REDWOOD CITY, Calif., — Anomali, a leader in threat intelligence, today published its latest cyber threat intelligence research blog. As part of its ongoing Royal Road Weaponizer analysis, the Anomali Threat Research Team confirmed that specific Chinese Advanced Persistent Threats (APTs) are sharing a supply chain for exploits in Microsoft Office products. Key evidence observed confirming this belief includes an observation showing that the threat actors all updated their weaponizers to use a new exploit on or around the same time.
Observations also indicate that the threat actors may have the ability to develop exploits on their own. Evidence observed further shows that after using them, they may be selling them to a wider range of groups, as these are now appearing in commodity-malware campaigns.
“When we began this research, our focus on the malicious RTF weaponizer and groups using them led us to suspect that these APTs, which typically work in silos, were collaborating or sharing the same supply chain. We realized that this is the case after observing that all of the groups updated their weaponizers to use new exploits at almost the same time,” said Ghareeb Saad of the Anomali Threat Research Team. “This observation is significant. It shows that these threat actors have exploit developing capabilities and are operating together. Such a move could help them to become more efficient and effective.”
Detailed findings are revealed in the blog: Multiple Chinese Threat Groups Exploiting CVE-2018-0798 Equation Editor Vulnerability Since Late 2018. It details activities and exploits shared among five Chinese groups: Conimes, KeyBoy, Emissary Panda, Rancor, and Temp.Trident.
