Could distributed denial of service (DDoS) malware be evolving to defeat anti-DDoS security measures like CloudFlare? We do not usually see a lot of innovative denial-of-service malware in our day-to-day work. What we do see usually boils down to the basic flooding techniques: TCP Syn, UDP and ping floods, and sometimes HTTP-oriented floods. Of course,
ESET’s threat researchers received a surprise earlier this week when they began receiving reports from ESET LiveGrid that downloads of ComboFix, a tool popular with advanced users for removing malware, were detected as being infected by a variant of the Sality virus, Win32/Sality.NBA.
I received a “shared” messages from a friend about “a leaked scandal video of Justin Bieber and Selana Gomez” promising a “naked Justin Bieber”, with a Photoshopped picture, which we – for family-friendliness – censored a bit.
In various blog-posts, users have been encouraged by ESET experts to download applications from the official website for that application, as you never know what might have happened to the software when you download it from a mirror site or a download site.
Does your Apple Mac need antivirus software, or any other kind of security software? This question has been asked repeatedly over the years and I think the “correct’ answer has changed over time.
Malware authors have a solid track record in regards to creative Command and Control protocols. We’ve seen peer-to-peer protocols, some custom (Sality), some standard (Win32/Storm uses the eDonkey P2P protocol).
The ‘PokerAgent’ botnet, which we have tracked in 2012, was designed to harvest Facebook log-on credentials, also collecting information on credit card details linked to the Facebook account and Zynga Poker player stats, presumably with the intention to mug the victims.
If you recently acquired an Apple Mac computer there are several simple steps you can take to protect your new machine, and all of the valuable information you will be storing on it.
In his summary of New Year predictions by security researchers here at ESET, Stephen Cobb pointed to expanded efforts by malware authors to target the Linux operating system. Looks like that might be right: A blog post published by Sucuri yesterday describes a backdoored version of the SSH daemon discovered on compromised servers. Interestingly, this
Malware authors have a solid track record in regards to creative Command and Control protocols. We’ve seen peer-to-peer protocols, some custom (Sality), some standard (Win32/Storm uses the eDonkey P2P protocol). We’ve seen binary protocols (Win32/Peerfrag, aka Palevo). We’ve seen other custom protocols that leverage other standard protocols such as HTTP (Win32/Georbot), DNS (Morto)and IRC (Win32/AutoRun.IRCBot.AK),
As we read earlier this week, the chances that one or more of your digital devices may get stolen are uncomfortably high. So what would happen if your mobile device falls into the wrong hands? Here are a few tips that will help minimize the damage if it happens to you.
Everybody knows that laptop computers, tablets and smartphones get stolen, and everybody reading this probably owns at least one of these digital devices, so should you be concerned about yours being pinched, pilfered, peculated, purloined, or in other words, stolen?
[Update 2: a note for Mac users in Turn off that Java Lamp. And Brian Krebs notes that Oracle Ships Critical Security Update for Java] [Update to a link at java.com offering more information on disabling Java in web browsers.] This is a quick pointer to blogs posted by our colleagues in Spain and in
The infamous exploit packs Blackhole and Nuclear Pack now feature a new zero-day Java exploit that exploits the Java vulnerability CVE-2013-0422. The latest version of Java 7 Update 10 is affected. Malware spreading through drive-by-downloads often utilizes exploit packs, which are able to serve malware variants without any user interaction, as opposed to other techniques
Apparently we posted 235 blogs here in 2012, just a fraction under 20 blogs per month on average. So this would be a perfect moment to produce one of those summaries of the year’s activities that wordpress.com provides, telling you how many people viewed your blog site and how many times they’d go round the
