This case represents one of the largest North Korean IT worker fraud schemes ever prosecuted by the US DoJ, in which Chapman received a sentence of 102 months (8 years) in prison,…

Every new job seeker’s nightmare — you need a resume, but you have no work experience to put on it. When you’re just beginning your professional life, this can be very frustrating. The resume is what gets your foot in the door and places you in the interview room. You need it to be good to be considered for jobs, but without any experience, it can feel like a losing battle. I understand the struggles, but here’s a different perspective: You feel there’s “nothing” to put on your resume> Work experience is not the only thing that matters. You have…

Communication systems have evolved from simple bit transmission to intelligent information sharing. Traditional systems focus on moving raw data from point A to point B as reliably as possible. Now, with the explosion of machine-to-machine communication in IoT devices, autonomous systems, and smart infrastructure, we’re hitting a fundamental bottleneck. Modern networks are drowning in unnecessary data. But machines don’t need every bit of information that traditional systems transmit.  Let’s take a look at the following security monitoring interaction: Security Camera: Spots someone walking around in a restricted area during off-hours and captures a high-resolution video frame of size 5 MB…

The new leader of the powerful House Homeland Security Committee is committed to meeting a tight deadline for reauthorizing a pivotal cybersecurity information sharing law, but wants to see “some changes” to the statute, according to a top aide. Questions around the process for reauthorizing the Cybersecurity Information Sharing Act of 2015 have developed into a crucial early test for new House Homeland Security Committee Chairman Andrew Garbarino (R-N.Y.). He was selected to replace former Chairman Mark Green (R-Tenn.) this week. As chairman of the committee’s cybersecurity and infrastructure protection subcommittee, Garbarino called reauthorizing CISA 2015 a “top priority.” The…

As IT and OT systems continue to converge and redefine industrial strategy, outdated OT cybersecurity training is falling behind the pace and complexity of modern threats. Operators were once trained to optimize uptime above all, but are now positioned at the front lines of a cyber battlefield, a place where attacks look like equipment failure and where process safety measures are taken away without any notice. However, too often, cybersecurity training is reduced to a compliance or box-ticking exercise, far removed from the real-world pressure and complexity of industrial environments.  Adversaries are increasingly becoming more focused on targeting OT environments…

Christina Marie Chapman, a 50-year-old woman from Arizona, was sentenced to 102 months in prison after pleading guilty to her involvement in a scheme that enabled North Korean IT workers to infiltrate 309 U.S. companies. Chapman was charged in May 2024, together with Ukrainian citizen Oleksandr Didenko, with aggravated identity theft, conspiracy to defraud the United States, and conspiracy to commit money laundering, wire fraud, identity fraud, and bank fraud. Didenko also ran an online platform known as UpWorkSell (which was seized by the DOJ) that provided services allowing North Koreans to use false identities while hunting for remote IT…
