Single group did 66% of world's phishing

A single criminal operation was responsible for two-thirds of all phishing attacks in the second half of 2009 and is responsible for a two-fold increase in the crime, a report published this week said.
The Avalanche gang is believed to have risen out of the ashes of the Rock Phish outfit, which by some estimates was responsible for half the world's phishing attacks before fizzling out in late 2008. Driving the success of both groups is their use of state-of-the-art technology for mass-producing imposter websites and distributing huge amounts of crimeware for automating identity theft.

"Avalanche uses the Rock's techniques but improved upon them, introducing greater volume and sophistication," the report, released by the Anti-Phishing Working Group, stated.

Central to Avalanche's success is its use of fast-flux botnets to host phishing sites. The use of peer-to-peer communications makes it impossible for a single ISP or hosting provider to to pull the plug on the infrastructure. The gang also excels at launching attacks from a relatively small number of domain names that often appear confusingly identical to each other, such as 11f1iili.com and 11t1jtiil.com. Those abilities also fuel the success.
There were 126,697 phishing attacks during the second half of 2009, more than double the number in the first half of the year or from July through December of 2008, the APWG report said. Avalanche, which was first identified in December of 2008, was responsible for 24 percent of phishing attacks in the first half of 2009 and for 66 percent in the second half. From July through the end of the year, Avalanche targeted the more than 40 major financial institutions, online services, and job search providers.
Curiously, Avalanche may turn out to be a victim of its own success.
"During an Avalanche campaign, it was not unusual for the target institutions, the relevant domain name registrar(s), a domain name registry, and other responders and service providers to all be aware of the campaign and working on mitigation at the same time," the report stated. "As a result, Avalanche attacks had a much shorter average uptime than non-Avalanche phishing attacks, and community efforts partially neutralized the advantage of the fast-flux hosting."
White hats briefly shut down the Avalanche infrastructure in mid November, and ever since then phishing attacks generated by the group have dropped precipitously. Last month, the gang launched just 59 attacks, each one with a separate domain.

10 Ways to Spot an E-Mail Scam

The increasing flood of e-mail hitting your inbox can lower the guard of even the most cautious person. In the rush to keep up with important notes, it's easier than ever to fall prey to the scam artists and identity thieves who lurk online.

E-mail scams and phishing attempts evolve constantly, hoping to take advantage of the latest trends and current events. Although the e-mails change, the people behind them inadvertently send up the same warning signs again and again. We dug through mountains of spam to find the most prevailing trends. We've collected some actual scam e-mails and highlighted the warning signs to help you spot a hustle the next time one lands in your inbox.


1. Requests for personal information

No legitimate organization will ask for your social security, bank account or PIN number via e-mail – and none will include a link, sending you to a form to enter it. No matter how authentic these emails may look, ignore 'em.


2. Watch for typos or spelling mistakes

Scam artists are street smart, but many flunked basic grammar (or barely speak English). Look for mistakes like inappropriate hyphens or confusing "your" and "you're." If the note has multiple typos or grammatical errors, odds are it's not legitimate.


3. Clickable Web links in e-mails

Don't trust links to Web sites in e-mails. What might look like a legitimate address is often linked to a third-party site that looks official, but is actually run by thieves and scammers. These are the fast track to identity and financial theft.


4. 'Market research' or surveys that ask you for personal information.

Disguising scam e-mails as marketing is a classic ploy. You'll be asked to fill out a survey or enter a contest – requiring you to give personal information or "log on" to your account. Once you've done so, the scammers can use it themselves.


5. Stock tips from random people or companies

Got a "hot stock tip" via e-mail? It's probably a "pump and dump" scheme. The sender already owns shares – and when you and others act on the "tip," the stock price soars and he sells fast – leaving you with virtually worthless shares.


6. Attachments in e-mails from anyone you don't know

It should be common sense, but just in case, we'll remind you again: Don't open an attachment from someone you don't know – even if it appears to be your bank or credit card company. It's almost always a virus or spyware meant to steal your personal information.


7. Wordless e-mails

Some legitimate looking "e-mails" are actually just images. The danger with these is that clicking anywhere in the body takes you to a suspect Web site – where you may be fooled into entering personal information, or the scammer may slip spyware onto your machine.


8. Outdated information

Some scammers like to pose as technical- or customer support from a company you associate with – but fail to keep up with current events. For example, in the example above, the senders forgot that Earthlink bought Mindspring in 2000.


9. Red-flag phrases

If you see the phrases "verify your account," "you have won the lottery" or "if you don't respond within XX hours, your account will be closed," it's a scam – every time. Hit the delete button and don't look back.


10. Generic greetings

While you can't trust every e-mail that knows your name, you can definitely ignore the ones that start "Dear member" or "Hello friend." If your bank or credit card company is writing you, it knows who you are. So do your friends.
