Hey there, I'm Ting, and welcome to Cyber Sentinel: Beijing Watch. Today, January 2, 2025, we're diving into the latest Chinese cyber activities that have been making waves in US security.

Let's get straight to it. The US Treasury Department has just confirmed a major breach, with cybercriminals backed by the Chinese state government hacking into federal workstations and accessing unclassified documents. According to Nicole Sganga, CBS News Homeland Security and Justice reporter, the hackers used a stolen key from a third-party vendor called BeyondTrust to override the security of their cloud-based system[1].

This isn't the first time we've seen Chinese-linked cyberattacks. Remember Volt Typhoon, the notorious group that targeted at least eight US telecommunications companies, compromising metadata of hundreds of thousands, possibly millions, of Americans? The FBI and Cybersecurity and Infrastructure Security Agency (CISA) have been investigating this campaign, revealing a broad and significant cyber espionage operation[2][4].

But what's new is the sophistication of these attacks. The use of MIPS-based malware and webshells like fy.sh allows Volt Typhoon to maintain persistent access and control, making cleanup efforts a nightmare. FBI Director Christopher Wray has warned that these attacks are not just about espionage but also about preparing to destroy or degrade critical infrastructure[2].

So, what can we do? First, it's crucial to prioritize visibility into the network edge and implement continuous monitoring and logging for unusual behavior. Thomas from Infosecurity Magazine advises adopting a rigorous round-the-clock vulnerability management program and segmenting networks to prevent lateral movement[5].

But here's the thing: nation-state actors are getting smarter. They're using tools and services developed by cybercriminals and setting up front companies to hide their malicious activities. Danowski from Infosecurity Magazine notes that China is likely to focus on flaws in the network edge in 2025, making it essential to patch edge devices quickly after vulnerabilities are disclosed[5].

In conclusion, the past few days have shown us that Chinese cyber activities are becoming increasingly sophisticated and targeted. It's time to step up our game. Stay vigilant, and remember, in the world of cybersecurity, it's always better to be safe than sorry. That's it for today's Cyber Sentinel: Beijing Watch. Stay tuned for more updates.
