Uncovering the Exploitation of Output Messenger Vulnerabilities by Turkish Hackers on Kurdish Servers: An In-depth Look at Hidden Golang Backdoors
people.
It’s noted that Golang-based backdoors were discovered in connection to this attack.”
Zero-Day Vulnerability in Output Messenger
The vulnerabilities in question relates to the Indian-built enterprise communication platform, Output Messenger.
This tool, widely used by hundreds of businesses worldwide is not publicly believed to be the focus for such cyber attacks, which further indicates the sophistication of the infiltrators.
The zero-day exploit effectiveness comes from how the bug allows arbitrary files to be uploaded to, and then executed on, the target’s server.
Microsoft Threat Intelligence team discovered this afore-mentioned flaw, and urgently advised users to update their version of the software as soon as the fix is available. “It appears the attacker targeted some specific organizations and, had data exfiltration been successful, would have been able to use it for further exploits,” said the Microsoft team.
Golang-Developed Backdoors
The Backdoor is a utility built with Google’s Golang language and dubbed ‘GoCrackDoor’.
This allows Türkiye hackers a hidden, perpetual entry into Kurdish servers.
Coupled with the Output Messenger vulnerability, a successful attack would allow the extraction of sensitive data from targeted servers in Iraq, predominantly Kurdish businesses and organizations.
Defensive Measures
As Golang-related backdoors and targeted attacks on Output Messenger continue to evolve in their sophistication and danger levels, users, especially within Iraq, are advised to take precautionary measures:
- Consistent updating of the Output Messenger application, specifically ensuring versions, which have patched the identified zero-day vulnerability, are installed.
- Execution of rigorous, regular checks for “GoCrackDoor” backdoor across servers and networks.
- Adoption of a cyber-threat intelligence platform to monitor cyber threats and malware campaigns actively.
- Investment in cybersecurity awareness to understand the modus operandi of the Türkiye hackers, along with ways to spot potential attacks.
All of these measures lend to the effort of creating a resilient security posture that can deflect such targeted cyber attacks.
