2020-03-16 - QUICK POST: MALSPAM KNOWN FOR URSNIF (GOZI/ISFB) SWITCHES TO ICEDID (BOKBOT)

NOTICE:

• The zip archives on this page have been updated, and they now use the new password scheme.  For the new password, see the "about" page of this website.

ASSOCIATED FILES:

• 2020-03-16-IcedID-infection-traffic.pcap.zip   891 kB (890,597 bytes)
• 2020-03-16-IcedID-malware-and-artifacts.zip   223 kB (222,525 bytes)

NOTES:

• This malspam campaign is known for spreading Ursnif using English and other languages.  Here is a relatively recent example.
• However, today instead of Ursnif (or Gozi/IFSB), it pushed IcedID malware.
• Chain of events: malspam --> password-protected zip attachment --> extracted Word doc --> enable macros --> IcedID
