Magnitude Exploit Kit Now Targeting South Korea With Magniber Ransomware

A new ransomware is being distributed by the Magnitude exploit kit: Magniber (detected by Trend Micro as RANSOM_MAGNIBER.A), which we found targeting South Korea via malvertisements on attacker-owned domains/sites. The development in Magnitude’s activity is notable not only because it eschewed Cerber—its usual ransomware payload—in favor of Magniber. Magnitude now also appears to have become an exploit kit expressly targeting South Korean end users.

The Magnitude exploit kit, which previously had a global reach, was offered as a service in the cybercriminal underground as early as 2013. It then left the market and became a private exploit kit that mainly distributed ransomware such as CryptoWall. At the start of the second half of 2016, Magnitude shifted focus to Asian countries, delivering various ransomware such as Locky and Cerber. More recently though, we noticed that Magnitude underwent a hiatus that began on September 23, 2017, and it then returned on October 15. With help from Kafeine and malc0de, we were able to uncover Magnitude’s new payload, Magniber.

Cerber Ransomware Evolves Again, Now Steals From Bitcoin Wallets

Cerber ransomware has acquired the reputation of being one of the most rapidly evolving ransomware families to date. Just in May, we pointed out how it had gone through six separate versions with various differences in its routines. Several months later and it seems to have evolved again, this time adding cryptocurrency theft to its routines. This is on top of its normal ransomware routines, giving the attackers two ways to profit off of one infection.

Cerber Version 6 Shows How Far the Ransomware Has Come (and How Far it’ll Go)

Cerber set itself apart from other file-encrypting malware when its developers commoditized the malware, adopting a business model where fellow cybercriminals can buy the ransomware as a service. The developers earn through commissions—as much as 40%—for every ransom paid by the victim. Coupled with persistence, Cerber turned into a cybercriminal goldmine that reportedly earned its developers $200,000 in commissions in a month alone last year.

Being lucrative and customizable for affiliates, it’s no wonder that Cerber spawned various iterations. Our coverage of unique Cerber samples—based on feedback from Smart Protection Network™—shows enterprises and individual users alike are taking the brunt, with the U.S. accounting for much of Cerber’s impact. We’ve also observed Cerber’s adverse impact among organizations in education, manufacturing, public sector, technology, healthcare, energy, and transportation industries.

A reflection of how far Cerber has come in the threat landscape—and how far it’ll go—is Cerber Version 6, the ransomware’s latest version we’ve uncovered and monitored since early April this year. It sports multipart arrival vectors and refashioned file encryption routines, along with defense mechanisms that include anti-sandbox and anti-AV techniques.

Cerber Starts Evading Machine Learning

CERBER is a ransomware family which has adopted a new technique to make itself harder to detect: it is now using a new loader which appears to be designed to evade detection by machine learning solutions. This loader is designed to hollow out a normal process where the code of CERBER is instead run.

CERBER Changes Course, Triple Checks for Security Software

CERBER is a ransomware family that has seen its share of unusual features since its appearance early last year. From its use of audio warnings, to the targeting of cloud platforms and databases, to distribution via malvertising, emailed scripting files, and exploit kits, CERBER has always been willing to keep up with the times, as it was. One reason for its apparent popularity may be the fact that it is sold in the Russian underground, giving a wide variety of cybercriminals access to it.

However, we’ve started seeing CERBER variants (which we detect as RANSOM_CERBER.F117AK) add a new wrinkle to their behavior: they have gone out of their way to avoid encrypting security software. How did they do this?

Security Predictions for 2020

  • Cybersecurity in 2020 will be viewed through many lenses — from differing attacker motivations and cybercriminal arsenal to technological developments and global threat intelligence — only so defenders can keep up with the broad range of threats.

Business Process Compromise

  • Attackers are starting to invest in long-term operations that target specific processes enterprises rely on. They scout for vulnerable practices, susceptible systems and operational loopholes that they can leverage or abuse. To learn more, read our Security 101: Business Process Compromise.
