Cybersecurity researchers today revealed the existence of a new and previously undetected critical vulnerability in SIM cards that could allow remote attackers to compromise targeted mobile phones and spy on victims just by sending an SMS. Dubbed " SimJacker ," the vulnerability resides in a particular piece of software, called the S@T Browser (a dynamic SIM toolkit), embedded on most SIM cards that is widely being used by mobile operators in at least 30 countries and can be exploited regardless of which handsets victims are using. What's worrisome? A specific private company that works with governments is actively exploiting the SimJacker vulnerability from at least the last two years to conduct targeted surveillance on mobile phone users across several countries. S@T Browser , short for SIMalliance Toolbox Browser, is an application that comes installed on a variety of SIM cards, including eSIM, as part of SIM Tool Kit (STK) and has been designed to let mobile

Update —  After reading this article, if you want to know, what has happened so far in past 4 days and how to protect your computers from WannaCry, read our latest article " WannaCry Ransomware: Everything You Need To Know Immediately . "  If you are following the news, by now you might be aware that a security researcher has activated a "Kill Switch" which apparently stopped the WannaCry ransomware from spreading further. But it's not true, neither the threat is over yet. However, the kill switch has just slowed down the infection rate. Updated:  Multiple security researchers have claimed that there are more samples of WannaCry out there, with different 'kill-switch' domains and without any kill-switch function, continuing to infect unpatched computers worldwide (find more details below). So far, over 237,000 computers across 99 countries around the world have been infected, and the infection is still rising even hours after the kill swit

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

We distilled 30 independent reports dedicated to cybersecurity and cybercrime predictions for 2020 and compiled the top 5 most interesting findings and projections in this post. Compliance fatigue will spread among security professionals Being a source of ongoing controversy and debate, the California Consumer Privacy Act (CCPA) was finalized on 11th January 1, 2019. Driven by laudable objectives to protect Californians' personal data, prevent its misuse or unconsented usage by unscrupulous entities, the law imposes formidable monetary penalties of up to $7,500 per intentional violation and $2,500 per unintentional violation. The Act is enforceable against organizations that process or handle personal data of California residents, regardless of the geographical location of the former. Akin to the EU GDPR, data subjects are empowered with a bundle of rights to control their personal data and its eventual usage. The pitfall is that if every US state introduces its own s

In today's world your network is subject to a multitude of vulnerabilities and potential intrusions and it seems like we see or hear of a new attack weekly. A data breach is arguably the most costly and damaging of these attacks and while loss of data is painful the residual impact of the breach is even more costly. The loss or leakage of sensitive data can result in serious damage to an organization, including: Loss of intellectual property Loss of copyrighted information Compliance violations Damage to corporate reputation/brand Loss of customer loyalty Loss of future business opportunities Lawsuits and ongoing litigation Financial and criminal penalties To help you protect sensitive data and reduce the risk of data loss, we recommend using a Security Information and Event Management ( SIEM ) technology such as SolarWinds® Log & Event Manager . If you're not familiar with Log & Event Manager (LEM), it's a comprehensive SIEM product, packaged in an ea

In last year's edition of the  Security Navigator  we noted that the Manufacturing Industry appeared to be totally over-represented in our dataset of Cyber Extortion victims. Neither the number of businesses nor their average revenue particularly stood out to explain this. Manufacturing was also the most represented Industry in our CyberSOC dataset – contributing more Incidents than any other sector.  We found this trend confirmed in 2023 – so much in fact that we decided to take a closer look. So let's examine some possible explanations.  And debunk them. Hunting for possible explanations Manufacturing is still the most impacted industry in our Cyber Extortion dataset in 2023, as tracked by monitoring double-extortion leak sites. Indeed, this sector now represents more than 20% of all victims since we started observing the leak sites in the beginning of 2020. Approximately 28% of all our clients are from Manufacturing, contributing with an overall share of 31% of all p

In Part I of this  two-part series from The Hacker News , the First Four list of Top Brutal Cyber Attacks shows that whoever you are, Security can never be perfect. As attackers employ innovative hacking techniques and zero-day exploits, the demand for increased threat protection grows. In this article, I have listed another three cyber attacks, as following: #5 Car Hacking Driving a car is a network's game now! ' Everything is hackable ,' but is your car also vulnerable to Hackers ? General Motors' OnStar application and cars like Jeep Cherokee, Cadillac Escalade, Toyota Prius, Dodge Viper, Audi A8 and many more come equipped with more advanced technology features. These cars are now part of the technology very well known as the " Internet of Things ". Recently two Security researchers, Chris Valasek and Charlie Miller demonstrated that Jeep Cherokee could be hacked wirelessly over the internet to hijack its steering, brakes, and transmi

Introduced in 1999, Microsoft Active Directory is the default identity and access management service in Windows networks, responsible for assigning and enforcing security policies for all network endpoints. With it, users can access various resources across networks. As things tend to do, times, they are a'changin' – and a few years back, Microsoft introduced Azure Active Directory, the cloud-based version of AD to extend the AD paradigm, providing organizations with an Identity-as-a-Service (IDaaS) solution across both the cloud and on-prem apps. (Note that as of July 11th 2023, this service was renamed to  Microsoft Entra ID , but for the sake of simplicity, we'll refer to it as Azure AD in this post) Both Active Directory and Azure AD are critical to the functioning of on-prem, cloud-based, and hybrid ecosystems, playing a key role in uptime and business continuity. And with 90% of organizations using the service for employee authentication, access control and ID manag

No business is out of danger of cyberattacks today. However, specific industries are particularly at risk and a favorite of attackers. For years, the healthcare industry has taken the brunt of ransomware attacks, data breaches, and other cyberattacks. Why is the healthcare industry particularly at risk for a cyberattack? What are the unique challenges to cybersecurity in healthcare, and how can healthcare organizations address these? Healthcare at risk Attackers are targeting various industries across the board. However, attackers seem to have a particular affinity for healthcare organizations. For eleven consecutive years, in the  IBM Cost of a Data Breach Report 2021 , healthcare had the highest industry cost of a breach. Additionally, Healthcare data breach costs increased from an average total cost of $7.13 million in 2020 to $9.23 million in 2021, a 29.5% increase. However, the tremendous cost sustained by healthcare organizations for data breach events is not only due to the

Google has made several new announcements for its Chrome Web Store that aims at making Chrome extensions more secure and transparent to its users. Over a couple of years, we have seen a significant rise in malicious extensions that appear to offer useful functionalities, while running hidden malicious scripts in the background without the user's knowledge. However, the best part is that Google is aware of the issues and has proactively been working to change the way its Chrome web browser handles extensions. Earlier this year, Google banned extensions using cryptocurrency mining scripts and then in June, the company also disabled inline installation of Chrome extensions completely. The company has also been using machine learning technologies to detect and block malicious extensions. To take a step further, Google announced Monday five major changes that give users more control over certain permissions, enforces security measures, as well as makes the ecosystem more t
