The Federal Police of Brazil on Wednesday announced it had arrested an individual for purported links to the notorious LAPSUS$ extortionist gang. The arrest was made as part of a new law enforcement effort, dubbed Operation Dark Cloud, that was launched in August 2022, the agency noted. Not much is known about the suspect other than the fact that the person could be a teenager. The Polícia Federal said it commenced its investigation in December 2021 following an attack on websites under Brazil's  Ministry of Health , resulting in the alleged exfiltration of 50TB of data and  temporary unavailability  of COVID-19 vaccination information of millions of citizens. Other federal government portals targeted by the LAPSUS$ group in Brazil include the Ministry of Economy, Comptroller General of the Union, and the Federal Highway Police. "The crimes determined in the police investigation are those of criminal organization, invasion of a computer device, interruption or distu...

Cybersecurity researchers have shared more details about a now-patched security flaw in Azure Service Fabric Explorer (SFX) that could potentially enable an attacker to gain administrator privileges on the cluster. The vulnerability, tracked as  CVE-2022-35829 , carries a CVSS severity rating of 6.2 and was addressed by Microsoft as part of its  Patch Tuesday updates  last week. Orca Security, which  discovered and reported  the flaw to the tech giant on August 11, 2022, dubbed the vulnerability  FabriXss  (pronounced "fabrics"). It impacts Azure Fabric Explorer version 8.1.316 and prior. SFX is described by Microsoft as an  open-source tool  for inspecting and managing  Azure Service Fabric  clusters, a distributed systems platform that's used to build and deploy microservices-based cloud applications. The vulnerability is rooted in the fact that a user with  permissions  to "Create Compose Application" through the...

An advanced persistent threat (APT) group of Chinese origin codenamed  DiceyF  has been linked to a string of attacks aimed at online casinos in Southeast Asia for years. Russian cybersecurity company Kaspersky said the activity aligns with another set of intrusions attributed to  Earth Berberoka  (aka  GamblingPuppet ) and  DRBControl , citing tactical and targeting similarities as well as the abuse of secure messaging clients. "Possibly we have a mix of espionage and [intellectual property] theft, but the true motivations remain a mystery," researchers Kurt Baumgartner and Georgy Kucherin  said  in a technical write-up published this week. The starting point of the investigation was in November 2021 when Kaspersky said it detected multiple  PlugX loaders  and other payloads that were deployed via an employee monitoring service and a security package deployment service. The initial infection method – the distribution of the frame...

In the world of insurance providers and policies, cyber insurance is a fairly new field. And many security teams are trying to wrap their heads around it.  What is it and do they need it? And with what time will they spend researching how to integrate cyber insurance into their strategy?  For small security teams, this is particularly challenging as they contend with limited resources. Luckily, there's a  new eBook  dedicated to helping small security teams better understand cyber insurance policies and how they may impact an organization's cybersecurity measures. Background In 1997, the "Internet Security Liability" (ISL) insurance policy was launched at the International Risk Insurance Management Society's convention in Honolulu. Underwritten by AIG, ISL insurance was designed to protect ecommerce retailers like Amazon that were collecting sensitive customer data and storing it on internal networks. It is credited as one of the very first cyber insurance poli...

Details have emerged about a previously undocumented and fully undetectable (FUD) PowerShell backdoor that gains its stealth by disguising itself as part of a Windows update process. "The covert self-developed tool and the associated C2 commands seem to be the work of a sophisticated, unknown threat actor who has targeted approximately 100 victims," Tomer Bar, director of security research at SafeBreach,  said  in a new report. Attributed to an  unnamed threat actor , attack chains involving the malware commence with a weaponized  Microsoft Word document  that, per the company, was uploaded from Jordan on August 25, 2022. Metadata associated with the lure document indicates that the initial intrusion vector is a LinkedIn-based spear-phishing attack, which ultimately leads to the execution of a PowerShell script via a piece of embedded macro code. "The Macro drops 'updater.vbs,' creates a scheduled task pretending to be part of a Windows update, which will ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday released two Industrial Control Systems (ICS)  advisories  pertaining to severe flaws in Advantech R-SeeNet and Hitachi Energy APM Edge appliances. This consists of three weaknesses in the R-SeeNet monitoring solution, successful exploitation of which "could result in an unauthorized attacker remotely deleting files on the system or allowing remote code execution." The list of issues, which affect R-SeeNet Versions 2.4.17 and prior, is as follows - CVE-2022-3385 and CVE-2022-3386  (CVSS scores: 9.8) - Two stack-based buffer overflow flaws that could lead to remote code execution CVE-2022-3387  (CVSS score: 6.5) - A path traversal flaw that could enable a remote attacker to delete arbitrary PDF files Patches have been made available in version  R-SeeNet version 2.4.21  released on September 30, 2022. Also published by CISA is an update to a December 2021 advisory about mult...

Both cryptocurrency and ransomware are nothing new in the digital world; both have been there for a very long time, which was enough for them to find common pieces for starting their relationship. Ransomware can be like a virtual car that works on all types of fuels, and crypto is the one that is currently most recommended. No one can argue that 2020 was the year of ransomware in the cyber world, but it wasn't due to the fact that cybercriminals chose ransomware just because they knew how to attack properly. It's because of the fact that crypto rose mostly this year, along with the new normal of the digital world. It gave them a new cause to stick to ransomware, thanks to the anonymous payments that can be made using a cryptocurrency.  How does ransomware work?  Ransomware is a malware type that encrypts the victim's files, whether it's a random user or an organization, leading to denying them access to those files on their personal devices. And the key to gaining ...
