RSS, blogs and security

Written by Saran on August 7, 2010

Blogs are popularly being read on RSS aggregators these days. That or via Atom feeds and recently, it has been said that attackers could use Javascript to take advantage of this. According to an article on USA Today, this could be any kind of information as long as it is in this format. In the said article, you could also find out the list of vulnerable readers: Bloglines, RSS Reader, RSS Owl, Feed Demon, and Sharp Reader.

This kind of news is actually not so new. Mark Pilgrim was one of the bloggers who has written about this before. He even set up an experiment of sorts, wherein subscribers to his blog feed saw a screen full of platypi. He has mentioned in his blog entry that the difficulty with RSS is that there is a lot of arbitrary HTML and it could include Javascript — it could be malicious Javascript as designed by some attackers. Mark Pilgrim even listen down the elements that should be stripped off by RSS readers, just to be safe:
script tags, embed tags, object tags, frameset tags, iframe tags, meta tags, link tags, style tags, style attributes from every tag.

If you are always subscribing to different blogs, forums and mailing lists through RSS, you should be careful about it. If there are comments RSS, you could also take precautionary measures by not subscribing to it. It is possible to get attacked through the RSS of comments. Aside from that, if you have set up your own personal aggregator, make sure that you have a ’smart’ aggregator which strips off the said tags. If you have an aggregator on your computer, check if it is vulnerable. Maybe you could install something else that isn’t prone to attacks via RSS. It is better to be secure after all.

Putting Up Fences from Internet Spyware and Trojans

Written by Saran on July 27, 2010

Harmful objects can be obtained from the web. We are all aware that Malware and Trojans are rampant objects that have been wandering of anywhere on the Internet, especially websites that are often visited by people for reference and information. Such sites would get hijacked and also contaminate visiting users as well, something that can be done through Internet cookies stored on the web folder in the machines.

Picket Fences on the Web

While developers and security administrators have religiously searched for ways to find such solutions, the ever changing development of new threats coming from the Internet has been far from over. To date, even the well-protected workstations can still be penetrated by objects that are not immediately visible.

Internet fences in the form of firewalls and software protection templates have tried to stop such intrusions but need to be updated frequently to answer the related threats. Without such temporary fences that are up, workstations are sitting ducks waiting to be shot, and if web administrators are not up to date with the new threats, the fences used are good as gone once they occur.

Precautions with Bluetooth Connections

Written by Saran on July 13, 2010

Among the features that most mobile phones have today is that of features that include the Bluetooth and Infrared connectivity as a means of wireless connections. While such advancements has made it easier for people to transfer files such as images and sounds from one phone to another, it also becomes a loophole to allow viruses to infect the operating system of mobile phones today.

Cabir Bluetooth Precaution

Worms such as Cabir, have become the onslaught of rampant mobile phone intrusions, something that uses the Bluetooth connectivity as a means of infecting mobile phones of today. Once they get through, malfunctions and error messages are sure to ensue, making it a need for the software systems of mobile phones of today to be either formatted or disinfected with available anti-virus and worm removers such as Panda Software.

Inconvenient as it may seem, it is advisable for mobile phone owners to refrain from activating their Bluetooth connections to avoid such infections and untoward intrusions at any time.

Careful of Unknown Links in Messaging

Written by Saran on July 6, 2010

Trojans hacks and worms can easily enter a person’s computer by a mere click of a link. Instant messaging, the new trend in adhering towards faster and easier communication anywhere in the world has been enhanced thoroughly, going to the extent of allowing links to be followed, sometimes generated automatically from infected computers. Such are done even when offline messages are left, such as in Yahoo Messenger issues.

Instant Messages

The best way to avoid such links is to refrain from clicking on links without prior notice from the actual user. While most people would rely heavily on the level of relationship that they would have with their online buddy, it is still best to double check and verify before proceeding on the site link.

Being infected is quite painful that it leads to even formatting the entire system. This holds true for people who are not aware or have the time to clean it manually and methodically. Hence, the best way is to be more cautious, especially when peculiar links are met.

Scan Storage Devices before Enabling

Written by Saran on October 27, 2009

Viruses and malware issues are far from being a thing of the past. On the contrary, they seem to grow large by numbers as each day passes. Thus the works of security software companies have their work cut out for them. There is not definite date to which such threats and intrusions would wholly be resolved.

Scanning Protocol

For the time being, it would be advisable for people to scan third party storage devices such as diskettes, USB drives and mobile storages to be safe and sound. These wandering viruses can attack at any time and this is a fact anywhere computer related materials are concerned.

Files can go as far as infecting the executable files, hence document, excel and compiled scripts are baits for immediate infection and malicious intrusions. Software applications also have their limits as their development teams cater only to a specific genre for known harmful files. But it is better to lower the risk of intrusion than not having protection at all.

Ants Versus Worms

Written by Saran on September 29, 2009

antNot everyone hates worms – the natural kind, that is. I still remember classmates from grade school (even high school!) who grossed out everyone else by eating worms in their natural state. I am talking about a different kind of worm here, though; the kind that everyone hates; computer worms.

