A financially motivated threat actor is actively scouring the internet for unprotected Apache NiFi instances to covertly install a cryptocurrency miner and facilitate lateral movement.
The findings come from the SANS Internet Storm Center (ISC), which detected a spike in HTTP requests for “/nifi” on May 19, 2023.
“Persistence is achieved via timed processors or entries to cron,” said Dr.

Cybersecurity researchers have found « backdoor-like behavior » within Gigabyte systems, which they say enables the UEFI firmware of the devices to drop a Windows executable and retrieve updates in an unsecure format.
Firmware security firm Eclypsium said it first detected the anomaly in April 2023. Gigabyte has since acknowledged and addressed the issue.

Microsoft has shared details of a now-patched flaw in Apple macOS that could be abused by threat actors with root access to bypass security enforcements and perform arbitrary actions on affected devices.
Specifically, the flaw – dubbed Migraine and tracked as CVE-2023-32369 – could be abused to get around a key security measure called System Integrity Protection (SIP), or “rootless,” which

Finding threat actors before they find you is key to beefing up your cyber defenses. How to do that efficiently and effectively is no small task – but with a small investment of time, you can master threat hunting and save your organization millions of dollars.
Consider this staggering statistic. Cybersecurity Ventures estimates that cybercrime will take a $10.5 trillion toll on the global
