a brief history of worms

my last post about DTI's website being hacked prompted me to do some research on internet viruses and worms.

according to, the term "worm" originated from a science fiction story called "The Shockwave Rider" written by John Brunner in 1975. the story is about a totalitarian government that controls its citizens through a powerful computer network. a freedom fighter infests this network with a program called a "tapeworm" forcing the government to shut down the network, thereby destroy its base of power.
although worms now are considered malicious, however did you know that worm programs were actually originally designed to facilitate better usage of a network?

in 1971 Bob Thomas developed a program that help notifies air traffic controllers about plane movements called "creeper." the "creeper" travels from screen to screen in a network displaying the message, "i'm creeper! catch me if you can!"

in the early 1980's, John Shock and Jon Hepps of Xerox's Palo Alto Research Center developed 5 worms, each of which were designed to perform helpful tasks around the network. one that stands out was the "vampire" worm which remains idle during the day, but @ night did complex tasks. kewl di ba?

well, as the movie says - "with great powers come great responsibilities." good things when misused becomes harmful as well.

on november 2, 1988, Robert Morris, Jr., a graduate student in Computer Science @ Cornell, wrote an experimental, self-replicating, self-propagating program and injected it into the internet. Morris released it @ MIT and soon spread around the country crashing machines and putting them in 'catatonic' state - as usual it had a bug!

he along with a friend tried to anonymously remedy the situation but was too late. a team of programmers worked non-stop to contain the situation.

Morris later was convicted of violating the computer Fraud and Abuse Act and was sentenced to three years of probation, 400 hours of community service, a fine of $10,050, and the costs of his supervision.

in the recent years the worm have mutated in several ways. and of course, IT PINOYs didn't want to be left behind, do you still remember the "ILOVEYOU" virus which spread throughout the globe in just one day? well that's another blog-worthy story..

the facebook breakup letter

dear facebook,

today marks our 10th year together, i must say it has been a sweet journey. unfortunately, time has come for me to walk away.

i had high hopes for us when we started, especially at the time when my heart still beat for… what was her name again? ahh friendster (may she rest in peace). but you were all smile and poised, a neatly uniformed college girl full of hopes and overflowing with excitement. you had me at one poke!

through you i bravely opened up my thoughts to the world. i was able to connect with old and new friends. you bridged time, the longitudes and the latitudes. i got found and new relatives were discovered. once a year you even make me famous sending out birthday reminders. with you, i was a kid in a playground, swiping up or down till the wee hours, unconditionally tagging anyone and gleefully enjoying your games.

know that i am glad to have witnessed you grow - your fun emojis, crazy virals, and live videos i will sorely miss. oh i always thought it’s cool…

Facebook's Mark Zuckerberg Faces Congress

Facebook CEO, Mark Zuckerberg faced the senate judiciary and commerce committees today, in light of the recent data breach impacting over 87 million of its users.  
on march-21 addressing the cambridge analytica situation, "We have a responsibility to protect your data, and if we can't then we don't deserve to serve you. I've been working to understand exactly what happened and how to make sure this doesn't happen again. The good news is that the most important actions to prevent this from happening again today we have already taken years ago. But we also made mistakes, there's more to do, and we need to step up and do it," mark posted. 

here's a background of events;

as early as 2007 facebook envisioned that apps should be "social" enabling people to log into apps and share who their friends were and some of their information (birthdays, where they live, photos).  in 2013, a cambridge university researcher named aleksandr kogan created a perso…

PINOY OFWs Beware of New E-Mail Scam

an email scam has been recently reported targeting the PINOY Overseas Contract Workers (OFWs). 

the Philippine Overseas Employment Administration (POEA) advised everyone to ignore emails telling them they have qualified and may apply as a nurse or caregiver at the Canadian Virtual Hospice in Winnipeg, Canada.  

the said email further added that applying for the job does not have hidden charges and that the employer will shoulder the airfare, work permit fee, and working visa (sounds interesting huh?). now the catch... the candidate is told to pay at a designated Western Union and/or LBC account, for the coaching and medical exam fees and to reserve a slot at the embassy for the coaching seminar. 

its unnerving how some take advantage of people who are just trying to earn a better and honest living.  please share this, be aware.