Pretty soon, we just might have ants on our side to combat the threat that worms pose year in and year out. Researchers in the field of IT security have been working on a project to combat worms, drawing their inspiration from the common ant. The Daily Tech tells the story:

Security researchers found inspiration in the common ant. Describes Wake Forest University Professor of Computer Science Errin Fulp, “In nature, we know that ants defend against threats very successfully. They can ramp up their defense rapidly, and then resume routine behavior quickly after an intruder has been stopped. We were trying to achieve that same framework in a computer system.”

WFU created digital “ants” — utilities that migrate from computer to computer over networks searching for threats. When one locates a threat, others congregate on it, using so-called “swarm intelligence”. The approach allows human researchers to quickly identify and quarantine dangerous files by watching the activity of the ants.

The implications are tremendous. Anti-virus software that is commonly used today usually take up a lot of resources, and make computers slow down. With this new technology, we just might see a whole new breed of anti-virus programs. While everything is in the research and development phase still, it does give us a bright future in terms of fighting malware!

Google Chrome Even More Secure

Written by Saran on August 27, 2009

google-chrome-logoFrom Internet Explorer to Mozilla Firefox to Google Chrome – that’s the path that many computer users have followed in the past years. Personally, I have stuck to Mozilla but I do use Chrome every now and then when I want things to go much faster. But did you know that Google’s streamlined browser has its share of security issues as well?

This is not really that surprising. After all, most any product you see in the market will be exploited by those who want to do so. In any case, Google has come out with updates to their browser, making it more secure for us users.

The most recent update for Google Chrome fixes some issues on how the browser handles Javascript and XML. For the Javascript engine, the fix makes sure that an infected web site will not allow malicious Javascript to run arbitrary code. You and I know very well that the phrase “run arbitrary code” simply translates to “install malware.” With this problem supposedly fixed, Chrome is definitely safer.

Another fix deals with the possibility of a web page using XML to, again, run arbitrary code. This happens when the malicious XML crashes a Chrome tab.

Last, the Chrome update will not allow you to connect to “HTTPS (SSL) sites whose certificates are signed using MD2 or MD4 hashing algorithms.” The reason for this is that these algorithms are prone to hacking and that it is relatively easy to pose as a fake HTTPS site.

For more detailed info, read it from Google’s own blog.

One Out Of Six: Yes To Spam

Written by Saran on July 23, 2009

spamLast week, I found myself craving for Spam – the kind that you put in between two slices of nice white bread. The moment I checked my Inbox, though, my feeling towards spam – in general; food or e-mail related – changed drastically. For some reason, I keep getting these e-mails about Viagra and winning the lotto. And I am talking about my WORK e-mail here, not my personal e-mail! Seriously, I don’t understand why these people keep sending out these e-mails when everyone knows they’re SPAM and that they amount to NOTHING! No one pays attention to these e-mails, right?

Well, apparently, some people do! According to a survey conducted by Messaging Anti-Abuse Working Group, 1 out of 6 people in the United States and Canada respond to spam e-mails. I know, this is simply unbelievable, isn’t it?

In this day and age, why would anyone still fall for these scams? Haven’t we learned anything at all? No wonder that these scammers continue to send out their e-mails! I mean, just one or two people who respond to their bait might give them the profit that they are out for.

To be fair, the scammers are getting more and more creative. They also take advantage of the hottest things happening. For example, around the time of Michael Jackson’s death, there was an astronomical increase in e-mails about him – a lot of these were spam. Even those who are normally careful were lured into opening these e-mails and clicking away.

Bottom line: spam might be here for a while. Make sure you are careful and don’t be cocky (like me) – you never know what might hit you!

An Internet of Criminals

Written by Saran on June 29, 2009

Hacker NetworkThe world of cyber-crime has grown so much in these past few years due to the explosion of growth with respect to the number of internet users the world over. It has not only expanded on the side of normal people but on the side of cyber-criminals who now operate on their own networks, spanning the globe and ready to spread their products, malicious code that first scans the globe for weak points in the security net that we all put up to somewhat give us a sense of security from the ever-growing threat which is actually futile to some extent.

Microsoft To Launch Free Security Software

Written by Saran on June 20, 2009

microsoft-antispyware-beta-security-internet-softwareCool! But wait – Microsoft is giving away something for FREE? Am I dreaming? You better believe it, though. The software giant is jumping into the freeware fray with their latest security product. Dubbed Microsoft Security Essentials, the program is designed to detect, find, and kill malicious software that might find its way into your computers.

The beta version will be released next week. In the meantime, the company is continuing to develop the full version of the product, which is slated to be released in the fall. The security software is not going to be bundled with Windows 7, as this may provoke anti-trust issues, which Microsoft has had more than its share of. Still, critics have not been slow to point out that the description of the product is flawed and misleading.

David Cole of Symantec has stated that it is NOT an essential security solution. He also pointed out that users still need protection such as firewalls, spam fighters, and other features that are included in subscription products.

So what does Microsoft Security Essentials really offer? According to Theresa Burch, the program will try to spot malicious software, even if it is not part of the database of known threats. Once the suspicion of the software is aroused, it will first check with online servers before allowing the program to run. Users do not have to worry about the program interfering with trusted sources, however, as there will be a list of those, such as Google Toolbar.

I think I’ll see what it has to offer next week.
