An Iranian threat actor has unleashed a new cyberespionage campaign against a possible Lebanese target with a backdoor capable of exfiltrating sensitive information from compromised systems. Cybersecurity firm Check Point attributed the operation to APT34, citing similarities with previous techniques used by the threat actor as well as based on its pattern of victimology. APT34  (aka OilRig) is known for its reconnaissance campaigns aligned with the strategic interests of Iran, primarily hitting financial, government, energy, chemical, and telecommunications industries in the Middle East. The group typically resorts to targeting individuals through the use of booby-trapped job offer documents, delivered directly to the victims via LinkedIn messages. Although the latest campaign bears some of the same hallmarks, the exact mode of delivery remains unclear as yet. The Word document analyzed by Check Point — which was  uploaded  to VirusTotal from Lebanon on January 10 — claims to of

Unpatched Fortinet VPN devices are being targeted in a series of attacks against industrial enterprises in Europe to deploy a new strain of ransomware called "Cring" inside corporate networks. At least one of the hacking incidents led to the temporary shutdown of a production site, said cybersecurity firm Kaspersky in a report published on Wednesday, without publicly naming the victim. The attacks happened in the first quarter of 2021, between January and March. "Various details of the attack indicate that the attackers had carefully analyzed the infrastructure of the targeted organization and prepared their own infrastructure and toolset based on the information collected at the reconnaissance stage,"  said  Vyacheslav Kopeytsev, a security researcher at Kaspersky ICS CERT. The disclosure comes days after the Federal Bureau of Investigation (FBI) and the Cybersecurity and Infrastructure Security Agency (CISA)  warned  of advanced persistent threat (APT) actor

Super Low RPO with Continuous Data Protection: Dial Back to Just Seconds Before an Attack Zerto , a Hewlett Packard Enterprise company, can help you detect and recover from ransomware in near real-time. This solution leverages continuous data protection (CDP) to ensure all workloads have the lowest recovery point objective (RPO) possible. The most valuable thing about CDP is that it does not use snapshots, agents, or any other periodic data protection methodology. Zerto has no impact on production workloads and can achieve RPOs in the region of 5-15 seconds across thousands of virtual machines simultaneously. For example, the environment in the image below has nearly 1,000 VMs being protected with an average RPO of just six seconds! Application-Centric Protection: Group Your VMs to Gain Application-Level Control   You can protect your VMs with the Zerto application-centric approach using Virtual Protection Groups (VPGs). This logical grouping of VMs ensures that your whole applica

Cybersecurity researchers have discovered yet another piece of wormable Android malware—but this time downloadable directly from the official Google Play Store—that's capable of propagating via WhatsApp messages. Disguised as a rogue Netflix app under the name of "FlixOnline," the malware comes with features that allow it to automatically reply to a victim's incoming WhatsApp messages with a payload received from a command-and-control (C&C) server.  "The application is actually designed to monitor the user's WhatsApp notifications, and to send automatic replies to the user's incoming messages using content that it receives from a remote C&C server," Check Point researchers said in an analysis published today. Besides masquerading as a Netflix app, the malicious "FlixOnline" app also requests intrusive permissions that allow it to create fake Login screens for other apps, with the goal of stealing credentials and gain access to

In what appears to be a fresh twist in Android malware, users of Gigaset mobile devices are encountering unwanted apps that are being downloaded and installed through a pre-installed system update app. "The culprit installing these malware apps is the Update app, package name  com.redstone.ota.ui , which is a pre-installed system app," Malwarebytes researcher Nathan Collier  said . "This app is not only the mobile device's system updater, but also an auto installer known as Android/PUP.Riskware.Autoins.Redstone." The development was  first reported  by German author and blogger Günter Born last week. While the issue seems to be mainly affecting Gigaset phones, devices from a handful of other manufacturers appear to be impacted as well. The full list of devices that come with the pre-installed auto-installer includes Gigaset GS270, Gigaset GS160, Siemens GS270, Siemens GS160, Alps P40pro, and Alps S20pro+. According to Malwarebytes, the Update app installs

