Talk deployment
ESET researchers have uncovered a treasure trove of clues, analyzing 6,044 Slack messages and 3,005 Discord messages that reveal the covert operations of a China-linked APT group, dubbed GopherWhisper, which has been active since at least 2023. The recovered logs provide a rare glimpse into the group's tactics, thanks to hardcoded credentials in Go-based backdoors that gave investigators access to the group's command and control channels.
In today's hyper-fast cyber threat landscape, operating at machine speed is no longer a choice - it's a necessity, as expert Tom Kellermann warns, highlighting the urgent need for advanced threat intelligence to combat AI-driven attacks.
The old security measures are no longer enough - a 'passed' audit only tells you where you've been, not where you are now, in a threat landscape rapidly changed by AI-driven attacks. Advanced AI tools can now discover and exploit weaknesses at unprecedented speeds and scales, outpacing traditional security methods.
