Sicherheitsforscher gelingt Einbruch in interne Systeme von Apple, Tesla, Microsoft und Co.

Dem Sicherheitsforscher Alex Birsan ist es in den USA gelungen, mit vergleichsweise simplen Mitteln in die internen Systeme von mehr als 35 großen Unternehmen, darunter Apple, Tesla, Microsoft und PayPal einzudringen (via Bleeping Computer). Dabei nutzte er eine einzelne Sicherheitslücke in einem Zusammenspiel verschiedener Open-Source-Anwendungen namens "Dependency Confusion" aus. Hierbei hat Birsan eine Malware in Open-Source-Repositories wie PyPI, npm oder RubyGems eingeschleust, die sich dann in die internen Systeme der Unternehmen weiterverbreiteten. Das Perfide dabei: Auf den betroffenen werden die aktualisierten Pakete austomatisch per Update installiert, ohne dass der nutzer hiervon etwas mitbekommt, Trojaner eingeschleust werden müssen oder Social Engineering angewandt werden muss.

Dabei machte sich der Sicherheitsforscher das Aktualisierungskonzept mancher Open-Source-Repositories zunutze. Beispielsweise ist es beim Paket PyPI so, das grundsätzlich jedes Paket mit einer neueren als der aktuell installierten Versionsnummer heruntergladen wird, unabhängig davon, wo es im Internet angeboten wird. Eine durchaus bemerkenswerte Gefahr, die auch für viele andere Nutzer ein Problem darstellen kann. Nach dem erfolgreichen Angriff auf die Systeme informierte der Sicherheitsforscher die betroffenen Unternehmen und wies sie auf das Problem hin. Teilweise erhielt er hierfür sogar Belohnungen, wie etwa 40.000,- US-Dollar von Microsoft oder einen nicht näher bezifferten Betrag aus Apples Security Bounty Program. Insgesamt soll birsan auf diese Weise  mehr als 130.000,- Dollar verdient haben. Zurecht, wenn man mich fragt.

Wer sich für die Details der ausgenutzten Sicherheitslücke interessiert, findet diese auf Alex Birsans Medium Page.

Is it smart to use a general one-size-fits-all resume, which you can submit anytime, anywhere, for any job offering? Answer: It is a stupid idea! The truth: Employers have to sort through up to five hundred resumes per day! So they throw away every resume which is not intentionally targeted to the position being offered.

Most employers view the duties/responsibilities resume technique, as obsolete and of no value. Instead, organizations want to discover what places you above the other rivals, with actual instances of achievements you have made for prior engagements.

Today's organizations consider the duties/responsibilities resume approach, as outdated and valueless. Instead, companies wish to see what places you above the other candidates, plus tangible examples of achievements you've made for past employers.

Most job searchers don't know that four of every five job offerings (including just about every one of the highest-paying jobs), are only hired within the "hidden" employment market. This means the secret to rocketing your pay level, is to find out the most common reasons the best-paying occupations are promoted via this rarely discussed employment market, but rarely the tiny print newspaper or internet employment market.

If you're hunting for a job, first impressions are very important! And the very first impression organizations read about you - is a professional cover letter.

The lion's share of companies consider the duties and responsibilities resume format, as outdated and worthless. Instead, organizations want to see what sets you apart from other candidates, plus on-the-job examples of achievements you have made at prior occupations.

professional resume writer newfoundland am :

Sticking to the Duties-and-Responsibilities resume template, will guarantee that your resume lines a garbage can! Companies couldn't care less about what you were responsible for at prior occupations. Rather, they want to see what real achievements you have made.

If you're searching for hired, first impressions are top priority! And the most frequent first impression organizations have of you - is a professional cover letter.

Aber Open-Source ist ja immer die Lösung für alles. Behaupten die Anhänger.

Böser goldener Apple-Käfig.
Ja, von wegen. Da arbeiten auch nur Menschen. Die ihre Pakete offenbar nicht mal signieren. Das sind Fachleuchten....

Da fällt mir ein: Unsere Nachfrage, ob es unter Linux Datenschutzeinstellungen wie bei Apple gibt, wurde mit Verweis auf Open-Source-Source als nicht relevant abgetan.

A surprising fact is that 80 of jobs (and specifically pretty-well 100 of the highest-paying positions), are only hired within the "hidden" career market. So the power pathway to improving your job results, is to find out the most frequent reasons the best employment are advertised inside this little-known career market, but rarely the tiny "mainstream" media or cyberspace job market.

Most job searchers don't know that four of every five job postings (including just about every one of the top work), are only posted inside the "hidden" job market. So the power pathway to improving your job results, is to find out the leading reasons the highest-paying employment are available only via this rarely discussed career market, and not the pathetic public or online career market.

You need to guarantee that a professional cover letter peaks the interest of your prospective hiring decision-maker, builds their confidence in you, plus entices them to review your resume so they decide to choose you for the interview. Because of the overwhelming volume of resumes received for every work offer currently, the cover letter frequently becomes the key selection factor between whether you score an interview - or get dropped into the garbage!

professional resume writers north york am :

In earlier times, all resumes began by writing an Objective Statement - but no longer! Smart employment experts all agree, this category of resume sections fail when determining your employment suitability. Thus, be certain to not use an Objective Statement!
