IM to Spread Malware: the Butterfly Effect

This weekend, an unnamed worm forced Microsoft to temporarily suspend active links  in Live Messenger 2009, in order to prevent the aggressive worm from spreading further. This is quite a surprising measure, because worms spreading through Instant Messaging (IM) such as Skype, Yahoo! Messenger and Microsoft Live Messenger are not new at all! For example,

Boonana Threat Analysis

Our interim analysis of a version of the malware we detect as Java/Boonana.A or Win32/Boonana.A (depending on the particular component of this multi-binary attack) differs in some characteristics from other reports we've seen. The most dramatic difference is in the social engineering hook used in messages sent to an infected user's friends list. Other reports

Imitation is not always the sincerest form of flattery

Since its release in 2007, ESET Smart Security has received many accolades for its antimalware, antispam and firewall functions.  However, we have recently been the recipient of a very dubious honor; a rogue antivirus program which masquerades as our own software. The Rogues Gallery Rogue antivirus is a loose family of programs that claim to

Privacy? Who Cares?

In the security industry, we’re sometimes over-ready to be over-prescriptive, seeing security and privacy concerns as paramount where others see them as a distraction. And we’ve become used to the mindset that computer users will always prefer convenience to security.

One Billion Blocked – Malware and IE 8

Every layer of protection you add will harden the target against cybercrime. SmartScreen technology found in Internet Explorer 8 has recently clocked over 1 billion blocked potential malware downloads from malicious sites. By way of Terry Zink’s blog: 1 billion malware blocks is an amazing milestone and an example of two things. First socially engineered

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

FBI Cyber Division Warns About Social Networking

In response to questions I heard this weekend from friends of mine about the ‘big picture’ relevance of the 1.5 million Facebook accounts compromised, I referred back to last month’s FBI speech from Dep. Asst. Dir. Chabinsky: “Don't be surprised if a criminal compromises your or one of your colleague's personal social networking accounts to

Facebook checked out, 1.5 million accounts overdue for password changes?

The Internet is abuzz with the announcement from Verisign’s iDefense Labs that a criminal hacker on a Russian forum who goes by the nom-de-plume "Kirllos" (Carlos?) is selling the credentials for 1.5 million Facebook accounts in batches of a thousand for between $8 and $30, depending upon their quality (which, in this case, means dates

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

Dangerous Zips + Responsible Disclosure

Mario Vuksan, Tomislav Pericin and Brian Karney have been talking…about vulnerabilities they’ve found in various compression formats … as well as their potential for steganographical use or misuse…. Perhaps the main problems here will not be technical vulnerabilitiese but careless users and social engineering attacks.

PDFs Exploitable?!? I’m shocked…

September 2009 saw some key security analysis raining directly onto the Adobe PDF platform, particularly with SANS pointing towards remote code execution within PDFs as one of the top threat vectors: Adobe Acrobat, Reader, and Flash Player Remote Code Execution Vulnerability (CVE-2009-1862) Adobe Reader Remote Code Execution Vulnerability (CVE-2009-1493) Kudos to Adobe for patching these

Russian Metro Bombings: Here come the Ghouls

[Interim updates removed: later information on Twitter profile attacks and Blackhat SEO attacks using keywords related to this topic to spread malware, has been made public in a later blog at http://www.eset.com/blog/2010/03/30/here-come-more-of-the-ghouls.] Following this morning's bombings in the Moscow Metro (subway system), Aryeh Goretsky suggests the likelihood of criminals using "blackhat SEO" (search engine optimization

World-Cup Malware: the Kick-Off

Looking into their crystal balls (no jokes, please) at the end of 2009, our colleagues in Latin America came up with a prophecy that was later incorporated into a white paper (2010: Cybercrime Coming of Age): In June 2010, one of the most popular regular sports events, the soccer World Cup, will take place in

Don’t Be A Twit

There's a news item out at the moment about how a French man has been arrested for a host of Twitter account attacks including the accounts of US President Obama and Britney Spears. It seems the hacks were carried out in April last year and the arrest came about after collaboration between the US FBI

iPad scammers target the unwary

The Apple iPad is the current gadget du jour amongst the digerati and has been seeing strong presales, with estimates as high as 150,000 units on the first day.  With such attention in the media and the blogosphere, it is no wonder that both legitimate businesses and scammers have taken to using it as bait

Dumb or Devilish? You Decide…

[Update: so far I have two votes for dumb. Maybe I'm giving this spammer too much credit, and it is a simple "spam template fail" ;-) On the other hand, while I wouldn't vote "evil genius", I'd still love to know how many people actually fall for this - I don't have a problem envisaging

The Return of Jacques Tits

It has been a year since we last discussed fraudulent domain name registrar scams and we wanted to let people know that this scam continues unabated. In a nutshell, a message is sent to a publicly-visible email address listed on your website (sales, support, the CEO's office, a public relations contact, et cetera) from a

You are the weakest link…

Greetings, friends and fiends. It's been a while since I've been able to blog: I've been trying out one of these vacation thingies that I keep reading about in travel magazines. (Well, my wife does, and she tells me when I need a holiday, presumably as my conversations get grouchier.) But I see that my

Hmmm, Phishing Works

Specifically spear-phishing, where the target is deliberately selected, as opposed to a random untargeted attack. An article at Dark Reading.com discusses the entirely unsurprising results of a test that concluded that the iPhone, BlackBerry, and Palm have essentially no protection against spear-phishing attacks. http://www.darkreading.com/insiderthreat/security/app-security/showArticle.jhtml?articleID=221100150&cid=nl_DR_WEEKLY_T LinkedIn was used as the service to send a fake invitation

Cybersecurity Awareness Month – Awareness for the Next Generation

"Now may I suggest some of the things we must do if we are to make the American dream a reality. First, I think all of us must develop a world perspective if we are to survive. The American dream will not become a reality devoid of the larger dream of brotherhood and peace and
