Due to growing traffic in the use of internet and attendant criminal tendencies by some users, the level of phishing attacks again increased in the second quarter of the year with Nigeria and five other countries recording some hits.

 

 

According to a report by Kaspersky, phishing attacks are becoming increasingly more targeted with a number of new tricks being found – from HR dismissal emails to attacks disguised as delivery notifications.

 

The report said as a result of such tendencies, security solutions had detected 2,023,501 phishing attacks in Nigeria, South Africa, Kenya, Egypt, Rwanda and Ethiopia, stressing that these and other findings were documented in Kaspersky’s new spam and phishing in quarter two of 2020.

 

Phishing is one of the oldest and most flexible types of social engineering attacks. They are used in many ways, and for different purposes, to lure unwary users to the site and trick them into entering personal information.

 

The latter often includes financial credentials such as bank account passwords or payment card details, or login details for social media accounts. In the wrong hands, this opens doors to various malicious operations, such as money being stolen or corporate networks being compromised.

 

This makes phishing a popular initial infection method. The report noted that South African users had been influenced the most by this type of threat, with 616,666 phishing attacks detected in three months, followed by Kenya (514,361), Egypt (492,532), Nigeria (299,426), Rwanda (68,931) and Ethiopia (31,585). Phishing is a strong attack method because it is done at such a large scale.

 

By sending massive waves of emails under the name of legitimate institutions or promoting fake pages, malicious users increase their chances of success in their hunt for innocent people’s credentials.

 

The first six months of 2020, however, have shown a new aspect to this well-known form of attack. As Kaspersky analysis has indicated, in Q2 2020, phishers increasingly performed targeted attacks, with most of their focus on small companies.

 

To attract attention, fraudsters forged emails and websites from organisations whose products or services  could be purchased by potential victims. In the process of making these fake assets, fraudsters often did not even try to make the site appear authentic. Such targeted phishing attacks can have serious consequences (https://bit. ly/345ifge).

 

Once a fraudster has gained access to an employee’s mailbox, they can use it to carry out further attacks on the company the employee works for, the rest of its staff, or even its contractors.

 

The news agenda, following the COVID-19 outbreak, has already influenced the “excuses” fraudsters use when asking for personal information. This included disguising their communications with unsuspecting users as: At the peak of the pandemic, organisations responsible for delivering letters and parcels were in a hurry to notify recipients of possible delays.

 

 

These are the types of emails that fraudsters began to fake, with victims asked to open an attachment to find out the address of a warehouse where they could pick up a shipment that did not reach its destination.

 

 

 

Another relatively original move used by fraudsters was a message containing a small image of a postal receipt. The scammers expected that the intrigued recipient would accept the attachment (which, although it contained ‘JPG’ in the name, was an executable archive) as the full version and decide to open it.

 

The Noon spyware was found in mailings such as these examined by Kaspersky researchers. Bank phishing attacks in the second quarter were often carried out using emails offering various benefits  and bonuses to customers of credit institutions due to the pandemic.

 

Emails received by users contained a file with instructions or links to get more details.

 

As a result, depending on the scheme, fraudsters could gain access to users’ computers, personal data, or authentication data for various services.

 

The weakening of the economy during the pandemic in a number of countries caused a wave of unemployment, and fraudsters did not miss this opportunity to strike. Kaspersky experts encountered various mailings that announced, for example, some amendments to the medical leave procedure, or surprised the recipient with the news about their dismissal.

 

In some attachments, there was a Trojan- Downloader.MSOffice.SLoad. gen file. This Trojan is most often used for downloading and installing encryptors. “When summarising the results of the first quarter, we assumed that COVID-19 would be the main topic for spammers and phishers for the past few months. And it certainly happened.

 

While there was the rare spam mailing sent out without mentioning the pandemic, phishers adapted their old schemes to make them relevant for the current news agenda, as well as come up with new tricks,” comments Tatyana Sidorina, security expert at Kaspersky.
