When a popular website where coders, programmers, and developers hang out in a professional and networking set-up is hacked, you’ll know that the cybersecurity problem is very real and alarming. Today, Stack Overflow, one of the largest question and answer website for programmers and developers, have disclosed that their system experienced a cyber attack and an unknown hacker(s) managed to gain unauthorized access to its production system on May 11, 2019.

The company initially said that the unknown intruders accessed no customer data, but they eventually backtracked saying that the intruder(s) may have sent requests that could return with some of the sensitive data of a small number of their users.

Founded in 2008, is the largest, most trusted online community for anyone that codes to learn, share their knowledge, and build their careers. The site has an estimated unique visitor count of 50 million each month, and they come to the website to solve coding problems, network with other programmers and developers, and find new job opportunities in the tech world.

When Stack Overflow announced that their system was compromised a few days ago, the community was shocked and was quick to ask for the extent of the breach. Initially, Stack Overflow said that there is “no evidence” that users’ data were accessed or breached and that the hacking was only contained in the site’s production system.

In a short note published by Mary Ferguson, Vice President of Engineering at Stack Overflow, the company confirmed the security breach but said that they don’t have any evidence pointing to the concern that the hackers accessed users’ data.

“Over the weekend, there was an attack on Stack Overflow. We have confirmed that some level of production access was gained on May 11. We discovered and investigated the extent of the access and are addressing all known vulnerabilities. We have not identified any breach of customer or user data,” Ferguson wrote in a blog post.

She also assured that their users’ security is important to them, and they are working hard to investigate the problem and promised to update them of any new information that comes out after their investigation.

“Our customers’ and users’ security is of the utmost importance to us. After we conclude our investigation cycle, we will provide more information,” Ferguson added.

An updated version of the investigation update posted by Ferguson in the site’s blog confirms that a bug in their system allowed an unauthorized person to gain access to their servers and said that the intrusion started from May 5 until May 11 when they discovered the unauthorized access.

“Between May 5 and May 11, the intruder contained their activities to exploration. On May 11, the intruder made a change to our system to grant themselves privileged access on production. This change was quickly identified, and we revoked their access network-wide, began investigating the intrusion, and began taking steps to remediate the intrusion,” Ferguson wrote.

In the new blog post, Ferguson confirmed her initial statement that no customer data was accessed. She said that the company maintained different servers for where they store customer data and what was obtained by the intruder. She also added that the data breach did not impact their Advertising and Talent businesses.

However, she also admits that while their general system was not compromised, they were able to “identified privileged web requests that the attacker made that could have returned IP addresses, names, or emails for a minimal number of Stack Exchange users.” The team is now reviewing their logs and assured users that they would be notified as soon as they were determined to be part of the affected users.

Moreover, Ferguson assured that the company is already taking precautionary measures such as cycling secrets, resetting company passwords, and evaluating systems and security levels. They also enlisted third-party forensic investigators to determine who is behind the data breach.

“[We are]engaging third-party forensics and incident response firm to assist us with both remediation and learnings,” Ferguson added.

Last year, another popular question and answer website similar to Stack Overflow, Quora suffered a massive data breach with hackers gaining access to sensitive information of about 100 million of its users including their names, IP address, emails, passwords, and personal messages.

A serious government press meeting has turned into the newest internet meme. Last Friday, Shaukat Ali Yousafzai, 10th Khyber Pakhtunkhwa Assembly’s Minister of Information conducted a press briefing looking like a cat. Accidentally, a cat filter was applied on Press Trust India’s (PTI) Facebook Live session coverage.

Viewers saw various government officials with pink cat ears and cartoonish whiskers. It took a few minutes before the representatives of PTI realized the mistake, despite prompts from viewers via comments on the video. After the press briefing, PTI immediately deleted the video. However, screenshots of the incident have now gone viral.

Mr. Yousafzai addressed the amusing event through a statement to the AFP news agency. He says, “I wasn’t the only one – two officials sitting along me were also hit by the cat filter.”

PTI has since released a statement through Twitter, identifying that the mistake was done by a hardworking volunteer.

In Facebook Live, applying filters is one click away. Clicking on the magic wand at the lower left corner of your phone’s screen will enable different kinds of templated masks, borders, and other effects to your video. The first option on the screen would be the most recent filters you have used.

Facebook Live on Important Events

According to a report, there are nearly two billion users per month who watched Facebook Live sessions in 2017 from its launch in 2016. It has since then become a tool favored by users. Since then, users have used Facebook Live to share important events such as weddings, birthday parties, and family reunions.  

With this kind of user engagement, governments are also noticing Facebook Live’s potential in reaching out to their voters. The Pakistan Government is not the only one using Facebook Live to stream official proceedings. Local and National governments use this tool to engage with their constituents through broadcasting events such as the signing of a bill into law and debate proceedings in the US Senate, to name a few.  

