The activity involves the exploitation of CVE-2025-20362 (CVSS score: 6.5) a...

Even in well-secured environments, attackers are getting in—not with flashy exploits, but by quietly taking advantage of weak settings, outdated encryption, and trusted tools left unprotected. These attacks don't depend on zero-days. They work by staying unnoticed—slipping through the cracks in what we monitor and what we assume is safe. What once looked suspicious now blends in, thanks to modular techniques and automation that copy normal behavior. The real concern? Control isn't just being challenged—it's being quietly taken. This week's updates highlight how default settings, blurred trust boundaries, and exposed infrastructure are turning everyday systems into entry points. ⚡ Threat of the Week Critical SharePoint Zero-Day Actively Exploited (Patch Released Today) — Microsoft has released fixes to address two security flaws in SharePoint Server that have come under active exploitation in the wild to breach dozens of organizations across the world. Details of exploitation emer...

Multiple Russia-aligned threat actors have been observed targeting individuals of interest via the privacy-focused messaging app Signal to gain unauthorized access to their accounts. "The most novel and widely used technique underpinning Russian-aligned attempts to compromise Signal accounts is the abuse of the app's legitimate 'linked devices' feature that enables Signal to be used on multiple devices concurrently," the Google Threat Intelligence Group (GTIG) said in a report. In the attacks spotted by the tech giant's threat intelligence teams, the threat actors, including one it's tracking as UNC5792, have resorted to malicious QR codes that, when scanned, will link a victim's account to an actor-controlled Signal instance. As a result, future messages get delivered synchronously to both the victim and the threat actor in real-time, thereby granting threat actors a persistent way to eavesdrop on the victim's conversations. Google said UNC5...

No fewer than 1,220 Man-in-the-Middle (MitM) phishing websites have been discovered as targeting popular online services like Instagram, Google, PayPal, Apple, Twitter, and LinkedIn with the goal of hijacking users' credentials and carrying out further follow-on attacks. The findings come from a  new study  undertaken by a group of researchers from Stony Brook University and Palo Alto Networks, who have demonstrated a new fingerprinting technique that makes it possible to identify MitM phishing kits in the wild by leveraging their intrinsic network-level properties, effectively automating the discovery and analysis of phishing websites. Dubbed " PHOCA " — named after the Latin word for "seals" — the tool not only facilitates the discovery of previously unseen MitM phishing toolkits, but also can be used to detect and isolate malicious requests coming from such servers. Phishing toolkits aim to  automate and streamline  the work required by attackers to cond...

An exhaustive analysis of  FIN7  has unmasked the cybercrime syndicate's organizational hierarchy, alongside unraveling its role as an affiliate for mounting ransomware attacks. It has also exposed deeper associations between the group and the larger threat ecosystem comprising the now-defunct ransomware  DarkSide ,  REvil , and  LockBit  families. The highly active threat group, also known as Carbanak, is  known  for employing an extensive arsenal of tools and tactics to expand its "cybercrime horizons," including adding ransomware to its playbook and setting up fake security companies to lure researchers into conducting ransomware attacks under the guise of penetration testing. More than 8,147 victims have been compromised by the financially motivated adversary across the world, with a majority of the entities located in the U.S. Other prominent countries include China, Germany, Canada, Italy, and the U.K. FIN7's intrusion techniques, over ...

A nascent threat actor known as Crypt Ghouls has been linked to a set of cyber attacks targeting Russian businesses and government agencies with ransomware with the twin goals of disrupting business operations and financial gain. "The group under review has a toolkit that includes utilities such as Mimikatz, XenAllPasswordPro, PingCastle, Localtonet, resocks, AnyDesk, PsExec, and others," Kaspersky said . "As the final payload, the group used the well-known ransomware LockBit 3.0 and Babuk." Victims of the malicious attacks span government agencies, as well as mining, energy, finance, and retail companies located in Russia. The Russian cybersecurity vendor said it was able to pinpoint the initial intrusion vector in only two instances, with the threat actors leveraging a contractor's login credentials to connect to the internal systems via VPN. The VPN connections are said to have originated from IP addresses associated with a Russian hosting provider...

Google's one-year-old cybersecurity venture Chronicle today announced its first commercial product, called Backstory , a cloud-based enterprise-level threat analytics platform that has been designed to help companies quickly investigate incidents, pinpoint vulnerabilities and hunt for potential threats. Network infrastructures at most enterprises regularly generate enormous amounts of network data and logs on a daily basis that can be helpful to figure out exactly what happened when a security incident occurs. However, unfortunately, most companies either don't collect the right telemetry or even when they do, it's practically impossible for them to retain that telemetry for more than a week or two, making analysts blind if any security incident happens before that. Backstory solves this problem by allowing organizations to privately upload and store their petabytes of "internal security telemetry" on Google cloud platform and leverage machine learning and da...

While there are apps that are more sensitive and complex to secu...

There are many different types of accounts in a typical Active Directory environment. These include user accounts, computer accounts, and a particular type of account called a  service account .  A service account is a special type of account that serves a specific purpose for services, and ultimately, applications in the environment. These special-purpose Active Directory accounts are also the subject of cybersecurity risks in the environment. What is a service account? What special privileges does it have on local systems? What cybersecurity risks can relate to service accounts used in the environment? How can IT admins find weak or non-expiring passwords used in Active Directory for service accounts? What is a Windows service? As mentioned at the outset, specific Active Directory accounts serve different purposes in Active Directory Domain Services (ADDS). You can assign Active Directory accounts as service accounts, a special-purpose account that most organizations c...
