The recent disclosure of a set of vulnerabilities in the Android operating system that could potentially put over 900 million devices at risk may have been patched, but its threat remains.
The QuadRooter flaw, discovered by Check Point, could potentially give cyber attackers complete control over an Android device. The vulnerability was discovered in Qualcomm chips, which are used in smartphones and tablets made by Blackberry, LG, Google and more. This put up to 900 million devices at risk. The flaw was dubbed QuadRooter because there are four interconnected flaws which can be used to gain access to the “root” of the phone, the Guardian said.
Patches to fix the flaw were made available quickly, and Check Point released an app called QuadRooter Scanner on the Google Play store which checked whether a device was at risk.
However, new research has revealed that QuadRooter’s threat is still alive. Researchers at RiskIQ have found a number of malicious apps available for download on various app stores that claim to offer a fix for the flaw, but of course do nothing of the sort.
One of these, called Fix Patch QuadRooter by KiwiApps Ltd was found in the official Google Play store. Although it was removed from there it popped up in a number of unofficial app stores, along with a number of others. In total, 27 malicious apps related to QuadRooter have so far been found.
These have been found available for download in the official Google Play store, as well as others such as BingAPK, SameAPK, AppBrain, and AppChina. All these unofficial sources carry big risks to users and their devices.
These unofficial, third-party app stores are a dangerous place; a lack of quality control means many applications are malicious, containing malware that can steal personal data. While these app stores may seem convenient for users, especially in countries where official apps may not be available, users should stick with the official Google Play Store wherever possible.

With all the frenzy around the Pokemon GO mobile game, it was only just a matter of time before attackers leveraged its popularity to spread ransomware. A new ransomware was recently discovered impersonating a Pokemon GO application for Windows. Detected by Trend Micro as Ransom_POGOTEAR.A, it appears to be like any other ransomware. However, a closer look revealed that its creators based it on Hidden Tear, an open-sourced piece of ransomware released last August 2015, with the intention of educating people.
The Pokemon GO ransomware developer designed it to create a “Hack3r” backdoor user account in Windows and is added to the Administrator group. The registry is tweaked to hide the Hack3r account from the Windows login screen. Another feature creates a network share on the victim’s computer, allowing the ransomware to spread by copying the executable to all drives. Once the executable is copied to removable drives, it creates an autorun file so the ransomware runs each time someone accesses the removable drive. The executable is also copied to the root of other fixed drives. This way, the Pokemon GO ransomware will run when the victim logs into Windows.
There are numerous indicators that the ransomware is still under development. One of them is that it has a static AES encryption key of “123vivalalgerie”. Additionally, the command & control server (C&C) uses a private IP address which means it cannot connect over the Internet.
Based on the language used by the ransom note, the Pokemon GO ransomware appears to target Arabic-speaking users, with an accompanying ransom screen that features a Pikachu image. In addition, the screensaver executable is also embedded with an image of “Sans Titre”, which is French for “Untitled”, suggesting a clue to the developer's origin.
The Hidden Tear ransomware isn’t new. In January 2015, Trend Micro discovered a hacked website in Paraguay that distributed ransomware detected as RANSOM_CRYPTEAR.B. According to the analysis, the website was compromised by a Brazilian hacker, and that the ransomware was created using a modified Hidden Tear code. Prior to this discovery, when the source code of Hidden Tear was made public for educational purposes, the creator was very specific about not using Hidden Tear as ransomware. Unfortunately, as expected, the following discovery of Ransom_CRYPTEAR.B and this current Pokemon-themed ransomware has shown that even with the best intentions, improper disclosure of sensitive information can lead to troublesome scenarios such as the mentioned discoveries.
To avoid ransomware, users are encouraged to regularly back up files and to have an updated security solution. Trend Micro solutions can protect users from the recent Pokemon Go ransomware. As the game is introduced in new regions, the Pokemon GO craze is expected to continue to gain momentum and cybercriminals will find ways to capitalize on it. In fact, in the month of July alone, malicious Pokemon Go apps were found tricking users into downloading them. This should remind users to remain vigilant of threats that may ride along the popularity of such games.

