The National Institute of Standards and Technology (NIST) had published a document on Jan 2011 that the SHA-1 algorithm will be risky and should be disallowed after year 2013, but it was recently noticed by Netcraft experts that NIST.gov website itself were using 2014 dated SSL certificate with SHA-1 hashes. " From January 1, 2011 through December 31, 2013, the use of SHA-1 is deprecated for digital signature generation. The user must accept risk when SHA-1 is used, particularly when approaching the December 31, 2013 upper limit. SHA-1 shall not be used for digital signature generation after December 31, 2013. " NIST in the document. Digital signatures facilitate the safe exchange of electronic documents by providing a way to test both the authenticity and the integrity of information exchanged digitally. Authenticity means when you sign data with a digital signature, someone else can verify the signature, and can confirm that the data originated from you and was not...

Here's a hard question to answer: 'How many service accounts do you have in your environment?'. A harder one is: 'Do you know what these accounts are doing?'. And the hardest is probably: 'If any of your service account was compromised and used to access resources would you be able to detect and stop that in real-time?'.  Since most identity and security teams would provide a negative reply, it's no wonder that  one of the immediate actions today's attackers are doing following an initial endpoint compromised is hunting down unwatched service accounts.  And it's even less of a wonder that in most cases, they would succeed in finding one and leveraging it to spread within the entire environment, getting noticed only when it's too late – after workstations and server got encrypted by ransomware or sensitive data was stolen.  In this article, we unfold the reasons that have caused service accounts to become one of the most dangerous weaknesse...

Despite a plethora of available security solutions, more and more organizations fall victim to Ransomware and other threats. These continued threats aren't just an inconvenience that hurt businesses and end users - they damage the economy, endanger lives, destroy businesses and put national security at risk. But if that wasn’t enough – North Korea appears to be  using revenue from cyber attacks to funds its nuclear weapons program . Small and mid-size businesses are increasingly caught in the dragnet of ongoing malware attacks - often due to underfunded IT departments. Exacerbating the problem are complex enterprise security solutions that are often out of reach for many companies - especially when multiple products are seemingly needed to establish a solid defense. Volume-based products that incentivize users to collect less data in order to conserve funds work backward, dampening the anticipated benefits. But what if you could detect many malware attacks holistically with ...

SonicWall said it's actively investigating reports to determine if there is a new zero-day vulnerability following reports of a spike in Akira ransomware actors in late July 2025. "Over the past 72 hours, there has been a notable increase in both internally and externally reported cyber incidents involving Gen 7 SonicWall firewalls where SSLVPN is enabled," the network security vendor said in a statement Monday. "We are actively investigating these incidents to determine whether they are connected to a previously disclosed vulnerability or if a new vulnerability may be responsible." While SonicWall is digging deeper, organizations using Gen 7 SonicWall firewalls are advised to follow the steps below until further notice - Disable SSL VPN services where practical Limit SSL VPN connectivity to trusted IP addresses Activate services such as Botnet Protection and Geo-IP Filtering Enforce multi-factor authentication Remove inactive or unused local user ac...

Some of the biggest security problems start quietly. No alerts. No warnings. Just small actions that seem normal but aren't. Attackers now know how to stay hidden by blending in, and that makes it hard to tell when something’s wrong. This week’s stories aren’t just about what was attacked—but how easily it happened. If we’re only looking for the obvious signs, what are we missing right in front of us? Here’s a look at the tactics and mistakes that show how much can go unnoticed. ⚡ Threat of the Week Apple Zero-Click Flaw in Messages Exploited to Deliver Paragon Spyware — Apple disclosed that a security flaw in its Messages app was actively exploited in the wild to target civil society members in sophisticated cyber attacks. The vulnerability, CVE-2025-43200, was addressed by the company in February as part of iOS 18.3.1, iPadOS 18.3.1, iPadOS 17.7.5, macOS Sequoia 15.3.1, macOS Sonoma 14.7.4, macOS Ventura 13.7.4, watchOS 11.3.1, and visionOS 2.3.1. The Citizen Lab said it u...

Stopping new and evasive threats is one of the greatest challenges in cybersecurity. This is among the biggest reasons why  attacks increased dramatically in the past year  yet again, despite the estimated $172 billion spent on global cybersecurity in 2022. Armed with cloud-based tools and backed by sophisticated affiliate networks, threat actors can develop new and evasive malware more quickly than organizations can update their protections.  Relying on malware signatures and blocklists against these rapidly changing attacks has become futile. As a result, the SOC toolkit now largely revolves around threat detection and investigation. If an attacker can bypass your initial blocks, you expect your tools to pick them up at some point in the attack chain. Every organization's digital architecture is now seeded with security controls that log anything potentially malicious. Security analysts pore through these logs and determine what to investigate further. Does this wor...

Microsoft Windows 10 and Windows 11 users are at risk of a new unpatched vulnerability that was recently disclosed publicly. As we reported last week, the vulnerability — SeriousSAM — allows attackers with low-level permissions to access Windows system files to perform a Pass-the-Hash (and potentially Silver Ticket) attack.  Attackers can exploit this vulnerability to obtain hashed passwords stored in the Security Account Manager (SAM) and Registry, and ultimately run arbitrary code with SYSTEM privileges. SeriousSAM vulnerability, tracked as CVE-2021-36934 , exists in the default configuration of Windows 10 and Windows 11, specifically due to a setting that allows 'read' permissions to the built-in user's group that contains all local users. As a result, built-in local users have access to read the SAM files and the Registry, where they can also view the hashes. Once the attacker has 'User' access, they can use a tool such as Mimikatz to gain access to the Re...

Ever wonder what happens in the digital world every time you blink? Here's something wild - hackers launch about 2,200 attacks every single day, which means someone's trying to break into a system somewhere every 39 seconds. And get this - while we're all worried about regular hackers, there are now AI systems out there that can craft phishing emails so convincingly, that even cybersecurity experts have trouble spotting them. What's even crazier? Some of the latest malware is like a digital chameleon - it literally watches how you try to catch it and changes its behavior to slip right past your defenses. Pretty mind-bending stuff, right? This week's roundup is packed with eye-opening developments that'll make you see your laptop in a whole new light. ⚡ Threat of the Week T-Mobile Spots Hackers Trying to Break In: U.S. telecom service provider T-Mobile caught some suspicious activity on their network recently - basically, someone was trying to sneak into th...
