An advanced persistent threat (APT) group with ties to Iran has refreshed its malware toolset to include a new backdoor dubbed  Marlin  as part of a long-running espionage campaign that started in April 2018. Slovak cybersecurity company ESET attributed the attacks — codenamed "Out to Sea"  — to a threat actor called  OilRig  (aka APT34), while also conclusively connecting its activities to a second Iranian group tracked under the name  Lyceum  (Hexane aka  SiameseKitten ). "Victims of the campaign include diplomatic organizations, technology companies, and medical organizations in Israel, Tunisia, and the United Arab Emirates," ESET noted in its  T3 2021 Threat Report  shared with The Hacker News. Active since at least 2014, the hacking group is known to strike Middle Eastern governments and a variety of business verticals, including chemical, energy, financial, and telecommunications. In April 2021, the actor targeted a Lebanese e...

The Russia-linked threat actor known as APT29 targeted European diplomatic missions and Ministries of Foreign Affairs as part of a series of spear-phishing campaigns mounted in October and November 2021. According to ESET's  T3 2021 Threat Report  shared with The Hacker News, the intrusions paved the way for the deployment of Cobalt Strike Beacon on compromised systems, followed by leveraging the foothold to drop additional malware for gathering information about the hosts and other machines in the same network. Also tracked under the names The Dukes, Cozy Bear, and Nobelium, the advanced persistent threat group is an infamous cyber-espionage group that has been active for more than a decade, with its attacks targeting Europe and the U.S., before it gained widespread attention for the  supply‐chain compromise  of SolarWinds, leading to further infections in several downstream entities, including U.S. government agencies in 2020. The spear-phishing attacks commen...

Microsoft on Tuesday rolled out its monthly security updates with  fixes for 51 vulnerabilities  across its software line-up consisting of Windows, Office, Teams, Azure Data Explorer, Visual Studio Code, and other components such as Kernel and Win32k. Among the 51 defects closed, 50 are rated Important and one is rated Moderate in severity, making it one of the rare Patch Tuesday updates without any fixes for Critical-rated vulnerabilities. This is also in addition to  19 more flaws  the company addressed in its Chromium-based Edge browser. None of the security vulnerabilities are listed as under active exploit, while of the flaws —  CVE-2022-21989  (CVSS score: 7.8) — has been classified as a publicly disclosed zero-day at the time of the release. The issue concerns a privilege escalation bug in Windows Kernel, with Microsoft warning of potential attacks exploiting the shortcoming. "Successful exploitation of this vulnerability requires an attacker to...

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...
