Twitter Account Suspended? Be Careful What You Post

Martin — Mon, 12 Oct 2009 15:49:01 +0000

You might have already read about it in the news elsewhere: The Twitter account of security researcher Mikko H. Hyppönen of F-Secure got suspended without warning two days ago. Mikko tried to contact Twitter support and tried everything in his power to understand why his Twitter account was suspended in first place. He received a short message by a Twitter representative after two days that mentioned why his account was suspended and that it was unsuspended.

Here is how Mikko describes what happended in his blog: He posted a warning about a new MySpace phishing website two month ago as a tweet using his Twitter account. This message contained an unclickable url of the phishing website to warn users and spread the word.

Twitter, after two months, figured that the url was a phishing url and made the decision to suspend the account. It is not clear if this was an automatic or manual suspension. The Twitter account of Mikko was restored after two days and the following explanations was given:

I’ve unsuspended your acct.
You were suspended for using the malware URL rnyspeceDOTcom in DMs.
Be careful!
We scan evrythng for malware.

To make matters worse all of his followers and people that he followed were not restored. Both counts showed 0.

The whole incident raises several questions:

Why was the Twitter account banned after two months and not immediately?
Why did no one notify the Twitter user about the suspension
Why did it take two days to restore the account
Why can’t the followers and followed be restored

Twitter’s reaction fell short and put the blame on the Twitter user rather on an ineffective way of handling the incident. Until things change Twitter users should be very careful what they post in Twitter.

How To Run Commercial Antivirus Software Without Paying For It

Martin — Fri, 25 Sep 2009 13:54:20 +0000

This article is not about illegal methods of obtaining software products. But read on if you are interested in how you can protect your computer with the latest antivirus software without having to pay for it. The principle is simply. Most antivirus companies are offering test versions of their products. These versions can usually be tested for 30 or 90 days. All you need to do to protect your computer with antivirus software is to install a new product every 90 days. This means that you need four antivirus products, preferably the most reliable ones that are offering 90 days of testing. You start again with next year’s edition of the first antivirus software that you started with. If there are not enough 90 day trials you switch to 30 day trials instead or use a free antivirus software to fill gaps in the 12 month cycle.

The following links point to antivirus software programs that can be downloaded as trial versions. These trial versions can be used for either 30 days or 90 days without payment.

Which antivirus software developers are offering 90 day trials?

McAfee VirusScan Plus [link]
McAfee Internet Security [link]
McAfee Total Protection [link]
Norton Antivirus [link]
Norton 360 [link]

Which antivirus software developers are offering 30 day trials?

Kaspersky Antivirus [link]
Kaspersky Internet Security [link]
Bitdefender Antivirus [link]
Bitdefender Total Security [link]
Bitdefender Internet Security [link]
ESET Smart Security [link]
ESET Nod32 Antivirus [link]
Trend Micro Internet Security Pro [link]
Trend Micro Internet Security [link]
Panda Security Antivirus [link]
Panda Antivirus Pro [link]
F-Secure Internet Security [link]
F-Secure Antivirus [link]

Please let us know in the comments if we have missed a product.

Some notes: This article does not rate the antivirus software programs. There might be free programs out there that are comparable to the listed antivirus products. The only problem with this method is that users need to install different antivirus software regularly. This not only means more work for the user but also the requirement to get used to new software products.

Many antivirus companies are running promotions every now and then that offer longer trial versions for download. This will obviously help tremendously.

Any thoughts or ideas?

F-Secure Health Check 2.0 Beta Ditches ActiveX

Martin — Thu, 24 Sep 2009 22:08:31 +0000

F-Secure Health Check is a web application that can perform a health check of a local Microsoft Windows operating system. A health check is basically divided into three areas of interest that are checked and an assessment in the end that lists possible solutions to the problems encountered. Area one will check for installed security software and display information about their state, e.g. if an anti-virus software or desktop firewall is installed and turned on.

