Cracking Today’s Cyber Chaos: June 16, 2025, Cybersecurity Events.

Yo, hackers and cyber nerds! It’s your favorite part-time pen tester and full-time cybersecurity obsessive, back to unpack the digital dumpster fire that is June 16, 2025. As someone who spends their days breaking into systems (ethically, of course) and their nights chasing the latest threat intel, I’m pumped to dive into today’s freshest cybersecurity events. From Chinese APTs exploiting zero-days to ransomware gangs flexing on Linux, AI-powered malware dodging defenses, and supply chain attacks hitting npm, the internet is popping off. So, boot up your Kali Linux, crack open a Monster Energy, and let’s dissect these threats with a hacker’s mindset—complete with pen testing tips to keep you sharp.

Today’s Threat Landscape: June 16, 2025, in Focus

The cyber world moves fast, and June 16 is no exception. My feeds are blowing up with breaking news about targeted attacks, sneaky malware, and scams that make my pen tester heart race (and my sysadmin side cringe). Here’s the rundown of what’s hitting the wires today, filtered through the eyes of someone who lives to exploit—and secure—systems.

Chinese APT Targets U.S. Cities with Zero-Day Exploit

Kicking things off, a Chinese advanced persistent threat (APT) group, dubbed PurpleHaze, made headlines today for exploiting a zero-day vulnerability in Cityworks software, targeting U.S. municipal infrastructure. Reported by @EverPendragon on X, this attack aimed to compromise critical systems like water utilities and traffic management. As a pen tester, zero-days are my holy grail—finding one feels like hitting the jackpot, but defending against them is a nightmare.

This attack screams nation-state sophistication. PurpleHaze likely used custom exploits and stealthy persistence to blend into municipal networks. I’ve seen similar tactics in red team gigs, where I’d chain a zero-day with lateral movement to own a network. James Knight, Senior Principal at Digital Warfare, nailed it: “Pen testers must mirror APTs like PurpleHaze, using tools like Shodan to map exposed infrastructure and custom payloads to simulate real-world threats.” Their IoT security case studies are a goldmine for learning how to scope critical systems.

Pen Testing Tip: Hunting Zero-Days

• Shodan Recon: Use Shodan to scan for exposed Cityworks instances or similar software in your client’s environment. Look for unpatched versions matching CVE patterns.
• Metasploit Magic: Metasploit often gets rapid updates for zero-days. Spin up a lab and test exploits against a Cityworks-like setup to understand attack vectors.
• Burp Suite for APIs: Many zero-days target APIs. Use Burp Suite to intercept and fuzz API calls, hunting for misconfigs or injection flaws.

Pro tip: Always check for unpatched software during engagements. I once found a client running a five-year-old version of a CMS—low-hanging fruit for any APT.

BERT Ransomware Goes Cross-Platform with ELF Files

Ransomware gangs are stepping up their game, and today’s news about BERT ransomware is proof. According to @fridaysecurity on X, BERT now targets Linux machines using weaponized ELF (Executable and Linkable Format) files, a nasty upgrade from its Windows-only days. This cross-platform pivot makes BERT a threat to servers, cloud instances, and even IoT devices running Linux.

As a pen tester, I’ve simulated ransomware attacks to stress-test client defenses, and BERT’s evolution reminds me of a gig where I encrypted a test server with a custom payload. The client’s face when they saw their “critical” server locked? Priceless—and a wake-up call. BERT’s ELF trickery means pen testers need to think beyond Windows.

Pen Testing Tip: Simulating Ransomware

• Mimikatz for Creds: Use Mimikatz to harvest credentials and simulate lateral movement, mimicking how BERT spreads.
• Custom ELF Payloads: Craft a benign ELF file in a lab to test Linux endpoint detection. Tools like msfvenom in Metasploit can generate these for controlled tests.
• Phishing Drills: Since ransomware often starts with phishing, use the Social-Engineer Toolkit (SET) to test employee awareness with fake ransom demands.

BERT’s rise underscores the need for cross-platform defenses. If your client’s Linux servers aren’t hardened, you’re begging for trouble.

