Most Dangerous & Latest Android Threats 2023
And for this they deploy Android threats and malware that can extract any kind of data when needed in Android phones. So, today in this article we will be talking about the three most dangerous and latest Android threats in 2023 that affected a huge number of Android users.1. Android Malware Maikspy
This latest Android threat is distributed through an adult game called Virtual Girlfriend. This game is getting much hype on Twitter that is also a primary source of this malware. Maikspy is a dangerous Android malware that is capable of stealing user’s data like personal information and credentials from Android device, which is forwarded to the host server.
This is distributed through fake Twitter accounts that are controlled by the bots. These accounts share a short link that redirects user to website link that is hxxp://miakhalifagame[.]com/.
Through this site malicious app is installed on users’ Android device. And when user tries to uninstall this app, it displays a message ‘Error: 401. App is not compatible. Uninstalling..’. This is done to misguide users that the app has been uninstalled, but it is not.Preventions

A team of malware developers is preparing to sell a new ransomware program that encrypts files on infected computers and asks victims for money to recover them, according to a volunteer group of security researchers who tracked the development of the threat on underground forums in recent weeks.
Like CryptoLocker, PowerLocker allegedly uses strong encryption that cannot be cracked to recover the files without paying, but it’s also more sophisticated and potentially more dangerous because its developers reportedly intend to sell it to other cybercriminals.
Also like CryptoLocker, PowerLocker allegedly uses strong encryption that prevents users from recovering files unless they pay or have backups. However, it’s also more sophisticated and potentially more dangerous because its developers reportedly intend to sell it to other cybercriminals.
Malware Must Die (MMD), a group of security researchers dedicated to fighting cybercrime, spotted a post on an underground forum at the end of November in which a malware writer announced a new ransomware project. That project, initially under the name Prison Locker, later became PowerLocker.
MMD researchers tracked the development of the threat and decided to make the information they gathered public on Friday out of concern that, if completed and released, the new ransomware program could cause a lot of damage. The group published a blog post with screen shots of several underground forum messages describing the malware’s alleged features at various stages of completion, as well as its planned price.
Based on a progress report by the malware’s main developer—a user with the online identity “gyx”—PowerLocker consists of a single file that’s dropped in the Windows temporary folder. Once run on a computer for the first time, it begins encrypting all user files stored on local drives and network shares, except for executable and system files.
This is similar to how CryptoLocker’s encryption scheme is implemented, but PowerLocker goes even further. Once the encryption stage is done, it disables the Windows and Escape keys and prevents a number of other useful utilities like chúng tôi chúng tôi chúng tôi chúng tôi and chúng tôi from being used.
”While CryptoLocker was tailor-made for a select group of individuals, the PowerLocker as they call it is a tool that would be available for purchase, thus making any script-kiddie a potential attacker.”
The malware is also capable of detecting whether it’s run in virtual machines, sandboxes or debugging environments, a feature designed to prevent security researchers from analyzing it using their usual tools.
Another important difference between CryptoLocker and PowerLocker is that the new threat is supposed to be sold as a crimepack to other cybercriminals.
”While CryptoLocker was tailor-made for a select group of individuals, the PowerLocker as they call it is a tool that would be available for purchase, thus making any script-kiddie a potential attacker,” he said. “If it is real, we expect it to hit really hard.”
“Ransomware is easy money and that’s what cybercriminals are after.”
According to the underground forum messages shared by MMD, the PowerLocker author has partnered with another developer to create the malware’s command-and-control panel and the graphical user interface and is very close to completing them. The developers plan to sell the malware for $100 in Bitcoins per initial build and $25 per rebuild, which is a very accessible price for cybercriminals.
Botezatu expects other similar malware programs to be developed and used this year.
”Trojans like GPcode have set the standard for commercial ransomware, while the ROI [return on investment] rates of the FBI Trojan and CryptoLocker have probably incentivized other cybercriminal groups into joining the ransomware pack,” he said. “Ransomware is easy money and that’s what cybercriminals are after.”
Most malware today is distributed through exploits for vulnerabilities in popular software programs like Java, Flash Player and others, so it is very important to keep all applications up-to-date to prevent infection with ransomware and other threats.
Indoor Tanning Dangerous, Warns MED Prof New report on perils of tanning salons
The title of a congressional report last month said it all: “False and Misleading Health Information Provided to Teens by the Indoor Tanning Industry.” With students already heading to tanning salons before next month’s spring break, Barbara Gilchrest, a School of Medicine professor of dermatology, is echoing the report’s warnings against bronzing on a tanning bed.