Area two will do the same for backup software. It will list installed backup software and inform the user about the state that the installations are in. Area three which is probably the most interesting one to many Windows users will check various critical software programs and compare their version with the one in the F-Secure database. Health Check in this step checks programs like Microsoft’s Internet Explorer, the Adobe Flash plugin, Mozilla’s Firefox or Sun’s Java runtime.

The information in the solution tab obviously depend on the results of the system scan. A solve button will be displayed if problems have been found in one of the areas that have been investigated by the program. The solutions do fall a bit short, at least in the security tab as the program suggests to use F-Secure products to solve the problem.

It is only natural that a company wants to promote their products. The web application would however be useful to more users if they would have added some choice to the diagnosis. The new beta version of F-Secure Health Check 2 has ditched Microsoft’s ActiveX technology for Java. This means that it is now compatible with a wider range of Internet browsers. The developers list Internet Explorer and Firefox only but it has been successfully tested with Google Chrome as well which increases the chance that other web browsers that support Java will run the application fine as well.

Users who want to give F-Secure Health Check 2 Beta a try can go to the F-Secure website to run it from there.

F-Secure Exploit Shield Protects Against 0-Day Web Browser Exploits

Martin — Sun, 23 Aug 2009 10:00:45 +0000

One of the major security threats that computer users face in the last years are web browser exploits. These exploits use 0-day vulnerabilities to infect web browsers that have not been patched to protect against the vulnerability. It does not always have to be the user’s fault if a web browser has not been patched yet. It can take hours or even days before browser developers are able to release a patch that is protecting the web browsers leaving the browsers vulnerable to attacks in the time between.

Some plugins and add-ons help against these types of exploits and attacks. Notable is for instance the NoScript add-on for the Firefox web browser which disables script unless the user has explicitly given permission. The problem with these exploits on the other hand is that they might appear on trusted websites in the form of manipulated banner advertisement.

F-Secure Exploit Shield could be the solution against most of these attacks and exploits. The security software program, which is currently offered as a beta version for Microsoft’s Internet Explorer and Mozilla Firefox, uses a vulnerability shield and proactive measures to protect computer systems against these forms of attacks,

Vulnerability shields offer patch equivalent protection. They are usually hotfixes created by F-Secure employees that protect against known web browser exploits. The proactive shield on the other hand uses heuristics to identify and block unknown or unidentified web browser exploits.

F-Secure Exploit Shield can be downloaded from the Labs section of the company’s website. It is currently compatible with 32-bit editions of Windows XP, Windows Vista and Windows 7 and protects Mozilla Firefox and Internet Explorer web browsers on these computer systems.

F-Secure Health Check

Martin — Sun, 20 Apr 2008 12:43:27 +0000

Many companies are producing tools that scan the computer for security vulnerabilities. Some provide their functionality on a website while others are applications that have to be installed on the computer. F-Secure Health Check is a product of the first category. It provides access to a scanner that checks the operating system and installed applications for vulnerabilities and outdated versions. Unfortunately though the health check only runs on Microsoft Internet Explorer 6 or newer with Active X enabled.

An Active X control has to be downloaded prior to the scan. A health report is generated in the end that is displaying red, yellow and green icons in various categories. Red items are critical, yellow medium and green safe. My test results have been mixed. I did receive several red icons in some categories because of programs that were not included in my security concept. The red icon in the security products category for instance was there because of the disabled Windows Firewall and no other firewall that was installed.

It did not detect the hardware firewall of my router. What I want to say is that even though some elements are marked as insecure they might not be in your special case. Another example was the yellow icon in the Sending Mail category which was there because of an old backup version of Eudora 5 which I do not use anymore. I think I did receive a yellow rating because of two up-to-date email applications (Thunderbird and Outlook Express).

The most interesting categories in my opinion are the following two: Opening multimedia files and documents & Using other programs. It did detect some outdated applications (that I do not use regularly or forgot about). What I really like is the option to solve the issue right away by clicking on the solve button. This normally leads to a page where the updated application or patch can be downloaded.

It does not take long to update all the applications listed this way. F-Secure Health Check is an interesting service that excels in solving issues that have been found. A pity that it only works in Internet Explorer and that it requires Active X.
