Check Point Research, the Threat Intelligence arm of Check Point® Software Technologies Ltd., a provider of cyber security solutions globally, has published its latest Global Threat Index for September 2020. Researchers found that an updated version of Valak malware has entered the Index for the first time, ranking as the 9th most prevalent malware in September.
First observed in late 2019, Valak is a sophisticated threat which was previously classified as a malware loader. In recent months, new variants were discovered with significant functional changes which enable Valak to operate as an information-stealer capable of targeting both individuals and enterprises. This new version of Valak is able to steal sensitive information from Microsoft Exchange mail systems, as well as users’ credentials and domain certificates. During September, Valak was spread widely by malspam campaigns containing malicious .doc files.
