As many as 55 zero-day vulnerabilities were exploited in the wild in 2022, with most of the flaws discovered in software from Microsoft, Google, and Apple. While this figure represents a decrease from the year before, when a staggering 81 zero-days were weaponized, it still represents a significant uptick in recent years of threat actors leveraging unknown security flaws to their advantage. The  findings  come from threat intelligence firm Mandiant, which noted that desktop operating systems (19), web browsers (11), IT and network management products (10), and mobile operating systems (six) accounted for the most exploited product types. Of the 55 zero-day bugs, 13 are estimated to have been abused by cyber espionage groups, with four others exploited by financially motivated threat actors for ransomware-related operations. Commercial spyware vendors were linked to the exploitation of three zero-days. Among state-sponsored groups, those attributed to China have emerged as the most

Bitcoin ATM maker General Bytes disclosed that unidentified threat actors stole cryptocurrency from hot wallets by exploiting a zero-day security flaw in its software. "The attacker was able to upload his own java application remotely via the master service interface used by terminals to upload videos and run it using 'batm' user privileges," the company  said  in an advisory published over the weekend. "The attacker scanned the Digital Ocean cloud hosting IP address space and identified running CAS services on ports 7741, including the General Bytes Cloud service and other GB ATM operators running their servers on Digital Ocean," it further added. The company said that the server to which the malicious Java application was uploaded was by default configured to start applications present in the deployment folder ("/batm/app/admin/standalone/deployments/"). In doing so, the attack allowed the threat actor to access the database; read and decry

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

A new piece of malware dubbed  dotRunpeX  is being used to distribute numerous known malware families such as  Agent Tesla ,  Ave Maria ,  BitRAT ,  FormBook ,  LokiBot ,  NetWire ,  Raccoon Stealer ,  RedLine Stealer ,  Remcos ,  Rhadamanthys , and  Vidar . "DotRunpeX is a new injector written in .NET using the Process Hollowing technique and used to infect systems with a variety of known malware families," Check Point  said  in a report published last week. Said to be in active development, dotRunpeX arrives as a second-stage malware in the infection chain, often deployed via a downloader (aka loader) that's transmitted through phishing emails as malicious attachments. Alternatively, it's known to leverage malicious Google Ads on search result pages to direct unsuspecting users searching for popular software such as AnyDesk and LastPass to copycat sites hosting trojanized installers. The latest DotRunpeX artifacts, first spotted in October 2022, add an extra o

A banking trojan dubbed  Mispadu  has been linked to multiple spam campaigns targeting countries like Bolivia, Chile, Mexico, Peru, and Portugal with the goal of stealing credentials and delivering other payloads. The activity, which commenced in August 2022, is currently ongoing, the Ocelot Team from Latin American cybersecurity firm Metabase Q said in a report shared with The Hacker News. Mispadu  (aka URSA) was  first documented  by ESET in November 2019, describing its ability to perpetrate monetary and credential theft and act as a backdoor by taking screenshots and capturing keystrokes. "One of their main strategies is to compromise legitimate websites, searching for vulnerable versions of WordPress, to turn them into their command-and-control server to spread malware from there, filtering out countries they do not wish to infect, dropping different type of malware based on the country being infected," researchers Fernando García and Dan Regalado said. It's a

2022 was the year when inflation hit world economies, except in one corner of the global marketplace – stolen data. Ransomware payments fell by over 40% in 2022 compared to 2021. More organisations chose not to pay ransom demands, according to findings by blockchain firm Chainalysis. Nonetheless, stolen data has value beyond a price tag, and in risky ways you may not expect. Evaluating stolen records is what  Lab 1, a new cyber monitoring platform , believes will make a big difference for long-term cybersecurity resilience. Think of data value this way:  Stolen credentials can become future phishing attacks Logins for adult websites are potential extortion attempts Travel and location data are a risk to VIPs and senior leadership, And so on… Hackers could retaliate for non-payment by simply posting their loot to forums where the data will be available for further enrichment and exploitation.  Shining a light on dark places Even though your company may not have suffered a di

