Crooks Need Just Six Seconds To Guess A Credit Card Number (independent.co.uk) 68

schwit1 quotes The Independent: Criminals can work out the card number, expiration date, and security code for a Visa debit or credit card in as little as six seconds using guesswork, researchers have found... Fraudsters use a so-called Distributed Guessing Attack to get around security features put in place to stop online fraud, and this may have been the method used in the recent Tesco Bank hack...

According to a study published in the academic journal IEEE Security & Privacy, fraudsters could use computers to systematically fire different variations of security data at hundreds of websites simultaneously. Within seconds, by a process of elimination, the criminals could verify the correct card number, expiration date and the three-digit security number on the back of the card.

One of the researchers explained this attack combines two weaknesses into one powerful attack. "Firstly, current online payment systems do not detect multiple invalid payment requests from different websites... Secondly, different websites ask for different variations in the card data fields to validate an online purchase. This means it's quite easy to build up the information and piece it together like a jigsaw puzzle."

iOS's 'Activation Lock' For Stolen iPads And iPhones Can Be Easily Bypassed (computerworld.com) 51

An anonymous reader quotes ComputerWorld: Two researchers claim to have found a way to bypass the activation lock feature in iOS that's supposed to prevent anyone from using an iPhone or iPad marked as lost by its owner... One of the few things allowed from the activation lock screen is connecting the device to a Wi-Fi network, including manually configuring one. [Security researcher] Hemanth had the idea of trying to crash the service that enforces the lock screen by entering very long strings of characters in the WPA2-Enterprise username and password fields.

The researcher claims that, after awhile, the screen froze, and he used the iPad smart cover sold by Apple to put the tablet to sleep and then reopen it... "After 20-25 seconds the Add Wifi Connection screen crashed to the iPad home screen, thereby bypassing the so-called Find My iPhone Activation Lock," he said in a blog post.

There's also a five-minute video on YouTube which purports to show a newer version of the same attack.

Encryption Backdoor Sneaks Into UK Law (theregister.co.uk) 117

Coisiche found a disturbing article from The Register about the U.K.'s new "Snoopers' Charter" law that has implications for tech companies around the world: Among the many unpleasant things in the Investigatory Powers Act that was officially signed into law this week, one that has not gained as much attention is the apparent ability for the U.K. government to undermine encryption and demand surveillance backdoors... As per the final wording of the law, comms providers on the receiving end of a "technical capacity notice" will be obliged to do various things on demand for government snoops -- such as disclosing details of any system upgrades and removing "electronic protection" on encrypted communications. Thus, by "technical capability," the government really means backdoors and deliberate security weaknesses so citizens' encrypted online activities can be intercepted, deciphered and monitored... At the end of the day, will the U.K. security services be able to read your email, your messages, your posts and private tweets, and your communications if they believe you pose a threat to national security? Yes, they will.
The bill added the Secretaries of State as a required signatory to the "technical capacity" notices, which "introduces a minor choke-point and a degree of accountability." But the article argues the law ultimately anticipates the breaking of encryption, and without customer notification. "The U.K. government can certainly insist that a company not based in the U.K. carry out its orders -- that situation is specifically included in the new law -- but as to whether it can realistically impose such a requirement, well, that will come down to how far those companies are willing to push back and how much they are willing to walk away from the U.K. market."

The 'USB Killer' Has Been Mass Produced -- Available Online For About $50 (arstechnica.com) 216

New submitter npslider writes: The "USB Killer," a USB stick that fries almost everything that it is plugged into, has been mass produced -- available online for about $50. Ars Technica first wrote about this diabolical device that looks like a fairly humdrum memory stick a year ago. From the report: "The USB Killer is shockingly simple in its operation. As soon as you plug it in, a DC-to-DC converter starts drawing power from the host system and storing electricity in its bank of capacitors (the square-shaped components). When the capacitors reach a potential of -220V, the device dumps all of that electricity into the USB data lines, most likely frying whatever is on the other end. If the host doesn't just roll over and die, the USB stick does the charge-discharge process again and again until it sizzles. Since the USB Killer has gone on sale, it has been used to fry laptops (including an old ThinkPad and a brand new MacBook Pro), an Xbox One, the new Google Pixel phone, and some cars (infotainment units, rather than whole cars... for now). Notably, some devices fare better than others, and there's a range of possible outcomes -- the USB Killer doesn't just nuke everything completely." You can watch a video of EverythingApplePro using the USB Killer to fry a variety of electronic devices. It looks like the only real defense from the USB Killer is physically capping your ports.

