High impact vulnerabilities in modern communication protocol used by mobile network operators (MNOs) can be exploited to intercept user data and carry out impersonation, fraud, and denial of service (DoS) attacks, cautions a newly published research. The findings are part of a new Vulnerabilities in LTE and 5G Networks 2020 report published by London-based cybersecurity firm Positive Technologies last week. "This paper encompasses the results of security assessments performed during the 2018–2019 timeframe on behalf of 28 telecom operators in Europe, Asia, Africa, and South America." Called the GPRS Tunnelling Protocol ( GTP ), the affected Internet Protocol (IP)-based communications standard defines a set of rules governing data traffic over 2G, 3G, and 4G networks. It also forms the basis for GPRS core network and its successor Evolved Packet Core ( EPC ), thus making it possible for users to keep connected to the Internet while moving from one place to the ot

Penetration tests have long been known as a critical security tool that exposes security weaknesses through simulated attacks on an organization's IT environments. These test results can help prioritize weaknesses, providing a road-map towards remediation. However, the results are also capable of doing even more. They identify and quantify security risk, and can be used as a keystone in cybersecurity policies. The same can be said about broader penetration testing practices. Organizations gain real value from learning about others' penetration testing experiences, trends, and the role they play in today's threat landscape. The world of pen testing can be an interesting balance of open collaboration and closely guarded privacy. While pen testers may engage in teaming exercises, or happily talk technique when they attend Black Hat, most organizations are extremely reluctant when it comes to discussing their pen testing practices and results. Of course, confidentia

Account takeover attacks have emerged as one of the most persistent and damaging threats to cloud-based SaaS environments. Yet despite significant investments in traditional security measures, many organizations continue to struggle with preventing these attacks. A new report, " Why Account Takeover Attacks Still Succeed, and Why the Browser is Your Secret Weapon in Stopping Them " argues that the browser is the primary battleground where account takeover attacks unfold and, thus, where they should be neutralized. The report also provides effective guidance for mitigating the account takeover risk.  Below are some of the key points raised in the report: The Role of the Browser in Account Takeovers According to the report, the SaaS kill chain takes advantage of the fundamental components that are contained within the browser. For account takeover, these include: Executed Web Pages - Attackers can create phishing login pages or use MiTM over legitimate web pages to harve

The recently disclosed FREAK (Factoring attack on RSA Export Keys) attack is an SSL/TLS vulnerability that is affecting major browsers, servers and even mobile devices.  FREAK vulnerability allows the attacker to intercept HTTPS connections between vulnerable clients and servers and force them to use weakened encryption, which the attacker can break to manipulate or steal sensitive data. Although most major hardware/software vendors and owners have patched this flaw, many are still susceptible to this kind of attack.  Instrumental in discovering FREAK flaw, the University of Michigan conducted scans and discovered that an estimated 36.7% of the 14 million websites offering browser-trusted certificates were vulnerable at the time of disclosure.  This includes some very high profile pages like nsa.gov, irs.gov and even the ubiquitous connect.facebook.com (the source of all Facebook "Like" buttons.)
