Google is calling attention to a set of severe security flaws in Samsung's Exynos chips, some of which could be exploited remotely to completely compromise a phone without requiring any user interaction. The 18 zero-day vulnerabilities affect a wide range of Android smartphones from Samsung, Vivo, Google, wearables using the Exynos W920 chipset, and vehicles equipped with the Exynos Auto T5123 chipset. Four of the 18 flaws make it possible for a threat actor to achieve internet-to-Samsung, Vivo, and Google, as well as wearables using the Exynos W920 chipset and vehicleses in late 2022 and early 2023, said. "[The] four vulnerabilities allow an attacker to remotely compromise a phone at the baseband level with no user interaction, and require only that the attacker know the victim's phone number," Tim Willis, head of Google Project Zero,  said . In doing so, a threat actor could gain entrenched access to cellular information passing in and out of the targeted devi

Threat activity clusters affiliated with the Chinese and Russian cybercriminal ecosystems have been observed using a new piece of malware that's designed to load Cobalt Strike onto infected machines. Dubbed  SILKLOADER  by Finnish cybersecurity company WithSecure, the malware leverages  DLL side-loading techniques  to deliver the commercial adversary simulation software. The development comes as  improved detection capabilities  against Cobalt Strike, a legitimate post-exploitation tool used for red team operations, is forcing threat actors to  seek alternative options  or concoct new ways to propagate the framework to evade detection. "The most common of these include adding complexity to the auto-generated beacon or stager payloads via the utilization of packers, crypters, loaders, or similar techniques," WithSecure researchers  said . SILKLOADER joins other loaders such as KoboldLoader, MagnetLoader, and LithiumLoader that have been  recently discovered  incorpora

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,

The cryptojacking group known as  TeamTNT  is suspected to be behind a previously undiscovered strain of malware used to mine Monero cryptocurrency on compromised systems. That's according to Cado Security, which  found  the  sample  after Sysdig detailed a sophisticated attack known as  SCARLETEEL  aimed at containerized environments to ultimately steal proprietary data and software. Specifically, the early phase of the attack chain involved the use of a cryptocurrency miner, which the cloud security firm suspected was deployed as a decoy to conceal the detection of data exfiltration. The artifact – uploaded to VirusTotal late last month – "bear[s] several syntactic and semantic similarities to prior TeamTNT payloads, and includes a wallet ID that has previously been attributed to them," a new analysis from Cado Security has  revealed . TeamTNT , active since at least 2019, has been documented to repeatedly strike cloud and container environments to deploy cryptocur

A coalition of law enforcement agencies across Europe and the U.S.  announced  the takedown of ChipMixer, an unlicensed cryptocurrency mixer that began its operations in August 2017. "The ChipMixer software blocked the blockchain trail of the funds, making it attractive for cybercriminals looking to launder illegal proceeds from criminal activities such as drug trafficking, weapons trafficking, ransomware attacks, and payment card fraud," Europol  said  in a statement. The coordinated exercise, besides dismantling the clearnet and dark web websites associated with ChipMixer, also resulted in the seizure of $47.5 million in Bitcoin and 7 TB of data. Mixers, also called tumblers,  offer full anonymity  for a fee by commingling cryptocurrency from different users – both legitimate and criminally-derived funds – in a manner that makes it hard to trace the origins. This is achieved by funneling different payments into a single pool before splitting up each amount and transmit

In last year's edition of the  Security Navigator  we noted that the Manufacturing Industry appeared to be totally over-represented in our dataset of Cyber Extortion victims. Neither the number of businesses nor their average revenue particularly stood out to explain this. Manufacturing was also the most represented Industry in our CyberSOC dataset – contributing more Incidents than any other sector.  We found this trend confirmed in 2023 – so much in fact that we decided to take a closer look. So let's examine some possible explanations.  And debunk them. Hunting for possible explanations Manufacturing is still the most impacted industry in our Cyber Extortion dataset in 2023, as tracked by monitoring double-extortion leak sites. Indeed, this sector now represents more than 20% of all victims since we started observing the leak sites in the beginning of 2020. Approximately 28% of all our clients are from Manufacturing, contributing with an overall share of 31% of all p

Multiple threat actors, including a nation-state group, exploited a critical three-year-old security flaw in Progress Telerik to break into an unnamed federal entity in the U.S. The  disclosure  comes from a  joint advisory  issued by the Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), and Multi-State Information Sharing and Analysis Center (MS-ISAC). "Exploitation of this vulnerability allowed malicious actors to successfully execute remote code on a federal civilian executive branch (FCEB) agency's Microsoft Internet Information Services (IIS) web server," the agencies  said . The indicators of compromise (IoCs) associated with the digital break-in were identified from November 2022 through early January 2023. Tracked as  CVE-2019-18935  (CVSS score: 9.8), the issue relates to a .NET  deserialization vulnerability  affecting Progress Telerik UI for ASP.NET AJAX that, if left unpatched, could  lead to remote code exec

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on March 15  added  a security vulnerability impacting Adobe ColdFusion to its Known Exploited Vulnerabilities (KEV) catalog, based on evidence of active exploitation. The critical flaw in question is  CVE-2023-26360  (CVSS score: 8.6), which could be exploited by a threat actor to achieve arbitrary code execution. "Adobe ColdFusion contains an improper access control vulnerability that allows for remote code execution," CISA  said . The vulnerability impacts ColdFusion 2018 (Update 15 and earlier versions) and ColdFusion 2021 (Update 5 and earlier versions). It has been addressed in versions Update 16 and Update 6, respectively, released on March 14, 2023. It's worth noting that CVE-2023-26360 also affects ColdFusion 2016 and ColdFusion 11 installations, both of which are no longer supported by the software company as they have  reached  end-of-life (EoL). While the exact details surrounding the natu