Hackers Steal $31 Million at Russia's Central Bank (cnn.com) 76

The Bank of Russia has confirmed Friday that hackers have stolen 2 billion rubles ($31 million) from correspondent accounts at the Russian central bank. Central bank security executive Artiom Sychev said it could've been much worse as hackers tried to steal 5 billion rubles, but the central banking authority managed to stop them. CNNMoney reports: Hackers also targeted the private banks and stole cash from their clients, the central bank reported. The central bank did not say when the heist occurred or how hackers moved the funds. But so far, the attack bears some similarity to a recent string of heists that has targeted the worldwide financial system. Researchers at the cybersecurity firm Symantec have concluded that the global banking system has been under sustained attack from a sophisticated group -- dubbed "Lazarus" -- that has been linked to North Korea. But it's unclear who has attacked Russian banks this time around. Earlier Friday, the Russian government claimed it had foiled an attempt to erode public confidence in its financial system. Russian's top law enforcement agency, the FSB, said hackers were planning to use a collection of computer servers in the Netherlands to attack Russian banks. Typically, hackers use this kind of infrastructure to launch a "denial of service" attack, which disrupts websites and business operations by flooding a target with data. The FSB said hackers also planned to spread fake news about Russian banks, sending mass text messages and publishing stories on social media questioning their financial stability and licenses to operate.

Fake Apple Chargers Fail Safety Tests (bbc.com) 115

Investigators have warned consumers they face potentially fatal risks after 99% of fake Apple chargers failed a basic safety test. From a report on BBC: Trading Standards, which commissioned the checks, said counterfeit electrical goods bought online were an "unknown entity." Of 400 counterfeit chargers, only three were found to have enough insulation to protect against electric shocks. It comes as Apple has complained of a "flood" of fakes being sold on Amazon. Apple revealed in October that it was suing a third-party vendor, which it said was putting customers "at risk" by selling power adapters masquerading as those sold by the Californian tech firm.

Russia Says Foreign Spies Plan Cyber Attack On Banking System (reuters.com) 86

Russia said on Friday it had uncovered a plot by foreign spy agencies to sow chaos in Russia's banking system via a coordinated wave of cyber attacks and fake social media reports about banks going bust. From a report on Reuters: Russia's domestic intelligence agency, the Federal Security Service (FSB), said that the servers to be used in the alleged cyber attack were located in the Netherlands and registered to a Ukrainian web hosting company called BlazingFast. The attack, which was to target major national and provincial banks in several Russian cities, was meant to start on Dec. 5, the FSB said in a statement. "It was planned that the cyber attack would be accompanied by a mass send-out of SMS messages and publications in social media of a provocative nature regarding a crisis in the Russian banking system, bankruptcies and license withdrawals," it said. "The FSB is carrying out the necessary measures to neutralize threats to Russia's economic and information security."

UK Homes Lose Internet Access After Cyber-Attack (theguardian.com) 33

More than 100,000 people in the UK have had their internet access cut after a string of service providers were hit by what is believed to be a coordinated cyber-attack, taking the number affected in Europe up to about a million. From a report on The Guardian, shared by reader JoshTops: TalkTalk, one of Britain's biggest service providers, the Post Office and the Hull-based KCom were all affected by the malware known as the Mirai worm, which is spread via compromised computers. The Post Office said 100,000 customers had experienced problems since the attack began on Sunday and KCom put its figure at about 10,000 customers since Saturday. Earlier this week, Germany's Deutsche Telekom said up to 900,000 of its customers had lost their internet connection as part of the same incident.

Multiple Vulnerabilities In AirDroid Opens At Least 10 Million Android Users To MITM Attacks, Hijackings (androidpolice.com) 29

AirDroid is a popular Android application that allows users to send and receive text messages and transfer files and see notifications from their computer. Zimperium, a mobile security company, recently released details of several major security vulnerabilities in the application, allowing attackers on the same network to access user information and execute code on a user's device. Since there are between 10 and 50 million installations of the app, many users may be imperiled by AirDroid. Android Police reports: The security issues are mainly due to AirDroid using the same HTTP request to authorize the device and send usage statistics. The request is encrypted, but uses a hardcoded key in the AirDroid application (so essentially, everyone using AirDroid has the same key). Attackers on the same network an intercept the authentication request (commonly known as a Man-in-the-middle attack) using the key extracted from any AirDroid APK to retrieve private account information. This includes the email address and password associated with the AirDroid account. Attackers using a transparent proxy can intercept the network request AirDroid sends to check for add-on updates, and inject any APK they want. AirDroid would then notify the user of an add-on update, then download the malicious APK and ask the user to accept the installation. Zimperium notified AirDroid of these security flaws on May 24, and a few days later, AirDroid acknowledged the problem. Zimperium continued to follow up until AirDroid informed them of the upcoming 4.0 release, which was made available last month. Zimperium later discovered that version 4.0 still had all these same issues, and finally went public with the security vulnerabilities today.

