A security vulnerability in Cisco Adaptive Security Appliance (ASA) that was addressed by the company last October, and again earlier this April, has been subjected to active in-the-wild attacks following the release of proof-of-concept (PoC) exploit code. The PoC was  published  by researchers from cybersecurity firm Positive Technologies on June 24, following which reports emerged that attackers are chasing after an exploit for the bug. "Tenable has also received a report that attackers are exploiting CVE-2020-3580 in the wild," the cyber exposure company  said . Tracked as  CVE-2020-3580  (CVSS score: 6.1), the issue concerns multiple vulnerabilities in the web services interface of Cisco ASA software and Cisco Firepower Threat Defense (FTD) software that could allow an unauthenticated, remote attacker to conduct cross-site scripting (XSS) attacks on an affected device. As of July 2020, there were a little over  85,000 ASA/FTD devices , 398 of which are spread acros

Taiwanese networking equipment company Zyxel is warning customers of an ongoing attack targeting a "small subset" of its security products such as firewall and VPN servers. Attributing the attacks to a "sophisticated threat actor," the firm noted that the attacks single out appliances that have remote management or SSL VPN enabled, namely in the USG/ZyWALL, USG FLEX, ATP, and VPN series running on-premise ZLD firmware, implying that the targeted devices are publicly accessible over the internet. "The threat actor attempts to access a device through WAN; if successful, they then bypass authentication and establish SSL VPN tunnels with unknown user accounts, such as 'zyxel_slIvpn', 'zyxel_ts', or 'zyxel_vpn_test', to manipulate the device's configuration," Zyxel said in an  email message , which was shared on Twitter. As of writing, it's not immediately known if the attacks are exploiting previously known vulnerabilities

Identities now transcend human boundaries. Within each line of code and every API call lies a non-human identity. These entities act as programmatic access keys, enabling authentication and facilitating interactions among systems and services, which are essential for every API call, database query, or storage account access. As we depend on multi-factor authentication and passwords to safeguard human identities, a pressing question arises: How do we guarantee the security and integrity of these non-human counterparts? How do we authenticate, authorize, and regulate access for entities devoid of life but crucial for the functioning of critical systems? Let's break it down. The challenge Imagine a cloud-native application as a bustling metropolis of tiny neighborhoods known as microservices, all neatly packed into containers. These microservices function akin to diligent worker bees, each diligently performing its designated task, be it processing data, verifying credentials, or

U.S. graphics chip specialist NVIDIA has released  software updates  to address a total of 26 vulnerabilities impacting its Jetson system-on-module (SOM) series that could be abused by adversaries to escalate privileges and even lead to denial-of-service and information disclosure. Tracked from CVE‑2021‑34372 through CVE‑2021‑34397, the flaws affect products Jetson TX1, TX2 series, TX2 NX, AGX Xavier series, Xavier NX, and Nano and Nano 2GB running all Jetson Linux versions prior to 32.5.1. The company credited Frédéric Perriot of Apple Media Products for reporting all the issues. The  NVIDIA Jetson  line consists of embedded Linux AI and computer vision compute modules and developer kits that primarily caters to AI-based computer vision applications and autonomous systems such as mobile robots and drones. Chief among the vulnerabilities is CVE‑2021‑34372 (CVSS score: 8.2), a buffer overflow flaw in its  Trusty  trusted execution environment (TEE) that could result in informatio

South Korea's state-run Korea Atomic Energy Research Institute (KAERI) on Friday disclosed that its internal network was infiltrated by suspected attackers operating out of its northern counterpart. The intrusion is said to have taken place on May 14 through a vulnerability in an unnamed virtual private network (VPN) vendor and involved a  total of 13 IP addresses , one of which — "27.102.114[.]89" — has been previously linked to a state-sponsored threat actor dubbed  Kimsuky . KAERI, established in 1959 and situated in the city of Daejeon, is a government-funded research institute that designs and develops nuclear technologies related to reactors, fuel rods, radiation fusion, and nuclear safety. Following the intrusion, the think tank said it took steps to block the attacker's IP addresses in question and applied necessary security patches to the vulnerable VPN solution. "Currently, the Atomic Energy Research Institute is investigating the subject of the ha

As software supply chain attacks emerge as a point of concern in the wake of SolarWinds and Codecov  security incidents, Google is proposing a solution to ensure the integrity of software packages and prevent unauthorized modifications.  Called " Supply chain Levels for Software Artifacts " (SLSA, and pronounced "salsa"), the end-to-end framework aims to secure the software development and deployment pipeline — i.e., the source ➞ build ➞ publish workflow — and  mitigate threats  that arise out of tampering with the source code, the build platform, and the artifact repository at every link in the chain. Google said SLSA is inspired by the company's own internal enforcement mechanism called Binary Authorization for Borg , a set of auditing tools that verifies code provenance and implements code identity to ascertain that the deployed production software is properly reviewed and authorized. "In its current state, SLSA is a set of incrementally adoptable

