State-sponsored threat actors from the Democratic People's Republic of Korea (DPRK) have been found targeting blockchain engineers of an unnamed crypto exchange platform via Discord with a novel macOS malware dubbed  KANDYKORN . Elastic Security Labs said the activity, traced back to April 2023, exhibits overlaps with the infamous adversarial collective  Lazarus Group , citing an analysis of the network infrastructure and techniques used. "Threat actors lured blockchain engineers with a Python application to gain initial access to the environment," security researchers Ricardo Ungureanu, Seth Goodwin, and Andrew Pease  said  in a report published today. "This intrusion involved multiple complex stages that each employed deliberate defense evasion techniques." This is not the first time the Lazarus Group has leveraged macOS malware in its attacks. Earlier this year, the threat actor was observed distributing a backdoored PDF application that culminated in t...

The Russia-linked hacking crew known as Turla has been observed using an updated version of a known second-stage backdoor referred to as Kazuar. The new findings come from Palo Alto Networks Unit 42, which is tracking the adversary under its constellation-themed moniker  Pensive Ursa . "As the code of the upgraded revision of Kazuar reveals, the authors put special emphasis on Kazuar's ability to operate in stealth, evade detection and thwart analysis efforts," security researchers Daniel Frank and Tom Fakterman  said  in a technical report. "They do so using a variety of advanced anti-analysis techniques and by protecting the malware code with effective encryption and obfuscation practices." Pensive Ursa, active since at least 2004, is attributed to the Russian Federal Security Service (FSB). Earlier this July, the Computer Emergency Response Team of Ukraine (CERT-UA)  implicated  the threat group to attacks targeting the defense sector in Ukraine and East...

F5 is warning of active abuse of a critical security flaw in BIG-IP less than a week after its public disclosure, resulting in the execution of arbitrary system commands as part of an exploit chain. Tracked as  CVE-2023-46747  (CVSS score: 9.8), the  vulnerability  allows an unauthenticated attacker with network access to the BIG-IP system through the management port to achieve code execution. A proof-of-concept (PoC)  exploit  has since been made  available  by ProjectDiscovery. It impacts the following versions of the software - 17.1.0 (Fixed in 17.1.0.3 + Hotfix-BIGIP-17.1.0.3.0.75.4-ENG) 16.1.0 - 16.1.4 (Fixed in 16.1.4.1 + Hotfix-BIGIP-16.1.4.1.0.50.5-ENG) 15.1.0 - 15.1.10 (Fixed in 15.1.10.2 + Hotfix-BIGIP-15.1.10.2.0.44.2-ENG) 14.1.0 - 14.1.5 (Fixed in 14.1.5.6 + Hotfix-BIGIP-14.1.5.6.0.10.6-ENG) 13.1.0 - 13.1.5 (Fixed in 13.1.5.1 + Hotfix-BIGIP-13.1.5.1.0.20.2-ENG) Now the company is  alerting  that it has "observed th...

The threat actor known as  Arid Viper  (aka APT-C-23, Desert Falcon, or TAG-63) has been attributed as behind an Android spyware campaign targeting Arabic-speaking users with a counterfeit dating app designed to harvest data from infected handsets. "Arid Viper's Android malware has a number of features that enable the operators to surreptitiously collect sensitive information from victims' devices and deploy additional executables," Cisco Talos  said  in a Tuesday report. Active since at least 2017, Arid Viper is a cyber espionage that's aligned with  Hamas , an Islamist militant movement that governs the Gaza Strip. The cybersecurity firm said there is no evidence connecting the campaign to the  ongoing   Israel-Hamas war . The activity is believed to have commenced no earlier than April 2022. Interestingly, the mobile malware shares source code similarities with a non-malicious online dating application called Skipped, suggesting that the opera...

Cybersecurity researchers have uncovered a new set of malicious packages published to the NuGet package manager using a lesser-known method for malware deployment. Software supply chain security firm ReversingLabs described the campaign as coordinated and ongoing since August 1, 2023, while linking it to a  host of rogue NuGet packages  that were observed delivering a remote access trojan called SeroXen RAT . "The threat actors behind it are tenacious in their desire to plant malware into the NuGet repository, and to continuously publish new malicious packages," Karlo Zanki, reverse engineer at ReversingLabs,  said  in a report shared with The Hacker News. The names of some of the packages are below - Pathoschild.Stardew.Mod.Build.Config KucoinExchange.Net Kraken.Exchange DiscordsRpc SolanaWallet Monero Modern.Winform.UI MinecraftPocket.Server IAmRoot ZendeskApi.Client.V2 Betalgo.Open.AI Forge.Open.AI Pathoschild.Stardew.Mod.BuildConfig CData.NetS...
