Failed carriers

Years pass, but the dissatisfaction of users with the quality of services of telecommunication networks always remains strong. Despite a slight improvement compared to 2020, Arcep notes that 41% of the warnings relate to the quality of service and after-sales service offered by operators to their subscribers.

Most of the warnings concern the quality of the fixed connection. But SFR fiber is also concerned, as its XpFibre subsidiary is currently the subject of an administrative investigation by a telecommunications police officer. Finally, communication remains at the center of criticism.

Microsoft is reviewing its licensing policy in Europe

In response to several complaints, Microsoft laid out five “European Cloud Principles” and planned changes, including uniform rules for European cloud providers when it comes to using Microsoft software on their own infrastructure.

Recall that the American giant has been the target of several complaints from European cloud service providers regarding its restrictive licensing policy: consumers had to pay more to run Microsoft software in cloud environments other than Microsoft Azure.

Ransom note printed at home

During a ransomware attack, the US administration received a ransom note… in its printer. Indeed, the note was sent to a network printer and printed out on paper with an email address and contact details.

This attack, which took place in March 2022, was attributed to Cobalt Mirage, an Iranian hacker group also known as APT35, Charming Kitten, Phosphorus, and TA453. Cyber ​​attackers used ProxyShell vulnerabilities to remotely access vulnerable systems, including stealing data.

Key figure: 2-3 days of remote work

According to the National Council for Productivity, which assessed France’s performance during the health crisis in a report, teleworking can have a long-term positive impact on business productivity.

In 2019, 4% of employees regularly worked remotely, up from 27% in January 2021. And 80% of them want to continue working remotely. However, 100% remote work is not recommended as it can weaken communication and reduce social interaction. Ideally, according to the council, there would be two to three days of remote work per week.

Practicality: 5 tips for protecting your hearing

With remote work and distance learning, we spend more and more time wearing headphones. Here are five tips for protecting your ears:

  • arm yourself with the right equipment (and avoid headphones);
  • use ANC headphones (and don’t turn up the volume);
  • choose equipment with clear, high-quality sound;
  • take breaks;
  • use tools to limit the volume.

Editorial Spotlight: SIM Replacement

“SIM Swapping” or “SIM Swapping” in French is a very effective type of attack. With this technique, the attackers were able to hack into anonymous people and empty their bank accounts, as well as connect to the founder’s Twitter account to post racist messages.

The essence of replacing a SIM card is to restore the SIM card assigned to the subscriber by the operator. And for this, all means are good. It is difficult for the victim to cope with this type of hacking. The only way to solve the problem is to contact your carrier, report the attack and ask them to block the new SIM card obtained by the pirates. Unfortunately, this may take some time.
