrial industries. Ekans first emerged in December, but now has a relationship with the MEGACORTEX ransomware that could allow it to spread quickly on ICS systems and even force some services to revert to manual operations. The malware's code now includes direct references to HMI processes and historian clients that are commonly linked to ICS.

Snort SIDs: 53106, 53107
Title: Carrotbat malware, Syscon backdoor team up to target federal government
Description: An American federal agency was targeted in late January with a series of phishing emails utilizing a variant of the Carrotbat malware and the Syscon backdoor. Attackers used six unique email attachments in the campaign, all relating to the ongoing strained relationship between the U.S. and North Korea. Security researchers say these attackers are still active, despite the majority of their activity taking places over the summer.

RECENT VULNERABILITIES FOR WHICH EXPLOITS ARE AVAILABLE
COMPILED BY THE QUALYS VULNERABILITY RESEARCH TEAM
This is a list of recent vulnerabilities for which exploits are
available. System administrators can use this list to help in
prioritization of their remediation activities. The Qualys Vulnerability
Research Team compiles this information based on various exploit
frameworks, exploit databases, exploit kits and monitoring of internet
activity.
ID: CVE-2020-0618
Title: Microsoft SQL Server Reporting Services Remote Code Execution Vulnerability
Vendor: Microsoft
Description: A remote code execution vulnerability exists in Microsoft SQL Server Reporting Services when it incorrectly handles page requests. An attacker who successfully exploited this vulnerability could execute code in the context of the Report Server service account. To exploit the vulnerability, an authenticated attacker would need to submit a specially crafted page request to an affected Reporting Services instance.
CVSS v2 Base Score: 6.5 (AV:N/AC:L/Au:S/C:P/I:P/A:P)
ID: CVE-2020-0668
Title: Microsoft Windows Kernel Elevation of Privilege Vulnerability
Vendor: Microsoft
Description: An elevation of privilege vulnerability exists in the way that the Windows Kernel handles objects in memory, aka 'Windows Kernel Elevation of Privilege Vulnerability'
CVSS v2 Base Score: 4.6 (AV:L/AC:L/Au:N/C:P/I:P/A:P)
ID: CVE-2019-18683
Title: Linux kernel vulnerability in the V4L2 subsystem
Vendor: Multi-Vendor
Description: These vulnerabilities are caused by incorrect mutex locking in the vivid driver of the V4L2 subsystem (drivers/media/platform/vivid). This driver doesn't require any special hardware. It is shipped in Ubuntu, Debian, Arch Linux, SUSE Linux Enterprise, and openSUSE as a kernel module (CONFIG_VIDEO_VIVID=m).
CVSS v2 Base Score: 6.9 (AV:L/AC:M/Au:N/C:C/I:C/A:C)
ID: CVE-2020-0601
Title: Microsoft Windows CryptoAPI Spoofing Vulnerability
Vendor: Microsoft
Description: A spoofing vulnerability exists in the way Windows CryptoAPI (Crypt32.dll) validates Elliptic Curve Cryptography (ECC) certificates. An attacker could exploit the vulnerability by using a spoofed code-signing certificate to sign a malicious executable, making it appear the file was from a trusted, legitimate source. The user would have no way of knowing the file was malicious, because the digital signature would appear to be from a trusted provider.
A successful exploit could also allow the attacker to conduct man-in-the-middle attacks and decrypt confidential information on user connections to the affected software.
CVSS v2 Base Score:5.8 (AV:N/AC:M/Au:N/C:N/I:P/A:N)
ID: CVE-2019-19781
Title: Citrix ADC And Citrix Gateway Arbitrary Code Execution Vulnerability
Vendor: Citrix
Description: A vulnerability has been identified in Citrix Application Delivery Controller (ADC) formerly known as NetScaler ADC and Citrix Gateway formerly known as NetScaler Gateway that, if exploited, could allow an unauthenticated attacker to perform arbitrary code execution. Successfully exploiting this issue will allow attackers to execute arbitrary code within the context of the application.
CVSS v2 Base Score: 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)
ID: CVE-2020-0683
Title: Microsoft Windows Installer Elevation of Privilege Vulnerability
Vendor: Microsoft
Description: An elevation of privilege vulnerability exists in the Windows Installer when MSI packages process symbolic links. An elevation of privilege vulnerability exists in the Windows Installer when MSI packages process symbolic links. An attacker who successfully exploited this vulnerability could bypass access restrictions to add or remove files.
CVSS v2 Base Score: 7.2 (AV:L/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2020-7247
Title: OpenBSD OpenSMTPD Arbitrary Commands Execution Vulnerability
Vendor: OpenBSD
Description: smtp_mailaddr in smtp_session.c in OpenSMTPD 6.6, as used in OpenBSD 6.6 and other products, allows remote attackers to execute arbitrary commands as root via a crafted SMTP session, as demonstrated by shell metacharacters in a MAIL FROM field. This affects the "uncommented" default configuration. The issue exists because of an incorrect return value upon failure of input validation.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2019-11510
Title: Pulse Secure Arbitrary File Disclosure Vulnerability
Vendor: Pulse Secure
Description: Pulse Connect Secure is exposed to arbitrary file disclosure vulnerability. An attacker can exploit these issues to access arbitrary files in the context of the application, write arbitrary files, or can send a specially crafted URI to perform an arbitrary file reading vulnerability.
CVSS v2 Base Score: 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)
