Hidden Cobra or “Lazarus group” are a notorious threat actor from North Korea who active since 2009. While they are probably most known for the infamous Sony Pictures data breach, they are also known for – Operation Kimsuky, Magecart Campaign, HaoBao campaign, Operation AppleJeus, and Operation North Star.

Hidden Cobra has several other aliases like Guardians of Peace, ZINC, NICKEL ACADEMY, etc. The United States Federal Bureau of Investigation has labeled the group as a North Korean “state-sponsored hacking organization.”

Most infamous Hidden Cobra attacks

#1 South Korea Cyberattack

In March 2011, Hidden Cobra launched a series of attacks called “Ten Days of Rain” on specific South Korean media, financial, and critical infrastructure, consisting of sophisticated DDoS attacks. The group continued the attack on March 20, 2013, and targeted three South Korean broadcast companies, financial institutes, and an ISP.

#2 Sony Breach

On November 14, 2014, a Reddit post that stated that Sony Pictures had been hacked by a group identifying themselves as “Guardians of Peace” started showing up. The group had been stealing and leaking a large amount of the company’s data for over a year. The hackers leaked unreleased films, emails, and personal information of over 4,000 employees in the process. Researchers discovered that the group behind the attack was Hidden Cobra.

#3 Various Cryptocurrency Attacks

Around late-2017, North Korea-based groups like Hidden Cobra started a series of cryptocurrency-related attacks. As per reports, the reason behind North Korea’s interest in cryptocurrencies was to find a way to mitigate the various international financial sanctions placed on top of them.

Some examples of the group’s attacks are as follows:

  • February 2017: Stole $7 million from Bithumb, a South Korean exchange.
  • December 2017: A South Korean exchange called “Youbit” was forced to declare bankruptcy after the group robbed them of 17% of their assets.
  • December 2017: NiceHash, a crypto cloud mining company, was hacked for 4,500 BTC.
