The Induc Virus is back!

ESET has discovered a new version of the Delphi infector, Win32/Induc. Unlike its predecessors, however, this variant incorporates a seriously malicious payload and has acquired some extra file infection and self-replicative functionality. Two years ago, we published comprehensive information (here , here, and here) about the virus Win32/Induc.A, which infected Delphi files at compile-time. Though

Manga Management and Malware

…one Yasuhiro Kawaguchi was arrested yesterday on suspicion of “saving a virus on his computer,” though the story suggests distribution of malware too…

The more things change, the more they stay the same

It's something of a truism, that 'old viruses never die', and that certainly seems to be the case for some of the older, more widespread, email worms. In this interview (http://www.signonsandiego.com/uniontrib/20041129/news_lz1b29five.html) back in 2004, I talked about an email worm called "Win32/Zafi.b" which, at the time, had recently been spreading on a global scale. However,

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

What are Heuristics?

It is generally well-understood that antimalware programs—the software which detects computer viruses, worms, trojan horses and other threats to your system—work by scanning files using signatures they already have. A signature could be as simple as a string[i] (like using the "find" command in your word processor to locate a particular piece of text) or as

Viral Implants (not what you think)

There was a bit of a stir today around a British scientist, Dr. Mark Gasson. In the BBC article Dr. Gasson was touted as the “First Human ‘Infected With a Computer Virus’”. I let this one stew around for a few seconds and I have to say that this isn’t what it’s cracked up to

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

And talking of Cyber Monday…

Even in Europe, we have a rough idea of what Thanksgiving is about, though we don't celebrate it at the same time or in the same way. However, Black Friday and Cyber Monday are rather less well known outside the US. Since Randy has already blogged on Cyber Monday and its security implications at http://www.eset.com/threat-center/blog/2009/11/19/is-cyber-monday-the-end-of-shopping-as-we-know-it, I took the

The Blame Game

I recently learned a new acronym: SODDI (Some Other Dude Did It). What this refers to is the defense that criminals routinely use (plausible deniability) – and even more so when it comes to illicit activities on the Internet. On Sunday, November 8th 2009 the Associated Press published an article regarding an individual that was

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

The Retro-Virus

Nowadays we see lots of malicious software that is designed to steal money and information. A new virus was recently discovered that seems to be all about proving a concept rather than blatant maliciousness. The Win32/Induc.A virus does not infect like most viruses do. Delphi is a programming language. Induc infected the Delphi IDE so

Microsoft Beta Than ESET?

I really didn’t think that Microsoft’s beta AV product would necessitate three blogs: it is, after all, just a beta release. However, I was surprised just now to read an article by Mark Mayne of SC Magazine that claims the product is “going head-to-head with a range of AV vendors, from Symantec and McAfee through

Antivirus Doesn’t Work

  Yesterday at the EICAR conference in Berlin <http://www.eicar.com> Dr. Fred Cohen was the keynote speaker. For any of you who do not know of Dr. Cohen, he is credited with coining the term virus to describe a self-replication program. Dr. Cohen also is credited with writing the first computer virus. The virus was written

Confused about Conficker?

CNN reported that there a new sleeper virus out there. http://www.cnn.com/2009/TECH/ptech/01/16/virus.downadup/index.html There is nothing sleepy about the Conficker worm, it is wide awake and looking for people who are asleep at the security wheel. CNN reports that Conficker could allow hackers to steal personal and financial data, and they also report that it “it is

You Did Back Up Your Data, Didn’t You?

One of the security best practices is to back up your data regularly. This is sound advice as it helps mitigate the damages from many different threats. Lots of people think of data loss when they think of viruses, but very few viruses actually tried to cause data loss. There have been a few that

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 in our knowledgebase here about how to forward malware samples or false

Spies in One’s Samovar (or a Storm in a Teapot)

Round here, we’re mostly concerned with the malicious and programming kinds of bug. But as an avid watcher of Spooks*,  I couldn’t resist sharing with you an item in the Telegraph about a samovar presented to the British Royal Family about twenty years ago. Apparently, after a surveillance sweep of the Queen’s estate at Balmoral, the

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…

Microsoft to Give Away AV Software

Microsoft announced that they will be dropping OneCare and providing a free consumer anti-virus product. Much like when Microsoft announced they would enter the anti-virus market, this has caused quite a bit of media buzz. Much like when Microsoft announced they would enter the anti-virus market, this is not a big deal. To start with,
