4. MITIGATIONS
For more information, please refer to ABB’s Cybersecurity Advisory 2NGA002579. It provides a comprehensive mapping of mitigation applicability in relation to each individual vulnerability listed.
ABB recommends the following mitigations:

Obtain a cellular private access point (APN). A dedicated private cellular access point and respective SIM card subscriptions can be requested from the cellular service provider. This service doesn’t expose the traffic between remote sites and the main site to the Internet but rather uses the cellular operator’s private wide area network (WAN). Therefore, the ARM600 wouldn’t need open ports to the Internet.
Avoid exposing any system component to the Internet. If the ARM600 must be exposed to the Internet, only the VPN port should be opened towards the Internet (e.g., Patrol management connections can be configured to use a VPN tunnel, and remote administration connections can be implemented using an OpenVPN PC-client).
The ARM600 system is by default not dependent on the name service (DNS). If the name service is not used in the system, the name service port (TCP/UDP Port 53) can be blocked by a firewall.
Perform firewall configuration using the ‘allowlisting’ principle, explicitly allowing only the required ports and protocols and blocking all other traffic.
Filter specific ICMP packets from external systems (ICMP type 13 and 14) using a firewall to avoid exposing the system time.
If the Internet is used as a WAN medium for carrying VPN tunnels, use a demilitarized zone (DMZ) for terminating connections from the Internet. Remote connections should terminate in the DMZ network, which would be segregated from other networks by a firewall. The ARM600 server should be located in this DMZ.
Change the default user credentials of ARM600 and Arctic wireless gateways into non-defaults and use complex non-guessable passwords with special characters. Do not reuse passwords within the system.
Use administrator (i.e., root user) privileges only when required by the task.
Supporting systems, such as PCs used for configuration, should be frequently updated. If possible, use dedicated site PCs for upgrading and engineering purposes. At a minimum, PCs should be investigated by running a full virus scan with recently updated signature files before introducing the PC to the OT system. Any data, such as device configurations and firmware update files, should be virus scanned prior to transferring to the Arctic system.
Introduce a backup policy to ensure periodic backups and backup revision numbering. Consider the following:a. Check that the entire system has backups available from all applicable parts.b. Store the backups in a safe place (e.g. in an encrypted storage), restricted by role-based access control mechanisms.c. Ensure the security of the configuration PCs that may have local copies of device configurations.d. Validate the backups to ensure they are working.
Follow cyber security best practices for installation, operation, and decommissioning as described in the product’s cyber security deployment guideline and user manual.
Use continuous monitoring (e.g., intrusion detection/prevention tools) to detect anomalies in the system.
Consider hardening the system according to the following:a. Remove any unnecessary communication links in the system.b. If possible, close unused physical ports.c. Open only the necessary TCP/UDP ports in the configuration.d. Remove all unnecessary user accounts.e. Restrict traffic by firewall.f. Allow the traffic only from/to necessary hosts’ IP addresses (i.e., define both source and destination in the firewall rules, where possible).g. Define client IP address as allowed address in SCADA communication protocols, if such configuration is supported.h. Remove or deactivate all unused processes, communication ports, and services where possible.i. Use physical access controls to the system installations (e.g., to server rooms and device cabinets).
In ARM600SW installations, avoid servers with AMD processors vulnerable to the following: CVE-2021-26401, CVE-2023-20569 and CVE-2023-20593.
Avoid using AX88179_178A chipset-based USB-to-ethernet devices.

ABB strongly recommends the following (non-exhaustive) list of cyber security practices for any installation of software-related ABB products:

Isolate special purpose networks (e.g., for automation systems) and remote devices behind firewalls and separate them from any general purpose network (e.g., office or home networks).
Install physical controls to ensure no unauthorized personnel can access the devices, components, peripheral equipment, and networks.
Never connect programming software or computers containing programming software to any network other than the network intended for the devices.
Scan all data imported into the environment before use to detect potential malware infections.
Minimize network exposure for all applications and endpoints to ensure they are not accessible from the Internet unless they are designed for such exposure and the intended use requires it.
Ensure all nodes are always up to date with installed software, operating system, and firmware patches, as well as anti-virus and firewall updates.
When remote access is required, use secure methods, such as virtual private networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.

