Much Ado About Facebook, Part II

Since yesterday’s Much Ado About Facebook post in the ESET Threat Blog, we have written additional articles, received a few comments, and also received updated information on the “threat,” so it seems that now is a good time for a follow-up article.  Reports continue to come in of pornographic and violent imagery on Facebook, and

Made in the Czech Republic: a PHP Autorun worm

Recently, a new data-stealing worm caught our attention. The reason why it stands out from many similar amateur creations is that its author is most probably Czech, as the text strings, variable and function names used by the malware suggest. The Czech text above is displayed by the worm inside a console window and translates

1000 days of Conficker

Nearly three years old, the Conficker worm continues to pose a threat to PCs. Aryeh Goretsky wants to know why this is, and what can be done about it.

Where there’s smoke, there’s FireWire

Forensic software developer PassWare announced a new version of its eponymous software forensics kit on Tuesday. Already several news sources are writing about how the program can automatically obtain the login password from a locked or sleeping Mac simply by plugging in a USB flash drive containing their software and connecting it to another computer

Comenzó el malware de San Valentín

Febrero es un mes que se caracteriza por celebrar uno de los eventos que tiene gran relevancia a nivel mundial: el día festivo de San Valentín, también conocido en algunos países como el “día de los enamorados“. Celebrado el 14 de febrero, este logra despertar un interés particular en la sociedad, por ser la festividad

Stuxnet: the Never-Ending Story

…The NYT article strikes me as being well-researched, well-written, and well worth reading, and the involvement of Dimona is more plausible than much of the speculation I’ve seen, but it’s still hard to distinguish hard fact from sheer guesswork…

Is Barbie the Pedophile’s Best Friend?

A recent story http://www.telegraph.co.uk/news/worldnews/northamerica/usa/8180442/FBI-warns-Barbie-camera-could-be-used-by-paedophiles.html tells of a leaked FBI memo about the perils of a new Barbie doll. It appears that the new Barbie comes equipped with a web cam that can allow children to send videos of themselves across the net. The FBI, rightfully so, worries that this may be a weapon of pedophiles

Sality se suma a la vulnerabilidad LNK

Luego de las repercusiones sobre Stuxnet, explotando la vulnerabilidad CVE-2010-2568, a la cual se sumaron dos familias más (Win32/TrojanDownloader.Chymine.A y Win32/Autorun.VB.RP) y la incorporación del exploits a un crimeware (Zombie Explotation Kit), recientemente se ha descubierto otro código malicioso que utiliza esta debilidad para infectar los sistemas de información. Se trata de Sality, un peligroso

Aparecen nuevas familias de malware explotando vulnerabilidad 0-Day "LNK"

Cómo adelantamos en estos días a modo de tendencia, nuevas familias de códigos maliciosos han aparecido empleando como vector de ataque la misma vulnerabilidad 0-Day (CVE-2010-2568) utilizada por Win32/Stuxnet.A. Investigadores de ESET han identificado en las últimas horas dos códigos maliciosos más relacionados con la explotación de la vulnerabilidad en cuestión. Se trata de la

Which Army Attacked the Power Grids?

The hot news http://blog.eset.com/2010/07/17/windows-shellshocked-or-why-win32stuxnet-sux is of a zero-day vulnerability that has been used to attack SCADA systems. This comes hot on the heels of an article on the Wired web site titled “Hacking the Electric Grid – You and What Army” http://www.wired.com/dangerroom/2010/07/hacking-the-electric-grid-you-and-what-army/. So clearly Wired had already predicted the origins, at least vaguely, of Win32/Stuxnet.

(Windows) Shellshocked, Or Why Win32/Stuxnet Sux…

…But that doesn’t mean that this particular attack is going to vanish any time soon, AV detection notwithstanding. Now that particular vulnerability is known, it’s certainly going to be exploited by other parties, at least until Microsoft produce an effective fix for it, and it will affect some end users long after that…

Microsoft Takes the Security out of Security Conferences

In May it was reported that IBM handed out some USB drives that were infected. A month later I spoke at a security conference that I will not name. I gave the AV (audio/visual) technician a USB key with my presentation on it to copy to the laptop they were using for the presentations. About

Do You Have a Process?

USB thumb drives, such as those pictured below from www.promotionalpro.com, are very popular marketing item, but oftentimes people are not aware of the digital risks these devices can present. In recent years many USB devices have been sold or given way only to be found to be pre-infected from the factory. At a recent security

Should I Stay or Should I Go?

I don’t really want to leave ESET, but IBM needs me. Several years ago Microsoft had a serious problem with viruses in its software. I was given the task of making it go away. It started with retail software. My job was to make sure none of the retail software Microsoft released was infected. Then

Autorun and Windows 7

Autorun and Windows 7. Long time readers know that I think autorun was Microsoft’s longest unpatched vulnerability. For Windows 7 Microsoft has made some serious improvements, but for older versions of Windows Microsoft has ignored the obvious vulnerability and only offered the patch as an optional download instead of making it a critical update, as

Guest Blog: How free is free Antivirus?

I've noticed a number of tests recently that seem to be intended to prove that free antivirus is as good as commercial AV. As it happens, I'm not against free AV in principle, as long as people are entitled to use it – commercial use of free AV is usually not permitted. And I'm overjoyed when

The Biggest Botnet in the World

You may have seen the news about the bot masters in Spain who were arrested. Defense Intelligence http://defintel.com/docs/Mariposa_Analysis.pdf dubbed this Mariposa botnet. It is claimed that this botnet had the power to perform much stronger attacks than what Estonia witnessed a couple of years ago.  Still, this botnet is dwarfed by the largest botnet in

NOD32 Antivirus for Mac: Some Questions

These are a few questions relating to ESET's antivirus scanner for OS X, which is currently in beta, that I was asked in response to a post at Mac Virus. (If you want to take the beta out for a spin, you can still download it at http://beta.eset.com/macosx.) As these questions are very ESET-specific, I

Anti-Malware: Last One Out, Please Turn Off The Lights

It doesn't surprise me when someone says, like David Einstein of the San Francisco Chronicle, that there's no need for a Mac user to run anti-virus software. Though the most usual reason I see given is that there aren't any Mac viruses. (There are, but nowadays the main reason to run anti-malware on any platform

End of Year, End of Decade

As our December ThreatSense report (now available at http://www.eset.com/threat-center/threat_trends/Global_Threat_Trends_December_2009.pdf) was not only the last of the year but the last of the decade, it's rather longer and more detailed than usual, including a look back at the last 12 months. I suppose we could have gone back over the whole decade, but I have to
