Fill out the form and our experts will be in touch shortly to book your personal demo. Thank you! Let them know that you will always do your best to explain when they might use what you are teaching them, but that you might not always know.
For example: "Not everything I teach will always make sense to you right away. Upon hearing the "When will I ever use this? But if you give me a list of everything you plan to do and accomplish, I'll do my best to let you know when we cover something that I think you might use. You might need it next week, next year or never. But it is going to be on Friday's test, not because I want to make you miserable, but because at the end of the year, it is going to be on the state test, and if you want to pass, you need to know it.
At one of my seminars on motivating unmotivated students, an algebra teacher gave me a paper he gives to all of his students on their first day in his class. He calls it "Algebra Attitude Adjustment. Why do you even have to take this class? I mean, it is all so unfair. A successful person would figure out a way to use a class like this to his or her advantage.
A successful person would want to take this seemingly bad situation and twist it around. A successful person would take lemons, make lemonade and sell it! The campaign started in November and remained active at least into the new year. New ' NoRelationship' attack bypasses Office email attachment security by editing the relationship files that are included with Office documents.
A relationship file is an XML file that contains a list of essential components in the document, such as font tables, settings, and external links. A number of popular email filters only scan the links contained in the relationship file, rather than scanning the entire document. Avanan has the full story. The attackers are sending emails, supposedly from a Polish bank, telling users to confirm an unknown transaction. R ecipients that click the link get to a spoofed error page.
The PHP code then either downloads a. Scams seeking to harvest online credentials have long tried to replicate known logon pages. But this newly found instance is just about perfect. Researchers at security vendor Myki found a website purporting to use Facebook for sign-on, but are instead providing an exact HTML copy of the logon page.
In total, Zscaler blocked 1. Instead they chain their phishing attacks to improve their chances of success. The malicious code, ' Rising Sun' has source code that links it back to the Lazarus Group — a cybercriminal organization believed to be based out of North Korea that was responsible for the cyberattack against Sony Pictures Entertainment. Highlights this quarter include: Unique phishing reports has remained steady from Q2 to Q3 of , Payment processing firms remained the most-targeted companies, Phishing attacks hosted on secure sites continues its steady increase since and phishing attacks are using redirectors both prior to the phishing site landing page and following the submission of credentials to obfuscate detection via web server log referrer field monitoring.
So how can organizations protect themselves? Expect phishing to continue and ensure all layers of protection, including security awareness training for users, is in place. The men stored the stolen PII on the compromised computers.
The pilfered data was accessed by two of the suspects who then sold or used the information with the help of the third participant. A new phishing campaign in March of spreads malware through emails that claim to have Bitcoin investment updates, according to My Online Security.
The emails direct the victim to download an attachment, which is an [. Microsoft took control of 99 phishing domains operated by Iranian state hackers. The domains had been used as part of spear phishing campaigns aimed at users in the US and across the world.
Court documents unsealed in March revealed that Microsoft has been waging a secret battle against a group of Iranian government-sponsored hackers. The OS maker sued and won a restraining order that allowed it to take control of 99 web domains that had been previously owned and operated by a group of Iranian hackers known in cyber-security circles as APT35, Phosphorus, Charming Kitten, and the Ajax Security Team.
Lower-level employees are the workers most likely to face highly-targeted attacks, according to the online marketing firm Reboot. Businesses and consumers see more than 1. Despite how widely known and damaging these attacks can be, companies still fail to adequately prevent them from happening, according to a June report from Valimail. A new strain of the notorious Dridex malware has been spotted using polymorphism antivirus evasion techniques in phishing emails.
The Dridex credential-stealer that almost exclusively targets financial institutions continues to evolve and now uses application whitelisting techniques to infect systems and evade most antivirus products. Using traditional phishing tactics, victims are lured into clicking on a malicious link that appears to be hosted in SharePoint Online or in OneDrive. To eliminate the malicious access, the app must be disconnected — a completely separate process! These advancements in the way attackers are thinking about phishing to facilitate endpoint infection or credential theft make it necessary for organizations to no longer consider their security solutions as their only line of defense.
