The landscape of cybersecurity in financial services is undergoing a rapid transformation. Cybercriminals are exploiting advanced technologies and methodologies, making traditional security measures obsolete. The challenges are compounded for community banks that must safeguard sensitive financial data against the same level of sophisticated threats as larger institutions, but often with more limited resources. The FinServ Threat Landscape Recent trends show an alarming increase in sophisticated cyber-attacks. Cybercriminals now deploy advanced techniques like deep fake technology and AI-powered attacks, making it increasingly difficult for banks to differentiate between legitimate and malicious activities. These developments necessitate a shift towards more sophisticated and adaptive cybersecurity measures. Take these industry statistics, for example. Financial firms report 703 cyberattack attempts per week.1 On average, 270 attacks (entailing unauthorized access of data, appl

The infamous malware loader and initial access broker known as  Bumblebee  has resurfaced after a four-month absence as part of a new phishing campaign observed in February 2024. Enterprise security firm Proofpoint said the activity targets organizations in the U.S. with voicemail-themed lures containing links to OneDrive URLs. "The URLs led to a Word file with names such as "ReleaseEvans#96.docm" (the digits before the file extension varied)," the company  said  in a Tuesday report. "The Word document spoofed the consumer electronics company Humane." Opening the document leverages VBA macros to launch a PowerShell command to download and execute another PowerShell script from a remote server that, in turn, retrieves and runs the Bumblebee loader. Bumblebee,  first spotted  in March 2022, is mainly designed to download and execute follow-on payloads such as ransomware. It has been put to use by multiple crimeware threat actors that previously observe

As a vCISO, you are responsible for your client's cybersecurity strategy and risk governance. This incorporates multiple disciplines, from research to execution to reporting. Recently, we published a comprehensive playbook for vCISOs, "Your First 100 Days as a vCISO – 5 Steps to Success" , which covers all the phases entailed in launching a successful vCISO engagement, along with recommended actions to take, and step-by-step examples.  Following the success of the playbook and the requests that have come in from the MSP/MSSP community, we decided to drill down into specific parts of vCISO reporting and provide more color and examples. In this article, we focus on how to create compelling narratives within a report, which has a significant impact on the overall MSP/MSSP value proposition.  This article brings the highlights of a recent guided workshop we held, covering what makes a successful report and how it can be used to enhance engagement with your cyber security clients.

Cybersecurity researchers have uncovered an "implementation vulnerability" that has made it possible to reconstruct encryption keys and decrypt data locked by Rhysida ransomware. The findings were published last week by a group of researchers from Kookmin University and the Korea Internet and Security Agency (KISA). "Through a comprehensive analysis of Rhysida Ransomware, we identified an implementation vulnerability, enabling us to regenerate the encryption key used by the malware," the researchers  said . The development marks the first successful decryption of the ransomware strain, which first made its appearance in May 2023. A  recovery tool  is being distributed through KISA. The study is also the latest to achieve data decryption by exploiting implementation vulnerabilities in ransomware, after  Magniber v2 , Ragnar Locker,  Avaddon , and  Hive . Rhysida , which is known to share overlaps with another ransomware crew called Vice Society, leverages a ta

The U.S. Department of State has  announced  monetary rewards of up to $10 million for information about individuals holding key positions within the Hive ransomware operation. It is also giving away an additional $5 million for specifics that could lead to the arrest and/or conviction of any person "conspiring to participate in or attempting to participate in Hive ransomware activity." The multi-million-dollar rewards come a little over a year after a coordinated law enforcement effort  covertly infiltrated and dismantled  the darknet infrastructure associated with the Hive ransomware-as-a-service (RaaS) gang. One person with suspected ties to the group was  arrested  in Paris in December 2023. Hive, which emerged in mid-2021, targeted more than 1,500 victims in over 80 countries, netting about $100 million in illegal revenues. In November 2023, Bitdefender  revealed  that a new ransomware group called Hunters International had acquired the source code and infrastructure

Apple macOS users are the target of a new Rust-based backdoor that has been operating under the radar since November 2023. The backdoor,  codenamed   RustDoor  by Bitdefender, has been found to impersonate an update for Microsoft Visual Studio and target both Intel and Arm architectures. The exact initial access pathway used to propagate the implant is currently not known, although it's said to be distributed as FAT binaries that contain Mach-O files. Multiple variants of the malware with minor modifications have been detected to date, likely indicating active development. The earliest sample of RustDoor dates back to November 2, 2023. It comes with a wide range of commands that allow it to gather and upload files, and harvest information about the compromised endpoint. Some versions also include configurations with details about what data to collect, the list of targeted extensions and directories, and the directories to exclude. The captured information is then exfiltrate

The operators of  Raspberry Robin  are now using two new one-day exploits to achieve local privilege escalation, even as the malware continues to be refined and improved to make it stealthier than before. This means that "Raspberry Robin has access to an exploit seller or its authors develop the exploits themselves in a short period of time," Check Point  said  in a report this week. Raspberry Robin (aka QNAP worm), first documented in 2021, is an  evasive malware family  that's known to act as one of the  top initial access facilitators  for other malicious payloads, including ransomware. Attributed to a threat actor named Storm-0856 (previously DEV-0856), it's propagated via several entry vectors, including infected USB drives, with Microsoft  describing  it as part of a "complex and interconnected malware ecosystem" with ties to other e-crime groups like  Evil Corp, Silence, and TA505 . Raspberry Robin's use of one-day exploits such as CVE-2020-

