North Korean Hackers Use Malicious Zoom Apps to Execute System-Takeover Attacks

Cybersecurity researchers and targeted individuals have reported a highly sophisticated scam orchestrated by suspected North Korean hackers.

This attack, disguised as a legitimate Zoom meeting, leverages advanced social engineering techniques to trick professionals into compromising their systems.

The campaign, which surfaced recently, highlights the growing audacity and technical prowess of state-sponsored threat actors aiming to steal sensitive data and crypto assets from unsuspecting victims.

Sophisticated Social Engineering Tactics Uncovered

The attack begins with a seemingly innocuous outreach on professional networking platforms like LinkedIn.

A fraudulent account, posing as a potential business collaborator, initiates contact under the guise of exploring a company’s services.

In one documented case from June 2025, the scammer, using the alias Valéria Pereira with the email [email protected], engaged the target and swiftly moved the conversation to Telegram for further interaction.

Following this, a meeting was scheduled via the victim’s calendar link, adding an air of legitimacy to the exchange.

However, the trap was set just 20 minutes before the supposed call, when the attacker urged the victim to join a meeting via a malicious link hosted on a deceptive domain, usweb08.us.

This domain, registered on April 17, 2025, through Namecheap under the likely fictitious name Daniel Castagnolii of Hana Network, was crafted to mimic Zoom’s branding and interface with startling precision.

Fake video tiles, chat messages, and simulated participants created an illusion of a genuine meeting environment.

Anatomy of a Deceptive Cyberattack

As the scam unfolded, the victim was prompted to address a fabricated audio connection issue by visiting a counterfeit Zoom help page.

This page instructed the user to execute terminal commands on their system a critical step that, if followed, would likely have granted the attackers remote access to the device.

Experts suspect that such access could facilitate the theft of cryptocurrency wallets, corporate data, or the installation of persistent malware for espionage.

Fortunately, the target in this instance grew suspicious, refused to run the commands, and proposed switching to Google Meet.

The attackers, citing a fabricated “company policy,” resisted the change and soon deleted the Telegram conversation, erasing their digital footprint.

Further investigation into the domain usweb08.us revealed its recent creation and questionable registration details, pointing to a meticulously planned operation.

Such tactics align with known strategies of North Korean hacking groups like Lazarus, notorious for blending technical exploits with psychological manipulation to target high-value individuals and organizations.

The urgency and polished execution of this scam underscore a shift toward more convincing and professionally tailored cyberattacks.

This incident serves as a stark reminder of the importance of cybersecurity vigilance.

According to the Report, Professionals must scrutinize URLs before clicking, avoid executing unverified commands, and remain wary of rushed or unusual requests during online interactions.

As threat actors continue to refine their methods, staying informed and cautious is the first line of defense against such insidious system-takeover attempts.

If something feels off during a digital exchange, pausing to verify the source can prevent catastrophic breaches.

Cybersecurity experts urge individuals and companies to share knowledge of such scams to bolster collective defenses against these evolving threats.
