A new malvertising campaign is targeting small and medium-sized businesses (SMBs) with the Vidar Infostealer malware. Attackers are using fake ads for cracked or pirated software to lure victims into downloading the malware, which not only steals sensitive data but also uses the infected machines for cryptomining. This dual-purpose attack poses significant risks to SMBs, as it can lead to data breaches and financial losses. Companies should be wary of downloading software from unverified sources and ensure their cybersecurity measures are up to date. The incident underscores the ongoing threat posed by financially motivated cybercriminals exploiting the desire for free software.
