In another display of incompetency, Orange (Romania branch) was hacked again, this time by Rey from the HELLCAT Ransomware group. They were breached alongside another major telecom company from Slovenia, likely using Infostealer credentials which Hudson Rock had prior to the breach.
Previous breaches by the group include Schneider Electric and Telefónica, both of which were carried out using credentials obtained from Infostealer infections of employees—credentials that Hudson Rock had prior to the breach. These breaches too were highly preventable.
For these two new hacks, I assume they also used Infostealer credentials, as both companies had recently infected employees with credentials to sensitive applications such as Jira—similar to what was used in the Schneider Electric and Telefónica breaches.
A large amount of data was stolen, including emails, source code, invoices, and more.
Fun fact: Orange was hacked just a year ago using Infostealer credentials from a compromised employee. We had those credentials prior to that breach as well.
Practice Verified Codes and Commands:
1. Detecting Infostealer Malware on Windows:
Get-Process | Where-Object { $_.ProcessName -match "infostealer" }
2. Checking for Suspicious Processes on Linux:
ps aux | grep -i infostealer
3. Monitoring Network Traffic for Exfiltration:
tcpdump -i eth0 -w capture.pcap
4. Analyzing Captured Network Traffic:
tshark -r capture.pcap -Y "http.request.method == POST"
5. Securing Jira Credentials:
sudo chmod 600 /path/to/jira/credentials
6. Enabling Two-Factor Authentication on Jira:
sudo jira-config.sh --enable-2fa
7. Scanning for Vulnerabilities with Nmap:
nmap -sV --script=vuln target_ip
8. Blocking Suspicious IPs with iptables:
sudo iptables -A INPUT -s suspicious_ip -j DROP
9. Checking for Open Ports:
netstat -tuln
10. Securing SSH Access:
sudo nano /etc/ssh/sshd_config <h1>Change PermitRootLogin to no</h1> <h1>Change PasswordAuthentication to no</h1> sudo systemctl restart sshd
What Undercode Say:
The recent breach of Orange Romania by the HELLCAT Ransomware group underscores the critical importance of robust cybersecurity measures. Infostealer malware continues to be a significant threat, often exploiting compromised credentials to gain unauthorized access to sensitive systems. To mitigate such risks, organizations must implement multi-layered security strategies, including regular vulnerability assessments, stringent access controls, and comprehensive employee training.
In the context of this breach, it is essential to monitor and secure credentials for critical applications like Jira. Regularly updating and patching software, employing intrusion detection systems, and conducting periodic security audits can significantly reduce the attack surface. Additionally, leveraging tools like Nmap for vulnerability scanning and iptables for network security can help in identifying and blocking potential threats.
For Linux systems, commands such as ps aux, tcpdump, and `netstat` are invaluable for monitoring processes, network traffic, and open ports. On Windows, PowerShell scripts can be used to detect and manage suspicious activities. Enabling two-factor authentication and restricting root access on SSH are also crucial steps in securing systems.
In conclusion, the Orange Romania breach serves as a stark reminder of the ever-evolving cyber threat landscape. Organizations must remain vigilant, continuously updating their security protocols and educating their workforce to combat sophisticated cyberattacks effectively. By adopting a proactive approach and utilizing the right tools and commands, businesses can better protect their digital assets and maintain the trust of their stakeholders.
