The Power of a 5-Minute Phone Switch Off Against Hacking

The possibility of hacking is greater than ever in our increasingly digital society, where technology permeates every aspect of our lives. People and businesses are growing more vulnerable to cyberattacks as cybercriminals' techniques become more sophisticated. However, turning off your cell phone for just five minutes each day might be a quick but effective step in the fight against hacking.

Numerous experts have emphasized the importance of periodically disconnecting from the digital world to protect ourselves from potential security breaches. One of the main reasons for this recommendation is that mobile phones, even when not in use, can still be targeted by hackers. By switching off the device, individuals create a temporary shield that interrupts any potential hacking attempts.

According to cybersecurity professionals, a powered-off phone reduces the chances of unauthorized access to personal data and minimizes the risk of malware infiltration. It provides a brief respite from the constant online presence, allowing the phone to refresh and potentially thwart any ongoing hacking attempts.

Australian Prime Minister John Thompson recently advocated for this practice, urging residents to switch off their phones every night for a mere five minutes. He emphasized that this small act could have significant implications in enhancing cybersecurity and safeguarding personal information.

While switching off your phone may seem inconsequential, it interrupts the chain of connectivity and provides a momentary pause in the relentless stream of data transmission. This break can be crucial in identifying potential vulnerabilities and preventing hackers from gaining unauthorized access.

Furthermore, a brief daily power-down of your mobile device helps combat hacking and offers several additional benefits. It allows the phone's software to update and install the latest security patches, ensuring it remains protected against emerging threats. Regular updates are a crucial aspect of maintaining a solid defense against hackers.

Stress levels can be greatly reduced and mental health can be improved by taking a brief vacation from continual digital interaction. People may experience information overload and a sense of being always on due to the constant barrage of notifications, messages, and social media updates. People can feel relieved and reclaim a peaceful moment by unplugging even for a brief period.

Microsoft Conduct an Emergency Fix for the Notorious ‘Acropalypse’ Bug


Recently, Microsoft has acted quickly in patching up the ‘acropalypse’ bug that was discovered earlier this week. The bug could apparently enable information cropped out of images via the Windows screenshot tools to be recovered. 

According to BleepingComputer, Microsoft has now issued an OOB (out-of-band or emergency) update that patches the aforementioned issue, technically named CVE-2023-28303. Microsoft is now urging users to apply the update as soon as possible. 

Furthermore, the update is not difficult to apply. All that the user has to do is click the Library icon in Microsoft Store, then pick Get updates (top right). Doing so will enable the patch to be applied if it has not already been installed automatically. 

Carry on Cropping 

The acropalypse bug shares some similarities with the vulnerability that targeted the Markup feature on Google Pixel phones, i.e. images and screenshots cropped in the Windows 11 Snipping Tool and the Windows 10 Snip and Sketch tool could well be compromised. 

The CVE-2023-28303 bug signifies that parts of a PNG or JPEG image that has been cropped out are not completely removed from the file after it is saved again. These cropped sections could include a variety of sensitive information, like bank account credentials or medical records. 

Moreover, it is important to note that applying the patch would not be able to fix any file that has already been cropped and exploited. It will only be applied to the ones that will be edited in the future. Users must re-crop any existing images to ensure that the excess parts of the picture have been appropriately removed. 

Analysis: A Quick Fix for a Worrying Bug 

Initially, recovering cropped out part of images may not appear to be a significantly severe security vulnerability- after all, who would care if someone manages to recover some empty sky that you have removed from that one photo from one of your vacations? 

However, there are a lot of reasons that makes cropping is a serious problem, as tech journalists know all too well. One could compromise their personal and important information from these cropped images, like email address, bank account numbers and contact details. Thus, it is well advised to users to cut off any information as such information before sharing it widely over the internet. 

In today’s era, where one shares so many photos with others and on the web at large, it is important from a security perspective that these images do not, in any way, expose more than we want them to, something that was a case of concern with CVE-2023-28303. 

Although, Microsoft has acted quickly to patch the issue, it is still concerning to note that the same bug was being exposed to two completely separated software from both Microsoft and Google in recent days.  

Ransomware Targeting VMware ESXi Servers Rises

The Cybersecurity and Infrastructure Security Agency (CISA) and the FBI have released a joint advisory warning about an ongoing ESXiArgs ransomware campaign targeting unpatched and out-of-service or out-of-date versions of the VMware ESXi hypervisor for virtual machines (VMs).

The OpenSLP service contains a heap overflow bug that can be exploited by unverified threat actors in simple attacks. This security hole is identified as CVE-2021-21974 on the CVE database. 3,800 VMware ESXi servers around the world have reportedly been compromised, potentially rendering any running VMs useless, as per CISA.

Application of the patch as soon as feasible is strongly advised by CERT-FR, but it also says that systems that are not patched should be checked for indicators of compromise.

Although it has since moved to North America, the ESXiArgs ransomware appears to have begun attacking servers in Europe around February 3. Organizations should isolate impacted servers, reinstall ESXi 7. x or ESXi 8. x in a supported version, and apply any patches, according to the French computer emergency response team (CERT).

Updated ESXiArgs Ransomware

On infected ESXi hosts, the ransomware encrypts files with the. vmxf,.vmx,.vmdk,.vmsd, and. nvram extensions and produces a.args file for each encrypted document with metadata.

The research shows that ESXiArgs is based largely on stolen Babuk source code, which has previously been used by other ESXi ransomware attacks, including CheersCrypt and the PrideLocker encryptor from the Quantum/Dagon group. It is unclear whether this is a new variety or simply a shared Babuk codebase because the ransom notes for ESXiArgs and Cheerscrypt are quite similar but the encryption technique is distinct.

CISA and FBI urged owners of VMware ESXi servers to upgrade them to the most recent version, harden ESXi hypervisors by turning off the SLP service and make sure the ESXi hypervisor is not accessible through the open internet.

Microsoft Announced the End of Support for Windows 7 & 8

Microsoft has published a warning over the imminent end of support for Windows 8.1, which would not receive any updates or patches after January 10th, 2023.

According to the research, over 100 million computers were still running Windows 7 as of 2021, giving their owners little time to update them before they face the security hazards associated with utilizing an antiquated browser and operating system.

Windows 8.1 is still the fourth most popular Microsoft operating system in the world, according to the Statcounter team, with 2.45% of all Windows users having it installed on their computers. Given the fact that it will affect millions of individuals and expose numerous PCs to attack, this end of support is quite concerning. 

PCs running Windows XP, 7, or 8 were more prevalent than those running Windows 11 according to a Lansweeper survey of 27 million Windows devices conducted in October.

For systems running Windows 10 2004 or 20H2, Windows 10 21H1 was a minor feature update that was designed to be simple to install. It contained improvements to Windows Defender Application Guard, Windows Management Instrumentation via Group Policy, and support for several Windows Hello-enabled cameras. 

Along with the release of a new Chrome version, Google also disclosed that it will discontinue support for Windows 7 and Windows 8.1 in early 2023. For users to continue receiving new Chrome updates, their device must be running Windows 10 or later.

It would be wise for anyone running an outdated version of Windows to inspect their computers and make some critical adjustments this week. Microsoft has issued the warning because Windows 8.1 will soon stop receiving security updates and patches after January 10, 2023.