JetBrains is alerting customers of a critical security flaw in its TeamCity On-Premises continuous integration and continuous deployment (CI/CD) software that could be exploited by threat actors to take over susceptible instances. The vulnerability, tracked as  CVE-2024-23917 , carries a CVSS rating of 9.8 out of 10, indicative of its severity. "The vulnerability may enable an unauthenticated attacker with HTTP(S) access to a TeamCity server to bypass authentication checks and gain administrative control of that TeamCity server," the company  said . The issue impacts all TeamCity On-Premises versions from 2017.1 through 2023.11.2. It has been addressed in version 2023.11.3. An unnamed external security researcher has been credited with discovering and reporting the flaw on January 19, 2024. Users who are unable to update their servers to version 2023.11.3 can alternately download a security patch plugin to apply fixes for the flaw. "If your server is publicly acce

Threat actors are leveraging bogus Facebook job advertisements as a lure to trick prospective targets into installing a new Windows-based stealer malware codenamed  Ov3r_Stealer . "This malware is designed to steal credentials and crypto wallets and send those to a Telegram channel that the threat actor monitors," Trustwave SpiderLabs said in a report shared with The Hacker News. Ov3r_Stealer is capable of siphoning IP address-based location, hardware info, passwords, cookies, credit card information, auto-fills, browser extensions, crypto wallets, Microsoft Office documents, and a list of antivirus products installed on the compromised host. While the exact end goal of the campaign is unknown, it's likely that the stolen information is offered for sale to other threat actors. Another possibility is that Ov3r_Stealer could be updated over time to act as a  QakBot-like loader  for additional payloads, including ransomware. The starting point of the attack is a weapo

An INTERPOL-led collaborative operation targeting phishing, banking malware, and ransomware attacks has led to the identification of 1,300 suspicious IP addresses and URLs. The  law enforcement effort , codenamed  Synergia , took place between September and November 2023 in an attempt to blunt the "growth, escalation and professionalization of transnational cybercrime." Involving 60 law enforcement agencies spanning 55 member countries, the exercise paved the way for the detection of more than 1,300 malicious servers, 70% of which have already been taken down in Europe. Hong Kong and Singapore authorities took down 153 and 86 servers, respectively. Servers, as well as electronic devices, were confiscated following over 30 house searches. Seventy suspects have been identified to date, and 31 from Europe, South Sudan, and Zimbabwe have been arrested. Singapore-headquartered Group-IB, which also contributed to the operation,  said  it identified "more than 500 IP addr

Threat hunters have identified a new campaign that delivers the  ZLoader  malware, resurfacing nearly two years after the botnet's infrastructure was dismantled in April 2022. A new variant of the malware is said to have been in development since September 2023, Zscaler ThreatLabz said in an analysis published this month. "The new version of ZLoader made significant changes to the loader module, which added RSA encryption, updated the domain generation algorithm, and is now compiled for 64-bit Windows operating systems for the first time," researchers Santiago Vicente and Ismael Garcia Perez  said . ZLoader, also known by the names Terdot, DELoader, or Silent Night, is an offshoot of the Zeus banking trojan that first surfaced in 2015, before pivoting to functioning as a loader for next-stage payloads, including ransomware. Typically distributed via phishing emails and malicious search engine ads, ZLoader suffered a huge blow after a group of companies led by Micros

In nearly every segment of our lives, AI (artificial intelligence) now makes a significant impact: It can deliver better healthcare diagnoses and treatments; detect and reduce the risk of financial fraud; improve inventory management; and serve up the right recommendation for a streaming movie on Friday night. However, one can also make a strong case that some of AI's most significant impacts are in cybersecurity. AI's ability to learn, adapt, and predict rapidly evolving threats has made it an indispensable tool in protecting the world's businesses and governments. From basic applications like spam filtering to advanced predictive analytics and AI-assisted response, AI serves a critical role on the front lines, defending our digital assets from cyber criminals. The future for AI in cybersecurity is not all rainbows and roses, however. Today we can see the early signs of a significant shift, driven by the democratization of AI technology. While AI continues to empower organizations

Cybersecurity researchers have detected in the wild yet another variant of the Phobos ransomware family known as  Faust . Fortinet FortiGuard Labs, which detailed the latest iteration of the ransomware, said it's being propagated by means of an infection that delivers a Microsoft Excel document (.XLAM) containing a VBA script. "The attackers utilized the Gitea service to store several files encoded in Base64, each carrying a malicious binary," security researcher Cara Lin  said  in a technical report published last week. "When these files are injected into a system's memory, they initiate a file encryption attack." Faust is the latest addition to several ransomware variants from the Phobos family, including Eking, Eight, Elbie, Devos, and 8Base. It's worth noting that Faust was  previously documented  by Cisco Talos in November 2023. The cybersecurity firm described the variant as active since 2022 and "does not target specific industries or re
