Meta Platforms on Thursday revealed it took steps to deplatform seven cyber mercenaries that it said carried out "indiscriminate" targeting of journalists, dissidents, critics of authoritarian regimes, families of opposition, and human rights activists located in over 100 countries, amid mounting scrutiny of surveillance technologies. To that end, the company  said  it alerted 50,000 users of Facebook and Instagram that their accounts were spied on by the companies, who offer a variety of services that run the spyware gamut from hacking tools for infiltrating mobile phones to creating fake social media accounts to monitor targets. It also removed 1,500 Facebook and Instagram accounts linked to these firms. "The global surveillance-for-hire industry targets people across the internet to collect intelligence, manipulate them into revealing information and compromise their devices and accounts," Meta's David Agranovich and Mike Dvilyanski said. "These compa...

Industrial and government organizations, including enterprises in the military-industrial complex and research laboratories, are the targets of a new malware botnet dubbed  PseudoManyscrypt  that has infected roughly 35,000 Windows computers this year alone. The name comes from its similarities to the  Manuscrypt   malware , which is part of the  Lazarus  APT group's attack toolset, Kaspersky researchers said, characterizing the operation as a "mass-scale spyware attack campaign." The Russian cybersecurity company said it first detected the series of intrusions in June 2021. At least 7.2% of all computers attacked by the malware are part of industrial control systems (ICS) used by organizations in engineering, building automation, energy, manufacturing, construction, utilities, and water management sectors that are located mainly in India, Vietnam, and Russia. Approximately a third (29.4%) of non-ICS computers are situated in Russia (10.1%), India (10%),...

It's no secret that the internet isn't a very safe place. And it's not hard to understand why. It's a medium that connects billions of people around the world that affords bad actors enough anonymity to wreak havoc without getting caught. It's almost as if the internet's tailor-made to enable scams and fraud. And that's just what it does. Right now, the world's on track to  lose $10.5 trillion every year  to cybercrime. That number is so large that it's hard for the average person to grasp. And when most people hear it, they imagine that money's coming mostly from large-scale data breaches and ransomware attacks on large companies. Although businesses are among the hardest hit each year, they're by no means the only target. Every day, internet users are targeted too. They face barrages of phishing emails, compromised websites, and booby-trapped downloads. But among all of the attacks aimed at rank-and-file users, there's one that stand...

Cryptocurrency users in Ethiopia, Nigeria, India, Guatemala, and the Philippines are being targeted by a new variant of the Phorpiex botnet called  Twizt  that has resulted in the theft of virtual coins amounting to $500,000 over the last one year. Israeli security firm Check Point Research, which detailed the attacks, said the latest evolutionary version "enables the botnet to operate successfully without active [command-and-control] servers," adding it supports no less than 35 wallets associated with different blockchains, including Bitcoin, Ethereum, Dash, Dogecoin, Litecoin, Monero, Ripple, and Zilliqa, to facilitate crypto theft. Phorpiex , otherwise known as Trik, is known for its sextortion spam and ransomware campaigns as well as cryptojacking, a scheme that leverages the targets' devices such as computers, smartphones, and servers to secretly mine cryptocurrency without their consent or knowledge. It's also infamous for its use of a technique called  cry...

Cybersecurity researchers have demonstrated a new attack technique that makes it possible to leverage a device's Bluetooth component to directly extract network passwords and manipulate traffic on a Wi-Fi chip, putting billions of electronic devices at risk of stealthy attacks. The novel attacks work against the so-called "combo chips," which are specialized chips that are equipped to handle different types of radio wave-based wireless communications, such as Wi-Fi, Bluetooth, and LTE. "We provide empirical evidence that coexistence, i.e., the coordination of cross-technology wireless transmissions, is an unexplored attack surface," a group of researchers from the Technical University of Darmstadt's Secure Mobile Networking Lab and the University of Brescia said in a  new paper . "Instead of escalating directly into the mobile [operating system], wireless chips can escalate their privileges into other wireless chips by exploiting the same mechanisms...

Cyber threats used to be less threatening. While nobody wants their customers' credit card numbers stolen in a data breach, or to see a deranged manifesto plastered over their company website, such incidents can almost seem quaint compared to ransomware attacks that bring all of your critical information systems to a dead halt. The frequency of these attacks  increased more than 150% in the U.S. last year, and in 2021 their global cost is expected to reach $20 billion. Effective, comprehensive security training is essential to mitigating these threats, many of which originate with low-profile phishing or malware attacks to get a foot in the door—attacks that can target anyone who works in your organization. A company's employees are the front line of defense against cyberattacks, and canned training videos and short quizzes are rarely sufficient to prepare them for this responsibility. The trouble with good training is that it takes not just expertise but time and other reso...

A new JavaScript-based remote access Trojan (RAT) propagated via a social engineering campaign has been observed employing sneaky "fileless" techniques as part of its detection-evasion methods to elude discovery and analysis. Dubbed DarkWatchman by researchers from Prevailion's Adversarial Counterintelligence Team (PACT), the malware uses a resilient domain generation algorithm ( DGA ) to identify its command-and-control (C2) infrastructure and utilizes the Windows Registry for all of its storage operations, thereby enabling it to bypass antimalware engines. The RAT "utilizes novel methods for fileless persistence, on-system activity, and dynamic run-time capabilities like self-updating and recompilation," researchers Matt Stafford and Sherman Smith  said , adding it "represents an evolution in fileless malware techniques, as it uses the registry for nearly all temporary and permanent storage and therefore never writes anything to disk, allowing it to o...

