Android is becoming Windows

Android Malware

• Amount of malware continues to grow• Can be deployed by Windows malware (q.v.)• Reports of smartphones & tablets shipping

with pre-installed malware• Everything old is new again: – first worm discovered, Android/Samsapo– first ransomware discovered, Android/Simplocker

• On the plus side– Google plans to periodically re-scan installed apps–Most malware originates outside of Google Play,

device or carrier stores

Android Malware

Have you seen any malware, potentially unwanted applications or junk apps on your Android devices?

Yes

no

Banking bots & Bitcoin thieves

• Arrival of *coin mining and stealing on multiple platforms, technologies (Android, BAT, MSIL, Win32, VBS)

• Win32/Corkow banking Trojan targets Bitcoin wallets, Android developers and Russian business bank accounts

• Win32/Qadars banking bot now drops Android iBanking component Android/Spy.Agent.AF via Facebook webinject

Heartbleed SSL Vulnerability

• 2 year old flaw in OpenSSL allows eavesdropping into communications

• About two-thirds of web sites were affected• Also affected networking gear from Cisco,

Juniper and others; in VPN software, etc.• Windows 8 inbox VPN clients, too• May have been exploited for those 2 years

before being discovered

Internet of Things

• Smart TVs – “Red Button” bot in your living room? – Script injection, credential theft, malware?– all via broadcast (EU standard, soon in US)

• Smart TVs – the spy in your living room?– Some have microphones and webcams

• Not apparent when they’re on; or how to turn off (or if)• Can be remotely taken over (Samsung)

– Sent viewing habits, URLs, filenames of private videos (LG)

– Replace images/videos on screen (Philips)

• Tesla’s iPhone app, used to lock/unlock vehicle, vulnerable to brute-forcing

Infected

^

IOiT: Routers and DVRs, etc.

• Residential gateway broadband routers under attack from worms like Win32/RBrute– DNS changing

• Browser injection– Ad injection substitution, spying, etc.

• Credential theft– bank fraud, shopping, social media, webmail …

• Search engine redirection– Bing, Google, Yahoo redirect to sponsored & PPC searches

– coin mining (DVR, NAS...)• Nowhere near as effective as PCs, but remember:

“Quantity has a quality all its own.” – Joseph Stalin

IOiT: Routers and DVRs, etc.