International Authorities Take Down Massive 'Avalanche' Botnet, Sinkhole Over 800,000 Domains (arstechnica.com) 53

plover writes: Investigators from the U.S. Department of Justice, the FBI, Eurojust, Europol, and other global partners announced the takedown of a massive botnet named "Avalanche," estimated to have involved as many as 500,000 infected computers worldwide on a daily basis. A Europol release says: "The global effort to take down this network involved the crucial support of prosecutors and investigators from 30 countries. As a result, five individuals were arrested, 37 premises were searched, and 39 servers were seized. Victims of malware infections were identified in over 180 countries. In addition, 221 servers were put offline through abuse notifications sent to the hosting providers. The operation marks the largest-ever use of sinkholing to combat botnet infrastructures and is unprecedented in its scale, with over 800,000 domains seized, sinkholed or blocked." Sean Gallagher writes via Ars Technica: "The domains seized have been 'sinkholed' to terminate the operation of the botnet, which is estimated to have spanned over hundreds of thousands of compromised computers around the world. The Justice Department's Office for the Western Federal District of Pennsylvania and the FBI's Pittsburgh office led the U.S. portion of the takedown. 'The monetary losses associated with malware attacks conducted over the Avalanche network are estimated to be in the hundreds of millions of dollars worldwide, although exact calculations are difficult due to the high number of malware families present on the network,' the FBI and DOJ said in their joint statement. In 2010, an Anti-Phishing Working Group report called out Avalanche as 'the world's most prolific phishing gang,' noting that the Avalanche botnet was responsible for two-thirds of all phishing attacks recorded in the second half of 2009 (84,250 out of 126,697). 'During that time, it targeted more than 40 major financial institutions, online services, and job search providers,' APWG reported. In December of 2009, the network used 959 distinct domains for its phishing campaigns. Avalanche also actively spread the Zeus financial fraud botnet at the time."

'Fatal' Flaws Found in Medical Implant Software (bbc.com) 38

Security researchers have warned of flaws in medical implants in what they say could have fatal consequences. The flaws were found in the radio-based communications used to update implants, including pacemakers, and read data from them. From a BBC report:By exploiting the flaws, the researchers were able to adjust settings and even switch off gadgets. The attacks were also able to steal confidential data about patients and their health history. A software patch has been created to help thwart any real-world attacks. The flaws were found by an international team of security researchers based at the University of Leuven in Belgium and the University of Birmingham.

Destructive Hacks Strike Saudi Arabia, Posing Challenge to Trump (bloomberg.com) 184

State-sponsored hackers have conducted a series of destructive attacks on Saudi Arabia over the last two weeks, erasing data and wreaking havoc in the computer banks of the agency running the country's airports and hitting five additional targets, according to two people familiar with an investigation into the breach. From a report on Bloomberg: Saudi Arabia said after inquiries from Bloomberg News that "several" government agencies were targeted in attacks that came from outside the kingdom, according to state media. Although a probe by Saudi authorities is still in its early stages, the people said digital evidence suggests the attacks emanated from Iran. That could present President-elect Donald Trump with a major national security challenge as he steps into the Oval Office. The use of offensive cyber weapons by a nation is relatively rare and the scale of the latest attacks could trigger a tit-for-tat cyber war in a region where capabilities have mushroomed ever since an attack on Saudi Aramco in 2012.

Firefox Zero-Day Can Be Used To Unmask Tor Browser Users (computerworld.com) 55

An anonymous reader quotes a report from Computerworld: A Firefox zero-day being used in the wild to target Tor users is using code that is nearly identical to what the FBI used in 2013 to unmask Tor-users. A Tor browser user notified the Tor mailing list of the newly discovered exploit, posting the exploit code to the mailing list via a Sigaint darknet email address. A short time later, Roger Dingledine, co-founder of the Tor Project Team, confirmed that the Firefox team had been notified, had "found the bug" and were "working on a patch." On Monday, Mozilla released a security update to close off a different critical vulnerability in Firefox. Dan Guido, CEO of TrailofBits, noted on Twitter, that "it's a garden variety use-after-free, not a heap overflow" and it's "not an advanced exploit." He added that the vulnerability is also present on the Mac OS, "but the exploit does not include support for targeting any operating system but Windows." Security researcher Joshua Yabut told Ars Technica that the exploit code is "100% effective for remote code execution on Windows systems." "The shellcode used is almost exactly the shellcode of the 2013 one," tweeted a security researcher going by TheWack0lian. He added, "When I first noticed the old shellcode was so similar, I had to double-check the dates to make sure I wasn't looking at a 3-year-old post." He's referring to the 2013 payload used by the FBI to deanonymize Tor-users visiting a child porn site. The attack allowed the FBI to tag Tor browser users who believed they were anonymous while visiting a "hidden" child porn site on Freedom Hosting; the exploit code forced the browser to send information such as MAC address, hostname and IP address to a third-party server with a public IP address; the feds could use that data to obtain users' identities via their ISPs.

