2023-11-28 11:00:00 | Pour le manque de cyber ongle, le royaume est tombé For want of a cyber nail the kingdom fell (lien direct) |
An old proverb, dating to at least the 1360’s, states: "For want of a nail, the shoe was lost, for want of a shoe, the horse was lost, for want of a horse, the rider was lost, for want of a rider, the battle was lost, for want of a battle, the kingdom was lost, and all for the want of a horseshoe nail," When published in Ben Franklin’s Poor Richard’s Almanack in 1768, it was preceded by the cautionary words: “a little neglect may breed great mischief”. This simple proverb and added comment serve as emblematic examples of how seemingly inconsequential missteps or neglect can lead to sweeping, irreversible, catastrophic losses. The cascade of events resonates strongly within the increasingly complex domain of cybersecurity, in which the omission of even the most elementary precaution can result in a spiraling series of calamities. Indeed, the realm of cybersecurity is replete with elements that bear striking resemblance to the nail, shoe, horse, and rider in this proverb. Consider, for example, the ubiquitous and elementary software patch that may be considered the proverbial digital "nail." In isolation, this patch might seem trivial, but its role becomes crucial when viewed within the broader network of security measures. The 2017 WannaCry ransomware attack demonstrates the significance of such patches; an unpatched vulnerability in Microsoft Windows allowed the malware to infiltrate hundreds of thousands of computers across the globe. It wasn\'t just a single machine that was compromised due to this overlooked \'nail,\' but entire networks, echoing how a lost shoe leads to a lost horse in the proverb. This analogy further extends to the human elements of cybersecurity. Personnel tasked with maintaining an organization\'s cyber hygiene play the role of the "rider" in our metaphorical tale. However, the rider is only as effective as the horse they ride; likewise, even the most skilled IT professional cannot secure a network if the basic building blocks—the patches, firewalls, and antivirus software—resemble missing nails and shoes. Numerous reports and studies have indicated that human error constitutes one of the most common causes of data breaches, often acting as the \'rider\' who loses the \'battle\'. Once the \'battle\' of securing a particular network or system is lost, the ramifications can extend much further, jeopardizing the broader \'kingdom\' of an entire organization or, in more extreme cases, critical national infrastructure. One glaring example that serves as a cautionary tale is the Equifax data breach of 2017, wherein a failure to address a known vulnerability resulted in the personal data of 147 million Americans being compromised. Much like how the absence of a single rider can tip the scales of an entire battle, this singular oversight led to repercussions that went far beyond just the digital boundaries of Equifax, affecting millions of individuals and shaking trust in the security of financial systems. | Ransomware Data Breach Malware Vulnerability | Wannacry Wannacry Equifax Equifax | ★★ |

The content of this post is solely the responsibility of the author. AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article. With the changing security landscape, the most daunting task for the CISO and CIO is to fight an ongoing battle against hackers and cybercriminals. Bad actors stay ahead of the defenders and are always looking to find new vulnerabilities and loopholes to exploit and enter the business network. Failing to address these threats promptly can have catastrophic consequences for the organization. A survey finds that, on average, it takes more than five months to detect and remediate cyber threats. This is a significant amount of time, as a delayed response to cyber threats can result in a possible cyber-attack. One can never forget the devastating impacts of the Equifax breach in 2017 and the Target breach in 2013 due to delayed detection and response. This is concerning and highlights the need for proactive cybersecurity measures to detect and mitigate rising cyber threats. Amidst this, it\'s also crucial to look into why it is challenging to detect cyber threats. Why do organizations fail to detect cyber threats? Security teams are dealing with more cyber threats than before. A report also confirmed that global cyber attacks increased by 38% in 2022 compared to the previous year. The increasing number and complexity of cyber-attacks make it challenging for organizations to detect them. Hackers use sophisticated techniques to bypass security systems and solutions - like zero-day vulnerabilities, phishing attacks, business email compromises (BEC), supply chain attacks, and Internet of Things (IoT) attacks. Some organizations are unaware of the latest cyber threat trends and lack the skills and resources to detect them. For instance, hackers offer professional services like ransomware-as-a-service (RaaS) to launch ransomware attacks. Surprisingly, two out of three ransomware attacks are facilitated by the RaaS setup, but still, companies fail to have a defensive strategy against them. Enterprises relying on legacy devices and outdated software programs are no longer effective at recognizing certain malicious activities, leaving the network vulnerable to potential threats. Additionally, the lack of trained staff, insider threats, and human errors are other reasons why many organizations suffer at the hands of threat actors. Besides this, much of the company\'s data is hidden as dark data. As the defensive teams and employees may be unaware of it, the hackers take complete advantage of dark data and either replicate it or use it to fulfill their malicious intentions. Moreover, cloud migration has rapidly increased in recent years, putting cybersecurity at significant risk. The complexity of the cloud environments, poorly secured remote and hybrid work environments, and sharing security responsibilities between cloud service providers and clients have complicated the situation. In addition, cloud vulnerabilities, which have risen to 194% from the previous year, have highlighted the need for organizations to look out for ways to strengthen their security infrastructure.