Researchers on Tuesday revealed details of a new banking trojan targeting corporate users in Brazil at least since 2019 across various sectors such as engineering, healthcare, retail, manufacturing, finance, transportation, and government. Dubbed " Janeleiro " by Slovak cybersecurity firm ESET, the malware aims to disguise its true intent via lookalike pop-up windows that are designed to resemble the websites of some of the biggest banks in the country, including Itaú Unibanco, Santander, Banco do Brasil, Caixa Econômica Federal, and Banco Bradesco. "These pop-ups contain fake forms, aiming to trick the malware's victims into entering their banking credentials and personal information that the malware captures and exfiltrates to its [command-and-control] servers," ESET researchers Facundo Muñoz and Matías Porolli said in a write-up. This modus operandi is not new to banking trojans. In August 2020, ESET uncovered a Latin American (LATAM) banking trojan call

A new spear-phishing campaign is targeting professionals on LinkedIn with weaponized job offers in an attempt to infect targets with a sophisticated backdoor trojan called "more_eggs." To increase the odds of success, the phishing lures take advantage of malicious ZIP archive files that have the same name as that of the victims' job titles taken from their LinkedIn profiles. "For example, if the LinkedIn member's job is listed as Senior Account Executive—International Freight the malicious zip file would be titled Senior Account Executive—International Freight position (note the 'position' added to the end)," cybersecurity firm eSentire's Threat Response Unit (TRU)  said  in an analysis. "Upon opening the fake job offer, the victim unwittingly initiates the stealthy installation of the fileless backdoor, more_eggs." Campaigns delivering more_eggs using the  same modus operandi  have been spotted at least since 2018, with the backdo

Cybersecurity researchers on Tuesday disclosed details of a sophisticated campaign that deploys malicious backdoors for the purpose of exfiltrating information from a number of industry sectors located in Japan. Dubbed "A41APT" by Kaspersky researchers, the findings delve into a new slew of attacks undertaken by  APT10  (aka Stone Panda or Cicada) using previously undocumented malware to deliver as many as three payloads such as SodaMaster, P8RAT, and FYAnti. The long-running intelligence-gathering operation first came into the scene in March 2019, with activities spotted as recently as November 2020, when  reports  emerged of Japan-linked companies being targeted by the threat actor in over 17 regions worldwide. The fresh attacks uncovered by Kaspersky are said to have occurred in January 2021. The infection chain leverages a multi-stage attack process, with the initial intrusion happening via abuse of SSL-VPN by exploiting unpatched vulnerabilities or stolen credential

More than a week after Microsoft released a  one-click mitigation tool  to mitigate cyberattacks targeting on-premises Exchange servers, the company  disclosed  that patches have been applied to 92% of all internet-facing servers affected by the ProxyLogon vulnerabilities. The development, a 43% improvement from the previous week, caps off a whirlwind of espionage and malware campaigns that hit thousands of companies worldwide, with as many as 10 advanced persistent threat (APT) groups opportunistically moving quickly to exploit the bugs. According to telemetry data from RiskIQ, there are roughly 29,966 instances of Microsoft Exchange servers still exposed to attacks, down from 92,072 on March 10. While Exchange servers were under assault by multiple Chinese-linked state-sponsored hacking groups prior to  Microsoft's patch  on March 2, the release of  public proof-of-concept  exploits fanned a feeding frenzy of infections, opening the door for escalating attacks like ransomwar

Facebook may be banned in China, but the company on Wednesday said it has disrupted a network of bad actors using its platform to target the Uyghur community and lure them into downloading malicious software that would allow surveillance of their devices. "They targeted activists, journalists and dissidents predominantly among Uyghurs from Xinjiang in China primarily living abroad in Turkey, Kazakhstan, the United States, Syria, Australia, Canada and other countries," Facebook's Head of Cyber Espionage Investigations, Mike Dvilyanski, and Head of Security Policy, Nathaniel Gleicher,  said . "This group used various cyber espionage tactics to identify its targets and infect their devices with malware to enable surveillance." The social media giant said the "well-resourced and persistent operation" aligned with a threat actor known as  Evil Eye  (or Earth Empusa), a China-based collective known for its history of espionage attacks against the Muslim m

