Hey look, a real photo of a hacker

This is the best summary I could come up with:

North Korea-backed hackers are once again targeting security researchers with a zero-day exploit and related malware in an attempt to infiltrate computers used to perform sensitive investigations involving cybersecurity.

Similar to the previous campaign TAG reported on, North Korean threat actors used social media sites like X (formerly Twitter) to build rapport with their targets.

Once a relationship was developed with a targeted researcher, the threat actors sent a malicious file that contained at least one 0-day in a popular software package.

Upon successful exploitation, the shellcode conducts a series of anti-virtual machine checks and then sends the collected information, along with a screenshot, back to an attacker-controlled command and control domain.

The post said that in addition to exploiting the current zero-day, the same hacking group appears to be sharing software that also targets researchers.

The researchers urged anyone who has run the software to “ensure your system is in a known clean state, likely requiring a reinstall of the operating system.” The post includes file hashes, IP addresses, and other data people can use to discern if they've been targeted.

Can someone tell me what 0-day is?
