Enterprise Security / Cyber Attack

Cybersecurity experts at Impress IT Solutions are alerting businesses in West Houston to a rising cyber threat known as “device code phishing,” an attack technique recently highlighted by Microsoft. This sophisticated phishing method is being actively exploited by a hacker group identified as Storm-2372, targeting various industries worldwide, including IT services, government agencies, healthcare, and energy sectors.

Since August 2024, this cyber threat has been used to compromise businesses by leveraging deceptive tactics. Attackers use messaging platforms like Microsoft Teams, WhatsApp, and Signal to impersonate trusted contacts or industry figures, luring unsuspecting employees into revealing sensitive information.

How Device Code Phishing Works

Device code phishing is a technique designed to manipulate users into entering authentication codes on legitimate login pages. This allows attackers to hijack authenticated sessions and gain access to business networks.

  1. Attackers send phishing messages masquerading as legitimate Microsoft Teams meeting invitations or business-related requests.
  2. Victims are prompted to authenticate using a seemingly valid device code.
  3. Once the code is entered, hackers intercept authentication tokens, granting them unauthorized access to company accounts.
  4. Attackers leverage these compromised credentials to infiltrate emails, cloud storage, and other business-critical systems.
  5. The threat actors use Microsoft Graph to search through breached accounts, scanning for keywords such as “admin,” “password,” “credentials,” and “gov,” enabling deeper access into organizational data.

Impact on West Houston Businesses

For businesses in West Houston, particularly those in construction, manufacturing, and IT services, a successful device code phishing attack can lead to severe consequences, including:

  • Unauthorized access to sensitive client data
  • Financial fraud and extortion
  • Network disruptions and operational downtime
