Nexus Mods site goes public with “bad ad” report

We cover a lot of Malvertising disasters on this blog, and I’ve previously looked at how many websites will go to war with a user’s ad blockers – or indeed, try to disavow themselves of any harm done through infection (“It wasn’t us, it was the ad provider!”) Today, we have an example of a high traffic website so fed up wi

Malvertising Campaign via Pop-under Ads Sends CryptoWall 4

We have caught a new malvertising campaign on the PopAds network launching the Magnitude exploit kit via pop-under ads. A pop-under is an ad window that appears behind the main browser window and typically remains open until the user manually closes it. Unsuspecting victims running outdated versions of the Flash Player were immediately infected with the Cryp

Clickjacking Campaign Plays on European Cookie Law

We’ve spotted an advertising campaign that tricks users into clicking on what looks like a notification alert that actually hides a legitimate advert, therefore abusing both the advertiser and the ad network hosting the ad (Google Ads Services). The rogue actors behind this fraudulent activity are cleverly leveraging a European law on the use of cookie

Large Number of Adult Sites Distribute Malware Via AdXpansion Malvertising

While malvertising activity on adult sites has been ‘relatively’ quiet for some time, we started picking up dozens of attacks on moderately popular XXX portals, where moderate still means millions of daily visitors. The modus operandi is quite straightforward and facilitated by a compromised Flash advert directly hosted and served by AdXpansion,

Advertising – to block or not to block? (Poll)

I have become pretty immune to advertising on the net. The brain develops an algorithm to locate the relevant content and filter out the junk around it. Frankly speaking, ask me about what ads there were on the page I just visited, and I have no clue. And I believe that’s true for many of us. Except that our internal ad-blockers aren’t perfect. The advertisi

Forget the personality tests – Ask Facebook instead (Poll)

It’s amazing how advertising can power huge companies. Google has over 57 000 employees and some 66 billion US dollars in revenue. And Facebook with 12 billion and 10 000 employees. These two giants are the best know providers of ad-financed services on the net. And modern advertising is targeted, which means that they must know what the users want to see. W

Introduction to Alternate Data Streams

What are Alternate Data Streams? Alternate Data Streams (ADS) are a file attribute only found on the NTFS file system. In this system a file is built up from a couple of attributes, one of them is $Data, aka the data attribute. Looking at the regular data stream of a text file there is no mystery.

Advertising: The Digital Turf War on your Desktop

Hello! Here’s your computer after ten minutes on the Internet: This nightmarish vision of “Buy all the things” is a very old screenshot of mine from many years ago, when ads were in full swing, Adware vendors were happy to cover your screen in wall-to-wall pop ups and ad blockers were still running around in diapers.

POLL – How should we deal with harmful license terms?

We blogged last week, once again, about the fact that people fail to read the license terms they approve when installing software. That post was inspired by a Chrome extension that monetized by collecting and selling data about users’ surfing behavior. People found out about this, got mad and called it spyware. Even if the data collection was documented in t
