Marketing, identity theft and malware

Email-aware worms and viruses remain a problem for businesses but are far outnumbered by the huge amounts of spam that attempts to penetrate the enterprise gateway every day.

What does spam do?

Most spam is designed to make money for the spammers. Top of the list is medical-related spam (which claims to assist in sexual performance, weight loss, or human growth hormones). Spam containing adult content and stock-related "pump-and-dump" scams are also prolific.

Other spam contains malware that steals passwords and other confidential information or contains links to bogus websites which phish for bank details or credit card information.

The growing challenge of spam

In response to effective anti-spam measures, cybercriminals are tweaking their campaigns more and more quickly - as frequently as every 30 minutes - to evade spam filters.

They are also using increasingly sneaky techniques. Image spam has no text but has URLs for phishing websites embedded as graphics, making it much harder than text to detect. Voice phishing spam contains no digital threat but convinces people to call bogus phone numbers and verbally give their bank or other financial details.
