Experts Believe Chinese Hackers Are Behind Several Attacks Targeting Israel

Experts Believe Chinese Hackers Are Behind Several Attacks Targeting Israel

Aug 10, 2021
A Chinese cyber espionage group has been linked to a string of intrusion activities targeting Israeli government institutions, IT providers, and telecommunications companies at least since 2019, with the hackers masquerading themselves as Iranian actors to mislead forensic analysis. FireEye's Mandiant threat intelligence arm attributed the campaign to an operator it tracks as "UNC215", a Chinese espionage operation that's believed to have singled out organizations around the world dating back as far as 2014, linking the group with "low confidence" to an advanced persistent threat (APT) widely known as  APT27 , Emissary Panda, or Iron Tiger. "UNC215 has compromised organizations in the government, technology, telecommunications, defense, finance, entertainment, and health care sectors," FireEye's Israel and U.S. threat intel teams  said  in a report published today. "The group targets data and organizations which are of great interest ...

A Critical Random Number Generator Flaw Affects Billions of IoT Devices

A Critical Random Number Generator Flaw Affects Billions of IoT Devices

Aug 09, 2021
A critical vulnerability has been disclosed in hardware random number generators used in billions of Internet of Things (IoT) devices whereby it fails to properly generate random numbers, thus undermining their security and putting them at risk of attacks. "It turns out that these 'randomly' chosen numbers aren't always as random as you'd like when it comes to IoT devices," Bishop Fox researchers Dan Petro and Allan Cecil  said  in an analysis published last week. "In fact, in many cases, devices are choosing encryption keys of 0 or worse. This can lead to a catastrophic collapse of security for any upstream use." Random number generation ( RNG ) is a  crucial process  that undergirds several cryptographic applications, including key generation, nonces, and salting. On traditional operating systems, it's derived from a cryptographically secure pseudorandom number generator (CSPRNG) that uses entropy obtained from a high-quality seed source. ...
Users Can Be Just As Dangerous As Hackers

Users Can Be Just As Dangerous As Hackers

Aug 09, 2021
Among the problems stemming from our systemic failure with cybersecurity, which ranges from decades-old software-development practices to Chinese and Russian cyber-attacks, one problem gets far less attention than it should—the insider threat. But the reality is that most organizations should be at least as worried about user management as they are about Bond villain-type hackers launching compromises from abroad. Most organizations have deployed single sign-on and modern identity-management solutions. These generally allow easy on-boarding, user management, and off-boarding. However, on mobile devices, these solutions have been less effective. Examples include mobile applications such as WhatsApp, Signal, Telegram, or even SMS-which are common in the workforce. All of these tools allow for low-friction, agile communication in an increasingly mobile business environment. Today, many of these tools offer end-to-end encryption (e2ee), which is a boon when viewed through the lens of ...
Beware! New Android Malware Hacks Thousands of Facebook Accounts

Beware! New Android Malware Hacks Thousands of Facebook Accounts

Aug 09, 2021
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...
Pulse Secure VPNs Get New Urgent Update for Poorly Patched Critical Flaw

Pulse Secure VPNs Get New Urgent Update for Poorly Patched Critical Flaw

Aug 09, 2021
Pulse Secure has shipped a fix for a critical post-authentication remote code execution (RCE) vulnerability in its Connect Secure virtual private network (VPN) appliances to address an incomplete patch for an actively exploited flaw it previously resolved in October 2020. "The Pulse Connect Secure appliance suffers from an uncontrolled archive extraction vulnerability which allows an attacker to overwrite arbitrary files, resulting in Remote Code Execution as root," NCC Group's Richard Warren  disclosed  on Friday. "This vulnerability is a bypass of the patch for  CVE-2020-8260 ." "An attacker with such access will be able to circumvent any restrictions enforced via the web application, as well as remount the filesystem, allowing them to create a persistent backdoor, extract and decrypt credentials, compromise VPN clients, or pivot into the internal network," Warren added. The disclosure comes days after Ivanti, the company behind Pulse Secure,  p...
Apple to Scan Every Device for Child Abuse Content — But Experts Fear for Privacy

Apple to Scan Every Device for Child Abuse Content — But Experts Fear for Privacy

Aug 06, 2021
Apple on Thursday said it's introducing new child safety features in iOS, iPadOS, watchOS, and macOS as part of its efforts to limit the spread of Child Sexual Abuse Material (CSAM) in the U.S. To that effect, the iPhone maker said it intends to begin client-side scanning of images shared via every Apple device for known child abuse content as they are being uploaded into iCloud Photos, in addition to leveraging on-device machine learning to vet all iMessage images sent or received by minor accounts (aged under 13) to warn parents of sexually explicit photos shared over the messaging platform. Furthermore, Apple also plans to update Siri and Search to stage an intervention when users try to perform searches for CSAM-related topics, alerting that the "interest in this topic is harmful and problematic." "Messages uses on-device machine learning to analyze image attachments and determine if a photo is sexually explicit," Apple  noted . "The feature is desi...
New Amazon Kindle Bug Could've Let Attackers Hijack Your eBook Reader

