Attackers are putting considerable skill and effort into penetrating industrial companies in multiple countries, with hacks that use multiple evasion mechanisms, an innovative encryption scheme, and exploits that are customized for each target with pinpoint accuracy.
The attacks begin with emails that are customized for each target, a researcher at security firm Kaspersky Lab reported this week. For the exploit to trigger, the language in the email must match the localization of the target’s operating system. For example, in the case of an attack on a Japanese company, the text of the email and an attached Microsoft Office document containing a malicious macro had to be written in Japanese. Also required: an encrypted malware module could be decrypted only when the OS had a Japanese localization as well.
