2017: Why Malicious Apps in Official Markets May Increase- ESET

ESET, dedicated to developing high-performing security solutions for home users and corporate customers, detecting and disabling all known and emerging forms of malware, has warned that common occurrence in recent times has been the emergence of malicious apps in the official iOS and Android app repositories.

The Company described the phenomenon as first seemed extremely rare but that has unfortunately become more common over time.

This trend has even affected the Apple App Store, which theoretically has more controls than the Google Play Store for Android, Denise Giusto Bilić, ESET Security Researcher, said in a 2017 IT security trends report released by the company recently.

Bilić identified that as for publishing applications, numerous factors encourage the existence of malicious apps in Google’s app store.

According to her, not only is Android a favorite target for cybercriminals because it has the largest number of potential victims, but the speed at which apps are published on the Play Store also makes it a potential target for many attackers trying to propagate their threats.

She said, “With Android, any developer can create an account with a one-off payment of USD 25, upload an application, and have it published within 24 hours. In contrast, the cost of iOS development membership is more than USD 99 per year and the app approval waiting period can last weeks.

“So while improvements to Bouncer (Google’s module for automatic analysis and malware detection) are made on a regular basis, and manual code analysis is being strengthened, the huge number of new apps that are created daily and the haste with which they are incorporated into the market makes accurate analysis of each one difficult”.

Bilić added that it is possible that in order to reduce future cases of malware introduced into its official app store, Google will need to modify one of these variables—or both—to devote more resources to intensive analysis of a reduced number of applications and/or extend the time needed for the approval process, undermining the speed of publication.

“One of the several strategies Google might use to reduce the number of candidate applications could be raising the price for developers’ accounts.

“What is certain is that so long as the policy framework for publication in the Play Store remains unchanged and none of these corrective measures are taken, we can expect to see a greater amount of malware in official stores in 2017 as attackers double down on this new modus operandi and find new mechanisms to evade detection.

“With regard to this last point, it should be noted that there are many techniques that render mobile malware detection difficult: time bombs, dynamic code executed through reflection, packers, encryption, obfuscated strings, scripts in other programming languages for remote downloading of malicious code, new forms of C&C, anti-emulation, rootkits, etc.

“But above all, cybercriminals are betting and will continue to bet on social engineering, waiting attentively for the official launch of popular apps to distribute their own fake versions, as happened recently with Pokémon GO, Prisma and Dubsmash.

“The speed with which these malicious applications rack up hundreds and even thousands of downloads is a cause for concern among users of the platform. What will happen when cybercriminals decide to greatly increase the complexity of their creations? Users’ different approaches with respect to the installation of applications also plays counterproductive role when it comes to Android”.

Bilić emphasized that the ease with which someone can modify an APK obtained from the official store in order to inject malicious code and distribute it through websites or fake app stores, added to the ease with which users install files from untrustworthy sources, results in a higher rate of malware detection (and in the worst case, infestation) compared to other mobile operating systems.

Nigeria Centre for Disease Control and Prevention (NCDC) has issued a Public Health advisory on the spread of Cerebrospinal Meningitis (CSM).

NCDC Issues Public Advisory on Cerebrospinal Meningitis

It said that the caution is particularly for states within the African Meningitis belt.

In a statement by the Corporate Communications Division of NCDC urged all Nigerians to remain vigilant and adopt preventive measures.

The statement said: “As Nigeria continues through the peak dry season months, the Nigeria Centre for Disease Control and Prevention (NCDC) alerts the public to the ongoing risk of Cerebrospinal Meningitis (CSM), particularly in states within the African meningitis belt.

“Cerebrospinal meningitis occurs more frequently between December and April, when dry, dusty conditions, overcrowding, and poor ventilation increase the risk of transmission.

“The NCDC urges all Nigerians to remain vigilant and adopt preventive measures. Surveillance and response activities remain ongoing nationwide, and laboratory testing is being conducted at the state level while national laboratory capacity is being strengthened.

It explained that Cerebrospinal meningitis is a serious infection of the protective membranes covering the brain and spinal cord.

According to NCDC the affliction is most commonly caused by bacteria, particularly Neisseria meningitidis.

“Bacterial meningitis can progress rapidly and may be fatal within hours if untreated.

“However, early diagnosis and prompt antibiotic treatment significantly improve survival and reduce complications. CSM spreads through respiratory droplets during close contact, especially in overcrowded or poorly ventilated environments.”

It said that symptoms to watch out for include sudden high fever, severe headache, and neck stiffness.