It's natural to get complacent with the status quo when things seem to be working. The familiar is comfortable, and even if something better comes along, it brings with it many unknowns. In cybersecurity, this tendency is countered by the fast pace of innovation and how quickly technology becomes obsolete, often overnight. This combination usually results in one of two things – organizations make less than ideal choices about the software and tools they're adding, or security leaders simply cannot stay abreast of new developments and opt to stay put with their existing stack. The problem is that once you let one update pass you by, you're suddenly miles behind. A new eBook from XDR provider Cynet ( download here ) offers insights into factors that are clear signs organizations need to upgrade their detection and response tools to stay with the times. The eBook highlights several factors and questions that companies can ask themselves to determine whether they are okay

Cybersecurity researchers have disclosed a new executable image tampering attack dubbed "Process Ghosting" that could be potentially abused by an attacker to circumvent protections and stealthily run malicious code on a Windows system. "With this technique, an attacker can write a piece of malware to disk in such a way that it's difficult to scan or delete it — and where it then executes the deleted malware as though it were a regular file on disk," Elastic Security researcher Gabriel Landau  said . "This technique does not involve code injection, Process Hollowing, or Transactional NTFS (TxF)." Process Ghosting expands on previously documented  endpoint bypass  methods such as  Process Doppelgänging  and  Process Herpaderping , thereby enabling the veiled execution of malicious code that may evade anti-malware defenses and detection. Process Doppelgänging, analogous to  Process Hollowing , involves injecting arbitrary code in the address space of

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday issued an advisory regarding a critical software supply-chain flaw impacting ThroughTek's software development kit (SDK) that could be abused by an adversary to gain improper access to audio and video streams. "Successful exploitation of this vulnerability could permit unauthorized access to sensitive information, such as camera audio/video feeds," CISA  said  in the alert. ThroughTek's point-to-point ( P2P ) SDK is widely used by IoT devices with video surveillance or audio/video transmission capability such as IP cameras, baby and pet monitoring cameras, smart home appliances, and sensors to provide remote access to the media content over the internet. Tracked as CVE-2021-32934 (CVSS score: 9.1), the shortcoming affects ThroughTek P2P products, versions 3.1.5 and before as well as SDK versions with nossl tag, and stems from a lack of sufficient protection when transferring data between

Cybersecurity researchers on Tuesday disclosed "distinctive" tactics, techniques, and procedures (TTPs) adopted by operators of Hades ransomware that set it apart from the rest of the pack, attributing it to a financially motivated threat group called  GOLD WINTER . "In many ways, the GOLD WINTER threat group is a typical post-intrusion ransomware threat group that pursues high-value targets to maximize how much money it can extort from its victims," researchers from SecureWorks Counter Threat Unit (CTU) said in an analysis shared with The Hacker News. "However, GOLD WINTER's operations have quirks that distinguish it from other groups." The findings come from a study of incident response efforts the Atlanta-based cybersecurity firm engaged in the first quarter of 2021. Since first emerging in the threat landscape in December 2020, Hades has been classified as INDRIK SPIDER's successor to  WastedLocker  ransomware with "additional code o

Multiple critical security flaws have been disclosed in Samsung's pre-installed Android apps, which, if successfully exploited, could have allowed adversaries access to personal data without users' consent and take control of the devices.  "The impact of these bugs could have allowed an attacker to access and edit the victim's contacts, calls, SMS/MMS, install arbitrary apps with device administrator rights, or read and write arbitrary files on behalf of a system user which could change the device's settings," Sergey Toshin, founder of mobile security startup Oversecured,  said  in an analysis published Thursday. Toshin reported the flaws to Samsung in February 2021, following which  patches were issued  by the manufacturer as part of its monthly security updates for April and May. The list of the seven vulnerabilities is as follows - CVE-2021-25356  - Third-party authentication bypass in Managed Provisioning CVE-2021-25388  - Arbitrary app installation

A seven-year-old privilege escalation vulnerability discovered in the polkit system service could be exploited by a malicious unprivileged local attacker to bypass authorization and escalate permissions to the root user. Tracked as  CVE-2021-3560  (CVSS score: 7.8), the flaw affects polkit versions between 0.113 and 0.118 and was discovered by GitHub security researcher Kevin Backhouse, who said the issue was  introduced in a code commit  made on Nov. 9, 2013. Red Hat's Cedric Buissart  noted  that Debian-based distributions, based on polkit 0.105, are also vulnerable. Polkit  (née PolicyKit) is a toolkit for defining and handling authorizations in Linux distributions, and is used for allowing unprivileged processes to communicate with privileged processes. "When a requesting process disconnects from dbus-daemon just before the call to polkit_system_bus_name_get_creds_sync starts, the process cannot get a unique uid and pid of the process and it cannot verify the privileg

