Cybersecurity researchers today revealed the existence of a new and previously undetected critical vulnerability in SIM cards that could allow remote attackers to compromise targeted mobile phones and spy on victims just by sending an SMS. Dubbed " SimJacker ," the vulnerability resides in a particular piece of software, called the S@T Browser (a dynamic SIM toolkit), embedded on most SIM cards that is widely being used by mobile operators in at least 30 countries and can be exploited regardless of which handsets victims are using. What's worrisome? A specific private company that works with governments is actively exploiting the SimJacker vulnerability from at least the last two years to conduct targeted surveillance on mobile phone users across several countries. S@T Browser , short for SIMalliance Toolbox Browser, is an application that comes installed on a variety of SIM cards, including eSIM, as part of SIM Tool Kit (STK) and has been designed to let mobile

Unlike previous side-channel vulnerabilities disclosed in Intel CPUs, researchers have discovered a new flaw that can be exploited remotely over the network without requiring an attacker to have physical access or any malware installed on a targeted computer. Dubbed NetCAT , short for Network Cache ATtack, the new network-based side-channel vulnerability could allow a remote attacker to sniff out sensitive data, such as someone's SSH password, from Intel's CPU cache. Discovered by a team of security researchers from the Vrije University in Amsterdam, the vulnerability, tracked as CVE-2019-11184, resides in a performance optimization feature called Intel's DDIO—short for Data-Direct I/O—which by design grants network devices and other peripherals access to the CPU cache. The DDIO comes enabled by default on all Intel server-grade processors since 2012, including Intel Xeon E5, E7 and SP families. According to the researchers [ paper ], NetCAT attack works simila

The  ransomware industry surged in 2023  as it saw an alarming 55.5% increase in victims worldwide, reaching a staggering 5,070.  But 2024 is starting off showing a very different picture.  While the numbers skyrocketed in Q4 2023 with 1309 cases, in Q1 2024, the ransomware industry was down to 1,048 cases. This is a 22% decrease in ransomware attacks compared to Q4 2023. Figure 1: Victims per quarter There could be several reasons for this significant drop.  Reason 1: The Law Enforcement Intervention Firstly, law enforcement has upped the ante in 2024 with actions against both LockBit and ALPHV. The LockBit Arrests In February, an international operation named "Operation Cronos" culminated in the arrest of at least three associates of the infamous LockBit ransomware syndicate in Poland and Ukraine.  Law enforcement from multiple countries collaborated to take down LockBit's infrastructure. This included seizing their dark web domains and gaining access to their backend sys

CISOs and CIOs need to know better than anyone the security pulse of their organizations. On the other hand, they cannot be flooded with every changing detail. Finding the right balance that enables them to clearly grasp the big picture required in making sound decisions is a task many security executives find challenging. Threat actors do not acknowledge off-hours or weekends, introducing the need for constant vigilance. Moreover, CIOs and CISOs are heavily dependent on their team for knowledge and often lack the immediate interaction with the events in real-time. This situation is also far from favorable – after all, who if not the security executive should have the ability to be in-the-know and initiate action at the heart of things? Cynet rises to this challenge with the recently launched Cynet Dashboard application, which provides 24/7 insight into the overall security posture, real-time visibility into newly detected threats, and the ability to take rapid action if the nee

Mozilla has officially launched a new privacy-focused VPN service, called Firefox Private Network , as a browser extension that aims to encrypt your online activity and limit what websites and advertisers know about you. Firefox Private Network service is currently in beta and available only to desktop users in the United States as part of Mozilla's recently expunged "Firefox Test Pilot" program that lets users try out new experimental features before they were officially released. The Firefox Test Pilot program was first launched by the company three years ago but was shut down in January this year. The company now decided to bring the program back but with some changes. "The difference with the newly relaunched Test Pilot program is that these products and services may be outside the Firefox browser, and will be far more polished, and just one step shy of general public release," said Marissa Wood, vice president of product at Mozilla. Firefox

What could be worse than your router leaking its administrative login credentials in plaintext? Cybersecurity researchers from Trustwave's SpiderLabs have discovered multiple security vulnerabilities in some router models from two popular manufacturers—D-Link and Comba Telecom—that involve insecure storage of credentials, potentially affecting every user and system on that network. Researcher Simon Kenin told The Hacker News that he discovered a total of five vulnerabilities—two in a D-Link DSL modem typically installed to connect a home network to an ISP, and three in multiple Comba Telecom WiFi devices. These flaws could potentially allow attackers to change your device settings, extract sensitive information, perform MitM attacks, redirect you to phishing or malicious sites and launch many more types of attacks. "Since your router is the gateway in and out of your entire network it can potentially affect every user and system on that network. An attacker-controlled

