Security researchers have disclosed two new vulnerabilities affecting Schneider Electric Modicon programmable logic controllers (PLCs) that could allow for authentication bypass and remote code execution. The flaws, tracked as  CVE-2022-45788  (CVSS score: 7.5) and  CVE-2022-45789  (CVSS score: 8.1), are part of a  broader collection  of  security defects  tracked by Forescout as OT:ICEFALL. Successful exploitation of the bugs could enable an adversary to execute unauthorized code, denial-of-service, or disclosure of sensitive information. The cybersecurity company said the shortcomings can be chained by a threat actor with known flaws from other vendors (e.g.,  CVE-2021-31886 ) to achieve deep lateral movement in operational technology (OT) networks. "Deep lateral movement lets attackers gain deep access to industrial control systems and cross often overlooked security perimeters, allowing them to perform highly granular and stealthy ...

Security teams typically have great visibility over most areas, for example, the corporate network, endpoints, servers, and cloud infrastructure. They use this visibility to enforce the necessary security and compliance requirements. However, this is not the case when it comes to sensitive data sitting in production or analytic databases, data warehouses or data lakes. Security teams have to rely on data teams to locate sensitive data and enforce access controls and security policies. This is a huge headache for both the security and data teams. It weakens the business's security and compliance putting it at risk of exposing sensitive data, large fines, reputational damages, and more. Also, in many cases, it slows down the business's ability to scale up data operations.  This article examines how Satori, a data security platform, gives control of the sensitive data in databases, data warehouses and data lakes to the security teams. Satori's  automated data security plat...

Telecommunication service providers in the Middle East are being targeted by a previously undocumented threat actor as part of a suspected intelligence gathering mission. Cybersecurity firms SentinelOne and QGroup are tracking the activity cluster under the former's work-in-progress moniker  WIP26 . "WIP26 relies heavily on public cloud infrastructure in an attempt to evade detection by making malicious traffic look legitimate," researchers Aleksandar Milenkoski, Collin Farr, and Joey Chen  said  in a report shared with The Hacker News. This includes the misuse of Microsoft 365 Mail, Azure, Google Firebase, and Dropbox for malware delivery, data exfiltration, and command-and-control (C2) purposes. The initial intrusion vector used in the attacks entails "precision targeting" of employees via WhatsApp messages that contain links to Dropbox links to supposedly benign archive files. The files, in reality, harbor a malware loader whose core feature is to depl...

More than 500 hosts have been newly compromised en masse by the ESXiArgs ransomware strain, most of which are located in France, Germany, the Netherlands, the U.K., and Ukraine. The  findings  come from attack surface management firm Censys, which  discovered  "two hosts with strikingly similar ransom notes dating back to mid-October 2022, just after ESXi versions 6.5 and 6.7 reached end of life." The first set of infections dates back to October 12, 2022, much earlier than when the campaign  began to gain traction  at the start of February 2023. Then on January 31, 2023, the ransom notes on the two hosts are said to have been updated with a revised version that matches the ones used in the current wave. Some of the crucial differences between the two ransom notes include the use of an onion URL instead of a Tox chat ID, a Proton Mail address at the bottom of the note, and a lower ransom demand (1.05 Bitcoin vs. 2.09 Bitcoin). "Each variant of the ran...

The North Korea-linked threat actor tracked as  APT37  has been linked to a piece of new malware dubbed  M2RAT  in attacks targeting its southern counterpart, suggesting continued evolution of the group's features and tactics. APT37, also tracked under the monikers Reaper, RedEyes, Ricochet Chollima, and ScarCruft, is an element within North Korea's Ministry of State Security (MSS) unlike the Lazarus and Kimsuky threat clusters that are part of the Reconnaissance General Bureau (RGB). According to Google-owned Mandiant, MSS is tasked with "domestic counterespionage and overseas counterintelligence activities," with APT37's attack campaigns reflective of the agency's priorities. The operations have historically singled out individuals such as defectors and human rights activists. "APT37's assessed primary mission is covert intelligence gathering in support of DPRK's strategic military, political, and economic interests," the threat intelli...

Bad actors love to deliver threats in files. Persistent and persuasive messages convince unsuspecting victims to accept and open files from unknown sources, executing the first step in a cyber attack.  This continues to happen whether the file is an EXE or a Microsoft Excel document. Far too often, end users have an illusion of security, masked by good faith efforts of other users and (ineffective) security controls. This creates a virality effect for ransomware, malware, spyware, and annoying grayware and adware to be spread easily from user to user and machine to machine. To stop users from saying, "I reject your reality and substitute my own!" – it's time to bust some myths about file-based attacks.  Testing in three! Two!

A new financially motivated campaign that commenced in December 2022 has seen the unidentified threat actor behind it deploying a novel ransomware strain dubbed MortalKombat and a clipper malware known as Laplas. Cisco Talos  said  it "observed the actor scanning the internet for victim machines with an exposed remote desktop protocol (RDP) port 3389." The attacks, per the cybersecurity company, primarily focuses on individuals, small businesses, and large organizations located in the U.S., and to a lesser extent in the U.K., Turkey, and the Philippines. The starting point that kicks off the multi-stage attack chain is a phishing email bearing a malicious ZIP file that's used as a pathway to deliver either the clipper or the ransomware. In addition to using cryptocurrency-themed email lures impersonating CoinPayments, the threat actor is also known to erase infection markers in an attempt to cover its tracks. MortalKombat, first detected in January 2023, is capable...

In an ideal world, security and development teams would be working together in perfect harmony. But we live in a world of competing priorities, where DevOps and security departments often butt heads with each other. Agility and security  are often at odds with each other— if a new feature is  delivered quickly but  contains security vulnerabilities, the SecOps team will need to scramble the release and patch the vulnerabilities, which can take days or weeks. On the other hand, if the SecOps team takes too long to review and approve a new feature, the development team will get frustrated with the slow pace of delivery. Security needs to move slowly and cautiously, while development wants to "move fast and break things" and release new features quickly. DevOps teams can view security as an impediment to their work instead of an important part of the process. With each team pulling in opposite directions, there is often tension and conflict between the two teams, slowing ...

Cybersecurity researchers have unearthed a new piece of evasive malware dubbed  Beep  that's designed to fly under the radar and drop additional payloads onto a compromised host. "It seemed as if the authors of this malware were trying to implement as many anti-debugging and anti-VM (anti-sandbox) techniques as they could find," Minerva Labs researcher Natalie Zargarov  said . "One such technique involved delaying execution through the use of the  Beep API function , hence the malware's name." Beep comprises three components, the first of which is a dropper that's responsible for creating a new Windows Registry key and executing a Base64-encoded PowerShell script stored in it. The PowerShell script, for its part, reaches out to a remote server to retrieve an injector, which, after confirming it's not being debugged or launched in a virtual machine, extracts and launches the payload via a technique called  process hollowing . The payload is an ...
