About ransomware, Google malvertising and Fraud

I am sick and tired to see so many people affected by this wave of ransomware attacks. I don’t want to go into details about Ransomware like Locky because it has been written quite a lot about it. The most common way that Locky arrives is as follows: You receive an email containing an attached document. The document advises you to enable macros “if the data encoding is incorrect.” If you enable macros, you don’t actually correct the text encoding (that’s a subterfuge); instead, you run code inside the document that saves a file to disk and runs it. The…


Digital blackmailing

We are used to see ransomware encrypting files and requesting money (bitcoin) to decrypt them. I received now a new email on a corporate address, which is a black-e-mail … in digital form. I have to say, that the amount of thoughts expressed in the email is interesting. Somebody, with some basic knowledge and bad English knowledge has put some infos together. 🙂   Here is the plain text, so that it is easier to index: Hello. I do not want to judge anyone, but as a result of several occasions, we have point of contact from now. I do…


Annoying Internet Ads: An Open Letter To Digital Marketers Everywhere

I gave a nice interview to MICHAEL O’DWYER for IPSwitch and he wrote the following article: Annoying Internet Ads: An Open Letter To Digital Marketers Everywhere “Ads consume bandwidth, especially those delivered as Flash or code. If you’re on a mobile device, with a small screen, the ads will also cover a good portion of the screen, thus making it difficult or even impossible to see the desired content you want to see,” says Sorin Mustaca, CSSLP, Security+, Project+, an independent IT security consultant. “[Over] the last 3 years, we hear[d] more and more about malvertising — the delivery of malicious software…


Social engineering at its best: ransomware delivery methods

I wrote already about Ransomware (and here), but in a more generic way as I will do now. From me to me, with the subject “Documents from work” is the subject of a new Locky ransomware. Attached is a Word document containing macros. In the document (which is actually an archive) is a file called  word\vbaProject.bin. That file seems to be the trigger that downloads the ransomware binary.   This is the link to the VirusTotal detection: https://virustotal.com/en/file/28ba8362af69958964bf8d7e23664cddc625e67b55ff5d5e95e9feef74158e96/analysis/1469020147/ At the moment of writing this post, 30/53 engine detect it.   My goal is not to analyze here the ransomware, but the delivery….

IT Security essentials for small and medium enterprises

Since I first published the free eBook "Improve your security" dedicated to end users, I've been asked many times to give advises for small and medium enterprises. At first, I thought that this is a very different topic than what I wrote before. However, after some thinking, I realized, that difference between the behavior of end-users at home and in the office of a small to medium companies, doesn't differ that much. After all, it is no secret that the cyber criminals are where the money are. If the targets are easy to breach, it is even better since this improves the…
