Tips for a Virus Attack
Call a PC guru and don't shut off your PC which could trigger the infection. Disconnect your online connection. Back up any new data, it might be your only chance. Try to clean it later. Use another PC to learn about the virus. Use anti-virus software to scan and clean. If not treatable, delete the file. Brief your anti-virus software vendor, in case it's an new virus.

Surveillance in Everyday Life
“Surveillance is not inherently good or bad.” Here are five issues about surveillance posed by Eugene Volokh, Professor of Law at UCLA, and author of “The First Amendment” In any given surveillance situation, one has first has to determine: * What concrete security benefits will the proposal likely provide? * Exactly how might it be abused? * Might it decrease the risk of policed abuse rather than increase it? * What control mechanisms can be set up to help diminish the risk of abuse? * What other surveillance is this proposal likely to lead to? “Such analysis suggests that traffic cameras are a good idea at least as an experiment. Cameras at public places from ATM machines to convenience stores are probably worth trying.” Each situation needs to be evaluated independently to determine whether Breathing Space is curtailed or enhanced.

Mega-Spam: No Breathing Space
The website ThisIsLondon.co.uk reports that “image spam” could bring the internet to a standstill. “At first, they seem like your average junk email, containing share tips or an advertisement for Viagra, along with a small, slightly garbled picture.But this, experts say, is the spam that could bring the internet to a virtual standstill this year.” “To bypass anti-spam software, the emails use an image instead of text. In the past six months, this image spam has seen a massive increase and now represents 35 per cent of all junk email, according to security software firm F-Secure and image spam is taking up 70 per cent of the bandwidth bulge. The emails, generally containing stock tips, come from gangs and even bored teenagers in the United States and Russia trying to inflate prices in a swindle called ‘pump-and-dump’. They promise that a cheap, usually American, stock will take off. The perpetrator then dumps his stock as buyers leap in before it collapses.” “Dmitri Allperovitch of computer security company CipherTrust said: ‘They're niche companies with no profit and no products, so when you see a spike from almost no trades to two or three million when the spam is sent out, you know there were a lot of people who fell for it.’” Is your PC a slave unit to such schemes? Are you unwittingly passing bogus information to millions of other people?

Stuffing Our in Bins
All that spam you’re getting? You are not alone. A Reuters report out of London says that “criminal gangs using hijacked computers are behind a surge in unwanted e-mails peddling sex, drugs and stock tips.” According to Postini, a U.S. email security company spam messages have tripled since June and now account for nearly 90% of the e-mails sent worldwide. "E-mail systems are overloaded or melting down trying to keep up with all the spam," said Dan Druker, a vice president at Postini. The Reuters report observes that “as Christmas approaches, the daily trawl through in-boxes clogged with offers of fake Viagra, loans and sex aids is tipped to take even longer.” Postini has detected a staggering 7 billion spam e-mails worldwide in November compared to 2.5 billion in June. According to Spamhaus, an agency that tracks the problem, “About 200 illegal gangs are behind 80 percent of unwanted e-mails. Reuters: Experts blame the rise in spam on computer programs that hijack millions of home computers to send e-mails. These "zombie networks", also called "botnets", can link 100,000 home computers without their owners' knowledge. They are leased to gangs who use their huge "free" computing power to send millions of e-mails with relative anonymity. Labels: email, gangs, internet, networks, privacy, security, spam, work

An Assault on Breathing Space
A study conducted by Commtouch indicates that most spam originates from websites hosted in countries outside the U.S. Pharmaceutical drugs are most advertised, with Viagra the leading the way. The recipients of these largely unwanted messages are nearly all in the U.S. Meanwhile, despite filters and spaminators, the pace of spam is accelerating . The aggregate number of unique spam outbreaks per day has been rising for for more than five years. Labels: email, filter, internet, privacy, security, spam

Too Much Email of the Wrong Kind
50 billion e-mail messages worldwide are sent each day, equal to seven messages for everyone on the planet, although the vast majority of people are not online. In 2001, e-mail traffic was less than 12 billion. Of the 50 billion messages sent daily, more than 88% cent of e-mails are spam including about 1 per cent which are virus-infected. So that means at least 44 billion spam messages are sent each day, 365 days a year, and each day 4.4 billion e-mail messages contain viruses. Has junk email become an issue for you? It’s time to arm yourself to the teeth with with spam protection, virus protection, and a private email account. Labels: email, internet, junk, privacy, security, spam, virus

Long Term Job Security
Are you concerned about long term job security? Ever feel like you lack the time and energy to compete? There are many things you can do that don't take too much time and help you to secure and enhance your position: * Take a few minutes to actually read your organization's annual and quarterly reports, bulletins, press releases, and memos. Read between the lines to determine real needs and what you can do to make a positive difference. * Look for small tasks that others pass over. Your willingness to help out in little ways, can payoff in big ways. * If you're good at writing persuasive sales letters or conducting an effective meeting, volunteer for assignments where you can display your talents and play to your strengths. * Become the resident 'expert' in what the competition is doing, and thus automatically become more valuable to your own organization. Regardless of where you work, there are always ways to demonstrate to others within the organization, the supreme advantage of retaining your services.
