When Aran Khanna was a college student, he accepted an internship to work at Facebook. Even before his internship started, he started playing around with Facebook’s APIs and applications. Aran built a Chrome extension called Marauder’s Map, which used Facebook Messenger’s web APIs to track where people lived, what their schedule was, and other highly The post Digital Privacy with Aran Khanna appea...

If you have ever stayed in a short-term rental (like an Airbnb, HomeAway, or CouchSurfing), you have probably used the wifi network at that rental property. Why wouldn’t you? It’s no different than hopping on an open wifi network at an airport, or a Starbucks, or your friend’s house, right? One major difference: the hardware The post Hacking Your Short-Term Rental with Jeremy Galloway appeared fir...

Last year, the WannaCry ransomware attack shut down hospitals, public transportation systems, and governments, demanding payment to unlock key computer systems. A programmer named Marcus Hutchins was able to stop WannaCry by registering a DNS entry buried in the WannaCry code. Not long after he stopped the WannaCry attack, Marcus Hutchins was arrested at a The post WannaCry’s Gray Hat with Reeves...

Employees often find themselves needing to do work outside of the office. Depending on the sensitivity of your task, accessing internal systems from a remote location may or may not be OK. If you are using a corporate application that shows the menu of your company’s cafe on your smartphone, your workload is less sensitive.

Last month, Software Engineering Daily had our 4th Meetup at Cloudflare in San Francisco. For this Meetup, the format was short interviews with security specialists from Pinterest, Cloudflare, and Segment. Each of these companies has unique security challenges, but they also have overlap in their security strategies. Nick Sullivan, Amine Kamel, and Evan Johnson are The post Web Security at Cloudfl...

Military force is powered by software. The drones that are used to kill suspected terrorists can identify those terrorists using the same computer vision tools that are used to identify who is in an Instagram picture. Nuclear facilities in Iran were physically disabled by the military-sponsored Stuxnet virus. National intelligence data is collected and processed The post Modern War with Peter Warr...

When I log into my bank account from my laptop, I first enter my banking password. Then the bank sends a text message to my phone with a unique code, and I enter that code into my computer to finish the login. This login process is two-factor authentication. I am proving my identity by entering The post Secure Authentication with Praneet Sharma appeared first on Software Engineering Daily .

Public key encryption allows for encrypted, private messages. A message sent from Bob to Alice gets encrypted using Alice’s public key. Public key encryption also allows for signed messages–so that when Alice signs a message, Alice uses her private key and Bob can verify it if Bob has her public key. In both cases, Bob The post Keybase with Max Krohn appeared first on Software Engineering Da...

A smart contract is a program that allows for financial transactions. Smart contracts are usually associated with the Ethereum platform, which has a language called Solidity that makes it easy to program smart contracts. Someday, we will have smart contracts issuing insurance, processing legal claims, and executing accounting transactions. Smart contracts involve money, and they The post Smart Con...

Static analysis is the process of evaluating code for errors, memory leaks, and security vulnerabilities. The “static” part refers to the fact that the code is not running. This differentiates it from unit tests and integration tests, which evaluate the runtime characteristics of code. If you use an IDE or a linter, you are using The post Static Analysis with Paul Anderson appeared first on Softwa...

Online advertising enables free content and services of the Internet. One of the free services that is powered by advertising is the browser. 60% of web browsing is done through Chrome, which is owned by Google, which is powered by advertising. The application that most of us use to explore the web is made by The post Brave Browser with Jonathan Sampson appeared first on Software Engineering Daily...

When a cyber attack occurs, how do we identify who committed it? There is no straightforward answer to that question. Even if we know Chinese hackers have infiltrated our power grid with logic bombs, we might not be able to say with certainty whether those hackers were state actors or rogue Chinese hackers looking for The post Attack Attribution with John Davis appeared first on Software Engineeri...

