🔹 Fake Zoom meeting invites and update links deceive Web3 teams

🔹 New NimDoor malware infiltrates macOS with advanced evasion techniques

🔹 Attackers steal browser data, passwords, and Telegram chats

Web3 and Crypto Companies Under Siege by NimDoor Malware
Security experts at SentinelLabs have uncovered a sophisticated malware campaign targeting Web3 startups and cryptocurrency firms. The attacks, linked to North Korean groups, use a combination of social engineering and technical stealth to deploy NimDoor malware, written in the rarely used Nim programming language to bypass antivirus detection.

The Setup: Fake Zoom Meetings Through Telegram
Hackers initiate contact via Telegram, posing as known contacts. They invite victims to schedule meetings via Calendly, then send them links to what appear to be Zoom software updates. These links lead to fake domains like support.us05web-zoom.cloud, mimicking Zoom's legitimate URLs and hosting malicious installation files.
These files contain thousands of lines of whitespace, making them appear "legitimately large." Hidden within are only three crucial lines of code, which download and execute the real attack payload.

NimDoor Malware: Spyware Specifically Targeting macOS
Once executed, the NimDoor malware operates in two main phases:
🔹 Data extraction – stealing saved passwords, browsing histories, and login credentials from popular browsers like Chrome, Firefox, Brave, Edge, and Arc.

🔹 System persistence – maintaining long-term access through stealth background processes and disguised system files.
A key component specifically targets Telegram, stealing encrypted chat databases and decryption keys, giving attackers access to private conversations offline.

Built to Survive: Evasion and Reinstallation Techniques
NimDoor employs a range of advanced persistence mechanisms:
🔹 Automatically reinstalls itself if users try to terminate or delete it

🔹 Creates hidden files and folders that look like legitimate macOS system components

🔹 Connects to the attacker’s server every 30 seconds for instructions, disguised as normal internet traffic

🔹 Delays execution for 10 minutes to avoid early detection by security software

Difficult to Remove Without Professional Tools
Because of these techniques, NimDoor is extremely hard to remove with standard tools. Specialized security software or professional intervention is often required to clean infected systems completely.

Conclusion: Modern Cyberattacks Now Look Like Calendar Invites
Attacks like NimDoor prove how cleverly North Korean groups mimic daily workflows to penetrate even cautious targets. Fake Zoom links and innocent-looking updates can lead to full system compromise.
Users should never download updates from unofficial sources, always verify domain names, and stay vigilant against unexpected software prompts or invitations.

North Korean hacking groups have once again demonstrated how dangerously sophisticated they can be. This time, they’ve set their sights on crypto developers — posing as legitimate U.S.-based companies with one goal: to infect victims’ systems with malware.

🎭 Two Fake Companies. One Malicious Scheme.
Cybersecurity firm Silent Push has revealed that North Korean hackers created two LLCs — Blocknovas LLC in New Mexico and Softglide LLC in New York — pretending to be recruiters in the crypto industry. These companies sent “job offers” that contained malicious code. The notorious Lazarus Group, linked to North Korea’s intelligence services, is believed to be behind the operation.
A third entity, Angeloper Agency, showed the same digital fingerprint, though it wasn’t officially registered.

🧠 Malware That Steals Crypto Wallets
Once unsuspecting developers opened the infected files, the malware began harvesting login credentials, wallet keys, and other sensitive data. According to Silent Push’s report, multiple victims have already been identified — most linked to the Blocknovas domain, which was by far the most active.
The FBI has seized the domain and issued a warning that similar aliases may reappear soon.

💸 Covert Funding for North Korea’s Missile Program
According to U.S. officials, the ultimate goal of the scheme is simple: generate hard currency to fund North Korea’s nuclear weapons program. Intelligence sources say Pyongyang has been deploying thousands of IT operatives abroad to illegally raise funds through fraudulent schemes.
This case is especially troubling because it shows that North Korean hackers managed to set up legal companies inside the United States, a rare and alarming development.

