Kaseya Issues Patches for Two New 0-Day Flaws Affecting Unitrends Servers

August 27, 2021Ravie Lakshmanan
U.S. technology firm Kaseya has  released  security patches to address two zero-day vulnerabilities affecting its Unitrends enterprise backup and continuity solution that could result in privilege escalation and authenticated remote code execution. The two weaknesses are part of a  trio of vulnerabilities  discovered and reported by researchers at the Dutch Institute for Vulnerability Disclosure (DIVD) on July 3, 2021. The IT infrastructure management solution provider has addressed the issues in server software version 10.5.5-2 released on August 12, DIVD said. An as-yet-undisclosed client-side vulnerability in Kaseya Unitrends remains unpatched, but the company has published  firewall rules  that can be applied to filter traffic to and from the client and mitigate any risk associated with the flaw. As an additional precaution, it's  recommended  not to leave the servers accessible over the internet. Although specifics related to the vulnerabilities are sparse, the shortcomin

Researchers Uncover FIN8's New Backdoor Targeting Financial Institutions

August 25, 2021Ravie Lakshmanan
A financially motivated threat actor notorious for setting its sights on retail, hospitality, and entertainment industries has been observed deploying a completely new backdoor on infected systems, indicating the operators are continuously retooling their malware arsenal to avoid detection and stay under the radar. The previously undocumented malware has been dubbed " Sardonic " by Romanian cybersecurity technology company Bitdefender, which it encountered during a  forensic investigation  in the wake of an unsuccessful attack carried out by FIN8 aimed at an unnamed financial institution located in the U.S. Said to be under active development, "Sardonic backdoor is extremely potent and has a wide range of capabilities that help the threat actor leverage new malware on the fly without updating components," Bitdefender researchers Eduard Budaca and Victor Vrabie said in a report shared with The Hacker News. Since emerging on the scene in January 2016, FIN8 has
B. Braun Infusomat Pumps Could Let Attackers Remotely Alter Medication Dosages

B. Braun Infusomat Pumps Could Let Attackers Remotely Alter Medication Dosages

August 25, 2021Ravie Lakshmanan
Cybersecurity researchers have disclosed five previously unreported security vulnerabilities affecting B. Braun's Infusomat Space Large Volume Pump and SpaceStation that could be abused by malicious parties to tamper with medication doses without any prior authentication. McAfee, which discovered and reported the flaws to the German medical and pharmaceutical device company on January 11, 2021,  said  the "modification could appear as a device malfunction and be noticed only after a substantial amount of drug has been dispensed to a patient, since the infusion pump displays exactly what was prescribed, all while dispensing potentially lethal doses of medication." The issues have been addressed by B. Braun in SpaceCom L82 or later, Battery Pack SP with WiFi:L82 or later, and DataModule compactplus version A12 or later. Infusion pumps are medical devices used to deliver intravenous fluids, such as nutrients and medications, into a patient's body in controlled amoun

Researchers Warn of 4 Emerging Ransomware Groups That Can Cause Havoc

August 24, 2021Ravie Lakshmanan
Cybersecurity researchers on Tuesday took the wraps off four up-and-coming ransomware groups that could pose a serious threat to enterprises and critical infrastructure, as the ripple effect of a recent spurt in ransomware incidents show that attackers are growing more sophisticated and more profitable in extracting payouts from victims. "While the ransomware crisis appears poised to get worse before it gets better, the cast of cybercrime groups that cause the most damage is constantly changing," Palo Alto Networks' Unit 42 threat intelligence team  said  in a report shared with The Hacker News. "Groups sometimes go quiet when they've achieved so much notoriety that they become a priority for law enforcement. Others reboot their operations to make them more lucrative by revising their tactics, techniques and procedures, updating their software and launching marketing campaigns to recruit new affiliates." The development comes as ransomware attacks are g

Researchers Detail Modus Operandi of ShinyHunters Cyber Crime Group

August 23, 2021Ravie Lakshmanan
ShinyHunters, a notorious cybercriminal underground group that's been on a data breach spree since last year, has been observed searching companies' GitHub repository source code for vulnerabilities that can be abused to stage larger scale attacks, an analysis of the hackers' modus operandi has revealed. "Primarily operating on Raid Forums, the collective's moniker and motivation can partly be derived from their avatar on social media and other forums: a shiny Umbreon Pokémon," Intel 471 researchers said in a report shared with The Hacker News. "As Pokémon players hunt and collect "shiny" characters in the game, ShinyHunters collects and resells user data." The revelation comes as the  average cost of a data breach  rose from $3.86 million to $4.24 million, making it the highest average cost in 17 years, with compromised credentials responsible for 20% of the breaches reported by over 500 organizations. Since rising to prominence in A