A vendor email compromise attack targeted the Special Olympics of New York, leverage their email system to reach their approximately 67K registered families with an adult or child having an intellectual disability. Upon realizing the email had been sent out, a follow-up email was sent, communicating that Special Olympics New York was aware of the hack, that donors should ignore the email, and that no information — other than contact details — was accessed.
The Central Bank of Malta has issued a statement warning people about a bitcoin phishing scam being pushed by a spoofed news website, the Times of Malta reports. The site imitated a legitimate news outlet and attributed fake quotes to real people. The latest cyber attack trend data in the U. Security consulting firm CybSafe analyzed three years of the U. The data was released in January Out of nearly reported data breaches, over — The researchers came across a new version of 16Shop that includes a PayPal kit designed to steal a wide variety of financial and personal information from users who speak English, Japanese, Spanish, German and Thai.
Motherboard reports that SIM swappers are launching phishing attacks against employees at Verizon, T-Mobile, and Sprint in order to hijack customer service tools.
Once they have access to these tools, the hackers can take over phone numbers directly without having to trick an employee into performing each swap for them. The attackers are using phishing pages that spoof the login portals of VPNs that the companies use to access these tools. We saw a new malicious phishing campaign in January that is based on the fear of the Coronavirus , and it's the first of many. The message is obviously not from the CDC and at the time of this writing, there are very very few local cases in America.
Let's hope it stays that way. A new slew of phishing attacks targeting victims interested in Oscar-nominated movies steals credit cards and installs malware. According to the researchers at Kaspersky , over 20 movie-related phishing sites have been identified with over malicious files being offered up as movie downloads.
Leveraging social media and presenting an offer to watch the movie, users are taken for a ride that includes surveys, providing personal details, and collecting credit card information. Plus, see how you stack up against your peers with the new phishing Industry Ben chmarks! The Phish-prone percentage is usually higher than you expect and is great ammo to get budget. There are a number of different techniques used to obtain personal information from users.
As technology becomes more advanced, the cybercriminals' techniques being used are also more advanced. To prevent Internet phishing, users should have knowledge of how the bad guys do this and they should also be aware of anti-phishing techniques to protect themselves from becoming victims.
Think of spear phishing as professional phishing. Classic phishing campaigns send mass emails to as many people as possible, but spear phishing is much more targeted. The hacker has either a certain individual s or organization they want to compromise and are after more valuable info than credit card data. They do research on the target in order to make the attack more personalized and increase their chances of success.
In session hijacking , the phisher exploits the web session control mechanism to steal information from the user. In a simple session hacking procedure known as session sniffing, the phisher can use a sniffer to intercept relevant information so that he or she can access the Web server illegally. Using the most common phishing technique, the same email is sent to millions of users with a request to fill in personal details.
These details will be used by the phishers for their illegal activities. Most of the messages have an urgent note which requires the user to enter credentials to update account information, change details, or verify accounts. Sometimes, they may be asked to fill out a form to access a new service through a link which is provided in the email.
Content injection is the technique where the phisher changes a part of the content on the page of a reliable website. This is done to mislead the user to go to a page outside the legitimate website where the user is then asked to enter personal information. Web based delivery is one of the most sophisticated phishing techniques.
The phisher traces details during a transaction between the legitimate website and the user. As the user continues to pass information, it is gathered by the phishers, without the user knowing about it. Some phishing scams involve search engines where the user is directed to product sites which may offer low cost products or services. There are many fake bank websites offering credit cards or loans to users at a low rate but they are actually phishing sites. Link manipulation is the technique in which the phisher sends a link to a fake website.
Hovering the mouse over the link to view the actual address stops users from falling for link manipulation. In voice phishing, the phisher makes phone calls to the user and asks the user to dial a number. The purpose is to get personal information of the bank account through the phone. Vishing is mostly done with a fake caller ID. Keyloggers refer to the malware used to identify inputs from the keyboard. The information is sent to the hackers who will decipher passwords and other types of information.
To prevent key loggers from accessing personal information, secure websites provide options to use mouse clicks to make entries through the virtual keyboard. A smishing text, for example, attempts to entice a victim into revealing personal information via a link that leads to a phishing website.
