Brian Krebs

Brian Krebs is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Brian Krebs rather than just read about it. In short: Brian Krebs (born 1972) is an American journalist and investigative reporter. He is best known for his coverage of profit-seeking cybercriminals.

Key takeaways

  • Brian Krebs belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Brian Krebs to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Brian Krebs from memory before moving on to harder problems.

Reference excerpt

Brian Krebs (born 1972) is an American journalist and investigative reporter. He is best known for his coverage of profit-seeking cybercriminals. Krebs is the author of a daily blog, KrebsOnSecurity.com, covering computer security and cybercrime. From 1995 to 2009, Krebs was a reporter for The Washington Post and covered tech policy, privacy and computer security as well as authoring the Security Fix blog.

Early life and education Born in 1972 in Alabama, Krebs earned a B.A. in International Relations from George Mason University in 1994. His interest in cybercriminals grew after a computer worm locked him out of his own computer in 2001.

Career

1999–2007 Krebs started his career at The Washington Post in the circulation department. From there, he obtained a job as a copy aide in the Post newsroom, where he split his time between sorting mail and taking dictation from reporters in the field. Krebs also worked as an editorial aide for the editorial department and the financial desk. In 1999, Krebs went to work as a staff writer for Newsbytes.com, a technology newswire owned by The Washington Post. When the Post sold Newsbytes in 2002, Krebs transitioned to Washingtonpost.com in Arlington, Virginia as a full-time staff writer. Krebs's stories appeared in both the print edition of the paper and Washingtonpost.com. In 2005, Krebs launched the Security Fix blog, a daily blog centered around computer security, cyber crime and tech policy. In December 2009, Krebs left Washingtonpost.com and launched KrebsOnSecurity.com. Krebs has focused his reporting at his blog on the fallout from the activities of several organized cybercrime groups operating out of eastern Europe that have stolen tens of millions of dollars from small to mid-sized businesses through online banking fraud. Krebs has written more than 75 stories about small businesses and other organizations that were victims of online banking fraud, an increasingly costly and common form of cybercrime.

2008–2012 Krebs wrote a series of investigative stories that culminated in the disconnection or dissolution of several Internet service providers that experts said catered primarily to cyber criminals. In August 2008, a series of articles he wrote for The Washington Post's Security Fix blog led to the unplugging of a northern California based hosting provider known as Intercage or Atrivo. During that same time, Krebs published a two-part investigation on illicit activity at domain name registrar EstDomains, one of Atrivo's biggest customers, showing that the company's president, Vladimir Tšaštšin, recently had been convicted of credit card fraud, document forgery and money laundering. Two months later, the Internet Corporation for Assigned Names and Numbers (ICANN), the entity charged with overseeing the domain registration industry, revoked EstDomains' charter, noting that Tšaštšin's convictions violated an ICANN policy that prohibits officers of a registrar from having a criminal record. In November 2011, Tšaštšin and five other men would be arrested by Estonian authorities and charged with running a massive click fraud operation with the help of the DNS Changer Trojan. In November 2008, Krebs published an investigative series that led to the disconnection of McColo, another northern California hosting firm that experts said was home to control networks for most of the world's largest botnets. As a result of Krebs's reporting, both of McColo's upstream Internet providers disconnected McColo from the rest of the Internet, causing an immediate and sustained drop in the volume of junk e-mail sent worldwide. Estimates of the amount and duration of the decline in spam due to the McColo takedown vary, from 40 percent to 70 percent, and from a few weeks to several months. Krebs is credited with being the first journalist, in 2010, to report on the malware that would later become known as Stuxnet. In 2012, he was cited in a follow-up to another breach of credit and debit card data, in this case potentially more than 10 million Visa and MasterCard accounts with transactions handled by Global Payments Inc. of Atlanta, Georgia.

Worked examples

Example 1 — a first encounter with Brian Krebs

Start with the simplest possible case. Write down what Brian Krebs claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Brian Krebs before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Brian Krebs ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Brian Krebs

In research
Brian Krebs appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Brian Krebs in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Brian Krebs is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1972 births, American activist journalists, American business and financial journalists, so understanding it makes those chapters shorter.
In everyday life
Look for Brian Krebs outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