An emerging ransomware strain in the threat landscape claims to have breached 30 organizations in just four months since it went operational by riding on the coattails of a notorious ransomware syndicate. First observed in February 2021, " Prometheus " is an offshoot of another well-known ransomware variant called  Thanos , which was previously deployed against state-run organizations in the Middle East and North Africa last year. The affected entities are believed to be government, financial services, manufacturing, logistics, consulting, agriculture, healthcare services, insurance agencies, energy and law firms in the U.S., U.K., and a dozen more countries in Asia, Europe, the Middle East, and South America, according to new research published by Palo Alto Networks' Unit 42 threat intelligence team. Like other ransomware gangs, Prometheus takes advantage of double-extortion tactics and hosts a dark web leak site, where it names and shames new victims and makes stol

Google on Thursday said it's rolling out new security features to Chrome browser aimed at detecting suspicious downloads and extensions via its Enhanced Safe Browsing feature, which it launched a year ago. To this end, the search giant said it will now offer additional protections when users attempt to install a new extension from the Chrome Web Store, notifying if it can be considered "trusted." Currently, 75% of all add-ons on the platform are compliant, the company pointed out, adding "any extensions built by a developer who follows the Chrome Web Store Developer Program Policies , will be considered trusted by Enhanced Safe Browsing." Enhanced Safe Browsing involves sharing real-time data with Google Safe Browsing to proactively safeguard users against dangerous sites. The company also noted that its integration with Safe Browsing's blocklist API helped improve privacy and security, with the number of malicious extensions disabled by the browser j

Major software vulnerabilities are a fact of life, as illustrated by the fact that Microsoft has patched between 55 and 110 vulnerabilities each month this year – with 7% to 17% of those vulnerabilities being critical. May had the fewest vulnerabilities, with a total of 55 and only four considered critical. The problem is that the critical vulnerabilities are things we have seen for many years, like remote code execution and privilege escalation. Microsoft isn't the only big name regularly patching major vulnerabilities: We see monthly security updates coming from Apple, Adobe, Google, Cisco, and others. Everything old is new again With major vulnerabilities in so many applications, is there any hope for a secure future? The answer is, of course, yes, but that does not mean there won't be challenges getting there. The vulnerabilities being seen may not be new to those of us who have been defending against attackers for years or even decades, but the adversaries continual

An ongoing cyber-espionage operation with suspected ties to China has been found targeting a Southeast Asian government to deploy spyware on Windows systems while staying under the radar for more than three years. "In this campaign, the attackers utilized the set of Microsoft Office exploits and loaders with anti-analysis and anti-debugging techniques to install a previously unknown backdoor on victim's machines," researchers from Check Point Research said in a report published today. The infection chain works by sending decoy documents, impersonating other entities within the government, to multiple members of the Ministry of Foreign Affairs, which, when opened, retrieves a next-stage payload from the attacker's server that contains an encrypted downloader. The downloader, in turn, gathers and exfiltrates system information to a remote server that subsequently responds back with a shellcode loader. The use of weaponized copies of legitimate-looking official doc

Days after  Microsoft ,  Secureworks , and  Volexity  shed light on a new spear-phishing activity unleashed by the Russian hackers who breached SolarWinds IT management software, the U.S. Department of Justice (DoJ) Tuesday said it intervened to take control of two command-and-control (C2) and malware distribution domains used in the campaign. The court-authorized domain seizure took place on May 28, the DoJ said, adding the action was aimed at disrupting the threat actors' follow-on exploitation of victims as well as block their ability to compromise new systems. The department, however, cautioned that the adversary might have deployed additional backdoor accesses in the interim period between when the initial compromises occurred, and the seizures took place last week. "[The] action is a continued demonstration of the Department's commitment to proactively disrupt hacking activity prior to the conclusion of a criminal investigation,"  said  Assistant Attorney Ge

Cybersecurity researchers have disclosed two new attack techniques on certified PDF documents that could potentially enable an attacker to alter a document's visible content by displaying malicious content over the certified content without invalidating its signature. "The attack idea exploits the flexibility of PDF certification, which allows signing or adding annotations to certified documents under different permission levels,"  said  researchers from Ruhr-University Bochum, who have  systematically   analyzed  the security of the PDF specification over the years. The findings were presented at the 42nd IEEE Symposium on Security and Privacy ( IEEE S&P 2021 ) held this week. The two attacks — dubbed  Evil Annotation and Sneaky Signature attacks  — hinge on manipulating the PDF certification process by exploiting flaws in the specification that governs the implementation of digital signatures (aka approval signature) and its more flexible variant called certifica

Cybersecurity researchers from FireEye unmasked additional tactics, techniques, and procedures (TTPs) adopted by Chinese threat actors who were recently found abusing Pulse Secure VPN devices to drop malicious web shells and exfiltrate sensitive information from enterprise networks. FireEye's Mandiant threat intelligence team, which is tracking the cyber espionage activity under two activity clusters UNC2630 and UNC2717,  said  the intrusions line up with key Chinese government priorities, adding "many compromised organizations operate in verticals and industries aligned with Beijing's strategic objectives outlined in China's recent  14th Five Year Plan ." On April 20, the cybersecurity firm  disclosed  12 different malware families, including STEADYPULSE and LOCKPICK, that have been designed with the express intent to infect Pulse Secure VPN appliances and put to use by at least two cyber espionage groups believed to be affiliated with the Chinese government.
