CISA recently advised U.S. business leaders to protect their companies from destructive malware that has been seen targeting Ukraine. This emphasizes the importance of having the right technologies in place. The automated detection and protection capabilities of the CrowdStrike Falcon platform protect customers from this malware, provide them with visibility into their environments and allow for intelligent monitoring of cloud resources.

Though the level of fear of Covid 19 has diminished, there are other fears surrounding the 2022 Olympic games. Fears of telecom disruptions and ransomware attacks are founded, and the damage that could be caused has increased with the reliance on technology to broadcast the Games, which kicks off on February 4. Organizers are preparing for the kind of cyberattack that temporarily paralyzed IT systems ahead of the official opening ceremonies of the 2018 Pyeongchang Winter Olympics in South Korea.

WannaCry malware was first discovered in May 2017 and a patch was released roughly two months prior to its public release. However, 230,000 computers were globally affected by WannaCry as of 3/31/2021. It is unfortunate to hear, but many companies remain vulnerable to this attack due to unpatched systems. We often see that by the time some companies update their systems, they have already experienced a breach.

Threat actors go to great lengths to hide the intentions of the malware they produce. For instance, binaries are often encrypted or packed. Typically, encrypting binaries is enough to thwart automated analysis platforms such as Cuckoo or other automated malware sandboxes. The implication is that automated detection of malicious programs might not be successful.

In November 2021, AT&T Alien Labs™ first published research on our discovery of new malware written in the open-source programming language Golang. The team named this malware “BotenaGo.” In this article, Alien Labs is updating that research with new information.

A new destructive malware called WhisperGate was discovered in mid-January 2022 targeting Ukrainian organizations. This threat emerged during geopolitical conflicts in Ukraine, masquerading as ransomware. However, this malware has a more destructive nature: wiping files and corrupting disks to prevent the OS from loading. Ukraine has suffered other cyberattacks that seem to be connected to WhisperGate, such as the defacement of many websites connected to their governments.

In my decade working in the cybersecurity industry, I’ve developed quite a few fond memories learning from talented security professionals. In 2015, I found myself working with Andy Pendergast at ThreatConnect. (As a little background, Andy is one of the fine folks who developed the Diamond Model for Intrusion Analysis. He is considered to be a veritable cybersecurity encyclopedia among his peers.) At the time, I was new to cyber threat intelligence (CTI).

On June 23, 2021, threat actors reported that they had stolen a terabyte of data from Saudi Aramco, a state-owned oil company in Saudi Arabia. The threat actors released samples of data they had procured after redacting critical information. They also claimed to have detailed information on Aramco’s employees, such as their full names, photographs, passport scans, emails, phone numbers, residence permit (Iqama card) numbers, job titles, employee ID numbers, and family information.

Late December 2021: A company coming off a record year for revenue growth was preparing to ramp down for a week to celebrate the December holidays. However, unbeknownst to the company, just a few days prior, one of its longest-serving employees had been recruited by a ransomware group. The employee had responded to a posting on a computer hacking forum asking for access to corporate networks in return for cash payouts.

On Jan. 15, 2022, a set of malware dubbed WhisperGate was reported to have been deployed against Ukrainian targets. The incident is widely reported to contain three individual components deployed by the same adversary, including a malicious bootloader that corrupts detected local disks, a Discord-based downloader and a file wiper. The activity occurred at approximately the same time multiple websites belonging to the Ukrainian government were defaced.

From nation-state threat actors to typical cybercriminals, the public sector faces a multitude of cybersecurity threats. At the same time, public-sector organizations struggle to maintain a robust cyber hygiene posture because they need to balance limited budgets with complex IT environments and highly interconnected ecosystems.

Elastic Security has verified a new destructive malware targeting Ukraine: Operation Bleeding Bear. Over the weekend, Microsoft released details about this multi-stage and destructive malware campaign that the Ukrainian National Cyber Security Coordination Center has been referring to as Operation Bleeding Bear.

Protecting your data in the cloud is fundamental to your security posture in terms of business continuity and disaster recovery. While Rubrik customers utilize the cloud every day to safely store off-site copies of their data, this blog is going to explain how we’ve made that practice even safer! We know that security threats to backup systems are on the rise, with hacking, malware, and even human error becoming more prevalent in the age of remote work.

Malware targeting Linux-based operating systems, commonly deployed in Internet of Things (IoT) devices, have increased by 35% in 2021 compared to 2020, according to current CrowdStrike threat telemetry, with the top three malware families accounting for 22% of all Linux-based IoT malware in 2021.

Since the return of the Qakbot Trojan in early September 2021, especially through SquirrelWaffle malicious spam campaigns, we’ve received a few Qakbot samples to analyze from our Trustwave DFIR and Global Threats Operations teams.

As the pandemic continues, organizations around the world are working hard to adapt to the “new normal.” This article highlights the key trends that we will face in 2022 and beyond. Ransomware attacks more than doubled in 2021 compared to 2020, with healthcare and utilities the most commonly targeted sectors. Moreover, attacks are getting more expensive, with the average ransomware payment leaping from US$312,000 in 2020 to $570,000 in 2021.

The early stages of an intrusion usually include initial access, execution, persistence, and command-and-control (C2) beaconing. When structured threats use zero-days, these first two stages are often not detected. It can often be challenging and time-consuming to identify persistence mechanisms left by an advanced adversary as we saw in the 2020 SUNBURST supply chain compromise. Could we then have detected SUNBURST in the initial hours or days by finding its C2 beacon?

It was 11 PM on a Friday in November of 2019. WED2B IT systems administrator Jamie Jeeves started receiving a barrage of email alerts warning that antivirus (AV) clients were crashing in the company’s central office. All prospects for a relaxing weekend vanished when Jeeves logged into the remote system to investigate the AV shutdowns. While checking the network’s file share, Jeeves noticed they were in trouble. Mass encryption of data was underway.

The TellYouThePass ransomware family was recently reported as a post-exploitation malicious payload used in conjunction with a remote code execution vulnerability in Apache Log4j library, dubbed Log4Shell. TellYouThePass was first reported in early 2019 as a financially motivated ransomware designed to encrypt files and demand payment for restoring them. Targeting both Windows and Linux systems, TellYouThePass ransomware re-emerged in mid-December 2021 along with other ransomware like Khonsari.

Naming themselves Night Sky, a new ransomware family was spotted on the first day of 2022, by the MalwareHunterTeam. They appear to work in the RaaS (Ransomware-as-a-Service) model, similar to other ransomware groups like REvil, LockBit, and Hive, publishing stolen data exfiltrated throughout the attack in a deep web site if the ransom is not paid by the victim. Currently, there are two companies listed on their deep web site, where the group has published the victim’s allegedly stolen data.

With our recent 7.16 Elastic Security product release, we improved our existing Linux malware feature by adding memory protection. In this blog, brought to you by Elastic’s Engineering Security Team, we lean into this recent advancement to show how we are protecting the world’s data from attack.

Nowadays, malware used to have several stages before it fully compromised the targeted host or machine. The very well-known initial stager is the “phishing email” that contains a malicious macro code or malicious URL link that will download either the actual loader or the next stager to download the actual payload.

Ransomware has quickly become one of the most prevalent cyber threats facing organizations today. Unfortunately, the cybercriminal community has latched onto this attack method because infections can quickly cause devastating damage to the victim, and strikes are incredibly easy to launch at scale. The best way to ensure that your organization does not fall victim to a ransomware attack is to understand what happens when an attacker injects this type of malware into a system.