🔐 Three Malware Families, One Lazarus Signature
Analysts found that the job files contained at least three known malware families, capable of opening backdoors, downloading additional malicious payloads, and stealing sensitive information. These tactics align closely with past attacks by the Lazarus Group.

⚠️ FBI Warning: Be Cautious of "Too Good to Be True" Job Offers
Federal agents emphasize that this case is a chilling reminder of how North Korea continues to evolve its cyber threats. Tech and cybersecurity professionals should thoroughly vet unsolicited job offers, especially those from unfamiliar companies. Developers infected by these schemes could lose cryptocurrency or unknowingly grant hackers access to larger systems and exchanges.

North Korean Hackers Orchestrate Sophisticated Attack
A recent postmortem report reveals that North Korea-backed hackers, identified as UNC4736 (also known as Citrine Sleet), exploited Radiant Capital in a $50 million attack. The operation involved advanced social engineering tactics, with the attackers impersonating a "trusted former contractor" and distributing malware via a zipped PDF file.
Phishing Through Fake Domains and Data Manipulation
The hackers created a fake domain mimicking a legitimate Radiant Capital contractor and reached out to the Radiant team through Telegram. They requested feedback on an alleged smart contract audit project. However, the shared file concealed INLETDRIFT malware, which created macOS backdoors, granting the hackers access to hardware wallets of at least three Radiant developers.
Manipulated Transactions and Compromised Security
During the attack on October 16, the malware tampered with the Safe{Wallet} interface (formerly Gnosis Safe), displaying legitimate transaction data to developers while executing malicious transactions in the background. Despite adhering to stringent security protocols like Tenderly simulations and Standard Operating Procedures (SOP), the attackers successfully compromised multiple developer devices.
UNC4736’s Links to North Korea
According to cybersecurity firm Mandiant, UNC4736 is connected to North Korea's General Reconnaissance Bureau. This group is notorious for targeting cryptocurrency companies and financial institutions globally.
North Korean Hackers Fund Nuclear Programs
The Federal Bureau of Investigation (FBI) has previously warned about North Korean hackers’ sophisticated tactics, including targeting cryptocurrency exchanges and prominent firms. Research indicates that these state-backed groups have stolen approximately $3 billion from the cryptocurrency sector since 2017. The stolen funds are reportedly used to finance North Korea's nuclear weapons program.
A Concerning Trend in Cybersecurity
This case highlights the increasing sophistication of cyberattacks, as hackers deploy social engineering and advanced tools to target cryptocurrency firms. Radiant Capital fell victim to a meticulously planned operation, underscoring the urgent need for enhanced security measures within the crypto industry.

💣 New Malware Targets Blockchain Workers — Fake Jobs, Real Threats! 🧠🔐

North Korean hackers are at it again — this time with a sneaky new trick targeting professionals in the crypto industry! 🇰🇵💻 A hacking group known as “Famous Chollima” (aka “Wagemole”) has been using fake job offers to lure crypto experts into downloading a nasty piece of malware called PylangGhost. According to Cisco Talos, this malware is designed to remotely control your computer and steal passwords from crypto wallets and browser extensions like MetaMask, 1Password, and more. 😨🔑
These cybercriminals are impersonating major companies like Coinbase and Uniswap by setting up fake websites and posing as recruiters. Once victims are hooked, they’re guided through a bogus interview process and tricked into running malicious code on their system — all under the pretense of installing a “video driver.” Once the malware is in, it grabs login details, takes screenshots, steals data, and keeps the door open for further attacks. 📷📂🕵️
This isn’t the first time North Korean hackers have pulled this kind of stunt. Similar scams were seen in April, where fake recruitment tests were used to hack developers in the crypto space. As crypto adoption grows, so does the interest from cybercriminals. So, if you're job-hunting in the blockchain world, double-check those offers and never run unknown code — your crypto stash could depend on it! 🔒🛡️
