The latest: CrowdStrike said its software observed an attack that exploited the Log4j flaw in software from VMware.

  • The attack came from a China-based group dubbed Aquatic Panda that has been conducting intelligence gathering and industrial espionage, CrowdStrike said.

The big picture: Some security experts, including Cybersecurity and Infrastructure Security Agency (CISA) head Jen Easterly, have called the flaw among the worst they have ever seen.

  • Experts have told Axios the Log4j flaw is especially pernicious because the open source software is widely used within business software and networking gear — often without companies even knowing it is being used. On top of that, the flaw is easily exploited and can provide extensive access.

Be smart: CISA is maintaining a list of known affected products here.