A Trojan horse is a type of malware designed to mislead the user with an action that looks legitimate, but actually allows unauthorized access to the user account to collect credentials through the local machine.
The acquired information is then transmitted to cybercriminals. The malware is usually attached to the email sent to the user by the phishers. Once you click on the link, the malware will start functioning. Sometimes, the malware may also be attached to downloadable files. Malvertising is malicious advertising that contains active scripts designed to download malware or force unwanted content onto your computer.
Ransomware denies access to a device or files until a ransom has been paid. Forged websites are built by hackers made to look exactly like legitimate websites. The goal of website forgery is to get users to enter information that could be used to defraud or launch further attacks against the victim. One example is CEO fraud and similar attacks. The victim gets an email that looks like it's coming from the boss or a colleague, with the attacker asking for things like W-2 information or funds transfers.
We have a free domain spoof test to see if your organization is vulnerable to this technique. Hackers use devices like a pineapple - a tool used by hackers containing two radios to set up their own wi-fi network.
If you're not paying attention and access the network controlled by hackers, they can intercept any info you may enter in your session like banking data. Users can be manipulated into clicking questionable content for many different technical and social reasons. For example, a malicious attachment might at first glance look like an invoice related to your job. Hackers count on victims not thinking twice before infecting the network.
Every quarter, KnowBe4 reports on the top-clicked phishing emails by subject line. The data comes from millions of phishing tests our customers run per year. The most recent results reveal Business, Online Services, and HR-relates messages to be the most clicked categories across the globe. Click below to see the full infographic, and see the full post here. Sharing this info with your users is a great way to keep them updated on the types of attacks their peers are currently falling for.
See all of our quarterly phishing email reports here. Over the past few years online service providers have been stepping up their security game by messaging customers when they detect unusual or worrisome activity on their users' accounts. Not surprisingly, the bad guys are using this to their advantage. Many are designed poorly with bad grammar, etc. Consider this fake Paypal security notice warning potential marks of "unusual log in activity" on their accounts.
Hovering over the links would be enough to stop you from ending up on a credentials stealing website. The first example is a fake Microsoft notice, almost identical in appearance to an actual notice from Microsoft concerning "Unusual sign-in activity".
The second example email points users to a phony number instead of kicking users to a credentials phish. HTML attachments aren't seen as often as. JS or. DOC file attachments, but they are desirable for a couple of reasons. First, there is a low chance of antivirus detection since. HTML files are not commonly associated with email-borne attacks. HTML attachments are commonly used by banks and other financial institutions so people are used to seeing them in their inboxes.
Here are a few examples of credential phishes we've seen using this attack vector. Malicious macros in phishing emails have become an increasingly common way of delivering ransomware in the past year. These documents too often get past antivirus programs with no problem. The phishing emails contain a sense of urgency for the recipient and as you can see in the below screenshot, the documents step users through the process. If users fail to enable the macros, the attack is unsuccessful.
Several Facebook users received messages in their Messenger accounts from other users already familiar to them. The message consisted of a single. Users who clicked the file to open it were redirected to a spoofed Youtube page that prompted users to install two Chrome extensions allegedly needed to view the non-existent video on the page. For most users, the two Chrome extensions were used to allow the malware a limited degree of self-propagation by exploiting the "browser's access to your Facebook account in order to secretly message all your Facebook friends with the same SVG image file.
On some users' PCs the embedded Javascript also downloaded and launched Nemucod [PDF], a trojan downloader with a long history of pulling down a wide variety of malicious payloads on compromised PCs. Users unlucky enough to encounter this version of the malicious script saw their PCs being taken hostage by Locky ransomware.
LinkedIn has been the focus of online scams and phishing attacks for a number of years now, primarily because of the wealth of data it offers on employees at corporations.
Malicious actors mine that data to identify potential marks for business email compromise attacks, including wire transfer and W-2 social engineering scams, as well as a number of other creative ruses.
Note that this particular InMail appears to have originated from a fake Wells Fargo account. The supplied link leads to a fairly typical credentials phish hosted on a malicious domain since taken down : It looks like the bad guys set up a fake Wells Fargo profile in an attempt to appear more authentic.
