Google has stepped in to remove a bogus Chrome browser extension from the official Web Store that masqueraded as OpenAI's ChatGPT service to harvest Facebook session cookies and hijack the accounts. The "ChatGPT For Google" extension, a trojanized version of a  legitimate open source browser add-on , attracted over 9,000 installations since March 14, 2023, prior to its removal. It was originally uploaded to the Chrome Web Store on February 14, 2023. According to  Guardio Labs  researcher Nati Tal, the extension was propagated through  malicious   sponsored Google search results  that were designed to redirect unsuspecting users searching for "Chat GPT-4" to fraudulent landing pages that point to the fake add-on. Installing the extension adds the promised functionality – i.e., enhancing search engines with ChatGPT – but it also stealthily activates the ability to capture Facebook-related cookies and exfiltrate it to a remote server in an encrypted manner.

An emerging Android banking trojan dubbed  Nexus  has already been adopted by several threat actors to target 450 financial applications and conduct fraud. "Nexus appears to be in its early stages of development," Italian cybersecurity firm Cleafy  said  in a report published this week. "Nexus provides all the main features to perform ATO attacks (Account Takeover) against banking portals and cryptocurrency services, such as credentials stealing and SMS interception." The trojan, which appeared in various hacking forums at the start of the year, is advertised as a subscription service to its clientele for a monthly fee of $3,000. Details of the malware were  first documented  by Cyble earlier this month. However, there are indications that the malware may have been used in real-world attacks as early as June 2022, at least six months before its official announcement on darknet portals. According to security researcher Rohit Bansal ( @0xrb ) and confirmed by t

When it comes to ensuring the security of your APIs, there are four critical capabilities.

In 2022 alone, global cyberattacks increased by 38%, resulting in substantial business loss, including financial and reputational damage. Meanwhile, corporate security budgets have risen significantly because of the growing sophistication of attacks and the number of cybersecurity solutions introduced into the market. With this rise in threats, budgets, and solutions, how prepared are industries and countries to effectively address today's cyber risk?  CYE's new  Cybersecurity Maturity Report 2023  tackles this question by shedding light on the strength of cybersecurity in different sectors, company sizes, and countries. It highlights which industries and countries have the most robust cyber postures and which are lagging, as well as the most prevalent vulnerabilities in today's cyber threat landscape. The analysis is based on two years' worth of data, collected from over 500 organizations in 15 countries, and spanning 11 industries and a range of company sizes. It measures cybersec

Telecommunication providers in the Middle East are the subject of new cyber attacks that commenced in the first quarter of 2023. The intrusion set has been attributed to a Chinese cyber espionage actor associated with a long-running campaign dubbed  Operation Soft Cell  based on tooling overlaps. "The initial attack phase involves infiltrating Internet-facing Microsoft Exchange servers to deploy web shells used for command execution," researchers from SentinelOne and QGroup said in a  new technical report  shared with The Hacker News. "Once a foothold is established, the attackers conduct a variety of reconnaissance, credential theft, lateral movement, and data exfiltration activities." Operation Soft Cell, according to  Cybereason , refers to malicious activities undertaken by China-affiliated actors targeting telecommunications providers since at least 2012. The Soft Cell threat actor, also tracked by Microsoft as  Gallium , is known to target unpatched int

German and South Korean government agencies have warned about cyber attacks mounted by a threat actor tracked as  Kimsuky  using rogue browser extensions to steal users' Gmail inboxes. The  joint advisory   comes  from Germany's domestic intelligence apparatus, the Federal Office for the Protection of the Constitution (BfV), and South Korea's National Intelligence Service of the Republic of Korea (NIS). The intrusions are designed to strike "experts on the Korean Peninsula and North Korea issues" through spear-phishing campaigns, the agencies noted. Kimsuky , also known Black Banshee, Thallium, and Velvet Chollima, refers to a  subordinate element  within North Korea's Reconnaissance General Bureau and is known to "collect strategic intelligence on geopolitical events and negotiations affecting the DPRK's interests." Primary targets of interest include entities in the U.S. and South Korea, particularly singling out individuals working within

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has released eight Industrial Control Systems (ICS)  advisories  on Tuesday, warning of critical flaws affecting equipment from Delta Electronics and Rockwell Automation. This includes 13 security vulnerabilities in Delta Electronics' InfraSuite Device Master, a real-time device monitoring software. All versions prior to 1.0.5 are affected by the issues. "Successful exploitation of these vulnerabilities could allow an unauthenticated attacker to obtain access to files and credentials, escalate privileges, and remotely execute arbitrary code," CISA  said . At the top of the list is  CVE-2023-1133  (CVSS score: 9.8), a critical flaw that arises from the fact that InfraSuite Device Master accepts unverified UDP packets and  deserializes the content , thereby allowing an unauthenticated remote attacker to execute arbitrary code. Two other deserialization flaws,  CVE-2023-1139  (CVSS score: 8.8) and  CVE-20

The North Korean advanced persistent threat (APT) actor dubbed ScarCruft is using weaponized Microsoft Compiled HTML Help (CHM) files to download additional malware onto targeted machines. According to multiple reports from  AhnLab Security Emergency response Center  ( ASEC ),  SEKOIA.IO , and  Zscaler , the development is illustrative of the group's continuous efforts to refine and retool its tactics to sidestep detection. "The group is constantly evolving its tools, techniques, and procedures while experimenting with new file formats and methods to bypass security vendors," Zscaler researchers Sudeep Singh and Naveen Selvan said in a new analysis published Tuesday.  ScarCruft, also tracked under the names APT37, Reaper, RedEyes, and Ricochet Chollima, has exhibited an increased operational tempo since the start of the year, targeting various South Korean entities for espionage purposes. It is known to be active since at least 2012. Last month, ASEC  disclosed  a

Active Directory (AD) is a powerful authentication and directory service used by organizations worldwide. With this ubiquity and power comes the potential for abuse. Insider threats offer some of the most potentials for destruction. Many internal users have over-provisioned access and visibility into the internal network. Insiders' level of access and trust in a network leads to unique vulnerabilities. Network security often focuses on keeping a threat actor out, not on existing users' security and potential vulnerabilities. Staying on top of potential threats means protecting against inside and outside threats. Active Directory Vulnerabilities From the outside, a properly configured AD domain offers a secure authentication and authorization solution. But with complex social engineering and phishing email attacks, an existing AD user can become compromised. Once inside, threat actors have many options to attack Active Directory. Insecure Devices With "Bring Your Own

The  NuGet  repository is the target of a new "sophisticated and highly-malicious attack" aiming to infect .NET developer systems with cryptocurrency stealer malware. The 13 rogue packages, which were downloaded more than 160,000 times over the past month, have since been taken down. "The packages contained a PowerShell script that would execute upon installation and trigger a download of a 'second stage' payload, which could be remotely executed," JFrog researchers Natan Nehorai and Brian Moussalli  said . While NuGet packages have been in the past found to  contain vulnerabilities  and be abused to  propagate phishing links , the development marks the first-ever discovery of packages with malicious code. Three of the most downloaded packages – Coinbase.Core, Anarchy.Wrapper.Net, and DiscordRichPresence.API – alone accounted for 166,000 downloads, although it's also possible that the threat actors artificially inflated the download counts using bo