The risk of melanoma jumps 75 percent for people who begin indoor tanning before the age of 30, and among people who’ve tanned 10 times or more by that age, the risk of a melanoma diagnosis is six times higher than for those who’ve never tanned inside, according to the report. UVA, a type of ultraviolet (UV) light, from sunlamps, “can be as much as 10 to 15 times more powerful than midday sun,” the report to the House Committee on Energy and Commerce warns. And skin cancer rates have shot up along with the popularity of tanning. “Melanoma is now the most common form of cancer for white women between the ages of 15 and 29 years old,” the report says. “Since 1980, the rate of melanoma in this group has increased by 50 percent.”
Yet congressional investigators posing as teens in calls to salons found that 90 percent denied any health risk to fair-skinned teen girls. More than half said tanning would not increase a fair-skinned teen’s cancer risk. Four out of five salons wrongly insisted that indoor tanning had health benefits, from increasing vitamin D to preventing cancer.
Gilchrest: In general, heavy usage certainly continues through college age, the 16-to-25 age group, very conscious of appearance, very much in the dating game.
I think it’s more socially acceptable for women to actively spend time on improving their appearance. Certainly young men do try to tan. But doing things that consciously are intended to improve your appearance—I think that’s something generally viewed as feminine.
Over the course of a year, we all get a lot of UV light, even in an area like Boston. And nobody applies the proper amount of sunscreen. They apply somewhere between a quarter and a half of what is recommended by the manufacturer. So why is it a big deal in a tanning booth? One reason is there are areas of the body getting exposure in a tanning bed that are probably not getting it otherwise. And the intensity of the UV is probably many times higher. We don’t know, frankly, what that does. It may overwhelm the body’s ability to repair the damage.
I strongly recommend that people not use tanning booths, that it’s dangerous, that it encourages them not to use sunscreen. I would also recommend that people not smoke. Whether it should be against the law gets into how much should be forbidden and how much should be left to people’s judgment after education. But to make it a bit more difficult is a great idea—at a minimum, to have parental approval required for minors, and to go after the tanning parlors that don’t ask for it.
They are probably not up there with the banks, but there is a big tanning lobby, and they spend a lot of money on it. Until the Institute of Medicine report came out last November, industry spokesmen were saying there’s a vitamin D deficiency in the United States, you need to use tanning beds to prevent every condition under the sun. The IOM panel released an analysis of over 1,000 publications and studies and concluded there was absolutely no evidence to support those statements.
One of the problems is that young people think they are immortal. And that by the time they are 30, they should be dead anyway, because it’s disgusting to be 30.
Just as the network security industry braces for a rough year, IT managers are backing off security spending — making for a dangerous mix of circumstances, according to industry analysts.
”People are willing to take more risks than I’ve ever seen before,” says Dan Woolley, a vice president at SilentRunner, a network security company. ”I find it a very bothersome trend since we’re expecting to see a doubling of security incidents this year… The world situation is promoting it. We’re seeing a lot more focused activity coming from locations I would say are not quite so friendly to us.”
Security analysts are widely predicting that incidents will skyrocket in 2003 — everything from Web site defacements to worms, viruses, insider-based attacks and now hactivism.
A recent study by the Aberdeen Group, an industry analyst firm based in Boston, noted that reported security incidents are expected to top 200,000 this year. That’s double the 100,00 reported incidents from 2002. And that’s just what is being reported. Aberdeen analysts say there were 7.9 million unreported incidents last year. That number is expected to hit 15.9 million this year.
And despite the numbers and warnings, analysts and consultants say IT managers simply aren’t planning to spend an increasing amount on security this year. Many are planning on cutting back after increased expenditures that followed the terrorist attacks in September of 2001. And many are simply trying to make due with smaller budgets and a smaller IT staff in a rough economic period.
At least one study, however, predicts that the lull in IT spending shouldn’t be a long one. A recent report by Framingham, Mass.-based IDC shows that the IT security market is expected to double between 2001 and 2006. Analysts are hoping spending picks up sooner than later, but not everyone is convinced it will pick up in time to deal with the security issues coming down the pike this year.
It’s a confluence of circumstances that are creating smaller expenditures in at time of great risk.
”We’re seeing people who say they just can’t see putting more into it at this point,” says Woolley. ”They’ve evaluated the risk and they’ve looked at what it would cost to upgrade, and they’ve decided that they’re protected enough right now. They’re saying they just can’t afford it and they just can’t justify the cost right now. They’ll take the hit.”
Mike Rasmussen, director of research at the Giga Information Group, says IT managers shouldn’t be lulled into a feeling of safety simply because security incidents were relatively light in 2002.
The Slammer worm did heat things up in January. The worm, which was lightweight and fast, speeded across the Internet, slowing down online traffic, disrupting business, taking some services offline and even taking down telephone service in various spots around the world. Analysts say if the Slammer had carried a malicious payload, it could have caused significant and even more expensive damage.
Chris Christianson, an analyst with IDC, says the Slammer worm is nothing compared to what’s expected this year.
