Insights Into Proactive Threat Hunting

Reading time4 min
Views945

Proactive search for complex threats seems to be a useful technology but inaccessible for many organizations. Is it really so? What do companies need to do to start Threat Hunting? What tools are needed for threat hunting? What trends in this area can be seen on the market in the coming years? These are some of the questions I would like to answer in my article today.

What is Threat Hunting?

Threat Hunting is a search for threats in a proactive mode when the information security specialist is sure that the network is compromised. He should understand how his network operates in order to be able to identify various attacks by examining the existing anomalies.

Threat Hunting is a search for threats that have already bypassed automated detection systems. Moreover, most often, you do not have signals or alerts that allow you to detect an intrusion.

From the SOC perspective, Threat Hunting is an extension of the service that allows you to counter any level of intruders, including those who use previously unknown tools and methods.

Threat Hunting can be based on some data obtained by a security specialist, or it can be based on a hypothesis. If after testing the hypothesis, the test gives a positive result, then later, it can be used to improve the processes and mechanisms of detecting threats. And also, Threat Hunting allows you to find blind spots in the security system and expand the monitoring area.

What organizations need Threat Hunting?

Proactive threat hunting is relevant to those organizations that can become the target of a complex, targeted APT attack. At the same time, given the trend towards supply chain attacks, a small company may also become a target for motivated attackers.

MISRA C: struggle for code quality and security

Reading time11 min
Views1.2K

A couple of years ago the PVS-Studio analyzer got its first diagnostic rules to check program code compliance with the MISRA C and MISRA C++ standards. We collected feedback and saw that our clients were interested in using the analyzer to check their projects for MISRA compliance. So, we decided to further develop the analyzer in this direction. The article covers the MISRA C/C++ standard and the MISRA Compliance report. It also shows what we already managed to do and what we plan to achieve by the end of the year.

Video recording of a closed session of the upper house of Russia's parliament was leaked online by Telegram channel A000MP97. In the video, Andrei Klimov, head of the Ad Hoc Sovereignty and Preventing Interference in the Domestic Affairs Commission, demands Apple to disclose who controls the App Store: people from Mars or artificial intelligence?

On September 16th, a closed session of the Commission took place, and representatives of Apple and Google were among those who were invited. The session discussed ways to protect sovereignty of the country, in particular, the fact that the Navalny app was still available in Apple App Store and Google Play. The services were accused of being complicit with organisations deemed extremist and banned in Russia as well as interference with Russian elections.

Hi from RaccoonLab, a team of enthusiasts in field robotics! We want to share our true-HITL UAVCAN-based simulator for PX4.

We believe a unified UAVCAN bus for drone onboard electronics will become a mainstream approach shortly. Our simulator is already based on UAVCAN (in opposition to UART-MAVLINK) and emulates exactly the same messages as real UAVCAN-sensors.

Comparing Huawei ExaGear to Apple's Rosetta 2 and Microsoft's solution

Reading time7 min
Views3.7K

November 10, 2020 was in many ways a landmark event in the microprocessor industry: Apple unveiled its new Mac Mini, the main feature of which was the new M1 chip, developed in-house. It is not an exaggeration to say that this processor is a landmark achievement for the ARM ecosystem: finally an ARM architecture chip whose performance surpassed x86 architecture chips from competitors such as Intel, a niche that had been dominated for decades.

But the main interest for us is not the M1 processor itself, but the Rosetta 2 binary translation technology. This allows the user to run legacy x86 software that has not been migrated to the ARM architecture. Apple has a lot of experience in developing binary translation solutions and is a recognized leader in this area. The first version of the Rosetta binary translator appeared in 2006 were it aided Apple in the transition from PowerPC to x86 architecture. Although this time platforms were different from those of 2006, it was obvious that all the experience that Apple engineers had accumulated over the years, was not lost, but used to develop the next version - Rosetta 2.

We were keen to compare this new solution from Apple, a similar product Huawei ExaGear (with its lineage from Eltechs ExaGear) developed by our team. At the same time, we evaluated the performance of binary translation from x86 to Arm provided by Microsoft (part of MS Windows 10 for Arm devices) on the Huawei MateBook E laptop. At present, these are the only other x86 to Arm binary translation solution that we are aware of on the open market.

Introduction

For the last five years, there have virtually been almost no global-scale application-layer attacks.

During this period, the industry has learned how to cope with the high bandwidth network layer attacks, including amplification-based ones. It does not mean that botnets are now harmless.

End of June 2021, Qrator Labs started to see signs of a new assaulting force on the Internet – a botnet of a new kind. That is a joint research we conducted together with Yandex to elaborate on the specifics of the DDoS attacks enabler emerging in almost real-time.

A note on small-signal modeling of SEPIC CM CCM

Reading time6 min
Views3.1K

Knowing parameters of small-signal control-to-output transfer functions makes it easier for engineers to design compensation networks of DC/DC converters. The equations for SEPIC can be found in different works and Application Notes, but there are differences. A work has been done to solve this problem.

Simplified design equations for SEPIC with Current Mode control (CM) in Continuous Conduction Mode (CCM) suitable for practical design of compensation networks are shown.

Business trips with a cat on my lap or how to diversify remote work life

Reading time6 min
Views1.2K

It has been a year since most of our life has become online. We at ISPsystem are used to working from the office and seeing all team members every day at arm's length. I adapted quickly to the new format. However, I will be honest; working remotely is not as easy as it may seem from the outside. Many fail to cope. The lack of live communication and the too familiar four walls make you not notice how the seasons change.

So how can one adapt to the situation? How to diversify your work, get new experiences and pump up your skills without leaving home? I want to share our experience with internal mission trips. It can be useful for companies that have several product teams at once.

In this article, I am going to look at Redis versus Tarantool. At a first glance, they are quite alike — in-memory, NoSQL, key value. But we are going to look deeper. My goal is to find meaningful similarities and differences, I am not going to claim that one is better than the other.

There are three main parts to my story:

  • We’ll find out what is an in-memory database, or IMDB. When and how are they better than disk solutions?
  • Then, we’ll consider their architecture. What about their efficiency, reliability, and scaling?
  • Then, we’ll delve into technical details. Data types, iterators, indexes, transactions, programming languages, replication, and connectors.

Feel free to scroll down to the most interesting part or even the summary comparison table at the very bottom and the article.

Do you remember how just a few years ago it was a disaster to lose a camera at the end of a vacation? All memorable pictures and videos then disappeared along with the lost device. Probably, this fact prompted the great minds to invent cloud storage, so that the safety of records no longer depends on the presence of the devices on which these records are made.
