EPA and CISA Urge Water Facilities to Disconnect from Internet

December 18, 2024December 18, 2024

EPA and CISA Issue Urgent Advisory on Protecting Water Facilities from Cyber Threats

The Environmental Protection Agency (EPA) and the Cybersecurity Infrastructure and Security Agency (CISA) have released a critical advisory aimed at safeguarding water facilities from cyberattacks targeting human-machine interfaces (HMIs) exposed to the public internet. This advisory, issued on December 13, outlines essential steps water facility operators should take to enhance their cybersecurity posture and protect vital water infrastructure.

Understanding the Cybersecurity Risks for Water Facilities

The advisory highlights the growing threat posed by cybercriminals exploiting HMIs in water and wastewater systems. The EPA and CISA’s 11-point fact sheet urges operators to conduct a thorough inventory of all internet-exposed devices. If feasible, they should disconnect HMIs and any unprotected systems from public access. If disconnection is not an option, securing these devices with strong usernames, passwords, and multi-factor authentication (MFA) is imperative.

Key Recommendations for Water Facility Operators

To mitigate the risk of cyberattacks, the EPA and CISA recommend the following actions:

Conduct an Inventory: Identify all internet-exposed devices within the facility.
Disconnect Devices: If possible, remove HMIs and other vulnerable systems from public access.
Secure Credentials: Implement strong usernames and passwords, changing any factory defaults.
Enable MFA: Use multi-factor authentication for an additional layer of security.
Network Segmentation: Create a demilitarized zone (DMZ) or bastion host to isolate operational technology (OT) networks.

These measures are crucial because HMIs are the gateways to Supervisory Control and Data Acquisition (SCADA) systems, which manage critical operations in water treatment facilities.

The Threat Landscape: Recent Cyberattacks

Recent incidents have demonstrated the vulnerabilities within water facilities. Pro-Russia hacktivists successfully manipulated HMIs, causing disruptions in water systems by altering operational parameters. These breaches allowed attackers to change settings, disable alarms, and lock out utility operators, leading to serious operational challenges.

Expert Insights on Securing Human-Machine Interfaces

Casey Ellis, founder of Bugcrowd, emphasizes that safety-critical control systems should never operate on the public internet. While security measures such as patching and password protection can enhance safety, a single lapse can leave essential services vulnerable to exploitation by sophisticated threat actors.

Venky Raju, Field CTO at ColorTokens, also warns that HMIs are easily discoverable using search engines like Shodan or Censys. These tools can reveal critical information about vulnerable systems that attackers could exploit, such as IP addresses and operating systems.

The Importance of Robust Cybersecurity in Water Facilities

The stakes are high for water facilities, which are responsible for providing clean drinking water 24/7. Itzik Alvas, co-founder and CEO of Entro Security, points out that compromised access to HMIs can lead to unsafe water standards, posing significant risks to public health.

Conclusion: Taking Action to Secure Water Infrastructure

As cyber threats continue to evolve, water facility operators must prioritize cybersecurity to protect their essential services. Implementing the recommendations from the EPA and CISA advisory is a critical step toward safeguarding water infrastructure from potential attacks.

China Blames US for Cyberespionage Targeting Tech Firms

December 19, 2024December 19, 2024

China’s National Computer Network Emergency Response Technical Team (CNCERT/CC) has accused the U.S. of conducting a cyberespionage campaign against Chinese tech companies since May 2023. This alleged campaign targets sectors like intelligent energy and advanced materials, leading to the theft of sensitive trade secrets. The CNCERT/CC claims these attacks reflect a broader strategy reminiscent of previous U.S. allegations against China. The U.S. State Department has yet to respond to these claims, which come amid rising cybersecurity tensions between the two nations. The situation raises significant concerns over international relations and the protection of intellectual property.

North Korean Hackers Target Nuclear Power Sector Workers

December 21, 2024December 21, 2024

Cybersecurity experts at Kaspersky report that North Korean hackers, specifically the Lazarus Group, are increasingly targeting the nuclear power sector. Their sophisticated tactics involve delivering malicious archive files to employees, initiating a multi-layered infection process with various malware types, including downloaders, loaders, and backdoors. This campaign extends from “Operation DreamJob,” where targets are tricked into opening weaponized files. A new malware tool, “CookiePlus,” enhances their evasion strategies, making detection by security systems more challenging. The situation underscores the urgent need for critical industries to strengthen their cybersecurity measures against evolving threats.

Chinese Hackers Breach U.S. Treasury via BeyondTrust API Key

December 31, 2024December 31, 2024

The U.S. Treasury Department has reported a significant cybersecurity breach involving suspected Chinese threat actors, which allowed unauthorized access to computers and unclassified documents. The incident, discovered on December 8, 2024, stemmed from a compromised key used by BeyondTrust, a third-party software provider, enabling attackers to bypass security measures. The Treasury is collaborating with the Cybersecurity and Infrastructure Security Agency (CISA) and the FBI to investigate the state-sponsored attack. BeyondTrust has identified two serious security vulnerabilities and has taken measures to secure its services. This incident highlights the growing sophistication of cyber threats faced by government agencies.

Urgent Alert: Cleo File Transfer Vulnerability Under Attack

December 10, 2024December 10, 2024

Cleo Software users are urged to secure their systems against a serious vulnerability, CVE-2024-50623, affecting Cleo’s LexiCom, VLTransfer, and Harmony software. Reported by Huntress on December 3, 2024, the flaw allows unauthenticated remote code execution due to unrestricted file uploads, enabling attackers to execute arbitrary code. At least ten organizations have already been compromised. Users are advised to update their software, review security settings, and monitor for unusual activities. While Cleo has issued patches, experts warn they may not fully address the vulnerabilities, and ransomware groups are reportedly developing zero-day exploits targeting the software.

North Korean Hackers Linked to Radiant Capital Crypto Theft

December 11, 2024December 11, 2024

Radiant Capital has linked a $50 million cryptocurrency heist in October to North Korea’s cyber threat group, Citrine Sleet, also known as AppleJeus. An investigation with cybersecurity firm Mandiant revealed that attackers used sophisticated tactics, including spoofing a former contractor on Telegram to trick a developer into downloading malware. This allowed them to exploit multi-signature processes on Arbitrum and Binance Smart Chain, despite Radiant’s security measures. The incident highlights the increasing risks of state-sponsored cyberattacks in the cryptocurrency sector, emphasizing the urgent need for enhanced security protocols in decentralized finance.
