MessageLabs Warns: Two New Strains of Trojan Downloader on the Loose

  • 08 July, 2005 10:24

<p>MessageLabs, the leading provider of email security and management services to businesses, is warning computer users to be on guard against two new Trojan downloaders being spammed out - the first one was intercepted at 10:18 EST yesterday, while the second at 11:06 EST. MessageLabs has since intercepted over 54,000 copies of email-borne malware.</p>
<p>Both downloaders have the same email characteristics. The email purports to be a spam report spoofed from an admin@ address requesting users to take action in order to prevent their email account from being shut down. Recipients are tricked into opening a malicious file, which once activated drops an executable file onto infected machines opening up the machines to hackers.</p>
<p>Email characteristics:</p>
<p>SUBJECT: Spam Report</p>
<p>ATTACHMENT: report.log.exe</p>
<p>BODY:</p>
<p>Dear <email address=""> user,</email></p>
<p>Your e-mail account was used to send a huge amount of unsolicited spam messages during the recent week. If you could please take 5-10 minutes out of your online experience and confirm the attached document so you will not run into any future problems with the online service.</p>
<p>If you choose to ignore our request, you leave us no choice but to cancel your membership.</p>
<p>Virtually yours,</p>
<p>Network Administrator Team</p>