Purple Fox , a Windows malware previously known for infecting machines by using exploit kits and phishing emails, has now added a new technique to its arsenal that gives it worm-like propagation capabilities. The ongoing campaign makes use of a "novel spreading technique via indiscriminate port scanning and exploitation of exposed SMB services with weak passwords and hashes," according to  Guardicore researchers , who say the attacks have spiked by about 600% since May 2020. A total of 90,000 incidents have been spotted through the rest of 2020 and the beginning of 2021. First discovered in March 2018, Purple Fox is distributed in the form of malicious ".msi" payloads hosted on nearly 2,000 compromised Windows servers that, in turn, download and execute a component with  rootkit capabilities , which enables the threat actors to hide the malware on the machine and make it easy to evade detection. Guardicore says Purple Fox hasn't changed much post-exploitat

Google has disclosed that a now-patched vulnerability affecting Android devices that use Qualcomm chipsets is being weaponized by adversaries to launch targeted attacks. Tracked as CVE-2020-11261 (CVSS score 8.4), the flaw concerns an "improper input validation" issue in Qualcomm's Graphics component that could be exploited to trigger memory corruption when an attacker-engineered app requests access to a huge chunk of the device's memory. "There are indications that CVE-2020-11261 may be under limited, targeted exploitation," the search giant said in an updated January security bulletin on March 18. CVE-2020-11261 was discovered and reported to Qualcomm by Google's Android Security team on July 20, 2020, after which it was fixed in January 2021. It's worth noting that the access vector for the vulnerability is "local," meaning that exploitation requires local access to the device. In other words, to launch a successful attack, the

The U.S. Department of Justice yesterday announced updates on two separate cases involving cyberattacks—a Swiss hacktivist and a Russian hacker who planned to plant malware in the Tesla company. A Swiss hacker who was involved in the intrusion of cloud-based surveillance firm Verkada and exposed camera footage from its customers was charged by the U.S. Department of Justice (DoJ) on Thursday with conspiracy, wire fraud, and identity theft. Till Kottmann (aka "deletescape" and "tillie crimew"), 21, of Lucerne, Switzerland, and their co-conspirators were accused of hacking dozens of companies and government agencies since 2019 by targeting their "git" and other source code repositories and posting the proprietary data of more than 100 entities on a website called git[.]rip, according to the indictment. Kottmann is alleged to have cloned the source code and other confidential files containing hard-coded administrative credentials and access keys, using th

Cybersecurity researchers on Thursday disclosed a new attack wherein threat actors are leveraging Xcode as an attack vector to compromise Apple platform developers with a backdoor, adding to a growing trend that involves targeting developers and researchers with malicious attacks. Dubbed "XcodeSpy," the trojanized Xcode project is a tainted version of a legitimate, open-source project available on GitHub called TabBarInteraction that's used by developers to animate iOS tab bars based on user interaction. "XcodeSpy is a malicious Xcode project that installs a custom variant of the EggShell backdoor on the developer's macOS computer along with a persistence mechanism," SentinelOne researchers  said . Xcode is Apple's integrated development environment (IDE) for macOS, used to develop software for macOS, iOS, iPadOS, watchOS, and tvOS. Earlier this year, Google's Threat Analysis group  uncovered  a North Korean campaign aimed at security researche

Cybersecurity researchers on Monday disclosed a new wave of ongoing attacks exploiting multiple vulnerabilities to deploy new Mirai variants on internet connected devices. "Upon successful exploitation, the attackers try to download a malicious shell script, which contains further infection behaviors such as downloading and executing Mirai variants and brute-forcers," Palo Alto Networks' Unit 42 Threat Intelligence Team  said  in a write-up. The rash of vulnerabilities being exploited include: VisualDoor  - a SonicWall SSL-VPN remote command injection vulnerability that came to light earlier this January CVE-2020-25506  - a D-Link DNS-320 firewall remote code execution (RCE) vulnerability CVE-2021-27561 and CVE-2021-27562  - Two vulnerabilities in Yealink Device Management that allow an unauthenticated attacker to run arbitrary commands on the server with root privileges CVE-2021-22502  - an RCE flaw in Micro Focus Operation Bridge Reporter (OBR), affecting versio

