June’s Most Wanted Malware: Banking Trojans Up 50% Among Threat Actors

Check Point’s latest Global Threat Index reveals that Trojan malware families enter Top 10 Most Wanted Ranking; Cryptomining Remains Tops on List

Over the past four months, banking Trojans have increased their global impact by 50 percent, as two Trojan malware families enter the latest Global Threat Index’s Top 10 Most Wanted Malware.

In June 2018, Dorkbot, a banking Trojan that steals sensitive information and launches denial-of-service attacks, affected 7 percent of all organizations across the world, moving up from No. 8 to No. 3 in Check Point’s Most Wanted Malware list. This past month also saw the emergence of Emotet, a banking Trojan that steals victims’ bank account credentials while using the infected machine in order to spread. The Emotet variant has risen rapidly in prevalence over the past two months, moving from 50th in April’s Index in April, to 11th in the latest index. Along with Dorkbot, the Ramnit Trojan – which steals banking credentials and FTP passwords – also entered the Top 10.

Check Point’s researchers observed a similar aggressive attack pattern of cyber-criminals utilizing banking Trojans during the summer of 2017. This suggests that cyber-criminals are perhaps attempting to capitalize on tourists paying less attention to cyber-security best practices while on vacation, potentially accessing online banking across shared access devices and less secure connections such as public WiFi hotspots.

To prevent their networks being exploited by banking trojans – and other types of attack – it is critical that enterprises employ a multi-layered cybersecurity strategy that protects against both established malware families cyber-attacks and brand new threats.

June’s 2018’s Top 10 ‘Most Wanted’:

*The arrows relate to the change in rank compared to the previous month.

1. ↔ Coinhive – Cryptominer designed to perform online mining of Monero cryptocurrency when a user visits a web page without the user’s knowledge or approval the profits with the user. The implanted JavaScript uses a great deal of the computational resources of end users’ machines to mine coins, and may crash the system.
2. ↔ Cryptoloot – Cryptominer, using the victim’s CPU or GPU power and existing resources for crypto mining – adding transactions to the blockchain and releasing new currency. It is a competitor to Coinhive, trying to pull the rug under it by asking a smaller percentage of revenue from websites.
3. ↑Dorkbot- IRC-based Worm designed to allow remote code execution by its operator, as well as the download of additional malware to the infected system. It is a banking Trojan, with the primary motivation being to steal sensitive information and launch denial-of-service attacks.
4. ↑ Andromeda – Modular bot used mainly as a backdoor to deliver additional malware on infected hosts, but can be modified to create different types of botnets.
5. ↓ Roughted – Large scale Malvertising used to deliver various malicious websites and payloads such as scams, adware, exploit kits and ransomware. It can be used to attack any type of platform and operating system, and utilizes ad-blocker bypassing and fingerprinting in order to make sure it delivers the most relevant attack.
6. ↓ JSEcoin – JavaScript miner that can be embedded in websites. With JSEcoin, you can run the miner directly in your browser in exchange for an ad-free experience, in-game currency and other incentives
7. ↔ XMRig– XMRig is an open-source CPU mining software used for the mining process of the Monero cryptocurrency, and first seen in-the-wild on May 2017.
8. ↑ Nivdort- Multipurpose bot, also known as Bayrob, that is used to collect passwords, modify system settings and download additional malware. It is usually spread via spam emails with the recipient address encoded in the binary, thus making each file unique.
9. ↓ Fireball – Browser-hijacker that can be turned into a full-functioning malware downloader. It is capable of executing any code on the victim machines, resulting in a wide range of actions from stealing credentials to dropping additional malware.
10. ↑ Ramnit– Banking Trojan that steals banking credentials, FTP passwords, session cookies and personal data.

Triada, a modular backdoor for Android which grants super user privileges, was the most popular malware used to attack organizations’ mobile estates followed by the Lokibot and The Truth Spy.

June’s Top 3 ‘Most Wanted’ mobile malware:

1. Triada – Modular Backdoor for Android which grants super user privileges to downloaded malware, as helps it to get embedded into system processes. Triada has also been seen spoofing URLs loaded in the browser.
2.  Lokibot – Android banking Trojan and info-stealer, which can also turn into a ransomware that locks the phone in case its admin privileges are removed.
3. The Truth Spy– Spyware for Apple and Android phones enable to track all kinds of activities going on the phone, including monitoring of WhatsApp messages, Facebook chats, and internet browsing history.

Check Point researchers also analyzed the most exploited cyber vulnerabilities. In first was CVE-2017-7269, with a global impact of 40%, followed by CVE-2017-10271 affecting 35% of organizations worldwide. In third place was SQL injection impacting 15% organizations globally.

June’s Top 3 ‘Most Wanted’ vulnerabilities:

1. ↔ Microsoft IIS WebDAV ScStoragePathFromUrl Buffer Overflow (CVE-2017-7269) – By sending a crafted request over a network to Microsoft Windows Server 2003 R2 through Microsoft Internet Information Services 6.0, a remote attacker could execute arbitrary code or cause a denial of service conditions on the target server. That is mainly due to a buffer overflow vulnerability resulted by improper validation of a long header in HTTP request. A patch has been available since March 2017.
2. ↔ Oracle WebLogic WLS Security Component Remote Code Execution (CVE-2017-10271) – A remote code execution vulnerability exists within Oracle WebLogic WLS. This is due to the way Oracle WebLogic handles xml decodes. A successful attack could lead to a remote code execution. A patch has been available since October 2017.
3. ↔ SQL Injection – Inserting an injection of SQL query in input from client to application, while exploiting a security vulnerability in an application’s software.

This list perfectly demonstrates how threat actors use both modern techniques (two vulnerabilities published in 2017) and classic attack vectors such as SQL injection.

The map below displays the risk index globally (green – low risk, red- high risk, grey – insufficient data), demonstrating the main risk areas and malware hot-spots around the world.

Check Point’s Global Threat Impact Index and its ThreatCloud Map is powered by Check Point’s ThreatCloud intelligence, the largest collaborative network to fight cybercrime which delivers threat data and attack trends from a global network of threat sensors. The ThreatCloud database holds over 250 million addresses analyzed for bot discovery, more than 11 million malware signatures and over 5.5 million infected websites, and identifies millions of malware types daily.
