Researchers have spotted the Platinum group targeting organizations in the APAC region with a new Titanium backdoor.

In its analysis, Kaspersky Lab observed the Platinum group using this latest campaign to go after targets located in South and Southeast Asia. The campaign began by using an exploit that was capable of executing code as a SYSTEM user. It then leveraged shellcode to install a downloader, a resource that pulled down a password-encrypted SFX archive. This asset installed a Windows task to establish persistence on the infected computer. With that step complete, the campaign moved on to a Trojan backdoor installer that used an installer script and a COM object DLL to eventually load Titanium, the backdoor payload.

Kaspersky Lab found that this campaign used both encryption and fileless techniques to evade detection. The security firm also noted that each step mimicked the activity of known software, including security tools, as a means of further throwing researchers off the campaign’s trail.

A Look Back at Recent Platinum Group Activity

Titanium marks the latest innovation of the ever-evolving Platinum group. Back in June 2017, the Microsoft Defender ATP Research Team observed the group’s file-transfer tool relying on the Intel Active Management Technology (AMT) Serial-over-LAN (SOL) channel for communication, a technique that helped Platinum’s attacks avoid detection by firewalls and network monitoring tools. In June of this year, Kaspersky Lab spotted a new attack for which Platinum had modified its malicious utility and incorporated new evasion tactics.

How to Defend Your Network Against Evasive Attacks

Security professionals can help defend their organizations against evasive campaigns such as those launched by the Platinum group by properly configuring their security information and event management (SIEM) solutions and creating rules to alert the team in the event that a log source stops reporting to their SIEM tool. Companies should also create a data-centric risk management program to help identify and create risk profiles for their sensitive data and thereby better protect the network against all types of attack campaigns.

Who Carries the Weight of a Cyberattack?

Almost immediately after a company discovers a data breach, the finger-pointing begins. Who is to blame? Most often, it is the chief information security officer (CISO) or chief security officer (CSO) because protecting the network infrastructure is their job. Heck, it is even in their job title: they are the security officer. Security is their responsibility. But is that fair – or even right? After all, the most common sources of data breaches and other cyber incidents are situations caused…

Transitioning to Quantum-Safe Encryption

With their vast increase in computing power, quantum computers promise to revolutionize many fields. Artificial intelligence, medicine and space exploration all benefit from this technological leap — but that power is also a double-edged sword. The risk is that threat actors could abuse quantum computers to break the key cryptographic algorithms we depend upon for the safety of our digital world. This poses a threat to a wide range of critical areas. Fortunately, alternate cryptographic algorithms that are safe against…

Abuse of Privilege Enabled Long-Term DIB Organization Hack

From November 2021 through January 2022, the Cybersecurity and Infrastructure Security Agency (CISA) responded to an advanced cyberattack on a Defense Industrial Base (DIB) organization’s enterprise network. During that time frame, advanced persistent threat (APT) adversaries used an open-source toolkit called Impacket to breach the environment and further penetrate the organization’s network. Even worse, CISA reported that multiple APT groups may have hacked into the organization’s network. Data breaches such as these are almost always the result of compromised endpoints…

How Do You Plan to Celebrate National Computer Security Day?

In October 2022, the world marked the 19th Cybersecurity Awareness Month. October might be over, but employers can still talk about awareness of digital threats. We all have another chance before then: National Computer Security Day. The History of National Computer Security Day The origins of National Computer Security Day trace back to 1988 and the Washington, D.C. chapter of the Association for Computing Machinery’s Special Interest Group on Security, Audit and Control. As noted by National Today, those in…