”We think there’s going to be a major incident this year — an incident that causes disruption or reduces the availability of the Internet,” he says. ”Slammer was just the beginning. I think there’s going to be a lot more.
”I think it’s a really bad time not to be spending on security,” Christianson adds.
And like other analysts, Christianson says political trouble with Iraq and other countries is expected to spur a new wave of attacks.
”Any time there is a period of heightened world tensions, discontent, or feelings of patriotism or allegiances to either side, we expect cyber attacks,” says George Bakos, senior security expert with the Institute for Security Technology Studies at Dartmouth College. ”It may not necessarily be out-and-out cyber warfare but… Web defacements, using a worm as a denial-of-service agent.”
Bakos says now is the time for IT managers to make sure their systems are fully patched, and that there is security on multiple layers of their networks.
”I think the most bothersome concept is the thought that security is something you invest in one time and it will hold you for a while,” says Bakos. ”I’m fully aware that people are stepping back from spending a little bit. You need a basic understanding of information security… Security will never enhance your bottom line. If it’s well done, it will serve to preserve it.”
Forget Kenny Loggins and let’s take a minute to put the real Danger Zone in perspective.
Flying jets off and on ships has historically been a high peril endeavor. Especially on.
The number of U.S. sailors and Marines that have died in and around aircraft carriers is shocking — 8,500 from 1948 to 1988 (when it was just as safe to fly off a U.S. carrier as a U.S. Air Force tarmac).
More than 12,000 aircraft were lost (both figures were dug up from the Navy Safety Center in an essay on the Navy’s transition to jet aviation included in the U.S. Naval Institute’s One Hundred Years of U.S. Navy Air Power (DISCLAIMER: My day job is working for the Naval Institute).
That number includes the aircraft and airmen lost in combat, but combat losses are tiny compared to the number lost in just attempting to take off and land on a carrier. Here’s several reasons why (before anyone complains, this list is far from exhaustive).
The Ship Doesn’t Stand Still

During flight operations an aircraft carrier has to keep about 30 kts (34 mph) of wind across the deck to help provide a boost to the aircraft taking off. (That’s one of the reason the largest carriers are nuclear powered, to move the ships to generate the wind).
A giant steam catapult under the deck launches planes up to about 170 mph to provide the rest of the go for the aircraft.
So that means landing pilots have to take in to account 100,000 ton ship moving at a speed that will get you a ticket on some residential street.
In addition to going forward, the carrier moves in several other ways. Six to be exact. A ship can move front to back (surge), side to side (sway) and up and down (heave). The ship can rotate along each axis — pitch, roll and yaw respectively.
With that in mind, now imagine attempting to land on the top of a five story building in an earthquake (Or pick another analogy. There’s several to choose from).
The excellent PBS documentary Carrier has a pretty harrowing 20-minute sequence in which USS Nimitz is pitching and rolling and yawing and the F-18 pilots are attempting to land on the flight deck in the dark (one Marine captain lands is F-18C after the fifth or sixth attempt and shows the rest of squadron how bad his hand is shaking).
Little Margin for Error

As large as a carrier is (the patriotic like to say a Nimitz-class carrier is four acres of sovereign U.S. real estate anywhere in the world) the area to land is very small.
A plane landing on a carrier moves from about a 150 mph to zero in seconds. The plane stops by catching a hook on a steel wire connected to giant hydraulic motors underneath the flight deck. Hooking the arresting wire is tough, made tougher when the carrier is in motion (see previous sections on the carrier and how it can move).
The target wires (four on older U.S. carriers three on newer ships) exist in an area a little larger than a football field (317 feet) but you really only want to catch the third wire (second on newer ships).
Miss the wires and then you have to take off down the runway at max power to try and give the landing another go. A pilot comes up short, they risk hitting the back of the carrier. For some of the larger aircraft — like the Navy’s E2 Hawkeye — the width margin for error can only be a foot.
Dangers On the Deck
A well-heeded warning from the Island on the island of museum ship, USS Midway
Written in giant yellow letters on the side of every island (the aircraft control tower looking structure on the right side of the carrier) are the words: Beware of Jet Blasts, Props and Rotors.
Pick a direction and you can encounter any number of dangers.
That means there’s a danger on both sides of an aircraft.
Case in point, Petty Officer J.D. Bridges was a sailor onboard an aircraft carrier in 1991. While training a replacement he was inspecting the hook-up of an A6 Intruder to one of the carrier’s catapult. While moving to the front of the aircraft he got sucked into the Intruder’s jet intake. Bridges was lucky and got wedged in the intake before he was sucked toward the rapidly spinning blades of the engine and the pilots quickly turned off the engine.
He escaped with relatively minor injuries — and maybe the title of luckiest man alive. Rotor and prop wash and jet blasts can easily throw a person over the side. In case of that eventuality, or a downed plane, there’s a search and rescue helicopter constantly on standby.