Cybersecurity researchers have discovered a new computer virus associated with the Stealth Falcon state-sponsored cyber espionage group that abuses a built-in component of the Microsoft Windows operating system to stealthily exfiltrate stolen data to attacker-controlled server. Active since 2012, Stealth Falcon is a sophisticated hacking group known for targeting journalists, activists, and dissidents with spyware in the Middle East, primarily in the United Arab Emirates (UAE). Dubbed Win32/StealthFalcon , named after the hacking group, the malware communicates and sends collected data to its remote command-and-control (C&C) servers using Windows Background Intelligent Transfer Service (BITS). BITS is a communication protocol in Windows that takes unused network bandwidth to facilitate asynchronous, prioritized, and throttled transfer of files between machines in the foreground or background, without impacting the network experience. BITS is commonly used by software up

Twitter today finally decided to temporarily disable a feature, called ' Tweeting via SMS ,' after it was abused by a hacking group to compromise Twitter CEO Jack Dorsey last week and sent a series of racist and offensive tweets to Dorsey's followers. Dorsey's Twitter account was compromised last week when a hacker group calling itself "Chuckling Squad" replicated a mobile phone number associated with the CEO account and abused this particular feature to post racist, offensive messages and bomb threats from it via SMS. Replicating a mobile phone number associated with someone else is a technique known as " SIM swapping ," where attackers social engineer a victim's mobile phone provider and trick the telecom company to transfer target's phone number to their own SIM card. Once they social engineered an AT&T employee and gained access to Dorsey's phone number, the Chuckling Squad hackers used the 'Tweeting via SMS' feat

Cybersecurity researchers have discovered over 80 Magecart compromised e-commerce websites that were actively sending credit card information of online shoppers to the attackers-controlled servers. Operating their businesses in the United States, Canada, Europe, Latin America, and Asia, many of these compromised websites are reputable brands in the motorsports industry and high fashion, researchers at Aite Group and Arxan Technologies revealed today in a report shared with The Hacker News. In a world that's growing increasingly digital, Magecart attacks have emerged as a key cybersecurity threat to e-commerce websites. Magecart is an umbrella term given to different cybercriminal groups that are specialized in secretly implanting online credit card skimmers on compromised e-commerce websites with an intent to steal payment card details of their customers. These virtual credit card skimmers, also known as formjacking attack , are basically JavaScript code that hackers

Silence APT , a Russian-speaking cybercriminal group, known for targeting financial organizations primarily in former Soviet states and neighboring countries is now aggressively targeting banks in more than 30 countries across America, Europe, Africa, and Asia. Active since at least September 2016, Silence APT group's most recent successful campaign was against Bangladesh-based Dutch-Bangla Bank, which lost over $3 million during a string of ATM cash withdrawals over a span of several days. According to a new report Singapore-based cybersecurity firm Group-IB shared with The Hacker News, the hacking group has significantly expanded their geography in recent months, increased the frequency of their attack campaigns, as well as enhanced its arsenal. The report also describes the evolution of the Silence hacking group from "young and highly motivated hackers" to one of the most sophisticated advanced persistent threat (APT) group that is now posing threats to bank

If you are using LibreOffice, you need to update it once again. LibreOffice has released the latest version 6.2.6/6.3.0 of its open-source office software to address three new vulnerabilities that could allow attackers to bypass patches for two previously addressed vulnerabilities. LibreOffice is one of the most popular and open source alternatives to Microsoft Office suite and is available for Windows, Linux and macOS systems. One of the two vulnerabilities, tracked as CVE-2019-9848 , that LibreOffice attempted to patch just last month was a code execution flaw that affected LibreLogo, a programmable turtle vector graphics script that ships by default with LibreOffice. This flaw allows an attacker to craft a malicious document that can silently execute arbitrary python commands without displaying any warning to a targeted user. Apparently, the patch for this vulnerability was insufficient, as The Hacker News also reported late last month , which allowed two separate secu

The threat of ransomware is becoming more prevalent and severe as attackers' focus has now moved beyond computers to smartphones and other Internet-connected smart devices. In its latest research, security researchers at cybersecurity firm CheckPoint demonstrated how easy it is for hackers to remotely infect a digital DSLR camera with ransomware and hold private photos and videos hostage until victims pay a ransom. Yes, you heard me right. Security researcher Eyal Itkin discovered several security vulnerabilities in the firmware of Canon cameras that can be exploited over both USB and WiFi, allowing attackers to compromise and take over the camera and its features. According to a security advisory  released  by Canon, the reported security flaws affect Canon EOS-series digital SLR and mirrorless cameras, PowerShot SX740 HS, PowerShot SX70 HS, and PowerShot G5X Mark II. "Imagine how would you respond if attackers inject ransomware into both your computer and the c

