Microsoft on Monday revealed new malware deployed by the hacking group behind the SolarWinds supply chain attack last December to deliver additional payloads and steal sensitive information from Active Directory Federation Services ( AD FS ) servers. The tech giant's Threat Intelligence Center (MSTIC) codenamed the "passive and highly targeted backdoor" FoggyWeb, making it the threat actor tracked as Nobelium's latest tool in a long list of cyber weaponry such as  Sunburst ,  Sunspot ,  Raindrop ,  Teardrop ,  GoldMax, GoldFinder, Sibot ,  Flipflop ,  NativeZone ,  EnvyScout, BoomBox, and VaporRage . "Once Nobelium obtains credentials and successfully compromises a server, the actor relies on that access to maintain persistence and deepen its infiltration using sophisticated malware and tools," MSTIC researchers  said . "Nobelium uses FoggyWeb to remotely exfiltrate the configuration database of compromised AD FS servers, decrypted token-...

State-sponsored hackers affiliated with Russia are behind a new series of intrusions using a previously undocumented implant to compromise systems in the U.S., Germany, and Afghanistan. Cisco Talos attributed the attacks to the  Turla  advanced persistent threat (APT) group, coining the malware "TinyTurla" for its limited functionality and efficient coding style that allows it to go undetected. Attacks incorporating the backdoor are believed to have occurred since 2020. "This simple backdoor is likely used as a second-chance backdoor to maintain access to the system, even if the primary malware is removed," the researchers  said . "It could also be used as a second-stage dropper to infect the system with additional malware." Furthermore, TinyTurla can upload and execute files or exfiltrate sensitive data from the infected machine to a remote server, while also polling the command-and-control (C2) station every five seconds for any new commands. Also k...

The operators behind the BlackRock mobile malware have surfaced back with a new Android banking trojan called  ERMAC  that targets Poland and has its roots in the infamous Cerberus malware, according to the latest research. "The new trojan already has active distribution campaigns and is targeting 378 banking and wallet apps with overlays," ThreatFabric's CEO Cengiz Han Sahin said in an emailed statement. First campaigns involving ERMAC are believed to have begun in late August under the guise of the Google Chrome app. Since then, the attacks have expanded to include a range of apps such as banking, media players, delivery services, government applications, and antivirus solutions like  McAfee . Almost fully based on the notorious banking trojan  Cerberus , the Dutch cybersecurity firm's findings come from forum posts made by an actor named DukeEugene last month on August 17, inviting prospective customers to "rent a new android botnet with wide functionalit...

DMARC  is a global standard for email authentication. It allows senders to verify that the email really comes from whom it claims to come from. This helps curb spam and phishing attacks, which are among the most prevalent cybercrimes of today. Gmail, Yahoo, and many other large email providers have implemented DMARC and praised its benefits in recent years. If your company's domain name is bankofamerica.com, you do not want a cyber attacker to be able to send emails under that domain. This puts your brand reputation at risk and could potentially spread financial malware. The DMARC standard prevents this by checking whether emails are sent from an expected IP address or domain. It specifies how domains can be contacted if there are authentication or migration issues and provides forensic information so senders can monitor email traffic and quarantine suspicious emails. What is a Phishing Attack? Phishing is an attempt by cybercriminals to trick victims into giving away sensitive...

Cybersecurity researchers have charted the evolution of Jupyter, a .NET infostealer known for singling out healthcare and education sectors, which make it exceptional at defeating most endpoint security scanning solutions. The new delivery chain, spotted by  Morphisec  on September 8, underscores that the malware has not just continued to remain active but also showcases "how threat actors continue to develop their attacks to become more efficient and evasive." The Israeli company said it's currently investigating the scale and scope of the attacks. First  documented  in November 2020, Jupyter (aka Solarmarker) is likely Russian in origin and primarily targets Chromium, Firefox, and Chrome browser data, with additional capabilities that allow for full backdoor functionality, including features to siphon information and upload the details to a remote server and download and execute further payloads. Forensic evidence gathered by Morphisec shows that multiple versi...

Google on Friday rolled out an emergency security patch to its Chrome web browser to address a security flaw that's known to have an exploit in the wild. Tracked as  CVE-2021-37973 , the vulnerability has been described as  use after free  in  Portals API , a web page navigation system that enables a page to show another page as an inset and "perform a seamless transition to a new state, where the formerly-inset page becomes the top-level document." Clément Lecigne of Google Threat Analysis Group (TAG) has been credited with reporting the flaw. Additional specifics pertaining to the weakness have not been disclosed in light of active exploitation and to allow a majority of the users to apply the patch, but the internet giant said it's "aware that an exploit for CVE-2021-37973 exists in the wild." The update arrives a day after Apple moved to close an actively exploited security hole in older versions of iOS and macOS ( CVE-2021-30869 ), which the TAG no...

Network security company SonicWall has addressed a critical security vulnerability affecting its Secure Mobile Access (SMA) 100 series appliances that can permit remote, unauthenticated attackers to gain administrator access on targeted devices remotely. Tracked as  CVE-2021-20034 , the arbitrary file deletion flaw is rated 9.1 out of a maximum of 10 on the CVSS scoring system, and could allow an adversary to bypass path traversal checks and delete any file, causing the devices to reboot to factory default settings. "The vulnerability is due to an improper limitation of a file path to a restricted directory potentially leading to arbitrary file deletion as 'nobody,'" the San Jose-based firm  noted  in an advisory published Thursday. "There is no evidence that this vulnerability is being exploited in the wild." SonicWall credited Wenxu Yin of Alpha Lab, Qihoo 360, with reporting the security shortcoming, which impacts SMA 100 Series — SMA 200, SMA 210, ...
