For providers

Nearly 20 water, energy, and heating providers across Ukraine were noted by the country's Computer Emergency Response Team to have their information and communications systems targeted by Russian state-backed advanced persistent threat operation Sandworm, also known as APT44, Voodoo Bear, BlackEnergy, and Seashell Blizzard, last month, reports BleepingComputer.

Open-source DevOps software project GitLab has also been impacted by the same security issue in GitHub comments that has been exploited by threat actors through Microsoft repository-linked URLs to facilitate the distribution of malware that was made to seem to originate from credible entities' official source code repositories, according to BleepingComputer.

The State Department can now deny entrance to the US for individuals accused of profiting from spyware-related human rights abuses, and their immediate family members.

The infamous Russian threat actor has created a custom tool called GooseEgg to exploit CVE-2022-38028 in cyber-espionage attacks against targets in Ukraine, Western Europe, and North America.

Like many similar frameworks and languages, Struts 2 has a "developer mode" (devmode) offering additional features to aid debugging. Error messages will be more verbose, and the devmode includes an OGNL console. OGNL, the Object-Graph Navigation Language, can interact with Java, but in the end, executing OGNL results in arbitrary code execution. This OGNL console resembles a "web shell" built into devmode.

CISA has added one new vulnerability to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. CVE-2022-38028 Microsoft Windows Print Spooler Privilege Escalation Vulnerability These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information. Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.

CISA released two Industrial Control Systems (ICS) advisories on April 23, 2024. These advisories provide timely information about current security issues, vulnerabilities, and exploits surrounding ICS. ICSA-24-051-03 Mitsubishi Electric Electrical Discharge Machines (Update A) ICSA-24-067-01 Chirp Systems Chirp Access (Update A) CISA encourages users and administrators to review the newly released ICS advisories for technical details and mitigations.

State-sponsored groups are targeting critical vulnerabilities in virtual private network (VPN) gateways, firewall appliances, and other edge devices to make life difficult for incident responders, who rarely have visibility into the devices.

Security pros must always remember that we are custodians of the digital realm and it’s our job to keep people safe.
