1. US, South Korea discuss new mechanisms against North Korean threats while announcing National Cybersecurity Strategy
A high-ranking officer in the United States Department of Defense disclosed on Thursday that the U.S. is discussing new mechanisms with the South Korean government to deter North Korean nuclear threats. On the same day, the U.S. Secretary of Defense Lloyd Austin asserted his intention to respond to North Korean provocations in coordination with the Republic of Korea. In the meantime, the White House reidentified the North Korean government as a malicious actor in cyberspace while announcing the National Cybersecurity Strategy.
“What we have been focused on over the last several months, and particularly since President Yoon came into office, is restoring elements of the alliance and elements of deterrence in the U.S. extended deterrence in ways that are in some instances unprecedented in response to what we are seeing out of the North,” said Ely Rattner, the Assistant Secretary of Defense for Indo-Pacific Security Affairs, during a discussion hosted by the Hudson Institute, referring to the working relationship between the U.S. and South Korean defense departments. Rattner further mentioned that the two countries are discussing “new consultive mechanisms” to enhance their understanding of strategic operations. “We have also been doing site visits with senior Korean officials to go to the U.S. strategic sites to actually see and understand and meet with folks there about what we are talking about in a very concrete way,” added Rattner.
On March 2, the Biden administration announced the National Cybersecurity Strategy, recognizing the importance of cybersecurity for the economy and national defense. The strategy indicates that the governments of China, Russia, Iran, and North Korea are malicious actors in cyberspace and are “aggressively using advanced cyber capabilities” to achieve their goals which are mostly against international norms. Emphasizing its responsibilities and the need for collaboration to defend cyberspace, the U.S. government suggested five pillars of its strategy as below.
― Defend critical infrastructure
― Disrupt and dismantle threat actors
― Shape market forces to drive security and resilience
― Invest in a resilient future
― Forge international partnerships to pursue shared goals
2. North Korea hacked activist group over propaganda leaflets
North Korea linked hackers stole the information of an activist group in South Korea who have been floating anti-North Korean propaganda leaflets across the border. The attack, which was conducted last September, was revealed on Friday by South Korean lawmaker Yoon Sang-bum, who received the information from the National Intelligence Service.
According to a document submitted by the NIS, the leaked data included detailed information, such as the profile photos and the dates and locations related to the group’s activities on propaganda leaflets. The nation’s intelligence agency concluded that this data could be used to identify specific individuals and contacted the police to provide personal protection.
The attack was conducted a month after the North Korean leader’s sister Kim Yo-jung had harshly criticized the leaflets, blaming them for the country’s covid-19 outbreak. Activist groups have been sending propaganda leaflets by balloons across the border, raising tension between both countries. In a statement last August, she stressed the need for deadly retaliation against those activities.

Are you someone who always forgets passwords and finds yourself struggling to reset login information? Welcome to the club! It has only been more and more difficult to remember every single password for different types of online services. Some of us have dealt with this stress by reusing the same passwords for various accounts. However, this action carries significant risks to our lives online and plants the seeds of privacy exposure.
According to research by the cybersecurity industry, the average person reuses the same password as many as 14 times. Moreover, 72% of individuals reuse passwords in their personal lives, and 49% of employees only slightly adjust their passwords when they are forced to change their password at work by adding a digit or a character to the original passwords.
