BofA ‘Online Banking Passcode Reset’ themed emails serve client-side exploits and malware

Cybercriminals are currently mass mailing millions of emails, in an attempt to trick Bank of America customers into clicking on the exploit and malware-serving link found in the spamvertised email. Relying on bogus “Online Banking Passcode Changed” notifications and professionally looking email templates, the campaign is the latest indication of the systematic rotation of impersonated brands in an attempt to cover as many market segments as possible.

More details:

Sample spamvertised and compromised URLs participating in the campaign – hxxp://kuj-pom.pl/wp-content/themes/simplenotes/resetPass.html; hxxp://mastropasticcere.bar.it/wp-content/themes/default/resetPass.html; hxxp://1980.mods.jp/wp-content/plugins/passchanged.html; hxxp://sunsetheroes.com/wp-content/plugins/1/passchanged.html; hxxp://www.jee-choi.com/test/wp-content/plugins/intensedebate/resetPass.html

Client-side exploits serving URL: hxxp://the-mesgate.net/detects/signOn_go.php – 183.81.133.121, AS38442 – Email: counseling72@yahoo.com

Also responding to the same IP are the following malicious domains:
stafffire.net – 183.81.133.121, AS38442
hotsecrete.net – Email: counseling1@yahoo.com
formexiting.net – suspended domain
navisiteseparation.net – suspended domain

Name servers part of the campaign’s infrastructure:
Name Server: NS1.TOPPAUDIO.COM – 91.216.93.61, AS50300 – Email: windowclouse@hotmail.com
Name Server: NS2.TOPPAUDIO.COM – 29.217.45.138 – Email: windowclouse@hotmail.com
Name Server: NS1.TWEET-TOWEL.NET – 208.88.124.81 – Email: worldonaplate@rocketmail.com
Name Server: NS2.TWEET-TOWEL.NET – 5.88.90.51 – Email: worldonaplate@rocketmail.com
Name Server: NS1.ELEPHANT-TRAFFIC.COM – 217.11.251.172
Name Server: NS2.ELEPHANT-TRAFFIC.COM – 217.11.251.171
Name Server: NS3.ELEPHANT-TRAFFIC.COM – 217.31.59.77

We’ve already seen the same email (windowclouse@hotmail.com) used in a previously profiled malicious campaign impersonating Intuit – “‘Intuit Payroll Confirmation inquiry’ themed emails lead to the Black Hole exploit kit“, where the client-side exploit-serving URL (art-london.net) was also registered with the same email.

Related malicious domains responding the these IPs:
change-hot.net
locksmack.net

Money mule recruitment domains using the same IP as a mailserver:
aurafinancialgroup.com
epscareers.com

As you can see, this campaign is great example of the very existence of the cybercrime ecosystem. Not only are they spamvertising millions of exploits and malware serving emails, they’re also multitasking on multiple fronts, as these two domains are recruiting money mules to process fraudulently obtained assets from the affected victims.
