Where the heck is all this spam coming from?

Filter Fish

The growth of the spam problem in 2002 has been exponential,

writes Kevin Murphy

. Companies that sell spam filtering software say currently the percentage of email that is spam could be 20%, 33%, or even up to 50%, compared to less than 10% a year ago.

While the rise in spam is easy to notice, it is hard to quantify. Spam is by definition "unsolicited commercial email", and often spamees cannot remember signing up to have their email addresses added to lists, or were not aware they were doing so.

BrightMail Inc, the market leader in anti-spam services, says emails sent to its honey-pot email addresses are by definition unsolicited, and that it has seen spam on its customers' networks increase from 8% of mail to 41% of mail in the last 14 months.

Wasting time deleting UCE can be a productivity concern for enterprises. A survey by SurfControl Plc said 25% of enterprise email is spam and that each message costs up to a dollar. CloudMark Inc said 10 spams per day could cost a company $86 per employee per year.

Even if getting spam was free, there's a general consensus it's still annoying enough to want to filter. But why has it become so much of a problem this year? We asked executives from companies that provide anti-spam software and services to explain.

"Now anyone can do it," said Pavni Divanji, CEO of MailFrontier Inc. "The process is so streamlined. You can buy a CD of email addresses, buy mailing software, find an open relay and start doing it. People think it's easy and that they can make a few dollars off it."

The economics of spam are attractive for both the spammers and the companies that pay them to spam, particularly given the macro economy in the US. Email marketing has low response rates, typically less than half a percent, but is very, very cheap.

Growing numbers of e-businesses can't blow $50m of IPO money on TV and direct mail campaigns any more, and all the people they laid off into a depressed job market are looking for new sources of income.

Enrique Salem, CEO of BrightMail, said he talked to a spammer last week who was paid $1,500 to send one million spams. Even with a response rate of just one tenth of a percent, that's 1,000 likely customers reached for $1.50 a head. For the spammer, the cost was negligible.

"A lot of the Chinese, Korean and Latin American spam originates in the US ... People are looking at alternate ways to make money. It's a way to augment their income," said Salem. "Companies are looking at alternative ways to market and reach customers."

It's also exceptionally easy to get started as a spammer. CDs of 150 million email addresses can be bought for as little as $100 online. Web sites maintain lists of open email relays, many in Asia, which can be used to push mail through.

"The social stigma has gone," said MailFrontier's Divanji. "People don't think twice about doing it."

This point is debatable. While spammers think as long as no laws are broken they are not doing anything wrong, recent published interviews with spammers tell stories of harassment from irate spamees, both online and off.

But, just as finding people who respond to spam is a numbers game, finding people who have no ethical qualms with eating the bandwidth of millions of people and giving them headaches every morning should be easy.

"If this trend continues unchecked, it's going to make email unusable," said Salem.

  • GPL legal battle: Vizio told by judge it will have to answer breach-of-contract claims
    Fine-print crucially deemed contractual agreement as well as copyright license in smartTV source-code case

    The Software Freedom Conservancy (SFC) has won a significant legal victory in its ongoing effort to force Vizio to publish the source code of its SmartCast TV software, which is said to contain GPLv2 and LGPLv2.1 copyleft-licensed components.

    SFC sued Vizio, claiming it was in breach of contract by failing to obey the terms of the GPLv2 and LGPLv2.1 licenses that require source code to be made public when certain conditions are met, and sought declaratory relief on behalf of Vizio TV owners. SFC wanted its breach-of-contract arguments to be heard by the Orange County Superior Court in California, though Vizio kicked the matter up to the district court level in central California where it hoped to avoid the contract issue and defend its corner using just federal copyright law.

    On Friday, Federal District Judge Josephine Staton sided with SFC and granted its motion to send its lawsuit back to superior court. To do so, Judge Staton had to decide whether or not the federal Copyright Act preempted the SFC's breach-of-contract allegations; in the end, she decided it didn't.

  • US brings first-of-its-kind criminal charges of Bitcoin-based sanctions-busting
    Citizen allegedly moved $10m-plus in BTC into banned nation

    US prosecutors have accused an American citizen of illegally funneling more than $10 million in Bitcoin into an economically sanctioned country.

    It's said the resulting criminal charges of sanctions busting through the use of cryptocurrency are the first of their kind to be brought in the US.

    Under the United States' International Emergency Economic Powers Act (IEEA), it is illegal for a citizen or institution within the US to transfer funds, directly or indirectly, to a sanctioned country, such as Iran, Cuba, North Korea, or Russia. If there is evidence the IEEA was willfully violated, a criminal case should follow. If an individual or financial exchange was unwittingly involved in evading sanctions, they may be subject to civil action.

  • Meta hires network chip guru from Intel: What does this mean for future silicon?
    Why be a customer when you can develop your own custom semiconductors

    Analysis Here's something that should raise eyebrows in the datacenter world: Facebook parent company Meta has hired a veteran networking chip engineer from Intel to lead silicon design efforts in the internet giant's infrastructure hardware engineering group.

    Jon Dama started as director of silicon in May for Meta's infrastructure hardware group, a role that has him "responsible for several design teams innovating the datacenter for scale," according to his LinkedIn profile. In a blurb, Dama indicated that a team is already in place at Meta, and he hopes to "scale the next several doublings of data processing" with them.

    Though we couldn't confirm it, we think it's likely that Dama is reporting to Alexis Bjorlin, Meta's vice president of infrastructure hardware who previously worked with Dama when she was general manager of Intel's Connectivity group before serving a two-year stint at Broadcom.

  • Lithium production needs investment to keep pace with battery demand
    Report says $42b will need to be poured into industry over next decade

    Growing demand for lithium for batteries means the sector will need $42 billion of investment to meet the anticipated level of orders by the end of the decade, according to a report.

    Lithium is used in batteries that power smartphones and laptops, but there is also rising use in electric vehicles which is putting additional pressure on supplies.

    The report, Benchmark Mineral Intelligence, predicts that demand will reach 2.4 million tons of lithium carbonate equivalent by 2030, roughly four times the 600,000 tons of lithium forecast to be produced this year.

  • Cars in driver-assist mode hit a third of cyclists, all oncoming cars in tests
    Still think we're ready for that autonomous future?

    Autonomous cars may be further away than believed. Testing of three leading systems found they hit a third of cyclists, and failed to avoid any oncoming cars.

    The tests [PDF] performed by the American Automobile Association (AAA) looked at three vehicles: a 2021 Hyundai Santa Fe with Highway Driving Assist; a 2021 Subaru Forester with EyeSight; and a 2020 Tesla Model 3 with Autopilot.

    According to the AAA, all three systems represent the second of five autonomous driving levels, which require drivers to maintain alertness at all times to seize control from the computer when needed. There are no semi-autonomous cars generally available to the public that are able to operate above level two.
