Milliarden Geräte betroffen: Sicherheitslücke in WLAN-Chips verlangt dringende Updates

Geschrieben von Florian Schimanke am

Allen Update-Muffeln da draußen, die noch mit einer älteren iOS/iPadOS-Version als 13.2 bzw. macOS 10.15.1 unterwegs sind, sei ein baldiger Gang in die Einstellungen ihrer iPhones, iPads und Macs empfohlen, um ihr Gerät zu aktualisieren. Auf der RSA Security Conference wurde aktuell nämlich eine schwere Sicherheitslücke in verschiedenen WiFi-Chips von Cypress Semiconductor und Broadcom vorgestellt, die auch in den Apple-Geräten verbaut sind (via Ars Technica). Die auf den Namen "Kr00k" getaufte Lücke erlaubt es theoretisch einem Angreifer, kabellose übertragene Daten abzufangen und zu entschlüsseln. Grund hierfür ist eine fehlerhafte Implementierung der Verschlüsselung. Apple hatte diese Lücke bereits im vergangenen Oktober mit der Veröffentlichung von iOS 13.2 und macOS 10.15.1 behoben.

Auch andere Hersteller und Geräte, in denen Chips der beiden Hersteller zum Einsatz kommen, sind von dem Problem betroffen. Namentlich genannt wurden dabei unter anderem Amazon (Echo, Kindle), Google (Nexus), Samsung (Galaxy), Raspberry (Pi 3), Xiaomi (RedMi), sowie einzelne Access Points von Asus und Huawei. Auch hier haben die meisten Hersteller bereits entsprechende Patches ausgeliefert. Die Sicherheitsexperten von ESET Research raten allen Verbrauchern dazu, ihre Geräte auf möglicherweise vorhandene Updates zu überprüfen und diese auch zeitnah zu laden und zu installieren.

Wurde der Fehler auch in Mojave behoben?

I wish other writers of this category of reading material would spend the time you have done, to investigate the subject so expertly. I'm highly impressed!

Today's organizations rate the duties and responsibilities resume template, as snooze-worthy and of no value. Instead, hiring decision-makers wish to read what sets you apart from other resumes, plus tangible examples of accomplishments you made at former occupations.

resume writing service calgary am :

In today's job market, organizations won't pay attention to all of the four hundred or greater resumes they get - for just one employment opening! The fact is, they will quickly discard ninety percent of them, if any resume does nothing to capture their interest.

resume writing service fredericton am :

Most people fail to realize that four of every five job offerings (and particularly almost 100 of the highest-paying employment), are only hired within the "hidden" employment market. Thus the key to rocketing your career, is to find out the leading reasons the highest-paying occupations are exclusively via this little-known career market, but rarely the miniscule paper media or cyberspace employment market.

resume writing north bay am :

Resume statements as for example "highly skilled", mean nothing. They sound cliche and don't put you in a positive light. This is also true for a statement such as "hard worker". The correct text focus on what you accomplished for your prior employers and how valuable you could be to this prospective company.

resumes ontario am :

Way back in the past, job hunters were lectured that our resume needs to include a group of point-form duties and responsibilities underneath each work position we have ever had - and the higher the number the better. Not anymore! Currently, companies plan to only take a few seconds (possibly much less) when reviewing your resume. Do not choose the duties/responsibilities resume template!

executive resume writing new brunswick am :

Resume text as for example "highly skilled", mean nothing. They make you sound cliche and fail to position you in a positive way. Similarly for a phrase like "reliable". The correct terms point out things you accomplished while at your former employment and in addition how beneficial you can be to this potential employer.