Cloudflare mitigated one of the largest DDoS attack involving 17.2 million rps

August 20, 2021Ravie Lakshmanan
Web infrastructure and website security company Cloudflare on Thursday disclosed that it mitigated the largest ever volumetric distributed denial of service (DDoS) attack recorded to date. The attack, launched via a Mirai botnet, is said to have targeted an unnamed customer in the financial industry last month. "Within seconds, the botnet bombarded the Cloudflare edge with over 330 million attack requests," the company  noted , at one point reaching a record high of 17.2 million requests-per-second (rps), making it three times bigger than previously reported HTTP DDoS attacks. Volumetric DDoS attacks are designed to target a specific network with an intention to overwhelm its bandwidth capacity and often utilize  reflective amplification techniques  to scale their attack and cause as much operational disruption as possible. They also typically originate from a network of malware-infected systems — consisting of computers, servers, and IoT devices — enabling threat actors
Researchers Find New Evidence Linking Diavol Ransomware to TrickBot Gang

Researchers Find New Evidence Linking Diavol Ransomware to TrickBot Gang

August 19, 2021Ravie Lakshmanan
Cybersecurity researchers have disclosed details about an early development version of a nascent ransomware strain called Diavol that has been linked to threat actors behind the infamous TrickBot syndicate. The latest  findings  from IBM X-Force show that the ransomware sample shares similarities to other malware that has been attributed to the cybercrime gang, thus establishing a clearer connection between the two. In early July, Fortinet  revealed  specifics of an unsuccessful ransomware attack involving Diavol payload targeting one of its customers, highlighting the malware's source code overlaps with that of Conti and its technique of reusing some language from Egregor ransomware in its ransom note. "As part of a rather unique encryption procedure, Diavol operates using user-mode Asynchronous Procedure Calls (APCs) without a symmetric encryption algorithm," Fortinet researchers previously said. "Usually, ransomware authors aim to complete the encryption oper

NK Hackers Deploy Browser Exploits on South Korean Sites to Spread Malware

August 18, 2021Ravie Lakshmanan
A North Korean threat actor has been discovered taking advantage of two exploits in Internet Explorer to infect victims with a custom implant as part of a strategic web compromise (SWC) targeting a South Korean online newspaper. Cybersecurity firm Volexity  attributed  the watering hole attacks to a threat actor it tracks as InkySquid, and more widely known by the monikers ScarCruft and APT37. Daily NK, the publication in question, is said to have hosted the malicious code from at least late March 2021 until early June 2021. The "clever disguise of exploit code amongst legitimate code" and the use of custom malware enables the attackers to avoid detection, Volexity researchers said. The attacks involved tampering with the jQuery JavaScript libraries hosted on the website to serve additional obfuscated JavaScript code from a remote URL, using it to leverage exploits for two Internet Explorer flaws that were patched by Microsoft in  August 2020  and  March 2021 .

Attackers Can Weaponize Firewalls and Middleboxes for Amplified DDoS Attacks

Attackers Can Weaponize Firewalls and Middleboxes for Amplified DDoS Attacks

August 16, 2021Ravie Lakshmanan
Weaknesses in the implementation of TCP protocol in  middleboxes  and censorship infrastructure could be weaponized as a vector to stage reflected denial of service (DoS) amplification attacks against any target, surpassing many of the existing UDP-based amplification factors to date. Detailed by a group of academics from the University of Maryland and the University of Colorado Boulder at the USENIX Security Symposium, the volumetric attacks take advantage of TCP-non-compliance in-network middleboxes — such as firewalls, intrusion prevention systems, and deep packet inspection (DPI) boxes — to amplify network traffic, with hundreds of thousands of IP addresses offering  amplification factors  exceeding those from DNS, NTP, and Memcached. The research, which received a Distinguished Paper Award at the conference, is the first of its kind to describe a technique to carry out DDoS reflected amplification attacks over the TCP protocol by abusing middlebox misconfigurations in the wild

Experts Shed Light On New Russian Malware-as-a-Service Written in Rust

August 12, 2021Ravie Lakshmanan
A nascent information-stealing malware sold and distributed on underground Russian underground forums has been written in Rust, signalling a new trend where threat actors are increasingly adopting  exotic programming languages  to bypass security protections, evade analysis, and hamper reverse engineering efforts. Dubbed " Ficker Stealer ," it's notable for being propagated via Trojanized web links and compromised websites, luring in victims to scam landing pages purportedly offering free downloads of  legitimate paid services  like Spotify Music, YouTube Premium, and other Microsoft Store applications. "Ficker is sold and distributed as Malware-as-a-Service (MaaS), via underground Russian online forums," BlackBerry's research and intelligence team said in a report published today. "Its creator, whose alias is @ficker, offers several paid packages, with different levels of subscription fees to use their malicious program." First seen in the wi

