Declaring machine war against malicious Android packages

Do you know the notion “machine war”? If you’re a fan of the Matrix movie trilogy then probably, yes. It denotes the fictional rise of artificially intelligent machines against the human race and their violent conquest of human beings. We want to apply a similar dominance of computationally powerful machines, not to create a population of slaves, but against numerous malicious Android packages that wildly proliferate on unofficial markets.

The idea of malware detection with no human interaction appeared earlier on our blog. In a fundamental article about AVAST research activities by AVAST’s COO, Ondřej Vlček, he effectively described the technologies we employ to deal with Windows threats. Two techniques have been mentioned explicitly, Malware Similarity Search and Evo-Gen, both working with Windows PE file format. Sometimes the latter form of detection technique is denoted as weak automated anti-malware heuristic.

The main effort is to reach two slightly conflicting qualities at the same time: The robustness, which means that suggested methods cover as many threats as possible; and simplicity, so that the methods are easily implemented in AVAST’s mobile security solution. The search for balance between those qualities is assisted by lessons learned from automated heuristic for Windows PE executables.

The name “Antivirus” became popular over a decade ago, when computer viruses were making headlines and being featured on nightly news broadcasts. Consumers became aware of the term, therefore marketers adopted it to describe the protection security software offered.

“Today viruses are the minority when it comes to malware,” explains Jiri Sejtko, Director of the AVAST Virus Lab. “More common than viruses is malware like Trojans, Worms, Backdoors, Exploits, Adware, and PUP (Potentially Unwanted Programs), which can include communication clients, remote desktops and password revealers, just to name a few.”

Cybercrooks are driving the change. Back in the day, it was enough for a hacker to have his ego stroked by playing practical jokes, but the diversity of the early market and platforms kept early viruses from spreading far and wide.

“The focus of online criminals has shifted and therefore malware has changed, “ said Sejtko. Read more…
