Intel Security released its McAfee Labs Threats Report: February 2015, including assessments of the mobile threat landscape and the failure of mobile app developers to patch critical Secure Sockets Layer [SSL] vulnerabilities, potentially impacting millions of mobile phone users. McAfee Labs also revealed details on the increasingly popular Angler exploit kit, and warned of increasingly aggressive Potentially Unwanted Programs [PUP’s] that change system settings & gather personal information without the knowledge of users.
McAfee Labs researchers found that mobile app providers have been slow to address the most basic SSL vulnerabilities: Improper digital certificate chain validation. In September 2014, the Computer Emergency Response Team [CERT] at Carnegie Mellon University released a list of mobile apps possessing this weakness, including apps with millions of downloads to their credit.
In January, McAfee Labs tested the 25 most popular apps on CERT’s list of vulnerable mobile apps that send login credentials through insecure connections and found that 18 still have not been patched despite public disclosure, vendor notification, and, in some cases, multiple version updates addressing concerns other than security. McAfee Labs researchers simulated man-in-the-middle (MITM) attacks that successfully intercepted information shared during supposedly secure SSL sessions. The vulnerable data included usernames and passwords and in some instances, login credentials from social networks and other third party services.
Although there is no evidence that these mobile apps have been exploited, the cumulative number of downloads for these apps ranges into the hundreds of millions. Given these numbers, McAfee Labs’ findings suggest that the choice by mobile app developers to not patch the SSL vulnerabilities has potentially put millions of users at risk of becoming targets of MITM attacks.
This crimeware package contains easy-to-use attack features and new capabilities such as file-less infection, virtual machine and security product evasion, and the ability to deliver a wide range of payloads including banking Trojans, rootkits, ransomware, CryptoLocker & backdoor Trojans.
Some of the highlights of the report are below:
Mobile Malware
McAfee Labs reported that mobile malware samples grew 14 percent during the fourth quarter of 2014, with Asia and Africa registering the highest infection rates. At least 8 percent of all McAfee-monitored mobile systems reported an infection in Q4 2014, with much of the activity being attributed to the AirPush ad network.
Potentially Unwanted Programs
In Q4, McAfee Labs detected PUPs on 91 million systems each day. McAfee Labs sees PUPs becoming more and more aggressive, posing as legitimate apps while performing unauthorized actions such as displaying unintended ads, modifying browser settings, or collecting user and system data.
Ransomware
Beginning in Q3, the number of new ransomware samples began to grow again after a four-quarter decline. In Q4, the number of new samples grew 155 percent.
Signed Malware
After a brief drop in new malicious signed binaries, the pace of growth resumed in Q4 with a 17 percent increase in total signed binaries.
Total Malware
McAfee Labs now detects 387 new samples of malware every minute, or more than six every second.