Is it smart to write a general one-size-fits-all resume, that you can submit anytime, anywhere, for any work? What Hiring Professionals say: It is a dumb choice! The truth: Organizations must deal with up to four hundred resumes each day! As a result, they throw out every resume that is not intentionally targeted to the job being offered.

resume writers thunder bay am :

Long ago, resumes started by writing an Objective Statement - but not now! In today's job market, employment professionals all confirm, these kinds of resume items do nothing when determining your employment capability. Thus, never write an Objective Statement!

resume writer moncton am :

Nowadays, hiring decision-makers want to be told the unique employment title you want to apply for - but a general resume fails to include this. On top of that, they immediately want to learn what positively differentiates you - but a general resume makes you look just like the other 499 general resumes they have already seen submitted.

professional resume moncton am :

In today's job market, companies will not pay attention to each of the 400 or greater resumes they get - for each employment offering! Instead, they'll happily throw away ninety-five percent of them, if that resume does nothing to grab the reader's interest.

resume writers peterborough am :

You need to ensure that your cover letter hooks your prospective employer, presents you in the most positive light, and also convinces them to read your resume so they can choose you for the interview. Given the excessive volume of resumes sent to every job offer currently, the cover letter typically becomes the leading selection factor as to whether you score an interview - or get dropped into the garbage!

Can I firmly say what a relief it is to discover a person who clearly is aware of what they're talking about - that is so rare to see on the internet!

You have written about a bunch of strong points here. Let's hope that lots of people get this post.

professional resume writing manitoba am :

These days, hiring decision-makers must have the actual position title you want to apply for - while a general resume never has this. In addition, they immediately need to learn what positively makes you a better choice - and a general resume forces you to appear the same as the other 499 general resumes they've already had sent to them.

resume writing services york region am :

It used to be, the standard resume opened with an Objective Statement - but no longer! In today's job market, employment experts all state clearly, this category of statements do nothing when determining your employment skills. Thus, never include an Objective Statement!

resume writer windsor am :

Long time ago, job searchers were taught that every resume needs to include a list of bullet-point duties and responsibilities required by every occupation we've ever done - and the more the better. Not anymore! Currently, companies plan to only take 10 seconds (maybe even less) when glancing through your resume. Do not choose the duties/responsibilities resume template!

resumes newfoundland labrador am :

Many years ago, we were told that every resume needs to have a group of bullet-point duties and responsibilities performed during every work position we've ever occupied - and the more the better. Not now! Today, employers are able to only devote a dozen seconds (possibly much less) when reviewing your resume. Do not follow the duties/responsibilities resume approach!

resumes am :

Should you use a general one-size-fits-all resume, that you can use anytime, anywhere, for any work? The Truth: It is a foolish blunder! The key fact: Organizations have to read through as much as five hundred resumes each day! Thus they toss out every resume that is not narrowly targeted to the work being offered.

executive resume belleville am :

Years and years ago, we were lectured that every resume must include a collection of bullet-point duties and responsibilities required by each employment we have ever occupied - and the bigger the list the better. No longer! Nowdays, organizations will only spend a few seconds (maybe even less) when skimming through your resume. Don't follow the duties/responsibilities resume template!

resume writers cambridge am :

Today's employers don't look at all of the five hundred plus resumes submitted - for every job opening! Instead, they'll immediately discard 90 of them, if that resume does nothing to grab the reader's attention.

resume writing services british columbia am :

You will want to confirm that the cover letter hooks your future company, reassures them, and then convinces them to look at your resume so they will choose you for an interview. Given the huge volume of resumes submitted to every job offer in today's market, an expertly-written cover letter often becomes the leading distinguishing factor choosing if you are awarded an interview - or get dropped into the garbage!

resume writers sydney nova scotia am :

The lion's share of employers rate the duties and responsibilities resume technique, as boring and worthless. Instead, hiring decision-makers want to read what distinguishes you from other competitors, plus real-life instances of improvements you made at previous employers.

executive resume writing durham region am :

If you're trying to get employed, first impressions are top priority! And the most frequent first impression organizations know of you - is your cover letter.

Your web site was recently enthusiastically reviewed by a neighbor. Thus I finally figured that I should come by and take a peek. Good move!