New Amazon Kindle Bug Could've Let Attackers Hijack Your eBook Reader

Aug 06, 2021
Amazon earlier this April addressed a critical vulnerability in its Kindle e-book reader platform that could have been potentially exploited to take full control over a user's device, resulting in the theft of sensitive information by just deploying a malicious e-book. "By sending Kindle users a single malicious e-book, a threat actor could have stolen any information stored on the device, from Amazon account credentials to billing information," Yaniv Balmas, head of cyber research at Check Point, said in an emailed statement. "The security vulnerabilities allow an attacker to target a very specific audience." In other words, if a threat actor wanted to single out a specific group of people or demographic, it's possible for the adversary to choose a popular e-book in a language or dialect that's widely spoken among the group to tailor and orchestrate a highly targeted cyber attack. Upon responsibly disclosing the issue to Amazon in February 2021, t...
India's Koo, a Twitter-like Service, Found Vulnerable to Critical Worm Attacks

India's Koo, a Twitter-like Service, Found Vulnerable to Critical Worm Attacks

Aug 06, 2021
Koo, India's homegrown Twitter clone, recently patched a serious security vulnerability that could have been exploited to execute arbitrary JavaScript code against hundreds of thousands of its users, spreading the attack across the platform. The vulnerability involves a  stored cross-site scripting flaw  (also known as persistent XSS) in Koo's web application that allows malicious scripts to be embedded directly into the affected web application. To carry out the attack, all a malicious actor had to do was log into the service via the web application and post an XSS-encoded payload to its timeline, which automatically gets executed on behalf of all users who saw the post. The issue was discovered by security researcher  Rahul Kankrale  in July, following which a fix was rolled out by Koo on July 3. Using cross-site scripting, an attacker can perform actions on behalf of users with the same privileges as the user and steal web browser's secrets, such as authenti...

Salesforce Release Updates — A Cautionary Tale for Security Teams

Salesforce Release Updates — A Cautionary Tale for Security Teams

Aug 05, 2021
On the surface, Salesforce seems like a classic Software-as-a-Service (SaaS) platform. Someone might even argue that Salesforce invented the SaaS market. However, the more people work with the full offering of Salesforce, the more they realize that it goes beyond a traditional SaaS platform's capabilities. For example, few people talk about managing the security aspects of  Salesforce Release Updates.  By understanding what Release Updates are, why they pose a security risk, and how security teams can mitigate risk, Salesforce customers can better protect sensitive information. How to ensure the right configurations for your Salesforce security What are Salesforce Release Updates? Since Salesforce does not automatically update its platform, it does not follow the traditional SaaS model. For example, most SaaS platforms have two types of releases, security, and product improvements. Urgent security updates are released as soon as a security vulnerability is known, and prod...

Cisco Issues Critical Security Patches to Fix Small Business VPN Router Bugs

Aug 05, 2021
Networking equipment major Cisco has rolled out patches to address critical vulnerabilities impacting its Small Business VPN routers that could be abused by a remote attacker to execute arbitrary code and even cause a denial-of-service (DoS) condition. The issues, tracked as CVE-2021-1609 (CVSS score: 9.8) and CVE-2021-1610 (CVSS score: 7.2), reside in the web-based management interface of the Small Business RV340, RV340W, RV345, and RV345P Dual WAN Gigabit VPN Routers running a firmware release prior to version 1.0.03.22. Both the issues stem from a lack of proper validation of HTTP requests, thus permitting a bad actor to send a specially-crafted HTTP request to a vulnerable device. Successful exploitation of CVE-2021-1609 could allow an unauthenticated, remote attacker to execute arbitrary code on the device or cause the device to reload, resulting in a DoS condition. CVE-2021-1610, concerns a command injection vulnerability that, if exploited, could permit an authenticated adve...

Several Malware Families Targeting IIS Web Servers With Malicious Modules

Aug 04, 2021
A systematic analysis of attacks against Microsoft's Internet Information Services (IIS) servers has revealed as many as 14 malware families, 10 of them newly documented, indicating that the Windows-based web server software continues to be a hotbed for  natively developed malware  for close to eight years. The findings were presented today by ESET malware researcher Zuzana Hromcova at the  Black Hat USA security conference . "The various kinds of native IIS malware identified are server-side malware and the two things it can do best is, first, see and intercept all communications to the server, and second, affect how the requests are processed," Hromcova told in an interview with The Hacker News. "Their motivations range from cybercrime to espionage, and a technique called SEO fraud." Government institutions in three Southeast Asian countries, a major telecommunications company in Cambodia, and a research institution in Vietnam, as well as dozens of private...