The threat actors behind the CatB ransomware operation have been observed using a technique called  DLL search order hijacking  to evade detection and launch the payload. CatB, also referred to as CatB99 and Baxtoy, emerged late last year and is said to be an "evolution or direct rebrand" of another ransomware strain known as Pandora based on code-level similarities. It's worth noting that the use of Pandora has been attributed to  Bronze Starlight  (aka DEV-0401 or Emperor Dragonfly), a China-based threat actor that's known to employ  short-lived ransomware families  as a ruse to likely conceal its true objectives.  One of the key defining characteristics of CatB is its reliance on DLL hijacking via a legitimate service called Microsoft Distributed Transaction Coordinator ( MSDTC ) to extract and launch the ransomware payload. "Upon execution, CatB payloads rely on DLL search order hijacking to drop and load the malicious payload," SentinelOne researc

The notorious Emotet malware, in its  return after a short hiatus , is now being distributed via  Microsoft OneNote email attachments  in an attempt to bypass macro-based security restrictions and compromise systems. Emotet , linked to a threat actor tracked as Gold Crestwood, Mummy Spider, or TA542, continues to be a potent and resilient threat despite attempts by law enforcement to take it down. A  derivative  of the  Cridex   banking worm  – which was  subsequently   replaced  by  Dridex  around the same time GameOver Zeus was disrupted in 2014 – Emotet has  evolved  into a "monetized platform for other threat actors to run malicious campaigns on a pay-per-install (PPI) model, allowing theft of sensitive data and ransom extortion." While Emotet infections have acted as a  conduit  to deliver Cobalt Strike, IcedID, Qakbot, Quantum ransomware, and TrickBot, its return in late 2021 was  facilitated  by means of TrickBot. "Emotet is known for extended periods of ina

The zero-day exploitation of a now-patched medium-severity security flaw in the Fortinet  FortiOS  operating system has been linked to a suspected Chinese hacking group. American cybersecurity company Mandiant, which made the attribution, said the activity cluster is part of a broader campaign designed to deploy backdoors onto Fortinet and VMware solutions and maintain persistent access to victim environments. The Google-owned threat intelligence and incident response firm is tracking the malicious operation under its uncategorized moniker UNC3886 , describing it as a China-nexus threat actor. "UNC3886 is an advanced cyber espionage group with unique capabilities in how they operate on-network as well as the tools they utilize in their campaigns," Mandiant researchers  said  in a technical analysis. "UNC3886 has been observed targeting firewall and virtualization technologies which lack EDR support. Their ability to manipulate firewall firmware and exploit a zero-da

U.S. law enforcement authorities have arrested a 21-year-old New York man in connection with running the infamous BreachForums hacking forum under the online alias " Pompompurin ." The development, first reported by  Bloomberg Law , comes after News 12 Westchester, earlier this week, said that federal investigators "spent hours inside and outside of a home in Peekskill." "At one point, investigators were seen removing several bags of evidence from the house," the New York-based local news service  added . According  to an  affidavit  filed by the Federal Bureau of Investigation (FBI), the suspect identified himself as Conor Brian Fitzpatrick and admitted to being the owner of the BreachForums website. "When I arrested the defendant on March 15, 2023, he stated to me in substance and in part that: a) his name was Conor Brian Fitzpatrick; b) he used the alias 'pompompurin,' and c) he was the owner and administrator of 'BreachForums,&#

U.S. government agencies have released a joint cybersecurity advisory detailing the indicators of compromise (IoCs) and tactics, techniques, and procedures (TTPs) associated with the notorious  LockBit 3.0 ransomware . "The LockBit 3.0 ransomware operations function as a Ransomware-as-a-Service (RaaS) model and is a continuation of previous versions of the ransomware, LockBit 2.0, and LockBit," the authorities  said . The alert comes courtesy of the U.S. Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), and the Multi-State Information Sharing & Analysis Center (MS-ISAC). Since emerging in late 2019, the  LockBit actors  have invested significant  technical efforts  to develop and fine-tune its malware, issuing two major updates — LockBit 2.0, released in mid-2021, and  LockBit 3.0 , released in June 2022. The two versions are also known as LockBit Red and LockBit Black, respectively. "LockBit 3.0 accepts addition

