A messaging app released by the French government to secure internal communications has gotten off to a troubled start.
Tchap was released in beta earlier this month as a secure messaging app exclusively for government officials. Its development and release was made to address security concerns and data vulnerabilities in more widely used apps including WhatsApp and Telegram (a favorite of French Prime Minister Emmanuel Macron).
WhatsApp Meet “What Were You Thinking?”
Tchap was built with security in mind, and was initially touted as being “more secure than Telegram.” Man plans and God laughs. The app was hacked within less than a day of its release. Elliot Alderson, the hacker who discovered the initial security vulnerability, subsequently found four more major flaws in its code, and confirmed with the app’s developer that no security audit was performed on the app prior to release.
DINSIC, the government agency responsible for Tchap, issued a press release stating that the software “will be subject to continuous improvement, both in terms of usability and security,” and has since announced a bug bounty for further vulnerabilities.
The French government’s attempts at creating a secure messaging alternative highlights a cybersecurity conundrum. Recent incidents including the allegations of Chinese government “backdoors” in telecom giant Huawei’s hardware and confirmed NSA backdoors in Windows software have left governments and businesses increasingly wary of using software or hardware developed or data stored internationally. At the same time, development of in-house or “proprietary” solutions are significantly more resource-intensive and not necessarily more secure than their more widely used counterparts.

These are the places your digital tracks can be dug up. With a little sleuthing.
Experts have warned for years of the risks of using public computers such as those found in libraries, hotels, and airline lounges.
Many warnings focused on the potential for hackers to plant keystroke loggers, or intercept data as it flows across the internet. Indeed, in 2014, the National Cybersecurity and Communications Integration Center of the U.S. Secret Service issued an advisory for “owners, managers, and stakeholders in the hospitality industry” concerning data breaches. The text of the advisory claimed, “The attacks were not sophisticated, requiring little technical skill, and did not involve the exploit of vulnerabilities in browsers, operating systems or other software.” A 2014 announcement may seem to be an outdated reference, except that the recent Marriott data breach of over 300 million records was attributed to an attack in…wait for it…2014.)
But spyware and keyloggers aren’t the most common threat to the users of business center and other public computers. Forgetfulness, operating systems, applications, and temporary files are high up on the list. For several years I have searched public computers, mostly at hotels, to see what kinds of information people have left behind. It’s been an interesting passion project, to say the least.
Uncovering a Very Public Digital Paper Trail
The first places I look are the documents, downloads, desktop, and pictures folders. The pictures folder typically yields the least interesting information, usually pictures of groups of drunken people, group gatherings at restaurants, weddings, or cats.
The desktop, document, and occasionally downloads folders are where most documents are inadvertently left behind. Some interesting samples I’ve discovered include a spreadsheet of faculty merit raises at a university in Texas, including the names of professors, their departments, their current salaries, and their projected raises. Another was the assignment of a chief officer to a ship belonging to one of the largest shipping companies in the world. It included the officer’s name, address, phone number, vessel name, date of assignment, and contact information.
I have come across corporate audits and strategic business plans. Recently, I discovered a document called “closing arguments” created by a district attorney. When possible, I contact the owners of the information to help them understand the risks of using public computers for sensitive work. I rarely hear back, however the DA did thank and assure me the document was a training example.
The biggest menace, however, has been the temporary files folders, which include auto-saved documents and spreadsheets, as well as attachments. It is in the Temporary Internet Files folder that I have uncovered complete emails, and even a webpage including a bank statement detailing a large balance, the account holder’s name, sources of income, and the names and addresses of places he had done business. Of all of the temporary files I have discovered, documents belonging to businesses’ employees have been the most unsettling.
If you must, take precautions
There is some good news concerning the safety of public computers. Due to technology changes, I no longer find the contents of emails in the Temporary Internet Files folder. But we’re far from out of the woods. I have found my inbox cached, including pictures within emails and even a PDF that had not yet opened.
