Android Simplelocker ransomware

A security firm says it has found the first confirmed case of ransomware that encrypts files held by Android devices.

Eset reports that the Trojan - called Simplelocker - targets SD cards slotted into tablets and handsets, electronically scrambling certain types of files on them before demanding cash to decrypt the data.

The message is in Russian, and payment is requested in Ukrainian currency.

Seorang pakar media mengatakan  the threat was noteworthy, but limited at this stage.

"File-encrypting malware has proved to be a lucrative criminal enterprise so it is unsurprising that Android has become a new target," said Dr Steven Murdoch, of the University of Cambridge's Computer Laboratory.

"Pengguna ponsel cerdas seyogyanya sangat berhati-hati dalam menginstal software dari sumber yang lain nya sources other than the operating system-provided application store, and should pressure their phone supplier to promptly provide security updates to defend against known vulnerabilities."


He noted that networks often lagged or failed altogether to provide Google's security patches for older Android handsets.

Mencegah Pornografi

Slovakia-based Eset mengatakan affected device owners were presented with a message saying bahwa ponsel mereka terkunci karena mereka melihat dan mengedarkan "pornografi anak , perjinahan hewan dan lain penyimpangan".

It goes on to instruct the victims to pay 260 hryvnias ($22, £13) via the Ukrainian MoneXy cash transfer system.

"After payment your device will be unlocked within 24 hours. In case of no PAYMENT YOU WILL LOSE ALL DATA ON your device!" it added.

Perusahaan Pengaman itu mengatakan bahwa tipe file itu dapatdienkripsi termasuk jpeg and gif images, dox and txt text files, and mkv, avi and mp4 media.

It added that information about the infected device would also be uploaded to the server computer used by the cyber-thieves, potentially to help them ensure the right data was decrypted when a payment was received.

This server was hosted on a hidden part of the internet called Tor, Eset added, making the scam hard to trace.

"Our analysis... revealed that we are most likely dealing with a proof-of-concept or a work in progress - for example, the implementation of the encryption doesn't come close to 'the infamous Cryptolocker' on Windows," wrote security researcher Robert Lipovsky.

"Nevertheless, the malware is fully capable of encrypting the user's files, which may be lost if the encryption key is not retrieved.

"Sementara malware mengandung fungsi untuk mendekrip file-file, kami sangat merekomendasikan against paying up - not only because that will only motivate other malware authors to meneruskan jenis operasi kotor ini, but also because there is no guarantee that the crook will keep their part of the deal and actually decrypt them."

Although this is the first reported instance of Android ransomware encrypting files, there have been other types.

Last month a security researcher known as Kafeine reported about a variant that prevented Android apps from launching, effectively making infected devices useless, unless a $300 payment was made.

Before that, the security firm Symantec reported about an app that caused pop-up warnings to repeatedly appear, which could not easily be closed unless a fee was paid.

Mengapa Orang Masih Menggunakan Lampu Pijar

dikutip dari Jolie Lee, USA TODAY


Pada tahun 2014, orang Amerika meninggalkan penggunaan lampu pijar standar.

Starting Jan. 1, the United States will no longer manufacture or import incandescent bulbs – walaupun toko-toko masih diijinkan menjual barang stalthough stores can still sell what they have in stock. The phaseout is a result of federal rules to switch to more energy-efficient bulbs.

Energy-efficient bulbs cost more than incandescent bulbs but last much longer and save on energy costs in the long-term. So why are people still buying incandescent bulbs and what will the phaseout mean for you?


Harga bola lampu pijar jauh lebih murah than their energy-efficient alternatives – mainly CFLs (compact fluorescent lamps) and LEDs (light emitting diodes).
