Uber has been HACKED By a Teen

Uber says it’s investigating a “cybersecurity incident” and alerted the law-enforcement authorities. The alleged hacker, who claims to be an 18-year-old, says they have administrator access to company tools including Amazon Web Services and Google Cloud Platform. The New York Times reports that the ride-hailing business has taken multiple internal systems, including Slack, offline while it investigates the breach. The alleged breach had reportedly forced Uber to take several internal communications and engineering systems offline.

The hacker’s screenshots appear to indicate full access to many critical Uber IT systems, including the company’s security software and Windows domain. The hacker also gained access to the company’s Amazon Web Services console, VMware ESXi virtual machines, Google Workspace email admin dashboard, and Slack server, to which the hacker posted messages.

How this attack worked initially (According to news and Twitter):

  • The attack initiated with a social engineering technique that compromised an employee’s VPN credentials.
  • The gained credentials allowed the attacker to scan the intranet and gain VPN access to Uber’s internal network.
  • The internal network held PowerShell scripts with the login information for a Thycotic “admin” user (PAM).With this, the “extraction of secrets” for all services began (DUO, AWS, GSuite,etc.)

Investigation:

Uber has obviously taken notice of this, and they are currently looking into the issue.

How the attacker bypassed the MFA?:

For their employees, Uber appears to use push notification MFA (Duo). How might an attacker circumvent MFA?
Push, touch, and mobile MFA are frequently erroneously thought to protect users against social engineering. MiTM attacks typically continue to be a threat even when MFA can stop an attacker who merely has access to the victim’s credentials.

With the use of tools like Evilginx, an attacker can set up a counterfeit domain that delivers the legitimate Uber login page to the victim (an Uber employee). The question is how the attacker will persuade the victim to visit his phishing website.

It was actually quite simple, the attacker continually pushed and denied the victim’s MFA requests to overwhelm him, and then he pretended to be an “IT” team over WhatsApp to convince the victim to visit his created phishing page and enter credentials on the totally fake Uber login page. The attacker obtains the logs and sends the response to his own local server.

It appears that PowerShell scripts were located on a private network share. Using the admin user’s username and password from one of the Powershell scripts, the user was able to extract the secrets for all the services, including AWS, Gsuite, and others.

Once the attacker compromised an employee, they appear to pivot the internal network using the victim’s already-existing VPN connection.:

In this incident, it appears that the attacker discovered an internal network share that held scripts with privileged access, granting them the authority to control. Hackers allege that they have infiltrated the Duo, OneLogin, AWS, and GSuite infrastructures of Uber.

By tricking the victims into accepting a prompt that allowed the attacker to register their own device for MFA, the attacker claims they were able to secure persistent MFA access to their compromised accounts. Below are the screenshots from the Hacker:

The attacker shared several screenshots of Uber’s internal environment, including their Drive VCenter, sales metrics, Slack and even their EDR portal. Right now, the compromised HACKERONE account is the greatest concern for UBER. The attacker has access to all the vulnerabilities that were reported to UBER by different security researchers and given that the average SLA to apply a patch for a vulnerability ranges from one month to even six months, this is a serious concern.

As a preventative measure against these cyberattacks:

  • The Firm should regularly provide the security awareness training to its employees on phishing attacks and campaigns.
  • It is not recommended to utilise a single set of credentials to access all services. Switch to certificate-based authentication.
  • Restricting internal service access to a minimum and only granting the user the necessary access.
  • Shared drives and other internal drives need to be frequently examined for private information (PII) and other sensitive data. The vault should be used to store sensitive data.

Conclusion:

  • In this day and age, all businesses, no matter how big or little, are vulnerable to cyberattacks. As of September 18,2022,Uber Technologies’ net value was $63.02 billion. They were still the target of a cyberattack.
  • Never undervalue the impact that cyberattacks can have on the reputation of your company and brand.