Trump Will Get Power To Send Unblockable Mass Text Messages To All Americans (nymag.com) 550

President-elect Donald Trump will have access to a system which can send unblockable texts to every phone in the United States once he becomes the president. From a report on NYMag: These 90-character messages, known as Wireless Emergency Alerts (or WEAs), are part of a program put in place after Congress passed the Warning, Alert, and Response Network (WARN) Act, in 2006. WEAs allow for targeted messages to be sent to every cell phone getting a signal from certain geographically relevant cell towers (or, in a national emergency, all of them). While it'd be a true nightmare to get screeching alerts from your phone that "Loser Senate Democrats still won't confirm great man Peter Thiel to Supreme Court. Sad!", there are some checks and balances on this. While President-elect Trump hasn't shown much impulse control when it comes to his favorite mass-messaging service, Twitter, the process for issuing a WEA isn't as simple as typing out a 90-character alert from a presidential smartphone and hitting "Send." All WEAs must be issued through FEMA's Integrated Public Alert Warning System, meaning that an emergency alert from the president still has at least one layer to pass through before being issued. While FEMA is under control of the executive branch (the head of FEMA is selected by the president, and reports to the Department of Homeland Security), the agency would have a vested interest in not seeing their alert system bent toward, uh, non-emergency ends.

SourceForge Introduces HTTPS Support For Project Websites (sourceforge.net) 43

SourceForge announced on Wednesday that it is introducing HTTPS for all project websites on its platform. Once a project has been moved to HTTPS, old domain will automatically redirect to their new counterparts, resulting in no loss of traffic or inconvenience. From a blog post on the site: With a single click, projects can opt-in to switch their web hosting from http://name.sourceforge.net to https://name.sourceforge.io. Project admins can find this option in the Admin page, under "HTTPS", naturally.There's also a guide to assist developers with the transition. SourceForge launched HTTPS support for SourceForge.net back in February, but this rolls out HTTPS support to individual project websites hosted on SourceForge. There's also a Site News section on the website now where you can read about all SourceForge changes and improvements over the past year since SourceForge was acquired by BIZX, such as eliminating the DevShare program and scanning all projects for malware.

More Than 1 Million Android Devices Rooted By Gooligan Malware (onthewire.io) 42

Reader Trailrunner7 writes: A new version of an existing piece of malware has emerged in some third-party Android app stores and researchers say it has infected more than a million devices around the world, giving the attackers full access to victims' Google accounts in the process. The malware campaign, known as Gooligan, is a variant of older malware called Ghost Push that has been found in many malicious apps. Researchers at Check Point recently discovered several dozen apps, mainly in third-party app stores, that contain the malware, which is designed to download and install other apps and generate income for the attackers through click fraud. The malware uses phantom clicks on ads to generate revenue for the attackers through pay-per-install schemes, but that's not the main concern for victims. The Gooligan malware also employs exploits that take advantage of several known vulnerabilities in older versions of Android, including Kit Kat and Lollipop to install a rootlet that is capable of stealing users' Google credentials.Although the malware has full remote access to infected devices, it doesn't appear to be stealing user data, but rather is content to go the click-fraud route. Most users are being infected through the installation of apps that appear to be legitimate but contain the Gooligan code, a familiar infection routine for mobile devices.