Facebook has since then developed additional tools related to public policies. This is what Katie Harbath, Facebook’s Public Policy Director, presented in the 2016 Government Social Media Conference held in Reno, Nevada. During the event, Harbath also shared that a good number of viewers in a Facebook Live session about Canada’s budgetary hearings; something that wasn’t expected at that time. In the 2016 US elections, the live-streaming video of the Presidential race (Hillary vs. Trump) had 47 million live views reaching 1.7 million viewers

Facebook Live Fails

Going viral has been a big part of internet culture. The more you have a “fail,” the more infamous you can be. Pakistan Minister’s cat filter fail is not the only incident of Facebook Live fails that has turned into a meme. In 2018, Ted Cruz broadcasted a Facebook Live with his video in portrait mode with his camera phone set up horizontally.  

Brands, even with their social media teams, are also not immune to the internet fails. Buzzfeed had a major fail back in 2016 when they had a Facebook Live interview with the then-president Barack Obama. After a lengthy introduction by host Chris Geidner, while waiting for the President, their live video feed stalled and failed to capture the interview which disappointing 35,000 Facebook viewers. The live stream of the event on Youtube, however, went well.

Consequently, there are now Youtube tutorials to help guide users on how to optimize Facebook Live and avoid these fails.

Aside from Facebook Live fails, the social media giant has been under fire since due to violent or disturbing live streams that are surfacing in the platform. Facebook has issued stricter restrictions to lessen the spreading of such videos.

CEO Mark Zuckerberg has called for support through his opinion piece in the Washington Post last May 30. He shared that Facebook, in collaboration with French officials, is creating an independent body that can help improve their content review systems. Through this initiative, Zuckerberg hopes that they can lessen, and in the future, eradicate harmful content.

More than 20 million and not 200,000 have fallen victim to a massive data breach that has seen medical clients using the services of healthcare billing company, American Medical Collection Agency (AMCA), to pay for their laboratory tests in different blood testing labs across the U.S. were confirmed by the SEC filings of affected medical institutions amidst the earlier claims of AMCA that there were fewer victims.

The data breach was a result of a cyber attack that aims to phish for financial information from the website of the AMCA. The exposed data belongs to Americans who paid laboratory services at several clinical and blood testing labs and institutions and used the AMCA billing portal.

What happened in the AMCA breach?

Data that were stolen from the victims include their names, phone numbers, dates of birth, home addresses, social security numbers, credit card numbers, and other bank details. The said information was auctioned off by the hacker in several financial hacking forums.

According to DataBreaches.net, the organization who first reported about the incident, AMCA officials, following the notification of the breach confirmed that their system has been compromised and has remained undetected for more than eight months. AMCA corroborated that the breach took place between August 1, 2018, and March 30, 2019.

Notifications have been sent by several of AMCA’s corporate partners and clients to their customers following the disclosure of the security breach that has seen information from millions of Americans compromised.

The list of impacted testing laboratories includes Quest Diagnostics (11.9 million patients), LabCorp (7.7 million patients), BioReference Laboratories (Opko Health subsidiary, 422,600 patients), Carecentrix (500,000 patients), and Sunrise Laboratories (undisclosed number of patients).

However, neither the AMCA nor its five clients have yet to notify ALL impacted citizens by the breach making them vulnerable to a lot of cyber crimes and their financial data could be used by anyone who gets hold of the information against the persons of those who still don’t know that their financial information is floating around the internet.

The companies involved in the breach are facing several lawsuits

Appropriately, the lawsuit came into the direction of AMCA, Quest, and LabCorp regarding the incident. More than 11 class-suite actions have been filed against the three companies for their inability to protect consumer data. The 11 lawsuits were recorded at The United States Judicial Panel on Multidistrict Litigation (JPML) on June 3. Since then, eight more lawsuits were filed against the companies in federal courts from New Jersey, New York, and California.

According to litigation experts, “If many cases are filed in federal court, any of the lawyers on any of those cases can file a motion with the JPML [..] to centralize the various federal cases that have been filed by sending all of them to a single judge for coordinated pre-trial proceedings.”

“Healthcare companies are especially susceptible to data breaches not only because they aggregate a tremendous amount of important and sensitive data, but also because they tend to be less focused on cybersecurity protection than other industries,” said John Yanchunis of Morgan and Morgan, one of the firms who filed lawsuits against Quest Diagnostics.

“These companies, like Quest Diagnostics, know they are at an increased risk and yet have not taken the proper steps to protect their patients’ data. We will fight for justice on behalf of those impacted by this breach,” added Yanchunis.

Lawmakers are demanding an explanation

The U.S. government, led by attorneys general from Connecticut and Illinois has also opened an investigation on the matter. Furthermore, lawmakers and other politicians have sent letters to the responding companies to ask for an explanation of why an eight-month data breach remained undetected and to demand accountability from them.

