MacDefender: The sky is not falling…

In the last few days, I have been asked by a journalist (or four) what MacDefender means for the future of Apple security, and if I thought there was excess hype around it.   I'll address the second question first.   I think its safe to say the current malware would not be newsworthy if

MacDefender (now MacGuard) Can Install Without Credentials

The recent MacDefender Trojan has been receiving “rebranding” facelifts since it came out. It has now been deployed as MacProtector, MacDetector, MacSecurity, Apple Security Center, and there are no doubt more iterations to come. The malware has been updated, and now sports an improved UI that looks like a native Mac OSX application, unlike the

Yesterday’s Virus Hoax is Today’s Fake Utility

One of the (few) blessings of having been so long in this industry is that I remember a time when most malware was viral and Trojans were rare: so rare, in fact, that there was at one time a notorious "dirty dozen" set of Trojans.  At around the same time, there were innumerable hoaxes describing malware with

Coreflood dries up

The US Department of Justice's announcement yesterday of the takedown of the command and  control (C&C) servers for the Coreflood bots (detected by ESET as Win32/AFCore) and seizure of their domains marks another step in the growing awareness that crime, whether it is committed with bullets or with botnets, is still crime.  This particular botnet,

Hacking by Proxy

The BBC program Panorama last night investigated claims that the News of the World hired a hacker to break into a subject's PC to steal emails. In fact, it appears that the unnamed hacker installed a Trojan on the victim's PC. Which sounds like a fairly unequivocal breach of the Computer Misuse Act, which outlaws

Trojan in Microsoft Update Catalog – A Bunny Bites Back

UPDATE #1 Randy Abrams has posted a follow-up article, Anatomy of a Biting Bunny – The Infected Microsoft Catalog Update with additional information about how update services work, why they might distribute third-party code and what might be done to prevent malware from being distributed on services like Microsoft’s Windows Update in the future.  7-FEB-2011. Last week, we

Stock Manipulation Botnets Gain Ground

The attacks from cybercriminals are now occurring in the online stock and equity trading world. Instead of simply emptying out compromised brokerage accounts, cybercriminals apparently are refining their attacks and striking at broader and more lofty goals: the trust mechanisms of business equity valuations with publicly traded stocks and equities. George Hulme, InformationWeek contributing writer

European Cybercriminal Gangs Target Middle America SMBs

 Better get your CFO to review UCC Article 4A and realign protocols with your business bank – The clear and present danger to our banking through malware hits at the heart of our economy: the SMB. Stealthy malware-based theft of funds start the clock ticking much quicker than most SMB owners realize and without action

Another Look at Koobface: How It Infects Facebook Users

Earlier this month, we reported on the massive new Koobface campaign making the rounds through Facebook and how it tricked users into downloading and running it through that tenet of social engineering, the fake codec. We now have a video showing how the Koobface worm tricks users into running it: NOTE: The audio is not

Anniversaries Galore

Following my blog at http://www.eset.com/threat-center/blog/2009/12/18/a-trojan-anniversary, I came across a blog by Kurt Wismer that picked up the theme. As it happens, though I don’t think we’ve ever met, Kurt and I have corresponded from time to time for quite a few years (fourteen, apparently), so I guess it’s not so surprising that he also dates

September’s Global Threat Report

ESET released its Global Threat Report for the month of September, 2009, identifying the top ten threats seen during the month by ESET’s ThreatSense.Net™ cloud.  You can view the report here and, as always, the complete collection is available here in the Threat Trends section of our web site.  While the report identifies a number

Not all Mac users are naive about security

I’m often exasperated by blinkered mindsets in the Mac community, of the security-related kind that Randy highlighted in a recent blog. You might have picked up a certain irritation in some of my blogs around the end of last month relating to Snow Leopard and malware detection, too. So it was refreshing to come across a light

Magic Lantern Show in the UK?

Nigel Morris, of the UK’s “Independent” newspaper reported recently on new powers given to police in the UK and proposals to extend similar powers across the European Union. Understandably, civil rights groups like Liberty have apparently expressed the belief that such expansion of “police hacking operations” should be regulated by Act of Parliament and that there

Sending Malware Information to ESET

I’ve just picked up a comment to a previous blog that pointed to what I presumed to be a malicious URL. We’re grateful for all such information, but for obvious reasons, we won’t approve comments that point to malicious code! You can find information here about how to forward malware samples, malicious URLs or false positive

Anti-Malware Testing Resources

...after many years of campaigning for better testing and better information about testing, it feels very positive that people are prepared to sit through a 60 minute presentation and then go on asking questions for another half hour...

Watch Out For Good Download Sites

CNET, who hosts Download.com, has enjoyed a reputation for being a safe place to download software from. The program you download may be great or may be useless, but it had been “Tested Spyware Free.” At least that is what Download.com says about their downloads. Today it has come to my attention that the site

Giving (Samples) to Charity

Recently we noticed a thread in a forum associated with a free security product, originating in an open letter to a well-known tester, asking him to donate his sample set for the improvement of the product.
