With phishing, hackers attempt to steal valuable information by impersonating a trusted source. Phishing schemes can come in several different forms, including phone calls, fake websites and sales emails.
Accidentally downloading malware or spyware can enable hackers to access information stored on your computer, including credit card information and other details. Malware may include a keylogger that records your keystrokes or browser history and then sends that information to a hacker.
High-profile data breaches -- the ones we hear about -- have, unfortunately, become fairly common over the last few years. And with the amount of data stored online, it represents another avenue for hackers to steal credit card, financial and other kinds of personal information. According to Statista, the 1,473 data breaches in the U.S. in 2019 led to the exposure of nearly 165 million personal data records, a trend that showed no signs of slowing down in 2020.
Unsecured public Wi-Fi networks carry some danger if you enter sensitive information when connected to them. While airport or hotel Wi-Fi can be convenient, precautions should be taken to protect against losing credit card and other sensitive information. Furthermore, should "Free Public Wi-Fi" show up on your device, it may actually be a hacker on a nearby smartphone or laptop attempting to get unsuspecting users to sign on so they can steal your personal information.
If you're connecting to any public networks, it's helpful to use a VPN to protect yourself from malware and hackers. Not to mention, antivirus software can protect you if you accidentally download harmful malware.
It can be tempting to save your credit card information on Google or at e-commerce sites you frequent. However, you should consider avoiding this practice, as it potentially provides hackers with access to your personal information in the case of a data breach.
Between data breaches, malware and public Wi-Fi networks, hackers can use several online methods to steal your credit card and personal information. Updating your passwords on any websites you regularly visit can prevent them from gaining access to this data.
Credit cards are a common target for cybercriminals, and that's not going to change anytime soon. Being aware of the methods they use to steal personal information -- credit card data, in particular, but also other details that can lead to, among other things, identify theft -- is the first step toward protecting yourself.
Extracting and later resealing the chip takes about four hours. It takes another six hours to take measurements for each account the attacker wants to hack. In other words, the process would take 10 hours to clone the key for a single account, 16 hours to clone a key for two accounts, and 22 hours for three accounts.
By observing the local electromagnetic radiations as the chip generates the digital signatures, the researchers exploit a side channel vulnerability in the NXP chip. The exploit allows an attacker to obtain the long-term elliptic curve digital signal algorithm private key designated for a given account. With the crypto key in hand, the attacker can then create her own key, which will work for each account she targeted.
The Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday warned U.S. organizations that hackers are now targeting Internet-connected uninterruptable power supply (UPS) devices. Such attacks can literally fry PCs, or at least their power supplies, but the more dangerous outcome is that they can cause fires in datacenters, homes, and offices.There are many different UPS offerings these days that connect to the internet to enable remote management, maintenance, and monitoring. But while these capabilities are designed to make UPS for datacenters, industrial facilities, hospitals, offices, and homes more reliable, internet connectivity also makes them a target for hackers according to CISA, reports BleepingComputer."The Cybersecurity and Infrastructure Security Agency (CISA) and the Department of Energy are aware of threat actors gaining access to a variety of internet-connected uninterruptible power supply (UPS) devices, often through unchanged default usernames and passwords," a statement by CISA reads. "Organizations can mitigate attacks against their UPS devices, which provide emergency power in a variety of applications when normal power sources are lost, by removing management interfaces from the internet."In a bid to avoid attacks on mission critical machines, CISA recommends organizations ensure that their UPS are not reachable via the internet. Since this is sometimes impossible to do, CISA also recommends using strong passwords or passphrases, enabling multifactor authentication where available, implementing login timeout/lockout policies, and hiding any UPS devices behind virtual private networks. Obviously, default or weak passwords should not be used.Perhaps the biggest problem is that UPS devices are, like other internet-connected devices, fundamentally vulnerable. For example, UPS solutions from APC suffered from a zero-day exposure called TLStorm that can be used remotely by unauthenticated perpetrators.It should be noted that targeting Internet-connected UPS devices does not necessarily bring benefits to attackers. Uninterruptible power supplies do not host mission critical or financial data, so there is nothing to steal. But downing crucial datacenters or mission critical servers poses dangers to businesses or even states, which is why protecting UPS devices from cyberattacks is important.
A sophisticated Chinese advanced persistent threat (APT) actor exploited a critical security vulnerability in Sophos' firewall product that came to light earlier this year to infiltrate an unnamed South Asian target as part of a highly-targeted attack.
The cybersecurity firm, which issued a patch for the flaw on March 25, 2022, noted that it was abused to "target a small set of specific organizations primarily in the South Asia region" and that it had notified the affected entities directly.
"DriftingCloud is an effective, well equipped, and persistent threat actor targeting five-poisons-related targets. They are able to develop or purchase zero-day exploits to achieve their goals, tipping the scales in their favor when it comes to gaining entry to target networks."
Many of you may have already heard of Amit: he is the researcher who made headlines last June, 2017, when he found a workaround solution that disabled the infamous NotPetya Ransomware. Amit is a long time hacker and spends most of his time reverse engineering malware. Prior to his current position in Cybereason, Amit was a member of an Elite cyber unit in the Israeli government.
To understand exactly how Target got hacked, though, all you need to do is picture those bank heist movies. The big bank, the cleaning company, the janitor clothes, the plant. And, just like in the movies: it totally worked.
Prepare your favorite brownie mix according to box directions. While cooling, warm one cup of heavy cream in a heat-safe bowl in the microwave. Heat in 30-second intervals until just boiling. Carefully pour in one 12 oz. bag of semisweet chocolate chips and let sit for a minute. Slowly stir until smooth, glossy and combined. Pour over brownies and top with chopped Archer Farms Peppermint Almonds. Cool until frosting is set.
Known as Operation Cloud Hopper, the attack targeted a small number of managed IT service providers, giving it the potential to spread malware to all the clients using these outsourcing companies to run their computer networks. Companies in 15 countries, including the UK, France, Switzerland, US, Canada, Australia and Japan were targeted.
Although aimed primarily at companies in Ukraine, which has been in conflict with Russia-backed separatists since 2015, the ransomware attack spread far beyond its original target and is estimated to have cost businesses around the world, including the shipping group Maersk and UK-based consumer goods company Reckitt Benckiser, more than $1.2bn in total.
The primary worry for cyber security officials is that state-backed hackers and criminals could penetrate the systems of critical infrastructure organisations such as banks, energy companies and government departments.

The Minneapolis-based chain reported that profit was nearly halved from a year earlier to $520 million and revenue slid 5% to $21.5 billion. Target also racked up $61 million in expenses related to the hack, though it expects all but $17 million of that to be covered by insurance.
Now, however, Visa is warning of a new kind of attack. The elite hacking group known collectively as FIN8 is actively exploiting vulnerabilities in gas station point-of-sale networks to skim card data without the need for modifications at the actual pumps.