Deleting temporary internet files is a good habit, but there are multiple locations that temporary files are stored. Documents edited on public computers remain of particular concern. Due to auto-save features, it’s possible to open a document on a thumb drive and leave auto-saved documents behind on the computer. Now in normal operating circumstances and with current operating systems and Office applications, this is not likely to happen. But errors like OS and application crashes will leave these copies behind. Microsoft Word and Excel will even proactively offer these auto-saved documents to the next user of these applications
Other than finding and deleting information left behind, my use of public computers is limited to reading online articles, checking the weather, and performing internet searches. What personal information you are willing to leave behind on a public computer depends on your risk tolerance. But it’s important to note that accessing corporate data on public computers could result in an inadvertent violation of company policies involving confidential data.
Although I still find public computers running Windows XP, there is a growing shift in the hospitality industry to use Kiosk applications. These provide limited functionality combined with locked-down security configurations. Access to the start menu is not possible and functionality is limited to desktop applications. Printing of boarding passes is a common allowed application. Reading web email is sometimes allowed, though I don’t recommend it because it requires entering a password. The risk of password compromise may be low, but the value of practicing quality security habits leads me to advise against it. If you must, consider changing your email password the next time you log onto a private computer.
If you happen to be using a public computer without a Kiosk interface, would you be so kind as to copy this blog, paste it into a Word document, and save it on the public computer to help inform the next user? They may end up paying it forward.

While many of us were focused on the European Union’s GDPR and California’s Consumer Privacy Act (CCPA), the giant on the other side of the world implemented China’s Cybersecurity Law (CSL) in June 2017. While CSL laid out broad data protection principles, there were noticeable gaps related to implementation and overall scope. To operationalize and further clarify CSL scope, the Chinese government instituted six systems: the Internet Information Content Management System; the Cybersecurity Multi-Level Protection System (MLPS); the Critical Information Infrastructure Security Protection System; the Network Products and Services Management System; the Cybersecurity Incident Management System; and the Personal Information … Continue reading The Giant Awakens – China’s Cybersecurity Law (CSL) and Data Protection Obligations

Every organization wants to expedite processes, reduce costs, and bolster their staff. And in today’s modern digital world, these objectives are largely attainable, but can occasionally come with some unwarranted side effects. With all the devices an organization uses to achieve its business’ goals, things can occasionally get lost in the shuffle, and cybersecurity issues can emerge as a result. Balancing your business’ objectives while ensuring your organization’s data is secure can be a challenge for many. But that challenge can be assuaged by addressing cyberthreats at the start – the endpoint. Adopting an effective endpoint protection strategy is crucial for a modern-day organization and defines a strong security posture. In fact, the importance of endpoint security has even caught the eye of venture capitalist firms, who are investing billions a year in the cybersecurity sector. But what exactly are the components of a successful endpoint security strategy? Let’s break it down.
Ensure the Basics Are in Place
If there’s one thing my previous experience with consumer security has taught me, it’s that the proliferation of connected devices is showing no signs of slowing. The same goes for the connected devices leveraged by businesses day in and day out. Organizations often give multiple devices to their workers that will be used to communicate and contain crucial business-specific information. These devices are used by employees that go just about anywhere and do just about everything, so it’s important businesses equip their people with the tools they need to protect these devices and the data they safehouse.
The first important tool – VPNs, or Virtual Private Networks. The modern workforce is a mobile one, and professionals everywhere are carrying their devices with them as they travel and connect to public Wi-Fi networks. Public Wi-Fi networks are not typically the most secure, and VPNs can help ensure those mobile devices connect securely to avoid potentially exposing data.
These devices should always have strong authentication as well, which acts as the first line of defense for any security issues that arise. Remind everyone that their devices should be locked with a strong and complex password that acts as the gatekeeper for their device. That way, the company will be protected if that individual endpoint device becomes lost or stolen.
Empower Your Employees to Do Their Part
One of the most important tools to equip your employees with is proper security training. In order to keep endpoint devices safe and networks secure, employees should undergo regular security training sessions. This training should keep everyone up-to-date on the latest threats, the necessary precautions they need to take when browsing the web, and how their individual devices can impact an organization’s network.
