High-Severity Flaws Uncovered in Bosch Thermostats and Smart Nutrunners

High-Severity Flaws Uncovered in Bosch Thermostats and Smart Nutrunners

Jan 15, 2024 Operational Technology / Network Security
Multiple security vulnerabilities have been disclosed in Bosch BCC100 thermostats and Rexroth NXA015S-36V-B smart nutrunners that, if successfully exploited, could allow attackers to execute arbitrary code on affected systems. Romanian cybersecurity firm Bitdefender, which  discovered  the flaw in Bosch BCC100 thermostats last August, said the issue could be weaponized by an attacker to alter the device firmware and implant a rogue version. Tracked as  CVE-2023-49722  (CVSS score: 8.3), the high-severity vulnerability was addressed by Bosch in November 2023. "A network port 8899 is always open in BCC101/BCC102/BCC50 thermostat products, which allows an unauthenticated connection from a local WiFi network," the company  said  in an advisory. The issue, at its core, impacts the WiFi microcontroller that acts as a network gateway for the thermostat's logic microcontroller. By exploiting the flaw, an attacker could send commands to the thermostat, includ...

Balada Injector Infects Over 7,100 WordPress Sites Using Plugin Vulnerability

Jan 15, 2024 Website Security / Vulnerability
Thousands of WordPress sites using a vulnerable version of the Popup Builder plugin have been compromised with a malware called  Balada Injector . First  documented  by Doctor Web in January 2023, the campaign takes place in a series of periodic attack waves, weaponizing security flaws in WordPress plugins to inject backdoor designed to redirect visitors of infected sites to bogus tech support pages, fraudulent lottery wins, and push notification scams. Subsequent  findings  unearthed by Sucuri have revealed the  massive scale of the operation , which is said to have been active since 2017 and infiltrated no less than 1 million sites since then. The GoDaddy-owned website security company, which  detected  the latest Balada Injector activity on December 13, 2023, said it identified the injections on  over 7,100 sites . These attacks take advantage of a high-severity flaw in Popup Builder ( CVE-2023-6000 , CVSS score: 8.8) – a plugin with...
DDoS Attacks on the Environmental Services Industry Surge by 61,839% in 2023

DDoS Attacks on the Environmental Services Industry Surge by 61,839% in 2023

Jan 15, 2024 Server Security / Cyber Attack
The environmental services industry witnessed an "unprecedented surge" in HTTP-based distributed denial-of-service (DDoS) attacks, accounting for half of all its HTTP traffic. This marks a 61,839% increase in DDoS attack traffic year-over-year, web infrastructure and security company Cloudflare said in its DDoS threat report for 2023 Q4 published last week. "This surge in cyber attacks coincided with  COP 28 , which ran from November 30th to December 12th, 2023," security researchers Omer Yoachimik and Jorge Pacheco  said , describing it as a "disturbing trend in the cyber threat landscape." The uptick in HTTP attacks targeting environmental services websites is part of a larger trend observed annually over the past few years, specifically during COP 26 and COP 27, as well as other United Nations environment-related resolutions or announcements. "This recurring pattern underscores the growing intersection between environmental issues and cyber security, a nexus that is in...

The Hidden Risks of SaaS: Why Built-In Protections Aren't Enough for Modern Data Resilience

The Hidden Risks of SaaS: Why Built-In Protections Aren't Enough for Modern Data Resilience

Jun 26, 2025Data Protection / Compliance
SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...
New Findings Challenge Attribution in Denmark's Energy Sector Cyberattacks

New Findings Challenge Attribution in Denmark's Energy Sector Cyberattacks

Jan 14, 2024 Cyber Attack / Vulnerability
The cyber attacks targeting the energy sector in Denmark last year may not have had the involvement of the Russia-linked Sandworm hacking group,  new findings  from Forescout show. The intrusions, which  targeted around 22 Danish energy organizations  in May 2023, occurred in two distinct waves, one which exploited a security flaw in Zyxel firewall (CVE-2023-28771) and a follow-on activity cluster that saw the attackers deploy Mirai botnet variants on infected hosts via an as-yet-unknown initial access vector. The first wave took place on May 11, while the second wave lasted from May 22 to 31, 2023. In one such attack detected on May 24, it was observed that the compromised system was communicating with IP addresses (217.57.80[.]18 and 70.62.153[.]174) that were previously used as command-and-control (C2) for the now-dismantled  Cyclops Blink  botnet. Forescout's closer examination of the attack campaign, however, has revealed that not only were the t...

