Successful exploitation of the vulnerability recently published in ICS-CERT Advisory ICSA-20-042-12 regarding Siemens SIPROTEC 4 and SIPROTEC Compact (reported in the Security & Resilience Update for February 13, 2020) is believed to allow an attacker to reproduce damage caused by Industroyer/CRASHOVERRIDE, the ICS
In its just released 2020 Cloud Misconfigurations Report, cloud security company DivvyCloud notes nearly 33.4 billion records were exposed in breaches due to cloud misconfigurations in 2018 and 2019, amounting to nearly $5 trillion in costs to enterprises globally. From 2018 to 2019, the number of records exposed by cloud misconfigurations rose by 80 percent, as did the total cost to companies associated with those lost records.
Details of AA20-049A published by the U.S. Department of Homeland Security's (DHS's) Cybersecurity and Infrastructure Security Agency (CISA) (reported in the Security & Resilience Update for February 18, 2020), does not seem to represent newly observed activity.
The FBI’s Portland, Oregon office has published an advisory discussing password best practices for protecting yourself and your organization. The advisory also addresses common password mistakes, such as using overly simple passwords, which are easy to an adversary to hack, and reusing passwords, making it possible for a hacker who has obtained the credentials for one account to access others. The advisory advocates for longer, complex passwords that are hard to remember. This can involve combining multiple words into a long string of at least 15 characters.
Reflecting on Recorded Future’s finding that there’s been a dramatic increase in the number of cyber attacks against local governments over the past several years, particularly in terms of ransomware in 2019, IBM’s Security Intelligence writes about why it is that municipal organizations are such attractive targets for threat actors.
The U.S. Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) has published an alert summarizing an incident to which it recently responded. The attack affected the control and communications assets on the operational technology (OT) network of a natural gas compression facility. The incident began with a spearphishing attack that provided access to the information technology (IT) network, from which the attacker pivoted to the OT network. The attacker then deployed ransomware on both networks.
CISA has published an advisory on an improper privilege management vulnerability in Honeywell INNCOM INNControl 3. Versions 3.21 and prior are affected. Successful exploitation of this vulnerability could allow an attacker to escalate user privileges within the INNControl application. Honeywell encourages users to contact an INNCOM sales representative or authorized systems integrator to obtain information on upgrading their system(s) to the latest version.
CISA has published an advisory on a heap-based buffer overflow vulnerability in Emerson OpenEnterprise SCADA Server. OpenEnterprise Server 2.83 is affected if Modbus or ROC Interfaces have been installed and are in use; all versions of OpenEnterprise 3.1 through 3.3.3 are also affected. Successful exploitation of this vulnerability could allow an attacker to execute code on an OpenEnterprise SCADA Server. Emerson recommends all users upgrade to OpenEnterprise 3.3, Service Pack 4 (3.3.4), to resolve this issue. CISA also recommends a series of measures to mitigate the vulnerability.
The U.S. Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA), the FBI, and the Department of Defense have provided new and updated information on malicious cyber activity by the North Korean government. In six new Malware Analysis Reports (MARs), these agencies discuss and provide technical information for Trojan malware variants used by the North Korean government. The new Trojan malware variants include BISTROMATH, SLICKSHOES, HOTCROISSANT, ARTFULPIE, BUFFETLINE, and CROWDEDFLOUNDER.
While there were not a lot of changes and expectations in ICS cybersecurity overall for 2019 and 2020, IBM observed, what it cites as, “explosive growth in OT infrastructure targeting” in 2019.