HijackLoader and DeerStealer: AI-Powered Malware Duo

Today’s malware scene got spicier with @fridaysecurity reporting on HijackLoader and DeerStealer, a new duo bypassing defenses with AI-driven obfuscation. These baddies surge through networks, stealing data and evading EDR (Endpoint Detection and Response) tools by dynamically rewriting their code. As someone who’s used AI to fuzz vulnerabilities, I’m both impressed and horrified by how attackers are leveraging it.

In one pen test, I used an AI-powered tool to generate polymorphic payloads that slipped past a client’s fancy EDR. The look on their SOC team’s face when I showed them the exfiltrated data? Pure panic. HijackLoader and DeerStealer are doing this at scale, and it’s a game-changer.

Pen Testing Tip: Testing AI-Driven Malware

• Fuzzing with AFL++: Use AI-driven fuzzers like AFL++ to stress-test applications for vulnerabilities that AI malware might exploit.
• Cobalt Strike for Evasion: Simulate AI malware with Cobalt Strike’s malleable C2 profiles to test EDR bypass techniques.
• Monitor Anomalies: Train clients to spot unusual network traffic using tools like Zeek or Suricata, as AI malware often leaves subtle traces.

AI-driven attacks are the future, and pen testers need to get comfy with AI tools to stay ahead.

Supply Chain Scare: npm Packages Hit Again

Supply chain attacks are my personal boogeyman, and today’s news about npm packages didn’t help. Posts on X hint at a new wave of malicious npm libraries, echoing last week’s GlueStack attack that infected millions. While details are still emerging, the pattern is familiar: compromised contributor accounts pushing tampered packages that steal creds or mine crypto.

I’ve been burned by supply chain issues in pen tests. One client’s dev team pulled a shady library from npm, and I found a backdoor that could’ve leaked their entire customer database. Today’s npm scare is a reminder to scope third-party risks in every engagement.

Pen Testing Tip: Securing Supply Chains

• Dependency-Check: Use OWASP Dependency-Check to scan for known vulnerabilities in npm packages.
• Shodan for Vendors: Check if third-party vendors expose APIs or servers online. A quick Shodan query can reveal weak links.
• Code Audits: Manually review critical dependencies, especially recent commits from new contributors. Look for base64-encoded payloads or weird imports.

Supply chain attacks thrive on trust. Break that trust with rigorous testing.

Smart Device Hijacking and Scams: The Human Factor

Today’s X posts also flagged smart device hijacking and scams, including virtual kidnapping and DVLA fraud. @th4ts3cur1ty reported attackers exploiting IoT devices and tricking users with social engineering. As a pen tester, I love exploiting human error—it’s often easier than cracking a system. In one gig, I convinced an employee to plug in a “lost” USB drive (my payload, naturally). Game over.

The human element is where most attacks start, whether it’s a smart thermostat exposing a network or a panicked employee falling for a scam. Today’s scams show why pen testers need to think like con artists.

Pen Testing Tip: Targeting Humans

• OSINT with Maltego: Use Maltego to gather employee data for targeted phishing or vishing campaigns.
• SET for Phishing: Craft convincing scam emails with SET, mimicking DVLA or kidnapping lures to test user resilience.
• IoT Scanning: Use Nmap to find exposed IoT devices on client networks. Default creds on a smart camera? Instant win.

Humans are squishy. Train them, test them, and patch their bad habits.

Ethical Hacking in Today’s Chaos

June 16’s events—Chinese APTs, BERT ransomware, AI malware, npm attacks, and scams—are a snapshot of why ethical hacking matters. Every pen test I run is a chance to stop the next PurpleHaze or HijackLoader. The UK’s CBEST program, which uses ethical hackers to test banks, shows how our skills protect critical systems. But with state-sponsored actors and AI in the mix, we’re up against some serious firepower.

That’s why I’m always leveling up, whether it’s mastering a new Burp Suite plugin or diving into Digital Warfare’s IoT security insights. Pen testing isn’t just a job—it’s a mission to keep the internet from imploding.
