Valak

aka: Valek

According to PCrisk, Valak is malicious software that downloads JScript files and executes them. What happens next depends on the actions performed by the executed JScript files. It is very likely that cyber criminals behind Valak attempt to use this malware to cause chain infections (i.e., using Valak to distribute other malware).

Research shows that Valak is distributed through spam campaigns, however, in some cases, it infiltrates systems when they are already infected with malicious program such as Ursnif (also known as Gozi).
