APT-C-35 (also known as “Donot APT Group”) is a cyber espionage group that has been active since at least 2013. The group is known for conducting cyber espionage and intellectual property theft, targeting government and military organizations, as well as companies in the aerospace, defense, and high-tech industries. Their activities have been observed in several countries, including the United States, Europe, and Asia.
They previously targeted Pakistani users with android malware named (StealJob) which was used to target Pakistani android mobile users by Phishing under the name of “Kashmiri Voice”. The attackers hunt for confidential information and intellectual property. The hackers’ targets include countries in South Asia, in particular, the state sector of Pakistan. Also, in July 2022, the threat actor of this APT group used Comodo’s certificate to sign its spyware. The group is known for using a variety of tactics, techniques, and procedures (TTPs) in their attacks, which include the use of spear-phishing emails, malware, and custom-developed tools. Donot APT group is known to be a well-funded and well-resourced group, with a high level of technical skill. They are also known to use techniques to evade detection, such as using encryption and fileless malware.
Previously, the DoNot APT group has targeted individuals in South Asia using Android malware. The group seems to be using third-party file-sharing websites, as well as potentially their own file-sharing online platform, as a delivery mechanism for their malware.
In another campaign, the group was observed using a lure related to CVE-2023-2033 to entice their victims into downloading a malicious file disguised as an updated version of Google Chrome.
It is important for organizations to be aware of the threat posed by Donot APT group and to take steps to protect themselves from their attacks. This includes implementing security best practices, such as regular software updates and patching, and providing employee training on how to spot and avoid phishing emails. Additionally, organizations should also consider implementing security tools such as intrusion detection and prevention systems (IDPS), endpoint protection platforms (EPP), and advanced threat intelligence (ATI) to detect and respond to Donot APT group’s activities.
