Our analysis of version 6.4.2 of the Android version shows that some of our reported issues have been partially resolved and some remain unresolved. The application collects and transmits personally identifiable data points in a manner that leaves this data vulnerable to surveillance by third parties. { bidder: 'openx', params: { unit: '539971080', delDomain: 'idm-d.openx.net' }}, On March 17, 2016, we sent a letter to Tencent with additional questions about the security vulnerabilities we identified. iasLog("exclusion label : wprod"); This analysis reveals that both versions of QQ Browser transmit a number of personally identifiable user data points either with no encryption or with easily decryptable encryption. The above RSA public key is only 128 bits, which is small enough to be easily factored. iasLog("criterion : cdo_ptl = entry-mcp"); var mapping_leftslot = googletag.sizeMapping().addSize([1063, 0], [[120, 600], [160, 600], [300, 600]]).addSize([963, 0], [[120, 600], [160, 600]]).addSize([0, 0], []).build(); (Encrypted WUP responses use MTEA+MCBC in both the Android and Windows versions. follow-up definition: 1. a further action connected with something that happened before: 2. a farther action connected…. googletag.pubads().setTargeting('cdo_alc_pr', pl_p.split(",")); bytes of Q-GUID and 2nd, 4th, 6th, etc. They justify the collection of hard drive serial numbers by saying that “Hard drive serial number is use for identifying independent user, so that QQ Browser can offer personalized service.” They then inquire as to where we will be releasing our published findings.

The International Mobile Equipment Identifier is a string of numbers that is unique for every device.

googletag.pubads().addEventListener('slotRenderEnded', function(event) { if (!event.isEmpty && event.slot.renderCallback) { event.slot.renderCallback(event); } }); QQ Browser is a web browser for the Android, Windows, OS X, and iOS platforms, developed by Tencent. } We found that all WUP requests sent by the Windows browser still use the same symmetric, easily decryptable algorithm. {code: 'ad_rightslot', pubstack: { adUnitName: 'cdo_rightslot', adUnitPath: '/2863368/rightslot' }, mediaTypes: { banner: { sizes: [[300, 250]] } }, { bidder: 'triplelift', params: { inventoryCode: 'Cambridge_SR' }}, Search for abbreviation meaning, word to abbreviate, or lists of abbreviations. Acronym Finder, All Rights Reserved. The Android version of QQ Browser, which used the asymmetric RSA algorithm, used a key size that was too small to be effective and did not meet the, recommended practice of using 2048 bit keys. { bidder: 'onemobile', params: { dcn: '8a969411017171829a5c82bb4deb000b', pos: 'cdo_rightslot_flex' }}, While the final text of the law appeared to back away from controversial requirements in earlier draft versions of the law, which required companies to provide backdoor access and submit encryption keys to authorities, the passed version of the law still requires companies to provide technical assistance and potentially decrypt user communications. Moreover, session keys are now sampled from the entire 128-bit AES keyspace instead of being restricted to certain ASCII digits. iasLog("criterion : cdo_l = en"); Unique identifier Windows randomly generates for each Windows user.

We inquire what steps will be taken to resolve the reported issues and what the timeline will be for their resolution. { bidder: 'pubmatic', params: { publisherId: '158679', adSlot: 'cdo_btmslot' }}]}]; Tencent reported that QQ had 853 million monthly active users (MAUs) in 2015, while WeChat/Weixin has 640 million MAUs during the same period. priceGranularity: customGranularity, This page is about the meanings of the acronym/abbreviation/shorthand WUP in the Internet field in general and in the Chat terminology in particular. { bidder: 'triplelift', params: { inventoryCode: 'Cambridge_HDX' }}, googletag.pubads().setTargeting("cdo_c", ["people_society_religion", "law_government_military"]); { bidder: 'ix', params: { siteId: '195467', size: [320, 50] }}, Alongside competitors such as UC Browser and Baidu Browser, QQ Browser is one of a number of third-party mobile browsers which are particularly popular in Asia. We were able to use Wolfram Alpha, an online mathematics engine, to factor the modulus in less than one second: *Wifi MAC address is encrypted with DES+ECB with key, Interestingly, this encryption process employed in QQ Browser utilizes the same non-standard MTEA+MCBC implementation we observed in our study of Baidu Browser. Add to My List bids: [{ bidder: 'rubicon', params: { accountId: '17282', siteId: '162036', zoneId: '776140', position: 'atf' }}, NASA, Android does not allow an APK to upgrade an app if the APK is signed with a different digital signature than that of the currently installed app, and so this attack cannot be used to replace QQ browser with an arbitrary APK; however, it may still be used to install a new app, and a properly crafted APK using the name and logo of QQ browser could be used to deceive a user into installing a malicious APK (see Figure 2). { bidder: 'ix', params: { siteId: '195465', size: [300, 250] }}, However, we found two attacks against the update process that any man-in-the-middle performing an active attack could still utilize to remotely run code on a QQ Browser user’s machine. },{ Alongside competitors such as UC Browser and Baidu Browser, QQ Browser is one of a number of third-party mobile browsers which are, . { bidder: 'pubmatic', params: { publisherId: '158679', adSlot: 'cdo_rightslot' }}]}, { bidder: 'sovrn', params: { tagid: '346693' }}, }, WUP responses were not encrypted using the asymmetric algorithm described earlier but instead used a purely symmetric algorithm, and thus we were not required to factor any key. {code: 'ad_btmslot_a', pubstack: { adUnitName: 'cdo_btmslot', adUnitPath: '/2863368/btmslot' }, mediaTypes: { banner: { sizes: [[300, 250]] } }, { bidder: 'onemobile', params: { dcn: '8a969411017171829a5c82bb4deb000b', pos: 'cdo_topslot_728x90' }}, googletag.pubads().setTargeting("cdo_tc", "resp"); The application offers a number of features beyond those offered by built-in browsers, such as tabbed windows and integration with other chat platforms. int j = 10000000 + new Random().nextInt(89999999); The collection of such fine-grained information about a user, a user’s device, and a user’s online behavior (and its insecure transmission) would be especially concerning for high-risk users, which in China could include democracy activists, journalists, human rights advocates, lawyers, and others. The coronavirus pandemic is a global phenomenon, but different countries have adopted different responses to it according to their local circumstances and traditions. var mapping_topslot_a = googletag.sizeMapping().addSize([746, 0], []).addSize([0, 550], [[300, 250]]).addSize([0, 0], [[300, 50], [320, 50], [320, 100]]).build(); The Q-UA and Q-UA2 values include hard-coded information about the version of QQ browser installed and the type of hardware on which it is installed. { bidder: 'pubmatic', params: { publisherId: '158679', adSlot: 'cdo_topslot' }}]}, { bidder: 'ix', params: { siteId: '195451', size: [300, 50] }}, googletag.pubads().setTargeting("cdo_dc", "english"); Abbreviations.com. { bidder: 'criteo', params: { networkId: 7100, publisherSubId: 'cdo_btmslot' }}, As of the date of publication, we have not received a reply.

We have also published a primer on mobile security and privacy, entitled The Many Identifiers in Our Pockets, which provides further background on the types of personal data commonly collected and transmitted by mobile devices. Since MTEA+MCBC is purely symmetric, any man-in-the-middle observing traffic can use the hard-coded encryption key to easily decrypt all encrypted WUP requests. The letter is reproduced, Our analysis of version 9.3.6872 of the Windows version shows that some of the issues we reported have been resolved and some remain unresolved. { bidder: 'appnexus', params: { placementId: '11654174' }},
