Federal Bureau of Investigation Warns Public of Fraudulent Spam Email

October 14th, 2009 . by DarkFiber Consulting

The Federal Bureau of Investigation (FBI) has released information warning the public about fraudulent email messages purporting to come from the FBI or the Department of Homeland Security. These email messages contain a malicious attachment that claims to provide an intelligence report or bulletin, but in reality attempts to launch malware on the user’s system.

More information regarding these messages can be found in the Federal Bureau of Investigation’s New E-Scams and Warnings web site.

To help protect against this type of attack, DarkFiber Consulting recommends that users avoid opening attachments contained in unsolicited email messages. Additional tips regarding email attachments can be found in the DarkFiber Consulting Cyber Security Tip – Using Caution with Email Attachments.

Fake Antivirus Software Circulating

September 16th, 2008 . by DarkFiber Consulting

DarkFiber Consulting is aware of public reports indicating an increase in the instances of fake antivirus software circulating. These software applications are malicious code, not legitimate antivirus applications. These instances of malicious code are noted as being distributed through spam email messages containing malicious links, instant messages containing malicious links, private messages on social networking sites, infection from other malware, and from visiting compromised websites.

Quite often, this malware attempts to convince users that there is something wrong with their systems. This leads to an attempt persuade the users into purchasing an illegitimate antivirus application. If the user purchases the bogus software, the attacker may be able to obtain personal and credit card information for use in additional scams and fraudulent activity.

DarkFiber Consulting encourages users to perform the following preventative measures to help mitigate the risks:

  • Install legitimate antivirus software from a trusted vendor, and keep its virus signature files up-to-date.
  • Do not follow unsolicited web links found in email messages or instant messages.
  • Use caution when visiting untrusted websites.
  • Do not install untrusted software.
