An Analysis of Ransomware Encryption Speeds by Splunk SURGe

Did you know the median time for ransomware to encrypt nearly 100,000 files is 42 minutes and 52 seconds? This speed is likely beyond the capabilities of most organizations to respond effectively before encryption is complete. These findings are the result of research published by SURGe, Splunk’s strategic cybersecurity research team.

Cyber Compliance and Data Breach Notifications

Ransomware isn’t just an internal threat for your organization, it’s also a global crime, and data breach notifications are governed by various laws, policies, and agencies. Let’s go over some common cyber-compliance questions about ransomware, data breach notification and reporting, and the laws that cover cybercrime.

Threat Update DoubleZero Destructor

The Splunk Threat Research Team is actively monitoring the emergence of new threats in the cyber domain of ongoing geopolitical events. As we have shown previously in several releases, including HermeticWiper and CaddyWiper, actors in this campaign are deploying, updating, and modifying stealthier malicious payloads. On March 17th, 2022, the Ukraine CERT discovered a new malicious payload named DoubleZero Destructor (CERT-UA #4243).

Vidar Malware Launcher Concealed in Help File

Appending a malicious file to an unsuspecting file format is one of the tricks our adversaries use to evade detection. Recently, we came across an interesting email campaign employing this technique to deliver the info stealer Vidar malware. First, let’s examine the email delivery mechanism, then go on to take a closer look at the Vidar malware itself. Figure 1: The malicious spam message The messages in this campaign have two things in common.

AvosLocker ransomware - what you need to know

AvosLocker is a ransomware-as-a-service (RaaS) gang that first appeared in mid-2021. It has since become notorious for its attacks targeting critical infrastructure in the United States, including the sectors of financial services, critical manufacturing, and government facilities.

Gone in 52 Seconds...and 42 Minutes: A Comparative Analysis of Ransomware Encryption Speed

Do you feel like every other cybersecurity news story mentioned ransomware in 2021? Does it feel like you can’t turn on a cybersecurity podcast and not hear the “R” word? We feel the same way, and as a cybersecurity vendor, we felt that we should also contribute to the noise. :-) But we did want to try and do something different.

Choosing the Right Metadata Store: Part 1

Rubrik CDM is scale-out and fault-tolerant. Our software runs as a clustered system consisting of multiple nodes, where each node runs an identical copy of our software stack; each node is equally able to perform operations like data protection and recovery. To increase capacity a user simply adds more nodes. The system continues to operate when a node fails, other nodes pick up the workload while the node is offline. Scale-out, fault-tolerant products are built on distributed systems.

Analyzing Exmatter: A Ransomware Data Exfiltration Tool

Having conducted more than 3,200 incident response engagements in 2021, Kroll’s Threat Intelligence team now tracks more than 200 ransomware threat actor groups. Kroll’s global Incident Response teams are very familiar with actions traditionally associated with a network intrusion, from initial access to lateral movement to privilege escalation to data exfiltration—and in the case of financially motivated actors, ransomware deployment.

Office Documents and Cloud Apps: Perfect for Malware Delivery

Microsoft Word, Excel, PowerPoint, and other Office document formats are popular among attackers, who abuse them to infect their victims with ransomware, infostealers, backdoors, and other malware. In this article, we look at the anatomy of a recent Office document attack from the victim’s perspective, highlight the most common types of Office document attacks seen today, and suggest strategies to reduce your risk of becoming the latest victim.

Ransomware Attacks: How to Mitigate Risk and Protect Your Data

Ransomware is not a new threat, but the tactics that attackers are using to access corporate infrastructures and steal resources has evolved. With the continuation of remote work and data being stored on the cloud, attackers only need to compromise one user, app or device to gain access. Learn more about how these attacks happen.

Protestware is trending in open source: 4 different types and their impact

A few days ago, Snyk reported on a new type of threat vector in the open source community: protestware. The advisory was about a transitive vulnerability — peacenotwar — in node-ipc that impacted the supply chain of a great deal of developers. Snyk uses various intel threat feeds and algorithms to monitor chatter on potential threats to open source, and we believe this may just be the tip of a protestware iceberg.

Conti Ransomware: An Analysis of Key Findings

Amidst the turmoil of the Ukraine-Russia conflict, incident responders and ransomware researchers observed several ransomware gangs publish statements on their dark web blog sites. Some actors asserted the apolitical nature of their operations, while others clearly favored a side. Most notably, the Conti ransomware group posted a public statement in support of Russia with a stern warning of retaliation on February 25, 2022.

As tax deadlines approach, Emotet malware disguises itself in an IRS email

With just a few weeks until the April 15 deadline for US individuals and businesses to file their tax returns, scammers are as busy as ever. Security researchers at Cofsense have warned that they have seen a number of malicious email campaigns which pose as communications from the Internal Revenue Service (IRS). The emails which purport to come from “IRS.gov”, claim to contain tax forms (such as a W-9) that need to be filled out by the recipient.

Tackling NCSC Guidance - Part 2 (Data Security)

In part one of this two-part blog series, we analyzed the UK National Cyber Security Centre’s (NCSC) guidance relating to backups and data protection. Now in this post, we will examine NCSC’s guidance around mitigating malware and ransomware attacks. Recall that NCSC, at present, provides information and practical guidance in various articles on its website rather than formal requirements or regulations.

Falcon OverWatch Threat Hunting Uncovers Ongoing NIGHT SPIDER Zloader Campaign

Over recent months, the CrowdStrike Falcon OverWatch™ team has tracked an ongoing, widespread intrusion campaign leveraging bundled.msi installers to trick victims into downloading malicious payloads alongside legitimate software. These payloads and scripts were used to perform reconnaissance and ultimately download and execute NIGHT SPIDER’s Zloader trojan, as detailed in CrowdStrike Falcon X™ Premium reporting.

Detecting HermeticWiper

As stated in our previous threat advisory STRT-TA02 in regards to destructive software, past historical data suggests that for malicious actors to succeed in long-standing campaigns they must improve and add new ways of making their payloads stealthier, resistant, and damaging. HermeticWiper introduces some unique features, applying destructive actions on compromised hosts.

To Be CONTInued? Conti Ransomware Heavy Leaks

There is a war going on. We see a twist in the cyber world considering recent events. While some groups take sides, whether in favor of Russia or Ukraine, some groups have gone MIA, and others are completely ignoring and continuing with their usual business model. And then we have Conti, which, as it appears, took the biggest tumble. Conti is one of the most popular ransomware groups of our era.

How to Mitigate the Risk of Ransomware Attacks

Ransomware attacks are rapidly increasing in frequency and cost. According to security experts, ransomware was a $20 billion industry in 2021, with an attack happening every 11 seconds according to Cybersecurity Ventures. Organizations victimized by these attacks can lose access to their networks and data, incur steep financial losses, and suffer significant reputation damage. Watch our on-demand webinar of world-renowned cybersecurity expert Dr. Eric Cole and Keeper CEO Darren Guccione for a forward-looking conversation around.
