In recent weeks, major bank websites around the world have experienced outages after being have been hit with Distributed Denial of Service (DDoS) attacks. Although few, if any, of these banks have been totally knocked offline, these DoS attacks have dramatically slowed the response time of their websites to legitimate customers. The most recent victim was the Royal Bank of Scotland. Due to this attack, RBS customers were unable to access their accounts for about an hour last week.
With a tiny computer, hackers can see every website you visit, exploit services on the network, and break into your Wi-Fi router's gateway to manipulate sensitive settings. These attacks can be performed from anywhere once the attacker's computer has been connected to the router via a network implant.
If you're worried about the security of your Mac, there are easy measures to prevent the most dangerous attacks. Named after the tactic of accessing an unattended computer in a hotel room, we can thwart "evil maid" attacks with Do Not Disturb and LuLu, free macOS tools by Objective-See that keep an eye on unattended computers and flag suspicious network connections that indicate a malware infection.
Hackers and makers are often grouped under the same label. While hackers draw on computer science skills to write programs and find bugs, makers use electrical engineering to create hardware prototypes from microprocessor boards like the Arduino. We'll exercise both sets of skills to program a $6 NodeMCU to display the status of a Wi-Fi link via an LED, allowing us to monitor for jamming attacks.
Null Byte users have often requested video content, but the question has always been what format would best serve our community. This week, we partnered with Null Space Labs, a hackerspace in Los Angeles, to test the waters by hosting a series of talks on ethical hacking for students in Pasadena Computer Science Club. We invited students and Null Byte writers to deliver talks on Wi-Fi hacking, MITM attacks, and rogue devices like the USB Rubber Ducky.
Using Hydra, Ncrack, and other brute-forcing tools to crack passwords for the first time can be frustrating and confusing. To ease into the process, let's discuss automating and optimizing brute-force attacks for potentially vulnerable services such as SMTP, SSH, IMAP, and FTP discovered by Nmap, a popular network scanning utility.
Hacker's are always looking for new ways to exploit systems and exfiltrate passwords, even in hashed form. Sophisticated brute-force attacks powered by high-end GPUs can perform millions of password attempts per second. But Ubuntu and Debian users aren't completely helpless. There are ways to harden the hashed password to better defend against Hashcat attacks.
Good day people, today we will examine some basic, for some people well-known attacks, also we will take a look at some advanced attacks.
Yesterday, we pointed out that hackers could remote-wipe certain Android-based Samsung smartphones like the Galaxy S III using a USSD exploit. All they have to do is hide a small code into any webpage or text—even barcodes—then once you click on it, the phone resets to factory settings in a matter of seconds. The video below shows just how easy it is.
It's important to know who you're dealing with after hacking your target's MacBook. Getting remote access is simple, but covertly gathering information about the user and their system can be a challenge.
In our previous article, we learned how to take advantage of a feature, Dynamic Data Exchange (DDE), to run malicious code when an MS Word document is opened. Because Microsoft built DDE into all of its Office products as a way to transfer data one time or continuously between applications, we can do the same thing in Excel to create a spreadsheet that runs malicious code when opened. The best part is, it will do so without requiring macros to be enabled.
In October of 2017, Mathy Vanhoef released "Key Reinstallation Attacks: Forcing Nonce Reuse in WPA2." This paper demonstrates a way to decrypt traffic on practically any WPA2 network, the most commonly used form of wireless security (seeing as all other forms of Wi-Fi encryption have already been broken). Practically all of the network-connected devices we use will need to be updated in some way in order to protect against this vulnerability, each of them in a different way.
Security journalist Brian Krebs recently suffered a record-breaking DDoS attack to his his website, clocking in at or near a whopping 620 Gbps of traffic. Krebs' site was down for over 24 hours, and it resulted in him having to leave his CDN behind.
Heart disease is the leading cause of death of men and women in the US. Over half a million Americans die from it annually. Atherosclerosis — a build up of plaque in the arteries — is a common feature of heart disease and can be caused by smoking, fats and cholesterol in the blood, diabetes, and high blood pressure.
Next to spam calls, few things are more annoying than being inundated with spam, scam, and smishing texts. Your iPhone's Messages app should be a place for your friends and family to stay in touch, not a minefield of phishing attacks, malicious links, and viruses. Luckily, there are quite a few methods to block and report your way to a more spam-free iPhone.
Although there has been much speculation about how much damage could be done if hackers were to take control of a country's SCADA systems, there have been few examples - until a few months ago, with the power outage in Ukraine caused by hackers.
NMAP is an essential tool in any hacker's arsenal. Originally written by Gordon Lyon aka Fydor, it's used to locate hosts and services and create a map of the network. NMAP has always been an incredibly powerful tool, but with it's newest release, which dropped mid-November of last year, they've really out done themselves.
Those of you who have been a part of the Null Byte community for even a short while know that I sincerely and firmly believe that hacking is the most important skill set of the future.
The first few minutes after gaining access to a MacBook are critical — but where do we begin? Using tools built into macOS, we can develop an in-depth understanding of running background processes, detect antivirus software, locate sensitive files, and fingerprint other devices on the network. All of this can be done without installing additional software or modifying any files.
It's September 1st, 1859, and the Earth looks more or less like something out of an apocalyptic movie or Sci-Fi novel. All communications have failed, it's so bright outside at midnight that people are getting up and making breakfast, and people all over the world are seeing auroras. The solar storm that produced the electromagnetic pulse and caused all this mayhem is known as the Carrington Event, and storms like it happen about about once every century.
In a previous article, we learned how to take advantage of a feature, Dynamic Data Exchange (DDE), to run malicious code when a Microsoft Word document is opened. The biggest challenge of this attack is that it requires getting the user to agree to a pop-up prompt. Fortunately, since I posted that article, many new obfuscation techniques have been discovered to make this easier. Today, we explore and combine some of them to make the ultimate hidden DDE attack.
Snapchat is probably used to Facebook copying its features by now, but Apple borrowing a page out of its playbook is likely a bit more surprising.
A recently discovered bug in iOS 8's Mail app by Jan Soucek can allow the maliciously-minded to quite easily phish your iCloud password without you ever thinking something has gone awry. Using a bug that allows remote HTML content to be loaded in place of the original email content, unsuspecting victims would be prompted for iCloud credentials in a popup that resembles the native one found on iOS.
ESP8266-based microcontrollers can be used to create exciting and legal Wi-Fi hacking games to test your or your friends' Wi-Fi hacking skills.
There are hidden Wi-Fi networks all around you — networks that will never show up in the list of available unlocked and password-protected hotspots that your phone or computer can see — but are they more secure than regular networks that broadcast their name to any nearby device?
Whoop, there it is. McDonald's makes its food even faster by partnering with UberEats to bring orders to your doorstep in over 1,000 locations around the country.
A man-in-the-middle attack, or MitM attack, is when a hacker gets on a network and forces all nearby devices to connect to their machine directly. This lets them spy on traffic and even modify certain things. Bettercap is one tool that can be used for these types of MitM attacks, but Xerosploit can automate high-level functions that would normally take more configuration work in Bettercap.
Welcome back, my nascent Hackers! In my last blog, we looked at a passive way to gather information necessary for a hack. The advantage of using passive recon is that it's totally undetectable, meaning that the target never knows you're scouting them and you leave no tracks. The disadvantage, of course, is that it's limited to only some websites and not entirely reliable.
With just two microcontrollers soldered together, you can inject keystrokes into a computer from a smartphone. After building and programming the device, you plug it into a desktop or laptop, access it over a smartphone, and inject keystrokes as you would with a USB Rubber Ducky.
