Europol Dismantles Ragnar Locker Ransomware Infrastructure, Nabs Key Developer

Oct 21, 2023 Ransomware / Malware
Europol on Friday announced the takedown of the infrastructure associated with Ragnar Locker ransomware, alongside the arrest of a "key target" in France. "In an action carried out between 16 and 20 October, searches were conducted in Czechia, Spain, and Latvia," the agency  said . "The main perpetrator, suspected of being a developer of the Ragnar group, has been brought in front of the examining magistrates of the Paris Judicial Court." Five other accomplices associated with the ransomware gang are said to have been interviewed in Spain and Latvia, with the servers and the data leak portal seized in the Netherlands, Germany, and Sweden. The effort is the latest coordinated exercise involving authorities from Czechia, France, Germany, Italy, Japan, Latvia, the Netherlands, Spain, Sweden, Ukraine, and the U.S. Two suspects associated with the ransomware crew were previously arrested from Ukraine in 2021. A year later, another member was apprehended in ...
Okta's Support System Breach Exposes Customer Data to Unidentified Threat Actors

Okta's Support System Breach Exposes Customer Data to Unidentified Threat Actors

Oct 21, 2023 Data Breach / Cyber Attack
Identity services provider Okta on Friday disclosed a new security incident that allowed unidentified threat actors to leverage stolen credentials to access its support case management system. "The threat actor was able to view files uploaded by certain Okta customers as part of recent support cases," David Bradbury, Okta's chief security officer, said . "It should be noted that the Okta support case management system is separate from the production Okta service, which is fully operational and has not been impacted." The company also emphasized that its Auth0/CIC case management system was not impacted by the breach, noting it has directly notified customers who have been affected. However, it said that the customer support system is also used to upload HTTP Archive (HAR) files to replicate end user or administrator errors for troubleshooting purposes. "HAR files can also contain sensitive data, including cookies and session tokens, that malici...
Cisco Zero-Day Exploited to Implant Malicious Lua Backdoor on Thousands of Devices

Cisco Zero-Day Exploited to Implant Malicious Lua Backdoor on Thousands of Devices

Oct 21, 2023 Zero-Day / Vulnerability
Cisco has warned of a new zero-day flaw in IOS XE that has been actively exploited by an unknown threat actor to deploy a  malicious Lua-based implant  on susceptible devices. Tracked as  CVE-2023-20273  (CVSS score: 7.2), the issue relates to a privilege escalation flaw in the web UI feature and is said to have been used alongside CVE-2023-20198 (CVSS score: 10.0) as part of an exploit chain. "The attacker first exploited CVE-2023-20198 to gain initial access and issued a privilege 15 command to create a local user and password combination," Cisco  said  in an updated advisory published Friday. "This allowed the user to log in with normal user access." "The attacker then exploited another component of the web UI feature, leveraging the new local user to elevate privilege to root and write the implant to the file system," a shortcoming that has been assigned the identifier CVE-2023-20273. A Cisco spokesperson told The Hacker News that a fix that cove...

Malvertisers Using Google Ads to Target Users Searching for Popular Software

Malvertisers Using Google Ads to Target Users Searching for Popular Software

Oct 20, 2023 Malvertising / Cyber Threat
Details have emerged about a malvertising campaign that leverages Google Ads to direct users searching for popular software to fictitious landing pages and distribute next-stage payloads. Malwarebytes, which discovered the activity,  said  it's "unique in its way to fingerprint users and distribute time sensitive payloads." The attack singles out users searching for Notepad++ and PDF converters to serve bogus ads on the Google search results page that, when clicked, filters out bots and other unintended IP addresses by showing a decoy site. Should the visitor be deemed of interest to the threat actor, the victim is redirected to a replica website advertising the software, while silently fingerprinting the system to determine if the request is originating from a virtual machine. Users who fail the check are taken to the legitimate Notepad++ website, while a potential target is assigned a unique ID for "tracking purposes but also to make each download unique and t...
Vietnamese Hackers Target U.K., U.S., and India with DarkGate Malware

Vietnamese Hackers Target U.K., U.S., and India with DarkGate Malware

Oct 20, 2023 Malware / Cyber Attack
Attacks leveraging the DarkGate commodity malware targeting entities in the U.K., the U.S., and India have been linked to Vietnamese actors associated with the use of the infamous  Ducktail stealer . "The overlap of tools and campaigns is very likely due to the effects of a cybercrime marketplace," WithSecure  said  in a report published today. "Threat actors are able to acquire and use multiple different tools for the same purpose, and all they have to do is come up with targets, campaigns, and lures." The development comes amid an  uptick in malware campaigns  using DarkGate in recent months, primarily driven by its author's decision to rent it out on a malware-as-a-service (MaaS) basis to other threat actors after using it privately since 2018. It's not just DarkGate and Ducktail, for the Vietnamese threat actor cluster responsible for these campaigns is leveraging same or very similar lures, themes, targeting, and delivery methods to also deliver  ...
