Watch out, Ransomware DoubleLocker Incar Android

Researchers from the ESET security company found a ransomware that attacked the Android operating system. In addition to holding user data, a ransomware called DoubleLocker can change the device PIN.

"Changing the PIN and preventing users from accessing the device and encrypting the victim data," says researchers from ESET Lukáš Štefanko.

Just like other ransomware, the victim must grant the ransom that the hacker requested to retrieve the data.

The previous DoubleLock method is also used (malware) in the banking section. Even so, ransomware is not able to access banking services from Android-based smartphones or tablets.

DoubleLocker spreads through a fake version of Adobe Flash Player updates that are posted on certain sites. Ransomware is pretty clever. He can "seduce" the victim to activate DoubleLocker unknowingly.

Once active, ransomware will encrypt the data that is on Android smartphones. Smartphone can not be opened because protected new PIN.

WhatsApp App will Have Live Location Feature

WhatsApp users can finally share their movements in real-time in WhatsApp applications. Dubbed Live Location, this new feature lets users track contacts for 30 minutes, an hour or eight hours at a time.

Previously, WhatsApp allowed users to share their location on the map regularly. Now, users can choose Live Locations so friends can see their location on the map, which automatically updates as they move.

WhatsApp says its new feature is a simple and safe way to let people know where you are. The end-to-end location is encrypted - like messages, photos, videos and files you send in WhatsApp, which should remove some users' fears about this feature.

You can also choose to end location sharing before the end of the specified time period. WhatsApp imagines Live Location used by people trying to meet with friends, letting loved ones know they are safe or sharing trips.

How To "Crack" Break Through Security Almost All WiFi in the World

The tech world was struck by the invention of Mathy Vanhoef. The Belgian security researcher from Katholieke Universiteit Leuven last weekend publicized the findings of a security hole that could break into a Wi-Fi wireless internet network, although it protected the W-Fi Protected Access II (WPA2) security protocol.

Named the key re-installation attack aka "Krack", this security gap can be used to tap various kinds of information sent by the client device to the internet via Wi-Fi network.

"This can be used to steal sensitive data such as credit card numbers, passwords, chat messages, emails, photos, and more," said researcher Mathy Vanhoef in the site devoted to the source of information about Kracks.

The Krack impact scale is enormous, as it includes all electronic devices that have Wi-Fi capability with WPA2. The number of millions, if not billions, ranging from handheld devices, computers, to a smart refrigerator.

"This weakness exists in the WI-Fi standard itself, not in specific products or implementations individually, so any WPA2 implementation must be affected," Vanhoef continued.