It said other symptoms may include: nausea or vomiting, sensitivity to light, confusion or altered consciousness and seizures.

For In infants and young children, NCDC said the symptoms could bulging soft spot on the head.

The Centre said that early recognition and treatment can save lives.

Report finds the Number of Trojan Banker Attacks on Smartphones Increased by 56% in 2025

According to a Kaspersky report “Mobile malware evolution,” the number of Trojan banker attacks on Android smartphones increased by 56% in 2025 compared to the previous year*.

This type of malware is designed to steal user credentials for online banking, e-payment services and credit card systems. Cybercriminals commonly distribute Trojan bankers through messaging apps, as well as through malicious webpages.

The number of new Trojan banker installation packages for Android (unique APK files) also increased sharply, reaching 255,090 packages – a 271% increase over 2024. This may indicate that these tools generate substantial profit for cybercriminals.

Kaspersky experts believe threat actors will continue both to expand delivery channels and develop new Trojan variants trying to evade detection by security solutions. Among all detected Trojan bankers, the leading families were Mamont and Creduz.

“Although Trojan bankers for smartphones are the fastest-growing type of malware, we also observed another important trend: preinstalled backdoors such as Triada and Keenadu appeared more frequently compared to previous years. People purchase completely new, but infected, Android devices and may be unaware of the threat.

Once integrated into the firmware fully functional preinstalled backdoors provide attackers with unlimited control over the victims’ smartphones and tablets. As a result, all information on infected devices can be compromised.

It’s quite difficult to remove such malware. If the device is infected, we recommend users check for firmware updates. After the update, run a scan of the device with a security solution again to make sure newly installed firmware is not infected,” comments Anton Kivva, malware analyst team lead at Kaspersky.

FG Can Now Track, Prosecute Visa Overstayers – Interior Minister

Federal Government has said it now has the capacity to identify and apprehend foreigners who overstay their visas in the country.

FG Can Now Track, Prosecute Visa Overstayers – Interior Minister

Minister of Interior, Olubunmi Tunji-Ojo

The Minister of Interior, Olubunmi Tunji-Ojo, disclosed this on Thursday in Abuja during the 2026 Sectoral Performance Review Retreat of the Federal Ministry of Interior.

Tunji-Ojo said the government now possesses comprehensive data that enables authorities to track individuals who have entered the country over the past decade and determine those who have failed to comply with their visa conditions.

According to him, the development followed the establishment of an Integrated Operations Centre and a Network Operations Centre by the Nigeria Immigration Service.

The minister, however, said the FG will go after foreigners who have overstayed their visas, adding that outside of the country, Nigerians are not being spared.

He said, “In NIS, I know we are doing a lot already. As of today, we have been able to build our Integrated Operations Centre and the Network Operations Centre, which we never had before.

“With that, we can access, in the last 10 years, everybody who has entered, where you came from, everything, we have all your records, we have everything, we know the exact people who have overstayed in our country, and we will go after them, with due respect, because, outside of Nigeria, they go after the irregular immigrants and we think we have to protect the sanctity of our borders,” the minister stated.”

The minister also stressed the need for reforms across agencies under the ministry, including the Nigeria Security and Civil Defence Corps, to ensure services are delivered transparently and without corruption.

Tunji-Ojo said the goal of government institutions should be to protect citizens, particularly the most vulnerable in society.

NSCDC provides protection in an organised and corruption-free manner, where the son of a nobody will have the same opportunity as the son of anybody in government.

“If you are a businessman or there is a genuine threat to your life, you should be able to access protection without going through the minister, the Commandant General, or anyone else. It is only then that we can truly say we have a service that works for Nigerians.

“Nigeria should not be about selective service delivery. The essence of government is to protect everyone, with greater emphasis on protecting the weakest in society, ” he said.

Speaking on correctional reforms, he argued that a system where individuals repeatedly return to custody reflects a failure of rehabilitation.

“Anybody who goes in there must be reformed and transformed,” he said, adding that the objective was to reduce cases of repeat offences to the barest minimum.

In her remarks, the Permanent Secretary of the ministry, Magdalene Ajani, emphasised the importance of accountability in leadership.

She said leadership was about “devotion, promises, performance, and impact,” noting that the ministry’s agencies play critical roles that affect the daily lives of Nigerians and therefore require transparency and effective service delivery.

The move to go after foreigners who overstay their visas comes amid renewed efforts by the Federal Government to strengthen border management and enforce immigration regulations across the country.

This definitely would allow immigration authorities to track the movement of travellers and identify individuals who remain in Nigeria beyond the duration permitted by their visas.
