An advanced persistent threat (APT) hacking group operating with motives that likely align with Palestine has embarked on a new campaign that takes advantage of a previously undocumented implant called NimbleMamba . The intrusions leveraged a sophisticated attack chain targeting Middle Eastern governments, foreign policy think tanks, and a state-affiliated airline, enterprise security firm Proofpoint  said  in a report, attributing the covert operation to a threat actor tracked as Molerats (aka TA402). Notorious for continuously updating their malware implants and their delivery methods, the APT group was most recently linked to an  espionage offensive  aimed at human rights activists and journalists in Palestine and Turkey, while a previous attack exposed in June 2021 resulted in the deployment of a backdoor called  LastConn . But the lull in the activities has been offset by the operators actively working to retool their arsenal, resulting in the developm...

A detailed examination of a Pay-per-install (PPI) malware service called PrivateLoader has revealed its crucial role in the delivery of a variety of malware such as  SmokeLoader ,  RedLine Stealer ,  Vidar ,  Raccoon , and  GCleaner  since at least May 2021. Loaders are malicious programs used for loading additional executables onto the infected machine. With PPI malware services such as PrivateLoader, malware operators pay the service owners to get their payloads "installed" based on the targets provided. "The accessibility and moderate costs allow malware operators to leverage these services as another weapon for rapid, bulk and geo-targeted malware infections," cybersecurity firm Intel 471  said  in a new report shared with The Hacker News. PrivateLoader, written in the C++ programming language, is designed to retrieve URLs for the malicious payloads to be deployed on the infected host, with the distribution primarily relying on a network...

A financially motivated campaign that targets Android devices and spreads mobile malware via SMS phishing techniques since at least 2018 has spread its tentacles to strike victims located in France and  Germany  for the first time. Dubbed  Roaming Mantis , the latest spate of activities observed in 2021 involve sending fake shipping-related texts containing a URL to a landing page from where Android users are infected with a banking trojan known as Wroba whereas iPhone users are redirected to a phishing page that masquerades as the official Apple website. The top affected countries, based on telemetry data gathered by Kaspersky between July 2021 and January 2022, are France, Japan, India, China, Germany, and Korea. Also tracked under the names  MoqHao  and XLoader (not to be confused with the info-stealer malware of the same name  targeting Windows and macOS ), the group's activity has continued to expand geographically even as the operators broadened ...

Two different Android banking Trojans, FluBot and Medusa, are relying on the same delivery vehicle as part of a simultaneous attack campaign, according to new research published by ThreatFabric. The ongoing side-by-side infections, facilitated through the same smishing (SMS phishing) infrastructure, involved the overlapping usage of "app names, package names, and similar icons," the Dutch mobile security firm said. Medusa, first discovered targeting Turkish financial organizations in July 2020, has undergone several iterations, chief among which is the ability to abuse accessibility permissions in Android to siphon funds from banking apps to an account controlled by the attacker. "Medusa sports other dangerous features like keylogging, accessibility event logging, and audio and video streaming — all these capabilities provide actors with almost full access to [a] victim's device," the researchers  said . The malware-ridden apps used in conjunction with Flu...

The wide-ranging adoption of cloud facilities and the subsequent mushrooming of organizations' networks, combined with the recent migration to remote work, had the direct consequence of a massive expansion of organizations' attack surface and led to a growing number of blind spots in connected architectures. The unforeseen  results of this expanded and attack surface  with fragmented monitoring has been a marked increase in the number of successful cyber-attacks, most notoriously, ransomware, but covering a range of other types of attacks as well. The main issues are unmonitored blind spots used by cyber-attackers to breach organizations' infrastructure and escalate their attack or move laterally, seeking valuable information.  The problem lies in discovery. Most organizations have evolved faster than their ability to keep track of all the moving parts involved and to catch up to catalog all past and present assets is often viewed as a complex and resource-heavy task w...

Microsoft on Monday said it's taking steps to disable Visual Basic for Applications (VBA) macros by default across its products, including Word, Excel, PowerPoint, Access, and Visio, for documents downloaded from the web in an attempt to eliminate an entire class of attack vector. "Bad actors send macros in Office files to end users who unknowingly enable them, malicious payloads are delivered, and the impact can be severe including malware, compromised identity, data loss, and remote access," Kellie Eickmeyer  said  in a post announcing the move. While the company does warn users about permitting macros in Office files, unsuspecting victims — e.g., recipients of phishing emails — can still be lured into enabling the feature, effectively granting the attackers the ability to gain an initial foothold into the system. As part of the new change, when a user opens an attachment or downloads from the internet an untrusted Office file containing macros, the app displays a ...

Microsoft last week announced that it's temporarily disabling the MSIX ms-appinstaller protocol handler in Windows following evidence that a security vulnerability in the installer component was exploited by threat actors to deliver malware such as Emotet, TrickBot, and Bazaloader. MSIX , based on a combination of .msi, .appx, App-V and ClickOnce installation technologies, is a universal Windows app package format that allows developers to distribute their applications for the desktop operating system and  other platforms . ms-appinstaller, specifically, is designed to help users  install a Windows app  by simply clicking a link on a website. But a spoofing vulnerability uncovered in Windows App Installer ( CVE-2021-43890 , CVSS score: 7.1) meant that it could be tricked into installing a rogue app that was never intended to be installed by the user via a malicious attachment used in phishing campaigns. Although Microsoft released initial patches to address this fla...