Critical RCE Vulnerability Uncovered in Juniper SRX Firewalls and EX Switches

Jan 13, 2024 Vulnerability / Network Security
Juniper Networks has released updates to fix a critical remote code execution (RCE) vulnerability in its SRX Series firewalls and EX Series switches. The issue, tracked as  CVE-2024-21591 , is rated 9.8 on the CVSS scoring system. "An out-of-bounds write vulnerability in J-Web of Juniper Networks Junos OS SRX Series and EX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS) or Remote Code Execution (RCE) and obtain root privileges on the device," the company  said  in an advisory. The networking equipment major, which is set to be  acquired by Hewlett Packard Enterprise (HPE)  for $14 billion, said the issue is caused by use of an insecure function allowing a bad actor to overwrite arbitrary memory. The flaw impacts the following versions, and has been fixed in versions 20.4R3-S9, 21.2R3-S7, 21.3R3-S5, 21.4R3-S5, 22.1R3-S4, 22.2R3-S3, 22.3R3-S2, 22.4R2-S2, 22.4R3, 23.2R1-S1, 23.2R2, 23.4R1, and later - Junos OS ver...

29-Year-Old Ukrainian Cryptojacking Kingpin Arrested for Exploiting Cloud Services

Jan 13, 2024 Cryptojacking / Cloud Security
A 29-year-old Ukrainian national has been arrested in connection with running a "sophisticated cryptojacking scheme," netting them over $2 million (€1.8 million) in illicit profits. The person, described as the "mastermind" behind the operation, was apprehended in Mykolaiv, Ukraine, on January 9 by the National Police of Ukraine with support from Europol and an unnamed cloud service provider following "months of intensive collaboration." "A cloud provider approached Europol back in January 2023 with information regarding compromised cloud user accounts of theirs," Europol  said , adding it shared the intelligence with the Ukrainian authorities. The Cyber Police of Ukraine, in a separate announcement, said the suspect "infected the servers of a well-known American company with a miner virus" at least since 2021, using custom brute-force tools to infiltrate 1,500 accounts of the firm. "Using the compromised accounts, the hacker gained access to the management ...
Nation-State Actors Weaponize Ivanti VPN Zero-Days, Deploying 5 Malware Families

Nation-State Actors Weaponize Ivanti VPN Zero-Days, Deploying 5 Malware Families

Jan 12, 2024 Vulnerability / Threat Intelligence
As many as five different malware families were deployed by suspected nation-state actors as part of post-exploitation activities leveraging  two zero-day vulnerabilities  in Ivanti Connect Secure (ICS) VPN appliances since early December 2023. "These families allow the threat actors to circumvent authentication and provide backdoor access to these devices," Mandiant  said  in an analysis published this week. The Google-owned threat intelligence firm is tracking the threat actor under the moniker  UNC5221 .  The attacks leverage an exploit chain comprising an authentication bypass flaw (CVE-2023-46805) and a code injection vulnerability (CVE-2024-21887) to take over susceptible instances. Volexity, which attributed the activity to a suspected Chinese espionage actor named UTA0178, said the twin flaws were used to gain initial access, deploy webshells, backdoor legitimate files, capture credentials and configuration data, and pivot further into the vict...
Medusa Ransomware on the Rise: From Data Leaks to Multi-Extortion

Medusa Ransomware on the Rise: From Data Leaks to Multi-Extortion

Jan 12, 2024 Ransomware / Dark Web
The threat actors associated with the  Medusa ransomware  have ramped up their activities following the debut of a dedicated data leak site on the dark web in February 2023 to publish sensitive data of victims who are unwilling to agree to their demands. "As part of their multi-extortion strategy, this group will provide victims with multiple options when their data is posted on their leak site, such as time extension, data deletion or download of all the data," Palo Alto Networks Unit 42 researchers Anthony Galiette and Doel Santos  said  in a report shared with The Hacker News. "All of these options have a price tag depending on the organization impacted by this group." Medusa (not to be confused with Medusa Locker) refers to a ransomware family that appeared in late 2022 before coming into prominence in 2023. It's known for opportunistically targeting a wide range of industries such as high technology, education, manufacturing, healthcare, and retail. As many...
Applying the Tyson Principle to Cybersecurity: Why Attack Simulation is Key to Avoiding a KO

Applying the Tyson Principle to Cybersecurity: Why Attack Simulation is Key to Avoiding a KO

Jan 12, 2024 Breach and Attack Simulation
Picture a cybersecurity landscape where defenses are impenetrable, and threats are nothing more than mere disturbances deflected by a strong shield. Sadly, this image of fortitude remains a pipe dream despite its comforting nature. In the security world, preparedness is not just a luxury but a necessity. In this context, Mike Tyson's famous adage, "Everyone has a plan until they get punched in the face," lends itself to our arena - cyber defenses must be battle-tested to stand a chance. Tyson's words capture the paradox of readiness in cybersecurity: too often, untested cyber defenses can create a false sense of security, leading to dire consequences when real threats land a blow. This is where Breach and Attack Simulation (BAS), a proactive tool in any organization's cybersecurity arsenal, comes into play. When Cybersecurity Meets the Punch - The Assumption Problem Assumptions are the hidden icebergs in cybersecurity's vast ocean. Although we might believ...
