AutoIT3[1] is a powerful language that helps to built nice applications for Windows environments, mainly to automate tasks. If it looks pretty old, the latest version was released last September and it remains popular amongst developers, for the good… or the bad! Malware written in AutoIt3 has existed since the late 2000s, when attackers realized that the language was easy to learn (close to basic) but can also compiled into standalone PE files! From a malware point of view, such executables make an extended use of packed data, making them more stealthy.

Currently, in order to provide basic DDoS protection and filter aggressive bots, some form of Content Delivery Network (CDN) is usually the simplest and most cost-effective way to protect a web application. In a typical setup, DNS is used to point clients to the CDN, and the CDN will then forward the request to the actual web server. There are a number of companies offering services like this, and cloud providers will usually have solutions like this as well.

We continue to encounter high-profile vulnerabilities that relate to how URL mapping (or "aliases") interac|zsh:1: parse error near `&' ts with URL-based access control. Last week, we wrote about the Oracle Identity Manager vulnerability. I noticed some scans for an older vulnerability with similar roots today:

From time to time, it can be instructive to look at generic phishing messages that are delivered to one’s inbox or that are caught by basic spam filters. Although one usually doesn’t find much of interest, sometimes these little excursions into what should be a run-of-the-mill collection of basic, commonly used phishing techniques can lead one to find something new and unusual. This was the case with one of the messages delivered to our handler inbox yesterday…

When people discuss the security implications of Unicode, International Domain Names (IDNs) are often highlighted as a risk. However, while visible and often talked about, IDNs are probably not what you should really worry about when it comes to Unicode. There are several issues that impact application security beyond confusing domain names.

The finger.exe command is used in ClickFix attacks.

Today's Microsoft Patch Tuesday offers fixes for 80 different vulnerabilities. One of the vulnerabilities is already being exploited, and five are rated as critical.

XWiki describes itself as "The Advanced Open-Source Enterprise Wiki" and considers itself an alternative to Confluence and MediaWiki. In February, XWiki released an advisory (and patch) for an arbitrary remote code execution vulnerability. Affected was the SolrSearch component, which any user, even with minimal "Guest" privileges, can use. The advisory included PoC code, so it is a bit odd that it took so long for the vulnerability to be widely exploited.

Sensors reporting firewall logs detected a significant increase in scans for port 8530/TCP and 8531/TCP over the course of last week. Some of these reports originate from Shadowserver, and likely other researchers, but there are also some that do not correspond to known research-related IP addresses.