Apple has just updated the rules of its bug bounty program by announcing a few major changes during a briefing at the annual Black Hat security conference yesterday. One of the most attractive updates is… Apple has enormously increased the maximum reward for its bug bounty program from $200,000 to $1 million—that's by far the biggest bug bounty offered by any major tech company for reporting vulnerabilities in its products. The $1 million payouts will be rewarded for a severe deadly exploit—a zero-click kernel code execution vulnerability that enables complete, persistent control of a device's kernel. Less severe exploits will qualify for smaller payouts. What's more? From now onwards, Apple's bug bounty program is not just applicable for finding security vulnerabilities in the iOS mobile operating system, but also covers all of its operating systems, including macOS , watchOS, tvOS, iPadOS, and iCloud. Since its inception around three years ago, Apple

Cisco Systems has agreed to pay $8.6 million to settle a lawsuit that accused the company of knowingly selling video surveillance system containing severe security vulnerabilities to the U.S. federal and state government agencies. It's believed to be the first payout on a ' False Claims Act ' case over failure to meet cybersecurity standards. The lawsuit began eight years ago, in the year 2011, when Cisco subcontractor turned whistleblower, James Glenn, accused Cisco of continue selling a video surveillance technology to federal agencies even after knowing that the software was vulnerable to multiple security flaws. According to the court documents seen by The Hacker News, Glenn and one of his colleagues discovered multiple vulnerabilities in Cisco Video Surveillance Manager (VSM) suite in September 2008 and tried to report them to the company in October 2008. Cisco Video Surveillance Manager (VSM) suite allows customers to manage multiple video cameras at different

Another week, another massive data breach. Capital One, the fifth-largest U.S. credit-card issuer and banking institution, has recently suffered a data breach exposing the personal information of more than 100 million credit card applicants in the United States and 6 million in Canada. The data breach that occurred on March 22nd and 23rd this year allowed attackers to steal information of customers who had applied for a credit card between 2005 and 2019, Capital One said in a statement. However, the security incident only came to light after July 19 when a hacker posted information about the theft on her GitHub account. The FBI Arrested the Alleged Hacker The FBI arrested Paige Thompson a.k.a erratic, 33, a former Amazon Web Services software engineer who worked for a Capital One contractor from 2015 to 2016, in relation to the breach, yesterday morning and seized electronic storage devices containing a copy of the stolen data. Thompson appeared in U.S. District Court o

A former Siemens contractor has pledged guilty in federal court Friday to secretly planting code in automated spreadsheets he had created for the company over a decade ago that deliberately crashes the program every few years. David Tinley, a 62-year-old resident of Harrison City, Pennsylvania, was hired by Siemens as a contract employee for Monroeville, Pennsylvania location, in 2002 to create custom automated spreadsheets for various Siemens projects related to the power generation industry. However, according to the United States Justice Department ( DoJ ), Tinley intentionally and without the company's knowledge or authorization inserted "logic bombs" into computer programs that caused glitches in the spreadsheet after the expiration of a certain date. Logic Bomb is a piece of computer code intentionally inserted into software or system to carry out specific operations like crash or malfunction after certain conditions are met, or an amount of time has expire

If you are in Kazakhstan and unable to access the Internet service without installing a certificate, you're not alone. The Kazakhstan government has once again issued an advisory to all major local Internet Service Providers (ISPs) asking them to make it mandatory for all their customers to install government-issued root certificates on their devices in order to regain access to the Internet services. The root certificate in question, labeled as " trusted certificate " or " national security certificate ," if installed, allows ISPs to intercept and monitor users' encrypted HTTPS and TLS connections, helping the government spy on its citizens and censor content. In other words, the government is essentially launching a "man in the middle" attack on every resident of the country. But how installing a "root certificate" allow ISPs to decrypt HTTPS connection? For those unaware, your device and web browsers automatically trust digi

Earlier this month, The Hacker News covered a story on research revealing how over 1300 Android apps are collecting sensitive data even when users have explicitly denied the required permissions. The research was primarily focused on how app developers abuse multiple ways around to collect location data, phone identifiers, and MAC addresses of their users by exploiting both covert and side channels. Now, a separate team of cybersecurity researchers has successfully demonstrated a new side-channel attack that could allow malicious apps to eavesdrop on the voice coming out of your smartphone's loudspeakers without requiring any device permission. Abusing Android Accelerometer to Capture Loudspeaker Data Dubbed Spearphone , the newly demonstrated attack takes advantage of a hardware-based motion sensor, called an accelerometer, which comes built into most Android devices and can be unrestrictedly accessed by any app installed on a device even with zero permissions.