Fire is also another worry.
The deck is a busy place, full of dangerous things — like bombs, bullets and fuel. In 1967 a Zuni rocket on a F-4 Phantom misfired and started a massive fire onboard USS Forestall. The fire on the deck burned for hours and cost the lives of 134 crewmembers. Metals like magnesium and phosphorus used in munitions can combust causing Delta-class fires. The metals burn at thousands of degrees and are very difficult to put out.
Relative to the Ocean, a Carrier is Pretty Small
Before GPS, it was much harder to find the carrier in the wide ocean. Pilots relied on a combination of inertial navigation, radio communications and good old-fashioned maps. Capt. Jim Lovell — best known as the commander of the ill-fated Apollo 13 space mission — tells a story about returning from a 1954 mission in his McDonnell F2H Banshee night fighter. Due to an electrical failure, Lovell’s instruments went dark in the cockpit. In the middle of the ocean at night with the cockpit lights out he noticed a glimmer of photo luminescent algae that had been stirred up by carrier USS Shangri-La. He followed the trail home and landed safely.
As technologies improve the landing experience is getting better. In 2013 the Navy was able to land an unmanned aircraft completely autonomously using a highly precise GPS system that was tested on the service’s Super Hornets. The Navy is also testing an improved system to land the aircraft in conjunction with the Air Force. Regardless of improvements, landing on a carrier is about as harrowing a day job as man has thought up.
It seems like every week you hear of some sort of cyber attack on a business or government agency, but it shouldn’t really be news to us. These types of attacks are as old as the Internet itself.
Since the time of the earliest computer worms, like the Morris Worm in 1988, these little parasites have been infecting computers and networks around the world. But what are computer worms, and why should we pay attention to them?What Are Computer Worms?
Computer worms are similar to real parasites because they can duplicate themselves across as many hosts as possible. Yet, they do it without causing much damage to the systems they are feeding off.
Hackers transmit these worms to your computer through software or operating system vulnerabilities. They usually arrive as attachments in email or instant messaging. They contain standalone software or files that do not have to attach themselves to any other software program to cause damage.
The goal of a computer worm is to replicate itself and spread those copies to other computers, and they do this without any human interaction. This is what makes them not only dangerous but popular among hackers.
Worms usually carry a “payload,” a piece of code that will make your computer vulnerable to other attacks. Without this payload, the life span of a worm is relatively short. This is because as soon as the worm deploys, it reveals the system weakness that allowed it to enter in the first place. Carrying and deploying a payload gives them another avenue into your system and network.
Some of the most destructive worms still exist today. Hackers simply build upon them to make them harder to detect. Like any form of malware, worms are constantly evolving, making them a threat worth protecting against.Can Worms Ruin My Computer?
What happens if a worm infects your computer? Worms will not corrupt your files or break your computer. Instead, they slow down your computer by sucking up resources or Internet bandwidth.
Just because it won’t destroy your computer, that doesn’t mean it can’t be destructive in other ways. These invaders can modify and delete your files, steal data, and install backdoors. If they are carrying a payload, they can inject additional malicious software onto your computer and allow a hacker to control your computer and its system settings.
Another problem is they spread quickly. In fact, SQL Slammer spread so quickly, it was infecting thousands of vulnerable servers using SQL Server every minute. This is one of the fastest spreading worms, but it does prove that replication can occur rapidly.How Can I Avoid Computer Worms?
Luckily, frequent software and operating system updates make worms less effective than they were when those updates were few and far between. However, you still need to keep your security updated to keep them out. Here are a few tips for keeping worms from burrowing their way into your network.
Have a good anti-malware program such as Kaspersky or Malwarebytes installed on your computer or use Windows Defender.
Turn Autorun off when downloading files from the Internet.
Update your system with any patches that your operating system vendor releases to protect against known worms and other possible security vulnerabilities.
Keep your operating system and anti-virus up to date.
Give up Windows XP and Windows 7 if you are still using them.Have I Already Been Infected?
It’s always a good idea to keep any eye out for signs that your computer may already be infected by a computer worm. Some of the most common symptoms of infection include:
Files suddenly missing or being changed
Sluggish performance (can be entire system or just certain apps)
Sudden spikes in CPU usage
Unexplained hard drive usage (As worms replicate, they use more hard drive storage space.)
The sooner you notice the infection, the sooner you can stop it. Remember, the longer it’s on your system, the more damage it can do.
Worms may not be the most feared type of malware that hackers use, but they are definitely still an issue. Follow the best practices for security on your computer and network, and they shouldn’t be able to infiltrate. If instead, you are seeing the “Antimalware Service Executable” process slowing down your computer, you may want to continue letting it run in the background.
