A recent SMS text message phishing (SMiShing) campaign is targeting Verizon Wireless customers and customers of other providers that piggyback off the Verizon network, such as Spectrum . These messages are spoofed to appear as though the message was sent from the recipient’s own phone number. The messages vary but typically thank the recipient for paying their bill and offer a gift. The messages include a link to accept the gift. These links may lead to malicious websites intending to steal account credentials or personal information, or install malware. A similar campaign targeted AT&T customers in August 2021.

 Researchers discovered that
Cyclops Blink, a botnet linked to Russian advanced
persistent threat group Sandworm, is actively targeting ASUS
routers and WatchGuardfirewall appliances. The malware is modular – meaning it can easily be
updated to target new devices – and features a specialized module that may
allow the malware to read flash memory in order to gather information about
critical files, executables, data, and libraries. The malware then receives a
command to nest in the flash memory and establish persistence, as this storage
space can survive factory resets. Due to the number of indiscriminate targets,
analysts assess that the group’s intent behind this iteration of distribution
is to build and maintain a botnet infrastructure for future attacks on
high-value targets.

A few days ago, I found an
interesting and dangerous situation that I would like to warn you about.

 A company I know well was
under attack from a weakness on their web site.  It was a major intrusion
that needed immediate attention.

 My issues started when I tried
to contact anyone at the company to warn them about the problem.  

 I had to go through a “phone
tree” for support. When I finally got a human to answer, and I explained the
nature of the problem, and how it was time sensitive, the response I got was,
“Thanks for the information. Someone will get back to you in a WEEK! 
(the people who answered the phone were not IT support!)  

 What are your support staff
trained to do when an issue is called in? Do you train them and test the
process?  Think about the issues if this was ransomware!!  How long
would support have waited to call level 2 support?  How much data would
your company lose while waiting for a ticket to even get to the proper person ?

 TRAIN YOUR STAFF NOW so
that they can handle and respond to risks quickly in an appropriate
manner.  Don’t become a victim! 

 

The list provided below is meant to provide an overview of the most prevalent exploit kit variants currently impacting US victims. This page is updated regularly with new information as it becomes available.

CrowdStrike security researchers discovered a high severity vulnerability, dubbed “cr8escape,” in the Kubernetes container engine CRI-O – an open source, community-driven container engine. Each Kubernetes node includes a container runtime such as CRI-O. Among other tasks, the container runtime allows containerized apps to safely share each node’s underlying Linux kernel and other resources. The flaw, tracked as CVE-2022-0811  (CVSS v3 8.8), exists due to the addition of sysctl support in version 1.19 used to configure kernel parameters at runtime. Researchers determined that this flaw will now “blindly set any kernel parameters it is passed without validation, meaning that anyone who can deploy a pod on a cluster using the CRI-O runtime can abuse the kernel.core_pattern  parameter to achieve container escape and arbitrary code execution as root on any node in the cluster.” Malicious threat actors may be able to exploit the vulnerability in the components of the Kubernetes architecture, such as the control plane, worker nodes, or containerized applications, to exfiltrate data and move laterally across pods. The potential impact of this flaw is widespread due to the number of platforms that use CRI-O, such as OpenShift and Oracle Container Engine for Kubernetes. The vulnerability has been resolved and researchers urge users to patch immediately.

 

 QNAP is notifying users that Network Attached Storage (NAS) devices are impacted by the high severity Linux vulnerability dubbed “Dirty Pipe” that allows attackers with local access to gain root privileges. 

Dirty Pipe a vulnerability was discovered in the Linux kernels’ handling of pipe buffer flags affecting Linux kernel versions 5.8 and later as well as some Android kernel versions. CVE-2022-0847 (CVSS v3 7.8), may allow a non-privileged user to overwrite data in arbitrary read-only files and SUID binaries. Successful exploitation of this vulnerability may allow for root privilege escalation through the editing of administrative files such as /etc/passwd and SUID programs. 

Proof of Concept (PoC) exploits have been made publicly available. Although a patch was released for the flaw, QNAP states that there is no mitigation available at this time, further recommending that users install the security updates as soon as possible. Impacted NAS devices comprise of those running QTS 5.0.x and QuTS hero h5.0.x, including: QTS 5.0.x on all QNAP x86-based NAS and certain QNAP ARM-based NAS; and QuTS hero h5.0.x on all QNAP x86-based NAS and certain QNAP ARM-based NAS.

 CISA and the Federal Bureau of Investigation (FBI) have released a joint Cybersecurity
Advisory that details how Russian state-sponsored cyber actors
accessed a network with misconfigured default multifactor authentication (MFA)
protocols. The actors then exploited a critical Windows Print Spooler
vulnerability, “PrintNightmare” (CVE-2021-34527), to run arbitrary code with
system privileges. The advisory provides observed tactics, techniques, and
procedures, as well as indicators of compromise and mitigations to protect
against this threat. 

CISA encourages users and administrators to review AA22-074A: Russian
State-Sponsored Cyber Actors Gain Network Access by Exploiting Default
Multifactor Authentication Protocols and “PrintNightmare” Vulnerability.

information on the threat of Russian state-sponsored malicious cyber actors to
U.S. critical infrastructure, as well as additional mitigation recommendations,

 The National Security Agency (NSA) and CISA have updated their joint
Cybersecurity Technical Report (CTR): Kubernetes Hardening Guide,
originally released in August 2021, based on valuable feedback and inputs from
the cybersecurity community. 

Kubernetes is an open-source system that automates deployment, scaling, and
management of applications run in containers. A container is a runtime
environment that contains a software package and its dependencies. Kubernetes
is often hosted in a cloud environment. The CTR provides recommended
configuration and hardening guidance for setting up and securing a Kubernetes
cluster.

CISA encourages users and administrators to review the updated Kubernetes
Hardening Guide—which includes additional detail and explanations—and apply
the hardening measures and mitigations to manage associated risks.

 Beginning June 1, 2022, the CISSP exam in the Computerized
Adaptive Testing (CAT) format will contain 50 pretest (unscored)
items, which will increase the minimum and maximum number of
items candidates will need to respond to from 100-150 to 125-175 items during
the exam. To allow for these additional items, the maximum exam administration
time will increase from three to four hours.

 

The additional 25 pretest items are evaluated for inclusion
as operational (scored) items in future exams, however, as these pretest items
are indistinguishable from operational (scored) items, candidates should
consider each item carefully and select the best possible answer. Responses
to pretest items do not impact a candidate’s score or the pass/fail result on
their examination.

The CISSP CAT exam currently contains 25 pretest items. The
addition of another 25 enables (ISC)² to continue expanding our item bank to
strengthen the integrity and security of the CISSP for all those who earn the
certification.

There are no other changes to the content of the CISSP exam.
The domains and domain weights contained within the CISSP exam outline have not changed.

CISSP exams scheduled on or after June 1, 2022 will reflect
these changes. If you or your students have questions or need assistance,
please contact examadministration@isc2.org.
