Last week in security news, researchers spotted 15 adware-laden Android apps lurking on the Google Play store that hid their icons after users installed them. Analysts also detected several phishing campaigns, including one that used certified email to deliver malware. Finally, news emerged of a city in Georgia that avoided data loss after suffering its third ransomware attack this year.

Top Story of the Week: Sneaky Android Adware on the Google Play Store

Security researchers at SophosLabs discovered 15 apps that had a combined total of 1.3 million downloads from Android users. After successful installation, each of these apps displayed a fake error message and redirected users to Google Maps to trick them into thinking there was a problem with installation. The app then hid its own icon to establish persistence on the infected device so it could begin aggressively serving up ads.

SophosLabs notified Google about these malicious programs back in July 2019. According to the security firm’s research, Google’s teams responded by removing the apps from Google Play.

Security Tip of the Week: Strengthen Your Mobile Security Posture

Defense against adware-laden apps and other mobile threats should start with a unified endpoint management (UEM) solution. This tool should be capable of analyzing how mobile devices and other IT assets interact with the network. Security personnel can then use the solution to respond to any malicious activity that’s observed.

While searching for a UEM platform, infosec professionals should ideally choose technology that uses artificial intelligence (AI) to correlate information about a potential threat, as such capabilities will help empower them to make better, more informed decisions about their systems’ security.

Did Brazil DSL Modem Attacks Change Device Security?

From 2011 to 2012, millions of Internet users in Brazil fell victim to a massive attack against vulnerable DSL modems. By configuring the modems remotely, attackers could redirect users to malicious domain name system (DNS) servers. Victims trying to visit popular websites (Google, Facebook) were instead directed to imposter sites. These rogue sites then installed malware on victims' computers.According to a report from Kaspersky Lab Expert Fabio Assolini citing statistics from Brazil's Computer Emergency Response Team, the attack ultimately infected…

Who Carries the Weight of a Cyberattack?

Almost immediately after a company discovers a data breach, the finger-pointing begins. Who is to blame? Most often, it is the chief information security officer (CISO) or chief security officer (CSO) because protecting the network infrastructure is their job. Heck, it is even in their job title: they are the security officer. Security is their responsibility. But is that fair – or even right? After all, the most common sources of data breaches and other cyber incidents are situations caused…

Transitioning to Quantum-Safe Encryption

With their vast increase in computing power, quantum computers promise to revolutionize many fields. Artificial intelligence, medicine and space exploration all benefit from this technological leap — but that power is also a double-edged sword. The risk is that threat actors could abuse quantum computers to break the key cryptographic algorithms we depend upon for the safety of our digital world. This poses a threat to a wide range of critical areas. Fortunately, alternate cryptographic algorithms that are safe against…

Securing Your SAP Environments: Going Beyond Access Control

Many large businesses run SAP to manage their business operations and their customer relations.
