While it does not boast any special or complex installation tactics, Shlayer’s distribution vector has made it a tremendous success - the malware has been the most prevalent MacOS strain since its debut two years ago, never falling off its leading spot. Shlayer uses a well-known infection tactic – pressing on a bad link directs the victim to a fake Adobe Flash update.Read More
The chief problem with cyber security is that most of our tools and workforce is geared to waiting for adverse events, detecting those events (sometimes months after the fact), investigating the breach that has already occurred, and then cleaning up. This slow and reactive process ensures breaches happen and security staff us overwhelmed under the noise.
This talk will focus on automation and machine learning techniques that can proactively identify threats seen in the wild based on the latest academic research. This techniques allow organizations to identify suspect infrastructure before it is used to attack them. The key to making this work is infusing machine learning with knowledge of how actual attacks work and the threat landscape. Machine learning without intelligence is merely gussied up mensa math exercises.
Earlier this month, a new variant of the Guildma information stealer was analyzed by the Internet Storm Center (ISC). The malware’s new campaign has been seen targeting various countries in South America, with the highest number of infections recorded in Brazil. It seems that Guildma is spreading quickly, with another recent campaign reaching over 150,000 infection attempts in a matter of weeks.Read More
Making connections and finding new indicators is an important part of IOC analysis, and is probably the most enjoyable part as well. Blog posts and reports on new threats will usually mention the indicators seen to be used by the specific malware sample or attack vector analyzed, yet in many cases there is a larger malicious infrastructure behind them just waiting to be uncovered (and blocked!). Sometimes, a whole other malicious infrastructure can be revealed by examining IOCs related to malicious IPs and domains. There are a variety of tools out there that can help analysts investigate indicators of compromise and their infrastructure, and perform enrichment to shed light on related, malicious IOCs.
In this post, we will review some of our Security Research Team’s favorite connection and enrichment platforms.
Welcome To Our New Weekly Series, Free Open Source Analysis Tools.
This Week's Topic: Free Open-Source Analysis Tools, Why Use IOCs?
Throughout this series, we'll be talking about a Security Analyst’s IOC analysis journey. From discovering relevant indicators and performing the analysis, to finding enrichments and new IOCs. We will also share recommendations for free open-source analysis tools and use cases completed by ThreatSTOP's Security and Research Team, showing how to utilize the various platforms and tools. Let's get started.Read More
You’ve probably heard of Threat Intelligence, it's all the rage and all the cool kids are doing it… where’ve you been? Threat Intelligence, or “TI,” is everywhere and in everything, and it can be cool, but it can also be slippery and confusing and complex and a huge waste of time and resources depending on what you do (or don’t do) with it. In this post, we’re going to make a bunch of snarky statements about Threat Intelligence, and we’re going to spill the tea on how you (as a small or medium sized business) can use it and actually get some security value in return.Read More
A few months ago, JasperLoader (a new malware loader) emerged, infecting systems with various malware payloads, such as the Gootkit Banking Trojan. After a short, initial campaign, the threat actors behind the malware halted their activity and JasperLoader went off the radar for a while. However, since late May, a new and upgraded version of JasperLoader has been spotted infecting machines across Europe.Read More
In the past, a green padlock icon would inform the user that a site is secure and legit, whether it was true or false. Now, that is no longer the case. We are seeing more and more phishing sites using SSL/TLS certificates to try and fool people into thinking that a phishing site is actually legitimate. The appearance of free SSL/TLS certificates, which can be applied with ease (Let’s Encrypt, Comodo and more), allow scammers to harness SSL certificates to their own agenda, giving misguided people the felling of false security.Read More
DNS is one of the single biggest important components to making the global internet work and it is often the most neglected aspects of a network. Invented in the 80's, DNS “just works," but its ease of use has people overlooking the power of using it to protect their customers. DNS offers the first clues to what is going on in your network and is used by criminals to steal data.Read More
As part of BrightTALK's 2019 Trends and Predictions Webcast series, ThreatSTOP's VP of Security and Research, John Bambenek, is talking specifically about social engineering and phishing on this December 13th episode. Check out the details here:Read More
