Noticing more SPAM lately? It's not just you
- A spam increase of 150% in February compared to January
- A spam increase of 210% March (to date) compared to January
Yahoo spam is not really new since Yahoo has been the major source of "freemail" spam for quite a while now. But now it looks like spammers are really starting to take advantage of Yahoo's failure to crack down on account hacking and spammer owned accounts.
Spammers seem to be having a lot more success hacking Yahoo accounts and spamming their address books. These spam messages seem to come from an email address that you are familiar with (but not necessarily from Yahoo) and contain little or no text and a URL. Although the address may not be from Yahoo, the sending server is a Yahoo server,
These spams are more difficult to properly identify since:
- They somewhat resemble real emails
- They contain few, if any, obvious "spammy" words
- They are DKIM signed by Yahoo as vaild emails
- They use a multitude of shortened URLs that point to a spam payload
- They appear to be lower volume spam runs that take a while to hit the URI DNS BLACKLISTS
- Keep antispam appliance subscriptions active,
- Update the appliances where necessary,
- Exercise caution with suspicious, unsolicited, unexpected, or out-of-character emails.