Web infrastructure company Cloudflare on Wednesday revealed that threat actors are actively attempting to exploit a  second bug  disclosed in the widely used Log4j logging utility, making it imperative that customers move quickly to install the latest version as a barrage of attacks continues to pummel unpatched systems with a variety of malware. The new vulnerability, assigned the identifier  CVE-2021-45046 , makes it possible for adversaries to carry out denial-of-service (DoS) attacks and follows disclosure from the Apache Software Foundation (ASF) that the original fix for the remote code execution bug — CVE-2021-44228 aka Log4Shell — was "incomplete in certain non-default configurations." The issue has since been addressed in Log4j version 2.16.0. "This vulnerability is actively being exploited and anyone using Log4j should update to version 2.16.0 as soon as possible, even if you have previously updated to 2.15.0," Cloudflare's Andre Bluehs and Gabriel ...

Meta Platforms, the company formerly known as Facebook, has announced that it's expanding its  bug bounty program  to start rewarding valid reports of scraping vulnerabilities across its platforms as well as include reports of scraping data sets that are available online. "We know that automated activity designed to scrape people's public and private data targets every website or service," said Dan Gurfinkel, security engineering manager at Meta. "We also know that it is a highly adversarial space where scrapers — be it malicious apps, websites or scripts — constantly adapt their tactics to evade detection in response to the defenses we build and improve." To that end, the social media giant aims to  monetarily compensate  for valid reports of scraping bugs in its service and identify unprotected or openly public databases containing no less than 100,000 unique Facebook user records with personally identifiable information (PII) such as email, phone numb...

Today's cyber attackers are constantly looking for ways to exploit vulnerabilities and infiltrate organizations. To keep up with this evolving threat landscape, security teams must be on the lookout for potential risks around the clock. Since most organizations simply cannot afford to have 24x7 security teams, managed detection and response (MDR) services have become a critical aspect of any modern security stack.  Most organizations must find outsourced MDR providers on top of their existing solutions, but that's not always a feasible solution. XDR provider Cynet offers its MDR service ( learn more here ), which the company calls CyOps, as part of its offering. The service is much more than simply a help desk, though. CyOps offers a thorough MDR service that offers both monitoring and threat hunting, as well as incident response in cases where an attack is successful.  How CyOps operates The key selling point for CyOps MDR is that it enhances organizations' security a...

Malicious actors are deploying a previously undiscovered binary, an Internet Information Services ( IIS ) webserver module dubbed " Owowa ," on Microsoft Exchange Outlook Web Access servers with the goal of stealing credentials and enabling remote command execution. "Owowa is a C#-developed .NET v4.0 assembly that is intended to be loaded as a module within an IIS web server that also exposes Exchange's Outlook Web Access (OWA)," Kaspersky researchers Paul Rascagneres and Pierre Delcher  said . "When loaded this way, Owowa will steal credentials that are entered by any user in the OWA login page, and will allow a remote operator to run commands on the underlying server." The idea that a rogue IIS module can be fashioned as a backdoor is not new. In August 2021, an exhaustive study of the IIS threat landscape by Slovak cybersecurity company ESET revealed  as many as 14 malware families that were developed as native IIS modules in an attempt to interc...

Microsoft has rolled out  Patch Tuesday updates  to address multiple security vulnerabilities in Windows and other software, including one actively exploited flaw that's being abused to deliver Emotet, TrickBot, or Bazaloader malware payloads. The latest monthly release for December fixes a total of 67 flaws, bringing the total number of bugs patched by the company this year to 887, according to the  Zero Day Initiative . Seven of the 67 flaws are rated Critical and 60 are rated as Important in severity, with five of the issues publicly known at the time of release. It's worth noting that this is in addition to the  21 flaws  resolved in the Chromium-based Microsoft Edge browser. The most critical of the lot is  CVE-2021-43890  (CVSS score: 7.1), a Windows AppX installer spoofing vulnerability that Microsoft said could be exploited to achieve arbitrary code execution. The lower severity rating is indicative of the fact that code execution hinges on ...

UPDATE — The severity score of CVE-2021-45046, originally classified as a DoS bug, has since been revised from 3.7 to 9.0, to reflect the fact that an attacker could abuse the vulnerability to send a specially crafted string that leads to "information leak and remote code execution in some environments and local code execution in all environments." The Apache Software Foundation (ASF) has pushed out a new fix for the Log4j logging utility after the previous patch for the recently disclosed  Log4Shell  exploit was deemed as "incomplete in certain non-default configurations." The second vulnerability — tracked as  CVE-2021-45046  — is rated 3.7 out of a maximum of 10 on the CVSS rating system and affects all versions of Log4j from 2.0-beta9 through 2.12.1 and 2.13.0 through 2.15.0, which the project maintainers shipped last week to address a critical remote code execution vulnerability (CVE-2021-44228) that could be abused to infiltrate and take over systems. ...

Romanian cybersecurity technology company Bitdefender on Monday revealed that attempts are being made to target Windows machines with a novel ransomware family called  Khonsari  as well as a remote access Trojan named  Orcus  by exploiting the recently disclosed critical Log4j vulnerability . The attack leverages the remote code execution (RCE) flaw to download an additional payload, a .NET binary, from a remote server that encrypts all the files with the extension ".khonsari" and displays a ransom note that urges the victims to make a Bitcoin payment in exchange for recovering access to the files. Tracked as CVE-2021-44228 , the RCE vulnerability is also known by the monikers "Log4Shell" or "Logjam" and impacts versions 2.0-beta9 to 2.14.1 of the software library. In simple terms, the bug could force an affected system to download malicious software, giving the attackers a digital beachhead on servers located within corporate networks. Log4j is an op...