A previously undocumented threat actor dubbed  YoroTrooper  has been targeting government, energy, and international organizations across Europe as part of a cyber espionage campaign that has been active since at least June 2022. "Information stolen from successful compromises include credentials from multiple applications, browser histories and cookies, system information and screenshots," Cisco Talos researchers Asheer Malhotra and Vitor Ventura  said  in a Tuesday analysis. Prominent countries targeted include Azerbaijan, Tajikistan, Kyrgyzstan, Turkmenistan, and other Commonwealth of Independent States (CIS) nations. The threat actor is believed to be Russian-speaking owing to the victimology patterns and the presence of Cyrillic snippets in some of the implants. That said, the YoroTrooper intrusion set has been found to exhibit tactical overlaps with the  PoetRAT team  that was  documented  in 2020 as leveraging coronavirus-themed baits to strike government and ene

Cybersecurity researchers have discovered the first-ever illicit cryptocurrency mining campaign used to mint Dero since the start of February 2023. "The novel Dero cryptojacking operation concentrates on locating Kubernetes clusters with anonymous access enabled on a Kubernetes API and listening on non-standard ports accessible from the internet," CrowdStrike  said  in a new report shared with The Hacker News. The development marks a notable shift from Monero, which is a prevalent cryptocurrency used in such campaigns. It's suspected it may have to do with the fact that  Dero  "offers larger rewards and provides the same or better anonymizing features." The attacks, attributed to an unknown financially motivated actor, commence with scanning for Kubernetes clusters with authentication set as  --anonymous-auth=true , which allows anonymous requests to the server, to drop initial payloads from three different U.S.-based IP addresses. This includes deploying

The stakes could not be higher for cyber defenders. With the vast amounts of sensitive information, intellectual property, and financial data at risk, the consequences of a data breach can be devastating. According to a report released by  Ponemon institute , the cost of data breaches has reached an all-time high, averaging $4.35 million in 2022. Vulnerabilities in web applications are often the primary gateway for attackers. According to  a World Economic Forum report , just one week after discovering a critical security flaw in a widely used software library (Log4j), more than 100 attempts at exploiting the vulnerability were detected every minute. This illustrates how quickly malicious actors can take advantage of vulnerabilities, highlighting the urgency of regularly assessing and monitoring your system for any vulnerabilities or weak points. The complexity of addressing security challenges in today's digital world is further compounded by the rising use of open-source compo

A cyberespionage actor known as Tick has been attributed with high confidence to a compromise of an East Asian data-loss prevention (DLP) company that caters to government and military entities. "The attackers compromised the DLP company's internal update servers to deliver malware inside the software developer's network, and trojanized installers of legitimate tools used by the company, which eventually resulted in the execution of malware on the computers of the company's customers," ESET researcher Facundo Muñoz  said . Tick , also known as Bronze Butler, REDBALDKNIGHT , Stalker Panda, and Stalker Taurus, is a suspected China-aligned collective that has primarily gone after government, manufacturing, and biotechnology firms in Japan. It's said to be active  since at least 2006 . Other lesser-known targets include Russian, Singaporean, and Chinese enterprises. Attack chains orchestrated by the group have typically leveraged spear-phishing emails and  str

Microsoft's Patch Tuesday update for March 2023 is rolling out with remediations for a set of  80 security flaws , two of which have come under active exploitation in the wild. Eight of the 80 bugs are rated Critical, 71 are rated Important, and one is rated Moderate in severity. The updates are in  addition to 29 flaws  the tech giant fixed in its Chromium-based Edge browser in recent weeks. The two vulnerabilities that have come under active attack include a Microsoft Outlook privilege escalation flaw ( CVE-2023-23397 , CVSS score: 9.8) and a Windows SmartScreen security feature bypass ( CVE-2023-24880 , CVSS score: 5.1). CVE-2023-23397 is "triggered when an attacker sends a message with an extended MAPI property with a UNC path to an SMB (TCP 445) share on a threat actor-controlled server," Microsoft  said  in a standalone advisory. A threat actor could leverage this flaw by sending a specially crafted email, activating it automatically when it is retrieved and pr

A new Golang-based malware dubbed  GoBruteforcer  has been found targeting web servers running phpMyAdmin, MySQL, FTP, and Postgres to corral the devices into a botnet. "GoBruteforcer chose a Classless Inter-Domain Routing ( CIDR ) block for scanning the network during the attack, and it targeted all IP addresses within that CIDR range," Palo Alto Networks Unit 42 researchers  said . "The threat actor chose CIDR block scanning as a way to get access to a wide range of target hosts on different IPs within a network instead of using a single IP address as a target." GoBruteforcer is mainly designed to single out Unix-like platforms running x86, x64 and ARM architectures, with  the malware attempting to obtain access via a brute-force attack using a list of credentials hard-coded into the binary. If the attack proves to be successful, an internet relay chat ( IRC ) bot is deployed on the victim server to establish communications with an actor-controlled server.

Today, the LockBit ransomware is the most active and successful cybercrime organization in the world. Attributed to a Russian Threat Actor, LockBit has stepped out from the shadows of the Conti ransomware group, who were disbanded in early 2022. LockBit ransomware was first discovered in September 2019 and was previously known as ABCD ransomware because of the ".abcd virus" extension first observed. LockBit operates as a Ransomware-as-a-service (RaaS) model. In short, this means that affiliates make a deposit to use the tool, then split the ransom payment with the LockBit group. It has been reported that some affiliates are receiving a share as high of 75%. LockBit's operators have posted advertisements for their affiliate program on Russian-language criminal forums stating they will not operate in Russia or any CIS countries, nor will they work with English-speaking developers unless a Russian-speaking "guarantor" vouches for them.  Initial attack vectors of
