Android Tapsnake ??????????: ?????????????????

      No Comments on Android Tapsnake ??????????: ?????????????????

最近、デバイスが「Trojan: MobileOS/Tapsnake」という脅威に感染していると思い込ませてユーザーを脅そうとする一連のモバイル広告が確認されています。

図 1. Tapsnake への感染を通知する偽の警告
 

このマルウェア感染警告は偽物です。Tapsnake は Android を狙う比較的古い脅威(シマンテックでは 2010 年にブログでこの脅威について報告しており、Android.Tapsnake として検出します)で、この種の広告の信憑性を高めるために、広告の中でたまたま名前が使われているだけです。シマンテックでは、新品の Android デバイスを使って、この広告を提供するサイトにアクセスしてみました。このデバイスは初期インストールの状態で、他に何も追加されていませんでしたが、それでもこの警告が表示されました。この脅威は iOS デバイスを標的にはしていませんが、Apple 社の iPhone ユーザーからも Tapsnake 警告が表示されたという報告があります

この種の警告はたいてい、元々 PC を狙っていたスケアウェアに関連しています。スケアウェアの Web サイトにアクセスすると、コンピュータやデバイスがマルウェアに感染しているという警告が表示されます。このようなスケアウェアサイトが、偽のウイルス対策ソフトウェアの無料ダウンロードを提供している場合もあります。

これはすべて、ユーザーにアプリをダウンロードさせるための策略です。

信頼できるアプリストア以外からアプリをインストールしないようにしてください。また、Google Play アプリストアで提供されているノートン モバイルセキュリティなど、有名なセキュリティソフトウェアだけを信頼してください。スマートフォンやタブレットの安全性に関する一般的なヒントについては、モバイルセキュリティの Web サイト(英語)を参照してください。

????? ??????? ???????????? ???????????? AVAST ? ???? ????: ????????? ?????? ? ?????????????

Год назад, накануне нового года, было зафиксировано более 17 миллионов мобильных устройств подсоединившихся к Интернету. Еще не была снята защитная пленка с экрана подаренного сматрфона, а подарочная упаковка выброшена, как хакеры начали разрабатывать новые варианты мобильных вирусов. В первой половине этого года, по сообщению экспертов по компьютерной безопасности, атаке подверглись 79% мобильных устройств с операционной […]

Android Tapsnake Mobile Scareware: Ads Push Antivirus

Recently we have observed a series of mobile ads intended to scare users into believing that their device is infected with a threat called “Trojan: MobileOS/Tapsnake”.

Figure 1. Fake Tapsnake infection warnings
 

The malware alert is fake. Tapsnake is an older Android threat (we blogged about it in 2010 and detect it as Android.Tapsnake) that just happens to be mentioned in these ads to make them appear more authentic. We visited a site serving these ads using a brand new Android device with a fresh install and nothing on it and still received this alert. Users of Apple’s iPhone have also reported seeing Tapsnake alerts, despite the fact that the threat doesn’t target iOS devices.

Figure 2. Scareware tactics target Android users
 

This type of warning is commonly associated with scareware, which originated on PCs. When users visit scareware websites, they are shown a warning that claims their computer or device is infected with malware. These scareware sites may then offer free downloads of fake antivirus software.

This is all a trick designed to convince the user to download an application.

Symantec Security Response advises users not to install applications outside of trusted app stores. Instead, users should only trust well-known and reputable security software, such as Norton Mobile Security available on the Google Play app store.