Ransomware and DDoS attacks happen all the time. Sometimes they affect large swaths of users. WannaCry ransomware froze the computer systems in hospitals. Mirai botnet DDoS attacks took down a DNS provider, making Netflix and Twitter inaccessible for a short period of time. These are innocent attacks compared to what we could face from a The post Car and IoT Security with Chris Craig appeared firs...

Quality assurance testing is a form of testing that closely mirrors user behavior. Sometimes it is manual, sometimes it is automated. Automated QA tests are scripts that validate correct data representation as the application mechanically runs through high-level workflows–like a login page. Manual QA testers act out use cases of an application to see if The post QA Testing with Jonathan Alex...

Shopify is a company that helps customers build custom online storefronts. Shopify has built upon the same Ruby on Rails application since the founding of their business 12 years ago starting with Rails 0.5 and moving all the way to Rails 5.   MRuby is a lightweight implementation of the Ruby language. Shopify made the The post MRuby and Language Security with Daniel Bovensiepen appeared first on...

At Coinbase, security is more important than anything else. Coinbase is a company that allows for storage and exchange of cryptocurrencies. Protecting banking infrastructure is difficult, but in some ways the stakes are higher with Coinbase, because bitcoin is fundamentally unregulated. If a hacker were able to syphon all of the money out of Coinbase The post Coinbase Security with Philip Martin a...

A cryptocurrency exchange faces a uniquely difficult fraud problem. A hacker who steals my credentials can initiate a transfer of all my bitcoin to another wallet, and it is a non-reversible, non-identifiable payment. So it is really important to prevent those kinds of fraudulent transactions. At the third Software Engineering Daily Meetup, Coinbase director of The post Fighting Fraud at Coinbase...

Ransomware uses software to extort people. A piece of ransomware might arrive in your inbox looking like a PDF, or a link to a website with a redirect. Ransomware is often distributed using social engineering. The email address might resemble someone you know, or a transactional email from a company like Uber or Amazon.

The online advertising industry is a giant casino. Giant technology companies are the casino owners, online publishers are the casino employees, the brand advertisers are the victims who keep returning to the casino to lose their money, and the small adtech companies are the sharks who make lots of money exploiting the inefficiencies of the The post Ad Fraud In Our Own Backyard with Shailin Dhar a...

The Internet is decreasing in privacy and increasing in utility. Under some conditions, this tradeoff makes sense. We publicize our profile photo so that people know what we look like. Under other conditions, this tradeoff does not make sense. We do not want a television that costs less to purchase because it is silently recording The post Web Tracking with Bill Budington appeared first on Softwar...

Thursday February 23rd was a big day in security news: details were published about the Cloudbleed bug, which leaked tons of plaintext requests from across the Internet into plain view. On the same day, the first collision attack against SHA-1 was demonstrated by researchers at Google, foretelling the demise of SHA-1 as a safe hashing The post Cloudbleed and SHA-1 Collision with Max Burkhardt appe...

Security vulnerabilities are an important concern in systems. When we specify that we want certain information hidden, for example our phone number or our date of birth, we expect the system to hide the information. However, this doesn’t always happen due to human error in the code because programmers have to write checks and filters The post Security Language with Jean Yang appeared first on Soft...

Vulnerabilities exist in every computer system. As a system gets bigger, the number of vulnerabilities magnifies. The web is the biggest, most complex computer system we have–but fortunately, the steps we can take to secure our web applications are often quite simple. Jared Smith is a cyber security research scientist with Oak Ridge National Laboratory. The post Cyber Warfare with Jared Smit...

Every digital system has vulnerabilities. Cars can be hacked, locked computers can be exploited, and credit cards can be spoofed. Security researchers make a career out of finding these types of vulnerabilities. Samy Kamkar’s approach to security research is not just about dissection–it’s also about creativity. For many of the technologies he hacks on, Samy The post Security Research with Sa...

A huge percentage of online advertisements are never seen by humans. They are viewed by bots–automated scripts that are opening web pages in a browser and pretending to be a human. Advertising scammers set up web pages, embed advertisements on those pages, and then pay for bot traffic to come and view those advertisements.