Cybersecurity researchers have unwrapped an "interesting email campaign" undertaken by a threat actor that has taken to distributing a new malware written in  Nim  programming language. Dubbed " NimzaLoader " by Proofpoint researchers, the development marks one of the rare instances of Nim malware discovered in the threat landscape. "Malware developers may choose to use a rare programming language to avoid detection, as reverse engineers may not be familiar with Nim's implementation, or focused on developing detection for it, and therefore tools and sandboxes may struggle to analyze samples of it," the researchers said. Proofpoint is tracking the operators of the campaign under the moniker "TA800," who, they say, started distributing NimzaLoader starting February 3, 2021. Prior to the latest raft of activity, TA800 is known to have predominantly used BazaLoader since April 2020. While APT28 has been previously linked to delivering  Zeb

It didn't take long. Intelligence agencies and cybersecurity researchers had been warning that unpatched Exchange Servers could open the pathway for ransomware infections in the wake of swift escalation of the attacks since last week. Now it appears that threat actors have caught up.  According to the latest reports , cybercriminals are leveraging the heavily exploited ProxyLogon Exchange Server flaws to install a new strain of ransomware called "DearCry." "Microsoft observed a new family of human operated ransomware attack customers – detected as Ransom:Win32/DoejoCrypt.A," Microsoft researcher Phillip Misner  tweeted . "Human operated ransomware attacks are utilizing the Microsoft Exchange vulnerabilities to exploit customers." Microsoft's security intelligence team, in a separate tweet,  confirmed  that it has begun "blocking a new family of ransomware being used after an initial compromise of unpatched on-premises Exchange Servers.&q

Application security company F5 Networks on Wednesday published an  advisory  warning of four critical vulnerabilities impacting multiple products that could result in a denial of service (DoS) attack and even unauthenticated remote code execution on target networks. The patches concern a total of seven related flaws (from CVE-2021-22986 through CVE-2021-22992),  two  of  which  were discovered and reported by Felix Wilhelm of Google Project Zero in December 2020. The four critical flaws affect BIG-IP versions 11.6 or 12.x and newer, with a critical pre-auth remote code execution (CVE-2021-22986) also affecting BIG-IQ versions 6.x and 7.x. F5 said it's not aware of any public exploitation of these issues. Successful exploitation of these vulnerabilities could lead to a full compromise of vulnerable systems, including the possibility of remote code execution as well as trigger a buffer overflow, leading to a DoS attack. Urging customers to update their BIG-IP and BIG-IQ deploy

Cybersecurity researchers on Wednesday shed light on a new sophisticated backdoor targeting Linux endpoints and servers that's believed to be the work of Chinese nation-state actors. Dubbed " RedXOR " by Intezer, the backdoor masquerades as a polkit daemon, with similarities found between the malware and those previously associated with the  Winnti Umbrella  (or Axiom) threat group such as ​PWNLNX, ​XOR.DDOS​ and Groundhog. RedXOR's name comes from the fact that it encodes its network data with a scheme based on XOR, and that it's compiled with a legacy  GCC compiler  on an old release of Red Hat Enterprise Linux, suggesting that the malware is deployed in targeted attacks against legacy Linux systems. Intezer said  two   samples  of the malware were uploaded from Indonesia and Taiwan around Feb. 23-24, both countries that are known to be singled out by China-based threat groups. Aside from the overlaps in terms of the overall flow and functionalities and th

Threat actors known for keeping a low profile do so by ceasing operations for prolonged periods in between to evade attracting any attention as well as constantly refining their toolsets to fly below the radar of many detection technologies. One such group is  FIN8 , a financially motivated threat actor that's back in action after a year-and-a-half hiatus with a powerful version of a backdoor with upgraded capabilities including screen capturing, proxy tunneling, credential theft, and  fileless execution . First documented in 2016 by FireEye, FIN8 is known for its attacks against the retail, hospitality, and entertainment industries while making use of a wide array of techniques such as spear-phishing and malicious tools like  PUNCHTRACK  and  BADHATCH  to steal payment card data from point-of-sale (POS) systems. "The FIN8 group is known for taking long breaks to improve  TTPs  and increase their rate of success," Bitdefender researchers  said  in a report published
