Session Hijacking 2.0 — The Latest Way That Attackers are Bypassing MFA

Session Hijacking 2.0 — The Latest Way That Attackers are Bypassing MFA

Sep 30, 2024 Identity Theft / Phishing Attack
Attackers are increasingly turning to session hijacking to get around widespread MFA adoption. The data supports this , as: 147,000 token replay attacks were detected by Microsoft in 2023, a 111% increase year-over-year (Microsoft).  Attacks on session cookies now happen in the same order of magnitude as password-based attacks (Google). But session hijacking isn't a new technique – so what's changed? Session hijacking has a new look When we think of the classic example of session hijacking, we think of old-school Man-in-the-Middle (MitM) attacks that involved snooping on unsecured local network traffic to capture credentials or, more commonly, financial details like credit card data. Or, by conducting client-side attacks compromising a webpage, running malicious JavaScript and using cross-site scripting (XSS) to steal the victim's session ID.  Session hijacking looks quite different these days. No longer network-based, modern session hijacking is an identity-based att...

Beyond Compliance: The Advantage of Year-Round Network Pen Testing

Beyond Compliance: The Advantage of Year-Round Network Pen Testing

Nov 18, 2024Penetration Testing / Network Security
IT leaders know the drill—regulators and cyber insurers demand regular network penetration testing to keep the bad guys out. But here's the thing: hackers don't wait around for compliance schedules. Most companies approach network penetration testing on a set schedule, with the most common frequency being twice a year (29%), followed by three to four times per year (23%) and once per year (20%), according to the Kaseya Cybersecurity Survey Report 2024 . Compliance-focused testing can catch vulnerabilities that exist at the exact time of testing, but it's not enough to stay ahead of attackers in a meaningful way. Why More Frequent Testing Makes Sense When companies test more often, they're not just checking a box for compliance—they're actually protecting their networks. The Kaseya survey also points out that the top drivers for network penetration testing are: Cybersecurity Control and Validation (34%) – ensuring the security controls work and vulnerabilities are minimized. Re...

Warning: Markopolo's Scam Targeting Crypto Users via Fake Meeting Software

Jun 19, 2024 Cybercrime / Cryptocurrency
A threat actor who goes by alias markopolo has been identified as behind a large-scale cross-platform scam that targets digital currency users on social media with information stealer malware and carries out cryptocurrency theft. The attack chains involve the use of a purported virtual meeting software named Vortax (and 23 other apps) that are used as a conduit to deliver Rhadamanthys , StealC , and Atomic macOS Stealer (AMOS), Recorded Future's Insikt Group said in an analysis published this week. "This campaign, primarily targeting cryptocurrency users, marks a significant rise in macOS security threats and reveals an expansive network of malicious applications," the cybersecurity company noted , describing markopolo as "agile, adaptable, and versatile." There is evidence connecting the Vortax campaign to prior activity that leveraged trap phishing techniques to target macOS and Windows users via Web3 gaming lures. A crucial aspect of the malicious o...

New RedLine Stealer Variant Disguised as Game Cheats Using Lua Bytecode for Stealth

New RedLine Stealer Variant Disguised as Game Cheats Using Lua Bytecode for Stealth

Apr 21, 2024 Malware / Cryptocurrency
A new information stealer has been found leveraging Lua bytecode for added stealth and sophistication, findings from McAfee Labs reveal. The cybersecurity firm has assessed it to be a variant of a known malware called RedLine Stealer owing to the fact that the command-and-control (C2) server  IP address  has been previously identified as associated with the malware. RedLine Stealer,  first documented  in March 2020, is typically delivered via email and malvertising campaigns, either directly or via  exploit kits  and loader malware like  dotRunpeX  and  HijackLoader . The off-the-shelf malware is capable of harvesting information from cryptocurrency wallets, VPN software, and web browsers, such as saved credentials, autocomplete data, credit card information, and geolocations based on the victims' IP addresses. Over the years, RedLine Stealer has been co-opted by several threat actors into their attack chains, making it a prevalent strai...

Orange Spain Faces BGP Traffic Hijack After RIPE Account Hacked by Malware

Jan 05, 2024 Network Security / Malware
Mobile network operator Orange Spain suffered an internet outage for several hours on January 3 after a threat actor used administrator credentials captured by means of stealer malware to hijack the border gateway protocol ( BGP ) traffic. "The Orange account in the IP network coordination center (RIPE) has suffered improper access that has affected the browsing of some of our customers," the company  said  in a message posted on X (formerly Twitter). However, the company emphasized no personal data was compromised and that the incident only affected some browsing services. The threat actor, who goes by the name Ms_Snow_OwO on X,  claimed  to have gained access to Orange Spain's RIPE account. RIPE is a regional Internet registry ( RIR ) that oversees the allocation and registration of IP addresses and autonomous system (AS) numbers in Europe, Central Asia, Russia, and West Asia. "Using the stolen account, the threat actor modified the AS number belonging to Ora...
