Cybersecurity researchers have disclosed two unpatched security vulnerabilities in the open-source U-Boot boot loader. The issues, which were uncovered in the IP defragmentation algorithm implemented in U-Boot by NCC Group, could be abused to achieve arbitrary out-of-bounds write and denial-of-service (DoS). U-Boot is a boot loader used in Linux-based embedded systems such as ChromeOS as

10 of the most prolific mobile banking trojans have set their eyes on 639 financial applications that are available on the Google Play Store and have been cumulatively downloaded over 1.01 billion times. Some of the most targeted apps include Walmart-backed PhonePe, Binance, Cash App, Garanti BBVA Mobile, La Banque Postale, Ma Banque, Caf –
Microsoft’s Digital Crimes Unit (DCU) last week disclosed that it had taken legal proceedings against an Iranian threat actor dubbed Bohrium in connection with a spear-phishing operation. The adversarial collective is said to have targeted entities in tech, transportation, government, and education sectors located in the U.S., Middle East, and India. “Bohrium actors create fake
A suspected state-aligned threat actor has been attributed to a new set of attacks exploiting the Microsoft Office “Follina” vulnerability to target government entities in Europe and the U.S. Enterprise security firm Proofpoint said it blocked attempts at exploiting the remote code execution flaw, which is being tracked CVE-2022-30190 (CVSS score: 7.8). No less than
Virtual Private Network (VPN) provider ExpressVPN on Thursday announced that it’s removing Indian-based VPN servers in response to a new cybersecurity directive issued by the Indian Computer Emergency Response Team (CERT-In). “Rest assured, our users will still be able to connect to VPN servers that will give them Indian IP addresses and allow them to
An analysis of leaked chats from the notorious Conti ransomware group earlier this year has revealed that the syndicate has been working on a set of firmware attack techniques that could offer a path to accessing privileged code on compromised devices. “Control over firmware gives attackers virtually unmatched powers both to directly cause damage and
Microsoft on Thursday said it took steps to disable malicious activity stemming from abuse of OneDrive by a previously undocumented threat actor it tracks under the chemical element-themed moniker Polonium. In addition to removing the offending accounts created by the Lebanon-based activity group, the tech giant’s Threat Intelligence Center (MSTIC) said it suspended over 20
Atlassian on Friday rolled out fixes to address a critical security flaw affecting its Confluence Server and Data Center products that have come under active exploitation by threat actors to achieve remote code execution. Tracked as CVE-2022-26134, the issue is similar to CVE-2021-26084 — another security flaw the Australian software company patched in August 2021.
An “extremely sophisticated” Chinese-speaking advanced persistent threat (APT) actor dubbed LuoYu has been observed using a malicious Windows tool called WinDealer that’s delivered by means of man-on-the-side attacks. “This groundbreaking development allows the actor to modify network traffic in-transit to insert malicious payloads,” Russian cybersecurity company Kaspersky said in a new report. “Such attacks are
GitLab has moved to address a critical security flaw in its service that, if successfully exploited, could result in an account takeover. Tracked as CVE-2022-1680, the issue has a CVSS severity score of 9.9 and was discovered internally by the company. The security flaw affects all versions of GitLab Enterprise Edition (EE) starting from 11.10
The Parrot traffic direction system (TDS) that came to light earlier this year has had a larger impact than previously thought, according to new research. Sucuri, which has been tracking the same campaign since February 2019 under the name “NDSW/NDSX,” said that “the malware was one of the top infections” detected in 2021, accounting for
Atlassian has warned of a critical unpatched remote code execution vulnerability impacting Confluence Server and Data Center products that it said is being actively exploited in the wild. The Australian software company credited cybersecurity firm Volexity for identifying the flaw, which is being tracked as CVE-2022-26134. “Atlassian has been made aware of current active exploitation
As the threat landscape evolves and multiplies with more advanced attacks than ever, defending against these modern cyber threats is a monumental challenge for almost any organization. Threat detection is about an organization’s ability to accurately identify threats, be it to the network, an endpoint, another asset or an application – including cloud infrastructure and
As ransomware infections have evolved from purely encrypting data to schemes such as double and triple extortion, a new attack vector is likely to set the stage for future campaigns. Called Ransomware for IoT or R4IoT by Forescout, it’s a “novel, proof-of-concept ransomware that exploits an IoT device to gain access and move laterally in
An international law enforcement operation involving 11 countries has culminated in the takedown of a notorious mobile malware threat called FluBot. “This Android malware has been spreading aggressively through SMS, stealing passwords, online banking details and other sensitive information from infected smartphones across the world,” Europol said in a statement. The “complex investigation” included authorities
A new unpatched security vulnerability has been disclosed in the open-source Horde Webmail client that could be exploited to achieve remote code execution on the email server simply by sending a specially crafted email to a victim. “Once the email is viewed, the attacker can silently take over the complete mail server without any further
An enhanced version of the XLoader malware has been spotted adopting a probability-based approach to camouflage its command-and-control (C&C) infrastructure, according to the latest research. “Now it is significantly harder to separate the wheat from the chaff and discover the real C&C servers among thousands of legitimate domains used by Xloader as a smokescreen,” Israeli
This is an exciting time for the Internet of Things. According to Deloitte research, the average U.S. household now has 25 connected devices — and new products are being launched every day. This rush of demand means that many tech companies are looking for developers with IoT knowledge. And even if you don’t want to
An analysis of the mobile threat landscape in 2022 shows that Spain and Turkey are the most targeted countries for malware campaigns, even as a mix of new and existing banking trojans are increasingly targeting Android devices to conduct on-device fraud (ODF). Other frequently targeted countries include Poland, Australia, the U.S., Germany, the U.K., Italy,
An “aggressive” advanced persistent threat (APT) group known as SideWinder has been linked to over 1,000 new attacks since April 2020. “Some of the main characteristics of this threat actor that make it stand out among the others, are the sheer number, high frequency and persistence of their attacks and the large collection of encrypted
Cybersecurity researchers are calling attention to a zero-day flaw in Microsoft Office that could be abused to achieve arbitrary code execution on affected Windows systems. The vulnerability came to light after an independent cybersecurity research team known as nao_sec uncovered a Word document (“05-2022-0438.doc“) that was uploaded to VirusTotal from an IP address in Belarus.
