Virobot Ransomware with Botnet Capability Breaks Through

We’ve predicted that ransomware attacks will plateau in 2017 but will diversify in terms of attack methods as time progresses. Ransomware activity in the first half of 2018 proved this to be true, with more innovative methods to raise the ante. Case in point: we have recently observed Virobot (detected by Trend Micro as RANSOM_VIBOROT.THIAHAH), with both ransomware and botnet capabilities, affecting users in the United States. Once Viborot infects a machine, it also becomes part of a spam email botnet that distributes the ransomware to more victims. Virobot is not associated with any known ransomware families.

Infection Chain

Virobot was first observed in the wild on September 17, 2018, seven days after we analyzed a ransomware variant that imitates the notorious Locky ransomware. Once Virobot is downloaded to a machine, it will check the presence of registry keys (machine GUID and product key) to determine if the system should be encrypted.

REGISTRY KEYS_VIROBOT RANSOMWARE

Figure 1. Virobot queries the machine to see if contains the registry keys needed for encryption.

The ransomware then generates an encryption and decryption key via a cryptographic Random Number Generator. Together with the generated key, Virobot will then send the machine-gathered data to its C&C server via POST.

Virobot will start its encryption process. The following files are encrypted via RSA encryption:

ENCRYPTED FILES_VIROBOT RANSOMWARE

Figure 2. Code snippet showing the ransomware’s encryption

After encryption, it will display a ransom note and ransom screen. Interestingly, despite finding that the ransomware affects users in the US as of writing time, the ransom note was written in French:

VIBOROT RANSOM SCREEN

RANSOM NOTE_VIBOROT RANSOMWARE

Figures 3 and 4. Screen captures of Virobot’s ransom screen (top) and ransom note (bottom). Written in French, it states “Vos fichiers personnels ont été chiffré,” which translates to “Your personal files have been encrypted.”

Virobot also has a keylogging feature, and connects back to its C&C server to send logged key strokes from an infected machine. Once connected to the C&C, it may download files – possibly another malware binary – and execute it using PowerShell.

KEYLOGGER_VIROBOT RANSOMWARE

Figure 5. Code snippet showcasing Virobot’s keylogging capability.

Virobot’s botnet capability is evidenced by its use of an infected machine’s Microsoft Outlook to send spam emails to the user’s contact list. Virobot will send a copy of itself or a malicious file downloaded from its C&C server.

Figures 6 and 7. Code snippets featuring Virobot’s propagation routine using Microsoft Outlook.

The ransomware needs to establish communication to its C&C server to successfully encrypt files. However, as of writing time, it is no longer able to encrypt files because Virobot’s C&C was taken down.

Trend Micro Ransomware Solutions

Individuals and enterprises should use a multi-layered approach to mitigate the risks brought by threats like ransomware.

Email and web gateway solutions such as Trend Micro™ Deep Discovery™ Email Inspector and InterScan™ Web Security can prevent ransomware from ever reaching end users. At the endpoint level, Trend Micro Smart Protection Suites deliver several capabilities like high fidelity machine learning, behavior monitoring and application control, and vulnerability shielding that minimizes the impact of this threat. Trend Micro Deep Discovery Inspector detects and blocks ransomware on networks, while Trend Micro Deep Security™ stops ransomware from reaching enterprise servers–regardless if they’re physical, virtual, or in the cloud.

For small businesses, Trend Micro Worry-Free Services Advanced offers cloud-based email gateway security through Hosted Email Security. Its endpoint protection also delivers several capabilities such as behavior monitoring and real-time web reputation in order detect and block ransomware.

For home users, Trend Micro Security 10 provides strong protection against ransomware by blocking malicious websites, emails, and files associated with this threat.

Trend Micro Crypto-Ransomware File Decryptor Tool can decrypt files affected by certain crypto-ransomware variants without having to pay the ransom in exchange for the decryption key.

Tailored to the increasingly connected world we live in, our evolved line of products focuses on better performance, better ransomware protection, and a holistic approach to securing every facet of a connected consumer’s life. Curious how exactly our lineup does that? Allow us to break it down.

First, there are a few key product updates. In exciting news, McAfee Identity Theft Protection and McAfee Safe Family are now both included in McAfee Total Protection and McAfee LiveSafe. Additionally, McAfee Ransom Guard and PC Boost have been added to the entire product lineup, which includes McAfee AntiVirus, McAfee AntiVirus Plus and McAfee Internet Security. Now, let’s get into a few specifics about product performance.

Improved Performance

McAfee’s core lineup of products now sends malware analysis to the McAfee Global Threat Intelligence (GTI) cloud, which means fewer system resources are required, and PCs can work at optimal speeds. Beyond that, we’ve also implemented a few key PC enhancements, including:

There’s a few notable mobile enhancements as well, which include:

Increased Ransomware Protection

Ransomware attacks have shown no signs of slowing, which is why last year McAfee introduced a machine learning-based anti-virus engine with Real Protect to protect consumers from modern-day threats. And now we’ve updated our features to continue the fight against these advanced attacks. New features include:

Protecting People’s Digital Lives

As people become more and more connected in the modern digital era, they’re in need of protection in every part of their online life. That’s why McAfee’s new lineup now includes features that make it easier than ever to protect what matters most. This includes:

So, whether you’re focused on fighting back against ransomware, or ensuring all your online interactions are protected from threats, our evolved portfolio of products is here to ensure you can live your connected life with confidence. Make sure you get proactive about your personal protection now.

Equifax breach could be most costly in corporate history

NEW YORK/TORONTO (Reuters) – Equifax Inc (EFX.N) said it expects costs related to its massive 2017 data breach to surge by $275 million this year, suggesting the incident at the credit reporting bureau could turn out to be the most costly hack in corporate history.

The projection, which was disclosed on a Friday morning earnings conference call, is on top of $164 million in pretax costs posted in the second half of 2017. That brings expected breach-related costs through the end of this year to $439 million, some $125 million of which Equifax said will be covered by insurance.

“It looks like this will be the most expensive data breach in history,” said Larry Ponemon, chairman of Ponemon Institute, a research group that tracks costs of cyber attacks.

Total costs of the breach, which compromised sensitive data of some 247 million consumers, could be“well over $600 million,” after including costs to resolve government investigations into the incident and civil lawsuits against the firm, he said.

The post Equifax breach could be most costly in corporate history appeared first on CyberESI.
