@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: Microsoft patches 49 vulnerabilities as part of Patch Tuesday
Description: Microsoft released its monthly security update today, disclosing vulnerabilities across many of its products and releasing corresponding updates. Patch Tuesday covers 49 vulnerabilities, eight of which are considered critical. This month's security update is particularly important for its disclosure of two vulnerabilities related to a core cryptographic component in all versions of Windows. CVE-2020-0601 could allow an attacker to use cryptography to sign a malicious executable, making the file appear as if it was from a trusted source. The victim would have no way of knowing if the file was malicious. Cyber security reporter Brian Krebs says the vulnerability is so serious, Microsoft secretly deployed a patch to branches of the U.S. military prior to today.

Snort SIDs: 52593 - 51596, 52604, 52605
Title: ZeroCleare wiper malware deployed on oil refinery
Description: ZeroCleare, a wiper malware connected to an Iranian hacker group, was recently deployed against a national oil refinery in Bahrain. An upgraded version has been spotted in the wild, according to security researchers, which can delete files off infected machines. The latest attacks match previous attacks using this malware family, which have gone after other targets connected to Saudi Arabia. Concerns over Iranian cyber attacks have spiked since the U.S. killed a high-profile Iranian general in a drone strike.

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-2020-0601
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-2020-0632
Title: Microsoft Windows Search Indexer Elevation of Privilege Vulnerability
Vendor: Microsoft
Description: An elevation of privilege vulnerability exists in the way that the Windows Search Indexer handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions. To exploit the vulnerability, a locally authenticated attacker could run a specially crafted application.
CVSS v2 Base Score: 4.6 (AV:L/AC:L/Au:N/C:P/I:P/A:P)
ID: CVE-2020-3941
Title: VMWare Privilege Escalation Vulnerability
Vendor: VMWare
Description: A vulnerability exists in VMware Tools for windows, which may allow for privilege escalation in the Virtual Machine where Tools is installed. A malicious actor on the guest VM might exploit the race condition and escalate their privileges on a Windows VM.
CVSS v2 Base Score: 7.2 (AV:L/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2019-18244
Title: OSIsoft Sensitive Information Disclosure Vulnerability
Vendor: OSIsoft LLC
Description: The vulnerability exists due to the affected software records the service account password in the installation log files when a non-default service account and password are specified during installation or upgrade. A local attacker can gain access to sensitive information on the target system.
CVSS v2 Base Score: 4.7 (AV:L/AC:M/Au:N/C:C/I:N/A:N)
ID: CVE-2019-18271
Title: OSIsoft Cross Site Request Forgery Vulnerability
Vendor: OSIsoft LLC
Description: The vulnerability exists due to insufficient validation of the HTTP request origin on the PI Vision administration site. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website. The vulnerability allows a remote attacker to perform cross-site request forgery attacks.
CVSS v2 Base Score: 7.0 (AV:N/AC:M/Au:S/C:P/I:N/A:C)