4. MITIGATIONS

For more information, please refer to ABB’s Cybersecurity Advisory 2NGA002579. It provides a comprehensive mapping of mitigation applicability in relation to each individual vulnerability listed.

ABB recommends the following mitigations:

1. Obtain a cellular private access point (APN). A dedicated private cellular access point and respective SIM card subscriptions can be requested from the cellular service provider. This service doesn’t expose the traffic between remote sites and the main site to the Internet but rather uses the cellular operator’s private wide area network (WAN). Therefore, the ARM600 wouldn’t need open ports to the Internet.
2. Avoid exposing any system component to the Internet. If the ARM600 must be exposed to the Internet, only the VPN port should be opened towards the Internet (e.g., Patrol management connections can be configured to use a VPN tunnel, and remote administration connections can be implemented using an OpenVPN PC-client).
3. The ARM600 system is by default not dependent on the name service (DNS). If the name service is not used in the system, the name service port (TCP/UDP Port 53) can be blocked by a firewall.
4. Perform firewall configuration using the ‘allowlisting’ principle, explicitly allowing only the required ports and protocols and blocking all other traffic.
5. Filter specific ICMP packets from external systems (ICMP type 13 and 14) using a firewall to avoid exposing the system time.
6. If the Internet is used as a WAN medium for carrying VPN tunnels, use a demilitarized zone (DMZ) for terminating connections from the Internet. Remote connections should terminate in the DMZ network, which would be segregated from other networks by a firewall. The ARM600 server should be located in this DMZ.
7. Change the default user credentials of ARM600 and Arctic wireless gateways into non-defaults and use complex non-guessable passwords with special characters. Do not reuse passwords within the system.
8. Use administrator (i.e., root user) privileges only when required by the task.
9. Supporting systems, such as PCs used for configuration, should be frequently updated. If possible, use dedicated site PCs for upgrading and engineering purposes. At a minimum, PCs should be investigated by running a full virus scan with recently updated signature files before introducing the PC to the OT system. Any data, such as device configurations and firmware update files, should be virus scanned prior to transferring to the Arctic system.
10. Introduce a backup policy to ensure periodic backups and backup revision numbering. Consider the following:
    a. Check that the entire system has backups available from all applicable parts.
    b. Store the backups in a safe place (e.g. in an encrypted storage), restricted by role-based access control mechanisms.
    c. Ensure the security of the configuration PCs that may have local copies of device configurations.
    d. Validate the backups to ensure they are working.
11. Follow cyber security best practices for installation, operation, and decommissioning as described in the product’s cyber security deployment guideline and user manual.
12. Use continuous monitoring (e.g., intrusion detection/prevention tools) to detect anomalies in the system.
13. Consider hardening the system according to the following:
    a. Remove any unnecessary communication links in the system.
    b. If possible, close unused physical ports.
    c. Open only the necessary TCP/UDP ports in the configuration.
    d. Remove all unnecessary user accounts.
    e. Restrict traffic by firewall.
    f. Allow the traffic only from/to necessary hosts’ IP addresses (i.e., define both source and destination in the firewall rules, where possible).
    g. Define client IP address as allowed address in SCADA communication protocols, if such configuration is supported.
    h. Remove or deactivate all unused processes, communication ports, and services where possible.
    i. Use physical access controls to the system installations (e.g., to server rooms and device cabinets).
14. In ARM600SW installations, avoid servers with AMD processors vulnerable to the following: CVE-2021-26401, CVE-2023-20569 and CVE-2023-20593.
15. Avoid using AX88179_178A chipset-based USB-to-ethernet devices.

ABB strongly recommends the following (non-exhaustive) list of cyber security practices for any installation of software-related ABB products:

• Isolate special purpose networks (e.g., for automation systems) and remote devices behind firewalls and separate them from any general purpose network (e.g., office or home networks).
• Install physical controls to ensure no unauthorized personnel can access the devices, components, peripheral equipment, and networks.
• Never connect programming software or computers containing programming software to any network other than the network intended for the devices.
• Scan all data imported into the environment before use to detect potential malware infections.
• Minimize network exposure for all applications and endpoints to ensure they are not accessible from the Internet unless they are designed for such exposure and the intended use requires it.
• Ensure all nodes are always up to date with installed software, operating system, and firmware patches, as well as anti-virus and firewall updates.
• When remote access is required, use secure methods, such as virtual private networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.

CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.

Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.

Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.

3.2 VULNERABILITY OVERVIEW

3.2.1 UNCONTROLLED RESOURCE CONSUMPTION CWE-400

The integrated ICMP service of the network stack of affected devices can be forced to exhaust its available memory resources when receiving specially crafted messages targeting IP fragment re-assembly. This could allow an unauthenticated remote attacker to cause a temporary denial-of-service condition of the ICMP service, other communication services are not affected. Affected devices will resume normal operation after the attack terminates.

CVE-2024-23814 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been assigned; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).

A CVSS v4 score has also been calculated for CVE-2024-23814. A base score of 6.9 has been calculated; the CVSS vector string is (CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N).

​President Trump last week revoked security clearances for Chris Krebs, the former director of the Cybersecurity and Infrastructure Security Agency (CISA) who was fired by Trump after declaring the 2020 election the most secure in U.S. history. The White House memo, which also suspended clearances for other security professionals at Krebs’s employer SentinelOne, comes as CISA is facing huge funding and staffing cuts. 

President Trump last week revoked security clearances for Chris Krebs, the former director of the Cybersecurity and Infrastructure Security Agency (CISA) who was fired by Trump after declaring the 2020 election the most secure in U.S. history. The White House memo, which also suspended clearances for other security professionals at Krebs’s employer SentinelOne, comes as CISA is facing huge funding and staffing cuts.

The extraordinary April 9 memo directs the attorney general to investigate Chris Krebs (no relation), calling him “a significant bad-faith actor who weaponized and abused his government authority.”

The memo said the inquiry will include “a comprehensive evaluation of all of CISA’s activities over the last 6 years and will identify any instances where Krebs’ or CISA’s conduct appears to be contrary to the administration’s commitment to free speech and ending federal censorship, including whether Krebs’ conduct was contrary to suitability standards for federal employees or involved the unauthorized dissemination of classified information.”

CISA was created in 2018 during Trump’s first term, with Krebs installed as its first director. In 2020, CISA launched Rumor Control, a website that sought to rebut disinformation swirling around the 2020 election.

That effort ran directly counter to Trump’s claims that he lost the election because it was somehow hacked and stolen. The Trump campaign and its supporters filed at least 62 lawsuits contesting the election, vote counting, and vote certification in nine states, and nearly all of those cases were dismissed or dropped for lack of evidence or standing.

When the Justice Department began prosecuting people who violently attacked the U.S. Capitol on January 6, 2021, President Trump and Republican leaders shifted the narrative, claiming that Trump lost the election because the previous administration had censored conservative voices on social media.

Incredibly, the president’s memo seeking to ostracize Krebs stands reality on its head, accusing Krebs of promoting the censorship of election information, “including known risks associated with certain voting practices.” Trump also alleged that Krebs “falsely and baselessly denied that the 2020 election was rigged and stolen, including by inappropriately and categorically dismissing widespread election malfeasance and serious vulnerabilities with voting machines” [emphasis added].

Krebs did not respond to a request for comment. SentinelOne issued a statement saying it would cooperate in any review of security clearances held by its personnel, which is currently fewer than 10 employees.

Krebs’s former agency is now facing steep budget and staff reductions. The Record reports that CISA is looking to remove some 1,300 people by cutting about half its full-time staff and another 40% of its contractors.

“The agency’s National Risk Management Center, which serves as a hub analyzing risks to cyber and critical infrastructure, is expected to see significant cuts, said two sources familiar with the plans,” The Record’s Suzanne Smalley wrote. “Some of the office’s systematic risk responsibilities will potentially be moved to the agency’s Cybersecurity Division, according to one of the sources.”

CNN reports the Trump administration is also advancing plans to strip civil service protections from 80% of the remaining CISA employees, potentially allowing them to be fired for political reasons.

The Electronic Frontier Foundation (EFF) urged professionals in the cybersecurity community to defend Krebs and SentinelOne, noting that other security companies and professionals could be the next victims of Trump’s efforts to politicize cybersecurity.