Facebook Bug Bounty #33 - Bypass ID user to linked Phone Number Vulnerability
Vulnerability Laboratory ID (VL-ID):
Common Vulnerability Scoring System:
Product & Service Introduction:
Facebook is a for-profit corporation and online social networking service based in Menlo Park, California, United States. The Facebook website was
launched on February 4, 2004 by Mark Zuckerberg, along with fellow Harvard College students and roommates, Eduardo Saverin, Andrew McCollum, Dustin
Moskovitz, and Chris Hughes. The founders had initially limited the website's membership to Harvard students; however, later they expanded it to
higher education institutions in the Boston area, the Ivy League schools, and Stanford University. Facebook gradually added support for students
at various other universities, and eventually to high school students as well. Since 2006, anyone age 13 and older has been allowed to become a
registered user of Facebook, though variations exist in the minimum age requirement, depending on applicable local laws. The Facebook name comes
from the face book directories often given to United States university students. After registering to use the site, users can create a user profile,
add other users as `friends`, exchange messages, post status updates and photos, share videos, use various applications (apps), and receive
notifications when others update their profiles. Additionally, users may join common-interest user groups organized by workplace, school, or other
topics, and categorize their friends into lists such as `People From Work` or `Close Friends`. In groups, editors can pin posts to top. Additionally,
users can complain about or block unpleasant people. Because of the large volume of data that users submit to the service, Facebook has come under
scrutiny for their privacy policies. Facebook, Inc. held its initial public offering (IPO) in February 2012, and began selling stock to the public
three months later, reaching an original peak market capitalization of $104 billion. On July 13, 2015, Facebook became the fastest company in the
Standard & Poor's 500 Index to reach a market cap of $250 billion. Facebook has more than 1.65 billion monthly active users as of March 31, 2016.

Check Point, azienda israeliana specializzata in prodotti relativi alla sicurezza, è venuta a conoscenza di quattro nuove vulnerabilità Android.
In occasione della Def Con 24, una tra le più importanti conferenze sulla sicurezza informatica, tenutasi a Las Vegas, il ricercatore di Check Point, Adam Donenfeld, ha parlato di un nuovo set di falle che affliggerebbe ben 900 milioni di device Android con a bordo chip Qualcomm. Tali vulnerabilità, rinominate “QuadRooter” dai ricercatori, permetterebbero l’accesso a dati sensibili, personali o aziendali. Le falle garantirebbero la possibilità di poter effettuare keylogging, di monitorare tramite GPS gli spostamenti del malcapitato e di registrare tracce video e audio.
I ricercatori a cui si deve la scoperta ammettono la difficoltà, per l’utente, di venire a conoscenza del problema. Infatti gli hacker potrebbero sfruttare la falla attraverso un app malevola, l’applicazione non avrebbe bisogno di particolari permessi per servirsi di queste vulnerabilità, essendo così difficilmente identificabile.
Essendo Qualcomm il primo costruttore a livello mondiale di chipset LTE, il problema è decisamente esteso. Dal canto suo, Qualcomm ha revisionato queste vulnerabilità, classificandole tutte come ad alto rischio, e ha rilasciato le patch agli OEM. Tra i dispositivi colpiti, si stima circa 900 milioni, figurano i modelli:
• Samsung Galaxy S7 & S7 Edge
• Sony Xperia Z Ultra
• Google Nexus 5X, 6 & 6P
• HTC One M9 & HTC 10
• LG G4, G5 & V10
• Motorola Moto X
• OnePlus One, 2 & 3
• BlackBerry Priv
• Blackphone 1 & 2
La buona notizia è che, a quanto sembra, per il momento nessun hacker avrebbe sfruttato la falla. In ogni caso, Check Point ha reso disponibile su Google Play l’app gratuita QuadRooter Scanner App. Questa individua la vulnerabilità QuadRooter, consente agli utenti Android discoprire se il loro dispositivo è soggetto a tale problema, e di scaricare le patch per risolverlo.
