Okta Warns of Unprecedented Surge in Proxy-Driven Credential Stuffing Attacks

Okta Warns of Unprecedented Surge in Proxy-Driven Credential Stuffing Attacks
Apr 28, 2024 Credential Stuffing / Data Breach
Identity and access management (IAM) services provider Okta has warned of a spike in the "frequency and scale" of credential stuffing attacks aimed at online services. These unprecedented attacks, observed over the last month, are said to be facilitated by "the broad availability of residential proxy services, lists of previously stolen credentials ('combo lists'), and scripting tools," the company  said  in an alert published Saturday. The findings build on a  recent advisory  from Cisco, which cautioned of a global surge in brute-force attacks targeting various devices, including Virtual Private Network (VPN) services, web application authentication interfaces, and SSH services, since at least March 18, 2024. "These attacks all appear to be originating from TOR exit nodes and a range of other anonymizing tunnels and proxies," Talos noted at the time, adding targets of the attacks comprise VPN appliances from Cisco, Check Point, Fortinet, Soni

Massive Sign1 Campaign Infects 39,000+ WordPress Sites with Scam Redirects

Massive Sign1 Campaign Infects 39,000+ WordPress Sites with Scam Redirects
Mar 22, 2024 Web Security / Vulnerability
A massive malware campaign dubbed  Sign1  has compromised over 39,000 WordPress sites in the last six months, using malicious JavaScript injections to redirect users to scam sites. The most recent variant of the malware is estimated to have infected no less than 2,500 sites over the past two months alone, Sucuri said in a report published this week. The attacks entail injecting rogue JavaScript into legitimate HTML widgets and plugins that allow for arbitrary JavaScript and other code to be inserted, providing attackers with an opportunity to add their malicious code. The XOR-encoded JavaScript code is subsequently decoded and used to execute a JavaScript file hosted on a remote server, which ultimately facilitates redirects to a  VexTrio -operated traffic distribution system (TDS) but only if certain criteria are met. What's more, the malware uses time-based randomization to fetch dynamic URLs that change every 10 minutes to get around blocklists. These domains are registere

Hacked WordPress Sites Abusing Visitors' Browsers for Distributed Brute-Force Attacks

Hacked WordPress Sites Abusing Visitors' Browsers for Distributed Brute-Force Attacks
Mar 07, 2024 Vulnerability / Web Security
Threat actors are conducting brute-force attacks against WordPress sites by leveraging malicious JavaScript injections, new findings from Sucuri reveal. The attacks, which take the form of distributed brute-force attacks, "target WordPress websites from the browsers of completely innocent and unsuspecting site visitors," security researcher Denis Sinegubko  said . The activity is part of a  previously documented attack wave  in which compromised WordPress sites were used to inject crypto drainers such as Angel Drainer directly or redirect site visitors to Web3 phishing sites containing drainer malware. The latest iteration is notable for the fact that the injections – found on  over 700 sites  to date – don't load a drainer but rather use a list of common and leaked passwords to brute-force other WordPress sites. The attack unfolds over five stages, enabling a threat actor to take advantage of already compromised websites to launch distributed brute-force attacks against other po

Five Eyes Agencies Expose APT29's Evolving Cloud Attack Tactics

Five Eyes Agencies Expose APT29's Evolving Cloud Attack Tactics
Feb 27, 2024 Cloud Security / Threat Intelligence
Cybersecurity and intelligence agencies from the Five Eyes nations have released a joint advisory detailing the evolving tactics of the Russian state-sponsored threat actor known as  APT29 . The hacking outfit, also known as BlueBravo, Cloaked Ursa, Cozy Bear, Midnight Blizzard (formerly Nobelium), and The Dukes, is assessed to be affiliated with the Foreign Intelligence Service (SVR) of the Russian Federation. Previously attributed to the  supply chain compromise  of SolarWinds software, the cyber espionage group  attracted attention  in recent months for targeting Microsoft, Hewlett Packard Enterprise (HPE), and other organizations with an aim to further their strategic objectives. "As organizations continue to modernize their systems and move to cloud-based infrastructure, the SVR has adapted to these changes in the operating environment," according to the  security bulletin . These include - Obtaining access to cloud infrastructure via service and dormant accounts

New BLUFFS Bluetooth Attack Expose Devices to Adversary-in-the-Middle Attacks

New BLUFFS Bluetooth Attack Expose Devices to Adversary-in-the-Middle Attacks
Dec 04, 2023 Encryption / Technology
New research has unearthed multiple novel attacks that break Bluetooth Classic's forward secrecy and future secrecy guarantees, resulting in adversary-in-the-middle (AitM) scenarios between two already connected peers. The issues, collectively named  BLUFFS , impact Bluetooth Core Specification 4.2 through 5.4. They are tracked under the identifier  CVE-2023-24023  (CVSS score: 6.8) and were responsibly disclosed in October 2022. The attacks "enable device impersonation and machine-in-the-middle across sessions by only compromising one session key," EURECOM researcher Daniele Antonioli said in a study published late last month. This is made possible by leveraging two new flaws in the Bluetooth standard's session key derivation mechanism that allow the derivation of the same key across sessions. While forward secrecy in key-agreement cryptographic protocols ensures that past communications are not revealed, even if the private keys to a particular exchange are re

New P2PInfect Botnet MIPS Variant Targeting Routers and IoT Devices

New P2PInfect Botnet MIPS Variant Targeting Routers and IoT Devices
Dec 04, 2023 Malware / Botnet
Cybersecurity researchers have discovered a new variant of an emerging botnet called  P2PInfect  that's capable of targeting routers and IoT devices. The latest version, per Cado Security Labs, is compiled for Microprocessor without Interlocked Pipelined Stages ( MIPS ) architecture, broadening its capabilities and reach. "It's highly likely that by targeting MIPS, the P2PInfect developers intend to infect routers and IoT devices with the malware," security researcher Matt Muir  said  in a report shared with The Hacker News. P2PInfect, a Rust-based malware, was  first   disclosed  back in July 2023, targeting unpatched Redis instances by exploiting a critical Lua sandbox escape vulnerability ( CVE-2022-0543 , CVSS score: 10.0) for initial access. A subsequent analysis from the cloud security firm in September  revealed  a surge in P2PInfect activity, coinciding with the release of iterative variants of the malware. The new artifacts, besides attempting to condu

Randstorm Exploit: Bitcoin Wallets Created b/w 2011-2015 Vulnerable to Hacking
Nov 20, 2023 Cryptocurrency / Blockchain
Bitcoin wallets created between 2011 and 2015 are susceptible to a new kind of exploit called  Randstorm  that makes it possible to recover passwords and gain unauthorized access to a multitude of wallets spanning several blockchain platforms. "Randstorm() is a term we coined to describe a collection of bugs, design decisions, and API changes that, when brought in contact with each other, combine to dramatically reduce the quality of random numbers produced by web browsers of a certain era (2011-2015)," Unciphered  disclosed  in a report published last week. It's estimated that approximately 1.4 million bitcoins are parked in wallets that were generated with potentially weak cryptographic keys. Customers can check whether their wallets are vulnerable at www.keybleed[.]com. The cryptocurrency recovery company said it re-discovered the problem in January 2022 while it was  working for an unnamed customer  who had been locked out of its Blockchain.com wallet. The issue