2023-02-14 12:06:06 | What Will It Take? (lien direct) | What will it take for policy makers to take cybersecurity seriously? Not minimal-change seriously. Not here-and-there seriously. But really seriously. What will it take for policy makers to take cybersecurity seriously enough to enact substantive legislative changes that would address the problems? It's not enough for the average person to be afraid of cyberattacks. They need to know that there are engineering fixes—and that's something we can provide. For decades, I have been waiting for the “big enough” incident that would finally do it. In 2015, Chinese military hackers hacked the Office of Personal Management and made off with the highly personal information of about 22 million Americans who had security clearances. In 2016, the Mirai botnet leveraged millions of Internet-of-Things devices with default admin passwords to launch a denial-of-service attack that disabled major Internet platforms and services in both North America and Europe. In 2017, hackers—years later we learned that it was the Chinese military—hacked the credit bureau Equifax and stole the personal information of 147 million Americans. In recent years, ransomware attacks have knocked hospitals offline, and many articles have been written about Russia inside the U.S. power grid. And last year, the Russian SVR hacked thousands of sensitive networks inside civilian critical infrastructure worldwide in what we're now calling Sunburst (and used to call SolarWinds)... | Ransomware | Equifax Equifax Solardwinds | ★★ |

Cybersecurity may be different based on a person's viewpoint. One may want to simply protect and secure their social media accounts from hackers, and that would be the definition of what cybersecurity is to them. On the other hand, a small business owner may want to protect and secure credit card information gathered from their point-of-sale registers and that is what they define as cybersecurity.
Despite differences in implementation, at its core, cybersecurity pertains to the mitigation of potential intrusion of unauthorized persons into your system(s). It should encompass all aspects of one’s digital experience--whether you are an individual user or a company.
Your cyber protection needs to cover your online platforms, devices, servers, and even your cloud storage. Any unprotected area of your digital journey can serve as an exploit point for hackers and cyber criminals intent on finding vulnerabilities.
People assume that it is the responsibility of the IT Department to stop any intrusion. That may be true up to a certain point, cybersecurity responsibility rests with everyone, in reality.
Cybersecurity should be everybody’s business.
The cybersecurity landscape is changing. With 68% of businesses saying that their cybersecurity risks have increased, it is no wonder that businesses have been making increased efforts to protect from, and mitigate attacks.
During the height of the pandemic, about 46% of the workforce shifted to working from home. We saw a surge in cybersecurity attacks - for example, RDP brute-force attacks increased by 400% around the same time.
This is why cybersecurity must be and should be everybody’s business. According to the 2019 Cost of Cybercrime Study, cyberattacks often are successful due to employees willingly participating as an internal actors or or employees and affiliates carelessly clicking a link by accident.
Sadly, it is still happening today. Unsuspecting employees can be caught vulnerable and cause a corporate-wide cyberattack by opening a phishing email or bringing risks into the company’s network in a BYOD (Bring Your Own Device) system.
Just a decade ago, Yahoo experienced a series of major data breaches, via a backdoor to their network system established by a hacker (or a group of hackers). Further digital forensic investigation shows the breach started from a phishing email opened by an employee.
Another example was Equifax when it experienced a data breach in 2017 and was liable for fines amounting to $425 million by the Federal Trade Commission (FTC).
Companies continue to double up on their investments in cybersecurity and privacy protection today to ensure that incidents like these do not happen to their own networks. But a network is only as strong as its weakest link. Hackers continue to innovate, making their attacks more and mo |

Recent statistics show that 60% of businesses are forced to suspend operations after a cyber-attack are never able to reopen for business. This is largely due to revenue lost due to downtime as well as damage to the company’s reputation. The good news is that most of these threats can be mitigated with reliable cybersecurity. When it comes to cyberattacks, time is of the essence. Businesses should install systems that will enable them to detect potential threats so as to respond in a timely manner. One of the recommended solutions is a combination of services and products from AT&T Cybersecurity, which provides edge-to-edge protection to enable businesses stay ahead of threats.
Data Breach Prevention
Data breaches happen when cyber criminals successfully attack systems that hold sensitive information. In the case of businesses, this may include crucial information such as employee and customer records. The exfiltration of such data outside organizational boundaries can lead to costly fines and massive monetary losses. This is evident by the fining of Equifax after it experienced a breach that exposed data belonging to 146 million people. However, businesses can employ standard security software such as antivirus and intrusion detection systems to defend against data leakages by monitoring sensitive files and data transfers.
Phishing prevention
Phishing involves the use of digital messages by cyber criminals to steal credit card information, user logins and other types of sensitive data. Cases of phishing attacks have been on the rise and any business on the web can be targeted. As more businesses are aware of the risks posed by suspicious emails and links, hackers have upped the ante by using machine learning to distribute malicious messages with the aim of targeting frail businesses.
Sensitive data can also be compromised by third parties, such as partners and contractors. Businesses should employ effective strategies for finding partners and contractors so as to reduce security risks posed by them. Employee training, installation of security systems and updating of all software are essential methods to greatly reduce phishing attacks.

Ransomware prevention & detection
For many businesses around the world, ransomware can be a nightmare. The average ransomware attack costs a company a whopping $133,000. Cyber criminals make use of malicious software to encrypt a victim’s data and then demand ransoms in order to decrypt the data. Paying these ransoms doesn’t always guarantee access, since criminals cannot be trusted and so businesses should take measures to avoid such situations. One of the measures is to use updated security software, have a good backup and restore plan and also to train employees on how to avoid emails that may carry ransomware.
The importance of cybersecurity cannot be stressed enough. Companies have been reduced to rubble because of inadequate security to their systems. Cyber criminals are |
