The Rise of Super-Stealthy Digitally Signed Malware—Thanks to the Dark Web

The Rise of Super-Stealthy Digitally Signed Malware—Thanks to the Dark Web

Nov 06, 2017
Guess what's more expensive than counterfeit United States passports, stolen credit cards and even guns on the dark web? It's digital code signing certificates. A recent study conducted by the Cyber Security Research Institute (CSRI) this week revealed that stolen digital code-signing certificates are readily available for anyone to purchase on the dark web for up to $1,200. As you may know, digital certificates issued by a trusted certificate authority (CA) are used to cryptographically sign computer applications and software, and are trusted by your computer for execution of those programs without any warning messages. However, malware author and hackers who are always in search of advanced techniques to bypass security solutions have been abusing trusted digital certificates during recent years. Hackers use compromised code signing certificates associated with trusted software vendors in order to sign their malicious code, reducing the possibility of their malw

Detecting Windows-based Malware Through Better Visibility

Apr 01, 2024 Malware Detection / Endpoint Security
Despite a plethora of available security solutions, more and more organizations fall victim to Ransomware and other threats. These continued threats aren't just an inconvenience that hurt businesses and end users - they damage the economy, endanger lives, destroy businesses and put national security at risk. But if that wasn't enough – North Korea appears to be  using revenue from cyber attacks to funds its nuclear weapons program . Small and mid-size businesses are increasingly caught in the dragnet of ongoing malware attacks - often due to underfunded IT departments. Exacerbating the problem are complex enterprise security solutions that are often out of reach for many companies - especially when multiple products are seemingly needed to establish a solid defense. Volume-based products that incentivize users to collect less data in order to conserve funds work backward, dampening the anticipated benefits. But what if you could detect many malware attacks holistically with
Dangerous Malware Discovered that Can Take Down Electric Power Grids

Dangerous Malware Discovered that Can Take Down Electric Power Grids

Jun 12, 2017
Last December, a cyber attack on Ukrainian Electric power grid caused the power outage in the northern part of Kiev — the country's capital — and surrounding areas, causing a blackout for tens of thousands of citizens for an hour and fifteen minutes around midnight. Now, security researchers have discovered the culprit behind those cyber attacks on the Ukrainian industrial control systems. Slovakia-based security software maker ESET and US critical infrastructure security firm Dragos Inc. say they have discovered a new dangerous piece of malware in the wild that targets critical industrial control systems and is capable of causing blackouts. Dubbed " Industroyer " or " CrashOverRide ," the grid-sabotaging malware was likely to be used in the December 2016 cyber attack against Ukrainian electric utility Ukrenergo , which the security firms say represents a dangerous advancement in critical infrastructure hacking. According to the researchers, CrashO

SHQ Response Platform and Risk Centre to Enable Management and Analysts Alike

May 13, 2024Threat Detection / SoC / SIEM
In the last decade, there has been a growing disconnect between front-line analysts and senior management in IT and Cybersecurity. Well-documented challenges facing modern analysts revolve around a high volume of alerts, false positives, poor visibility of technical environments, and analysts spending too much time on manual tasks. The Impact of Alert Fatigue and False Positives  Analysts are overwhelmed with alerts. The knock-on effect of this is that fatigued analysts are at risk of missing key details in incidents, and often conduct time-consuming triaging tasks manually only to end up copying and pasting a generic closing comment into a false positive alert.  It is likely that there will always be false positives. And many would argue that a false positive is better than a false negative. But for proactive actions to be made, we must move closer to the heart of an incident. That requires diving into how analysts conduct the triage and investigation process. SHQ Response Platfo

MALWARE WORKS AFTER SWITCHING OFF MOBILES When users presses the power button on their device, a fake dialog box is shown. The malware mimics the shutdown animation and the device appears to be off, but actually remains on, giving the malicious program freedom to move around on the device and steal data. "After pressing the power button, you will see the real shutdown animation, and the phone appears off. Although the screen is bl
How to Build a Custom Malware Analysis Sandbox

How to Build a Custom Malware Analysis Sandbox

Mar 24, 2022
Before hunting malware, every researcher needs to find a system where to analyze it. There are several ways to do it: build your own environment or use third-party solutions. Today we will walk through all the steps of creating a custom malware sandbox where you can perform a proper analysis without infecting your computer. And then compare it with a ready-made service. Why do you need a malware sandbox?  A sandbox allows detecting cyber threats and analyzing them safely. All information remains secure, and a suspicious file can't access the system. You can monitor malware processes, identify their patterns and investigate behavior. Before setting up a sandbox, you should have a clear goal of what you want to achieve through the lab.  There are two ways how to organize your working space for analysis: Custom sandbox.  Made from scratch by an analyst on their own, specifically for their needs. A turnkey solution.  A versatile service with a range of configurations to meet yo

Evolution of Emotet: From Banking Trojan to Malware Distributor

Nov 19, 2020
Emotet is one of the most dangerous and widespread malware threats active today. Ever since its discovery in 2014—when Emotet was a standard credential stealer and banking Trojan, the malware has evolved into a modular, polymorphic platform for distributing other kinds of computer viruses. Being constantly under development, Emotet updates itself regularly to improve stealthiness, persistence, and add new spying capabilities. This notorious Trojan is one of the most frequently malicious programs found in the wild. Usually, it is a part of a phishing attack, email spam that infects PCs with malware and spreads among other computers in the network. If you'd like to find out more about the malware, collect IOCs, and get fresh samples, check the following article in the Malware trends tracker , the service with dynamic articles.