Another similar phish was delivered to an email account outside of LinkedIn: This email was delivered through LinkedIn, as did the URLs used for the several links included in the footer of this email "Reply," "Not interested," "View Wells's LinkedIn profile" :.
Those URLs were obviously auto-generated by LinkedIn itself when the malicious actors used LinkedIn's messaging features to generate this phish, which hit the external email account of the mark as opposed to his InMail box, as was the case in the first phish discussed above.
The employee initially responded, then remembered her training and instead reported the email using the Phish Alert Button, alerting her IT department to the fraud attempt. When the employee failed to proceed with the wire transfer, she got another email from the bad guys, who probably thought it was payday:.
Attacks on mobile devices are nothing new, however they are gaining momentum as a corporate attack vector. Security professionals who overlook these new routes of attack put their organizations at risk.
These are what we have found to be best practices in the prevention of phishing attacks. Note there is no single 'silver bullet' that will protect you, you must take a layered approach to stay secure:.
While it may seem trite to offer a recommendation simply to understand the risks that your organization faces, we cannot overstate the importance of doing just that. Decision makers must understand that they face threats not only from phishing attacks, but also a growing variety of threats across all of their communication and collaboration systems, the personal devices that their users employ, and even users themselves.
Cybercrime is an industry with significant technical expertise, extensive funding, and a rich target environment. As a result, we recommend that an early step for any organization should be the development of detailed and thorough policies that are focused on all of the tools that are or probably will be used in the foreseeable future.
These policies should focus on legal, regulatory and other obligations to encrypt emails and other content if they contain sensitive or confidential data; monitor all communication for malware that is sent to blogs, social media, and other venues; and control the use of personal devices that access corporate systems.
Establishing robust policies will not provide security protection per se, but it can be useful in limiting the number of tools that employees use when accessing corporate resources. In turn, these limitations can be helpful in reducing the number of ingress points for ransomware, other forms of malware, phishing attempts, and other content that could pose a security risk.
Application, OS and system vulnerabilities can allow cybercriminals to successfully infiltrate corporate defenses. Every application and system should be inspected for vulnerabilities and brought up-to-date using the latest patches from vendors.
A useful method for recovering from a ransomware attack, as well as from other types of malware infections, is to restore from a known, good backup taken as close as possible to the point before the infection occurred. Using a recent backup, an endpoint can be reimaged and its data restored to a known, good state with as little data loss as possible.
While this strategy will likely result in some level of data loss because there will normally be a gap between the most recent backup and the time of reimaging, recent backups will minimize data loss if no other remedy can be found. There are good solutions available that can be deployed on-premises or in the cloud that can detect phishing attempts and a variety of other threats.
Every organization should implement solutions that are appropriate to its security infrastructure requirements, but with specific emphasis on the ability to detect, isolate and remediate phishing threats.
While the overall spam problem has been on the decline for the past several years, spam is still an effective method to distribute malware, including ransomware. Next, implement a variety of best practices to address whatever security gaps may exist in the organization.
For example:. Every organization should use historical and real-time threat intelligence to minimize the potential for infection. Real-time threat intelligence can provide a strong defense to protect against access to domains that have a poor reputation and, therefore, are likely to be used by cybercriminals for spearphishing, ransomware and other forms of attack.
Threat intelligence can also be used proactively by security analysts and others to investigate recent attacks and discover previously unknown threat sources.
Moreover, historical threat intelligence — such as a record of Whois data that includes information on who has owned domains in the past — can be useful in conducting cybercrime investigations. Using both real-time and historical domain and IP-based threat intelligence is an important adjunct for any security infrastructure because it offers protection in several ways: There are good solutions available that can be deployed on-premises or in the cloud that can detect phishing attempts, ransomware and a variety of other threats.
Here are some additional tips to share with your users that can keep them safe at the office and at home. As your last line of defense, they need to stay on their toes with security top of mind:.
New phishing scams are being developed all the time. The less you stay on top of them, the easier they are to fall for. Keep your eyes peeled for news about new phishing scams. By finding out about them as early as possible, you will be at much lower risk of getting snared by one. Clicking on links that appear in random emails and instant messages, however, is never a good idea.
