Japan Quake Spam (II)

As was predicted by many, email scams soliciting donations for Japan are appearing in user’s inboxes. We took a closer look at one of these messages and identified the following details:

This email was apparently sent from an IP address in Canada via a mail server in Spain. The “From” and “Reply To” fields show a Japanese mail address and are most probably spoofed, while the message body mentions “Sasiki Nakatawo”, a very uncommon, if not totally fictitious name, as the recipient of funds sent by Western Union money transfers. Potential victims are then requested to send their data and Money Transfer Control Number to a mail address in Hong Kong. By the way, the character setting of the mailer used to compose the message was set to “Windows-1251” (Cyrillic).

As we can see, there are a number of different locations around the world linked to this scheme. However, Kaspersky Lab’s mail filtering products put this kind of stuff where it really belongs – the SPAM folder.

Lazarus covets COVID-19-related intelligence

As the COVID-19 crisis grinds on, some threat actors are trying to speed up vaccine development by any means available. We have found evidence that the Lazarus group is going after intelligence that could help these efforts by attacking entities related to COVID-19 research.

Sunburst: connecting the dots in the DNS requests

We matched private and public DNS data for the SUNBURST-malware root C2 domain with the CNAME records, to identify who was targeted for further exploitation. In total, we analyzed 1722 DNS records, leading to 1026 unique target name parts and 964 unique UIDs.

What did DeathStalker hide between two ferns?

While tracking DeathStalker’s Powersing-based activities in May 2020, we detected a previously unknown implant that leveraged DNS over HTTPS as a C2 channel, as well as parts of its delivery chain. We named this new malware “PowerPepper”.