Muni System Hacker Hit Others By Scanning For Year-Old Java Vulnerability (arstechnica.com) 30

An anonymous reader quotes a report from Ars Technica: The attacker who infected servers and desktop computers at the San Francisco Metropolitan Transit Agency (SFMTA) with ransomware on November 25 apparently gained access to the agency's network by way of a known vulnerability in an Oracle WebLogic server. That vulnerability is similar to the one used to hack a Maryland hospital network's systems in April and infect multiple hospitals with crypto-ransomware. And evidence suggests that SFMTA wasn't specifically targeted by the attackers; the agency just came up as a target of opportunity through a vulnerability scan. In an e-mail to Ars, SFMTA spokesperson Paul Rose said that on November 25, "we became aware of a potential security issue with our computer systems, including e-mail." The ransomware "encrypted some systems mainly affecting computer workstations," he said, "as well as access to various systems. However, the SFMTA network was not breached from the outside, nor did hackers gain entry through our firewalls. Muni operations and safety were not affected. Our customer payment systems were not hacked. Also, despite media reports, no data was accessed from any of our servers." That description of the ransomware attack is not consistent with some of the evidence of previous ransomware attacks by those behind the SFMTA incident -- which Rose said primarily affected about 900 desktop computers throughout the agency. Based on communications uncovered from the ransomware operator behind the Muni attack published by security reporter Brian Krebs, an SFMTA Web-facing server was likely compromised by what is referred to as a "deserialization" attack after it was identified by a vulnerability scan. A security researcher told Krebs that he had been able to gain access to the mailbox used in the malware attack on the Russian e-mail and search provider Yandex by guessing its owner's security question, and he provided details from the mailbox and another linked mailbox on Yandex. Based on details found in e-mails for the accounts, the attacker ran a server loaded with open source vulnerability scanning tools to identify and compromise servers to use in spreading the ransomware, known as HDDCryptor and Mamba, within multiple organizations' networks.

Holding Shift + F10 During Windows 10 Updates Opens Root CLI, Bypasses BitLocker (bleepingcomputer.com) 138

An anonymous reader quotes a report from BleepingComputer: Windows security expert and infrastructure trainer Sami Laiho says that by holding SHIFT + F10 while a Windows 10 computer is installing a new OS build, an attacker can open a command-line interface with SYSTEM privileges. This CLI debugging interface also grants the attacker full access to the computer's hard drive data, despite the presence of BitLocker. The CLI debugging interface is present when updating to new Windows 10 and Windows 10 Insiders builds. The most obvious exploitation scenario is when a user leaves his computer unattended during the update procedure. A malicious insider can open the CLI debugger and perform malicious operations under a root user, despite BitLocker's presence. But there are other scenarios where Laiho's SHIFT + F10 trick can come in handy. For example when police have seized computers from users who deployed BitLocker or when someone steals your laptop. Windows 10 defaults help police/thieves in this case because these defaults forcibly update computers, even if the user hasn't logged on for weeks or months. This CLI debugging interface grants the attacker full access to the computer's hard drive, despite the presence of BitLocker. The reason is that during the Windows 10 update procedure, the OS disables BitLocker while the Windows PE (Preinstallation Environment) installs a new image of the main Windows 10 operating system. "This [update procedure] has a feature for troubleshooting that allows you to press SHIFT + F10 to get a Command Prompt," Laiho writes on his blog. "The real issue here is the Elevation of Privilege that takes a non-admin to SYSTEM (the root of Windows) even on a BitLocker (Microsoft's hard disk encryption) protected machine." Laiho informed Microsoft of the issue and the company is apparently working on a fix.

The Internet Archive Is Building a Canadian Copy To Protect Itself From Trump (theverge.com) 586

The Internet Archive, a digital library nonprofit that preserves billions of webpages for the historical record, is building a backup archive in Canada after the election of Donald Trump. The Verge adds: Today, it began collecting donations for the Internet Archive of Canada, intended to create a copy of the archive outside the United States. "On November 9th in America, we woke up to a new administration promising radical change," writes founder Brewster Kahle. "It was a firm reminder that institutions like ours, built for the long-term, need to design for change. For us, it means keeping our cultural materials safe, private and perpetually accessible. It means preparing for a web that may face greater restrictions. It means serving patrons in a world in which government surveillance is not going away; indeed it looks like it will increase."

It's Not Just You, iCloud Calendar Spam is On the Rise (techcrunch.com) 28

New submitter petersike writes: If you're using iCloud to sync your calendar across your devices, chances are you just received a bunch of spammy invites over the last few days. Many users are reporting fake events about Black Friday 'deals' coming from Chinese users. If you're looking for cheap Ray-Ban or Louis Vuitton knockoffs, you might find these invites useful. Otherwise, you might be wondering: why is this a thing? If you use your calendar for work, you already rely on calendar invites to invite other people to meetings and events. All major calendar backends support this feature -- Google Calendar, Microsoft Exchange and Apple's iCloud. And it's quite a convenient feature as you only need to enter an email address to send these invitations. You don't need to be in the same company or even in your recipient's address book. But it's also yet another inbox -- and like every inbox out there, it can get abused.
