We are not Zimused – a few updates

My colleague Juraj Malcho, head of lab in Bratislava, has clarified a point: what Zimuse actually does is fill the first 50Kb of a targeted disk with zeroes (actually the 0x00 character): This does indeed overwrite the MBR, but also overwrites anything else that occupies that area of the disk. The malware came to ESET's attention because

Solución al octavo desafío de ESET

El objetivo del octavo desafío era aprender a mirar y ver en el código fuente, acción que se debe llevar a cabo con atención cuando se busca sitios web o páginas comprometidas. La respuesta correcta es “YO GANE” y se encuentra dentro del archivo de texto plano 8723g8738g73.txt codificado en formato HTML y al que

Scam en nombre de ¿ESET?

En los últimos días hemos detectado gran cantidad de correos electrónicos con mensajes del tipo scam. Al igual que con los ataques detectados hace unos días, utilizando los nombres de Microsoft y BMW en los falsos mensajes como técnica de Ingeniería Social para captar la atención del usuario; en esta ocasión están circulando nuevos mensajes

A Trojan Anniversary

I don't suppose anyone remembers my mentioning this before, or cares much anyway, but the 19th of December marks what I consider to be the 20th official anniversary of my entry into the anti-virus/security field. Nowadays, viruses (and, in general, worms) have declined in importance and now constitute a fairly small proportion of the totality

Microsoft Security – Essential?

People keep asking me about Microsoft’s newly released Security Essentials free anti-malware (formerly known as Morro). Randy and I both blogged about it at some length back in June – see http://www.eset.com/threat-center/blog/category/microsoft-security-essentials and http://www.eset.com/threat-center/blog/2009/08/03/more-free-lunches, for instance – but there’s still a lot of interest in the impact that the product is likely to have on ESET

Turkish Delight

So, back in harness. I’ve been away for a couple of weeks: not on holiday as such, though I did take some days out, but concentrating on writing: it didn’t hurt that I didn’t have a full-strength internet connection to distract me, though. Before I left, I was interviewed by a Turkish security site. It

ThreatSense.Net® Report for July

Our July ThreatSense.Net® report has been released today, and will eventually be available from the Threat Center page here. Most of the top ten entries are old friends: well, familiar names might be a better way of putting it. One of the disadvantages of having a scanner that makes heavy use of advanced heuristics is

Fly By Wireless

No, nothing to do with drive-by downloads… Our colleagues in Europe came up with a nice idea: an article on the dangers of web surfing on free wi-fi and some tips on staying safe. (A topic dear to the hearts of all of us who find ourselves out and about with our laptops from time

Research and Support

Following up on blog comments is part of the job for those of us contributing to the ThreatBlog. Well, I suppose it is: no-one else does it if we don’t. :-) Much of the time, comment handling involves dealing with the occasional comment spam that slips through our filters (there’s an interesting item on a novel

Support Requests

Just a reminder that we can’t usually handle support issues here. Not that we want to be unhelpful, but the Research team simply isn’t resourced for that sort of work. Someone just posted a problem they had with V.4 here, and I mailed them back, but the message bounced, so I’ll summarize here. As it
