Hesperbot – A New, Advanced Banking Trojan in the Wild

A new and effective banking trojan has been discovered targeting online banking users in Turkey, the Czech Republic, Portugal and the United Kingdom. It uses very credible-looking phishing-like campaigns, related to trustworthy organizations, to lure victims into running the malware.

The Powerloader 64-bit update based on leaked exploits

A few months ago on this blog I described PowerLoader functionality – including an interesting way for privilege escalation into the explorer.exe system process. The leaked PowerLoader code is also used in other malware families.

Java has been – and still is – one of the more problematic issues security-wise. A website showing song lyrics from Golden Earring’s Radar Love shows off problems that can leave users at the mercy of Java attacks.

Catch me if you can: Can we predict who will fall for phishing emails?

A new paper aims to profile the victims most likely to fall for a phishing attack. But what is less clear is how you develop a profile while avoiding the pitfalls of stereotyping.

Versatile and infectious: Win64/Expiro is a cross-platform file infector

Recently, our anti-virus laboratory discovered an interesting new modification of a file virus known as Expiro which targets 64-bit files for infection. File-infecting viruses are well known and have been studied comprehensively over the years, but malicious code of this type almost invariably aimed to modify 32-bit files. One such family of file viruses, called

The London Scam and the Londonderry Air

My colleagues at ESET Ireland, report that an all-too-familiar scam is currently hitting Irish mailboxes. I’ve talked about it at some length here previously – for instance here and here – but here’s a quick summary. Someone, apparently someone you know (a friend or a family member) contacts you to tell you that they’ve been

Darkleech and the Android Master Key: making a hash of it

I made a comment recently that was subsequently quoted in a recent ESET blog – Android “master key” leaves 900 million devices vulnerable, researchers claim – and it appears that comment may have confused one or two people. What I actually said was this: “Security based on application whitelisting relies on an accurate identification of

The Fresh Prince of Bel-Where? – Academic Publishing Scams

[A shorter version of this article was originally published - without illustrations - on the Anti-Phishing Working Group’s eCrime blog.] Phishing attacks targeting academia aren’t the most high-profile of attacks, though they’re more common than you might think. Student populations in themselves constitute a sizeable pool of potential victims for money mule recruitment and other

The Home Campaign: overstaying its welcome

The Home Campaign is a malware campaign that uses a modified variant of Darkleech to direct visitors to the Blackhole exploit kit. We want to give a better idea of the size and extent of this campaign.

Support Scams: we don’t really write all the viruses…

…and nor are we responsible for fake AV/scareware and (more recently) ransomware, though I did suggest in a paper I presented at EICAR a couple of years ago that the bad guys who do peddle that stuff are all too proficient at stealing our clothes, and that maybe some security companies were making it easier

Needles and haystacks – the art of threat attribution

ESET researchers explain the difficulties in attribution of targeted attacks; evidence is often circumstantial and the source never positively identified.

Operation Hangover: more links to the Oslo Freedom Forum incident

In our previous post on Operation Hangover, we revealed the existence of an attack group, apparently operating from within India, who were mainly targeting systems in Pakistan. In this post, we will analyze the Mac OS X samples that have been linked to this group and will provide new evidence that the Mac and Windows spywares are related.

Intellectual property protection and good badware

As an earlier article here noted, the recent report from the Commission on the Theft of American Intellectual Property shows a great deal of concern about the “scale of international theft of American intellectual property” which it estimates to be “hundreds of billions of dollars per year.” However, there’s also been a certain amount of

Phishing: the click of death

Recently we realized that from time to time when people find a live link in one of our blogs, they click on it to see where it goes, even though the context might suggest that the link could be malicious. So we thought it might be a good idea to set up a link so
