| 500 | 7 | 3 | 27 | 16 | 46 |
The fourth week of March 2022 witnessed the discovery of 500 vulnerabilities out of which 7 gained the attention of Threat Actors and security researchers worldwide. Among these 10, there were 3 awaiting analysis and 2 were not present in the NVD at all. Hive Pro Threat Research Team has curated a list of 7 CVEs that require immediate action.
Furthermore, we also observed three threat actor groups being highly active in the last week. A financially motivated threat actor called TA551 primarily targeted English, German, Italian, and Japanese speakers through IcedID an email-based malware. A new variant of the famous PlugX malware called Talisman has been discovered to be used by Chinese state-sponsored threat actor RedFoxtrot. These attacks were staged on telecommunication and defense sectors in South Asian countries to protect the Belt and Road initiative. Deep Panda aka APT 19, a Chinese APT group, exploited the infamous Log4Shell vulnerability in VMware Horizon servers to stage attack on various sectors across the globe. Common TTPs which could potentially be exploited by these threat actors or CVEs can be found in the detailed section below.