An Android voice phishing (aka vishing) malware campaign known as FakeCalls has reared its head once again to target South Korean users under the guise of over 20 popular financial apps. "FakeCalls malware possesses the functionality of a Swiss army knife, able not only to conduct its primary aim but also to extract private data from the victim's device," cybersecurity firm Check Point said . FakeCalls was previously documented by Kaspersky in April 2022, describing the malware's capabilities to imitate phone conversations with a bank customer support agent. In the observed attacks, users who install the rogue banking app are enticed into calling the financial institution by offering a fake low-interest loan. At the point where the phone call actually happens, a pre-recorded audio with instructions from the real bank is played. Simultaneously, the malware conceals the phone number with the bank's legitimate number to give the impression that a conversation

A new Golang-based botnet dubbed  HinataBot  has been observed to leverage known flaws to compromise routers and servers and use them to stage distributed denial-of-service (DDoS) attacks. "The malware binaries appear to have been named by the malware author after a character from the popular anime series, Naruto, with file name structures such as 'Hinata-<OS>-<Architecture>,'" Akamai  said  in a technical report. Among the methods used to distribute the malware are the exploitation of exposed Hadoop YARN servers and security flaws in Realtek SDK devices ( CVE-2014-8361 )and Huawei HG532 routers ( CVE-2017-17215 , CVSS score: 8.8). Unpatched vulnerabilities and weak credentials have been a low-hanging fruit for attackers, representing an easy, well-documented entry point that does not require sophisticated social engineering tactics or other methods. The threat actors behind HinataBot are said to have been active since at least December 2022, with the

In the modern corporate IT environment, which relies on cloud connectivity, global connections and large volumes of data, the browser is now the most important work interface. The browser connects employees to managed resources, devices to the web, and the on-prem environment to the cloud one. Yet, and probably unsurprisingly, this browser prominence has significantly increased the number of threats that adversaries target the browser with. Attackers are now leveraging the browser's core functionality - rendering and executing web pages for users to access - to perform attacks. The browser is now an attack surface, as well as an attack vector for malicious access to corporate SaaS and web applications through account takeover and the use of compromised credentials. To address this issue, a new guide was recently published ( Download Here ). It analyzes what a solution to these threats would look like. The guide, "Protection from web-borne threats starts with Browser Securit

Copycat websites for instant messaging apps like Telegram and WhatApp are being used to distribute trojanized versions and infect Android and Windows users with cryptocurrency clipper malware . "All of them are after victims' cryptocurrency funds, with several targeting cryptocurrency wallets," ESET researchers Lukáš Štefanko and Peter Strýček said in a new analysis. While the first instance of clipper malware on the Google Play Store dates back to 2019, the development marks the first time Android-based clipper malware has been built into instant messaging apps. "Moreover, some of these apps use optical character recognition (OCR) to recognize text from screenshots stored on the compromised devices, which is another first for Android malware," the Slovak cybersecurity firm added. The attack chain begins with unsuspecting users clicking on fraudulent ads on Google search results that lead to hundreds of sketchy YouTube channels, which then direct them

The advanced persistent threat known as  Winter Vivern  has been linked to campaigns targeting government officials in India, Lithuania, Slovakia, and the Vatican since 2021. The activity targeted Polish government agencies, the Ukraine Ministry of Foreign Affairs, the Italy Ministry of Foreign Affairs, and individuals within the Indian government, SentinelOne said in a report shared with The Hacker News. "Of particular interest is the APT's targeting of private businesses, including telecommunications organizations that support Ukraine in the ongoing war," senior threat researcher Tom Hegel  said . Winter Vivern, also tracked as UAC-0114,  drew attention  last month after the Computer Emergency Response Team of Ukraine (CERT-UA) detailed a new malware campaign aimed at state authorities of Ukraine and Poland to deliver a piece of malware dubbed Aperetif. Previous public reports chronicling the group show that it has leveraged weaponized Microsoft Excel documents con