“The White House must not be given free reign to turn cybersecurity professionals into political scapegoats,” the EFF wrote. “It is critical that the cybersecurity community now join together to denounce this chilling attack on free speech and rally behind Krebs and SentinelOne rather than cowering because they fear they will be next.”

However, Reuters said it found little sign of industry support for Krebs or SentinelOne, and that many security professionals are concerned about potentially being targeted if they speak out.

“Reuters contacted 33 of the largest U.S. cybersecurity companies, including tech companies and professional services firms with large cybersecurity practices, and three industry groups, for comment on Trump’s action against SentinelOne,” wrote Raphael Satter and A.J. Vicens. “Only one offered comment on Trump’s action. The rest declined, did not respond or did not answer questions.”

CYBERCOM-PLICATIONS

On April 3, President Trump fired Gen. Timothy Haugh, the head of the National Security Agency (NSA) and the U.S. Cyber Command, as well as Haugh’s deputy, Wendy Noble. The president did so immediately after meeting in the Oval Office with far-right conspiracy theorist Laura Loomer, who reportedly urged their dismissal. Speaking to reporters on Air Force One after news of the firings broke, Trump questioned Haugh’s loyalty.

Virginia Senator Mark Warner, the top Democrat on the Senate Intelligence Committee, called it inexplicable that the administration would remove the senior leaders of NSA-CYBERCOM without cause or warning, and risk disrupting critical ongoing intelligence operations.

“It is astonishing, too, that President Trump would fire the nonpartisan, experienced leader of the National Security Agency while still failing to hold any member of his team accountable for leaking classified information on a commercial messaging app – even as he apparently takes staffing direction on national security from a discredited conspiracy theorist in the Oval Office,” Warner said in a statement.

On Feb. 28, The Record’s Martin Matishak cited three sources saying Defense Secretary Pete Hegseth ordered U.S. Cyber Command to stand down from all planning against Russia, including offensive digital actions. The following day, The Guardian reported that analysts at CISA were verbally informed that they were not to follow or report on Russian threats, even though this had previously been a main focus for the agency.

A follow-up story from The Washington Post cited officials saying Cyber Command had received an order to halt active operations against Russia, but that the pause was intended to last only as long as negotiations with Russia continue.

The Department of Defense responded on Twitter/X that Hegseth had “neither canceled nor delayed any cyber operations directed against malicious Russian targets and there has been no stand-down order whatsoever from that priority.”

But on March 19, Reuters reported several U.S. national security agencies have halted work on a coordinated effort to counter Russian sabotage, disinformation and cyberattacks.

“Regular meetings between the National Security Council and European national security officials have gone unscheduled, and the NSC has also stopped formally coordinating efforts across U.S. agencies, including with the FBI, the Department of Homeland Security and the State Department,” Reuters reported, citing current and former officials.

TARIFFS VS TYPHOONS

President’s Trump’s institution of 125% tariffs on goods from China has seen Beijing strike back with 84 percent tariffs on U.S. imports. Now, some security experts are warning that the trade war could spill over into a cyber conflict, given China’s successful efforts to burrow into America’s critical infrastructure networks.

Over the past year, a number of Chinese government-backed digital intrusions have come into focus, including a sprawling espionage campaign involving the compromise of at least nine U.S. telecommunications providers. Dubbed “Salt Typhoon” by Microsoft, these telecom intrusions were pervasive enough that CISA and the FBI in December 2024 warned Americans against communicating sensitive information over phone networks, urging people instead to use encrypted messaging apps (like Signal).

The other broad ranging China-backed campaign is known as “Volt Typhoon,” which CISA described as “state-sponsored cyber actors seeking to pre-position themselves on IT networks for disruptive or destructive cyberattacks against U.S. critical infrastructure in the event of a major crisis or conflict with the United States.”

Responsibility for determining the root causes of the Salt Typhoon security debacle fell to the Cyber Safety Review Board (CSRB), a nonpartisan government entity established in February 2022 with a mandate to investigate the security failures behind major cybersecurity events. But on his first full day back in the White House, President Trump dismissed all 15 CSRB advisory committee members — likely because those advisers included Chris Krebs.

Last week, Sen. Ron Wyden (D-Ore.) placed a hold on Trump’s nominee to lead CISA, saying the hold would continue unless the agency published a report on the telecom industry hacks, as promised.
