Cybersecurity researchers on Tuesday disclosed a now-patched security flaw in TikTok that could have potentially enabled an attacker to build a database of the app's users and their associated phone numbers for future malicious activity. Although this flaw only impacts those users who have linked a phone number with their account or logged in with a phone number, a successful exploitation of the vulnerability could have resulted in data leakage and privacy violation, Check Point Research said in an analysis shared with The Hacker News. TikTok has deployed a fix to address the shortcoming following responsible disclosure from Check Point researchers. The newly discovered bug resides in TikTok's " Find friends " feature that allows users to sync their contacts with the service to identify potential people to follow. The contacts are uploaded to TikTok via an HTTP request in the form of a list that consists of hashed contact names and the corresponding phone numbe...

Most companies with small security teams face the same issues. They have inadequate budgets, inadequate staff, and inadequate skills to face today's onslaught of sophisticated cyberthreats. Many of these companies turn to virtual CISOs (vCISOs) to provide security expertise and guidance. vCISOs are typically former CISOs with years of experience building and managing information security programs across large and small organizations. Autonomous XDR company Cynet, a provider of an automated breach protection platform and MDR service for even the smallest security teams, is conducting a webinar with well-known vCISO Brian Haugli to understand the common challenges faced by CISOs with small security teams [ register here ]. In the first part of the webinar, Haugli will share the four foundational risks that are common across most companies he helps. He will then discuss the most common pieces of advice he provides across the companies he serves. Haugli will also share a situation ...

Google on Monday disclosed details about an ongoing campaign carried out by a government-backed threat actor from North Korea that has targeted security researchers working on vulnerability research and development. The internet giant's Threat Analysis Group (TAG) said the adversary created a research blog and multiple profiles on various social media platforms such as Twitter, LinkedIn, Telegram, Discord, and Keybase in a bid to communicate with the researchers and build trust. The goal, it appears, is to steal exploits developed by the researchers for possibly undisclosed vulnerabilities, thereby allowing them to stage further attacks on vulnerable targets of their choice. "Their blog contains write-ups and analysis of vulnerabilities that have been publicly disclosed, including 'guest' posts from unwitting legitimate security researchers, likely in an attempt to build additional credibility with other security researchers,"  said  TAG researcher Adam Weide...

In 1982, when SMTP was first specified, it did not contain any mechanism for providing security at the transport level to secure communications between mail transfer agents. Later, in 1999, the STARTTLS command was added to SMTP that in turn supported the encryption of emails in between the servers, providing the ability to convert a non-secure connection into a secure one that is encrypted using TLS protocol. However, encryption is optional in SMTP, which implies that emails can be sent in plaintext.  Mail Transfer Agent-Strict Transport Security (MTA-STS)  is a relatively new standard that enables mail service providers the ability to enforce Transport Layer Security (TLS) to secure SMTP connections and to specify whether the sending SMTP servers should refuse to deliver emails to MX hosts that that does not offer TLS with a reliable server certificate. It has been proven to successfully mitigate TLS downgrade attacks and Man-in-the-Middle (MitM) attacks. SMTP TLS Report...

A newly discovered Android malware has been found to propagate itself through WhatsApp messages to other contacts in order to expand what appears to be an adware campaign. "This malware spreads via victim's WhatsApp by automatically replying to any received WhatsApp message notification with a link to [a] malicious Huawei Mobile app," ESET researcher Lukas Stefanko said. The link to the fake Huawei Mobile app, upon clicking, redirects users to a lookalike Google Play Store website. Once installed, the wormable app prompts victims to grant it notification access, which is then abused to carry out the wormable attack. Specifically, it leverages WhatApp's quick reply feature — which is used to respond to incoming messages directly from the notifications — to send out a reply to a received message automatically. Besides requesting permissions to read notifications, the app also requests intrusive access to run in the background as well as to draw over other apps, ...

Over the years,  penetration testing  has had to change and adapt alongside the IT environments and technology that need to be assessed. Broad cybersecurity issues often influence the strategy and growth of pen-testing. In such a fast-paced field, organizations get real value from learning about others' penetration testing experiences, identifying trends, and the role they play in today's threat landscape. While there is much to be gained from a single snapshot, additional value can come from long term data collection and year over year comparisons. We can see whether the effects that recent trends have on pen testing are long term, or simply a temporary shift, and how they affect the continuing evolution of penetration testing. For instance, 2020 saw a massive influx of remote work. Unfortunately, the convenience of working safely from home increased the risk of a breach as countless new attack vectors opened up, both from the way employees connected to networks, as well ...