In Washington, US Sen. Mark Warner (D-VA) also sent a letter to Quest Laboratories demanding the company explain its vetting process for selecting AMCA as a billing vendor, and what requirements a third-party vendor has to pass. Democratic New Jersey Sens. Cory Booker and Bob Menendez also sent letters to AMCA, Quest, and LabCorp, seeking official answers on how a breach of this severity went undetected for eight months.

“The months-long leak leaves sensitive personal and financial information vulnerable in the hands of criminal enterprises. Moreover, such breaches force victims to contend with identity theft that may lead to irreparable harm to their credit reports and financial future,” said the letter sent by the NJ senators.

A Malware Has Been Pre-Installed In Some Cheap Android Devices, Google Confirms

Google confirms that some cheap Android devices have been found to have pre-installed malware known as Triada, which exploitis device root options. Click To Tweet

In every purchase, sometimes you can get your money’s worth, sometimes you get something more. In a recent confirmation from Google, purchase of cheap and low-end Android devices also comes with pre-installed malware and has run undetected for a couple of years.

In a press release, Google, for the first time in history, has discussed in detail the malware that is called Triada, which the tech company has confirmed have been pre-installed in several low-end Android devices including Cherry Mobile, Leagoo, and Doogee. The malware, which was first discovered and published by Kaspersky Lab back in 2016 have been pre-installed in the affected devices, meaning, the malware already existed in the device even before someone buys it.

It was believed previously that the malware was added and installed to the affected devices at some point in the supply chain process. Now, Google has revealed that cybercriminals indeed managed to compromise Android smartphones and installed a backdoor while the supply chain process of the phones was underway.

Back in 2016, Triada was simply a rooting trojan that tried to exploit the device, and after getting elevated privileges, it performed a host of different actions. To hide these actions from analysts, Triada used a combination of dynamic code loading and additional app installs. According to the press release from Google, “Triada’s first action was to install a type of superuser (su) binary file. This (su) binary allowed other apps on the device to use root permissions.”

According to Google, Triad’s purpose is to install spam apps on a device by gaining root access. However, as Google’s security feature, Google Play Protect, improves in detecting malware, Triada was able to evolve to adapt to the new challenges posed by updated security firewalls by Google. Triada is known for downloading additional Trojan components on an infected device which then steals sensitive data from banking apps, intercepts chats from messengers and social media platforms, and there are also cyber-espionage modules on the device.

“The binary accepted two passwords, od2gf04pd9 and ac32dorbdq. This is illustrated in the IDA screenshot below. Depending on which one was provided, the binary either 1) ran the command given as an argument as root or 2) concatenated all of the arguments, ran that concatenation preceded by sh, then ran them as root. Either way, the app had to know the correct password to run the command as root,” Google said.

“This Triada rooting trojan was mainly used to install apps and display ads. This trojan targeted older devices because the rooting exploits didn’t work on newer ones. Therefore, the trojan implemented a weight-watching feature to decide if old apps needed to be deleted to make space for new installs.”

Affected devices

According to recent reports, the malware has affected over 40 devices. These devices include:

  • Leagoo M5
  • Leagoo M5 Plus
  • Leagoo M5 Edge
  • Leagoo M8
  • Leagoo M8 Pro
  • Leagoo Z5C
  • Leagoo T1 Plus
  • Leagoo Z3C
  • Leagoo Z1C
  • Leagoo M9
  • ARK Benefit M8
  • Zopo Speed 7 Plus
  • UHANS A101
  • Doogee X5 Max
  • Doogee X5 Max Pro
  • Doogee Shoot 1
  • Doogee Shoot 2
  • Tecno W2
  • Homtom HT16
  • Umi London
  • Kiano Elegance 5.1
  • iLife Fivo Lite
  • Mito A39
  • Vertex Impress InTouch 4G
  • Vertex Impress Genius
  • myPhone Hammer Energy
  • Advan S5E NXT
  • Advan S4Z
  • Advan i5E
  • STF AERIAL PLUS
  • STF JOY PRO
  • Tesla SP6.2
  • Cubot Rainbow
  • EXTREME 7
  • Haier T51
  • Cherry Mobile Flare S5
  • Cherry Mobile Flare J2S
  • Cherry Mobile Flare P1
  • NOA H6
  • Pelitt T1 PLUS
  • Prestigio Grace M5 LTE
  • BQ-5510 Strike Power Max 4G (Russia)

Reportedly, Leagoo and Cubot have already removed the malware from their affected devices since March 2018. Cherry Mobile also confirmed that they removed the malware from the affected devices in 2018.

Google also said that they worked with OEMs to remove the malware from devices and rolled out the fix through OTA updates.

“By working with the OEMs and supplying them with instructions for removing the threat from devices, we reduced the spread of preinstalled Triada variants and removed infections from the devices through the OTA updates,” said Lukasz Siewierski, Android Security & Privacy Team.

“The Triada case is a good example of how Android malware authors are becoming more adept. This case also shows that it’s harder to infect Android devices, especially if the malware author requires privilege elevation.”