One main point to hit upon during employee security training – the importance of updates. Updating your device software can feel like a menial task, but the gravitas behind the ask cannot be understated. Outdated software was the cause of the WannaCry global cyberattack and will be a differentiator moving forward for when attacks do come after individual endpoint devices.
Make Predictive Technology an Essential
Now, in order to anticipate major cyberattacks like WannaCry, adopting predictive technology for your endpoint security strategy is of the utmost importance, as these innovations can be used to guide your incident response strategy. Take it from hundreds of IT professionals, who in a recent SANS survey expressed that predictive technologies – such as machine learning (ML) and artificial intelligence (AI) – are required in order to go from already knowing bad elements to focusing on identification of abnormal behavior.
ML and AI technology are also particularly crucial for visibility. This technology can empower security teams to gain insight into their endpoint detection and response systems, which automatically reduces the time required to address threats. Therefore, businesses need to have this predictive technology in place to anticipate and quickly gain insight into all threats affecting their organization’s network.
Adopt Innovative Technology
For those unsure where to start when it comes to AI and ML, there’s good news – there are actually endpoint security solutions out there that have predictive technology included in their build. Solutions such as McAfee MVISION Mobile and McAfee MVISION Endpoint have machine learning algorithms and analysis built into their architecture to help identify malicious behavior and attack patterns affecting endpoint devices.
Innovative solutions such as these will act as the cherry on top of your endpoint security strategy. So, it is crucial to take the time to invest in the right technology, irrespective of the nature of your enterprise. By creating the right combination of process and product, your organization’s network will be secure, and you won’t have to pick between business growth and a healthy security posture.

The UK is one of the few countries that has seen a year-on-year reduction in ransomware attacks, a new study has found.
According to the 2019 SonicWall Cyber Threat Report, ransomware infections in the UK decreased by 59% in the past year, a stark contrast to the 11% increase globally.
Has the UK learned a lesson?
Several experts believe the UK’s astounding resilience to ransomware is a direct result of 2017’s WannaCry attack. The ransomware tore through organisations across the globe but struck most acutely in the UK – at the NHS in particular.
The attack did little to demonstrate the financial appeal of ransomware for crooks. The incident became so high profile that most organisations learned that it wasn’t worth paying the ransom, and those behind the attack struggled to recoup the money that was paid into their Bitcoin account.
Likewise, the attack didn’t provide an accurate reflection of how incidents normally play out. The malware is usually most successful when it stays under the radar and catches out organisations that lack backup protocols, thereby seemingly forcing them to comply with the blackmailer’s request.
However, WannaCry taught the UK two huge lessons – that ransomware is dangerous and that organisations need to plan for it.
Bill Conner, president and CEO of SonicWall, said that, following WannaCry, “you guys [the UK] were all over [ransomware].”
The attack prompted the UK government, along with the National Cyber Security Centre and UK-based businesses, to confront ransomware head on.
“Most of the vendors in the UK and their customers put solutions in place to protect against multiple family variants of ransomware,” said Conner.
There are two key steps to protecting your organisation from ransomware. First, you should regularly back up your important files. This enables you to delete infected files and restore them from backups.
The process will take a long time – often more than 24 hours – but the loss in productivity will almost certainly be less costly than paying a ransom. Plus, you need to factor in issues other than simply the cost of returning to business. There’s the possibility that crooks won’t keep their word once you’ve paid up. Equally, there’s the risk that complying with their demands has made yourself a target for future attacks.
It’s therefore always advisable to use backups where possible rather than paying a ransomware.
Of course, it’s even better if you don’t get infected at all, and the best way to do that is to boost staff awareness of ransomware. That brings us to the second key step to protecting your organisation.
Most ransomware (and malware generally) is delivered via phishing scams. Cyber criminals plant the malicious code in an attachment and trick employees into downloading it. If you can train your staff to spot a malicious email and report it, you can dramatically reduce the risk of becoming infected.
Get started with staff awareness
Our Phishing and Ransomware – Human patch e-learning course makes staff awareness training simple.
This ten-minute course introduces employees to the threat of phishing and ransomware, and describes the link between the two. Armed with this knowledge, your staff will be able to detect suspicious emails and know how to respond.
