Notorious North Korean Hacking Group Kimsuky Gets Hacked, Revealing Deep Secrets

The infamous Kimsuky, a notorious North Korean state-sponsored threat actor, has been hit by a daring cyber attack that has left the group reeling. The perpetrator behind the breach, who goes by the pseudonym Saber / cyb0rg, claims to be an "artist" rather than a cybercriminal. The hacked database, weighing in at 8.9GB, has been shared on the "Distributed Denial of Secrets" website, exposing some of Kimsuky's most closely guarded secrets.

The contents of the leak are nothing short of astonishing. The database contains logs, tools, and infrastructure used by the group, providing a glimpse into their tactics, techniques, and procedures (TTPs). This includes phishing logs that reveal an attack against the Defense Counterintelligence Command, South Korea's military intelligence security agency, as well as targeted domains and archives with the complete source code of South Korea's Ministry of Foreign Affairs email platform.

The haul also includes a list of South Korean university professors, a toolkit for building phishing sites, Cobalt Strike loaders, and more. This treasure trove of information provides a unique insight into Kimsuky's modus operandi and the extent of their cyber-espionage campaigns.

A Brief History of Kimsuky

Kimsuky first emerged in 2012, and since then, they have been credited with numerous attacks against government agencies, think tanks, research institutions, and media outlets. The group is particularly focused on Korean Peninsula affairs, nuclear policy, and foreign relations.

The Hacker's Letter: A Scathing Critique of Kimsuky

In a letter accompanying the leak, Saber / cyb0rg slammed Kimsuky for advancing state agendas. "Kimsuky, you are not a hacker," the letter read. "You are driven by financial greed, to enrich your leaders, and to fulfill their political agenda." The letter continued, "You steal from others and favor your own. You value yourself above the others: You are morally perverted."

The Impact of the Leak on Kimsuky

While the leak is a commendable effort, it's unlikely to completely stop Kimsuky, as they possess formidable resources. However, the exposure of many tools and methods may slow the group down, expose current campaigns, and force them to start from scratch in some cases.