How Companies Can Protect Themselves from Password Spraying Attacks

August 12, 2021The Hacker News
Attackers are using many types of attacks to compromise business-critical data. These can include zero-day attacks, supply chain attacks, and others. However, one of the most common ways that hackers get into your environment is by compromising passwords. The password spraying attack is a special kind of password attack that can prove effective in compromising your environment. Let's look closer at the password spraying attack and how organizations can prevent it. Beware of compromised credentials Are compromised credentials dangerous to your environment? Yes! Compromised credentials allow an attacker to "walk in the front door" of your environment with legitimate credentials. They assume all the rights and permissions to systems, data, and resources the compromised account can access. The compromise of a privileged account is even worse. Privileged accounts are accounts that have high levels of access, such as an administrator user account. These types of accounts r

Beware! New Android Malware Hacks Thousands of Facebook Accounts

August 09, 2021Ravie Lakshmanan
A new Android trojan has been found to compromise Facebook accounts of over 10,000 users in at least 144 countries since March 2021 via fraudulent apps distributed through Google Play Store and other third-party app marketplaces. Dubbed " FlyTrap ," the previously undocumented malware is believed to be part of a family of trojans that employ social engineering tricks to breach Facebook accounts as part of a session hijacking campaign orchestrated by malicious actors operating out of Vietnam, according to a  report  published by Zimperium's zLabs today and shared with The Hacker News. Although the offending nine applications have since been pulled from Google Play, they continue to be available in third-party app stores, "highlighting the risk of sideloaded applications to mobile endpoints and user data," Zimperium malware researcher Aazim Yaswant said. The list of apps is as follows - GG Voucher (com.luxcarad.cardid)  Vote European Football (com.gardengu

New APT Hacking Group Targets Microsoft IIS Servers with ASP.NET Exploits

August 02, 2021Ravie Lakshmanan
A new highly capable and persistent threat actor has been targeting major high-profile public and private entities in the U.S. as part of a series of targeted cyber intrusion attacks by exploiting internet-facing Microsoft Internet Information Services ( IIS ) servers to infiltrate their networks. Israeli cybersecurity firm Sygnia, which identified the campaign, is tracking the advanced, stealthy adversary under the moniker "Praying Mantis" or "TG2021." "TG1021 uses a custom-made malware framework, built around a common core, tailor-made for IIS servers. The toolset is completely volatile, reflectively loaded into an affected machine's memory and leaves little-to-no trace on infected targets," the researchers  said . "The threat actor also uses an additional stealthy backdoor and several post-exploitations modules to perform network reconnaissance, elevate privileges, and move laterally within networks."  Besides exhibiting capabilities

Solarmarker InfoStealer Malware Once Again Making its Way Into the Wild

August 02, 2021Ravie Lakshmanan
Healthcare and education sectors are the frequent targets of a new surge in credential harvesting activity from what's a "highly modular" .NET-based information stealer and keylogger, charting the course for the threat actor's continued evolution while simultaneously remaining under the radar. Dubbed " Solarmarker ," the malware campaign is believed to be active since September 2020, with telemetry data pointing to malicious actions as early as April 2020, according to Cisco Talos. "At its core, the Solarmarker campaign appears to be conducted by a fairly sophisticated actor largely focused on credential and residual information theft," Talos researchers Andrew Windsor and Chris Neal  said  in a technical write-up published last week. Infections consist of multiple moving parts, chief among them being a .NET assembly module that serves as a system profiler and staging ground on the victim host for command-and-control (C2) communications and fur

Experts Uncover Several C&C Servers Linked to WellMess Malware

July 30, 2021Ravie Lakshmanan
Cybersecurity researchers on Friday unmasked new command-and-control (C2) infrastructure belonging to the Russian threat actor tracked as APT29, aka Cozy Bear, that has been spotted actively serving WellMess malware as part of an ongoing attack campaign. More than 30 C2 servers operated by the Russian foreign intelligence have been uncovered, Microsoft-owned cybersecurity subsidiary RiskIQ  said  in a report shared with The Hacker News. APT29, the moniker assigned to government operatives working for Russia's Foreign Intelligence Service (SVR), is believed to have been the  mastermind behind the massive SolarWinds supply chain attack  that came to light late last year, with the U.K. and U.S. governments formally pinning the intrusions on Russia earlier this April. The activity is being tracked by the cybersecurity community under various codenames, including UNC2452 (FireEye), Nobelium (Microsoft), SolarStorm (Unit 42), StellarParticle (Crowdstrike), Dark Halo (Volexity), and
